Iplastiki yePVC ibhekisa kwi-PVC edibeneyo kwishishini lemichiza.Igama lesiNgesi: i-polyvinyl chloride, isishunqulelo sesiNgesi: PVC.Le yeyona ntsingiselo isetyenziswa kakhulu yePVC.
Umbala wayo wendalo utyheli ngokuguquguqukayo kwaye uyakhazimla.I-transparency ingcono kune-polyethylene kunye ne-polypropylene, kwaye imbi ngakumbi kune-polystyrene.Ngokuxhomekeke kubungakanani bezongezo, zinokwahlulwa zibe yiPVC ethambileyo nenzima.Iimveliso ezithambileyo zithambile kwaye ziqinile, kwaye ziziva zincangathi.Ubunzima beemveliso ezinzima buphezulu kune-polyethylene ephantsi, kodwa iphantsi kune-polypropylene, kwaye kuya kubakho i-albinism kwiindawo zokugoba.Iimveliso eziqhelekileyo: iipleyiti, iipayipi, ii-sole, iithoyi, iingcango kunye neefestile, izikhumba zocingo, izinto zokubhala, njl.
Imbaleki kunye nesango: onke amasango aqhelekileyo anokusetyenziswa.Ukuba ukucubungula iindawo ezincinci, kukulungele ukusebenzisa isango lohlobo lwenaliti okanye isango eliphantsi kwamanzi;Kwiindawo ezityebileyo, kungcono ukusebenzisa amasango amile okwefeni.Ubuncinane bedayamitha yohlobo lwesango lenaliti okanye isango eliphantsi kwamanzi liya kuba yi-1mm;Ubukhulu besango elimilise okwefeni abuyi kuba ngaphantsi kwe-1mm.
Ukusetyenziswa okuqhelekileyo: imibhobho yonikezelo lwamanzi, imibhobho yendlu, iibhodi zodonga zendlu, amaqokobhe omatshini woshishino, ukupakishwa kweemveliso zombane, izixhobo zonyango, ukupakishwa kokutya, njl.
Iipropati zeMichiza kunye nezomzimba zePVC engqongqo yePVC yenye yezona zinto zisetyenziswa kakhulu kwiplastiki.Imathiriyeli yePVC yimathiriyeli ye-amorphous.I-stabilizers, i-lubricants, i-axiliary processing agents, ii-pigments, ii-agent zokuqinisa kunye nezinye izongezo zihlala zongezwa kwizinto ze-PVC ekusebenziseni okusebenzayo.
Izinto zePVC zinokutsha, ukomelela okuphezulu, ukumelana nemozulu kunye nokuzinza okuhle kakhulu kwejometri.I-PVC inokumelana okunamandla kwi-oxidants, i-reductants kunye ne-acids ezomeleleyo.Nangona kunjalo, inokugqwaliswa ziiasidi ze-oxidizing ezigxininisiweyo ezifana ne-sulfuric acid egxininisiweyo kunye ne-nitric acid, kwaye ayifanelekanga kumathuba okudibana ne-hydrocarbons enevumba elimnandi kunye ne-chlorinated hydrocarbons.
Ukushisa okunyibilikayo kwePVC ngexesha lokucubungula kuyinkqubo ebaluleke kakhulu ipharamitha.Ukuba le parameter ayifanelekanga, iya kukhokelela kwingxaki yokubola kwezinto.Iimpawu zokuhamba kwePVC zimbi kakhulu, kwaye uluhlu lwenkqubo yalo lumxinwa kakhulu.Ngokukodwa, izixhobo zePVC ezinobunzima obukhulu bemolekyuli zinzima ngakumbi ukuqhubekeka (ezi zinto zidla ngokufuna ukongeza i-lubricant ukuphucula iimpawu zokuhamba), ngoko ke izixhobo zePVC ezinobunzima obuncinci bemolekyuli zihlala zisetyenziswa.Ukucutheka kwePVC kuphantsi kakhulu, ngokubanzi 0.2 ~ 0.6%.
