PVA
P
VA, namely polyvinyl alcohol, is a water-soluble polymer. It typically appears as white powder, flakes, or flocculent solids. Chemically, it is produced by the alcoholysis of polyvinyl acetate. The numerous hydroxyl groups in its molecules endow it with excellent hydrophilicity and water solubility. Its characteristics are remarkable: the aqueous solution has high viscosity and film-forming property, and the formed film is flexible with high transparency; it has strong chemical stability, resistant to weak acids and alkalis; in addition, it also has good adhesiveness, emulsifying property, and antistatic property, which are widely used in textile, papermaking, construction, medicine, and other fields as adhesives, emulsifiers, coating materials, etc.Technical Dada

PVA is widely used in the construction industry. With its excellent adhesiveness, film-forming property and water resistance, it can serve as the core component of adhesives such as tile glue and wallpaper glue to enhance the bonding firmness between materials. It is used in wall coatings and waterproof coatings to improve the scrub resistance, weather resistance and waterproof performance of the coating. Added to putty and mortar, it can improve construction performance and enhance water retention and crack resistance. It can also be made into water-soluble films for chemical packaging or used as a moisture-proof isolation layer in wet areas. In addition, adding a small amount to concrete can improve its workability and crack resistance, helping to enhance the quality and durability of construction projects.
PVA plays a key role in the textile industry. With good film-forming and adhesive properties, it serves as an important sizing agent for warp yarns, effectively improving yarn wear resistance and strength to reduce breakage during weaving. As a fabric finishing agent, it can improve the hand feel, luster and wrinkle resistance of fabrics. In the printing and dyeing process, PVA can be used as a printing paste to ensure clear patterns and improve color paste stability. Besides, it is also applied to prepare functional textile materials, endowing fabrics with special properties to enhance product quality and added value.
