Answer: HPMC in the application of putty powder, thickening, water retention and construction of three roles. Thickening: Cellulose can be thickened to suspension, so that the solution to maintain uniform up and down the role of the same, anti-hanging. Water retention: Make putty powder dry slowly, assist ash calcium reaction under the action of water. Construction: cellulose has lubricating effect, can make putty powder has good construction property. HPMC does not participate in any chemical reactions, but only plays an auxiliary role. Putty powder and water, on the wall, is a chemical reaction, because of the formation of new substances, the putty powder on the wall off the wall, ground into powder and then use, will not work, because a new substance (calcium carbonate) has been formed. The main components of ash calcium powder are: Ca(OH)2, CaO and a small amount of CaCO3 mixture,
CaO+H2O=Ca(OH)2 - Ca(OH)2+CO2=CaCO3↓+H2O Ash calcium generates calcium carbonate under the action of CO2 in water and air, while HPMC only holds water to assist ash calcium to react better, and itself does not participate in any reaction.
