Stainless hlau muaj nws lub zog, qib siab hnyav, superior zog los tiv thaiv corrosion zog thiab tsis xeb zog. Yog li, nws yog siv rau hauv kev lag luam chemical, khoom noj khoom haus cav, tshuab hluav taws xob thiab hluav taws xob, kev tiv thaiv ib puag ncig hauv vaj tse, kev lag luam khoom vaj khoom tsev thiab tsev kho kom zoo nkauj, txoj kev lag luam, muab cov tib neeg zoo tshaj plaws ntawm noble thiab noble.
Daim ntawv thov kev lag luam ntawm cov tsis muaj zog steel fasteners yuav dhau los dav thiab dav, tab sis daim ntawv thov kev txhim kho ntawm cov hlau tsis muaj zog yuav txiav txim siab qhov kev txhim kho ntawm nws txoj kev kho cov tshuab hluav taws xob.
Stainless steel khawm siv feem ntau siv qhov kev kho deg ntu
Stainless hlau ntau yam
Feem ntau ntawm cov hlau tsis muaj hlau: feem ntau muaj cov xim zoo li cov xim xws li chromium (Cr), npib (Ni), molybdenum (Mo), thiab titanium (Ti).
Cov qauv uas tsis muaj qab hau: chromium stainless hlau, muaj Cr ≥ 12% los sis ntau dua; nickel-chromium stainless hlau, uas muaj Cr ≥ 18%, nrog Ni ≥ 12%.
Kev faib tawm los ntawm cov hlau tsis muaj hlau tsis muaj hlau: Muaj cov xeb hlau austenitic, piv txwv tias:
1Cr18Ni9Ti, 1Cr18Ni11Nb, Cr18Mn8Ni5. Martensitic stainless hlau, xws li: Cr17, Cr28 thiab hais txog. Feem ntau raug xa mus rau cov hlau tsis muaj hlau nplaum thiab hlau nplaum hlau.
Txoj kev tsis muaj hlau ntxeem hlau deg kho
Feem ntau siv stainless hlau deg kho tshuab muaj cov kev kho mob nram qab no:
1 nto xim xim xiav xim;
2 qhov rai iav pom kev;
3 npog xim.
Kev Xim Xim Tshuaj Kho Mob: Cov hlau tsis muaj xim nyob rau hauv cov txheej txheem ntawm kev ua, tom qab coiling, tying, vuam los yog khoom siv cua kub thiab cua sov, uas ua rau cov pa oxide dub. Qhov nyuaj ntawm grey-dub nplai no yog NiCr2O4 thiab NiF ob yam EO4, yav tas los siv hydrofluoric acid thiab nitric acid kom muaj zog tawm kev raug tshem tawm. Txawm li cas los xij, tus qauv no muaj nuj nqis, ua paug rau qhov chaw, tsim kev puas tsuaj rau tib neeg lub cev, thiab muaj corrosive heev thiab maj mam raug tshem tawm.
Tam sim no, nws muaj ob lub hom oxide tawv nqaij kho txoj kev:
(1) Sandblasting (Ntsiav tshuaj) Txoj Kev: Cov txheej txheem ntawm txau cov iav hlaws tawm me me yog siv los tshem tawm cov oxide dub nplai saum nplaim.
(2) Tshuaj siv: Siv cov tshuaj uas tsis yog-polluting pickling thiab non-toxic inorganic additives nyob rau hauv chav sov.
