Vim li cas cov kav hlau yuav tsum tau tiv thaiv corrosion?

Nyob rau hauv cov txheej txheem ntawm kev siv thiab thauj cov kav hlau steel raws li qhov nruab nrab (xws li roj, roj av, dej haus, thiab lwm yam), cuam tshuam los ntawm kev siv ib puag ncig thiab kev thauj mus los, cov kav hlau yuav raug tshuaj lom neeg lossis lwm yam laj thawj ua rau corrosion. thiab kev laus ntawm cov kav dej.

Yog li ntawd, txheej txheej yog los kho qhov chaw ntawm cov yeeb nkab steel nrog kev kho tshwj xeeb los tiv thaiv corrosion kom ua tiav lub hom phiaj ntawm kev nyab xeeb kev thauj mus los thiab ua kom lub neej ntev.
