Building mortar additive--Polyvinyl Alcohol
Polyvinyl alcohol (PVA) is A kind of white, powder, stable, non-toxic water-soluble polymer, which can be quickly dissolved in water at room temperature to form a stable colloid. Water is a good solvent for PVA.Polyvinyl alcohol has good film-making property, the formed film has excellent adhesion, solvent resistance, friction resistance, stretching strength and oxygen resistance.Polyvinyl alcohol has both hydrophilic and hydrophobic functional groups, so it is a material with interface activity, so polyvinyl alcohol can be used as a protective colloid in the reaction of polymer emulsification and suspension polymerization.
The main role
PVA polymer powder is especially suitable for building mortar additives, and methyl cellulose ether water retention agent used together, can improve the flexibility of cement mortar, water retention, improve mortar adhesion.In addition, the friction of mortar can be reduced, so as to enhance the working efficiency and quality.
The main purpose
