Ifilimu engu-0.5 mil (12.7 micron) ekhiqizwe kusetshenziswa i-grooved-feed extruder enenani elingu-225 lb/h enobude besiqu obungu-7 x Die Diameter, i-4:1 Blow-Up Ratio (BUR), ububanzi obuyi-intshi engu-6 futhi igebe lokufa elingu-0.040 intshi. Izakhiwo ezivamile ezibikwe lapha zimele umkhiqizo ngaphansi kwalezi zimo zokucubungula, nakuba izakhiwo zefilimu zingahluka kuye ngezimo ezithile zokufutha ifilimu. Ngakho-ke, idatha akufanele isetshenziselwe izinjongo ezicacisiwe.
Ngaphambi kokusebenzisa lo mkhiqizo, umsebenzisi uyelulekwa futhi axwayiswe ukuthi azinqumele kanye nokuhlola ukuphepha kanye nokuphepha.ukufaneleka komkhiqizo ekusetshenzisweni okuqondile okukhulunywa ngakho futhi uyelulekwa ngokumelene nokuncika olwazini oluqukethwelapha njengoba kungase kuhlobane nanoma yikuphi ukusetshenziswa noma uhlelo oluthile. Kungumsebenzi wokugcina womsebenzisi ukuqinisekisa ukuthi umkhiqizo unjalokufanelekile futhi ulwazi lusebenza kuhlelo lokusebenza oluthile lomsebenzisi. I-Chevron Phillips Chemical Company LP ayifunienze, futhi akhiphe ngokusobala, zonke iziqinisekiso, okuhlanganisa iziqinisekiso zokuthengisa noma ukufaneleka kwenjongo ethile,kungakhathalekile ukuthi ngomlomo noma kubhaliwe, kuyavezwa noma kushiwo, noma kusolwa noma yikuphi ukusetshenziswa kwanoma yikuphi ukuhweba noma kunoma iyiphi inkamboeziphathelene nokusetshenziswa kolwazi oluqukethwe lapha noma umkhiqizo ngokwawo. Umsebenzisi uthatha ngokusobala yonke ingozikanye nesikweletu, kungakhathaliseki ukuthi sisekelwe esivumelwaneni, sobugebengu noma ngenye indlela, mayelana nokusetshenziswa kolwazi oluqukethwe lapha nomaumkhiqizo ngokwawo. Ngaphezu kwalokho, ulwazi oluqukethwe lapha lunikezwa ngaphandle kokubhekisela kunoma yiziphi izinkinga zempahla yengqondo, futhinjengeimithetho yombuso, yezwe noma yendawo okungase kuhlangatshezwene nayo ekusetshenzisweni kwayo. Imibuzo enjalo kufanele iphenywe ngumsebenzisi.
