Ukadaulo wa cryogenic defiashing Adapangidwa mu 1950s.Pakupanga makina a cryogenic defiashing, adadutsa nthawi zitatu zofunika.Tsatirani m'nkhaniyi kuti mumvetse bwino.
(1) Makina oyambira a cryogenic deflashing
Ng'oma yozizira imagwiritsidwa ntchito ngati chidebe chosungiramo madzi oundana, ndipo ayezi wowuma amasankhidwa ngati firiji.Ziwalo zomwe ziyenera kukonzedwa zimayikidwa mu ng'oma, mwinamwake ndi kuwonjezera zina zotsutsana zogwira ntchito.Kutentha mkati mwa ng'oma kumayendetsedwa kuti ifike kumalo kumene m'mphepete mwake ndi brittle pamene mankhwalawo amakhalabe osakhudzidwa.Kuti mukwaniritse cholinga ichi, makulidwe a m'mphepete mwake ayenera kukhala ≤0.15mm.Ng'oma ndiye chigawo chachikulu cha zida ndipo ndi octagonal mu mawonekedwe.Chofunikira ndikuwongolera zomwe zimakhudzidwa ndi media zomwe zatulutsidwa, zomwe zimapangitsa kuti kuzungulira kuchitike mobwerezabwereza.
Ng'oma imazungulira mozungulira koloko kuti igwe, ndipo pakapita nthawi, m'mphepete mwa ng'omayo imakhala ngati brittle ndipo njira yowongolera imatsirizika.Chilema cha m'badwo woyamba wozizira edging ndi chosakwanira edging, makamaka zotsalira zong'anima m'mphepete kumapeto kwa mzere wolekanitsa.Izi zimachitika chifukwa cha kusakwanira kwa nkhungu kapena makulidwe ochulukirapo a mphira pamzere wolekanitsa (woposa 0.2mm).
(2) Makina achiwiri a cryogenic deflashing
Makina achiwiri a cryogenic deflashing apanga zosintha zitatu kutengera m'badwo woyamba.Choyamba, refrigerant imasinthidwa kukhala nayitrogeni wamadzimadzi.Madzi oundana owuma, okhala ndi malo ocheperako -78.5 ° C, sali oyenera mphira wina wosatentha kwambiri, monga mphira wa silikoni.Nayitrogeni wamadzimadzi, wokhala ndi kutentha kwa -195.8 ° C, ndi woyenera pamitundu yonse ya rabala.Chachiwiri, chidebe chomwe chimasunga mbali zodulidwa zakonzedwa.Imasinthidwa kuchoka pa ng'oma yozungulira kupita ku lamba wonyamulira ngati chonyamulira.Izi zimathandiza kuti ziwalozo zigwere mu poyambira, kuchepetsa kwambiri kupezeka kwa mawanga akufa.Izi sizimangowonjezera luso komanso zimakulitsa kulondola kwa edging.Chachitatu, m'malo modalira kokha kugundana pakati pa zigawozo kuchotsa m'mphepete mwa ng'anjo, zofalitsa zophulika bwino zimayambitsidwa.Zitsulo kapena zolimba pulasitiki pellets ndi tinthu kukula 0.5 ~ 2mm amawomberedwa pamwamba pa zigawo pa liniya liwiro la 2555m/s, kupanga mphamvu zotsatira.Kusintha kumeneku kumafupikitsa kwambiri nthawi yozungulira.
(3) Makina achitatu a cryogenic deflashing
Wachitatu cryogenic deflashing makina ndi kusintha kutengera m'badwo wachiwiri.Chidebe chokonzera zigawozo chimasinthidwa kukhala dengu la magawo okhala ndi makoma obowola.Mabowowa amaphimba makoma a dengu ndi m'mimba mwake pafupifupi 5mm (akuluakulu kuposa awiri a projectiles) kuti ma projectiles adutse bwino m'mabowo ndikugweranso pamwamba pa zida kuti zigwiritsidwenso ntchito.Izi sizimangowonjezera mphamvu ya chidebecho komanso zimachepetsanso kuchuluka kwa zosungirako zomwe zimakhudzidwa (projectiles) .Zigawo za dengu sizimayikidwa molunjika mu makina ochepetsera, koma zimakhala ndi malingaliro ena (40 ° ~ 60 °).Ngongole yotengera iyi imapangitsa kuti dengu lisunthike mwamphamvu panthawi yowongolera chifukwa chophatikiza mphamvu ziwiri: imodzi ndi mphamvu yozungulira yomwe imaperekedwa ndi dengu lomwe likugwa, ndipo linalo ndi mphamvu yapakati yomwe imapangidwa ndi mphamvu ya projectile.Pamene mphamvu ziwirizi zikuphatikizidwa, kuyenda kwa 360 ° omnidirectional kumachitika, kulola kuti zigawozo zichotse m'mphepete mwa flash mofanana komanso kwathunthu kumbali zonse.
