What is the recommended viscosity of Hydroxypropyl Methylcellulose (HPMC)?
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?
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.
Regarding the relationship between viscosity and temperature in HPMC (HPMC viscosity), what should be noted in practical applications?
HPMC can be divided into two types: instant soluble and heat soluble. Instant soluble HPMC quickly disperses in cold water, disappearing in the water. At this stage, the liquid does not have viscosity because HPMC is only dispersed in the water and not completely dissolved. After about 2 minutes, the viscosity of the liquid gradually increases, forming a transparent and viscous colloidal solution. Heat soluble HPMC tends to agglomerate in cold water but can rapidly disperse in hot water, disappearing in it. As the temperature decreases to a certain point, viscosity slowly appears until a transparent and viscous colloidal solution is formed. Heat soluble HPMC can only be used in putty powder and mortar, as it tends to agglomerate in liquid adhesives and coatings and cannot be used effectively. Instant soluble HPMC has a wider range of applications and can be used in putty powder, mortar, liquid adhesives, and coatings without any restrictions.
What is the main function of HPMC in putty powder and does it undergo a chemical reaction?
The gelation temperature of HPMC is related to its methoxy content. The lower the methoxy content, the higher the gelation temperature.
