Viscosity Characteristics Of HPMC Aqueous Solution

May. 28, 2020

The viscosity of aqueous solution of hydroxypropyl methyl cellulose is mainly affected by the degree of product polymerization, concentration of product in aqueous solution, shear rate and solution temperature. The viscosity of aqueous solution increases with the increase of product polymerization degree and concentration, and decreases with the increase of shear rate and solution temperature.Salt and safe insecticides can also be added to obtain better viscosity characteristics and application performance. Users should consider the actual situation and economy to choose hydroxypropyl methyl cellulose viscosity specifications and addition.

This product is industrial grade HPMC, mainly used as dispersant in polyvinyl chloride production, is the main auxiliary agent of PVC preparation by suspension polymerization. In addition in other petrochemical, building materials, paint remover, agricultural chemicals, printing ink, textile printing and dyeing, ceramics, paper, cosmetics and other products in the production of thickening agent, stabilizer, emulsifier, exciphers, water retention agent, film-forming agent.

Hydroxypropyl methyl cellulose HPMC in the application of synthetic resin, can make the product with particle neat, loose, appropriate specific gravity, good processing performance and other characteristics, which basically replaced gelatin and polyvinyl alcohol as dispersant.In addition, in the construction process of building industry, it is mainly used in the mechanized construction of wall, stucco and caulking. Special child decorates in construction, use as pasting ceramic tile, marble, plastic adornment, stickup intensity is high, still can reduce cement dosage.

Hydroxypropyl methyl cellulose HPMC in the coating industry for thickening agent, can make the coating bright and delicate, do not deduster, improve leveling performance. It can be used to paint gypsum, paste gypsum, caulking gypsum, water - resistant putty to improve its water retention and paste strength. Also can be used in functional ceramics, metallurgy, seed coating agent, water-based ink, cosmetics, electronics, printing and dyeing, paper and other fields.
