Txoj kev loj hlob ntawm Kub Dip Galvanized txheej ntau yam

1) Lead-dawb kub dip galvanized txheej
Lub paj zoo nkauj zinc yog cov yam ntxwv ntawm cov ntawv kub kub galvanized, uas yog nyiam los ntawm cov neeg siv khoom thiab muaj qee yam khoom lag luam. Txawm li cas los xij, cov kev tshawb fawb tau pom tias qhov tsis sib xws ntawm cov paj zinc thiab cov ntsiab lus txhuas hauv cov txheej yuav cuam tshuam rau kev ua haujlwm, txheej txheej thiab corrosion tsis kam ntawm cov phaj txheej hauv kev ua tiav, yog li cov thev naus laus zis ntawm zinc- paj dawb thiab me me zinc paj tau kawm txawv teb chaws txij li xyoo 1960. Los ntawm cov dej pos huab cua txias, Heurfey zinc tshuaj tsuag thiab lwm yam txheej txheem, tus naj npawb ntawm cov siv lead ua nucleation tuaj yeem nce thiab siv lead ua kev loj hlob tuaj yeem tswj tau kom ua tiav lub hom phiaj ntawm kev tsim cov zinc paj me me. Txij li thaum xyoo 1980, cov teb chaws txawv teb chaws pib kawm cov hlau lead- dawb kub dipping zinc thev naus laus zis, Tebchaws Europe, South America cov kab tshiab galvanizing yog siv lead ua-dawb galvanizing txheej txheem, txhuas- dawb galvanizing tau dhau los ua qhov tam sim no txoj kev loj hlob ntawm kub galvanizing.
2) Kub galvanized phaj alloying txheej
Nyob rau hauv qhov kub-dip galvanized ntau yam, cov ntawv alloyed galvanized tau tsim los ntawm kev kho thermal diffusion tom qab plating. Qhov kev tiv thaiv corrosion ntawm cov ntawv alloyed galvanized yog ntau tshaj li ob npaug ntawm cov ntawv kub zoo tib yam -dip galvanized ntawv. Nyob rau tib lub sijhawm, cov evaporation ntawm zinc nyob rau hauv qhov chaw vuam yog txo, thiab qib ntawm zinc vapor kuab paug ntawm tooj liab electrode ntawm qhov chaw vuam tshuab yog txo, thiab lub neej ntawm cov electrode yog nce. Txhawm rau kom muaj kev sib raug zoo ntawm cov hlau galvanized phaj txheej, kev ntsuas cua sov thiab cua txias (kev ua haujlwm siab kub, los yog induction rhaub) yog siv rau cov tuab hlau alloy galvanized phaj rau lub tsheb sab nrauv phaj, thiab ntau hom alloying sensors tau nruab los kho cov qauv sib xws hauv txheej los ntawm kev ntsuas ntsuas thiab cov lus qhia hauv computer rau lub sij hawm siab los tsim cov kev xav tau.
