Lub hom phiaj ntawm kev ntxuav yog dab tsi?

Tom qab tau khaws thiab tshem tawm ntawm lub tank pickling, cov kav hlau muaj cov kua qaub seem, hlau ntsev, thiab lwm yam khoom uas ua rau lawv qhov chaw. Cov tshuaj no ua rau muaj kev puas tsuaj rau kub-dip galvanizing, yog li nws yog ib qho tsim nyog yuav tsum tau ntxuav cov kav hlau tam sim ntawd hauv cov dej txias los yog dej kub. Raws li kev ntsuas cov ntaub ntawv, thaum sulfuric acid tov yog siv rau pickling, hlau ntsev cov ntsiab lus yog 7 grams ib square meter; Thaum siv cov tshuaj hydrochloric acid, cov ntsiab lus hlau ntsev yog 2.3 grams ib square meter. Yog tias kev ntxuav yog ua tiav tom qab pickling, qhov adhesion ntawm hlau ntsev ntawm qhov chaw ntawm cov yeeb nkab steel tuaj yeem raug txo mus rau 0 5-1 gram ib square meter. Tau kawg, kev siv dej kub rau kev ntxuav yog qhov zoo dua vim nws tuaj yeem tshem tawm ib feem ntawm cov roj hydrogen uas nyob hauv cov yeeb nkab steel matrix. Yog li, nws tuaj yeem pom tau tias kev ntxuav yog ib qho tseem ceeb hauv kev txhim kho qhov zoo ntawm cov kav dej kub-dip galvanized steel kav.
