Thaum twg peb xaiv txhuas roj tshem tawm, yuav tsum xaiv cov roj kua remover, qaug zog alkaline, uas yuav tsis corrode lub txhuas. Nws zoo dua yog tias tsis muaj cov khoom tsis haum, tshwj xeeb tshaj yog sodium nitrite, sodium silicate, sodium metasilicate, sodium fluoride, sodium chloride, chromium oxidant thiab lwm yam tshuaj tsis muaj kab mob.
Xws li cov neeg tsis huv ferrous hlau tu tus neeg sawv cev, tus neeg sawv cev tshem roj tawm, tsis tuaj yeem xaiv tus neeg saib xyuas anticorrosion tus neeg saib xyuas tom qab tshem cov roj?
Raws li cov khoom siv txhuas txhuas yog cov khoom zoo nkauj. Nws tsis yog yooj yim kom tshem ntawm smeary hauv aluminium khoom, yog li ntawd peb yuav tsum xaiv tus neeg sawv cev ntawm kev sib tw uas tau faib cov roj muaj nuj nqi los yog oxidant, thaum ua cov xim tsis tshua muaj suab npe, tshem tawm cov kua nplaum nplaum. Xws li tus txha nqaj dej deev kis tus neeg sawv cev, tsis muaj dej kua chromium degreasing oxidation.
Cov txheej txheem kev txhim kho cov txheej txheem txhim kho corrosive primer yog dab tsi?
Nrog cov roj tshem tawm muaj nuj nqi.
Kev tiv thaiv ib puag ncig, tsis muaj chromium ions (nrog rau trivalent chromium) tsis muaj lwm yam hnyav hlau thiab muaj zog oxidants, xws li xee, tooj liab, txhuas, nitric acid thiab thiaj li.
Yuav siv tsis tau cov hluav taws xob uas muaj cov tshuaj tua kab mob uas ua rau muaj kev tiv thaiv kev tiv thaiv kev tiv thaiv, xws li ntsev, sodium benzoate, sodium nitrite, emulsified wax, roj emulsified thiab lwm yam.
Tom qab passivation, zaj duab xis yog tsis muaj xim. Nyob rau lub sij hawm yuav tsum tau, txhuas saum npoo yuav tsum tsis txhob tuaj yeem dawb xeb lossis dub xeb nqaij ntawd.
Yuav siv tsis tau kua qaub uas yuav ua rau muaj kev sib ceg nrog txhuas, xws li tshuaj fluoride.
Yog ntev li cov xwm txheej saum toj no tau ntsib, cov kua tshuaj ntawm lub tuam txhab yuav siv tau. Nws yog qhov zoo tshaj plaws los xaiv qhov ib puag ncig, qis-nqi thiab tshuaj siv hauv tsev-kub, thiab cov khoom tsim nyog tau xaiv thiab kuaj thiab soj ntsuam hauv online nug.
