Vim li cas thiaj muaj ntau qhov tsis zoo galvanizing hauv thiab qhov kawg ntawm galvanized steel kav?

Cov yeeb nkab steel yog txheej txheej nrog qhov sib txawv ntawm qhov sib txawv ntawm qhov ntev-rau-inch, tshwj xeeb tshaj yog thaum nws los txog rau galvanizing sab hauv phab ntsa ntawm cov yeeb nkab steel, qhov twg cov xwm txheej hnyav dua li cov nyob rau sab nrauv. Thaum lub sij hawm acid pickling, cov phab ntsa sab hauv tsis tuaj yeem ntxuav kom huv si zoo li cov phab ntsa sab nrauv, ua rau muaj cov hlau oxide nplai thiab tom qab tsis tau galvanizing. Txawm hais tias cov phab ntsa sab hauv yog ua tiav ntawm cov hlau oxide nplai zoo li cov phab ntsa sab nrauv, tseem muaj lub caij nyoog rau cov ntsev hlau kom ua raws li cov yeeb nkab phab ntsa, uas tsis tuaj yeem ntxuav los yog yaug tawm kom yooj yim li cov phab ntsa sab nrauv, ua rau tsis muaj galvanizing. chaw. Thaum siv lub qhov cub kom qhuav kom qhuav cov kav hlau, cov dej hauv sab hauv yuav khiav mus rau qhov kawg thaum cua sov. Vim yog lub tshav kub dissipation sai ntawm qhov kawg ntawm cov yeeb nkab steel, qhov kub muaj qis dua, ua rau nws yooj yim dua rau ya raws kom condense. Qhov no dilutes cov kuab tshuaj thiab ua rau nws puas vim cov dej noo nkag mus rau hauv zinc da dej, ua rau "popping" tshwm sim. Qhov no ua rau tsis muaj galvanizing. Thaum lub sij hawm zinc dipping, ib kawg ntawm cov yeeb nkab steel yog submerged ua ntej, thiab tom qab ntawd lub inclination ntawm cov yeeb nkab steel yog maj mam txo kom txog rau thaum nws yog tag nrho raus rau hauv zinc da dej horizontally. Qhov kev ua haujlwm no tso cai rau zinc tshauv, noo noo, thiab lwm yam impurities nyob rau hauv lub puab bore ntawm cov yeeb nkab steel yuav smoothly tawm. Yog tias lub kaum sab xis me me thiab ob qho kawg ntawm cov yeeb nkab steel yog submerged hauv zinc da dej ib txhij, zinc tshauv thiab noo noo hauv cov yeeb nkab steel tsis tuaj yeem tawm, uas tuaj yeem hlawv yooj yim los yog dilute cov kuab tshuaj thiab ua rau "popping," ua rau. nco galvanizing chaw. Phenomena xws li cov yeeb nkab steel dov ntawm zinc da dej saum npoo tuaj yeem ua rau tsis muaj galvanizing me ntsis hauv nruab nrab.
