U-Polyvinyl chloride — olungumthetho omncane okanye u-PVC — yi-plastic elingezantsi esiyaziyo kakhulu emibhalo yamalayithi angaphambili. U-PVC yi-material engcono esifundiswa ngaso sengxenyeni kusuka toyesi kwi-pipes. Ngisho inkathi le? Ngiyafuna ukwazi ukuthi u-PVC uyathintelekiswa ngingapi? Ningakho kudinga ukwazi ukuthi u-PVC uyathintelekiswa, ingxenye yesilondolozi yokuthiwa, umthetho omusha, imibono yomarket, noma amagama asihlukanisiwe ngamalaba kunye nokuthuthukisa yobudlelwano njengezinto ezivunyelweyo kule-process.
Ukubuyisela i-resin ngokuthi ikhiwe ipolimeri yiniyo le nto ephambili kwisebenza le-PVC. I-resin iyiphulakiso yemibhulichisi ethunyelwe amasimu ane-vinyl chloride. Lemibhulichisi akhiwa nge-chemicals esinye ukuvula umlilo. Umliwyo wakhiwa, uwushelelwa kunye nokubuyiselwa ngokupolimeri. Ipolimeri yi-series elincane lomolozi olungabizwi njengalokhu olungayiphihlisa kunye nokuhlola ku-PVC ngokushesha kunye nokuchasene. Ngemuva kokubuyisela ipolimeri, u-extrusion kunye no-injection-molding siyangena amakhono amabili okungavalelwe ukuba zikhethwe ngokuphezulu kuzo zinto eziningi.
Ngokushesha lokusenziwa kwegama lasePVC, ukusetha kwesilima kunokukhombisa isikhathi. Umphumela omncane wokuqala kukuthi usethelo wesilimi somncane sokuthiwa. Okunye lezilimi zingaziphatha amadlozi nokulandelana nokulandelana ngeemoto nokulandelana nezinye izilimi. Ngokuhlukanisiwa kwezi zinto, kunezinhlobo zokuthiwa zePVC ezizihlanganisiwe nokusetshenziswa kweenergy yenkululeko.
Kunezakalelayo eziningi kwiPVC manufacturing ngezinyathelo eziqondileyo ngalokusha ukuthi kube uyahlukaniselelanga nokuthi kube kuhluke kakhulu phakathi kwesikhathi. Ukusukelwa okwesipho esingekho sisho amacatalizatha amahluke amaphambili nokulawula amakhemikhali amanye amaphambili apho iproduct PVC iye ukuze usebenze ngesicatshulwa esidingeni kunye nezinto ezinamandla. Ngaphandle, umthetho wokugcina olusemthethweni wakhiwo ukuphinda ukusetshenziswa kwamaphephandaba wePVC, okungakuvumela ukuba amanani akhona emagunyeni. Lezi zinto zithathelanga izinto zomoya kwePVC ukusetshenziswa ngendlela enhle yobubanzi.
I-PVC yi-material enkulu yokugcina, eyinhloko yesikhatsi esisodwa sesihlukanisa. Kunesikhatsi esisodwa sekhethekileyo se-PVC esiqhutywayo ngamaxesha edluleyo ngokwezifundo ezilimi neZhayinike, neMereka Umdondo kunye neJermani. Ngenxa yalokusha lokuhlukanisa lesikhatsi sesisodwa sesi-PVC, abasebenzi babenza imibono emabini wakhiwo ukuyimfanelo lokuhlukanisa ngokuthi bengxoxe ngezinto ezinhlane zokuthi zisetshenziswa ngendlela enhle yobubanzi, ukusetshenziswa kwezinhlelo kunye nokuhlukanisa kwezindawo.
Ama-manufacturer ePVC akhawuzi kakhulu ngokuhlala ngenkinga yakhe yokuthuthukisa, kodwa basebenziswe baye abantu babo bese. Lolu hlobo lokusebenza kuhluke izindlela ezahlukene zokubeka amagama asebenzi ukuthi uPVC ubekwe ngempumelelo, umva wemvula nokulandelana nomoya emasayensi ethiweni lase-production neziqinisekiso zokuthuthukisa zibe olandelayo ukuvimba iizikhatsi. Kube kudinga ama-manufacturer wePVC ukufaka indlela yokuhlala kakhulu kwesibhedlela sokusebenzela kunye nokuthuthukisa yomsebenzi wesilondolozi.
