Imiphongolo ye-flat twin screw idlala indima ebalulekile ekukhiqizeni amapayipi namaphrofayili e-PVC.Indlela esebenza ngayo kule mikhakha emibili ibhalwe ngezansi: Ukwenza ipulasitiki nokuxutshwa kwezinto: Umphongolo wesikulufu uncibilika ngokugcwele futhi uxube inhlaka ye-PVC nezinye izithasiselo ngesikulufu esijikelezayo nendawo yokushisisa.Lokhu kwenza impahla ye-PVC ithambe futhi kulula ukuyicubungula nokuma.Ukubunjwa kwe-Extrusion: Ngaphansi kwesenzo somphongolo wesikulufu, into encibilikisiwe ye-PVC ikhishwa ngedayizi ukuze kwakheke umkhiqizo oneshubhu noma omise okwephrofayili.
Ukuklama nokulungiswa komgqomo wesikulufa kwenza ukukhiqizwa kwamapayipi namaphrofayili wobumo nobukhulu obuhlukene.Ukupholisa nokuqiniswa: Ngemva kokukhishwa, ipayipi noma iphrofayela ipholisa ngokushesha ngesistimu yokupholisa ukuze kuqiniswe okokusebenza nokugcina ukuma kwayo.Ukusika Nokunquma: Sebenzisa amathuluzi afana nemishini yokusika nemishini yokunquma ukuze ulungise usayizi futhi uqedele inqubo yamapayipi namaphrofayili akhishiwe.Ngamafuphi, i-flat twin-screw barrel idlala indima ebalulekile ekukhiqizeni amapayipi e-PVC namaphrofayili, eqaphela i-plasticization, ukuxuba, ukubunjwa kwe-extrusion kanye nokucubungula okulandelayo kwezinto, ukuqinisekisa ikhwalithi nokusebenza komkhiqizo wokugcina.
