Ukuqonda izimiso zenqubo yokubumba amagagasi e-extrusion, izinzuzo, kanye nezici ezithonyayo

Ukubumba i-extrusion blow (EBM) inqubo esetshenziselwa ukukhiqiza amabhodlela epulasitiki angenalutho, izitsha, nezinye izimo kusetshenziswa i-polyethylene enesisindo esiphezulu (HDPE) noma i-polypropylene (PP). Kuhilela ukushisa ama-pellets epulasitiki noma ama-flakes abe sesimweni esincibilikisiwe, bese ekhishwa nge-diye ukuze kwakhiwe i-parison ebunjwe ngaphambilini. Le parison ibe isifuthwa ngomoya noma i-nitrogen, ipholiswe, bese ikhishwa ku-mold.

Izinzuzo ze-EBM zifaka phakathi ikhono layo lokukhiqiza izimo eziyinkimbinkimbi, amazinga aphezulu okukhiqiza, kanye namandla amahle omshini. Iphinde ibe nezindleko eziphansi uma kuqhathaniswa nezinye izinqubo zokubumba. Kodwa-ke, i-EBM ayifaneleki kuzo zonke izinto futhi ingadinga amathuluzi nemishini ekhethekile.

Ezinye izinto ezithonya i-EBM zifaka phakathi ukukhethwa kwezinto, ukwakheka komshini, izimo zenqubo, kanye nokwakheka kwesikhunta. Ukukhethwa kwezinto kubalulekile, njengoba izinto ezithile zinamaphuzu ahlukene okuncibilika, ukuqina, kanye nezakhiwo zokushisa. Ukwakheka komshini kumele kuqinisekise ukuhlanganiswa okufanele kwezinto, ukushisa, kanye nokupholisa ukuze kufezwe umphumela oyifunayo. Izimo zenqubo ezifana nokucindezela komjovo, isivinini sesikulufu, kanye nesikhathi sokupholisa zingathinta ikhwalithi yomkhiqizo wokugcina. Ukwakheka kwesikhunta kubalulekile ukuqinisekisa ikhwalithi yomkhiqizo omuhle, ukuhlanzwa kalula, kanye nokuthembeka kwesikhathi eside. Ngamafuphi, i-EBM iyinqubo yokubumba eguquguqukayo futhi engabizi kakhulu engakhiqiza izimo eziyinkimbinkimbi kanye namazinga aphezulu okukhiqiza. Kodwa-ke, idinga ukukhethwa kwezinto ngokucophelela, ukwakheka komshini, kanye nezimo zenqubo ukuqinisekisa umkhiqizo wokugcina osezingeni eliphezulu.
