How to judge the quality of HPMC?
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.
What are the main technical indicators of Hydroxypropyl Methylcellulose (HPMC)?
1. Whiteness: Although whiteness alone does not determine the usefulness of HPMC, higher-quality products usually have better whiteness.
2. Fineness: HPMC is typically available in 80 and 100 mesh sizes, with fewer options in 120 mesh. Finer particles generally indicate better quality.
3. Transmittance: When HPMC is dissolved in water and forms a transparent colloidal solution, higher transmittance indicates fewer insoluble impurities.
4. Specific gravity: Higher specific gravity is generally better. A higher specific gravity is often due to a higher content of hydroxypropyl, which results in better water retention.
