Txo kev ntxhov siab thiab txhim kho qhov chaw
Los ntawm kev sib tsoo ntawm qhov chaw ua haujlwm nrog cov xuab zeb tua, kev ntxhov siab raug tshem tawm thiab lub zog saum npoo ntawm lub workpiece yog nce, xws li kev kho saum npoo ntawm lub workpiece xws li springs, machining cov cuab yeej thiab aircraft hniav.
Xuab zeb blasting tshuab ntxuav qib
Muaj ob tus neeg sawv cev thoob ntiaj teb rau kev huv huv: ib qho yog "SSPC-" tsim los ntawm Tebchaws Meskas hauv xyoo 1985; Qhov thib ob yog "Sa-" tsim los ntawm Sweden hauv 76, uas tau muab faib ua plaub qib, xws li Sa1, Sa2, Sa2.5 thiab Sa3, thiab yog tus qauv thoob ntiaj teb. Cov ntsiab lus yog raws li nram no:
Sa1 - sib npaug rau US SSPC - SP7. Siv cov txhuam hniav yooj yim, emery daim ntaub sib tsoo txoj kev, qhov no yog plaub yam kev huv huv yog nruab nrab, kev tiv thaiv ntawm cov txheej tsuas yog me ntsis zoo dua li cov workpiece tsis ua. Cov txheej txheem kev kho mob qib Sa1: qhov chaw ntawm lub workpiece yuav tsum tsis txhob pom cov roj, roj, residual oxide, xeb, residual xim thiab lwm yam av. Sa1 tseem hu ua Manual txhuam tu. (los yog tu chav kawm)
Sa2 qib - sib npaug rau US SSPC - SP6 qib. Kev siv cov xuab zeb blasting tu txoj kev, uas yog ib qho qis dua hauv kev kho sandblasting, uas yog, cov kev cai dav dav, tab sis kev tiv thaiv ntawm txheej tshaj li phau ntawv txhuam txhuam kom txhim kho ntau yam. Cov txheej txheem ntawm kev kho Sa2: lub workpiece nto yuav tsum tsis muaj roj, av, oxide, xeb, xim, oxide, corrosion, thiab lwm yam txawv teb chaws (tshwj tsis yog tsis xws luag), tab sis qhov tsis xws luag yuav tsum tsis txhob ntau tshaj 33% ntawm cov nto ib square. 'meter', nrog rau me ntsis ntxoov ntxoo; Ib qho me me ntawm cov xim me ntsis tshwm sim los ntawm qhov tsis xws luag lossis xeb; Oxide daim tawv nqaij thiab xim tsis xws luag. Yog hais tias muaj cov hniav nyob rau hauv thawj qhov chaw ntawm lub workpiece, me ntsis xeb thiab xim yuav nyob twj ywm rau hauv qab ntawm cov hniav. Sa2 qib tseem hu ua cov khoom tu khoom (lossis qib kev lag luam).
Sa2.5 - qhov no yog qib uas feem ntau siv hauv kev lag luam thiab tuaj yeem lees txais raws li kev xav tau thiab tus qauv. Sa2.5 kuj yog hu ua ze White cleanup (ze dawb los yog tawm ntawm dawb). Sa2.5 technical standard: tib yam li thawj feem ntawm Sa2, tab sis qhov tsis xws luag yog txwv tsis pub ntau tshaj 5% ntawm qhov chaw ib square meter, nrog rau cov duab ntxoov ntxoo me ntsis; Ib qho me me ntawm cov xim me ntsis tshwm sim los ntawm qhov tsis xws luag lossis xeb; Oxide daim tawv nqaij thiab xim tsis xws luag.
Chav Kawm Sa3 - Sib npaug rau US SSPC - SP5, yog chav kho mob siab dua hauv kev lag luam, tseem hu ua White Cleaning Class (lossis chav dawb). Sa3 qib kev ua qauv txheej txheem: tib yam li Sa2.5 qib, tab sis 5% duab ntxoov ntxoo, tsis xws luag, xeb thiab lwm yam yuav tsum muaj.
