Yonke inqubo yokukhiqiza amabhodlela abunjwe nge-blow-mold (ukuthatha i-injection stretch blow molding yesinyathelo esisodwa njengesibonelo)
Umgomo oyinhloko ukufaka i-parison bese uyinweba bese uyifutha ngokushesha emshinini ofanayo. Le ndlela ifaneleka kakhulu ekukhiqizeni amabhodlela amanzi amaminerali e-PET asebenza kahle kakhulu namabhodlela eziphuzo.
Isinyathelo 1: Ukulungiswa kwezinto ezingavuthiwe kanye nokwelashwa kwangaphambi kwesikhathi
Izinto ezisetshenziswa kakhulu yi-PET (polyethylene terephthalate), futhi iyasebenza naku-PP, PC, njll.

Ukomisa: Izinto zokusetshenziswa ze-PET zinamandla amakhulu okuhlanza futhi kumele zomiswe ngokuqinile emazingeni okushisa aphezulu (njengama-150-180℃) kusetshenziswa umshini wokomisa osusa umswakama ukuze kuncishiswe okuqukethwe umswakama kube sezingeni eliphansi kakhulu (njengangaphansi kuka-0.005%). Lesi yisihluthulelo sokuqinisekisa ukuthi ibhodlela licacile futhi aliqhekeki.

Isinyathelo 2: Ukubumba umjovo we-parison
Ama-PET pellets omisiwe amuncwa emgqonyeni womshini wokubumba umjovo bese eshiswa futhi enziwe ngepulasitiki abe sesimweni sokuncibilika.

Ukuncibilika kufakwa ku-parison mold ngesikulufu somjovo ukuze kwakheke i-parison ecacile ngesimo se-test tube.

Ingxenye yomlomo webhodlela ye-parison isivele yakheke ngokuphelele futhi yafinyelela ukunemba kokugcina kobukhulu kulesi sigaba.

Isinyathelo 3: Ukulungiswa kwezinga lokushisa kwe-parison
I-hot parison eyakhiwe idluliselwa esiteshini sokulawula izinga lokushisa. Phakathi nale nqubo, i-parison ipholiswa ngokulinganayo kuze kube sebangeni lokushisa elifanele kakhulu ukwelulwa (cishe 90-110℃). Ukufana kwezinga lokushisa kuyisihluthulelo sokuqinisekisa ikhwalithi yokubumba okulandelayo.

Isinyathelo 4: Ukwelula nokufaka umoya
Lesi yisinyathelo esibaluleke kakhulu, esiqedwa ngaphakathi kwesikhunta sokubumba esishaywayo.

Ukwelula okude: Isikhunta sokubumba esishayayo siyavalwa, bese kufakwa induku yokulula kusukela phezulu kuya phansi eparison ukuze ilulwe ngobude iye phansi kwesikhunta.

Ukufutha ngomfutho ophezulu: Ngesikhathi esifanayo, umoya ocindezelekile kakhulu (ngokuvamile u-20-40 bar) uvuthelwa usuka phezulu kwenduku yokunwebeka, uvuthe i-parlet eceleni njengebhaluni bese unamathela ngokuqinile odongeni lwangaphakathi lwesikhunta sokufutha esibandayo.

Isinyathelo 5: Phola bese usetha
Ibhodlela ligcinwa licindezelwe esikhumbeni sokubumba bese lipholiswa imizuzwana embalwa ukuze lilungise ukuma kwalo. Imisele yamanzi epholile ngaphakathi kwesikhumbeni izosusa ukushisa ngokushesha.

Isinyathelo 6: Vula isikhunta bese ususa
Isikhunta sokubumba esivulwa siyavulwa, bese amabhodlela akhiwe akhishwa ngesandla somshini bese edluliselwa ezinqubweni ezilandelayo.

Isinyathelo 7: Ukuhlolwa kwekhwalithi ngemuva kokucubungula
Ukusika: Susa i-flash eyengeziwe (isibambo sezinto ezibonakalayo) emlonyeni webhodlela.

Ukutholwa

Ukutholwa komthamo: Qinisekisa ukunemba kwenani lokugcwalisa.

Ukuhlolwa kokusebenza kokuvala: Hlola ukuthi usayizi womlomo webhodlela kanye nentambo kuyafaneleka yini.

Ukutholwa kobukhulu bodonga: Sebenzisa i-ultrasound ukujiya ukuqinisekisa ukujiya okufanayo komzimba webhodlela, ikakhulukazi phansi nasemahlombe.

Ukuhlolwa kwengcindezi: Kumabhodlela eziphuzo ezine-carbonated, kudingeka ukuhlolwa kokumelana nengcindezi kwangaphakathi.
