The Applications Of HPMC

This product is industrial-grade HPMC. Its main application is as a dispersant in the production of polyvinyl chloride (PVC), which is a key auxiliary agent in the suspension polymerization process for preparing PVC. Additionally, it is used as a thickener, stabilizer, emulsifier, excipient, water-retaining agent, and film-forming agent in the production of other petrochemical products such as coatings, building materials, paint removers, agricultural chemicals, inks, textile printing and dyeing, ceramics, papermaking, and cosmetics. In the application of synthetic resins, it enables the obtained products to have characteristics such as regular particle size, loose structure, appropriate specific gravity, and excellent processing performance, thereby basically replacing gelatin and polyvinyl alcohol as dispersants. Moreover, in the construction process of the building industry, it is mainly used in mechanized construction such as wall construction, plastering, and joint filling; especially in decorative construction, it is used for bonding tiles, marble, plastic decorations, with high bonding strength and can also reduce the amount of cement. When used in the paint industry as a thickener, it can make the coating layer shiny and fine, without powdering, and improve the leveling performance, etc. Purpose
This product is used in the textile industry as thickening agent, dispersant, adhesive, excipient, oil-resistant coating, filler, emulsifier and stabilizer. It is also widely applied in industries such as synthetic resins, petrochemicals, ceramics, papermaking, leather, medicine, food and cosmetics. Main application purpose

1. Take the required amount of hot water and put it in a container. Heat it up to above 85℃, then gradually add this product while stirring slowly. At first, the cellulose floats on the water surface, but it gradually disperses and forms a uniform slurry. Cool the solution under stirring.
2. Or heat 1/3 or 2/3 of the hot water to above 85℃, add the cellulose, obtain the hot water slurry, then add the remaining amount of cold water, keep stirring, and the mixture obtained will be cooled and ready.
