Nws yog tsuas yog tsom rau cov kav dej steel, uas yog nquag mus rau corrosion, thiab muaj qee yam kev phom sij rau cov khoom puas tsuaj tom qab corrosion.Tom qab tshem tawm txhua yam roj, xeb, nplai, vuam chaw thiab lwm yam av, nws tuaj yeem txhim kho corrosion ntawm cov hlau.

Yog hais tias muaj av nyob ntawm qhov chawstainless hlau yeeb nkab, nws yuav tsum tau mechanically ntxuav thiab ces degreased.Lub xub ntiag ntawm roj nyob rau saum npoo yuav cuam tshuam qhov zoo ntawm pickling thiab passivation.Vim li no, degreasing tsis tuaj yeem raug tshem tawm.Koj tuaj yeem siv lye, emulsifiers, organic solvents thiab chav.

Passivation yog cov txheej txheem kawg hauv cov tshuaj ntxuav thiab yog cov kauj ruam tseem ceeb.Nws lub hom phiaj yog los tiv thaiv corrosion ntawm cov khoom.Piv txwv li, tom qab lub boiler yog pickled, ntxuav nrog dej, thiab rinsed, cov hlau nto yog huv si, heev activated, thiab yooj yim rau corrosion, yog li nws yuav tsum tau passivated tam sim ntawd los tsim ib tug tiv thaiv zaj duab xis nyob rau hauv cov hlau ntxuav kom huv si. corrosion.
