Product Description
Polyvinyl alcohol (PVA) powder series of products is specializedin construction industry as an additive in all kinds of dry powder putty, dry mortar, tile adhesive, especially used for building putty and Mortar, improving the flexibility, water retention and increase viscosity of mortar and putty. It's adhesion very good and used to be widely with paper making, sizing material for textile, adhesive, film, and dry mortar field.
Description of Product   
Appearance: White Powder on Floor
Solubility: Stable in almost all organic solvents. Not dissolved in animal and plant oils and grease.
Dissolving Method  
Pouring a certain amount of water into the dissolving tank, the water
temperature should be below 30 ºC, then start the blender and pour into PVA slowly, the filling speed
with PVA should be keep into 10 kilograms per minutes advisable. Confirm the PVA powder has fully
dispersed (about 10-20 minutes) then heat the solution, and it can be completely dissolved when
heat to 90 ºC about 1 hour.
 
Method of analysis  
Viscosity is measured in 4% aqueous solution at 20ºC. By a Brookfield type
viscosimeter. PH is measured in 4% aqueous solution at 20ºCAsh expressed as Na2O.
Precaution:
a. Do not add PVA directly into hot water to dissolve as there will be agglomeration
b. Do not use naked flame directly for heating
c. Blending is necessary throughout the whole process.
d. Some foam will be created during the dissolving process when the solution is highly concentrated   and blending speed is fast. To prevent foaming, some de-foaming agent such as 0.01-0.05% of octanol or tributyl phosophate (for PVA), or 0.2-0.5% of organic silica latex (PVA), maybe be added before dissolving process.
