What are the main technical indicators 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.
Regarding the relationship between viscosity and temperature in HPMC (HPMC viscosity), what should be noted in practical 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.
What is the difference between the cold-water soluble type and the thermal soluble type of hydroxypropyl methylcellulose (HPMC) in the production process?
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 main function of HPMC in putty powder and does it undergo a chemical reaction?
Hydroxypropyl Methyl Cellulose, in English: Hydroxypropyl Methyl Cellulose, also known as HPMC or MHPC. Other names: Hydroxypropyl Methyl Cellulose; Cellulose Hydroxypropyl Methyl Ether; Hypromellose; Cellulose, 2-hydroxypropylmethyl Cellulose ether; Cellulose hydroxypropyl methyl ether; Hyprolose.
