Stainless hlauWelded kav yog hollow, elongated ncig stamp cov ntaub ntawv siv dav hauv kev lag luam xws li roj av, thiab kev noj qab haus huv, thiab kev noj qab haus huv. Tus neeg siv TikTok sau cov lus, "Puas muaj kev sib txuas ntawm daim ntawv thov stainless hlau welded kav thiab passivation?"
Thaum xaiv cov ntaub ntawv thiab kev tsim qauv rau cov qauv hlau uas siv rau hauv cov khoom siv sab hauv, kev ua kom haum rau kev cuam tshuam kev ntxhov siab thiab txo qhov cuam tshuam ntawm hluav taws xob.
Feem ntau, los txhim kho cov corrosion tsis kam ntawm cov hlau stainless welded kav, ob txoj hauv kev siv tau siv:passivation thiab electrolysisCov. Rau cov hlau stainless welded pipes thov kev tiv thaiv corrospe, siv cov txheej txheem passivation (siv cov hlau passivation daws). Hla yog tus txheej txheem tshiab ua lwm txoj hauv kev rau cov roj xeb xeb xeb. Lub hauv paus ntsiab lus cuam tshuam nrog kev daws teeb meem hauv cov kev daws teeb meem (stainless hlau passivation daws) los hloov cov hlau ions rau saum npoo av rau hauv lub xeev passive. Qhov no zoo pab qeeb hlau corrosion. Hla kev yog cov tshuaj tiv thaiv microchemical uas tsis hloov cov qauv molecular ntawm cov khoom. Nws tsuas yog muab cov pa oxygen nrog cov khoom siv hlau nyob hauv cov khoom siv, ua cov hlau oxide. Qhov no oxide txheej yog nyob rau hauv lub xeev passive, ua raws li kev thaiv ntawm cov hlau thiab txwv tsis ncaj rau cov hlau los ntawm kev ua kom muaj kev tiv thaiv corrosion.
Yog tshuaj lom neegtau txuas ntxiv thev naus laus zis, daws passivation (Stainless Hlau Passionation) thiab xeb tiv thaiv cov nyom rau cov neeg siv khoom. Peb muab cov khoom lag luam zoo, txiav cov khoom ntawm ntug thiab muab tag nrho cov teeb meem ntawm cov pej xeem cov kev xav tau ua kom tau raws li cov neeg siv khoom tshwj xeeb.
