What are the main raw materials of Hydroxypropyl Methylcellulose (HPMC)?
HPMC has three functions in putty powder: thickening, water retention, and facilitating construction. It does not participate in any reaction. The formation of bubbles in putty powder can be caused by two reasons: (1) Excessive water content. (2) Applying another layer on top before the bottom layer has dried, which can also lead to the formation of bubbles.
What is the recommended viscosity of Hydroxypropyl Methylcellulose (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.
How to choose the appropriate hydroxypropyl methylcellulose (HPMC) for different applications?
The viscosity of HPMC is inversely proportional to temperature, meaning that viscosity increases as temperature decreases. When we refer to the viscosity of a certain product, it generally refers to the measurement result of its 2% water solution at 20 degrees Celsius.
In practical applications, in regions with large temperature differences between summer and winter, it is advisable to use relatively lower viscosity during winter for better construction. Otherwise, at low temperatures, the viscosity of the cellulose increases, resulting in a heavier feel during application.
Medium viscosity: 75,000-100,000 (mainly used for putty)
Reason: Good water retention.
High viscosity: 150,000-200,000 (mainly used for polystyrene particle insulation mortar powder and foamed glass bead insulation mortar)
Reason: High viscosity, reduces mortar dusting and sagging, improves construction.
However, in general, higher viscosity provides better water retention. Therefore, many dry mortar manufacturers consider using medium-viscosity cellulose (75,000-100,000) instead of low-viscosity cellulose (20,000-40,000) to reduce the dosage and costs.
Regarding the relationship between viscosity and temperature in HPMC (HPMC viscosity), what should be noted in practical applications?
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.
