What are the functions of polyvinyl alcohol powder? Where can it be applied?

Polyvinyl alcohol powders are widely used in construction, coatings, adhesives, and other fields.

Product application:

• Calcium ash-based putty: A very small amount of putty can significantly improve the cohesion strength, adhesion and water resistance of the putty coating, reduce the amount of calcium ash powder, and significantly improve the phenomenon of delamination and scarring during grinding. Improve the surface fineness of putty after polishing.
• In cement-based exterior wall putty: It can increase the speed of cement setting, improve the early strength of putty, have good film formation, excellent durability, and is not easy to remove powder when batched thin.
• Polishing putty (imitation porcelain paint): It can improve the surface film formation, making the coating surface denser, harder, brighter, and more resistant to scrubbing. Adding only one kilogram per ton can achieve obvious results.
• Neutral putty for interior walls: 6 kg of polyvinyl alcohol powder is added to one ton of heavy calcium, and an appropriate amount of cellulose (hydroxypropyl, carboxymethyl) can be used to obtain ordinary putty powder with far better quality than starch and 821 types. The hardness of this putty is between the gray calcium-based putty and the starch putty, and it has excellent batch scraping. The adhesion, flexibility, grinding fineness and durability of the two putties are far inferior. If combined with gypsum powder and retarding technology, a higher grade of excellent home improvement putty powder can be obtained. This putty powder has a long service life and good decorative effect, and will become the development direction of the putty industry in the future.
• In instant glue powder, it is the main binder. It is combined with an appropriate amount of hydroxypropyl methylcellulose and supplemented with an appropriate amount of thickening complexing aids, which can be convenient for environmental protection, high bonding strength, and can be mixed with cement gypsum for wet wall leveling. It can also be used as a separate batch of high-performance glue powder without powder removal.
• In dry mortar. PVA1788 powder has good film-forming properties. It is used in combination with cellulose ether water-retaining agents to improve the flexibility and water retention of various cement mortars and gypsum building materials, improve the bonding strength of the mortar, and effectively prevent peeling, cracking, and hollowing.
