Polyvinyl Alcohol (PVA, sometimes referred to as PVOH, PVAL, CAS no. 9002-89-5) is one of the seldom high-molecular synthetic polymers with water soluble property, which is essentially made from polyvinyl acetate through hydrolysis. The main specification includes the degree of polymerization, the degree of hydrolysis and other special performance (including viscosity, volatile, ash, PH value and purity).
Polyvinyl Alcohol is classified into two groups, depending on the degree of its hydrolysis, one is fully hydrolyzed, and the other is partially hydrolyzed. Hydrolysis levels from 87% to more than 99%.
Polyvinyl Alcohol is odorless, tasteless, translucent, white or cream colored granular powder, it has substantial tensile strength, more flexibility, chemical resistance, water solubility, excellent film forming, biodegradability, stability to temperature variation, non-toxicity, resistance to organic solvents.
Polyvinyl Alcohol(PVA) has been applied in many fields, such as industrial, commercial and food sectors. For various industrial applications it helps enhance the mechanical properties of films because of its high chemical and thermal stability, low manufacturing cost, in the paper industry(as paper coating), PVA can enhance the features and characteristics of paper by coating a film layer onto the whole sheet, in textile industry as textile sizing it is widely used as surface materials, which should be retained on water surface; in food industry, polyvinyl alcohol is used as a moisture barrier film for food supplement tablets, and food packaging materials. (PVA used in high moisture foods in order to retain the overall satisfactory taste, texture and quality of the foods). It has been used to produce many end products, such as resins, surgical threads and so on. It is also applicable in other industries, including polymer recycling, binding, finishing agents, emulsifiers, wood and leather.
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.
