Building Grade Pva Powder Para sa Malagkit
A. Ang may tubig na solusyon ng polyvinyl alcohol ay may malakas na pagdirikit sa mga materyales na naglalaman ng selulusa (tulad ng papel, tela, kahoy, atbp.), at may mga pakinabang ng kaligtasan at hindi nakakalason. Maaari itong magamit para sa laminating cardboard, bonding corrugated cardboard at office glue. Ang mga kraft paper bag para sa pag-iimpake ng mabibigat na bagay tulad ng semento, pataba at butil ay gumagamit din ng PVA bilang pandikit.
B. Ang polyvinyl alcohol aqueous solution (sa pamamagitan ng pagdaragdag ng naaangkop na mga filler at additives) ay malawakang ginagamit upang maghanda ng mga pandikit para sa pag-print at pagbubuklod, mga tubo ng papel, mga karton at iba pang mga produktong papel.
C. sa ilalim ng pagkilos ng acid catalysis, ang polyvinyl alcohol ay pinalapot ng formaldehyde, butyraldehyde, glyoxal o iba pang aldehydes upang makabuo ng polyvinyl acetals (tulad ng PVAF at PVB) na may mas malakas na water resistance, adhesion at mechanical strength, na malawakang ginagamit sa construction, coatings, adhesives, safety glass interlayer at iba pang field.

Product Application
The aqueous solution of polyvinyl alcohol resin (PVA) has good film-forming and emulsifying properties. It can be used as a protective colloid for polymer emulsification and suspension polymerization. Polyvinyl alcohol can be used in textile pulp, Winnie fiber, coating agent for papermaking, building materials, adhesives, PVA films, PVB raw materials, food and medicine, etc. PVA can also be used as soil improver, polymerization suspending agent, emulsifier, quenching agent, etc. In addition, with the continuous development and improvement of PVA's performance, its application is still expanding.
