What is the recommended viscosity of Hydroxypropyl Methylcellulose (HPMC)?
For putty powder, a viscosity of around 100,000 is generally sufficient, while mortar requires a higher viscosity, around 150,000, to be effective. Moreover, the most important function of HPMC is water retention, followed by thickening. In putty powder, as long as it has good water retention and a lower viscosity (70,000-80,000), it can still be used. Of course, a higher viscosity provides relatively better water retention. However, when the viscosity exceeds 100,000, the impact of viscosity on water retention becomes less significant.
What is the recommended viscosity of Hydroxypropyl Methylcellulose (HPMC)?
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?
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 dosage of HPMC in actual application varies depending on factors such as climate, temperature, local lime and calcium quality, putty powder formulation, and the desired quality specified by the customer. Generally, it ranges between 4 kg to 5 kg. For example, in Beijing, most putty powders use around 5 kg; in Guizhou, it is mostly 5 kg in summer and 4.5 kg in winter; in Yunnan, the dosage is smaller, usually around 3 kg to 4 kg, and so on.
