Whakaehunga Whakapumau me te Binder
Ka taea te whakamahi whanui i te PVA hei colloid whakamarumaru, hei whakakaha ranei mo te polymerization whakaehunga o te acetate vinyl (VAc) me te VAc/acrylate ranei.e whai ake nei nga ahuatanga: te pai 0 te whakapiri; te piki ake o te taiki tuatahi me te tere whakamaroke i te wa e whakamahia ana me te whakakii;te ātete pai ki te hinu;kiriata tino.
I roto i te hanga muka
E rua nga tono nui o te PVA ka whakamahia hei whangai vinylon me te kaihoko rahi mo te kakano.Hei rauemi mata o te muka vinylon, he pai ake te kaha o te kaha, te whakauru makuku, te aukati abrasion, te aukati o te ra, te aukati waikura me te tae ma.Ka taea hoki te miro ki te miro, te wūru me te muka viscose, te miro noa ranei ki a ia ano. Hei kaihoko rahi mo te pueru, E kore e pirau, e kino ranei ki te piri pai ki te miro, hemp, polyester me te muka viscose.
Kua kitea e te Pulp & PaperPVA te whakamahinga whanui mo te maimoatanga o te mata pepa na te mea he pai te whakapiri me te mararatanga, a, kaore e pa ki nga taonga o etahi atu here e whakamahia ana i te whakakotahitanga.Ko nga painga o te PVA ma te whakamahi: Te kaha o te mata (ka taea te tuhi) ；Te kaha ki te tuaka-Z (te kaha o roto o te pepa); te atete whakakopa； Te atete abrasive; Te pai ake o te maeneene; Te pai ake o te kanapa o te mata; Kua piki ake te atete ki te hinu me te whakarewa (taonga arai).
Kiriata
Ka taea te whakamahi i te PVA ki te whakaputa i te kiriata wairewa wai me te kiriata wai-atete. Kei te waatea te PVA i roto i nga hua i hangaia e whakaatu ana i nga ahuatanga o te PVA, ara, te kaha o te kaha, te aukati ki te whakarewa pararopi me te kaha o te hau. ahumahi mōkihi, ehara i te mea mo te pueru anake, engari mo nga matū, kai, matū o ia ra, matū ahuwhenua, waikano, aha atu.
Whakapumau Marara
Ko te PVA, he tino pai ki te whakamarumaru colloid, he pai ake te mahi o te mata, he maha nga wa ka whakamahia hei whakamaarama whakamararatanga mo te polymerization whakatārewatanga o te vinyl chloride monomer (VCM).Ko te mahi o te kapia PVC ka taea te tino arotau ma te kowhiri i te karaehe PVA e tika ana me te tohu polymerization me te hydrolysis.
Neke atu i te 1000m2 te whare putunga mo te PVA kia mau tonu te toha me te utu whakataetae i nga wa katoa.
