hpmc hydroxypropyl methylcellulose

详情

Purpose:
Used as a thickener, dispersant, binder, excipient, oil resistant coating, filler, emulsifier, and stabilizer in the textile industry. It is also widely used in industries such as synthetic resins, petrochemicals, ceramics, papermaking, leather, pharmaceuticals, food, and cosmetics.

Main purpose:

1. Construction industry: As a water retaining agent and retarder for cement mortar, it makes the mortar pumpable. When applying mortar, gypsum, putty powder, or other building materials as adhesives, it improves the coating performance and prolongs the operational time. Used for pasting ceramic tiles, marble, plastic decorations, pasting reinforcing agents, and can also reduce the amount of cement used. The water retention performance of HPMC ensures that the slurry will not crack due to drying too quickly after application, enhancing the strength after hardening.
2. Ceramic manufacturing industry: widely used as a binder in the manufacturing of ceramic products.
3. Coating industry: As a thickener, dispersant, and stabilizer in the coating industry, it has good solubility in water or organic solvents. As a paint remover.
4. Ink printing: As a thickener, dispersant, and stabilizer in the ink industry, it has good solubility in water or organic solvents.
5. Plastics: used as forming release agents, softeners, lubricants, etc.
6. PVC: Used as a dispersant in the production of PVC, it is the main auxiliary agent for preparing PVC through suspension polymerization.
7. Pharmaceutical industry: coating materials; Membrane material; Speed controlled polymer materials for sustained-release formulations; Stabilizer; Suspension aids; Tablet adhesive; Tackifier
8. Other: Widely used in leather, paper products, fruit and vegetable preservation, and textile industries.

Specific industry applications:
Construction industry

1. Cement mortar: improves the dispersibility of cement sand, significantly improves the plasticity and water retention of the mortar, has an effect on preventing cracks, and can enhance the strength of the cement.
2. Ceramic tile cement: Improve the plasticity and water retention of pressed ceramic tile mortar, enhance the bonding strength of ceramic tiles, and prevent powdering.
3. Coating of refractory materials such as asbestos: used as a suspension stabilizer, flow improver, and also to enhance the bonding force to the substrate.
4. Gypsum concrete slurry: improves water retention and processability, and enhances adhesion to the substrate.
5. Joint cement: added to the joint cement used for gypsum boards to improve fluidity and water retention.
6. Latex putty: Improves the fluidity and water retention of resin latex based putty.
7. Plaster: As a substitute for natural materials, it can improve water retention and enhance bonding strength with the substrate.
8. Coating: As a plasticizer for latex coatings, it plays a role in improving the operational performance and flowability of coatings and putty powder.
9. Spray coating: It has a good effect on preventing the sinking of cement or latex based spraying materials and fillers, improving flowability and spray pattern.
*0. Cement and gypsum secondary products: used as a pressing and forming adhesive for cement asbestos series and other hydraulic substances to improve fluidity and obtain uniform molded products.
*1. Fiber wall: Due to its anti enzyme and anti bacterial properties, it is effective as an adhesive for sand walls.
*2. Other: It can be used as a bubble retention agent for thin cement mortar and mud hydraulic operators.
