cryogenic defiashing tekinoroji yahimbwe bwa mbere muri 1950.Mubikorwa byiterambere bya cryogenic defiashingmachines, byanyuze mubihe bitatu byingenzi.Kurikira hamwe niyi ngingo kugirango ubashe gusobanukirwa muri rusange.
(1) Imashini ya mbere ya cryogenic deflashing
Ingoma yahagaritswe ikoreshwa nkibikoresho bikora kugirango bikonje, kandi urubura rwumye rwatoranijwe bwa mbere nka firigo.Ibice bigomba gusanwa byashyizwe mu ngoma, birashoboka ko hiyongereyeho ibitangazamakuru bikora bivuguruzanya.Ubushyuhe buri imbere yingoma bugenzurwa kugirango bugere kuri reta aho impande zacitse mugihe ibicuruzwa ubwabyo bikomeje kutagira ingaruka.Kugirango ugere kuriyi ntego, ubunini bwimpande bugomba kuba ≤0.15mm.Ingoma nigice cyibanze cyibikoresho kandi ni umunani.Urufunguzo ni ukugenzura ingaruka zamakuru yatangajwe, kwemerera kuzenguruka kugaragara inshuro nyinshi.
Ingoma izunguruka ku isaha yerekeza ku isaha kugirango igwe, kandi nyuma yigihe runaka, flash impande ziba zoroshye kandi inzira yo kurangiza irarangiye.Ubusembwa bwibisekuru byambere byahagaritswe gukonjesha ni impande zuzuye, cyane cyane flash zasigaye kumpera yumurongo wo gutandukana.Ibi biterwa nigishushanyo kidahagije cyangwa ubunini bukabije bwurwego rwa reberi kumurongo wo gutandukana (kurenza 0.2mm).
（2 machine Imashini ya kabiri ya cryogenic deflashing
Imashini ya kabiri ya cryogenic deflashing yakoze ibintu bitatu byateye imbere ukurikije igisekuru cya mbere.Ubwa mbere, firigo ihindurwamo azote yuzuye.Urubura rwumye, hamwe na sublimation ya -78.5 ° C, ntirukwiriye kubutaka bumwebumwe bwo hasi bwo hasi, nka reberi ya silicone.Azote y'amazi, ifite aho itetse -195.8 ° C, ikwiriye ubwoko bwose bwa reberi.Icya kabiri, hari byinshi byahinduwe kuri kontineri ifata ibice kugirango bigabanuke.Yahinduwe kuva ingoma izunguruka ihinduka umukandara umeze nk'umukandara.Ibi bituma ibice bigwa muri ruhago, bikagabanya cyane kugaragara ahantu hapfuye.Ibi ntabwo bitezimbere imikorere gusa ahubwo binongera ubusobanuro bwuruhande.Icya gatatu, aho kwishingikiriza gusa kugongana hagati yibice kugirango ukureho flash flash, hashyizweho itangazamakuru ryiza cyane.Ibyuma bya pulasitiki byuma cyangwa bikomeye bifite ubunini bwa 0.5 ~ 2mm biraswa hejuru yibice ku muvuduko wa 2555m / s, bigatera imbaraga zikomeye.Iri terambere rigabanya cyane igihe cyinzira.
（3 machine Imashini ya gatatu ya cryogenic deflashing
Imashini ya gatatu ya cryogenic deflashing ni iterambere rishingiye ku gisekuru cya kabiri.Igikoresho kugirango ibice bigabanuke bihindurwe igitebo cyibice hamwe nurukuta.Ibyo byobo bitwikiriye urukuta rw'igitebo hamwe na diametero ya 5mm (iruta umurambararo wa diameter) kugira ngo ibisasu bitambukire mu mwobo neza hanyuma bigaruke hejuru y'ibikoresho kugirango bongere bikoreshe.Ibi ntabwo byagura gusa ubushobozi bukomeye bwa kontineri ahubwo binagabanya ingano yububiko bwibitangazamakuru byingaruka (ibisasu) .Igitebo cyibice ntabwo gihagaze neza mumashini yo gutema, ariko gifite impengamiro runaka (40 ° ~ 60 °).Inguni ihindagurika itera igitebo kunyeganyega cyane mugihe cyo gutema bitewe no guhuza imbaraga ebyiri: imwe ni imbaraga zo kuzunguruka zitangwa nigitebo ubwacyo ziratemba, naho ubundi nimbaraga za centrifugal zatewe ningaruka ziterwa nigisasu.Iyo izo mbaraga zombi zahujwe, habaho 360 ° icyerekezo cyose kibaho, bigatuma ibice bivanaho impande zose kandi byuzuye mubyerekezo byose.
