Hydroxypropyl methyl cellulose is known as "industrial monosodium glutamate", widely used.Hydroxypropyl methyl cellulose itself also has different types, divided into cold water soluble type and hot soluble type, cold water soluble HPMC is widely used, can be used for internal wall putty powder, cement mortar, liquid construction paint, daily chemicals, etc.Hot-soluble HPMC is generally used for dry powder products, directly mixed with dry powder for uniform use, such as putty powder and mortar.Cold water instant solution products in water retention and product stability is not as good as hot solution, so according to different uses should choose different types.

The higher the definition of hydroxypropyl carboxymethyl cellulose, the better the water solubility.The factors affecting water-solubility of wet cement mortar include viscosity of cellulose ether, dosage, particle size and application temperature.The higher the viscosity of cellulose ether, the better the water solubility.Viscosity is a key parameter of HPMC.Relative to the same commodity, the viscosity measured in different ways is huge, small and even twice the distance.Therefore, in terms of viscosity, it is necessary to carry out in the same test standard.Including temperature, motor rotor, etc.In general, the higher the viscosity, the better the practical effect.However, the higher the viscosity, the higher the content of HPMC, and the lower the solubility of HPMC.This has a negative effect on the compressive strength and construction characteristics of cement mortar.The higher the viscosity, the more obvious the thickening effect of cement mortar.However, unlike the ground, the higher the viscosity, the higher the viscosity of the cement mortar, in addition to the application, it will also show information from the adhesive knife and high property to the sheet.But it is useless to improve the compressive strength of wet cement mortar itself.
