China Application of White Powder HPMC in Putty Powder

Hydroxypropyl methylcellulose is a non-ionic cellulose ether made from refined cotton as a raw material after a series of chemical processes. Abbreviation: HPMC.
In the putty powder, HPMC plays three roles of thickening, water retention and construction. 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 react under the action of water. Construction: The cellulose has a lubricating effect, which can make the putty powder have good construction. HPMC 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. Because new substances are generated, remove the putty powder from the wall and grind it into a powder and reuse it. It will not work because new substances (calcium carbonate) have been formed )
