Cov laj thawj rau kev nquag tshwm sim ntawm ploj lawm galvanization sab hauv thiab ntawm qhov xaus ntawm galvanized steel kav

Cov kav hlau yog cov khoom siv galvanized nrog qhov sib txawv ntawm lawv qhov ntev thiab txoj kab uas hla. Tshwj xeeb, cov phab ntsa sab hauv ntawm cov kav hlau steel kuj xav tau cov zinc txheej, thiab cov xwm txheej sab hauv yog hnyav dua li cov nyob rau sab nrauv. Qhov no yog vim hais tias thaum lub sij hawm pickling kev kho mob, lub puab phab ntsa tsis tuaj yeem raug ntxuav kom huv si raws li cov phab ntsa sab nrauv, tawm hauv qab oxide nplai, uas tuaj yeem ua rau tsis muaj galvanization. Txawm hais tias cov phab ntsa sab hauv muaj tag nrho cov oxide scale tshem tawm los ntawm pickling, zoo li cov phab ntsa sab nrauv, tseem muaj lub caij nyoog rau cov hlau ntsev 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, kuj ua rau nco cov chaw galvanization. Thaum siv lub tshuab ziab khaub ncaws kom qhuav cov kav hlau, cov dej hauv sab hauv yuav khiav mus rau qhov kawg thaum rhuab. Vim yog lub tshav kub sai sai ntawm qhov kawg ntawm cov kav dej steel, qhov kub thiab txias yog qis dua, ua rau nws yooj yim rau ya raws rau condense muaj, diluting cov kuab tshuaj siv. Nyob rau tib lub sijhawm, immersing nrog noo noo mus rau hauv cov zinc da dej tuaj yeem ua rau "tawg" thiab ua rau cov kuab tshuaj puas, ua rau ploj galvanization. Thaum immersing nyob rau hauv zinc, ib kawg ntawm cov yeeb nkab steel yog dipped ua ntej, thiab tom qab ntawd lub inclination ntawm cov yeeb nkab steel yog maj mam txo kom txog thaum nws yog tag nrho submerged horizontally nyob rau hauv lub zinc da dej. Txoj kev ua haujlwm no tso cai rau zinc tshauv thiab noo noo hauv cov yeeb nkab steel bore kom du tawm. Yog tias lub kaum sab xis me me thiab ob qho kawg ntawm cov yeeb nkab steel yog muab tso rau 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 "tawg," ua rau. nco cov chaw galvanization. Phenomena xws li cov yeeb nkab steel dov ntawm zinc da dej nto kuj tuaj yeem ua rau muaj qhov tsis zoo ntawm cov galvanization hauv nruab nrab.
