Technically, lub chaw tsim khoom ntawm stainless hlau dab dej feem ntau yog nyob ntawm cov txheej txheem xws li stamping, vuam, thiab polishing ntawm stainless hlau los xij. Stamping tso cai rau cov ntawv hlau stainless los tsim cov qauv ntawm lub dab dej, thaum vuam ua kom muaj kev sib txuas ntawm txhua qhov chaw. Thaum kawg, polishing muab lub dab dej stainless hlau du, ci zoo li, ua rau nws tsis tsuas yog ua kom zoo nkauj tab sis kuj yooj yim los ntxuav thiab tswj.
Txoj Cai Tiv Thaiv Corrosion thiab xeb ntawm Stainless Hlau Sinks
Chromium Oxide Passivation Film: Stainless hlau (tshwj xeeb tshaj yog 304 stainless hlau) muaj ntau dua los yog sib npaug rau 18% chromium. Nyob rau hauv cov huab cua, nws reacts nrog oxygen rau spontaneously tsim ib tug ntom, nws tus kheej - kho chromium oxide (Cr₂O₃) passivation zaj duab xis ntawm nws nto. Cov yeeb yaj kiab no zoo cais tawm cov xov xwm corrosive xws li ya raws, roj, thiab tsis muaj zog acids (xws li vinegar thiab kua txiv qaub) los ntawm kev sib cuag nrog cov hlau substrate, yog li tiv thaiv xeb.
Cov khoom sib txawv: 304 stainless hlau (muaj 8% ~ 10.5% npib tsib xee) muaj zog tiv taus pitting thiab kev ntxhov siab corrosion dua li 201 lossis 430 stainless hlau, ua rau nws tsim nyog rau qhov chaw ntub dej ntawm chav ua noj uas nquag ntxuav.
