Stainless hlau muaj ntau yam khoom uas ua rau nws txaus nyiam rau ntau yam kev siv, tab sis cov khoom qub no tuaj yeem ua rau nws nyuaj rau kev ua haujlwm nrog.Thaum siv, nws yooj yim khawb thiab av, ua rau nws yooj yim rau corrosion.Qhov kawg tab sis tsis kawg, nws yog kim dua cov pa roj carbon steel, yog li cov khoom siv nqi teeb meem yog exacerbated thaum stainless hlau qhov chaw tsim.
Cov neeg siv khoom kuj muaj kev cia siab siab rau qhov zoo ntawm qhov tiav, xav tau yuav luag daim iav zoo li tiav rau cov khoom siv uas los ntawm nws qhov xwm txheej yuav nthuav tawm raws li cov khoom tiav.Muaj tsawg heev ntawm kev zais qhov yuam kev nrog txheej lossis xim.
Thaum ua hauj lwm nrog stainless hlau kav, cov teeb meem no exacerbated mus rau ib tug tej yam, vim hais tias cov kev xaiv ntawm kev pom thiab zoo cov cuab yeej rau cov khoom siv yooj yim ua kom tiav yog txwv.
Vim nws cov corrosion kuj, stainless hlau yog zoo tagnrho rau daim ntaub ntawv uas yuav tsum tau lub ntuj sheen ntawm cov hlau, xws li lub kauj log thiab armrests.Qhov no kuj txhais tau hais tias sab nraud txoj kab uas hla ntawm lub raj yuav txawv ntawm frosted mus rau ib tug du, flawless tsos.
Qhov no yuav tsum muaj cov cuab yeej zoo ua ke nrog txoj cai abrasive.Feem ntau thawj lo lus nug peb nug peb cov neeg siv khoom yog dab tsi peev lawv txaus siab los ua kom ntseeg tau tias lawv tau txais cov yeeb nkab uas xav tau kom tiav sai thiab tsis tu ncua.Rau cov neeg uas xav ua kom tsis tu ncua ntawm cov yeeb nkab tiav kev txiav txim, automating cov txheej txheem nrog ib tug centerless grinder, cylindrical grinder, los yog lwm yam hom siv lub tshuab yuav yeej ua rau nws yooj yim mus txheeb qhov chaw kom ua tau raws li qhov xav tau.Cov khoom tiav tiav tuaj yeem ua tiav los ntawm ib feem mus rau ib feem.
Txawm li cas los xij, tseem muaj kev xaiv rau cov cuab yeej siv tes.Nyob ntawm qhov loj ntawm cov yeeb nkab, siv txoj siv hlua tuaj yeem yog txoj hauv kev zoo los xyuas kom meej tias qhov geometry tsis hloov thaum lub sijhawm ua tiav.Kev siv txoj hlua slack tso cai rau cov tubular profile ua haujlwm yam tsis muaj flattening.Qee txoj siv tawv muaj peb lub tsho sib tiv tauj, tso cai rau kom yooj yim dua nyob ib puag ncig lub raj.Belts muaj nyob rau hauv ntau qhov ntau thiab tsawg.Cov ntaub ntawv bands muaj li ntawm 18 "mus rau 24", thaum King-Boa xav tau 60 "mus rau 90" bands.Centerless thiab cylindrical siv yuav ua tau 132 nti ntev los yog ntev dua thiab mus txog 6 nti dav.
Qhov teeb meem nrog cov cuab yeej siv tes yog tias tau txais kev ua tiav zoo dua thiab ntau dua yog kev kos duab ntau dua li kev tshawb fawb.Cov neeg ua haujlwm paub txog tuaj yeem ua tiav kev ua tiav zoo nrog cov txheej txheem no, tab sis nws yuav siv sij hawm xyaum.Feem ntau, kev nrawm dua ua rau cov khawb me me, thaum qis qis ua rau khawb tob dua.Nrhiav qhov sib npaug rau ib txoj haujlwm tshwj xeeb yog nyob ntawm tus neeg teb xov tooj.Qhov pom zoo daim kab xev pib nrawm nyob ntawm qhov xav tau kawg taw tes.
Txawm li cas los xij, nws yog ib qho tseem ceeb kom tsis txhob siv cov disc lossis tes grinders ntawm txhua yam rau kev ua cov kav dej.Nws yog ib qho nyuaj kom tau txais cov qauv uas koj xav tau nrog cov cuab yeej no, thiab yog tias koj thawb lub dial nyuaj heev, nws tuaj yeem cuam tshuam cov duab geometry thiab tsim ib qho chaw tiaj tus ntawm cov yeeb nkab.Nyob rau sab xis, yog tias lub hom phiaj yog polishing daim iav saum npoo es tsis yog cov qauv kos, ntau cov kauj ruam sanding yuav siv thiab cov kauj ruam kawg yuav yog polishing compound lossis polishing stick.
Kev xaiv ntawm abrasive yuav tsum muaj kev nkag siab meej txog qhov kawg tiav.Tau kawg, qhov no yog yooj yim hais dua li ua.Kev tshuaj xyuas qhov muag feem ntau yog siv los ua kom sib haum nrog cov khoom uas twb muaj lawm.Txawm li cas los xij, lub khw muag khoom abrasive tuaj yeem pab txiav txim siab seb yuav ua li cas thiaj li yuav maj mam txo tus nqi ntawm abrasive kom ua tiav qhov xav tau.
Thaum sib tsoo stainless hlau mus rau qhov kawg nto, nws yog ib qho tseem ceeb uas yuav tau siv cov txheej txheem abrasive stepwise.Thaum pib, koj xav kom paub tseeb tias tag nrho cov stains thiab dents raug tshem tawm.Peb xav pib nrog cov khoom zoo tshaj plaws los daws cov teeb meem no;qhov tob qhov khawb, qhov ntau yuav tsum tau ua hauj lwm los kho nws.Ntawm txhua kauj ruam tom ntej, yuav tsum tau saib xyuas kom tshem tawm cov khawb los ntawm cov abrasive yav dhau los.Yog li, ib qho qauv kos tsis sib xws yog ua tiav ntawm cov khoom tiav.
Nrog cov tsoos coated abrasives, nws tuaj yeem nyuaj hla cov qib ntawm abrasive kom tau qhov zoo matte tiav ntawm stainless hlau vim txoj kev abrasive tawg.Txawm li cas los xij, qee qhov thev naus laus zis tso cai rau koj hla cov kauj ruam, xws li 3M's Trizact abrasives, uas hnav zoo li qhov abrasive yog "refreshed" nrog cov nplej tshiab thaum nws siv.3 M
Ntawm chav kawm, kev txiav txim siab txog qib ntawm roughness ntawm abrasive yog nyob ntawm cov khoom siv.Yog tias koj xav tau tshem tawm qhov tsis xws luag xws li nplai, dents lossis khawb tob, koj yuav tsum tau siv cov coarse abrasive.Piv txwv li, peb feem ntau pib nrog 3M 984F lossis 947A conveyor siv.Thaum peb tsiv mus rau 80 grit siv, peb hloov mus rau cov siv tshwj xeeb.
Thaum siv cov tsoos coated abrasives, nco ntsoov txo qhov gradation ntawm txhua qhov abrasive yam tsis tau ploj nws vim li cas cov abrasive tawg kom tau qhov tseeb matte tiav ntawm stainless hlau.Thaum cov abrasive tawg, ntau lub siab yuav tsum ua kom tiav tib yam li cov zaub mov tsaus lossis raug tshem tawm ntawm cov abrasive.Matte minerals los yog siab zog ua kom sov.Vim tias cov cua sov yog ib qho teeb meem thaum ua tiav cov hlau tsis huv, nws tuaj yeem cuam tshuam qhov kawg thiab "xiav" saum npoo.
Lwm qhov teeb meem uas tuaj yeem tshwm sim nrog qee qhov pheej yig abrasives yog qhov sib xws ntawm lawv cov ntxhia ua tiav.Nws yuav nyuaj rau tus neeg teb xov tooj uas tsis muaj kev paub los xyuas kom meej tias cov abrasive tau txais qhov xav tau ntawm txhua kauj ruam.Yog tias muaj qhov tsis sib xws, cov khawb tsiaj qus tuaj yeem tshwm sim uas yuav tsis pom mus txog rau theem polishing.
Txawm li cas los xij, qee txoj kev tso cai rau koj hla cov kauj ruam.Piv txwv li, 3M's Trizact Abrasive siv cov khoom sib tov ntawm cov cob thiab cov abrasive los tsim cov qauv pyramidal uas rov ua dua tshiab ntawm cov khoom tawg nrog cov khoom tshiab tshiab txawm tias cov abrasive hnav.Cov cuab yeej no ua kom muaj qhov ua tiav zoo ib yam thoob plaws lub neej ntawm txoj siv.Vim tias txhua qib ntawm Trizact daim kab xev muab qhov ua tiav tiav, peb tuaj yeem hla cov qib abrasive hauv qhov kawg ua tiav.Qhov no txuag lub sij hawm los ntawm kev txo cov kauj ruam sanding thiab txo cov rework vim tsis tiav sanding.
Tus yuam sij rau kev xaiv ib qho abrasive yog txiav txim siab yuav ua li cas kom tau qhov zoo tshaj plaws nyob rau hauv lub sij hawm thiab nqi npaum li cas.
Txij li cov hlau tsis muaj steel yog cov khoom siv tawv, kev xaiv ntawm abrasive thiab cov zaub mov tseem ceeb heev.Thaum siv cov abrasive tsis ncaj ncees lawm, qhov ntev ntawm cov khoom ua tiav, qhov kub ntau yog generated.Nws yog ib qho tseem ceeb uas yuav tsum tau siv hom pob zeb hauv av kom raug thiab siv cov abrasive nrog lub tshav kub dissipative txheej kom tshem tawm cov cua sov ntawm qhov chaw sib cuag thaum xuab zeb.
Yog tias koj siv lub tshuab, koj tuaj yeem siv lub tshuab ua kom txias, uas tseem yuav pab tshem tawm cov khib nyiab, kom ntseeg tau tias cov khib nyiab khawb tsis ua rau qhov chaw puas.Nco ntsoov siv cov lim kom raug kom cov khib nyiab tsis rov nkag mus thaum lub tshuab ua kom txias dua hauv lub tshuab.
Cov neeg feem coob xav tias tag nrho cov hlau tsis zoo zoo ib yam, tab sis thaum nws los txog rau qhov ua tiav ntawm ib feem, ob hom minerals tuaj yeem cuam tshuam qhov zoo ntawm qhov ntawd.Qhov kev pom no yog nyob ntawm tus neeg siv.
Piv txwv li, cov tsoos silicon carbide nyiam tawm qhov khawb ntxaum uas cuam tshuam lub teeb sib txawv thiab ua rau nws xiav.
Nyob rau tib lub sijhawm, tsoos aluminium oxide tawm ib lub voj voog ntau dua uas qhia txog lub teeb sib txawv thiab ua rau cov khoom daj.
Nyob ntawm qhov loj ntawm cov yeeb nkab, siv txoj siv hlua tuaj yeem yog txoj hauv kev zoo los xyuas kom meej tias qhov geometry tsis hloov thaum lub sijhawm ua tiav.Kev siv txoj hlua slack tso cai rau cov tubular profile ua haujlwm yam tsis muaj flattening.3 M
Paub txog qhov yuav tsum tau ua tiav ntawm ib feem yog qhov tseem ceeb vim tias cov ntawv thov feem ntau xav tau qhov tshiab kom phim cov uas twb muaj lawm.
Stainless hlau yog cov khoom kim heev, yog li ceev faj xaiv cov cuab yeej ua tiav yog qhov tseem ceeb.Kev txhawb nqa zoo los ntawm cov neeg muag khoom tuaj yeem pab cov khw muag khoom nrhiav txoj hauv kev kom txuag tau sijhawm thiab nyiaj txiag.
