PVC ni imwe muri plastiki zikoreshwa cyane murwego rwinganda. Plasticol, isosiyete yo mu Butaliyani iherereye hafi ya Varese imaze imyaka irenga 50 ikora granules ya PVC kandi uburambe bwakusanyirijwe mu myaka yashize bwatumye ubucuruzi bwunguka ubumenyi bwimbitse kuburyo dushobora gukoresha ubu kugirango duhaze abakiriya bose 'gusaba gutanga ibicuruzwa bishya kandi byizewe.
Kuba PVC ikoreshwa cyane mugukora ibintu byinshi bitandukanye byerekana uburyo ibiranga imbere bifite akamaro kanini kandi bidasanzwe. Reka dutangire tuvuge ubukana bwa PVC: ibikoresho birakomeye cyane niba byera ariko bigahinduka iyo bivanze nibindi bintu. Iyi mico itandukanye ituma PVC ibereye gukora ibicuruzwa bikoreshwa mubice bitandukanye, kuva inyubako imwe kugeza kumodoka.
Ariko, ntabwo buri kintu cyihariye cyibintu cyoroshye. Ubushyuhe bwo gushonga bwiyi polymer buri hasi cyane, bigatuma PVC idakwiriye kubidukikije aho ubushyuhe bwo hejuru bushobora kugerwaho.
Byongeye kandi, ingaruka zishobora guturuka ku kuba, iyo ubushyuhe bwinshi, PVC irekura molekile ya chlorine nka aside hydrochloric cyangwa dioxyde. Guhura niyi ngingo bishobora gutera ibibazo byubuzima bidasubirwaho.
Kugira ngo polymer ihuze n’umusaruro w’inganda, ivangwa na stabilisateur, plasitike, amabara, hamwe n’amavuta bifasha mubikorwa byo gukora kimwe no gukora PVC yoroshye kandi idakunda kwambara no kurira.
Ukurikije ibiyiranga n’akaga kayo, granules ya PVC igomba kubyazwa umusaruro mubihingwa kabuhariwe. Plastike ifite umurongo wo kubyaza umusaruro gusa ibi bikoresho bya plastiki.
Icyiciro cya mbere cyo gukora granules ya PVC kigizwe no gukora imiyoboro miremire y'ibikoresho ikozwe mu ruganda rwihariye. Intambwe ikurikira igizwe no guca plastike mumasaro mato rwose. Inzira mubyukuri iroroshye, ariko ni ngombwa cyane gukoresha ubwitonzi mugihe ukoresha ibikoresho, ufata ingamba zifatika zishobora gutuma bigorana.
