Umbhobho wokujija umbhobho luhlobo lwezixhobo ezisetyenziselwa ngokukodwa ukusetyenzwa kwezixhobo zemibhobho, ezisetyenziselwa ukuveliswa kwemibhobho yeplastiki.
Ezi zilandelayo zezinye izicelo zemibhobho ye-screw tyhubhu: Imibhobho ye-PVC: Imibhobho ye-screw ingasetyenziselwa ukucubungula imibhobho eyenziwe nge-polyvinyl chloride (PVC), njengemibhobho yokuhambisa amanzi, imibhobho yokuhambisa amanzi, iingcingo kunye nemibhobho yokucheba intambo, njl.
Umbhobho we-PE: umbhobho we-screw barrel ungasetyenziselwa ukucubungula imibhobho eyenziwe nge-polyethylene (PE), njengemibhobho yokuhambisa amanzi, imibhobho yegesi, imibhobho yonxibelelwano ye-cable sheath, njl. ngombhobho wokujija umbhobho, onjengemibhobho yeekhemikhali, imibhobho yokungenisa umoya, njl.
Umbhobho wePPR: Umbhobho we-screw barrel ungasetyenziselwa ukuvelisa umbhobho we-polypropylene thermal composite pipe (PPR pipe), ehlala isetyenziselwa ukwakha unikezelo lwamanzi kunye neenkqubo zokufudumeza.
Umbhobho we-ABS: umbhobho we-screw barrel unokuphinda usebenze imibhobho eyenziwe nge-acrylonitrile-butadiene-styrene copolymer (ABS), ehlala isetyenziswa kwimibhobho yezoshishino, imibhobho yekhemikhali, njl.
Imibhobho yePC: Izinto zePolycarbonate (PC) nazo zinokucutshungulwa zibe yimibhobho ngemibhobho ye-screw barrel, njengemibhobho yokunkcenkceshela, imibhobho eqinisiweyo ye-FRP, njl.
Isishwankathelo, imibhobho ye-screw ye-screw isetyenziswa kakhulu ekuveliseni imibhobho yeplastiki, ekwazi ukucubungula imibhobho yezinto ezahlukeneyo ukuhlangabezana neemfuno zemimandla eyahlukeneyo, kubandakanywa ukwakhiwa, imboni yeekhemikhali, ukunikezelwa kwamanzi kunye nokukhupha, igesi kunye namanye amashishini.
