Txoj kev loj hlob ntawm Kub Dip Galvanized txheej ntau yam

1) Lead-free kub dip galvanized txheej
Lub paj zoo nkauj zinc yog cov yam ntxwv ntawm cov ntawv 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 txheem yuav cuam tshuam rau kev ua haujlwm, txheej txheej thiab corrosion tsis kam ntawm cov phaj txheej tom qab ua tiav, yog li cov thev naus laus zis ntawm zinc-dawb paj. me me zinc paj tau kawm txawv teb chaws txij li xyoo 1960. Los ntawm cov dej pos huab cua txias, Heurfey zinc 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 1980s, 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 cov txheej txheem galvanizing tsis muaj hlau lead, tsis muaj hlau lead-dawb galvanizing tau dhau los ua qhov kev txhim kho tam sim no ntawm kub galvanizing.
2) Kub galvanized phaj alloying txheej
Nyob rau hauv qhov kub-dip galvanized ntau yam, alloyed galvanized ntawv yog tsim los ntawm thermal diffusion kho tom qab plating. Kev tiv thaiv corrosion ntawm cov ntawv alloyed galvanized yog ntau tshaj ob npaug ntawm cov ntawv kub-dip galvanized zoo tib yam. Nyob rau tib lub sijhawm, cov evaporation ntawm zinc nyob rau hauv qhov chaw vuam yog txo, thiab qib ntawm zinc vapor pollution ntawm tooj liab electrode ntawm qhov chaw vuam tshuab yog txo, thiab lub neej ntawm cov electrode yog nce. Txhawm rau kom ntseeg tau qhov kev sib raug zoo ntawm cov hlau alloy galvanized phaj txheej, kev ntsuas cua sov thiab cua txias (kev ua haujlwm siab kub, lossis induction rhaub) yog siv rau cov tuab tuab alloy galvanized phaj rau lub tsheb sab nrauv phaj, thiab ntau hom alloying sensors tau nruab. los kho cov qauv sib xws hauv txheej txheej los ntawm kev ntsuas ntsuas thiab cov lus qhia hauv computer hauv lub sijhawm los tsim cov kev xav tau rau siab stamping deformation.
