1. Construction Industry:
1. Cement mortar: Improves the dispersibility of cement sand, greatly enhances the plasticity and water retention of mortar, effectively prevents cracks, and can increase the strength of cement.
2. Tile cement: Improves the plasticity and water retention of pressed tile mortar, increases the bonding strength of tiles, and prevents powdering.
3. Asbestos and other refractory coatings: Acts as a suspending agent and flow improver, and also enhances adhesion to the substrate.
4. Gypsum setting slurry: Improves water retention and workability, and enhances adhesion to the substrate.
5. Joint cement: Added to gypsum board joint cement to improve fluidity and water retention.
6. Latex putty: Improves the fluidity and water retention of resin latex-based putty.
7. Plaster: Used as a paste substitute for natural materials, it can improve water retention and adhesion to the substrate.
8. Paints: Used as a plasticizer for latex paints, it improves handling properties and fluidity of the paint.
9. Spraying: Effectively prevents sinking of cement or latex coatings, improves fluidity and spraying methods.
10. Secondary cement and gypsum products: Used as an extrusion molding adhesive for cement-asbestos and other hydraulic materials, improving fluidity and providing uniform molded products.
11. Fiber walls: Effective as a sand wall adhesive due to its enzyme resistance and antibacterial properties.
12. Others: Can be used as a foam stabilizer (PC version), acting as a thin clay mortar and slurry hydraulic operator.

2. Chemical Industry:
1. Polymerization of vinyl chloride and vinyl: Used as a suspension stabilizer in polymerization, can be combined with dispersants such as polyvinyl alcohol (PVA) and hydroxypropyl cellulose (HPC) to control particle size and distribution.
2. Adhesives: Used as wallpaper adhesive, replacing starch, commonly used with vinyl acetate emulsion paint.
3. Pesticides: Added to pesticides and herbicides to improve adhesion during spraying.
4. Latex: Used to improve the emulsification stability of asphalt latex and as a thickener for styrene-butadiene rubber (SBR) latex.
5. Adhesives: Used as a molding adhesive for pencils and crayons.

3. Cosmetics:
1. Shampoo: Improves viscosity and foam stability of shampoos, detergents, and cleansers.
2. Toothpaste: Improves the flow properties of toothpaste.

4. Food Industry:
1. Canned citrus: Prevents whitening and deterioration of citrus during storage due to decomposition.
2. Frozen fruit products: Added to fruit syrups, ice cubes, etc., to enhance flavor.
3. Sauces: Used as an emulsifying stabilizer or thickener for seasoning sauces and ketchup.
4. Cold water coating and glazing: Used for frozen fish storage to prevent discoloration and quality degradation; coated with methylcellulose or hydroxypropyl methylcellulose aqueous solution, then frozen on ice layers.
5. Tablet binders: Used as molding binders for tablets and granules, binders that "disintegrate simultaneously" (slowly melt and disperse when taken).

5. Pharmaceutical Industry:
1. Packaging: Prepare solutions in organic solvents or aqueous solutions and spray the prepared granules.
2. Slow-release agents: 2-3 grams daily, 1-2 grams per feed dose, showing effects within 4-5 days.
3. Eye drops: Because the osmotic pressure of methylcellulose solution is the same as that of tears, it causes less eye irritation and is added as a lubricant in contact with the eyeball lens.
4. Jelly agents: Used as a jelly-like base for topical applications or ointments.
5. Impregnation drugs: Used as a thickener and water retention 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-propylene glycol.
2. Glaze: Used for ceramic glazes and enamels, improving adhesion and processing.
3. Refractory mortar: Added to refractory brick mortar or casting furnace materials to improve plasticity and water retention.

Others:
1. Fibers: Used as printing paste for pigments, boron forest dyes, basic dyes, and textile dyes; can be used with thermosetting resins in processing corrugated kapok.
2. Paper: Used for carbon paper and oil-resistant processed carbon paper.
3. Leather: Used as final lubricant or one-time cement.
4. Water-based inks: Added to water-based inks and printing inks as thickeners and film formers.
5. Tobacco: Used as a binder for reconstituted tobacco.
