What is the role of hydroxypropyl methylcellulose? Which industries will use it? I believe everyone is not very familiar with it. Here, Huayi gives you a summary. Which industry uses the hydroxypropyl methylcellulose produced by our factory?
 
1. Construction industry:
 
1. Cement mortar: Improves the dispersion of cement sand, greatly enhances the plasticity and water retention of the mortar, effectively prevents cracking, and can improve the strength of cement.
 
2. Tile cement: Enhances the plasticity and water retention of the tile mortar, improves the bonding strength of the tiles, and prevents powdering.
 
3. Asbestos and other refractory coatings: Acts as a suspending agent and flow improvement agent, and can also enhance adhesion to the substrate.
 
4. Gypsum setting slurry: Improves water retention and processability, enhances adhesion to the substrate.
 
5. Joint cement: Added to the joint cement of gypsum boards to improve flowability and water retention.
 
6. Latex putty: Improves the flowability and water retention of resin latex-based putties.
 
7. Plaster: Used as a paste agent instead of natural materials, it can improve water retention and enhance adhesion to the substrate.
 
8. Coatings: Used as a plasticizer for latex paints, it can improve the handling performance and flowability of the coatings.
 
9. Spraying: Effectively prevents the sinking of cement or latex coatings, improves flowability and spraying methods.
 
10. Secondary products of cement and gypsum: Used as an extruded adhesive for water-hard materials like cement-asbestos, it can improve flowability and provide uniform molded products.
 
11. Fiber walls: Due to its anti-enzyme and antibacterial properties, it is effective as a sand wall adhesive.
 
12. Others: It can be used as a bubble stabilizer (PC version), serving as a thin clay mortar and mud hydraulic operator.
 
2. Chemical industry:
 
1. Polymerization of vinyl chloride and vinyl acetate: Acts as a suspending stabilizer for polymerization, can be used in combination with dispersants and polyvinyl alcohol (PVA) hydroxypropyl cellulose (HPC) to control the distribution of particles.
 
2. Adhesives: Used as an adhesive for wallpaper, replacing starch, and is often used with polyvinyl acetate latex paint.
 
3. Pesticides: Added to pesticides and herbicides, it can enhance adhesion during spraying.
 
Latex: Used to improve the emulsifying stability of asphalt latex and as a thickener for styrene-butadiene rubber (SBR) latex.
 
Adhesives: Used as a molding adhesive for pencils and crayons.
 
3. Cosmetics:
 
1. Shampoo: Improves the viscosity and foam stability of shampoos, detergents, and cleansers.
 
2. Toothpaste: Improves the flowability of toothpaste.
 
Food industry:
 
1. Canned citrus: Prevents citrus from turning white and deteriorating due to decomposition during storage.
 
2. Cold food fruit products: Added to fruit juices, ice cubes, etc., to enhance flavor.
 
3. Sauces: Acts as an emulsifying stabilizer or thickener for sauces and ketchup.
 
4. Cold water coating gloss: Used for storing frozen fish, prevents discoloration and quality degradation, coated with methyl cellulose or hydroxypropyl methylcellulose solution, then frozen in ice.
 
5. Tablet binding agent: Used as a molding adhesive for tablets and granules, the adhesive "simultaneously collapses" (slowly melts and disperses upon ingestion).
 
5. Pharmaceutical industry:
 
1. Packaging: Prepares solutions into organic solvents or aqueous solutions and sprays the prepared particles.
 
2. Slow-release agents: 2-3 grams daily, 1-2 grams per dose, effects visible within 4-5 days.
 
3. Eye drops: Due to the osmotic pressure of the methyl cellulose solution being the same as that of tear fluid, it is less irritating to the eyes and is added as a lubricant in contact with the lens of the eyeball.
 
4. Gel agents: Used as a matrix for jelly-like external applications or ointments.
 
5. Impregnated drugs: Used as a thickener and water-retaining agent.
 
6. Kiln industry:
 
1. Electronic materials: Used as a binder for ceramic electrical insulators and ferrite bauxite magnets, can be used with 1,2-propanediol.
 
2. Glazes: Used for ceramic glazes and enamels, can improve adhesion and processing.
 
3. Refractory mortar: Added to refractory brick mortar or casting materials, can improve plasticity and water retention.
 
Others:
 
1. Fibers: Used as a printing paste for pigments, boron forest dyes, basic dyes, and textile dyes, can be used with thermosetting resins in the corrugated processing of cotton.
 
2. Paper: Used for carbon paper and oil-resistant processing of carbon paper.
 
3. Leather: Used as final lubricant or disposable cement.
 
4. Water-based inks: Added to water-based inks and paints as a thickener and film-forming agent.
 
5. Tobacco: Used as an adhesive for regenerated tobacco.
 
In short: the application of hydroxypropyl methylcellulose
