The main products of Guangzhou Building Materials Technology Co., Ltd. desert grams involved are as follows: dry-mix mortar industry with a variety of functional additives, such as re-dispersible polymer powders, hydroxyethyl methyl cellulose ether, methyl hydroxypropyl cellulose ether, Powdered Antifoam, water reducing agent, a lubricant, starch ether and the like; various adjuvants architectural coatings industry use, such as hydroxyethyl cellulose ethers, defoamers, dispersing agents, preservatives, styrene-butadiene latex, hydrophobic agents, thickeners, cement leveling agent. The company insists the long-term development strategy of preservatives, willing and sincere service for domestic and international customers to provide product information and technical guidance. The main physical properties of the components of chloromethyl - / iso plug pyrazolone preparations appearance of liquid Odor green clear withdrawal faint odor density d20 / 41.029 + -0.01 grams per milliliter ISO2811-3 active ingredients: minimum 1.5% at 20 degrees viscosity maximum 20mpa.s ISO3219 PH value: 2-4 Flash point: greater than 100 degrees ISO2592 typical characteristics: miscible capacity / solubility in any proportion and water, lower alcohols, glycols and glycol ether mixture will form clear withdrawal The clear solution desert grams Building Materials Co., Ltd. Guangzhou wholesale distribution of hydroxypropyl methyl cellulose, redispersible powder, Latex, superplasticizer, calcium formate, carboxymethyl cellulose, hydroxypropyl starch ethers, stream leveling agents, preservatives, multifunctional additives, coalescent, dispersant, styrene-acrylic emulsion, hydroxyethyl cellulose, thickeners and other products. The company responded to the national call to promote and implement the scientific concept of development, adhere to the production of clean and practical chemical products, customers are welcome to purchase. Sorbic acid, potassium sorbate and calcium sorbate three varieties. Sorbic acid is insoluble in water, but when you use must first be dissolved in ethanol or potassium bisulfate, the use of inconvenient and irritating preservatives which, it is generally not used; calcium sorbate FAO / WHO provisions of its use Fan sorbic Wai small, so I do not often use; potassium sorbate is not their shortcomings, soluble in water, using a wide range, can often be seen in its presence in some drinks, preserved fruit, canned food; here highlights about potassium sorbate: It unsaturated six carbonate; potassium sorbate on the general market sell white or pale yellow granules, the content of 98% - 102%; no odor, or a slight odor, easy to absorb moisture, easily oxidized and become brown, optical, thermal stability, the relative density of 1.363, a melting point of decomposition at 270 ℃, its PH 1% solution: 7-8. Acidic preservative potassium sorbate, having a high antibacterial properties, inhibit mold growth and reproduction; mainly through the inhibition of microbial dehydrogenase in vivo system, so as to achieve growth and play a role in inhibiting corrosion of microorganisms, bacteria, fungi, Yeasts are inhibited; its effect weakened with increasing liquid preservative PH, PH reaches 3:00 peaked antibacterial preservative quality, PH still inhibitory capacity reaches 6:00, but the lowest concentration (MIC) can not bottom 0.2% proof experiment PH: impregnating solution of potassium sorbate 3.2 ratio PH2.4, the shelf life of food products without sterilizing treatment 2-4 times shorter. >] Drops preservatives | Shanwei preservatives | desert grams preservative building materials provided by desert grams Materials Technology Co., Ltd. in Guangzhou.
