Polyvinyl alcohol, abbreviated as PVA, is a water-soluble resin obtained through polymerization and hydrolysis reactions. It boasts numerous excellent properties, such as strong adhesion, outstanding film strength and flexibility, smoothness, and resistance to oil, solvents, wear, and excellent protective colloidal properties. After special treatment, PVA also exhibits superior water resistance. Its applications are extensive, spanning from textiles to electronics and more. Additionally, PVA can be processed into high-quality synthetic fibers, further expanding its application scope.

Polyvinyl alcohol (PVA), as an important polymer, has a wide range of applications. It is commonly used in coatings, adhesives, fiber sizing solutions, and paper manufacturing industries. Additionally, PVA plays a significant role in textiles, pharmaceuticals, construction, and environmental protection. Its unique chemical properties and broad application areas make polyvinyl alcohol an indispensable chemical raw material.

1. Gray calcium-based putty: only a small amount of addition can significantly improve the cohesion strength, adhesion and water resistance of putty coating, reduce the use of gray calcium powder, effectively improve the problem of delamination and scar during grinding, and improve the surface fineness after grinding.

2. Cement-based exterior putty: by accelerating the cement setting speed, the early strength of the putty is improved, the film-forming properties are excellent and the durability is good, even if the batch is thin, it is not easy to fall off powder.

3. Polishing putty (imitation porcelain paint): can significantly enhance the surface film formation, make the coating more dense, hard, bright and washable, only one ton of one kilogram added to see the effect.

4. Neutral Interior Putty: By adding polyvinyl alcohol powder and an appropriate amount of cellulose to heavy calcium, a putty powder can be obtained that surpasses ordinary putty powders of starch-based and 821 types. This putty combines the advantages of lime-based and starch-based putties, while also demonstrating excellent adhesion, flexibility, fine grinding, and durability.

5. Instantaneous glue water powder: polyvinyl alcohol as the main binder, combined with hydroxypropyl methyl cellulose and appropriate thickening complexing additives, can be obtained an environmentally friendly, high bonding strength and suitable for cement gypsum wet wall leveling and separate application of double flying powder glue powder.

6. Dry powder mortar: PVA powder performs well in dry powder mortar. It works synergistically with cellulose ether water retention agent to improve the flexibility and water retention of cement mortar and gypsum building materials, improve bonding strength, and effectively prevent spalling, cracking and hollow drumming.

7. Other applications: polyvinyl alcohol can also be used as thin layer adhesive, flexible adhesive, mineral ash paste, cement additive, etc., widely used in cosmetics, screen photo-sensitive film, coated paper, and other fields.

In recent years, the application fields of polyvinyl alcohol (PVA) have continued to expand, demonstrating new vitality. Besides the stable demand in traditional polymer additives, fabric sizing, adhesives, and pulp and coatings, PVA is constantly exploring new application possibilities. For example, in the biomedical field, PVA, due to its excellent biocompatibility and non-toxicity, is gradually becoming an important raw material for preparing biomaterials. Additionally, in the environmental protection sector, the green and environmentally friendly characteristics of PVA also highlight its potential value in producing eco-friendly materials. These new developments not only enrich the application scenarios of PVA but also inject new momentum into the continuous growth of the PVA market.
