Niaj hnub no, cov kav dej kub-dip galvanized steel yog hom kev tswj hluav taws kub, thiab lawv tau ua tiav cov txiaj ntsig tsis tuaj yeem hloov pauv hauv kev lag luam hluav taws xob. Vim li cas ho tsis tuaj yeem hloov cov yeeb nkab kub-dip galvanized los ntawm cov kav hlau uas pheej yig dua lossis cov kav dej txias galvanized?
Lub thermal galvanized creation tau tsim nyob rau hauv nruab nrab -18th caug xyoo. Nws tau ua los ntawm txoj kev loj hlob ntawm cov txheej txheem kub-plating txheej txheem, thiab nws yog ntau tshaj 300 xyoo ntawm keeb kwm lub sij hawm. Txog rau hnub no, kub-dip galvanized tseem yog ib qho kev siv dav thiab kev ua haujlwm zoo hauv kev ntsuas steel.
Kub-dip galvanized yeeb nkab: Nws yog txheej txheej alloy uas ua rau cov hlau melting ua rau cov hlau-raws li lub cev, kom cov substrate thiab txheej yog ua ke. Kub-dip galvanized steel yeeb nkab yog siv los khaws cov yeeb nkab steel. Txhawm rau tshem tawm cov hlau oxide nyob rau saum npoo ntawm cov yeeb nkab steel, tom qab pickling, nws yog ntxuav nyob rau hauv ib tug tov aqueous tov zawj ntawm ammonium chloride los yog zinc chloride los yog ammonium chloride, thiab ces xa mus rau nws kub immersion zawj. Thermally galvanized muaj qhov zoo ntawm txheej txheej, muaj zog adhesion, thiab lub neej ua haujlwm ntev. Feem ntau ntawm North craftsmanship siv zinc-galvanized siv los yob zinc supplementation.
Kub-dip galvanized steel kav: Cov yeeb nkab steel matrix thiab melting plating kua muaj cov tshuaj lom neeg lub cev thiab tshuaj lom neeg, ua rau nruj zinc ib-hlau alloy txheej nrog corrosion kuj. Lub alloy txheej yog kev sib xyaw nrog zinc txheej thiab cov yeeb nkab steel matrix. Yog li ntawd, nws cov corrosion kuj muaj zog.
Txhawm rau txhim kho corrosion kuj ntawm cov yeeb nkab steel, galvanized steel yeeb nkab dav dav. Galvanized steel kav muab faib ua ob hom: kub-dip galvanized thiab electroplating. Qhov kub-dip galvanized thiab galvanized txheej yog tuab. Tus nqi ntawm electroplating yog tsawg, thiab qhov saum npoo tsis du heev. Oxygen vuam yeeb nkab: siv los ua steelmaking oxygen tshuab raj. Feem ntau, me me-caliber vuam steel yeeb nkab yog siv. Cov kev qhia tshwj xeeb yog yim hauv yim 3/8-2 ntiv tes. Nws yog ua los ntawm steel bands ntawm 08, 10, 15, 20 los yog 195-Q235. Rau corrosion, qee qhov yuav tsum tau nkag mus zoo.
Txheej txheem ntau lawm:
Galvanized siv → qhib yob → ncab → dov raj → vuam → caws pliav → passivation thiab yaug → zinc ntxiv → teeb tsa → typing logo → tailoring → ziab → phaus.
