Cov laj thawj rau nruj me ntsis tswj qhov kub ntawm chromate passivation daws

Thaum Galvanized steel kav hla kev kho mob passivation kev daws teeb meem, qhov kub ntawm cov kev txwv Yog hais tias qhov ntsuas kub ntawm cov kev daws teeb meem dhau los ua siab dhau, nws yuav nyuaj rau tsim cov yeeb yaj kiab passivation nyob rau saum npoo ntawm galvanized txheej. Txij li thaum passivation jacts tuaj yeem zom rau hauv dej kub, txawm tias ib zaj yeeb yaj kiab passivation, muaj qhov ntxim nyiam uas nws yuav yaj tag nrho. Yog li ntawd, thaum lub sij hawm kev kho mob hla dhau los, qhov ntsuas kub nyob hauv cov txheej txheem specifications yuav tsum tau ua kom nruj me ntsis rau kev tswj hwm.
