What is the role of hydroxypropyl methyl cellulose? Which industries use it? I believe everyone is not very familiar with it, which industry is our factory production of hydroxypropyl methyl cellulose?
I. Building Chemical Additive industry:
1, cement mortar: improve the dispersity of cement sand, greatly improve the plasticity and water retention of mortar, effectively prevent cracks, can improve the strength of cement.
2, ceramic tile cement: improve the plasticity of pressed ceramic tile mortar, water retention, improve the bond strength of ceramic tile, prevent pulverization.
3, asbestos and other refractory coatings: as a suspension agent, fluidity improver, but also to improve the adhesion to the substrate.
4, gypsum coagulant: improve water retention and processability, improve the adhesion to the substrate.
5, joint cement: added to the gypsum board joint cement to improve fluidity and water retention.
6, latex putty: Improve the fluidity and water retention of resin latex-based putty.
7, plaster: as a paste instead of natural materials, it can improve water retention and improve the adhesion with the base material.
8, paint: as a plasticizer for latex coatings, it can improve the processing performance and fluidity of coatings.
9, spraying: to prevent cement or latex coating sinking, improve the flow and spraying method has a good effect.
10, cement and gypsum secondary products: used as cement - asbestos and other water-hard materials extrusion molding adhesive, can improve fluidity and provide uniform molded products.
11, fiber wall: due to its anti-enzyme and antibacterial effects, it is effective as a sand wall adhesive.
12, other: It can be used as a bubble retention agent (PC version), play the role of thin clay mortar and mud hydraulic operator.
Ii. Chemical Industry:
1, polymerization of vinyl chloride and vinylidene: As a suspension stabilizer for polymerization, dispersants can be used in combination with vinyl alcohol (PVA) hydroxypropyl cellulose (HPC) to control the distribution of particles and particles.
2, adhesive: as the adhesive of wallpaper, instead of starch, usually can be used with vinyl acetate latex paint.
3, pesticides: added to pesticides, herbicides, can improve the adhesion effect of spraying.
4, latex: Emulsifying stabilizer for improving asphalt latex and thickening agent for styrene-butadiene rubber (SBR) latex.
5, adhesive: used as pencil and crayon forming adhesive.
3. Cosmetics:
1, shampoo: improve the viscosity of shampoo, detergent, detergent and foam stability.
2, toothpaste: improve the fluidity of toothpaste.
4. Food Additives Industry:
1, citrus canning: to prevent citrus from turning white and deteriorating due to decomposition during storage.
2, cold food fruit products: add sherbet, ice cubes, etc., to make the taste better.
3, sauce: as a emulsifying stabilizer or thickening agent for sauces and ketchup.
4, cold water coating glazing: used for frozen fish storage, can prevent discoloration, quality decline, coated with methyl cellulose or hydroxypropyl methyl cellulose aqueous solution, and then frozen on the ice.
5, adhesive for tablets: As a molding adhesive for tablets and granules, the adhesive "simultaneously collapses" (slowly melts and disperses when taken).
V. Pharmaceutical Industry:
1, packaging: the solution is prepared into an organic solvent or aqueous solution, and the prepared particles are sprayed.
2, slowing agent: 2-3 grams per day, 1-2G feed amount each time, show the effect in 4-5 days.
3, eye drops: Because the osmotic pressure of methyl cellulose aqueous solution is the same as that of tears, it is less irritating to the eyes, and is added as a lubricant in contact with the lens of the eye.
4, jelly agent: used as a base for jelly-like external use or ointment.
5, impregnating drugs: as a thickening agent, water retention agent.
6. Kiln industry:
1, electronic materials: As a ceramic electrical insulator, the binder of ferrite bauxite magnets can be used with 1.2-propylene glycol.
2, glaze: used as ceramic glaze and enamel, can improve bonding and processing.
3, refractory mortar: added to refractory brick mortar or casting charge, can improve plasticity and water retention.
Others:
1, fiber: used as pigment, boron forest dye, salt base dye, textile dye printing paste, in kapok corrugated processing, can be used with thermosetting resin.
2, paper: used for carbon paper and oil resistant carbon paper processing.
3, leather: used as final lubrication or disposable cement.
4, water-based ink: added to water-based ink, ink, as a thickening agent, film forming agent.
5, tobacco: as an adhesive for recycled tobacco.
