Nyob rau hauv kev tsim cov kub-dip galvanized galvanized palvanized palvanized tau ua rau muaj kev mob siab rau txhuam ntawm zinc openulates ntawm tus Tsov tus tw kawg ntawm cov kav dej kawg. Thaum cov kav dej hlau thauj mus los hauv xov tooj cua kub, lawv pib dipped rau hauv da dej zinc ntawm lub taub hau, maj mam imprersing tus Tsov tus tw kawg. Qhov qauv no tso cai rau huab cua cov yeeb nkab thiab roj av tsim los ntawm cov tshuaj tiv thaiv flux (lossis molten flux) thiab zinc kom raug ntiab tawm ntawm tus Tsov tus tw kawg. Thiaj li, tus da dej zinc tuaj yeem nkag mus rau sab hauv ntawm cov yeeb nkab unobstructed, ua tiav cov txheej txheem galvanizing ntawm sab hauv phab ntsa. Raws li cov da dej zinc nkag mus rau cov yeeb nkab steel, cov yeeb ncuab zinc uas tsim los ntawm flux (lossis zinc flux) thiab zinc flux) thiab zinc flux) thiab zinc ntawm cov yeeb nkab sab hauv ntawm tus Tsov tus tw mus ua ke. Qhov no ua rau muaj qhov tseem ceeb ntawm zinc oxide pom ntawm cov zinc da dej ntawm tus Tsov tus tw kawg. Hauv kev sib piv, cov kab mob flux thiab cov tshuaj tiv thaiv kab mob flux (lossis zinc fluter ntawm tag nrho cov yeeb nkab ntawm cov yeeb nkab steel, ua rau lawv tshwm sim sib luag ntawm cov zinc da dej.
Tsis tas li ntawd, tom qab kev kho mob hlau, cov ntsev hlau thiab cov khoom siv hlau ua kom tiav rau sab hauv phab ntsa ntawm cov yeeb nkab sab hauv ntawm cov yeeb nkab hauv phab ntsa sab hauv cov yeeb nkab ntau dua li cov sab nraud. Tom qab thov flux (lossis molten flux), cov impurities yog nqa mus rau hauv lub dinc da dej. Cov khoom siv hlau ua rau muaj kev cuam tshuam nrog cov da dej zinc kom tsim zinc slag thiab flux residue. Cov zinc slag tog mus rau hauv qab ntawm cov da dej zinc, thaum cov roj carbon me me thiab flux residue ntab ua ke nrog zinc oxide (zno) nyob rau saum npoo zinc. Yog li ntawd, muaj ntau dua zinc oxide thiab lwm yam pov tseg ntawm cov npoo ntawm cov khaub ncaws zinc ntawm lub galvanizing steel dej dua li lwm qhov hauv cov laujkaub zinc.
Lwm qhov laj thawj yog vim li cas cov ntsiab lus txhuas ntawm zinc da dej nto hauv cov yeeb nkab steel yog qis dua li ntawm zinc da dej hauv kev sib cuag nrog sab nrauv. Qhov no ua rau txo qis lossis tsis tuaj yeem tiv thaiv alumina zaj duab xis, ua rau muaj kev tsim cov zinc oxide ntau ntxiv.
