Inqubo yokubumba izinto zokupakisha zepulasitiki embonini yezimonyo ihlukaniswe kakhulu ngezigaba ezimbili: ukubumba ngomjovo kanye nokubumba nge-blow.
Ukubumba Ngomjovo
Iyini inqubo yokubumba ngomjovo?
Ukubumba ngomjovo kuyinqubo yokushisa nokwenza ipulasitiki ibe yipulasitiki (ukufudumeza nokuncibilikisa kube uketshezi, ipulasitiki), bese usebenzisa ingcindezi ukuze uyifake endaweni evaliwe yesikhunta, okukuvumela ukuthi iphole futhi iqine esikhunta, ukuze kukhiqizwe umkhiqizo onesimo esifanayo nesikhunta. Ifanele ukukhiqizwa ngobuningi kwezingxenye ezinezimo eziyinkimbinkimbi.
Izici zenqubo yokubumba umjovo:
1. Isivinini sokukhiqiza esisheshayo, ukusebenza kahle okuphezulu, izinga eliphezulu lokusebenza okuzenzakalelayo
2. Umkhiqizo unokunemba okuphezulu, futhi iphutha lokubukeka lincane kakhulu
3. Iyakwazi ukukhiqiza izingxenye ezinezimo eziyinkimbinkimbi
4. Izindleko eziphezulu zesikhunta
Iningi lethuibhodlela elingenamoya, ibhodlela lokugcoba elinodonga oluphindwe kabilizikhiqizwa ngenqubo yokujova.
Ukubumba nge-blow
Izici zenqubo yokubumba ngegalelo:
Ukuthatha izifundo ezivela enkambisweni yendabuko yokufutha ingilazi, ukubumba nge-blow kusebenzisa umoya ocindezelwe onomfutho othile ukuze kufuthe futhi kupholise i-preform (umzimba wepulasitiki oshubhu oqediwe kancane) esikhumbeni ibe yinqubo yokubumba yemikhiqizo engenalutho. Ifanele ukukhiqizwa ngobuningi kwezitsha zepulasitiki ezingenalutho.
Yiziphi izici zenqubo yokubumba nge-blow?
1. Indlela elula yokukhiqiza, ukusebenza kahle kokukhiqiza okuphezulu kanye nokwenza izinto ngokuzenzakalela
2. Ukunemba okuphansi kobukhulu
3. Kunemikhawulo ethile ngesimo somkhiqizo
4. Izindleko eziphansi zesikhunta
Ngokwezinyathelo nezinqubo ezahlukene zokukhiqiza, ukubumba nge-blow kungahlukaniswa ngezinhlobo ezintathu: ukuvunguza kwe-extrusion, ukuvunguza nge-injection, kanye nokuvunguza nge-injection stretch.
Okokuqala ukucindezela nokuvunguza. Njengoba igama lisikisela, ukuqhuma kokukhipha kunezinyathelo ezimbili ezinkulu: ukuqhuma kokukhipha kanye nokubumba kokuqhuma.
Isinyathelo sokuqala ukukhipha ukuvalwa kwe-parison-mold.Idivayisi yokukhipha iqhubeka nokucindezelwa ukuze yakhe i-parison engenalutho.Uma i-parison ikhishwa ibe nobude obunqunyiwe, ingxenye ephezulu ye-parison iyanqunywa ibe nobude obufanele ucezu olulodwa, bese izimbobo ezinhlangothini zesobunxele nakwesokudla zivaliwe.
Isinyathelo sesibili, ukwethulwa komoya - ukucheba.Umoya ocindezelwe ufakwa ku-preform nge-mandrel ukuze uvuvuke.I-parison inamathela eduze odongeni lwangaphakathi lwesikhunta ukuze iphole futhi ibumbeke, bese umkhiqizo ususwa kusikhunta, bese kwenziwa ukucheba kwesibili.Izindleko zokukhipha kanye nemishini yokufutha kanye nezikhunta ziphansi kakhulu, kanti nezindleko zokukhiqiza nazo ziphansi kakhulu.
Kodwa-ke, ukukhanya kwenzeka ngesikhathi senqubo yokukhiqiza, futhi umlomo kanye nesisekelo sebhodlela kudingeka kulungiswe ngomshini noma ngesandla, futhi ngezinye izikhathi umlomo webhodlela udinga ukupholishwa nokunqunywa.
Amabhodlela epulasitiki abunjwe nge-extrusion-blow anomugqa wokuhlukana (i-linear protrusion) phansi, kanti umlomo webhodlela uqinile futhi awubushelelezi, ngakho-ke amanye anengozi yokuvuza koketshezi. Amabhodlela anjalo avame ukwenziwa ngezinto ze-PE futhi asetshenziswa ezimonyweni ezifana namabhodlela e-foam, ama-lotion omzimba, ama-shampoo kanye nama-conditioner.
Uhlobo lwesibili ukufutha nge-injection, olunezinyathelo ezimbili ezinkulu: ukubumba nge-injection-blow.
Isinyathelo 1: Lungisa ukuvalwa kwesikhunta nge-injection.
Sebenzisa inqubo yokubumba ngomjovo ukuze ukhiqize i-parison engezansi, bese ikhonsoli ijikeleza ngo-120° kuya kusixhumanisi sokubumba ngomjovo.
Isikhunta siyavalwa, bese umoya ocindezelwe ufakwa epharison nge-mandrel pores ukuze kufakwe isikhunta.
Isinyathelo sesi-2: Lungisa ukupholisa nokususa ukwehla kwamandla emali.
Ngemva kokuba umkhiqizo oboshiwe usupholile ngokuphelele futhi wabunjwa, ikhonsoli ijikeleza ngo-120° ukuze ihambise umkhiqizo. Asikho isidingo sokunciphisa okwesibili, ngakho izinga lokuzenzakalela kanye nokusebenza kahle kokukhiqiza liphezulu. Ngenxa yokuthi ibhodlela livuthelwa kusuka ku-parison eboshiwe ngomjovo, umlomo webhodlela uyisicaba futhi ibhodlela linezakhiwo zokuvala ezingcono, njenge-Uchungechunge lwamabhodlela oluvuthelayo lwe-TB07.
Uhlobo lwesithathu ukudonsa amanothi nokuwashaya. Luhlukaniswe ngezinyathelo ezintathu: ukubumba ngomjovo-ukwelula-ukushaya.
Ngokungafani nohlobo lokuvuthela ngomjovo olujikayo, ukuvuthela ngomjovo kuwumkhiqizo womugqa wokuhlanganisa.
Isinyathelo 1: Lungisa ukuvalwa kwesikhunta nge-injection
Faka i-preform ekhiqizwe ngomjovo esikhumbeni sokushaya
Faka induku yokwelula bese uvala isikhunta kwesobunxele nakwesokudla
Isinyathelo 2: Ukunweba-Ukushaya-Ukupholisa kanye nokususa i-upper
Induku yokwelula inwetshwa ngobude, kuyilapho umoya ufakwa ngenduku yokwelula ukuze kwelulwe ohlangothini
Ukupholisa nokubumba, ukususa nokukhipha umkhiqizo
Ukufutha kokwelula ngomjovo yikona okunekhwalithi ephezulu, ukunemba kanye nezindleko enqubweni yokubumba ngomjovo.
Njengamanje, kunezindlela ezimbili zokukhiqiza enqubweni yokuvunguza ngomjovo, ezibizwa ngokuthi: indlela yesinyathelo esisodwa kanye nendlela yesinyathelo ezimbili. Ukubumba ngomjovo kanye nokubumba ngomjovo kuqedwa ndawonye ngendlela yesinyathelo esisodwa, kanti lezi zinyathelo ezimbili ziqedwa ngokuzimela njengendlela yesinyathelo ezimbili.
Uma kuqhathaniswa nendlela yezinyathelo ezimbili, indlela yesinyathelo esisodwa iqedwa ngemishini yesinyathelo esisodwa kusukela ezintweni zokusetshenziswa kuya kumkhiqizo oqediwe. Inqubo yokukhiqiza ilula futhi akukho ukushisa kwesibili okuvunyelwe, ngakho ukusetshenziswa kwamandla kuphansi.
Indlela enezinyathelo ezimbili idinga ukujova kokuqala ngaphambi kokwenza i-preform, bese kuba ukucutshungulwa kwesibili emshinini wokubumba. Ukubumba ngokufutha kudinga ukufudunyezwa kwesibili kwe-preform epholile, ngakho-ke ukusetshenziswa kwamandla kuphezulu.
