What is the difference between the cold-water soluble type and the thermal soluble type of hydroxypropyl methylcellulose (HPMC) in the production process?
The cold-water soluble type of HPMC is surface-treated with formaldehyde, allowing it to disperse rapidly in cold water but not truly dissolve. It only dissolves when the viscosity increases. The thermal soluble type does not undergo surface treatment with formaldehyde. A higher dosage of formaldehyde results in faster dispersion but slower viscosity increase, while a lower dosage has the opposite effect.
What is the main use of 1-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.
What are the main raw materials of Hydroxypropyl Methylcellulose (HPMC)?
In simple terms, "non-ionic" refers to a substance that does not ionize in water. Ionization refers to the process in which electrolytes dissolve in specific solvents (such as water or alcohol) and dissociate into freely moving charged ions. For example, table salt we consume daily—sodium chloride (NaCl)—when dissolved in water, ionizes and produces freely moving sodium ions with a positive charge and chloride ions with a negative charge. In other words, when HPMC is placed in water, it does not dissociate into charged ions but exists in molecular form.
What are the formulations for interior and exterior wall putty powder?
The main raw materials for Hydroxypropyl Methylcellulose (HPMC) include refined cotton, chloromethane, epichlorohydrin, and other materials such as soda ash, acid, toluene, isopropanol, etc.
