White Powder Hydroxypropyl Methyl Cellulose

White Powder Hydroxypropyl Methyl Cellulose, Hydroxypropyl methylcellulose is a widely used cellulose ether, belonging to natural polymer compounds, with the appearance of white or slightly yellow fine powder, non-toxic and tasteless, easily soluble in water, usually as a thickener, binder, suspending agent and emulsifier, etc., widely used in construction, petroleum, medicine and other fields.
Hydroxypropyl methylcellulose is a cellulose ether obtained by chemical modification of natural cellulose. Its preparation principle is to react natural cellulose with reactants such as propylene oxide and methyl chloride under certain conditions to obtain a derivative. Its preparation process mainly includes the following steps:
1. Pretreatment of natural cellulose: Natural cellulose needs to be pretreated by acid hydrolysis, bleaching, drying and other pretreatments to remove impurities and moisture.
2. Etherification reaction: The pretreated natural cellulose and the reactants are subjected to etherification reaction at a certain temperature and pressure to obtain hydroxypropyl methylcellulose.
3. Separation and purification: After the reaction, the crude hydroxypropyl methylcellulose is obtained by centrifugation, precipitation and drying.
4. Crushing and screening: The crude product is crushed and screened to obtain the final hydroxypropyl methylcellulose product.
Hydroxypropyl methylcellulose has a wide range of applications, and its main uses include the following aspects:
1. Construction field: As a thickener, binder, suspending agent and emulsifier, it is used in cement mortar, gypsum plaster, architectural coatings and other fields to improve the water retention, consistency, adhesion and stability of building materials.
2. Petroleum field: As a filtrate reducer, clay stabilizer and emulsifier in petroleum drilling fluid, it can improve the stability and lubricity of drilling fluid and prevent well wall collapse and oil-water separation.
3. Pharmaceutical field: As a drug carrier and drug stabilizer, it is used to prepare drug suspensions, soft capsules and tablets and other pharmaceutical preparations, which can improve the stability and bioavailability of drugs.
4. Other fields: Hydroxypropyl methylcellulose can also be used in daily chemicals, cosmetics, papermaking, ceramics and other fields as a thickener, binder and suspending agent to improve the quality and performance of products.

PRODUCT IMAGE

Hpmc Hydroxypropyl Methylcellulose Chemical Cellulose is a propylene glycol ether of methylcellulose, in which both hydroxypropyl and methyl groups are combined with the anhydrous glucose ring of cellulose by ether linkages.

Hydroxypropyl Methyl Cellulose(HPMC) is white to off-white fibrous powder or granules. Soluble in water and some organic solvents.

 

Application

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.
