PVA yera

PVA kole ni impfunyapfunyo ya acetate ya Polyvinyl.Kugaragara ni ifu yera.Nubwoko bwamazi ashonga polymer hamwe nuburyo bwinshi bwo gukoresha.Imikorere yacyo iri hagati ya plastiki na reberi.Imikoreshereze yacyo irashobora kugabanywamo ibice bibiri byingenzi: fibre na fibre.Kuberako PVA ifite imbaraga zidasanzwe zifatika, guhuza firime, koroshya, kurwanya amavuta, kurwanya solvent, kurinda colloid, inzitizi ya gaze, kurwanya abrasion no kurwanya amazi hamwe nubuvuzi bwihariye, ntabwo ikoreshwa nkibikoresho bya fibre gusa, Irakoreshwa cyane muri umusaruro wimyenda, ibifatika, ibikoresho byo gutunganya impapuro, emulisiferi, ikwirakwiza, firime nibindi bicuruzwa, hamwe nibisabwa bikubiyemo imyenda, ibiryo, ubuvuzi, ubwubatsi, gutunganya ibiti, gukora impapuro, gucapa, ubuhinzi, ibyuma, inganda za chimique Polymer nizindi nganda.
Ugereranije n’ibifatika bisa ku isoko, ntabwo birimo ibintu byuburozi nka formaldehyde (ukoresheje resine ya urea-formaldehyde ya resin cyangwa melamine resin cyangwa amazi ya elegitoronike ya fenolike ishobora kugera ku bidukikije E2 cyangwa irenga. Nyuma yo kongeramo imiti ikiza na gypsumu, Birashobora gukomeza Kugabanya ibiciro bya fordehide yubusa kubicuruzwa), nta kwanduza umusaruro no gukoresha ibidukikije, igiciro gito, inzira yoroshye, ingaruka nziza yo guhuza, gukama vuba no kwihuta.Ikoreshwa mugukora ibiti bishingiye kumashanyarazi nta gukanda bishyushye kandi bifite inyungu zikomeye mukuzigama ingufu.
Abakiriya benshi ubu bakoresha PVA yera latex kugirango bakore slime.Iyi nayo ni imwe mu mikoreshereze ikomeye ya PVA kole.Mu bihugu bimwe na bimwe byo mu Burayi no muri Amerika, abantu benshi baha abana babo icyiciro cyuzuye nkuburezi bwibanze.Ibikoresho byayo ntabwo ari uburozi kandi byangiza ibidukikije, kubwibyo rero nta mpamvu yo guhangayikishwa n’uko kole izangiza abana.
