Hydroxypropyl methyl cellulose in putty powder, the key is what effect, whether organic chemistry?
HPMC in putty powder thickening, water retention and construction of three functions.
Thickening: methyl cellulose can be concentrated with floating and aqueous solution to maintain uniform function and prevent flow suspension.
Water retention: The interior wall powder is slowly dried and the added lime calcium is reflected in the use of water.
Engineering construction: methyl cellulose has lubricating effect, so that putty powder has excellent engineering structure. HPMC does not participate in all chemical changes, but only complements. Putty powder, on the wall, is a chemical change because there is a new chemical transformation, putty powder comes out of the wall, ground out the powder, and reused because the new chemical (calcium carbonate) has been produced. The main components of calcium fly ash are Ca(OH)2,Cao and a small amount of Caco3 compounds, Caoh2oCa(OH)2-Ca(OH) 2cacO3H2O lime can be converted to calcium bicarbonate in water and gas, while MPC is only a strong reflection of water-soluble calcium fly ash, it does not participate in any reflection.
What is hydroxypropyl methyl cellulose main raw material?
Refined cotton, chloromethane, propylene oxide, other raw materials, alkali, acid, toluene, isopropyl alcohol, etc.
Ceramic tile binder why use high viscosity hydroxypropyl methyl cellulose, what effect it has: hydroxypropyl methyl cellulose in putty powder has better thickening, in cement mortar and glue have good water retention and cohesiveness. Excellent wettability, dispersibility, cohesiveness, thickening, emulsification, water retention and film formation, and oil impermeability. Danzhai hydroxypropyl methyl cellulose agent supply dispersant and stabilizer in large quantities. Ionic CMC is mainly used in synthetic detergent spinning. Also widely used in synthetic resin, petrochemical, ceramic, paper, leather, food and cosmetics and other industries.
