Galvanizing, tseem hu ua kub ntsw thiab kub ntsw, yog txoj hauv kev zoo ntawm kev tiv thaiv kev tiv thaiv hlau, feem ntau yog siv hauv cov qauv hlau thiab cov chaw ntawm ntau yam lag luam. Nws yog txhawm rau txhuam cov hlau qhov chaw tom qab xeb tshem tawm mus rau qhov chaw siv tshuaj molten ntawm kua txog li ntawm 500 C, kom qhov chaw ntawm cov cheebtsam ntawm steel tau ua raws li zinc txheej, thiaj li ua tiav lub hom phiaj tiv thaiv xeb. Cov txheej txheem kub-dip galvanizing: cov khoom tiav tiav-pickling-ntxhua-ntxiv da dej-kom qhuav-dai galvanizing-txias-tshuaj-ntxuav-ntxuav-sib tsoo-kub-dip galvanizing. Kub-dip galvanizing yog tsim los ntawm cov txheej txheem qub ntawm kub-dip galvanizing. Nws muaj keeb kwm ntau dua 170 xyoo txij li daim ntawv thov kub-dip galvanizing hauv kev lag luam hauv Fabkis xyoo 1836. Hauv 30 lub xyoo dhau los, nrog kev txhim kho sai ntawm cov khaub thuas sib tw txias, kub-dip galvanizing kev lag luam tau tsim rau ntawm loj teev.
Kub dip galvanizing, tseem hu ua kub dip galvanizing, yog ib txoj hauv kev kom tau txais cov hlau txheej los ntawm kev siv hlau ua cov txheej txheem rau hauv molten zinc tov. Nrog txoj kev loj hlob sai ntawm kev siv hluav taws xob ntau ntawm cov xov hluav taws xob, kev thauj mus los thiab kev sib txuas lus, kev tiv thaiv kev tiv thaiv rau cov hlau thiab steel qhov chaw tau nce siab dua thiab ntau dua, thiab qhov kev thov rau kub-dip galvanizing kuj nce.
