Polyvinyl alkol (PVA) Wanwei
Polyvinyl alkol (PVA) polîmerek ku di avê de çareser nabe, bi gelemperî felqek spî an sivik zer, felq, granular an tozek hişk e.Performansa wê di navbera plastîk û gomê de ye.Ew xwedan girêdanek baş, şiyana çêkirina fîlimê, îzolasyon, berxwedana rûnê, berxwedana hejandinê û milkê astengiya gazê, hwd.
Bikaranîna hilberê
Polyvinyl alkol (PVA) gelek karanîn hene.
Di pîşesazîya tekstîlê de, ew wekî slurya warpê, kargêrê qedandina tekstîlê, û zeliqandî yên qumaşên ne-vekirî tê bikar anîn.
Di pîşesaziya avahîsaziyê de, ew wekî pêvekên çîmentoyê, zeliqandî yên plakaya çêjkirinê, û çîpên avahiyê tê bikar anîn.
Di pîşesaziya kîmyewî de, ew stabîlker û belavkerên semulsîyonê têne bikar anîn.
Di pîşesazîya kaxezçêkirinê de, wekî adhesive tê bikaranîn.
Wekî din, Ew dikare di pîşesaziya kozmetîkê, çandinî, pîşesaziya derman, hwd de were bikar anîn.
