What are the main uses of methylcellulose (MC)?

Methyl Cellulose MC is widely used in construction materials, coatings, synthetic resins, ceramics, medicine, food, textiles, agriculture, cosmetics, tobacco and other industries. MC can be divided into construction grade, food grade and pharmaceutical grade according to the purpose. At present, most of the domestic products are construction grade. In construction grade, putty powder is used in a large amount, about 90% is used for putty powder, and the rest is used for cement mortar and glue.

1. Construction industry: As a water-retaining agent and retarder of cement mortar, it can make the mortar pumpable. In plaster, plaster, putty powder or other construction

The wood acts as a binder to improve spreadability and work time. Used as pasting tile, marble, plastic decoration, pasting enhancer, also

Can reduce cement consumption. The water-retaining performance of MC 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.

construction industry

1. Cement mortar: improve the dispersibility of cement-sand, greatly improve the plasticity and water retention of mortar, have an effect on preventing cracks, and can strengthen

cement strength.

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 cement-asbestos and other hydraulic substances 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 air bubble retaining agent (PC version) for thin clay sand mortar and mud hydraulic operator.

chemical industry

1. Polymerization of vinyl chloride and vinylidene: as a suspension stabilizer and dispersant during polymerization, it can be used with vinyl alcohol (PVA) hydroxypropyl cellulose

(HPC) can be used together to control particle shape and particle distribution.

2. Adhesive: As a adhesive for wallpaper, it can be used together with vinyl acetate latex paint instead of starch.

3. Pesticides: Added to insecticides and herbicides, it can improve the adhesion effect when spraying.

4. Latex: Emulsion stabilizer for asphalt latex, thickener for styrene-butadiene rubber (SBR) latex.

5. Binder: as a forming binder for pencils and crayons.

Cosmetics industry

1. Shampoo: Improve the viscosity of shampoo, detergent, and cleaning agent and the stability of bubbles.

2. Toothpaste: Improve the fluidity of toothpaste.

food industry

1. Canned citrus: prevent whitening and deterioration due to the decomposition of citrus during preservation to achieve freshness preservation.

2. Cold fruit products: add to sherbet, ice, etc. to make the taste better.

3. Seasoning sauce: used as emulsification stabilizer or thickener for sauce and tomato sauce.

4. Cold water coating and glazing: used for frozen fish storage, can prevent discoloration and quality reduction, use methyl cellulose or hydroxypropyl methyl cellulose aqueous solution

After coating and glazing, freeze on ice.

5. Adhesive for tablets: As a forming adhesive for tablets and granules, it has good bonding “simultaneous collapse” (rapidly melts and collapses when taken).

pharmaceutical industry

1. Coating: The coating agent is made into an organic solvent solution or an aqueous solution for drug administration, especially spray coating the prepared granules.

2. Slow down agent: 2-3 grams per day, 1-2G each time, the effect will appear in 4-5 days.

3. Eye drops: Since the osmotic pressure of methylcellulose aqueous solution is the same as that of tears, it is less irritating to the eyes, so it is added to eye drops as a lubricant for contacting the eyeball lens.

4. Jelly: as the base material of jelly-like external medicine or ointment.

5. Dipping medicine: as a thickener and water retention agent.

Kiln industry

1. Electronic material: as a binder for extrusion molding of ceramic electrical seals and ferrite bauxite magnets, it can be used together with 1.2-propylene glycol.

2. Glaze: used as glaze for ceramics and in combination with enamel paint, it can improve bonding and processability.

3. Refractory mortar: Added to refractory brick mortar or pouring furnace materials, it can improve plasticity and water retention.

other industries

1. Fiber: Used as printing dye paste for pigments, boron dyes, basic dyes, and textile dyes. In addition, it can be used together with thermosetting resins in kapok corrugation processing.

2. Paper: used for leather surface gluing and oil-resistant processing of carbon paper.

3. Leather: used as final lubrication or one-time adhesive.

4. Water-based ink: Added to water-based ink and ink, as a thickener and film-forming agent.

5. Tobacco: as a binder for regenerated tobacco.
