Hauv cov ntawv thov kev lag luam, muaj ntau hom steel kav. Ntawm lawv, kauv steel kav thiab stainless hlau kav yog ob hom. Lawv ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam, thiab lawv qhov sib txawv ntawm qhov chaw ua haujlwm yog qhov tseem ceeb cuam tshuam rau lawv cov kev ua tau zoo thiab kev siv.
Ua ntej, cia peb saib cov kev kho saum npoo ntawm cov kav dej stainless hlau. Kev kho saum npoo ntawm cov kav hlau stainless feem ntau suav nrog ob txheej txheem: kub dov thiab txias dov. Cov kav dej kub dov steel yuav ua kev kho cua sov thiab kev kho mob pickling. Cov txheej txheem no feem ntau yog siv rau hauv kev lag luam qhov tso tsheb hlau luam, cov khoom siv tshuaj lom neeg, thiab lwm yam. Nws cov tuab yog tuab, feem ntau ntawm 2.0mm-8.0mm. Tom qab txias dov stainless hlau kav, kev kho cua sov thiab pickling yuav tsum tau ua dua los ua kom lub ntsej muag qhia nyiaj-dawb luster. Txoj kev ua no ua rau cov khoom siv softer, haum rau kev sib sib zog nqus ua haujlwm, xws li cov khoom siv hauv tsheb thiab cov kav dej.
Ntawm qhov tod tes, kev kho saum npoo ntawm cov kav hlau kav tsuas yog tso siab rau cov cuab yeej xws li cov hlau txhuam txhuam los txhuam cov hlau kom tshem tawm xoob oxide, xeb, thiab welded slag. Txoj kev ua no yuav ncav cuag qhov sib txawv raws li xav tau. Piv txwv li, kev tshem tawm xeb ntawm tes tuaj yeem ncav cuag qib SA2, thiab lub zog tshem tawm tuaj yeem ncav cuag qib SA3. Yog hais tias daim tawv nqaij muaj zog hlau oxide txuas nrog lub ntsej muag ntawm cov hlau, xav tau ib txoj kev kho mob uas muaj zog dua.
Hauv kev kho saum npoo ntawm kauv hlau yeeb nkab, tshuaj tsuag (nthuav) tua xeb yog ib txoj hauv kev tseem ceeb. Txoj kev no tuaj yeem tsis tsuas yog nthuav tawm cov nyhuv adsorption lub cev ntawm lub raj zoo nkaus li, tab sis kuj txhim kho cov neeg kho tshuab adhesion nyhuv ntawm anticorrosive txheej thiab lub raj zoo li. Yog li ntawd, tshuaj tsuag (tshem tawm) xeb tshem tawm yog txoj kev zoo tshaj plaws ntawm xeb tshem tawm cov kav dej los tiv thaiv corrosion. Feem ntau hais lus, cov tshuaj tsuag (xuab zeb) tshem tawm feem ntau yog siv rau kev pov tseg ntawm sab hauv thiab sab nrauv ntawm lub raj, thiab xeb ntawm kev txhaj tshuaj blasting (xuab zeb) feem ntau yog siv rau kev pov tseg ntawm lub raj zoo li.
Raws li rau cov duab ntawm cov kauv steel yeeb nkab, nws kuj muaj nws tus kheej tshwj xeeb. Piv txwv li, cov plaub hau plaub hau, tsis tu ncua sib tsoo cov qauv sib tsoo cov khoom uas tsim nyog granularity polishing sasal bands, feem ntau yog siv nyob rau hauv lub tsev kho kom zoo nkauj, elevators, vaj tse, panels thiab lwm yam teb. Tsis tas li ntawd, qhov ci ntsa iab yog cov khoom tau los ntawm lub teeb pom kev zoo thiab ua kom tiaj tus tom qab txias dov. Nws nto gloss yog zoo heev thiab muaj ib tug siab reflectivity. Cov ntaub ntawv, thiab lwm yam.
Hauv cov ntsiab lus, kev ua tiav ntawm cov kav hlau kav thiab cov kav hlau tsis muaj steel muaj qhov sib txawv hauv kev ua, khoom siv, thiab lub hom phiaj. Cov kev sib txawv no ua rau lawv txhua tus muaj qhov ua tau zoo thiab siv tau, uas tuaj yeem ua tau raws li qhov xav tau ntawm ntau qhov chaw. Hauv kev siv tswv yim, peb yuav tsum xaiv cov yeeb nkab steel uas tsim nyog thiab txoj kev kho saum npoo raws li cov kev xav tau tshwj xeeb thiab cov xwm txheej.
