Viscosity characteristics of hydroxypropyl methyl cellulose hpmc aqueous solution



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


This product is industrial-grade HPMC, the main purpose is to be used as a dispersant in the production of polyvinyl chloride. It is the main auxiliary for the preparation of PVC by suspension polymerization. In addition, it can be used as thickener, stabilizer, emulsifier, excipient, water retention agent and film-forming agent in the production of other petrochemicals, building materials, paint removers, agricultural chemicals, inks, textile printing and dyeing, ceramics, papermaking, cosmetics and other products. Agent. The application of synthetic resin can make the obtained products have the characteristics of regular particles, looseness, suitable specific gravity, and excellent processing performance, thus basically replacing gelatin and polyvinyl alcohol as dispersants. In addition, in the construction industry construction process, it is mainly used in mechanized construction such as wall building, plastering, caulking, etc.; in special sub-decorative construction, it is used to paste ceramic tiles, marble, plastic decoration, high adhesion strength, but also can be reduced The amount of cement. Used as a thickener in the coating industry, it can make the coating bright and delicate, without powdering, and improve the leveling performance. Used in plastering plaster, plaster plaster, caulking plaster, water-resistant putty can significantly rises its water retention, paste strength, etc. It can also be used in functional ceramics, metallurgy, seed coating agents, water-based inks, cosmetics, electronics, printing and dyeing, paper making, etc.
