Stainless hlau muaj cov yam ntxwv zoo xws li tsis muaj zog, tsis kam hnav siab, superior corrosion kuj thiab tiv taus xeb. Yog li, nws yog dav siv hauv kev lag luam chemical, khoom noj khoom haus tshuab, kev lag luam electromechanical, kev lag luam khoom siv hauv tsev thiab kho kom zoo nkauj hauv tsev, kev lag luam ua tiav.
Cov ntawv thov thiab kev txhim kho kev cia siab ntawm cov hlau tsis huv yuav ua dav thiab dav dua, tab sis daim ntawv thov thiab kev loj hlob ntawm stainless hlau lom zem ntau txiav txim siab qhov degree ntawm kev txhim kho ntawm nws cov txheej txheem kho tshuab.
Cov hom niaj seem ntawm cov hlaus tsis xeb hlau
1. Stainless hlau ntau yam
(1) Lub hauv paus tseem ceeb ntawm stainless hlau: feem ntau muaj cov khoom muaj hlau zoo xws li chromium (Cr), npib tsib xee (Ni), molybdenum (Mo), thiab titanium (Ti).
(2) Cov hlau tsis muaj hlau: chromium stainless hlau, muaj Cr≥12%; npib tsib xee-chromium stainless hlau, muaj Cr≥18%, muaj Ni≥12%.
(3) Kev faib tawm los ntawm cov qauv siv hlau tsis huv: steel muaj austenitic stainless hlau, xws li: 1Cr18Ni9Ti, 1Cr18Ni11Nb, Cr18Mn8Ni5. Martensitic stainless hlau, xws li: Cr17, Cr28, thiab lwm yam. Feem ntau hu ua cov hlau tsis muaj hlau thiab cov hlau nplaum stainless.
Feem ntau siv cov txheej txheem kev kho deg hlau stainless muaj cov kev kho hauv qab no:
1. Ntxuav hniav zoo nkauj ntawm lub ntuj xim;
2. Cov npoo iav ci ci kho;
3. Cov xim pleev xim sab hauv. Hauv kev tsim cov txheej txheem tsis xeb hlau nrog kev kho cov nplaim hluavtaws dub, nplai oxide dub yog tsim tom qab coiling, khi, vuam lossis khoom tsim kho cua kub. Qhov nyuaj grey-black oxide nplai yog tsuas yog tsim los ntawm NiCr2O4 thiab NiF, ob lub EO4. Yav dhau los, hydrofluoric acid thiab nitric acid feem ntau siv rau kev xeb muaj zog. Txawm li cas los xij, tus qauv no muaj nuj nqis, muaj kuab paug ib puag ncig, muaj teeb meem rau tib neeg lub cev, thiab muaj xeb ntau, thiab tau maj mam tshem tawm. Tam sim no, tsuas yog ob txoj kev kho oxide nplai kev ua haujlwm: ⑴ Sandblasting (ntsiav tshuaj) txoj kev: feem ntau siv cov txheej txheem kev txau micro iav hlaws dai kom tshem cov xim dub oxide rau saum npoo. Method Kev siv tshuaj lom neeg: Siv cov kuab paug tsis muaj kuab paug ntawm lub cev thiab cov tshuaj lom uas muaj tshuaj lom rau hauv lub cev kom sov. Txhawm rau kom ua tiav lub hom phiaj ntawm kev saib xyuas tawv dawb ntawm lub ntuj xim ntawm stainless hlau. Tom qab ua tiav, nws ib txwm zoo li xim xim npub. Txoj kev no zoo dua rau cov khoom loj thiab ntau. Raws li kev sib txawv ntawm cov khoom lag luam stainless hlau thiab kev sib txawv ntawm cov neeg siv, daim iav-ci kev kho cov txheej txheem ntawm stainless hlau saum npoo tuaj yeem ua tiav los ntawm kev kho tshuab polishing, tshuaj polishing, electrochemical polishing thiab lwm txoj hauv kev kom ua tau daim iav ci.
