Hydroxypropyl methylcellulose (HPMC) plays a role in thickening, water retention and construction in putty powder.
Thickening: Cellulose can thicken to suspend, keep the solution evenly up and down, and resist sagging.
Water retention: Make the putty powder dry slower, and help the gray calcium to react chemically under the action of water.
Construction: Cellulose has a lubricating effect, which can make putty powder have good construction properties.
PMC does not participate in any chemical reaction, only plays an auxiliary role. Adding water to the putty powder and putting it on the wall is a chemical reaction that generates new substances. The main components of gray calcium powder are: a mixture of Ca (OH) 2, CaO and a small amount of CaCO3, CaO + H2O = Ca (OH) 2-Ca (OH) 2 + CO2 = CaCO3 ↓ + H2O gray calcium in water and air Under the action of CO2, calcium carbonate is formed, while HPMC only retains water and assists the better response of gray calcium. It does not participate in any reaction itself.
