Tshuab polishing
Qhov no yog ib txoj hauv kev kom tau txais qhov kaj. Nws tuaj yeem tshem tawm cov oxide zaj duab xis, xeb me ntsis thiab qhov tsis sib xws ntawm S355J0WP los ntawm kev txiav thiab yas deformation ntawm cov khoom nto. Piv txwv li, siv cov cuab yeej polishing nrog cov khoom abrasive xws li oilstone strips, wool log thiab sandpaper, los yog ua los ntawm cov tshuab polishing tshwj xeeb. Txoj kev no tuaj yeem txo qhov roughness ntawm S355J0WP. Yog tias cov txheej txheem polishing raug tswj kom zoo, qhov roughness ntawm Ra tuaj yeem ncav cuag 0.3 - 3.0μm, uas qhia txog cov xim zoo nkauj ci ntsa iab. Nws yog tsim rau me me - batch los yog precision qhov chaw ua, tab sis phau ntawv ua hauj lwm yog tsawg npaum li cas, thiab nws yog ib qho yooj yim kom muaj uneven polishing rau loj workpieces.
Electrolytic polishing
Cov txheej txheem no yog qhov tsim nyog rau S355J0WP workpieces uas yuav tsum tau muaj qhov ci ntsa iab thiab zoo ib yam. Los ntawm kev noj S355J0WP workpiece ua lub anode thiab ib qho hlau insoluble li cathode, ob qho tib si yog immersed nyob rau hauv electrolytic cell. Thaum siv ncaj qha tam sim no, xaiv anodic dissolution tshwm sim ntawm qhov chaw ua haujlwm. Qhov no tuaj yeem tshem tawm me me protrusions ntawm qhov chaw, kom lub ntsej muag ci tau zoo tuaj. Cov nyhuv ci ntsa iab tom qab electrolytic polishing muaj cov yam ntxwv ntawm cov xim zoo ib yam sab hauv thiab sab nrauv thiab ntev - ntev luster. Tsis tas li ntawd, nws tsis cuam tshuam los ntawm qhov nyuaj ntawm S355J0WP, thiab tuaj yeem ua kom pom tseeb qhov tseeb ntawm cov khoom ua haujlwm, uas tsim nyog rau kev ua haujlwm loj ntawm cov khoom ua haujlwm nrog cov duab nyuaj.Bright kev kho cua sov
Kev kho cua sov ib txwm siv ntawm S355J0WP yog ib qho yooj yim ua rau oxidation nto thiab tsim ib txheej oxide, uas ua rau saum npoo tsaus. Txawm li cas los xij, kev kho cua sov ci tuaj yeem zam qhov teeb meem no. Los ntawm cua sov cov hlau nyob rau hauv lub tshuab nqus tsev vacuum los yog ib qho chaw tiv thaiv los ntawm inert gases (xws li argon, helium) los yog decomposed ammonia, lub nto oxidation thiab decarburization ntawm S355J0WP thaum lub sij hawm kho cua sov txheej txheem yog tiv thaiv. Tom qab kev kho mob, cov hlau yuav tsis tsim cov oxide txheej, thiab tuaj yeem tswj tau lub teeb xim hlau zoo nkauj. Cov txheej txheem no yog tshwj xeeb tshaj yog haum rau S355J0WP kav, nyias daim hlau thiab lwm yam khoom uas yuav tsum tau kom muaj qhov ci ntsa iab thaum txhim kho kev ua haujlwm sab hauv.
Tshuaj polishing + pickling thiab derusting
Ua ntej, nqa tawm Sa2.5 - qib txhaj tshuaj blasting lossis pickling kev kho mob ntawm S355J0WP kom tshem tawm cov txheej txheem oxide qub thiab xeb. Tom qab ntawd siv cov tshuaj polishing cov neeg ua haujlwm los ua cov kev xaiv sib cais ntawm qhov tsis sib xws ntawm qhov chaw. Qhov no tuaj yeem tshem tawm cov kab uas tshuav los ntawm cov txheej txheem derusting yav dhau los thiab theem saum npoo. Txoj kev no muaj qhov zoo ntawm cov khoom siv yooj yim thiab kev ua haujlwm siab, thiab tuaj yeem polish ntau yam haujlwm tib lub sijhawm. Nws yog haum rau loj - cheeb tsam S355J0WP cov khoom xws li lub tsev ntaub thaiv phab ntsa thiab choj accessories. Txawm li cas los xij, kev saib xyuas yuav tsum tau them rau kev kho cov kua khib nyiab thaum lub sijhawm ua kom tau raws li kev tiv thaiv ib puag ncig.
Ci txheej
Yog xav tau ntev - lub teeb ci ntsa iab yog xav tau thaum ua kom muaj kev tiv thaiv corrosion, lub teeb ci tuaj yeem siv rau ntawm S355J0WP. Tom qab qhov saum npoo yog derusted thiab polished, electrostatic hmoov txau yog siv los ua kom sib npaug ntawm cov hmoov ci qhuav ntawm cov hlau nto, thiab tom qab ntawd nws kho tau ntawm qhov kub thiab txias los tsim cov txheej ruaj khov thiab ci ntsa iab. Cov txheej txheem no tsis tsuas yog muaj lub ntsej muag ci, tab sis kuj tuaj yeem txhim kho corrosion kuj ntawm S355J0WP. Nws yog tsim rau cov chaw sab nraum zoov xws li cov paib txoj kev thiab cov vaj tsev kho kom zoo nkauj ua los ntawm S355J0WP.
