Kev siv tshuab cryogenic defiashing thawj zaug tau tsim nyob rau xyoo 1950. Hauv cov txheej txheem tsim cov tshuab cryogenic defiashing, nws tau dhau los ntawm peb lub sijhawm tseem ceeb. Ua raws li hauv tsab xov xwm no kom nkag siab tag nrho.
(1) Lub tshuab deflashing cryogenic thawj zaug
Lub nruas khov siv ua lub thawv ua haujlwm rau kev kho kom khov, thiab dej khov qhuav raug xaiv ua cov khoom txias. Cov khoom uas yuav kho tau raug thauj mus rau hauv lub nruas, tej zaum yuav ntxiv qee cov khoom siv ua haujlwm tsis sib haum. Qhov kub hauv lub nruas raug tswj kom mus txog qhov xwm txheej uas cov npoo tsis zoo thaum cov khoom nws tus kheej tseem tsis cuam tshuam. Yuav kom ua tiav lub hom phiaj no, qhov tuab ntawm cov npoo yuav tsum yog ≤0.15 hli. Lub nruas yog qhov tseem ceeb ntawm cov khoom siv thiab yog octagonal hauv cov duab. Qhov tseem ceeb yog tswj qhov cuam tshuam ntawm cov khoom siv tawm, tso cai rau kev ncig dov kom tshwm sim ntau zaus.
Lub nruas tig rov qab mus rau sab laug kom ntog, thiab tom qab ib lub sijhawm, cov npoo ntawm lub teeb ci ntsa iab ua rau tawg thiab cov txheej txheem ntawm kev txiav ua tiav. Qhov tsis zoo ntawm thawj tiam neeg khov kho yog kev txiav tsis tiav, tshwj xeeb tshaj yog cov npoo ntawm lub teeb ci uas seem ntawm qhov kawg ntawm kab sib cais. Qhov no yog tshwm sim los ntawm kev tsim pwm tsis zoo lossis cov roj hmab txheej tuab ntawm kab sib cais (ntau dua 0.2 hli).
(2) Lub tshuab deflashing cryogenic thib ob
Lub tshuab deflashing cryogenic thib ob tau ua peb qhov kev txhim kho raws li thawj tiam. Ua ntej, cov tub yees hloov mus ua kua nitrogen. Dej khov qhuav, nrog lub ntsiab lus sublimation ntawm -78.5 ° C, tsis haum rau qee cov roj hmab brittle kub qis, xws li roj hmab silicone. Kua nitrogen, nrog lub ntsiab lus boiling ntawm -195.8 ° C, yog haum rau txhua hom roj hmab. Qhov thib ob, kev txhim kho tau ua rau lub thawv uas tuav cov khoom yuav tsum tau txiav. Nws tau hloov los ntawm lub nruas tig mus rau lub thoob conveyor siv ua lub thawv. Qhov no tso cai rau cov khoom kom tig mus rau hauv qhov zawj, txo qhov tshwm sim ntawm cov chaw tuag. Qhov no tsis tsuas yog txhim kho kev ua haujlwm tab sis kuj txhim kho qhov tseeb ntawm kev txiav. Qhov thib peb, es tsis txhob cia siab rau kev sib tsoo ntawm cov khoom kom tshem tawm cov npoo flash, cov khoom siv blasting zoo-grained tau qhia. Hlau lossis yas tawv pellets nrog qhov loj me ntawm 0.5 ~ 2 hli raug tua rau ntawm qhov chaw ntawm qhov ceev linear ntawm 2555m / s, tsim kom muaj lub zog cuam tshuam loj heev. Qhov kev txhim kho no ua rau lub sijhawm voj voog luv dua.
(3) Lub tshuab deflashing cryogenic thib peb
Lub tshuab cryogenic deflashing thib peb yog kev txhim kho raws li tiam thib ob. Lub thawv rau cov khoom yuav tsum tau txiav tau hloov mus rau lub pob tawb khoom nrog phab ntsa perforated. Cov qhov no npog phab ntsa ntawm lub pob tawb nrog txoj kab uas hla ntawm kwv yees li 5 hli (loj dua txoj kab uas hla ntawm cov projectiles) kom cov projectiles hla dhau cov qhov du thiab poob rov qab mus rau saum toj ntawm cov khoom siv rau kev siv dua. Qhov no tsis yog tsuas yog nthuav dav lub peev xwm ua haujlwm ntawm lub thawv tab sis kuj txo qhov ntim cia ntawm cov khoom cuam tshuam (projectiles). Lub pob tawb khoom tsis tau tso ntsug hauv lub tshuab txiav, tab sis muaj qee qhov inclination (40 ° ~ 60 °). Lub kaum sab xis no ua rau lub pob tawb tig zog thaum lub sijhawm edging vim yog kev sib xyaw ua ke ntawm ob lub zog: ib qho yog lub zog tig los ntawm lub pob tawb nws tus kheej tumbling, thiab lwm qhov yog lub zog centrifugal tsim los ntawm qhov cuam tshuam projectile. Thaum ob lub zog no sib xyaw ua ke, kev txav mus los 360 ° omnidirectional tshwm sim, tso cai rau cov khoom kom tshem tawm cov npoo flash sib npaug thiab tag nrho hauv txhua qhov kev taw qhia.
