Application
- Polyvinyl Alcohol(PVA) is a kind of water-soluble resin with good chemical stability. It also has good adhesion, film-forming ability, insulation, oil resistance, abrasion resistance and gas barrier properties, and has typical chemical properties of polyols and can make esterification, etherification, acetalization reactions.
- In textile, PVA 1788 widely used as fabric sizing material, warp size material.Polyvinyl Alcohol(1788) advantage as below:
- 1)PVA 1788 is easy slurry configuration, saving time and fuel cost
- 2)PVA 1788 shows more stable quality and easy operation
- 3)PVA 1788 performs high adhesion, good wear resistance,what can improve weaving efficiency, and can weave high-grade fabrics
- 4)PVA 1788 improves the material yield out and saves cost
- 5)PVA 1788 can make less dropping paste,and lower requirements on the working environment, what would improve the working environment of the workshop
- 6)PVA 1788 doesn't need special desizing agent for desizing. It can be dissolved and removed by using warm water simply to reduce the environmental problems caused by desizing drainage.
- Other applications for Polyvinyl Alcohol 1788
- In lumbering and paper-making industries, they can be used as adhesives;
- In agriculture, they can be used as soil improvers, pesticide adhesion synergist and PVA film;
- In petroleum exploitation, they can be used as well-cementing agents.
