Ukubumba nge-blow kuyinqubo yokukhiqiza esetshenziswa kabanzi yokwenza izingxenye zepulasitiki eziyize. Kuthandwa kakhulu ekukhiqizeni izitsha, amabhodlela neminye imikhiqizo ehlukahlukene. Inhliziyo yenqubo yokubumba nge-blow iwukubaumshini wokubumba nge-blow, okudlala indima ebalulekile ekubumbeni izinto zepulasitiki zibe umkhiqizo owufunayo. Kulesi sihloko, sizobheka izigaba ezine zokubumba nge-blow kanye nendlela umshini wokubumba nge-blow osiza ngayo isigaba ngasinye.
Ngaphambi kokuhlola isigaba ngasinye, kubalulekile ukuqonda ukuthi kuyini ukubumba nge-blow.Ukubumba nge-blowinqubo yokukhiqiza ehilela ukufutha ipayipi lepulasitiki elishisayo (elibizwa ngokuthi i-parison,) libe yisikhunta ukuze kwakhiwe into engenalutho. Le nqubo iyasebenza futhi ingabizi, okwenza kube ukukhetha okuthandwayo kokukhiqiza inani elikhulu lemikhiqizo yepulasitiki.
Izigaba ezine zokubumba ngegalelo:
Ukubumba nge-blow kungahlukaniswa ngezigaba ezine ezihlukene: ukukhipha, ukwakheka, ukupholisa kanye nokukhipha. Isigaba ngasinye sibalulekile empumelelweni iyonke yenqubo yokubumba nge-blow, kanti imishini yokubumba nge-blow yenza kube lula isigaba ngasinye.
1. Ukukhipha
Isigaba sokuqala sokubumba nge-blow yi-extrusion, lapho ama-pellet epulasitiki efakwa khona emshinini wokubumba nge-blow.umshini wokubumba nge-blowifudumeza ama-pellet epulasitiki aze ancibilike, yakha ithubhu eliqhubekayo lepulasitiki encibilikisiwe elibizwa ngokuthi i-parison. Inqubo yokukhipha ibalulekile ngoba inquma ukujiya kanye nokufana kwe-parison, okuthinta ngqo ikhwalithi yomkhiqizo wokugcina.
Kulesi sigaba, umshini wokubumba usebenzisa isikulufu noma i-plunger ukuze ucindezele ipulasitiki encibilikisiwe esikhumbeni ukuze kwakheke i-parison. Izinga lokushisa kanye nokucindezela kumele kulawulwe ngokucophelela ukuqinisekisa ukuthi ipulasitiki incibilikisiwe ngokuphelele futhi ingabunjwa kalula ezigabeni ezilandelayo.
2. Ukwakha
Uma i-parison isivele yakhekile, isigaba sokubumba siyangena. Kulesi sigaba, i-parison ifakwa esikhumbeni ukuze yakhe umkhiqizo wokugcina. Umshini wokubumba oshayayo ube usufaka umoya esikhumbeni, okwenza ukuthi sande size sigcwalise ngokuphelele isikhumbeni. Le nqubo yaziwa ngokuthi ukubumba okushayayo.
Ukwakheka kwesikhunta kubaluleke kakhulu njengoba kunquma usayizi wokugcina kanye nokuphela komkhiqizo. Kulesi sigaba, umshini wokubumba oshayayo kumele ulawule ngokunembile umfutho womoya kanye nokushisa ukuqinisekisa ukuthi i-parison ikhula ngokulinganayo futhi inamathela ezindongeni zesikhunta.
Umshini wokubumba we-LQ AS Injection-stretch-blow ngobuningi
1. Imodeli yochungechunge lwe-AS isebenzisa isakhiwo seziteshi ezintathu futhi ifaneleka ukukhiqiza izitsha zepulasitiki ezifana ne-PET, i-PETG, njll. Isetshenziswa kakhulu ezitsheni zokupakisha zezimonyo, zemithi, njll.
2. Ubuchwepheshe bokubumba ngokujova nokwelula nokushaya buqukethe imishini, isikhunta, izinqubo zokubumba, njll. I-Liuzhou Jingye Machinery Co., Ltd. ibilokhu icwaninga futhi ithuthukisa lobu buchwepheshe iminyaka engaphezu kweyishumi.
3. Umshini wethu Wokubumba Umjovo Nokwelula Umshini uneziteshi ezintathu: i-injection preform, i-strench & blow, kanye ne-ejection.
4. Le nqubo yesigaba esisodwa ingakongela amandla amaningi ngoba akudingeki uphinde ufudumale ama-preform.
5. Futhi ingaqinisekisa ukuthi ubukeka kahle ebhodleleni, ngokugwema ukuklwebhana kwangaphambi kwesikhathi.
3. Ukupholisa
Ngemva kokuba i-parison isifuthwe futhi yabunjwa, ingena esigabeni sokupholisa. Lesi sigaba sibalulekile ekuqiniseni ipulasitiki nokuqinisekisa ukuthi umkhiqizo wokugcina ugcina isimo sawo.Imishini yokubumba nge-blowngokuvamile zisebenzisa iziteshi zokupholisa noma umoya ukunciphisa izinga lokushisa lengxenye ebunjiwe.
Isikhathi sokupholisa siyahlukahluka kuye ngohlobo lwepulasitiki esetshenzisiwe kanye nobukhulu bomkhiqizo. Ukupholisa okufanele kubalulekile ngoba kuthinta izakhiwo zemishini kanye nekhwalithi iyonke yomkhiqizo wokugcina. Uma inqubo yokupholisa ingalawulwa kahle, ingabangela ukugoba noma ezinye izinkinga kumkhiqizo oqediwe.
4. Ukukhipha
Isigaba sokugcina sokubumba nge-blow ukukhushulwa. Uma umkhiqizo usupholile futhi uqinile,umshini wokubumba nge-blowivula isikhunta ukuze ikhulule umkhiqizo oqediwe. Lesi sigaba kumele senziwe ngokucophelela ukuze kugwenywe ukulimaza umkhiqizo. Umshini ungasebenzisa ingalo yerobhothi noma iphini lokukhipha ukuze kusize ekususeni ingxenye kusikhunta.
Ngemva kokukhipha umkhiqizo, umkhiqizo kungase kudingeke udlule kwezinye izinyathelo zokucubungula, njengokunqunywa noma ukuhlolwa, ngaphambi kokuba upakishwe futhi uthunyelwe. Ukusebenza kahle kwesigaba sokukhipha umkhiqizo kungaba nomthelela omkhulu emjikelezweni wokukhiqiza jikelele futhi ngenxa yalokho kuyingxenye ebalulekile yenqubo yokubumba.
Ukubumba nge-blow kuyinqubo yokukhiqiza ephumelelayo neguquguqukayo encike ekusebenzeni okunembile komshini wokubumba nge-blow. Ngokuqonda izigaba ezine zokubumba nge-blow (ukukhipha, ukwakha, ukupholisa kanye nokukhipha), kungenzeka ukuthola ukuqonda ngokukhiqizwa kwemikhiqizo yepulasitiki engenalutho. Isigaba ngasinye sidlala indima ebalulekile ekuqinisekiseni ikhwalithi kanye nokuvumelana komkhiqizo wokugcina.
Njengoba isidingo semikhiqizo yepulasitiki esezingeni eliphezulu siqhubeka nokukhula ezimbonini eziningi ezahlukene, intuthukoukubumba nge-blowubuchwepheshe kanye nemishini cishe kuzokwandisa ukusebenza kahle kanye nekhono lenqubo yokubumba nge-blow. Kungakhathaliseki ukuthi ungumkhiqizi, unjiniyela, noma umane unesifiso somhlaba wokukhiqizwa kwepulasitiki, ukuqonda lezi zigaba kuzojulisa ukuqonda kwakho ngobunzima kanye nokusungula izinto ezintsha ngemuva kwemishini yokubumba nge-blow.
