In the construction industry, the role of hydroxypropyl methylcellulose is well known that the main areas of application so few: mortar, putty powder, water-based paint, etc., general mortar greatest demand. Here we mainly talk about it in the application and notice of putty powder. Putty powder in the construction process, often adding hydroxypropyl methyl cellulose, which play water, construction and thickening role in the construction putty powder. Water retention: putty powder so slow evaporation of water, ash, calcium secondary reactions occur in water. Construction of: hydroxypropyl methyl cellulose has a good lubrication, putty powder can make a better workability. Thickening: thickening effect of cellulose suspended play, keep the solution up and down the role of uniform, reflected in its anti-sagging. Hydroxypropyl methyl cellulose will not participate in any chemical reaction, it's just play a supporting role. Putty powder, add water, smear on the wall, which is a chemical reaction, because there are new substances generated in this process, the painting had scraped from the wall putty powder, ground into powder, then apply, to die, because It has formed a new material (calcium carbonate) a. The main ingredient is sierozem: 2, CaO mixture of Ca (OH) and a small amount of CaCO3, CaO + H2O = Ca (OH) 2, Ca (OH) 2 + CO2 = CaCO3 ↓ + H2O ash calcium in water and air Under the effect of CO2 generated calcium carbonate, and hydroxypropyl methyl cellulose is water retention, assisted ash calcium better response, but it itself is not involved in any response. Putty powder is generally hundred thousand viscosity can be, mortar higher requirements, to go with one hundred and fifty thousand viscosity. Moreover, hydroxypropylmethyl cellulose (HPMC) is most important role retains water, followed by a thickener. Putty powder in the construction process, as long as the water retention is good, some of it's low viscosity (7-8 million) is also possible, of course, the viscosity of bigger, relative water retention is better, when the viscosity hydroxypropyl methylcellulose over 100 000, the impact of the viscosity of water retention is not big. For more information, please hydroxypropyl methylcellulose concern "Product Knowledge" section. The company's products cellulose ethers, methyl cellulose, hydroxypropyl methyl cellulose, hydroxyethyl methyl cellulose, redispersible powder, polypropylene fiber, the company has high-quality cellulose and latex powder aspects of professional and technical personnel, and continuously improve product quality and application technology.
