Kauv raj yog ib feem ntawm cov hlau cog tube, thiab ces rhuab nyob rau hauv lub nplhaib rauv-perforation-taw txoj kab uas hla-tsev kawm ntawv ncaj-txias-ua yeeb yam taub hau-packaging ua ib tug tsim nyog cov khoom tiav. Feem ntau Multi-spot, qhov no xav kom cov tswv lag luam tso qee cov khoom lag luam, tab sis cov tswv lag luam feem ntau tsis muaj cov tsev qiv ntawv loj hauv tsev. Feem ntau ntawm lawv yog cov tsev khaws khoom sab nraum zoov, thiab cov kav raj xaim yog qhov tsim nyog los khaws lub hnub.
Lub thiaj li hu ua xeb, raws li lub npe qhia, yog ib txheej ntawm xeb uas ntab mus rau lub kauv raj. Nws tuaj yeem raug tshem tawm nrog phuam lossis lwm yam. Yooj yim muab, xeb tsis yog xeb, uas yog qhov qub. Cov xeb ntawm cov kauv raj yog lub sijhawm ntev. Tsawg kawg yog ib xyoos yog ntau tshaj 1 xyoos, cov kav raj xaim hla cua thiab hnub raug, thiab cov rusty kauv raj muaj qhov loj thiab me me rau ntawm nws. Qhov txawv loj tshaj plaws.
Kauv raj xeb txoj kev tshem tawm
Cov tsos ntawm cov kuab tshuaj thiab emulsion tu steel yog siv los mus cuag cov kev tshem tawm ntawm cov roj, roj, plua plav, plua plav, smoothing tus neeg sawv cev thiab cov organic teeb meem zoo sib xws. Txawm li cas los xij, nws tsis tuaj yeem tshem tawm xeb, oxide, welded tshuaj, thiab lwm yam ntawm cov tsos ntawm cov hlau.
Lub dav hlau thiab xeb tshem tawm yog thim rov qab ntawm kev kub ceev ntawm kev txau cov hniav los ntawm lub zog siab zog, kom cov xuab zeb steel, cov tshuaj steel, cov xaim ntu, cov ntxhia thiab lwm yam abrasives yog txau thiab pov tseg cov yeeb nkab steel zoo li lub zog centrifugal. Thiab, nyob rau hauv cov nyhuv ntawm kev puas tsuaj thiab kev sib txhuam, cov yeeb nkab steel kuj tuaj yeem ncav cuag qhov nruab nrab roughness ntawm qhov xav tau.
Tom qab txau cov xeb tshem tawm, nws tuaj yeem tsis tsuas yog txuas lub cev adsorption nyhuv ntawm lub raj zoo nkaus li, tab sis kuj ntxiv dag zog rau cov neeg kho tshuab adhesion nyhuv ntawm anticorrosive txheej thiab cov tsos ntawm lub raj. Yog li ntawd, kev tshem tawm xeb yog txoj kev zoo tshaj plaws ntawm kev tiv thaiv corrosion ntawm cov kav dej. Feem ntau hais lus, kev tshem tawm xeb yog thawj zaug siv rau sab hauv thiab sab nrauv ntawm lub raj, thiab kev tshem tawm xeb ntawm cov tshuaj tua kab yog siv rau kev kho qhov chaw ntawm lub raj.
Cov cuab yeej tseem ceeb yog siv los txhuam cov tsos ntawm cov hlau hlau txhuam, thiab cov xoob lossis tsa oxide, xeb, thiab welded slag tuaj yeem raug tshem tawm. Yog hais tias cov tsos ntawm cov hlau txuas nrog cov tawv nqaij muaj zog hlau oxide, qhov kev tshem tawm cov xeb tsis zoo, thiab cov qauv thauj tog rau nkoj qhov tob ntawm cov kev tsim kho kev tiv thaiv tsis tuaj yeem ua tiav.
Ordinary chemistry thiab electrolytic txoj kev yog siv rau pickling thiab pov tseg. Lub raj xa dej anticorrosion tsuas yog tshuaj tua kab mob. Nws tuaj yeem tshem tawm oxide, xeb, thiab cov txheej qub. Qee zaum nws tuaj yeem siv los ua cov xuab zeb tshem tawm tom qab xeb tshem tawm. Txawm hais tias cov tshuaj tua kab mob tuaj yeem ncav cuag qhov kev huv huv thiab qhov tsis zoo ntawm qhov pom, nws cov qauv thauj tog rau nkoj yog ntiav, thiab nws yooj yim los tsim cov pa phem ntawm qhov xwm txheej. Qhov chaw xeb tshem tawm ntawm cov kauv steel yeeb nkab yog qhov tseem ceeb dua.
