Lapho amaphrofayili egwebu le-PVC ethulwa ngawo-1970, abizwa ngokuthi “ukhuni lwesikhathi esizayo,” futhi ukwakheka kwawo kwamakhemikhali kuyi-polyvinyl chloride.Ngenxa yokusetshenziswa kabanzi kwemikhiqizo eqinile ye-PVC enegwebu eliphansi, ingathatha indawo cishe yonke imikhiqizo eyenziwe ngokhuni.
Eminyakeni yamuva nje, ubuchwepheshe babakhiqizi bephrofayili yegwebu le-PVC nabo buye bathuthuka ngokushesha, okuvumela imikhiqizo eqinile ye-PVC yegwebu ukuthi ithuthukiswe emkhakheni wezinto zokwakha nezokuhlobisa, kanye nokwakhiwa kwempahla yefenisha.
Ngokungeza isigcwalisi esihlukile emikhiqizweni yegwebu le-PVC, izici ezahlukahlukene zinikezwa imikhiqizo eqinile yegwebu le-PVC.Yandisa ububanzi bokusetshenziswa komkhiqizo ekusetshenzisweni okuhlukile kwezinto zokwakha ezihlukahlukene kanye nezinto zokwakha zokuhlobisa.Ngesikhathi esifanayo imikhiqizo eqinile ye-PVC yegwebu inezindawo ezinhle zokuhlobisa ezingaphezulu.
Izinto zephrofayili yegwebu le-PVC evikela umswakama, i-anti-corrosion, i-flame retardant, engenabuthi, futhi engenaphunga. Lolu hlobo lomkhiqizo lungathuthukisa ngempumelelo indawo yokuhlala, futhi inqubo yegwebu le-PVC manje isisetshenziswa ngokuyinhloko igwebu eliqinile le-PVC kanye negwebu le-crust. ibhodi, kanye namanye amaphrofayili okuhlobisa enziwe ngegwebu le-PVC, ukwenza isikali sobuchwepheshe bomkhiqizo.Ukusetshenziswa kocwaningo kuya ngokuya kuvame emikhakheni yokwakha, ukupakisha, ifenisha, nezinye izindawo.
Ingaphezulu lebhodi legwebu le-PVC lingafuthwa, elingagwema ukushintshwa kombala ongaphezulu futhi linenzuzo yobulukhuni bokulwa nokuklwebheka.Bese kuba nendlela yethu evamile yokukhiqiza ukucubungula, ekunamekelweni okungaphezulu ku-crystal plate, ukucubungula okujwayelekile kuzozenzakalela kakhulu umshini wokuvala onqenqemeni, futhi umshini wokuvala uphawu othomathikhi onqenqemeni uzothinta uhlukaniswe ngesakhiwo sohlobo lwe-roller kanye nohlobo lwe-crawler yesibili, kodwa uma kungenjalo. sebenzisa igwebu elingenalutho lapho kunconywa ukuthi usebenzise futhi unamathisele indawo ebonakalayo inombala ofanayo, gwema ukunamathisela kwephepha ekuthuthukisweni kokuncipha lapho ubonisa ukuthi ukwakheka kunomehluko osobala wombala.
