Viscosity characteristics of hydroxypropyl methyl cellulose aqueous solution

The viscosity of hydroxypropyl methyl cellulose aqueous solution is mainly affected by polymerization degree of product, concentration of product in aqueous HPMC solution, shear rate and solution temperature. The viscosity of aqueous solution increases with the increase of polymerization degree and concentration, and decreases with the increase of shear rate and solution temperature. According to actual needs, salt, and the best insecticide can be added to obtain better viscosity characteristics and application performance. Users should consider the actual situation and economy to choose the viscosity specification and adding amount of hydroxypropyl methyl cellulose.

This product is industrial grade HPMC, mainly used for PVC production as a dispersant, suspension polymerization preparation of PVC main additives. In addition to other petrochemical, building materials, paint removal agent, agricultural chemicals, printing ink, textile printing and dyeing, ceramics, paper making, cosmetics and other products in the production of thickening agent, stabilizer, emulsifier, excipating agent, water retention agent, film forming agent. 

The application in synthetic resin can make the products have the characteristics of regular particles, loose, appropriate specific gravity, excellent processing performance, so as to basically replace gelatin and polyvinyl alcohol as dispersants. In addition, in the construction process of the building industry, mainly used for building walls, stucco, caulking and other mechanized construction; Special sub-decoration construction, used for sticking ceramic tile, marble, plastic decoration, high adhesive strength, but also can reduce the amount of cement. Used as thickener in the coating industry, can make the coating bright and delicate, do not take off powder, improve leveling performance, etc. Used for painting gypsum, paste gypsum, caulking gypsum, water resistant putty can significantly improve its water retention, paste strength, etc. It can also be used in functional ceramics, metallurgy, seed coating agent, water-based ink, cosmetics, electronics, printing and dyeing, paper making and other fields.
