Is there any relationship between powder loss in putty and HPMC?
The cold-water soluble type of HPMC is surface-treated with formaldehyde, allowing it to disperse rapidly in cold water but not truly dissolve. It only dissolves when the viscosity increases. The thermal soluble type does not undergo surface treatment with formaldehyde. A higher dosage of formaldehyde results in faster dispersion but slower viscosity increase, while a lower dosage has the opposite effect.
Is there any relationship between powder loss in putty and 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.
Why does hydroxypropyl methylcellulose (HPMC) have an odor?
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 are the differences between HPMC and MC?
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.
