HPMC is a non-ionic type of cellulose ether. So, what does "non-ionic" mean?
In the application of HPMC in putty powder, it plays three roles: thickening, water retention, and facilitating construction. Thickening: Cellulose can thicken the mixture, maintain uniform suspension, and prevent sagging. Water retention: It slows down the drying process of putty powder and assists in the reaction of lime and calcium in water. Construction: Cellulose acts as a lubricant, improving the workability of the putty powder. HPMC does not participate in any chemical reactions; it only serves as an auxiliary agent. When putty powder is mixed with water and applied to the wall, a chemical reaction occurs because new substances are formed. However, if the putty powder is scraped off the wall, ground into powder, and reused, it is not suitable because a new substance (calcium carbonate) has already formed. The main components of lime and calcium powder are Ca(OH)2, CaO, and a small amount of CaCO3. The reaction can be represented as: CaO + H2O = Ca(OH)2 — Ca(OH)2 + CO2 = CaCO3 ↓ + H2O. Under the action of water and carbon dioxide in the air, lime and calcium carbonate are formed. HPMC only assists in water retention and the better reaction of lime and calcium; it does not participate in any reactions itself.
What is the recommended viscosity of Hydroxypropyl Methylcellulose (HPMC)?
For putty powder, a viscosity of around 100,000 is generally sufficient, while mortar requires a higher viscosity, around 150,000, to be effective. Moreover, the most important function of HPMC is water retention, followed by thickening. In putty powder, as long as it has good water retention and a lower viscosity (70,000-80,000), it can still be used. Of course, a higher viscosity provides relatively better water retention. However, when the viscosity exceeds 100,000, the impact of viscosity on water retention becomes less significant.
How to choose the appropriate hydroxypropyl methylcellulose (HPMC) for different applications?
1. Interior wall putty powder: Heavy calcium carbonate 800KG, light calcium carbonate 150KG (Starch ether, pure Qing, Peng run soil, citric acid, polyacrylamide, etc., can be added as appropriate).
2. Exterior wall putty powder: Cement 350KG, heavy calcium carbonate 500KG, quartz sand 150KG, latex powder 8-12KG, cellulose ether 3KG, starch ether 0.5KG, wood fiber 2KG.
What is the application of HPMC in putty powder, and what causes the formation of bubbles in putty powder?
The powder loss in putty is mainly related to the quality of the lime powder and has little to do with HPMC. Low calcium content in lime powder and an improper ratio of CaO and Ca(OH)2 in lime powder can both cause powder loss. If there is a slight relationship with HPMC, it would be that poor water retention of HPMC can also contribute to powder loss.
