Lub hom phiaj ntawm Rinsing

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 cov kav hlau steel yuav tsum tau yaug 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 ntxuav tau 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 yaug yog qhov zoo dua, vim nws tuaj yeem tshem tawm qee qhov hydrogen los ntawm cov yeeb nkab steel substrate. Yog li, nws tuaj yeem pom tau tias kev yaug yog qhov tseem ceeb hauv kev txhim kho cov kav dej kub-dip galvanized steel kav.
