Sandblasting vs Powder Txheej: Dab tsi yog qhov txawv?
Sandblasting thiab hmoov txheej yog ob txoj hauv kev siv hauv kev npaj nto thiab ua tiav ntawm ntau yam ntaub ntawv. Hauv tsab xov xwm no, peb yuav tshawb txog ob txoj hauv kev no kom ntxaws, suav nrog lawv cov txheej txheem, qhov zoo, thiab qhov tsis zoo.
Sandblasting
Sandblasting, tseem hu ua abrasive blasting, yog cov txheej txheem uas siv cov cua kub siab los yog dej los txhawb cov ntaub ntawv abrasive xws li xuab zeb, iav hlaws, lossis hlau tua rau saum npoo kom tshem tawm cov kab mob, xeb, lossis cov txheej qub. Cov txheej txheem feem ntau yog siv los npaj qhov chaw rau tha xim, txheej, lossis lwm yam txheej txheem tiav. Sandblasting yog ntau yam thiab siv tau zoo uas tuaj yeem siv rau ntau yam ntaub ntawv, suav nrog hlau, pob zeb, ntoo, thiab iav.
Cov txheej txheem sandblasting suav nrog kev siv lub tshuab sandblasting, uas txhawb nqa cov ntaub ntawv abrasive ntawm kev kub ceev mus rau qhov chaw kho. Cov khoom siv abrasive tshem tawm cov kab mob, xeb, lossis cov txheej txheem qub, tawm hauv qhov chaw huv thiab du uas npaj rau kev kho mob ntxiv. Muaj ntau hom khoom siv abrasive uas tuaj yeem siv rau hauv sandblasting, xws li xuab zeb, iav hlaws, hlau txhaj tshuaj, thiab txhuas oxide. Kev xaiv ntawm cov khoom siv abrasive nyob ntawm seb hom ntawm qhov chaw raug kho thiab qhov xav tau tiav.
Ib qho zoo ntawm sandblasting yog nws versatility. Nws tuaj yeem siv rau ntawm ntau yam ntaub ntawv thiab qhov chaw, nrog rau cov uas tsis zoo li qub lossis muaj cov geometry nyuaj. Sandblasting kuj yog ib txoj hauv kev zoo rau kev tshem tawm cov kab mob tsis zoo, xws li xeb lossis cov txheej qub, los ntawm qhov chaw. Tsis tas li ntawd, sandblasting tuaj yeem siv los tsim ntau yam ntawm qhov chaw tiav, los ntawm kev ntxhib los mos mus rau qhov chaw du, polished.
Txawm li cas los xij, kuj tseem muaj qee qhov tsis zoo rau sandblasting. Ib qho ntawm cov teeb meem tseem ceeb yog tias nws tuaj yeem cuam tshuam thiab siv sijhawm ntev. Cov khoom siv abrasive siv hauv sandblasting tuaj yeem tsim ntau cov plua plav thiab cov khib nyiab, uas tuaj yeem nyuaj rau kev ntxuav. Tsis tas li ntawd, sandblasting tuaj yeem yog cov txheej txheem nrov nrov, uas tuaj yeem ua rau muaj kev txhawj xeeb hauv qee qhov chaw.
Hmoov Txheej
Hmoov txheej, ntawm qhov tod tes, yog cov txheej txheem qhuav qhuav uas cuam tshuam nrog kev siv cov hmoov zoo rau saum npoo, uas yog tom qab ntawd ua kom sov los ua cov txheej txheem ruaj khov thiab ntxim nyiam. Hmoov txheej yog cov txheej txheem nrov tshaj plaws uas muab cov khoom siv ruaj khov thiab zoo nkauj rau ntau yam ntaub ntawv, suav nrog hlau, yas, thiab ntoo.
Cov txheej txheem hmoov txheej nrog rau daim ntawv thov ntawm cov hmoov zoo rau saum npoo raug kho, uas yog tom qab ntawd rhuab los ua cov txheej tawv tawv thiab ruaj khov. Cov hmoov feem ntau yog siv los ntawm cov tshuaj tua hluav taws xob electrostatic, uas tsub cov hmoov av thiab nyiam lawv mus rau qhov chaw kho. Thaum cov hmoov tau thov, qhov saum npoo yog rhuab rau hauv qhov cub, uas ua rau cov hmoov yaj thiab ua kom du, txawm tias txheej.
Ib qho zoo ntawm cov hmoov txheej yog nws cov kav ntev. Cov hmoov txheej muab cov khoom siv ruaj khov thiab ua kom ntev ntev dua li cov txheej txheem ua kua, vim nws tsis tshua muaj kev sib tsoo, fading, los yog tev. Tsis tas li ntawd, hmoov txheej yog ib puag ncig zoo dua li cov txheej txheem ua kua, vim nws tsim cov khoom pov tseg tsawg dua thiab tso tawm tsawg dua volatile organic compounds (VOCs).
Txawm li cas los xij, kuj muaj qee qhov tsis zoo rau cov hmoov txheej. Ib qho ntawm cov teeb meem tseem ceeb yog tias nws tuaj yeem ua tus txheej txheem kim dua li cov txheej txheem ua kua. Tsis tas li ntawd, hmoov txheej yuav tsum muaj cov cuab yeej tshwj xeeb thiab kev txawj ntse, uas tuaj yeem ua rau nws nyuaj rau kev ua haujlwm hauv tsev.
xaus
Hauv kev xaus, sandblasting thiab hmoov txheej yog ob txoj hauv kev siv hauv kev npaj thiab ua tiav ntawm ntau yam ntaub ntawv. Sandblasting yog ib txoj hauv kev zoo rau kev tshem tawm cov kab mob, xeb, lossis cov txheej qub los ntawm qhov chaw, thaum hmoov txheej muab cov khoom siv ruaj khov thiab zoo nkauj rau ntau yam khoom. Ob txoj kev muaj lawv qhov zoo thiab qhov tsis zoo, thiab qhov kev xaiv ntawm txoj kev nyob ntawm seb hom ntawm qhov chaw kho thiab qhov xav tau tiav.
