I-PVC yenye yeplastiki ezisetyenziswa kakhulu kwicandelo lemveliso. I-Plasticol, inkampani yase-Itali ekufutshane neVarese ibisenza ii-granules ze-PVC kangangeminyaka engaphezu kwama-50 ngoku kwaye amava aqokelelweyo kule minyaka idlulileyo avumele ishishini ukuba lifumane ulwazi olunzulu kangangokuba ngoku sinokulusebenzisa ukwanelisa zonke izicelo zabathengi abanikezela ngeemveliso ezintsha nezithembekileyo.
Inyani yokuba i-PVC isetyenziswa kakhulu ekuveliseni izinto ezahlukeneyo ibonisa indlela iimpawu zayo zangaphakathi eziluncedo kakhulu kwaye zikhethekile ngayo. Masiqale sithethe ngokuqina kwe-PVC: le nto iqinile kakhulu ukuba icocekile kodwa iba bhetyebhetye xa ixutywe nezinye izinto. Olu phawu lwahlukileyo lwenza i-PVC ifaneleke ekuveliseni iimveliso ezisetyenziswa kwiindawo ezahlukeneyo, ukusuka kweyokwakha ukuya kweyemoto.
Nangona kunjalo, ayizizo zonke iimpawu zale nto eziluncedo. Ubushushu bokunyibilika kwale polima buphantsi kakhulu, nto leyo eyenza i-PVC ingafanelekanga kwiindawo apho amaqondo obushushu aphezulu kakhulu anokufikelelwa khona.
Ngaphezu koko, iingozi zinokubangelwa kukuba, ukuba ishushu kakhulu, i-PVC ikhupha iimolekyuli ze-chlorine njenge-hydrochloric acid okanye i-dioxin. Ukudibana nale nto kunokubangela iingxaki zempilo ezingenakulungiswa.
Ukuze i-polymer ihambelane nemveliso yayo yemizi-mveliso, ixutywa nezibambisi-ndlela, iiplastiki, imibala, kunye nezinto zokuthambisa ezinceda kwinkqubo yokwenziwa kwayo kunye nokwenza i-PVC ithambeke ngakumbi kwaye ingagugi kakhulu.
Ngokusekelwe kwiimpawu zayo kunye nobungozi bayo, ii-granules ze-PVC kufuneka ziveliswe kwizityalo ezikhethekileyo. I-Plasticol inomgca wemveliso ozinikele kuphela kule nto yeplastiki.
Inqanaba lokuqala lokwenziwa kwee-granules ze-PVC liquka ukwenziwa kweetyhubhu ezinde zezinto ezenziwe ngesityalo esikhethekileyo sokukhupha. Inyathelo elilandelayo liquka ukusika iplastiki ibe ziintsimbi ezincinci kakhulu. Inkqubo ilula kakhulu, kodwa kubaluleke kakhulu ukuba uqaphele xa uphatha izinto, uthatha amanyathelo asisiseko anokwenza kube nzima ngakumbi.
