Main Application:

1,PVA 1788 is mainly used for the feedstock of vinylon fiber.The vinylon staple yarn and vinylon tow-to yarn manufactured from the PVA1788 exhibits white color,high strength,perfect hygroscpy,abrasion resistance,sunshine resistance and corrosion resistance.They can be blended with cotton,wool and glue fiber for weaving separately ,which is widely used for clothing ,tarpaulin ,tire cord ,fishingnets and ropes, and they are also an idea substitute of asbestos.

 

2,PVA1788 also can used in the field of paper manking,especially used as surface sizing.With good adhesion,good filming and strengthing to paper, PVA water solution can be used as surface sizing to substitute casein and starch which is more expensive and easy to be corrosible.The whiteness and gloss of the wove paper coated with PVA solution will be perfect,not easy to be crimped and with lower cost.Therefore,it is widely used in art paper ,craft paper,clothing paper and other high-grade paper.

 

   3,It can also used as paper bonding ,vinyl acetate emusification &polymerization,inorganic binder , construction material additives,inorganic binder,cosmetic,medicine and temporary material additives etc.

 

Usage method:

 

KP  series can be used in powder building materials , after stirring and mixing evenly, it could be use. Addition of advice: 0.3-3%of the total putty powder.

 

KP series use 100-120mesh when product dry glue powder, below 100 mesh it dissolves slow, difficult completely dissolve, when over 120 mesh, it is easy to agglomerate. Dry-mixed mortar use 80-120mesh. Powder putty use above 120 mesh, because below 120 mesh it is difficult to dissolve and make the surface unsmooth.

 

 

 

Package & storage transportation:

 

Packing: kraft paper package with plastic film inside, 20kg&25kg per bag.

 

Store: KP line products should be stock indoor where is dry& well-ventilated, room temperature is 5-30, Stored in batches. do not near the power, prevent humid, avoid sun exposure. strictly prohibit storage with volatile chemicals to prevent adsorption modification.

 

Transportation: when transport KP line products should use clean vehicles and avoid moisture, rain, sun and carry gently to prevent damage.
