Toaka polyvinyl (PVA) Wanwei
Ny toaka polyvinyl (PVA) dia polymère tsy mandoto rano, matetika fotsy na mavo mavo, flake, granular na vovoka matevina.Ny fahombiazany dia eo anelanelan'ny plastika sy ny fingotra.Izy io dia manana adhesion tsara, fahaiza-mamorona sarimihetsika, insulation, fanoherana solika, fanoherana abrasion ary fananana sakana entona, sns.
Fampiasana vokatra
Ny alikaola polyvinyl (PVA) dia manana fampiasa isan-karazany.
Ao amin'ny indostrian'ny lamba dia ampiasaina ho toy ny slurry warp, mpanamboatra lamba vita amin'ny lamba, ary adhesive amin'ny lamba tsy voatenona.
Ao amin'ny indostrian'ny fanorenana dia ampiasaina ho additives simenitra, adhesives fametahana takelaka, ary lakaoly fananganana.
Ao amin'ny indostrian'ny simika, dia ampiasaina ny semulsion stabilizer sy dispersants.
Ao amin'ny indostrian'ny fanamboarana taratasy dia ampiasaina ho adhesive izy io.
Ankoatra izany, azo ampiasaina amin'ny indostrian'ny kosmetika, fambolena, indostrian'ny pharmaceutika, sns.
