Polyvinyl doro CAS:25213-24-5

Polyvinyl alcohol (PVA) inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana nekuda kwehunhu hwayo hunoshamisa. Muindasitiri yekunamatira, inoshanda sechinhu chakakosha mumhando dzakasiyana-siyana, ichipa hunhu hwakasimba hwekubatanidza mukushandiswa kubva kumaglue ehuni kusvika kumaglue epepa. Kugona kwayo kunyungudika mumvura uye kugadzira mafirimu kunoita kuti ive yakakosha mukugadzira zvinhu zvekurongedza zvinonyungudika mumvura, mabhegi ekuwachira, uye zvigadzirwa zvemachira, zvichipa mhinduro dzezvinodiwa zvekurongedza zvine hushamwari uye zvinonyungudika. Muindasitiri yemachira, PVA inoshandiswa zvakanyanya semushonga wekuwedzera saizi yewarp kuti iwedzere maitiro ekuruka, ichipa simba uye kuchinjika kumashinda. Pamusoro pezvo, inoshanda semushonga wekudzivirira mukugadzira macopolymers akavakirwa pavinyl acetate uye semubati mukudhinda pigment. Uyezve, PVA inoita basa rakakosha muindasitiri yemapepa, uko inoshandiswa semushonga wekuwedzera saizi pamusoro kuti ivandudze simba repepa, kudhindwa, uye kunyudzwa kweinki. Maindasitiri emishonga nezvekudya anoshandisa PVA mukugadzira makapisi, semushonga wekuvhara mapiritsi, uye mukugadzira mafirimu anodyiwa ekurongedza chikafu. Kuenderana kwayo nezvinhu zvipenyu uye kusaita chepfu kunoitawo kuti PVA ive chinhu chinokosha mukurapa, kusanganisira sechinhu chinoshandiswa mukugadzira maronda, masisitimu ekutumira mishonga, uye mascaffolds ekugadzira matishu. Kazhinji, mashandisirwo akasiyana-siyana ePVA anoratidza kukosha kwayo sepolymer inoshanda zvakasiyana-siyana muzvikamu zvakasiyana-siyana zvemaindasitiri nemabhizimisi.
