Hydroxypropylmethylrubicin (HPMC) is a cellulosic material, pulp or cotton that can be used to refine wood pulp. Before alkalization or alkalization process must be destroyed. Mechanical damage may destroy the aggregate structure of the paper cellulose material, thereby reducing the polymerization and crystallinity, increasing its specific surface area, thereby increasing the matrix can be macromolecular ternary and cellulose.
Hydroxymethylcellulose is used as a substrate in oil production. The utility model can complete the utilization of sugar, improve the utilization rate of materials, reduce the residue of substrate in the fermentation liquid, and reduce the cost of waste water treatment. The characteristics of the mixture are conducive to the optimization of batch, fed-batch and continuous fermentation processes, avoiding the manipulation of medium components and dilution rates, and also facilitating the adjustment of fermentation processes. Since HPMC has the same function as other water-soluble ethers, it can be used as a film-forming agent, thickener, emulsifier and stabilizer for latex paint and water-soluble resin paint, with excellent wear resistance, uniform coating and adhesion Focus on improving the surface tension, acid-base stability and compatibility with metallic pigments.
Composition of hydroxypropylmethylcellulose (HPMC) is disordered, but in principle, but substrate loss, base..etherification, dissolution
Agent recovery through centrifugation, washing, drying and touching each environment is inherently rich in basic skills and knowledge.
Auxiliary equipment and through-watch controls will help ensure product quality and a reliable production system. Affects the amount of water in the hypromellose dry-mix mortar’s water-retaining hydroxypropyl methylcellulose ether mortar to promote continuous hydration of cement, mortar and substrate to increase adhesion time.
There is a main effect of water retention, water retention, moisture retention is putty powder, adhesion and lubrication functions. Widely used in the construction industry, paint industry and many other industries, hydroxypropyl methylcellulose is essential for the manufacture of hydroxypropyl methylcellulose. The thermal gelation temperature is significantly higher than that of methylcellulose. Lime and soda have little effect on performance, but can accelerate the dissolution of the matrix and increase the viscosity. When polyvinyl alcohol, starch ether, vegetable gum and hydroxypropyl methylcellulose paint, etc., the stock solution of the above structure. When using mortar, gypsum, putty powder or other materials as adhesive, it can improve workability and prolong working time. Can be used for decoration, paste tiles, marble, plastic and reduce the use of cement false stem. The water-retaining slurry after drying will not crack too quickly, and the strength after curing is improved.
