Gukubita ibicu, bizwi kandi nka hollow blow molding, nuburyo bwihuse bwo gutunganya plastike.Mu Ntambara ya Kabiri y'Isi Yose, uburyo bwo kubumba bwatangiye gukoreshwa kugira ngo habeho inzabya nke za polyethylene.Mu mpera z'imyaka ya za 1950, hamwe no kuvuka kwa polyethylene yuzuye kandi hanatezwa imbere imashini zikora imashini, ikoreshwa rya tekinoroji.Ingano yububiko butagaragara irashobora kugera kuri litiro ibihumbi, kandi umusaruro umwe wagenzuye mudasobwa.Amashanyarazi akwiranye no kubumba harimo polyethylene, chloride polyvinyl, polypropilene, polyester, nibindi. Ibikoresho bivamo ubusa bikoreshwa cyane nkibikoresho byo gupakira inganda.Ukurikije uburyo bwo gutanga umusaruro wa paruwasi, gushushanya bishobora kugabanywa mu gusohora no guterwa inshinge.Ibishya byateye imbere ni ibice byinshi byo guhanagura no kurambura.
Gutera inshinge
Kugeza ubu, tekinoroji yo gutera inshinge ikoreshwa cyane kuruta gutera inshinge.Ubu buryo bwo guhumeka nuburyo bwo gutera inshinge, ariko byongera gusa impagarara za axial, bigatuma guhumeka byoroha no kugabanya gukoresha ingufu.Ingano yibicuruzwa bishobora gutunganywa no gushushanya inshinge no kuvuza ni binini kuruta ibyo gutera inshinge.Ingano ya kontineri ishobora guhuha ni 0.2-20L, kandi imikorere yayo niyi ikurikira:
1. Ihame ryo kubumba inshinge nimwe nkiyo gutera inshinge zisanzwe.
2. Noneho hindura parison muburyo bwo gushyushya no gushyushya ubushyuhe kugirango parison yoroshye.
3. Hindukirira kuri sitasiyo ikurura hanyuma ufunge ifumbire.Inkoni yo gusunika mu nsi irambuye parison yerekeza ku cyerekezo cya axial, mugihe uhuha umwuka kugirango parison yegereye urukuta rwubatswe kandi ikonje.
4. Kwimura kuri sitasiyo ya demoulding kugirango ufate ibice
Icyitonderwa - gukurura - kuvuza inzira:
Gutera inshinge parison → gushyushya parison → gufunga, gushushanya no kuvuza → gukonjesha no gufata ibice
Igishushanyo mbonera cyimiterere yuburyo bwo gutera inshinge, gushushanya no kuvuza
Gukuramo ibicuruzwa
Gukuramo ibishishwa ni bumwe muburyo bukoreshwa cyane.Urwego rwo gutunganya ni rugari cyane, kuva ku bicuruzwa bito kugeza kuri kontineri nini n'ibice by'imodoka, ibikomoka ku miti yo mu kirere, n'ibindi. Uburyo bwo gutunganya ni ubu bukurikira:
1. Ubwa mbere, gushonga no kuvanga reberi, hanyuma gushonga byinjira mumashini kugirango bibe parison ya tubular.
2. Iyo gereza imaze kugera ku burebure bwateganijwe, ifumbire mvaruganda irafungwa kandi gereza ifatirwa hagati y’ibice byombi.
3. Hisha umwuka, uhumeke umwuka muri gereza, uhuhishe gereza kugirango wegere umwobo wububiko.
4. Ibicuruzwa bikonje
5. Fungura ifu hanyuma ukureho ibicuruzwa bikomeye.
Gukuramo ibicuruzwa biva mu mahanga:
Gushonga → gusohora parison → gufunga ibumba no guhuha → gufungura no gufata igice
Igishushanyo mbonera cya extrusion blow molding ihame
(1 - umutwe wa extruder; 2 - guhuha;
Gutera inshinge
Gutera inshinge ni uburyo bwo kubumba buhuza ibiranga inshinge.Kugeza ubu, ikoreshwa cyane cyane kumacupa yo kunywa, amacupa yimiti nibice bimwe na bimwe bito byubatswe neza.
1. Muri sitasiyo yo gutera inshinge, urusoro rwambere rwatewe inshinge mbere, kandi uburyo bwo gutunganya ni bumwe nuburyo busanzwe bwo gutera inshinge.
2. Nyuma yo gufungura inshinge, mandel na parison byimukira kuri sitasiyo.
3. Mandel ishyira parison hagati yikubitiro no gufunga ifumbire.Noneho, umwuka wafunitse uhuhwa muri gereza unyuze hagati ya mandel, hanyuma ugahuha kugirango ube hafi y'urukuta rwubatswe hanyuma ukonje.
4. Iyo ifumbire ifunguye, mandel yimurirwa kuri sitasiyo.Nyuma yo gukuramo ibice byo gukuramo, mandel yimurirwa kuri sitasiyo yo gutera inshinge.
Igikorwa cyo gutera inshinge:
Gukubita parison parison → gufungura inshinge gufungura kuri sitasiyo yerekana firime → gufunga ibumba, guhanagura no gukonjesha → kuzunguruka kuri sitasiyo kugirango ufate ibice → parison
Igishushanyo mbonera cyo gutera inshinge ihame
Ibyiza n'ibibi byo gutera inshinge:
akarusho
Igicuruzwa gifite imbaraga zingana kandi zisobanutse neza.Ntaho bihurira kuri kontineri kandi nta mpamvu yo gusana.Gukorera mu mucyo no hejuru yubuso bwibice byahinduwe nibyiza.Ikoreshwa cyane mubikoresho bya plastiki bikomeye hamwe nubunini bwagutse.
kubura
Igiciro cyibikoresho byimashini ni kinini cyane, kandi gukoresha ingufu ni byinshi.Mubisanzwe, ibintu bito gusa (munsi ya 500ml) birashobora gushingwa.Biragoye gukora kontineri ifite imiterere igoye nibicuruzwa bya elliptique.
Yaba ari inshinge zo gutera inshinge, inshinge zo gukurura inshinge, gukuramo gukurura ibishishwa, bigabanijwemo inshuro imwe no kubumba inshuro ebyiri.Igikorwa cyo kubumba inshuro imwe gifite automatike yo hejuru, ibisobanuro bihanitse byo gufunga parison no kwerekana sisitemu, hamwe nigiciro cyibikoresho byinshi.Mubisanzwe, abayikora benshi bakoresha uburyo bwo kubumba inshuro ebyiri, ni ukuvuga, kubumba gereza mbere binyuze mu guterwa inshinge cyangwa kuyikuramo, hanyuma bagashyira parison muyindi mashini (imashini itera inshinge cyangwa imashini ikurura inshinge) kugirango bahoshe ibicuruzwa byarangiye, hamwe na hejuru umusaruro ushimishije.
