Yuav ua li cas tiv thaiv corrosion ntawm hlau hoses, ua ntej ntawm tag nrho cov, cov hlau molecules react nrog cov CO2 nyob rau hauv cov huab cua thiab ces tsim ib tug oxidation zaj duab xis rau saum npoo. Lub compound tsim ntawm cov pa roj carbon zoo tib yam yog oxidized dua, uas ua rau cov xeb txhim kho tsis tu ncua, thiab thaum kawg ua rau qhov. Cov pa roj carbon steel nto tuaj yeem tiv thaiv los ntawm electroplating nrog cov xim lossis oxidation-resistant hlau molecules, thiab qhov kev saib xyuas no tsuas yog ib zaj duab xis nyias. Yog tias cov txheej tiv thaiv puas lawm, cov hlau hauv qab yuav maj mam xeb.
Kev tiv thaiv corrosion ntawm hlau hoses nyob ntawm cov chromium muaj pes tsawg leeg. Cov roj corrosion tsis kam ntawm cov hlau yog qhov pom tseeb, tab sis thaum muaj chromium muaj pes tsawg leeg, txawm hais tias qhov corrosion kuj tseem muaj, nws tsis tseem ceeb. Yog vim li cas yog tias thaum cov hlau yog nplua-grained nrog chromium, hom nickel hydroxide nyob rau saum npoo tau hloov mus rau cov nickel hydroxide ntawm cov khoom siv molecular ntawm cov hlau ntshiab chromium.
Qhov no zoo sib xws nickel hydroxide tswj qhov chaw thiab tiv thaiv oxidation ntxiv. Cov oxide txheej no yog nyias nyias, los ntawm qhov uas lub ntuj gloss ntawm stainless hlau nto tuaj yeem pom, ua rau cov hlau tsis muaj qhov tshwj xeeb.
Tsis tas li ntawd, yog tias qhov chaw puas lawm, cov hlau raug puas lawm yuav hnov mob nrog huab cua los kho nws tus kheej, ua rau cov phosphating zaj duab xis no dua, uas yuav tsum tau kho dua.
