What is the application of HPMC in putty powder, and what causes the formation of bubbles in putty powder?
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 main function of HPMC in putty powder and does it undergo a chemical reaction?
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 relationship between the gelation temperature of hydroxypropyl methylcellulose (HPMC) and something else?
1. Hot water dissolution method: HPMC does not dissolve in hot water, but it can disperse evenly in hot water initially and then rapidly dissolve upon cooling. There are two typical methods described as follows:
(1) Place the required amount of hot water in a container and heat it to approximately 70°C. Gradually add HPMC while stirring slowly. Initially, HPMC will float on the water's surface and gradually form a slurry, which cools down under stirring.
(2) Add 1/3 or 2/3 of the required amount of water to a container and heat it to 70°C. Disperse HPMC according to method (1) to prepare a hot water slurry. Then, add the remaining cold water to the hot water slurry and cool the mixture after stirring.
2. Powder mixing method: Mix HPMC powder with a large amount of other powdered substances using a blender. Afterward, add water for dissolution. In this case, HPMC can dissolve without clumping because each tiny corner of the powder contains only a small amount of HPMC, which dissolves immediately upon contact with water. This method is commonly used in putty powder and mortar production.
Regarding the relationship between viscosity and temperature in HPMC (HPMC viscosity), what should be noted in practical applications?
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.
