I-PVA glue isifinyezo se-Polyvinyl acetate.Ukubonakala kuyimpushana emhlophe.Iwuhlobo lwe-polymer encibilika emanzini enezinhlobonhlobo zokusetshenziswa.Ukusebenza kwayo kuphakathi kwepulasitiki nerabha.Ukusetshenziswa kwayo kungahlukaniswa ngokusetshenziswa okubili okukhulu: i-fiber kanye ne-non-fiber.Ngenxa yokuthi i-PVA inokunamathela okuqinile okuyingqayizivele, ukuguquguquka kwefilimu, ubushelelezi, ukumelana nowoyela, ukumelana ne-solvent, i-colloid evikelayo, isithiyo segesi, ukumelana nokuhubhuka nokumelana namanzi ngokwelashwa okukhethekile, ayisetshenziswa nje kuphela njenge-fiber eluhlaza , Ibuye isetshenziswe kabanzi ukukhiqizwa kwezingubo zokugqoka, izinto zokunamathisela, ama-ejenti okucubungula amaphepha, ama-emulsifiers, ama-dispersants, amafilimu neminye imikhiqizo, ngezicelo ezimboza izindwangu, ukudla, imithi, ukwakhiwa, ukucubungula izinkuni, ukwenza iphepha, ukuphrinta, ezolimo, insimbi, imboni yamakhemikhali e-Polymer nezinye izimboni.
Uma iqhathaniswa nezinamatheliso ezifanayo emakethe, ayinazo izithako ezinobuthi njenge-formaldehyde (kusetshenziswa i-urea-formaldehyde resin eguquliwe noma i-melamine resin noma i-phenolic resin encibilika emanzini engafinyelela ukuvikelwa kwemvelo E2 noma ngaphezulu. kungaba okunye Nciphisa okuqukethwe kwamahhala kwe-formaldehyde komkhiqizo), akukho ukungcola endaweni yokukhiqiza nokusebenzisa, izindleko eziphansi, inqubo elula, umphumela omuhle wokubopha, ukomisa ngokushesha kanye nesivinini sokuqina.Isetshenziselwa ukukhiqizwa kwephaneli esekwe ngokhuni ngaphandle kokucindezela okushisayo futhi kunezinzuzo ezibalulekile ekongeni amandla.
Amakhasimende amaningi manje asebenzisa i-PVA white latex ukwenza ama-slime.Lokhu kungenye yezindlela ezinhle zokusebenzisa i-PVA glue.Kwamanye amazwe eYurophu naseMelika, abantu abaningi banikeza izingane zabo imfundo yamabanga aphansi.Impahla yayo ayinabo ubuthi futhi inobungani bemvelo, ngakho-ke asikho isidingo sokukhathazeka ngokuthi iglue izolimaza izingane.
