Stainless Hlau Ntawv - Qib 304
Kev piav txog
Corrosion tsis kam ntawm 304 daim ntawv hlau feem ntau yog nyob ntawm nws li alloy muaj pes tsawg leeg (chromium, thiab lwm yam) thiab siv chromium ua si lub luag haujlwm tseem ceeb tshaj plaws. Chromium muaj cov tshuaj ruaj khov ruaj khov, ua kom nws ua yeeb yaj kiab sib txawv, tiv thaiv cov hlau sab nraud, tiv thaiv cov hlau sib txawv, thiab txhim kho nws txoj kev txhim kho corrosion. Thaum cov zaj duab xis passive yog puas ntsoog, kev xeb tsis kam txo.

Qhov tseem ceeb ua ke:
Cov qauv teb chaws tau kho me ntsis rau chromium (CR) thiab npib tsib caug (NI). Piv txwv li, Tuam Tshoj yuav tsum muaj lub siab loj dua lossis muaj sib npaug rau 18% thiab ni ntau dua li 8%, thaum United States tso cai rau ib qho kev txwv qis ntawm 17.5% rau Kr.
Daim Ntawv Qhia Cov Khoom Noj-Qib:
Ua raws li GB 4806.9-2016 (Tuam Tshoj) lossis FDA (Tebchaws Asmeskas) yog qhov yuav tsum tau ua, nrog cov leeg tswj ntawm cov hlau hnyav. Cov khoom tsis yog tus qauv 304 tsis tuaj yeem hloov ncaj qha.

Nws ua rau corrosion tiv thaiv nitric acid (siab tsawg dua lossis sib npaug rau 65%), organic acids, thiab alkaline daws; Txawm li cas los xij, nyob rau hauv ib puag ncig nrog chloride ion siab tshaj 200 ppm, nws raug nquahu kom siv 316L stainless hlau dua.
Cov phiaj tau muab faib ua kub-dov thiab cov pawg txias-yob. Cov saum npoo muaj peev xwm kho tau nrog cov plaub hau teev lossis electrolytic polishing, thiab nws muaj cov tshuaj ntsuab zoo, thiab muaj zog kho tshuab. Nws tau thov rau hauv cov liaj teb xws li cov khoom siv petrochemical, cov kav dej, thiab lub tsev ua haujlwm facades (piv txwv li, lub pej thuam Shanghai).
