Polyvinyl cawv (PVA) Wanwei
Polyvinyl cawv (PVA) yog cov tsis muaj kuab paug dej-soluble polymer, feem ntau yog dawb los yog me ntsis daj floccule, flake, granular los yog hmoov.Nws qhov kev ua tau zoo yog nruab nrab ntawm cov yas thiab roj hmab.Nws muaj adhesion zoo, zaj duab xis-tsim muaj peev xwm, rwb thaiv tsev, roj tsis kam, abrasion tsis kam thiab roj barrier khoom, thiab lwm yam.
Khoom siv
Polyvinyl cawv (PVA) muaj ntau yam kev siv.
Hauv kev lag luam textile, nws yog siv los ua warp slurry, textile finishing agent, thiab adhesives ntawm non-woven fabrics.
Hauv kev tsim kho kev lag luam, nws yog siv los ua cov cement additives, molding phaj adhesives, thiab cov kua nplaum hauv tsev.
