Cov yeeb nkab kub-dip galvanized ua rau cov hlau melting ua rau cov hlau-raws li lub cev los tsim cov txheej txheej alloy, uas ua ke nrog cov substrate thiab txheej. 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 cov txheej txheej, muaj zog adhesion, thiab lub neej ua haujlwm ntev. Feem ntau ntawm North craftsmanship siv zinc-galvanized siv los yob zinc supplementation.

Thermally galvanized muaj qhov zoo ntawm cov txheej txheej, muaj zog adhesion, thiab lub neej ua haujlwm ntev. Cov yeeb nkab steel matrix thiab cov kua dej melting plated tshwm sim nyob rau hauv lub cev thiab tshuaj lom neeg cov tshuaj tiv thaiv, ua rau nruj zinc-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.
1. Lub uniformity ntawm galvanized txheej: cov qauv steel yeeb nkab yuav tsum tau immersed nyob rau hauv tooj liab sulfate tov 5 zaug nyob rau hauv ib tug nruam immersion (copper-plated xim)
2. Nto zoo: Qhov saum npoo ntawm galvanized steel kav yuav tsum muaj txheej txheej galvanized tiav. Yuav tsum tsis muaj qhov tsaus nti thiab npuas. Nws tso cai rau me me ntxhib qhov chaw thiab cov qog zinc hauv zos.
3. Dalvation txheej hnyav: Raws li cov kev xav tau ntawm tog neeg xav tau, galvanized steel kav tuaj yeem txiav txim siab raws li zinc txheej hnyav. Tus nqi nruab nrab yuav tsum tsis pub tsawg dua 500g / square meter, thiab ib qho qauv ntawm ib qho qauv yuav tsum tsis txhob tsawg dua 480g / square meter.
