Kev tsim cov deposits, deforming thiab yooj yim undesirable coatings ntawm ntau yam khoom thiab cov qauv, raws li txoj cai, tsis tau raws li qhov yuav tsum tau rau lawv cov kev ua tau zoo zog. Txoj kev tawm yog txoj kev ntawm kev ua, cov uas yog sib tsoo thiab polishing. Tab sis cov txheej txheem ntxuav saum npoo zoo li no yuav tsis zoo rau kev tshem tawm nplai, xeb, thiab qee zaum cov xim qub. Tsuas yog sandblasting ntawm qhov chaw, raws li cov hauv paus ntsiab lus ntawm kev ua abrasive, tuaj yeem tiv nrog qhov tshwm sim ntawm cov txheej txheem sib sib zog nqus deformation. Cov cuab yeej siv xuab zeb, uas ua raws li cov khoom siv tu. Txawm li cas los xij, lub hauv paus ntsiab lus ntawm kev ua haujlwm no tseem ua kom muaj kev nyab xeeb nruj thaum lub sijhawm ua haujlwm.

Sandblast phom

Muaj ob pawg ntawm cov cuab yeej zoo li no. Koj yuav tsum pib nrog qhib qauv. Raws li txoj cai, qhov no yog lub tshuab me me sandblasting, tus nqi ntawm qhov nruab nrab ntawm 3 mus rau 7 txhiab rubles. Los ntawm kev tsim, nws zoo ib yam li rab phom siv, siv los ntawm pneumatic. Cov khoom siv no tuaj yeem siv los ntxuav pob zeb, pob zeb thiab hlau los ntawm cov lauspleev xim, xeb, av, thiab lwm yam.

Qhov zoo ntawm rab phom suav nrog kev txav mus los, yooj yim ntawm kev siv thiab muaj peev xwm ua haujlwm kom raug nrog cov qauv ntawm cov duab nyuaj. Vim lub zog qis ntawm cov cuab yeej, sandblasting tsis xyaum ua puas lub hauv paus nto. Ntawm qhov tod tes, nws yog qhov siv tsis tau rau kev siv phom pneumatic rau qee hom kev ua haujlwm hauv kev cob qhia, yog li ntawd, cov khoom siv ntawm ib hom kaw yog siv.

Sandblasting chambers

Qhov no yog qeb thib ob ntawm cov khoom siv abrasive, kev ua haujlwm ntawm cov khoom siv sandblasting. Cov khoom siv no yog siv rau kev ua kom qhuav ntawm cov hlau qhov chaw txhawm rau txhawm rau tshem lawv cov xim qub, xeb, nplai thiab khawb. Raws li kev ua haujlwm crumb, electrocorundum lossis dej xuab zeb feem ntau yog siv - feem ntawm qhov nruab nrab nws txawv ntawm 0.1 txog 0.9 hli. Cov kev txwv tshwj xeeb ntawm cov abrasive yog txiav txim siab los ntawm cov dej num uas cov sandblaster yuav tsum ua. Tus nqi ntawm cov qauv no yog 15-20 txhiab rubles. Nyob rau tib lub sijhawm, kuj tseem muaj cov cuab yeej siv kim dua, uas yog tus yam ntxwv ntawm qhov loj me thiab, raws li, lub zog siab.

Sandblasting txoj cai

Thaum lub sijhawm ua haujlwm, lub tshuab coj lub dav hlau ntawm cov khoom abrasive mus rau saum npoo kom kho. Hauv cov khoom siv feem ntau, lub zog uas ua kom nrawm nrawm ntawm cov xuab zeb yog tsim los ntawm lub zog ntawm huab cua compressed. Ib qho qauv ntawm cov khoom siv zoo li no muablub xub ntiag ntawm peb lub ntsiab lus tseem ceeb, cov uas yog cov khoom siv dav hlau ncaj qha, compressor thiab abrasive hais. Nws kuj tseem yuav tsum tau nco ntsoov tias sandblasting tuaj yeem ua tau nrog ntau theem ntawm lub siab, uas yog, lub zog uas ua rau ntawm abrasive. Tus neeg teb xov tooj kho qhov ntsuas no, ua tiav cov txiaj ntsig zoo. Qhov tseeb yog tias qhov siab ntawm qhov siab tuaj yeem tsis tsuas yog tshem tawm cov txheej txheem ntxuav, tab sis kuj ua rau muaj kev puas tsuaj rau lub ntsiab ntawm qhov chaw. Yog li ntawd, tus neeg siv yuav tsum muaj qee yam kev txawj ntse thiab lub peev xwm los kho cov txheej txheem ua haujlwm.

Metal Cleaning Levels

Kev ntxuav cov hlau nplaum nrog cov khoom siv sandblasting yog suav tias yog feem ntau. Txog rau hnub tim, cov kev cai tshwj xeeb tau tsim rau qhov zoo ntawm qhov chaw, npaj rau kev ua haujlwm ntxiv. Nws yog tsim nyog tsom rau lawv yog hais tias sandblasting ntawm hlau lug nrog abrasives yog npaj. Yog li, GOST cov qauv qhia qhov txawv ntawm plaub theem ntawm kev ntxuav saum npoo los ntawm kev xeb thiab nplai:

• Nyob rau hauv tus txheej txheem ntawm kev tshuaj xyuas nyob rau hauv rau lub sij hawm magnification, xeb puas thiab teev tsis pom.
• Thaum pom qhov muag pom nrog lub qhov muag liab qab, nplai, cov nplais ntawm cov xuab zeb, cov cim ntawm corrosion, kub hnyiab thiab lwm yam khoom tsis yog xim hlau tsis pom.
• Txog li 5% ntawm thaj chaw pov tseg cuam tshuam los ntawm nplai thiab ntug stains pom ntawm qhov muag liab qab.
• Tsis muaj qhov pom tseeb ntawm kev xeb thiab flaking nplai ntawm cov khoom.

Kev nyab xeeb

Cov khoom siv tiv thaiv tus kheej yooj yim suav nrog lub kaus mom hlau, hnab looj tes thiab, yog tias tsim nyog, tag nrho. Nyob rau tib lub sijhawm, ntawm qhov chaw ua haujlwm uas tau ua tiav sandblasting, cov tsom iav tshwj xeeb rau lub kaus mom hlau yuav tsum tau muab yog tias lub teeb tseem ceeb puas lawm. Raws li rau cov cuab yeej nws tus kheej, nws yuav tsum tau grounded, txwv tsis pub yuav muaj kev pheej hmoo ntawm hluav taws xob poob siab. Niaj hnub no, ntau thiab ntau tus neeg siv khoom siv tsis tau paub tab tau ua tib zoo saib rau cov qauv tswj cov chaw taws teeb, ntseeg tias lawv muaj kev nyab xeeb dua thiab siv tau yooj yim dua. Tab sis qhov no tsis yog qhov tseeb kiag li, txij li kev tsim cov cuab yeej zoo li no muaj kev cuam tshuam ntau rau kev sib kis los ntawm cov abrasives thiab yuav tsum tau ua tib zoo saib xyuas.

Tseem khaws cov khoom siv ntawm qhov chaw. Tshwj xeeb tshaj yog tias koj yog sandblasting hlau, koj yuav tsum muaj roj hmab hose seals thiab nozzle rings ntawm tes. Yog tias tsim nyog, koj tuaj yeem hloov cov ntsiab lus no yam tsis tas yuav tsum tau ua haujlwm ua haujlwm.

Zaj lus

Qhov tsim ntawm corrosion ntawm qhov chaw ntawm lub tsheb lub cev ua rau ntau tus neeg tsav tsheb poob siab. Qhov no txhais tau tias koj yuav tau hu rau ib qho kev pabcuam tshwj xeeb thiab nteg tawm ib qho tseem ceeb rau kev kho. Tau kawg, muaj lwm txoj hauv kev los ntxuav cov hlau hauv daim ntawv ntawm cov ntawv xuab zeb thiab cov grinder, tab sis sandblasting yog qhov zoo dua thiab sai dua. Thiab qhov no siv tsis tau tsuas yog rau hlau, tab sis kuj rau pob zeb, raws li zoo raws li pob zeb khoom thiabcov vaj tse. Qhov tseem ceeb tshaj plaws yog xaiv cov qauv zoo ntawm sandblasting tshuab. Cov khoom siv pneumatic tau txais qhov nrov tshaj plaws. Ntawm tus nqi qis, lawv tau lees paub qhov kev pov tseg tag nrho ntawm cov txheej txheem tsis xav tau yam tsis muaj kev puas tsuaj rau cov qauv siv tau zoo.
