I-PVC ingenye yepulasitiki esetshenziswa kakhulu emkhakheni wemboni.I-Plasticol, inkampani yase-Italy eseduze ne-Varese isikhiqize ama-PVC granules iminyaka engaphezu kwe-50 manje futhi ulwazi oluqoqwe phakathi neminyaka luvumela ibhizinisi ukuthi lithole izinga elijulile lolwazi kangangokuthi manje sesingakwazi ukulisebenzisa ukwanelisa wonke amaklayenti. ' izicelo ezihlinzeka ngemikhiqizo emisha nethembekile.
Iqiniso lokuthi i-PVC isetshenziswa kabanzi ukukhiqiza izinto eziningi ezahlukahlukene likhombisa ukuthi izici zayo ezingaphakathi ziwusizo kakhulu futhi zikhethekile.Ake siqale ukukhuluma ngokuqina kwe-PVC: impahla iqinile kakhulu uma ihlanzekile kodwa iyashintshashintsha uma ihlanganiswe nezinye izinto.Le mfanelo ehlukile yenza i-PVC ifanelekele ukukhiqizwa kwemikhiqizo esetshenziswa emikhakheni ehlukene, kusukela esakhiweni kuya kweyezimoto.
Kodwa-ke, akuyona into engavamile ngayinye yento efanelekile.Izinga lokushisa elincibilikayo lale polymer liphansi kakhulu, okwenza i-PVC ingafaneleki kulezo zindawo lapho amazinga okushisa aphakeme kakhulu angafinyelelwa khona.
Ngaphezu kwalokho, izingozi zingavela eqinisweni lokuthi, uma ishisa ngokweqile, i-PVC ikhipha ama-molecule e-chlorine njenge-hydrochloric acid noma i-dioxin.Ukuhlangana nale nto kungabangela izinkinga zempilo ezingalungiseki.
Ukwenza i-polymer ihambisane nokukhiqizwa kwayo ezimbonini, ixubene nezinza, amapulasitiki, ama-colorants, kanye nezinto zokugcoba ezisiza enqubweni yokukhiqiza kanye nokwenza i-PVC ithambile futhi ingabi lula ukuguga.
Ngokusekelwe ezicini zayo kanye nokuba yingozi kwayo, ama-PVC granules kufanele akhiqizwe ezitshalweni ezikhethekile.I-Plasticol inomugqa wokukhiqiza onikezelwe kuphela kule nto yepulasitiki.
Isigaba sokuqala sokwenziwa kwama-PVC granules sihlanganisa ukwakhiwa kwamashubhu amade ezinto ezenziwe ngesitshalo esikhethekile se-extrusion.Isinyathelo esilandelayo sihlanganisa ukusika ipulasitiki ngobuhlalu obuncane ngempela.Inqubo empeleni ilula, kodwa kubaluleke kakhulu ukusebenzisa ukuqapha lapho uphatha indaba, uthatha izinyathelo zokuphepha eziyisisekelo ezingenza kube nzima nakakhulu.
