Ukubumba nge-blow kuyindlela yokwenzaukwakha imikhiqizo engenaluthongokusebenzisa ingcindezi yegesi ukuze kuvuvuke futhi kuvuvuke ama-embryo ashisayo ancibilikayo avaliwe esikhumbeni. Ukubumba okungenalutho kuwukukhipha kusuka ku-extruder bese ubeka i-tubular thermoplastic blank esesesimweni sokuthamba esikhumbeni sokubumba. Bese udlula emoyeni ocindezelwe, usebenzisa ingcindezi yomoya ukuze uguqule i-blank eceleni komgodi we-die, ngaleyo ndlela uvunguze ube yimikhiqizo engenalutho entanyeni emfushane.
Ukubumba okungenalutho kuyindlela ebaluleke kakhulu yokukhiqiza imikhiqizo yepulasitiki engenalutho.Cishe wonke ama-thermoplastic angasetshenziswa ekubumbeni okungenalutho, njenge-polyethylene, i-PVC, i-polypropylene, i-polystyrene, i-polyester eqondile, i-polycarbonate, i-polyamide, i-cellulose acetate kanye ne-poly acid formaldehyde resin, njll.
Ngalobu buchwepheshe bokubumba, akugcini nje ngokukwazikhiqiza encane ivolumuamabhodlela ama-milliliters amaningana, kodwa futhi angafakwakhiqizaizinkulungwane zamalithaivolumu enkuluimiphongolo kanye namathangi okugcina amanzi, kanye namabhola antantayo, amathangi kaphethiloli ezimoto kanye nama-kayak.
Yiziphi izici okufanele imikhiqizo yokubumba nge-blow ibe nazo?
1.Ukumelana nokuqhekeka kokucindezeleka kwemvelo: njengesitsha, inamandla okuvimbela ukuqhekeka lapho ihlangana ne-surfactant;
2.Ukuqina komoya (ukumelana nokungena kwamanzi): ibhekisela ezicini ezivimbela ukusabalala kwangaphandle komoya-mpilo, i-carbon dioxide, i-nitrogen kanye nomhwamuko wamanzi.
3.Ukumelana nokushaqeka: ukuze kuvikelwe izimpahla ezisesitsheni, imikhiqizo kufanele ibe nokumelana nokushayisana okungenakuhlukaniswa kusukela ekuphakameni kwemitha elilodwa.
4. Ngaphezu kwalokho, kukhona ukumelana nemithi, ukumelana okungaguquki, ukuqina kanye nokumelana nokukhishwa kwemithi.
Yiziphi izinzuzo zokubumba nge-blow?
1. Isakhiwo esingenalutho, esinodonga oluphindwe kabili singamunca futhi sisuse amandla okushaya;
2. Umklamo oguquguqukayo, osebenza kahle kakhulu kanye nezindleko zokukhiqiza eziphansi;
3. Ubuchwepheshe bokucubungula bungashintsha ukujiya kwe-embryo;
4. Ngesikhathi sokucubungula, ukujiya komkhiqizo kungashintshwa ngokuthanda ngaphandle kokuthuthukiswa kwesikhunta;
5. Ukubumba okuphansi kwengcindezi (ukucindezeleka kwangaphakathi kwesikhunta kuncane kakhulu kunokwakheka komjovo), ukuze kuthuthukiswe ukuzinza okulinganayo, ukumelana nokugqwala kwamakhemikhali kanye nokusebenza kokushisa okuphezulu;
6. Ukwehlukahluka kokuhlanganiswa: isikulufu sokuzithinta, i-die insert, i-fastener yokwandisa i-rivet;
7. Isikhunta esilula, izindleko eziphansi kanye nomjikelezo wokucubungula omfushane;
8. Isampula yesampula enentengo ephansi ingakhiqizwa ngokushesha.
Ukubumba nge-blow kuyinqubo yokukhiqiza lapho kwakhiwa khona izingxenye zepulasitiki eziyize: Kusetshenziswa futhi ekwakheni amabhodlela engilazi. Ngokuvamile, kunezinhlobo ezintathu eziyinhloko zokubumba nge-blow:ukubumba kwe-extrusion blow, ukubumba kwe-injection blow, kanye nokubumba kwe-injection stretch blow.

Ukusebenza okuzinzilenge-PLC ethuthukisiwe.
.Ukudlulisa ama-preform ngokuzenzakalelayonge-conveyor.
.Ukungena okunamandlakanye nokusatshalaliswa okuhle nokusheshayo kokushisa ngokuvumela amabhodlela ukuthi azungeze ngokwawo futhi aphendukele ezitimeleni ngesikhathi esisodwa ku-infrared preheater.
.Ukulungiswa okuphezuluukuze i-preheater ikwazi ukushisa ama-preforms ngezimo ngokulungisa ithubhu lokukhanya kanye nobude bebhodi elibonisa endaweni yokushisa, kanye nokushisa okuphakade ku-preheater ngedivayisi ye-thermostatic ezenzakalelayo.
.Ukuphepha okuphezulungemishini yokukhiya ngokuzenzakalelayo esenzweni ngasinye somshini, okuzokwenza izinqubo zibe yisimo sokuphepha uma kwenzeka inqubo ethile iphuka.
Ngokuyisisekeloukubumba nge-blowiyingxenye yepulasitiki engenalutho futhi ihlanganisa lezi zingxenye. Itholakala ngezimo nobukhulu obuhlukahlukene. Ukubumba nge-blow kanye nokubumba nge-injection kungenye yezindlela ezisetshenziswa kakhulu futhi ezisetshenziswa kakhulu ngale ndlela.khiqiza izingxenye zepulasitiki ezisezingeni eliphezulu ngentengo ephansingakho-ke le yindlela enhle nengabizi kakhulu. Ukubumba nge-Blow kuyindlela endala esetshenziswa ukudala izinto eziyize. Ekubumbeni nge-Blow kunezinto eziningi ezihilelekile njenge-“uhlobo lwepulasitiki, ijubane, isivinini, izinga lokushisa.Umoya ungenye yezinto ezibalulekile futhi udlala indima ebalulekile ekubumbeni nge-blow molding. Umoya ufakwa esikhumbeni ukuze uwandise futhi uwenze ube nesimo esifiselekayo. Inqubo yokubumba nge-blow molding ilula kakhulu, isetshenziswa kakhulu futhi ifaka imishini eshibhile, ukukhiqiza amabhodlela epulasitiki usebenzisa le nqubo kushibhile kakhulu uma kuqhathaniswa nokubumba nge-injection. Ekubumbeni nge-blow molding, isikhunta asidingeki ekwenzeni isikhunta esinokunemba okuphezulu.
Ukubumba nge-blow – inqubo yokukhiqiza eqondile kakhulu lapho kwakheka khona izingxenye zepulasitiki eziyizimbobo futhi zingahlanganiswa ndawonye.
Aumshini wokubumba nge-blowisetshenziswa kabanzi ekukhiqizweni kweziphuzo zezentengiselwano. Umshini wokubumba ibhodlela udala ibhodlela lepulasitiki ngokweresiphi, isibonelo ucacisa amandla ebhodlela okufanele lenziwe. Umshini uqukethe izikhunta, isilawuli se-logic esingahlelwa, kanye nezinsimbi zemishini neze-elekthronikhi.
