Hydroxypropyl methylcellulose knowledge
Hydroxypropyl methylcellulose is white or off-white powder. It is mainly used as a dispersant in the production of polyvinyl chloride. In addition, it is used as a thickener, stabilizer, emulsifier, and film-forming agent in the production of other petrochemicals, coatings, building materials, paint removers, papermaking, and cosmetics.、
The main purpose
1. Construction industry: As a water-retaining agent and retarder of cement mortar, it can make the mortar pumpable. In plaster, gypsum, putty powder or other building materials as a binder to improve spreadability and prolong work time. It can be used as paste tile, marble, plastic decoration, paste reinforcement, and can also reduce the amount of cement. The water-retaining performance of HPMC prevents the slurry from cracking due to drying too quickly after application, and enhances the strength after hardening.
2. Ceramic manufacturing industry: It is widely used as a binder in the manufacture of ceramic products.
3. Coating industry: It is used as a thickener, dispersant and stabilizer in the coating industry, and has good compatibility in water or organic solvents. As a paint remover.
4. Ink printing: It is used as a thickener, dispersant and stabilizer in the ink industry, and has good compatibility in water or organic solvents.
5. Plastics: used as forming release agent, softener, lubricant, etc.
6. Polyvinyl chloride: It is used as a dispersant in the production of polyvinyl chloride, and it is the main auxiliary agent for preparing PVC by suspension polymerization.
7. Others: This product is also widely used in leather, paper products, fruit and vegetable preservation and textile industries.
8. Pharmaceutical industry: coating materials; film materials; rate-controlling polymer materials for sustained-release preparations; stabilizers; suspending agents; tablet adhesives; viscosity-increasing agents
