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
Thermal insulation mortar putty powder ceramic tile binder for internal and external walls thin layer adhesive flexible adhesive cement additive PVC latex rewetting adhesive for business paste cosmetic mesh plate photosensitive film cement additive rewetting adhesive PVC latex coated paper coating agent long fiber yarn sizing agent zinc plate printing photosensitive film.
