Viscosity characteristics of HPMC aqueous solution
The viscosity of HPMC aqueous solution is mainly affected by product polymerization degree, product concentration in aqueous solution, shear rate and solution temperature. The viscosity of aqueous solution increases with the increase of polymerization degree and concentration of product, and decreases with the increase of shear rate and solution temperature. According to actual needs, salt and safe pesticides can also be added to obtain better viscosity characteristics and application performance. Users should consider the actual situation and economy to select the viscosity specification and addition amount of HPMC.
This product is an industrial grade
HPMC, which is mainly used as a dispersant in the production of PVC. It is a main auxiliary agent for preparing PVC by suspension polymerization. In addition, it is used as thickener, stabilizer, emulsifier, excipient, water retaining agent, film former, etc. in other petrochemical, building materials, paint remover, agricultural chemicals, printing ink, textile printing and dyeing, ceramics, paper making, cosmetics and other products.
The application of hydroxypropyl methylcellulose HPMC in synthetic resin can make the obtained products have the characteristics of regular particles, looseness, appropriate specific gravity, and excellent processing performance, thus basically replacing gelatin and polyvinyl alcohol as dispersants. In addition, in the construction process of the building industry, it is mainly used in mechanized construction such as wall building, plaster and caulking; Especially in decorative construction, it can be used to paste ceramic tiles, marble and plastic decoration, with high adhesive strength and reduced cement consumption.
Hydroxypropyl methylcellulose HPMC is used as a thickener in the coating industry, which can make the coating bright and fine, without powder removal, and improve the leveling performance. Used in plastering gypsum, pasting gypsum, caulking gypsum and water resistant putty can significantly improve its water retention and bonding strength. 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.
The company always adheres to the production and operation policy of "customer demand is the direction we pursue". At present, the company mainly produces more than ten specifications of pharmaceutical excipients and industrial grade products in four series, namely, hydroxypropyl methylcellulose HPMC, hydroxyethyl cellulose HEC, hydroxypropyl starch ether and redispersible latex powder, which are widely used in building materials, ceramics, coatings, daily chemicals, oil fields, agriculture, plastics and other industries. The product quality is stable and reliable, and it sells well in domestic and foreign markets, showing a good image of the company and a good prospect for sustainable development
