I-Blow molding iyinqubo yokukhiqiza esetshenziswa kabanzi yokwenza izingxenye zepulasitiki ezingenalutho. Idume kakhulu ekukhiqizeni iziqukathi, amabhodlela neminye imikhiqizo ehlukahlukene. Enhliziyweni yenqubo yokubumba i-blow yi-shayela umshini wokubumba, edlala indima ebalulekile ekubumbeni izinto zepulasitiki zibe umkhiqizo owufunayo. Kulesi sihloko, sizobheka izigaba ezine zokubunjwa kwe-blow kanye nokuthi umshini wokubumba umshini usiza kanjani isigaba ngasinye.
Ngaphambi kokungena esigabeni ngasinye, kubalulekile ukuqonda ukuthi kuyini ukubunjwa kwe-blow.Vuthela ukubumbakuyinqubo yokukhiqiza ehilela ukufutha ishubhu lepulasitiki elishisayo (elibizwa ngokuthi i-parison,) libe isikhunta ukuze kwakhe into engenalutho. Le nqubo iyasebenza futhi iyathengeka, okwenza kube ukukhetha okudumile ukukhiqiza inani elikhulu lemikhiqizo yepulasitiki.
Izigaba ezine zokubumba igalelo:
Ukubumba i-Blow kungahlukaniswa ngezigaba ezine ezihlukene: i-extrusion, ukwakha, ukupholisa kanye nokukhipha. Isigaba ngasinye sibalulekile empumelelweni yonke yenqubo yokubumba igalelo, futhi imishini yokubumba ivuthela yenza lula isigaba ngasinye.
1. Extrusion
Isigaba sokuqala sokubunjwa kokushaywa yi-extrusion, lapho ama-pellets epulasitiki afakwa emshinini wokubumba. Ishayela umshini wokubumbakushisisa ama-pellets epulasitiki aze ancibilike, akhe ishubhu lepulasitiki elincibilikisiwe elibizwa ngokuthi i-parison. Inqubo ye-extrusion ibalulekile ngoba inquma ukushuba nokufana kwe-parison, okuthinta ngokuqondile ikhwalithi yomkhiqizo wokugcina.
Kulesi sigaba, umshini wokubumba i-blow usebenzisa isikulufu noma i-plunger ukusunduza ipulasitiki encibilikisiwe esikhunjeni ukwenza i-parison. Izinga lokushisa nokucindezela kufanele kulawulwe ngokucophelela ukuze kuqinisekiswe ukuthi ipulasitiki incibilika ngokuphelele futhi ingabunjwa kalula ezigabeni ezilandelayo.
2. Ukwakha
Lapho i-parson yakhiwe, isiteji sokubumba singena. Kulesi sigaba, i-parison iboshelwe esikhunjeni ukuze ilolonge umkhiqizo wokugcina. Umshini wokubumba i-blow ube usungenisa umoya etilongweni, uwenze wande uze ugcwalise ngokuphelele isikhunta. Le nqubo yaziwa ngokuthi i-blow molding.
Idizayini yesikhunta ibalulekile njengoba inquma ubukhulu bokugcina kanye nokuqedwa kwendawo yomkhiqizo. Kulesi sigaba, umshini wokubumba umshini kufanele ulawule ngokunembile ukucindezela komoya kanye nezinga lokushisa ukuze uqinisekise ukuthi i-parison ikhula ngokufanayo futhi inamathela ezindongeni zesikhunta.
1. Imodeli yochungechunge lwe-AS isebenzisa isakhiwo seziteshi ezintathu futhi ifanele ukukhiqiza iziqukathi zepulasitiki ezifana ne-PET, i-PETG, njll. Isetshenziselwa ikakhulukazi iziqukathi zokupakisha zezimonyo, ezemithi, njll.
2. Ubuchwepheshe bokubumba umjovo we-stretch-blow buqukethe imishini, isikhunta, izinqubo zokubumba, njll. I-Liuzhou Jingye Machinery Co., Ltd. ibicwaninga futhi ithuthukisa lobu buchwepheshe iminyaka engaphezu kweshumi.
3. Umshini wethu Wokubumba Umjovo-Welula-we-Stretch-Blow uneziteshi ezintathu: i-preform yomjovo, ukunwebeka nokushaywa, kanye nokukhipha.
4. Le nqubo yesiteji esisodwa ingakongela amandla amaningi ngoba awudingi ukushisisa kabusha ama-preforms.
5. Futhi ingakuqinisekisa ukubukeka kwakho kwebhodlela okungcono, ngokugwema ama-preforms ukuklwebheka.
3. Ukupholisa
Ngemuva kokuthi i-parison ivuthwe futhi ibunjwe, ingena esigabeni sokupholisa. Lesi sigaba sibalulekile ekwelapheni ipulasitiki nokuqinisekisa ukuthi umkhiqizo wokugcina ugcina umumo wawo.Imishini yokubumbangokuvamile sebenzisa iziteshi zokupholisa noma umoya ukuze unciphise izinga lokushisa lengxenye ebunjiwe.
Isikhathi sokupholisa siyahlukahluka kuye ngohlobo lwepulasitiki esetshenziswayo kanye nobukhulu bomkhiqizo. Ukupholisa okufanele kubalulekile ngoba kuthinta izakhiwo zemishini kanye nekhwalithi iyonke yomkhiqizo wokugcina. Uma inqubo yokupholisa ingalawulwa kahle, ingase ibangele i-warpage noma okunye ukonakala emkhiqizweni osuphelile.
4. Ukukhishwa
Isigaba sokugcina sokubunjwa kokushaywa yi-ejection. Uma umkhiqizo usupholile futhi uqina, i-shayela umshini wokubumbaivula isikhunta ukuze ikhulule umkhiqizo ophelile. Lesi sigaba kufanele senziwe ngokucophelela ukugwema ukulimaza umkhiqizo. Umshini ungase usebenzise ingalo yerobhothi noma iphinikhodi ye-ejector ukusiza ekukhipheni ingxenye esikhunjeni.
Ngemva kokukhishwa, umkhiqizo kungase kudingeke udlule kwezinye izinyathelo zokucubungula, njengokusikwa noma ukuhlolwa, ngaphambi kokuthi upakishwe futhi uthunyelwe. Ukusebenza kahle kwesiteji sokukhipha kungaba nomthelela omkhulu kumjikelezo wokukhiqiza wonkana ngakho-ke kuyingxenye ebalulekile yenqubo yokubumba igalelo.
I-Blow molding iyinqubo yokukhiqiza ephumelelayo futhi eguquguqukayo encike ekusebenzeni okunembile komshini wokubumba i-blow. Ngokuqonda izigaba ezine zokubumba igalelo (i-extrusion, ukwakha, ukupholisa kanye nokukhishwa), kungenzeka ukuthola ukuqonda ekukhiqizeni imikhiqizo yepulasitiki engenalutho. Isigaba ngasinye sidlala indima ebalulekile ekuqinisekiseni ikhwalithi nokuvumelana komkhiqizo wokugcina.
Njengoba isidingo semikhiqizo yepulasitiki yekhwalithi ephezulu siqhubeka nokukhula kuzo zonke izimboni eziningi, intuthuko ithuthukavuthela ukubumbaubuchwepheshe kanye nemishini kungenzeka kwandise ukusebenza kahle kanye nekhono lenqubo yokubumba igalelo. Noma ngabe ungumkhiqizi, unjiniyela, noma umane unentshisekelo emhlabeni wokukhiqiza amapulasitiki, ukuqonda lezi zigaba kuzojulisa ukuqonda kwakho ngobunkimbinkimbi kanye nokuqanjwa okusha ngemuva kwemishini yokubumba i-blow.
