1. Chemical name: Hydroxypropyl methylcellulose (HPMC) Hydroxypropyl methylcellulose is a nonionic cellulose ether made of natural polymer cellulose as raw material and through a series of chemical processing. They are a white powder that swells in cold water into a clear or slightly cloudy colloidal solution. It has the properties of thickening, bonding, dispersing, emulsifying, film forming, suspension, adsorption, gel, surface activity, moisture retention and colloid protection. Hydroxypropyl methylcellulose, methylcellulose can be used in building materials, coating industry, synthetic resin, ceramic industry, medicine, food, textile, agriculture, daily chemical and other industries.

Physical and chemical properties: 1. Appearance: white or off-white powder. 2. Particle size; 100 mesh pass rate is greater than 98.5%; 80 mesh pass rate is greater than 100%. 3. Carbonization temperature: 280-300℃ 4, visual density: 0.25-0.70/cm3 (usually around 0.5g/cm3), specific gravity 1.26-1.31. 5. Discoloration temperature: 190-200℃ 6, surface tension: 2% aqueous solution is 42-56dyn/cm.7, soluble in water and some solvents, such as proper proportion of ethanol/water, propanol/water, trichloroethane, etc. Aqueous solutions are surface-active. High transparency, stable performance, different specifications of the product gel temperature is different, the solubility varies with the viscosity, the lower the viscosity, the greater the solubility. The performance of HPMC of different specifications is different, and the dissolution of HPMC in water is not affected by the PH value. 8. The surface activity of HPMC decreases as methoxy content decreases, gel point increases, water solubility decreases, and surface activity decreases. 9. HPMC also has the characteristics of thickening ability, salt resistance, low ash powder, PH stability, water retention, dimensional stability, excellent film formation, and a wide range of enzyme resistance, dispersibility and adhesion. 4. Main uses: This product is industrial-grade HPMC. It is mainly used as a dispersant in PVC production, and is the main additive in the preparation of PVC by suspension polymerization. In addition, it is used as a thickener, stabilizer, emulsifier, excipient, water retention agent, film forming agent, etc. in the production of other petrochemicals, coatings, building materials, paint remover, agricultural chemicals, inks, textile printing and dyeing, ceramics, paper, cosmetics, etc. The application of synthetic resin can make the obtained product have the characteristics of regular particles, loose particles, appropriate specific gravity, excellent processing performance, etc., so it basically replaces gelatin and polyvinyl alcohol as dispersants. In addition, in the construction process of the construction industry, it is mainly used in mechanical construction such as wall building, stucco whitewashing, caulking, etc.; especially in decorative construction, it is used for pasting tiles, marble, plastic decoration, etc., and has high pasting strength and can also reduce the amount of cement used. Used as a thickener in the coating industry, it can make the layer bright and delicate, no powder removal, improve leveling performance, etc. 5. Dissolution method: 1. Take the required amount of hot water, put it in a container and heat it to above 85℃, and gradually add this product with slow stirring. Cellulose initially floats on the surface of the water, but is gradually dispersed to form a uniform slurry, and the solution is cooled by stirring. 2. Or heat 1/3 or 2/3 of hot water to 85- or above, add cellulose to obtain hot water slurry, then add the remaining amount of cold water, keep stirring, and cool the resulting mixture. 6. Precautions for packaging, storage and transportation: Packaged in cardboard barrels lined with polyethylene film, net weight of each barrel: 25kg. Prevent sun, rain and moisture during storage and transportation. 0202 Welcome friends in the building materials industry to inquire! Telephone: 15194115466 (WeChat same number) 0202
