Main uses<>
b This product is industrial grade
, and its main use is polychloride It is used as a dispersant in ethylene production and is the main additive in suspension polymerization preparation. In addition, in the production of other petrochemical coatings, building materials, paint removers, agricultural chemicals, inks, textiles, printing and dyeing, ceramics, paper, cosmetics and other products, it is used as a thickener, stabilizer, emulsifier, excipient, water-retaining agent, film-forming agent, etc. The application in synthetic resin can make the products have the characteristics of regular and loose particles, suitable specific gravity, and excellent processing performance, thus basically replacing gelatin and polyvinyl alcohol as dispersants. In addition, in the construction process of the construction industry, it is mainly used in mechanized construction such as wall building, stucco decoration, and caulking. Especially in decorative construction, it is used to paste ceramic tiles, marble, and plastic decorations. It has high bonding strength and can also reduce the amount of cement. Used as a thickening agent in the coating industry, it can make the layer bright and delicate without powder removal, and improve the leveling performance. <>
br Dissolution method<>
br
br Take the required amount of hot water, put it into a container and heat it to above
℃, gradually add this solution while stirring slowly. The cellulose initially floats on the surface of the water, but is gradually dispersed to form a uniform slurry. The solution is cooled with stirring.
Or heat the hot water to above, add cellulose to obtain a hot water slurry, then add the remaining amount of cold water, keep stirring, and cool the resulting mixture.
