HPMC use and application

 The main purpose

1. Construction industry: As a water-retaining agent and retarder of cement mortar, it makes 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. Plastic: 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. Pharmaceutical industry: coating materials; film materials; rate-controlling polymer materials for sustained-release preparations; stabilizers; suspending agents; tablet binders; viscosity-increasing agents

8. Others: It is also widely used in leather, paper products, fruit and vegetable preservation and textile industries.

Specific industry application

construction industry

1. Cement mortar: Improve the dispersion of cement-sand, greatly improve the plasticity and water retention of mortar, have an effect on preventing cracks, and enhance the strength of cement.

2. Tile cement: improve the plasticity and water retention of pressed tile mortar, improve the adhesion of tiles, and prevent chalking.

3. Coating of refractory materials such as asbestos: as a suspending agent, fluidity improving agent, and also improves the bonding force to the substrate.

4. Gypsum coagulation slurry: improve water retention and processability, and improve adhesion to the substrate.

5. Joint cement: added to joint cement for gypsum board to improve fluidity and water retention.

6. Latex putty: improve the fluidity and water retention of resin latex-based putty.

7. Stucco: As a paste to replace natural products, it can improve water retention and improve the bonding force with the substrate.

8. Coatings: As a plasticizer for latex coatings, it can improve the operability and fluidity of coatings and putty powders.

9. Spraying paint: It has good effect on preventing the sinking of cement or latex spraying materials and fillers and improving fluidity and spray pattern.

10. Secondary products of cement and gypsum: used as an extrusion molding binder for hydraulic substances such as cement-asbestos, to improve fluidity and obtain uniform molded products.

11. Fiber wall: Due to the anti-enzyme and anti-bacterial effect, it is effective as a binder for sand walls.

12. Others: It can be used as a bubble retaining agent for thin clay sand mortar and mud hydraulic operators.
