Mucous membrane is not irritant, welcome the manufacturers who have great demand to choose to cooperate with Desheng.

If you want to ask which reagent in the biological buffer is the most widely used, then Tris is definitely the seeded player. Tris base (77-86-1) is white crystal particles under normal conditions, acid-base The indicator pH is 7-9. It is an important organic chemical raw material. It is most widely used as a pH regulator to maintain a stable pH in the reaction. However, many people do not know the specific application of pH adjustment. Let Desheng Xiaobian take you to find out!   Application of Tris(hydroxymethyl)aminomethane in eye drops   Eye drops are one of the most commonly used drug formulations for ophthalmological diseases. For many eye diseases, eye drops have a direct and rapid therapeutic effect. Due to the special anatomical and physiological characteristics of the eyes, corresponding requirements are put forward for ophthalmic preparations: the pH of normal tears is 7.2-7.4, and the range of pH tolerated by normal eyes is 5.0-9.0. The pH value of the eye drops will directly affect the eye irritation and the curative effect of the drug. When preparing eye drops, a buffer should be added to adjust the pH of the solution so that it is roughly similar to the tear fluid to reduce the impact on the eyes. Stimulus. Tris(hydroxymethyl)aminomethane is a commonly used pH regulator in eye drops.   Product packaging   Application of TRIS in nucleic acid detection   Nucleic acid testing is an important means to diagnose the new coronavirus. Tris is an additive in the virus preservation solution, the core material for nucleic acid testing. T can maintain the pH of the sample in the virus preservation solution and act as a biological buffer Effects: Viruses and their nucleic acids are more sensitive to environmental pH. Nucleic acids (DNA, RNA) are easily hydrolyzed in acidic solutions, and are more stable in neutral or weakly alkaline solutions. Its other function is to maintain the stability of the nucleic acid released after the lysis of the sample to be extracted to avoid degradation of the nucleic acid, increase the concentration and purity of the nucleic acid, and ensure the accuracy of subsequent nucleic acid detection and analysis operations.   Application of TRIS in cosmetics   You use various skin care products every day, but you don’t know that the commonly used PH regulator in skin care products is tris. PH regulator is actually a neutralizer. Everyone knows that everyone has different skin types. , The suitable cosmetics are also different. The ingredients in many cosmetics are very complex. If you want a suitable pH value, you must use TRIS to adjust, so that the entire raw material composition will not change too much, so that the cosmetics can be applied more gently on the face without irritation.   Desheng Technology is a professional manufacturer of biological buffers. TRIS is the company's advantage. The product has a purity of ≥99% and a high level, which can be used in many fields. Spot supply, the average daily output is ton-level, if you are interested, please click on the official website or call for consultation.

  Carbomer, as an efficient thickening agent, suspending agent and gel matrix, has been widely used in cosmetics. Carbomer 900 series are polymer copolymers of acrylic acid and allyl sucrose or allyl pentaerythritol. According to the relative molecular weight and crosslinking degree of polymers, Carbomer can be divided into many different types. Carbomer 980 is one of carbomer series products.   Carbomer powder and gel   Related research:   The rheological properties and influencing factors of carbomer 980 were studied. The rheological properties of carbomer 980 were affected by various factors such as neutralization type, pH value, concentration, electrolyte and so on. The neutralization properties of carbomer 980 in different neutralization bases were different. Among them, Na0H neutralization carbomer 980 could change the viscosity of the gel in the neutralization process.   The viscosity of carbomer 980 gel is positively correlated with the concentration. The higher the concentration, the higher the viscosity of the gel. The initial pH value of Carbopol 98 with different concentrations before neutralization is different. The higher the concentration is, the lower the initial pH value is.   Carbomer 980 gel is sensitive to electrolyte ions. The presence of electrolyte makes the viscosity of carbomer 980 gel drop sharply, and the two valence ion has greater influence than monovalent ion. The decrease of viscosity of carbomer gel is mainly due to the reduction of the repulsive force of isoelectric charges on the main chain of polymer, thus reducing the actual effective concentration of carbomer in the system.   Different ions have different effects on the viscosity of carbomer gel, which is mainly related to the number of total charges of ions in the solution. The monovalent ions weaken the viscosity of carbomer gel by shielding the charge, resulting in the decrease of the viscosity of carbomer gel. Besides the action of the two valence ion, when the concentration is enough, it will precipitate with carbomer to form a salt substance, which will further affect the gel. The viscosity and transparency of the product.   The effect of 5 different electrolyte ions on the viscosity, pH value and turbidity of carbomer 980 gel was found to be basically the same. The results showed that the electrolyte had a certain correlation with the viscosity, pH value and turbidity of carbomer.   In this study, the rheological properties and influencing factors of carbomer 980 were studied. Because the viscosity of many cosmetics may affect the sensory characteristics of products, which directly affects the acceptance of products by consumers, how to control these rheological parameters becomes a decisive factor in the practical application of cosmetics formula. Different carbomer and appropriate concentration should be selected according to the actual demand of the formula, and the influence of various factors on carbomer system should be considered comprehensively.  

The CAS number of NSP-DMAE-NHS is 194357-64-7, and the molecular formula is C30H26N2O9S. It is a luminescent substrate reagent used in chemiluminescence experiments. Its parent is an acridinium ester. Depending on the substitution group it contains Many derivatives with different characteristics, acridinium ester NSP-DMAE-NHS is one of the more commonly used ones.   There are a total of 6 acridinium ester products with different groups developed and produced by Desheng. Only the acridinium ester NSP-DMAE-NHS has the top sales volume. As long as the inventory is in stock, it will be cleared immediately. This month ends today. , Has been replenished three times but can be sold out in a short time each time. Such a rapid sales rate is indeed unexpected. Next, let's analyze the reasons for the rapid sales of Desheng NSP-DMAE-NHS.   1. Good product quality. Desheng NSP-DMAE-NHS is a golden yellow powder under normal conditions, with a very fine and bulky texture, a purity of more than 98% by HPLC method, no peculiar smell, and good market feedback. NSP-DMAE-NHS is very stable at pH 7.0, and this one adds its water solubility test, which can be performed in water in the detection of antigen nucleic acid. Compared with other acridine salts, acridine hydrazide, NSP-DMAE-NHS has better luminous efficiency     2. Sufficient inventory. This is a very big advantage. Maybe you can find a lot of manufacturer information when you search for NSP-DMAE-NHS manufacturers on the Internet, but when you really want to purchase, you will find that there is real stock In fact, there are very few manufacturers. Many purchasers have searched all the chemical platforms on the Internet and found that there are very few manufacturers with production and R&D capabilities. This will not happen in Desheng. Desheng has a professional R&D team, acridine The pyridine ester chemiluminescence products are all developed and produced by our company, and the inventory is sufficient.     3. The price is favorable and widely used. First of all, Desheng is a professional manufacturer of acridine esters, with a professional R&D and production team. The product quality is guaranteed and the price is relatively more favorable. Secondly, the conventional acridine esters are all with high quantum yield and luminous efficiency. It is higher than other luminescent reagents, has less interference, low background, and is easier to couple. The labeling is simple and stable, and the effect on luminescence performance after labeling is very small. This also makes NSP-DMAE-NHS widely used.   The acridinium ester NSP-DMAE-NHS developed and produced by Desheng is mostly used in other technologies such as chemiluminescence, high performance liquid chromatography, sensor technology and flow injection technology. Because it is in direct emission mode, the analysis speed is relatively fast. The required equipment is simpler than other luminescent reagents, and the sensitivity is very high. It can be widely used in chemical food safety, biomedicine, environmental testing and other fields.

What is nucleic acid detection, that is, after collecting human secretions, under laboratory conditions, through the analysis of virus RNA gene sequence, using PCR amplification method for detection, clinical etiology diagnosis. At present, nucleic acid detection is the most effective method to determine whether the patient is infected with the virus as early as possible, and to detect and treat the virus as early as possible.   Nucleic acid test swabs are divided into two types: nasal swab and pharyngeal swab. During the sampling process, the doctor will use a swab like a cotton swab to wipe the secretion around the pharynx, tonsil or nasal cavity. As long as it is "gently wiped", it is quick and painless. Medical institutions will disinfect the test area, and medical staff will also disinfect their hands to avoid cross infection. Generally speaking, the sampling process is safe and clean, and there is no need to worry about the risk of infection. Two types of virus preservation solution of Desheng   So what are the types of swab preservation solution after sampling? Swab preservation solution can be divided into inactivated and non inactivated. At the beginning, almost all the swab preservation solutions used in the market are direct preservation of live virus, that is, non inactivated swab preservation solution. This preservation method will lead to higher infection risk for medical staff in sampling, transportation and detection. In view of this situation, anti epidemic measures should be taken It is very necessary to use the swab preservation solution to inactivate the virus directly, but it should be noted that: while inactivating the virus, we should also consider whether the preservation solution can stably preserve the integrity of the virus nucleic acid, so as to avoid the degradation of the nucleic acid in the sample before detection, resulting in the "false negative" of nucleic acid detection. The inactivated virus preservation solution produced and developed by Desheng can avoid this problem.   In short, nucleic acid detection swab preservation solution can be divided into two categories. The inactivated swab preservation solution produced and developed by Desheng is a swab preservation solution with cleavage function, which contains cleavage salt of inactivated virus and cleavage protein to protect nucleic acid. Virus preservation and cleavage are completed in one step, and the other is a non inactivated swab preservation solution. On the contrary, it can protect the integrity of virus protein and nucleic acid In addition to nucleic acid detection, it can also be used for virus culture research. The operating environment requirements of the two preservation solutions are not the same. The inactivated environment does not need to be so strict, while the non inactivated environment will have higher requirements because of the risk of virus infection.

When it comes to chemiluminescence, among many luminescence systems, the earliest chemiluminescence phenomenon is actually found in organisms, such as fireflies. By the end of the 19th century, people discovered that simple non-biological organic compounds can also produce chemiluminescence. For example, Lofen base (2,4,5-triphenylimidazole) can emit green light when oxidized by hydrogen peroxide and other reagents in alkaline medium. After that, the analysis of chemiluminescence reagents for acridinium ester derivatives became the 20th century. A popular research content in the 1980s, more and more luminescence reagent manufacturers prefer the use of acridinium esters, and the pace of domestic research is not far behind. Acridine ester chemiluminescence systems are widely used in various inorganic and organic compounds, biological and pharmaceutical analysis fields due to the advantages of no catalyst, mild reaction conditions, and good reproducibility.   However, there are not many manufacturers of acridine esters in China, and there are few good manufacturers. Desheng can keep up with the market development direction and develop acridine ester products that satisfy customers. It is really commendable. A strong scientific research team, strict quality inspection department, and a dedicated chemical reagent luminescence laboratory in a dust-free and sterile environment provide a solid guarantee for the quality of the products. Chemiluminescent acridinium ester There are actually 8 different series of acridinium esters, such as acridinium ester DMAE-NHS, acridinium ester NSP-DMAE-NHS, acridinium salt NSP-SA, acridinium hydrazide NSP-SA-ADH, etc., although they all Acridine ring, but the tested substances are different, and the acridine series used will be completely different. Many buyers often need to purchase three or more different series of acridine esters when purchasing. After asking many manufacturers, It is found that the production capacity of many manufacturers is far from enough, but Desheng will not have this kind of problem, not only the variety is complete, but also the inventory is sufficient. Wuhan Desheng is a professional manufacturer of chemiluminescence reagents. There are not only the above 8 series of chemiluminescence reagents, but also other chemiluminescence products such as luminol and isoluminol, which can fully meet the needs of manufacturers. Compared with other manufacturers, Desheng’s acridine ester products have the characteristics of fast luminescence reaction, high sensitivity and strong stability. Desheng has always been at the forefront of chemiluminescence reagents, and obtained with high-quality quality and good technical services. Has been widely recognized by the industry.

Chemiluminescence immunoassay is currently the most advantageous immunoassay method. The core reagent is the chemiluminescence substrate. For example, the peroxidase substrate luminol and the alkaline phosphatase substrate AMPPD are widely used. There are acridine ester chemiluminescence reagents, which can directly generate chemiluminescence without enzyme catalysis.   Compared with chemiluminescence substrates such as luminol or alkaline phosphatase, acridine ester chemiluminescence reagents have obvious advantages. Its luminescence reaction does not require enzyme catalysis, and the luminescence detection step is simple and easy to automate; and In terms of sensitivity, acridine esters are many times higher than luminol and peroxyoxalate, and can detect a smaller amount and a wider range of detection indicators. Therefore, acridine ester chemiluminescent substrates are also more advanced immunoassay reagents.   What are the advantages of acridine esters compared with other chemiluminescent reagents   Acridine esters have a higher quantum yield. Compared with luminol, its chemiluminescence efficiency is five times or more than that of luminol; secondly, the properties of acridinium esters are more stable, and are affected by other substances in the reaction system. The impact is also smaller and storage is convenient. Thirdly, the chemiluminescence process of acridinium ester has a fast reaction speed, which can cause luminescence in the presence of hydrogen peroxide or other peroxides. The characteristics of the chemiluminescence reaction mechanism of acridinium esters show that the effect of light quenching is small, and the dissociation of the luminescent group and the luminous efficiency during the reaction will not be affected by the length of the connecting arm.   Acridinium esters and their derivatives can realize the chemiluminescence analysis of biological macromolecules such as antigens, antibodies and DNA, and are a kind of excellent chemiluminescence immunoassay labeling reagent. The main principle of action is to mark these biological macromolecules by directly or indirectly interacting with the amino, carboxyl or phosphoric acid groups on the biological macromolecules through the unique substituent groups on the molecular structure.   Among the many chemiluminescence reagents, the price of acridine esters is also the highest, but Desheng still provides luminol, isoluminol and other types of chemiluminescence reagents, which can meet the needs of different experimental detections. The luminescent reagent is not the most advanced, but the appropriate one.

The only difference with imported brands is the price. The spot price of Desun Carbomer is as low as 100 yuan/kg, and the quantity is limited, so I missed waiting for the next batch. It is used for cosmetic raw materials, pharmaceutical gels, hand-washing gels, etc. For details, please contact Desheng website or the phone number reserved on this website. Desun has been committed to the research of polyacrylic acid. In addition to creating serum separation gel series, the carbomer series is also a long-made series.

Carbomer powder   Carbomer products were first produced abroad, and now a foreign brand controls more than 80% of the market. The reason for this situation is nothing more than the gap in technical capabilities. After continuous research and development efforts in recent years, Desheng has finally been able to In some of these types, we have achieved the situation of "people do not have me, others have me superior", but after all, they are still lacking in reputation. The price increase is also to expand the reputation, win by quantity, and hope more customers Be able to know Desheng.

The full name of Tris base is tris(hydroxymethyl)aminomethane. It is a widely used biological buffer. Its hydrochloride solution is not only widely used as a solvent for nucleic acids and proteins, such as TAE and TBE buffers, especially nucleic acid solutions. . It contains primary amines, so reactions related to typical amines occur, such as aldehydes. Tris also complexes with metal ions in the solution.   As a domestic tris manufacturer, Desheng Biotech produces high-purity white crystals in powdered tris. Recently, I received a call from a customer and reported the high temperature situation. The viscosity of the product increased significantly around 126 degrees. The originally dispersed powder gathered into fine particles, and the reaction was carried out in an anhydrous dry reactor, basically eliminating the influence of moisture. Will this change affect product quality?   TRIS base powder   In fact, this involves the effect of temperature on the crystal structure of Tris. The molecular crystal structure responds to changes in externally applied conditions (such as temperature and pressure) in a complex balance between strong intramolecular bonding, moderate intermolecular interactions (such as hydrogen bonds) and weaker intermolecular van der Waals contacts result. Usually we also consider the influence of pressure on the crystal morphology. We have passed the autoclave test. This pressure above 75Mpa obviously affects the crystal shape. The additional thermodynamic requirements for effective space filling become more and more important. However, the pressure of the autoclave usually does not exceed 20Mpa, so the influence of pressure is not discussed here.   Our measurements are all performed using neutron powder diffraction. The characteristic of the crystal structure is the van der Waals interaction between the molecular chain formed by the NH...NH bond. Although hydrogen bonding is the strongest intermolecular contact, most of the sublimation enthalpy may be due to weaker but numerous van der Waals interactions. Analysis of the thermal expansion data based on the phonon frequency determined in the periodic DFT calculation shows that the expansion at very low temperatures is controlled by the external lattice mode, but above 126°C, the influence of the deflection mode of the intramolecular ring also changes Significantly. The main direction of thermal expansion depends on the sensitivity of different van der Waals interactions to distance changes.   The main value of strain generated when pressure is applied is similar to the value determined in the variable temperature study, but it is isotropic because it needs to fill the void under high pressure to minimize the volume. When the temperature is lowered to room temperature, the hydrogen bond between the molecules weakens, the H interaction between the molecules, the interaction between the dipole moments makes the force between the molecules weaker, and the tris presents a loose white powder structure. This is what we are. The shape of the finished product usually seen. The above changes are all physical changes, which are instantaneous changes in the polarity between molecules and do not change the chemical properties of the molecules themselves, so there is no product quality problem. You can use it with confidence.   Desheng Biochemical is a high-tech enterprise focusing on the fields of life science and biotechnology, providing Chinese experts and scholars with a full range of high-quality products. The tris, Tris-HCL, Bicine, CAPS, MOPS, TAPS,HEPES, etc. produced have been widely used in life science basic research, development and application, biotechnology and many other fields. Customers are located in universities, research institutes, hospitals, biotechnology companies and food industry units.

In the aspect of blood vessel additive, it has formed independent intellectual property rights and professional production and research capacity.   To provide products and raw material solutions for more than 100 domestic and foreign manufacturers. Desheng provides 6 different blood coagulants for you to choose from. What are the similarities and differences between these 6 blood coagulants? Let's make a comparison.   Heparin sodium   White amorphous powder, odorless, soluble in water, easy to absorb moisture, average molecular weight of 15000, stable at room temperature. The heparin sodium titer of our company is more than 150 IU / Mg, and the anhydrous titer is more than 160 IU / mg. Other indexes were controlled according to the standard of heparin sodium.   This product is suitable for the collection and anticoagulation of blood samples in clinical biochemical examination and emergency biochemical examination, and also suitable for the collection and anticoagulation of blood samples in some Hemorheology projects.   Heparin sodium is recommended as an anticoagulant in the determination of ion content in blood, because it is the least likely to interfere with the determination of other ions. This product is not a drug and can not be used as an injection. It is forbidden to directly inject into human body and animals.   Heparin lithium   It is also a white amorphous powder, which is replaced on the basis of heparin sodium. It is stable at room temperature. The routine potency of heparin lithium was more than 150 IU / Mg, which was controlled according to the standard of heparin API.   When heparin lithium has impurities, abnormal smell, color and beyond the validity period, and heparin lithium solution appears turbid, it may be that heparin lithium solution has been contaminated or deteriorated, so it is forbidden to use.   Potassium oxalate   White monoclinic crystal, soluble in water, used in medicine and straw hat bleaching; also used as chemical reagent, fabric detergent; used as anticoagulant for venous blood vessel samples.   White crystal powder, odorless, soluble in water, easy to absorb moisture, molecular weight 404.6, pH 4.8 ± 1 (5% aqueous solution, g / ml), water solubility ≥ 60% (g / ml, 25 ℃). It is stable at room temperature. The main content of potassium EDTA in our company is more than 99.0%. Other indicators are shown in the product test report.   When there are impurities, foreign matters, abnormal smell, color, serious moisture absorption and beyond the validity period of EDTA, it is forbidden to use.   Potassium EDTA   This product is specially used for in vitro anticoagulation of blood. It is an anticoagulant additive for clinical blood test. It is used for the pretreatment of blood samples (anticoagulant treatment) in the process of clinical blood collection and test.   This product can be sealed in a cool and dry place, away from light and moisture. The water solution of this product can be sealed at normal temperature under sterile condition. It is suggested that this product should be ready to use in water solution, and should not be stored in solution state for a long time.   Sodium citrate   White crystal powder, easy to absorb moisture, can be used as flavor agent and stabilizer in food and beverage industry; used as anticoagulant, expectorant and diuretic in pharmaceutical industry; used as adjuvant of nontoxic detergent instead of sodium tripolyphosphate in detergent industry; used as excellent chelator / complexing agent in chemistry; used in industry for sodium citrate. It is also used in brewing, injection, photographic medicine and electroplating.

Chemical reagent is a kind of fine chemicals with various purity standards, which can be used for teaching, scientific research, analysis and testing, and can be used as pure and ultra pure functional materials and raw materials for some emerging industries. Generally, it can be classified by composition and purity. It is not only an important tool for modern scientific research and product inspection, but also an indispensable material for emerging technology.   According to the major categories, chemical reagents can be divided into 11 categories: General inorganic reagents, general organic reagents, high-purity inorganic reagents, high-purity organic reagents, general analytical reagents, instrumental analytical reagents, biochemical and molecular biological reagents, clinical laboratory reagents, isotope reagents, special chemicals and other reagents. Chemical reagents can also be divided into high-purity reagents, high-grade pure reagents, analytical pure reagents, etc. The specifications of chemical reagents in China are basically classified according to purity. The quality indicators issued by the state and competent departments mainly include superior grade purity, analytical purity, chemical purity and experimental purity.   Chemical reagents of different colors 1. High grade purity (GR, green label) (grade I): high content of main components, high purity, suitable for analysis and research, some can be used as reference materials. 2. Analytical purity (AR, red label) (grade II): high content of main components, high purity, low interference impurities, suitable for industrial analysis and chemical experiments. 3. Chemical purity (CP, blue label) (grade III): high content of main components, high purity, interference impurities, suitable for chemical experiments and synthetic preparation. 4. Experimental purity (LR, yellow label): high content of main components, poor purity, no choice of impurity content, only suitable for general chemical experiments and synthetic preparation.   In addition to the above four levels, there are: Reference Reagent (PT): specially used as reference material, which can be directly prepared into standard solution. Spectral purity reagent (SP): indicates spectral purity. However, due to the fact that the organic matter can not be displayed in the spectrum, sometimes the principal component is less than 99.9%, so we must pay attention to it when using it, especially when it is used as a reference substance. The reagent whose purity is much higher than that of superior grade is called high purity reagent (I > 99.99%). High purity reagents are developed on the basis of general reagents. High purity reagents are especially suitable for trace analysis.   More than 95% of the biochemical reagents produced and developed by Desheng include chromogenic reagents, biological buffers, blood collection additives, chemiluminescence reagents, etc., which are analytical pure reagents with high purity. The company covers an area of 3000 square meters, has modern clean workshop and advanced production equipment, strong technical force, a number of professional R & D teams, and advanced and complete analytical detectors The perfect quality inspection and quality assurance system ensure that we provide stable high-quality products to the market. We warmly welcome all major enterprises to visit our company.

Carbomer is very common in daily chemical products, but people rarely find it. For example, toothpaste, skin care lotion, and bath shampoo all exist in it. It is even more important in the hand-washing disinfectant gel just needed during the epidemic. This kind of hand sanitizer is not liquid and will not flow randomly, and it has disinfection, Features such as no-washing are very suitable for quick disinfection of hands. As an indispensable raw material in daily chemical products, the annual purchase quantity of Carbomer will naturally not be small. So how to choose a high-quality carbomer supplier? In response to this problem, this article analyzes from the following aspects.   Desun Carbomer powder and gel samples   1. Guarantee products and guarantee services   By investigating related companies, we can find that high-quality carbomer manufacturers can master more advanced technologies, conduct in-depth explorations with customers, and negotiate cooperation related matters. In early 2020, the company invested a lot of capital, manpower and material resources, and now has A group of professional technical personnel can guarantee that the indexes of the raw materials produced by Carbomer are qualified and up to standards, comparable to international brands. Not only that, when encountering quality problems, Desheng never shirks, but promptly returns them. To ensure that the interests of customers are not harmed.   2.guarantee the delivery speed   The quality of the purchased product is the key, and the delivery speed is also what many customers care about. If the delivery is too slow, many important customers will be lost. No matter how good the product quality is, once the delivery cycle is long, the customer experience will be greatly reduced. After the equipment is upgraded and modified, the monthly output can reach the ton level, and the delivery is very timely. Under normal circumstances, placing an order on the same day can guarantee timely delivery on the same day. If the quantity is large, it can basically reach the customer in 3-5 days, so here Don’t worry about it.     3.to ensure a very high product-to-performance ratio   When choosing what kind of carbomer raw material company to cooperate with, the quotation provided by the relevant company is also an important reference standard, especially when the demand for carbomer is large, the corresponding raw material purchase volume will also double. If the supplier can provide a more competitive quotation, there will definitely be more room for maneuverability in terms of cost control. Desheng is the manufacturer of Carbomer, direct sales of raw materials. So compared with other traders, the product cost performance will be higher.   I believe that after reading the above analysis, you will understand how people who really know how to choose carbomer raw materials suppliers, I believe Desheng will be your trusted choice. Now the company has begun to implement mass production, with an average daily output of 1t, and has rich experience in exporting. If necessary, please call for detailed inquiry.
