Dab tsi yog sandblasting
Sandblasting, tseem hu ua abrasive blasting, yog ib txoj kev zoo heev ntawm kev tu, polishing, nto tiav, thiab engraving cov khoom. Cov txheej txheem no suav nrog kev quab yuam cov kwj ntawm cov khoom siv abrasive tiv thaiv qhov chaw nyob rau hauv siab siv compressed cua. Cov khoom siv abrasive siv rau sandblasting tuaj yeem muaj xws li xuab zeb, iav hlaws, rau txhuas oxide thiab silicon carbide.
Nws ua haujlwm li cas?
Lub tshuab sandblasting tshwj xeeb yog siv los txhawb cov khoom me me ntawm cov xuab zeb lossis lwm yam khoom siv abrasive ntawm kev kub ceev ntawm qhov chaw kho. Lub zog ntawm cov khoom siv los tsoo lub ntsej muag pab tshem tawm cov khoom tsis zoo xws li av, khib nyiab, xim, lossis xeb. Cov khoom lawv tus kheej yog me me uas lawv tsis ua rau muaj kev puas tsuaj rau qhov chaw raug kho, tab sis lawv muaj txiaj ntsig txaus los tshem tawm txawm tias tawv stains thiab buildups.
Cov ntaub ntawv dab tsi yog siv rau hauv nws?
Cov khoom siv feem ntau siv hauv sandblasting muaj xws li:
1. Xuab zeb - Xuab zeb yog cov khoom siv nrov tshaj plaws thiab siv dav hauv cov xuab zeb blasting. Nws yog pheej yig, yooj yim muaj, thiab zoo tshem tawm xeb, xim, thiab lwm yam impurities los ntawm hlau nto.
2. Cov hlaws iav - Cov hlaws iav yog tsim los ntawm cov iav zoo thiab siv rau kev npaj thiab ntxuav. Lawv yog qhov zoo tagnrho rau kev tu cov khoom siv me me, xws li cov dav hlau thiab cov khoom siv tsheb, qhov yuav tsum tau ua kom huv si.
3. Aluminium Oxide - Aluminium oxide yog cov khoom siv abrasive muaj zog uas siv los npaj thiab tshem tawm cov kab mob ntawm cov hlau. Nws kuj yog siv los tsim matte nto tiav los yog tshem tawm cov coatings.
4. Steel grit - Steel grit yog cov khoom siv abrasive ua los ntawm cov khoom siv hlau uas siv los tshem cov xeb thiab nplai ntawm cov hlau. Cov khoom siv abrasive no zoo tagnrho rau kev tu cov khoom hnyav, xws li cov khoom siv thiab cov cuab yeej siv.
Dab tsi yog nws qhov zoo thiab qhov tsis zoo
Cov hauv qab no yog qhov zoo ntawm sandblasting:
1. Ua tau zoo:
Sandblasting yog ib txoj hauv kev ceev thiab muaj txiaj ntsig ntawm kev ntxuav thiab tshem tawm xeb, xim, thiab lwm yam khoom paug. Nws yuav siv sij hawm tsawg dua li phau ntawv scraping, sanding, thiab hlau txhuam.
2. Ntau yam:
Sandblasting tuaj yeem siv rau ntau yam khoom xws li hlau, ntoo, yas, thiab pob zeb. Nws tuaj yeem tshem tawm cov txheej txheej txheej thaum khaws cia hauv qab.
3. Precise:
Sandblasting tuaj yeem tswj tau kom tshem tawm tsuas yog txheej txheej saum npoo uas xav tau, tawm hauv cov khoom siv tsis raug lossis tsis cuam tshuam.
4. Nqi-zoo:
Sandblasting muab cov txiaj ntsig ntev ntev, txo qis qhov xav tau ntxiv rau kev npaj los yog tu. Nws kuj yog tus nqi-zoo piv rau lwm txoj kev ntxuav.
Txawm tias muaj ntau qhov zoo, sandblasting kuj muaj kev txwv. Nov yog qee qhov tsis zoo ntawm sandblasting:
1. Kev pheej hmoo mob nkeeg:
Sandblasting ua rau cov plua plav thiab suab nrov uas tuaj yeem ua rau muaj kev phom sij rau tus neeg teb xov tooj kev noj qab haus huv. Yog li ntawd, cov iav kev ruaj ntseg yuav tsum hnav txhua lub sijhawm.
2. Kev cuam tshuam ib puag ncig:
Sandblasting tsim cov khoom pov tseg uas yuav tsum tau muab pov tseg kom zoo los tiv thaiv ib puag ncig.
3. Kev puas tsuaj saum npoo:
Sandblasting tuaj yeem ua rau qhov chaw puas yog tias tsis ua kom raug. Qhov chaw tsis sib xws thiab pitting yuav tshwm sim yog tias cov ntaub ntawv abrasive hnyav dhau.
Kev ceev faj thaum nws ua
Sandblasting yog ib qho txheej txheem siv los npaj cov chaw rau kev ua tiav lossis txheej. Nws suav nrog kev tua cov khoom me me ntawm cov ntaub ntawv abrasive ntawm qhov siab tshaj plaws kom tshem tawm cov kab mob los yog tsim kom muaj kev ntxhib los mos ntawm qhov chaw. Txhawm rau ua tiav cov txiaj ntsig zoo tshaj plaws, muaj qee yam yuav tsum xav txog thaum sandblasting.
Ua ntej, nws yog ib qho tseem ceeb los xaiv cov abrasives txoj cai. Cov ntaub ntawv sib txawv xav tau ntau hom khoom siv abrasive, thiab ib qho yuav tsum xyuas kom meej tias cov abrasives tau sib haum nrog qhov chaw raug blasted. Abrasives yuav tsum tau ua tib zoo xaiv raws li lawv cov hardness, qhov loj me, thiab cov duab los xyuas kom meej tias lawv tsis ua puas rau saum npoo thaum ua tiav cov nyhuv xav tau.
Qhov thib ob, kev nyab xeeb yuav tsum yog qhov tseem ceeb tshaj plaws thaum sandblasting. Cov txheej txheem tuaj yeem tsim ntau cov plua plav thiab cov khib nyiab uas tuaj yeem tsim kev puas tsuaj yog tias nqus tau. Cov neeg ua haujlwm yuav tsum siv cov iav tiv thaiv xws li lub tshuab ua pa, hnab looj tes, thiab tsom iav kom tsis txhob nqus cov khoom abrasive. Tsis tas li ntawd, thaj chaw ua haujlwm yuav tsum tau ua kom zoo-ventilated kom txo tau cov hmoov av.
Thirdly, cov cuab yeej siv yuav tsum tau ua kom zoo thiab tsis muaj qhov tsis xws luag. Cov cuab yeej blasting yuav tsum muab qhov sib npaug thiab txawm tias blasting siab los xyuas kom meej tias qhov chaw sib npaug. Kev saib xyuas tsis tu ncua thiab xyuas cov khoom siv yuav pab tiv thaiv cov teeb meem uas tuaj yeem cuam tshuam qhov zoo ntawm cov khoom tiav.
