Txawm li cas los xij, cov hlau tsis yog hlau txhua tus muaj ib yam: Lawv tsis xeb. … Qhov ntawd yog vim xeb yog hlau oxide. Txij li cov hlau tsis muaj hlau tsis muaj cov hlau tseem ceeb, tsis muaj hlau los ua hlau oxide, thiab yog li tsis muaj xeb tuaj yeem tshwm sim.
Yuav ua li cas cov hlau tsis yog hlau tuaj yeem ua rau tarnish?
Hmoov tsis zoo, cov hlau tsis muaj hlau, xws li tooj liab, tooj dag, thiab tooj liabyog qhov nrawm nrawm thaum raug huab cua.
Tus yam ntxwv ntawm cov hlau tsis muaj hlau yog dab tsi?
Cov khoom ntawm cov hlau tsis muaj hlau:
- High corrosion resistance.
- Yooj yim rau fabricate - machinability, casting, vuam thiab lwm yam.
- zoo thermal conductivity.
- Kev siv hluav taws xob zoo heev.
- Tsawg ntom (tsawg loj)
- Nyob zoo.
- Non-magnetic.
hom hlau twg tsis xeb?
Platinum, kub & nyiaj Knowing as the precious metals, platinum, kub thiab silver yog tag nrho cov hlau ntshiab, yog li lawv tsis muaj hlau thiab tsis tuaj yeem xeb. Platinum thiab kub yog qhov tsis tshua muaj tshwm sim, thiab txawm tias cov nyiaj tuaj yeem ua rau tarnish, nws yog qhov zoo rau corrosion-resistant thiab kuj pheej yig los ntawm kev sib piv.
Puas yog cov hlau ferrous muaj kev xeb thiab xeb?
Iron muaj cov khoom sib nqus vim tias nws cov electrons raug teeb tsa, yog li cov hlau uas muaj hlau yog hlau nplaum. Ferrous hlau kuj paub txog lawv nyiamxeb. Hlau yog feem ntau corrosion, tshwj xeeb tshaj yog thaum nws raug dej. Yog vim li cas ferrous hlau uas siv sab nraum zoov tuaj yeem tsim xeb sai sai.

Puas lub nkoj puas xeb xeb?
Zoo li ua rau muaj kev puas tsuaj rau txhua yam nyob ze, qhov tawg tawg tawg ua rau xeb txheej ua rau lub nkoj tawg dhau sijhawm, ua rau nws muaj oxygen ntau dua. Ntau lub Chuuk wrecks qhia tau hais tias muaj zog corrosion nyob rau hauv cov cheeb tsam uas dynamite nuv ntses tau tsoo tawm cov marine loj hlob thiab xeb.
Puas yog cov hlau tsis muaj hlau nplaum?
Feem ntau ntawm cov hlau tsis muaj steel hauv pawg no yog sib nqus. Yog tias muaj hlau, cov qauv siv lead ua ntawm martensitic stainless hlau tuaj yeem yog ferromagnetic. Vim hlau yog cov khoom tseem ceeb hauv cov hlau tsis muaj steel, martensitic steels muaj cov khoom sib nqus.
Puas yog cov hlau tsis muaj hlau dub?
Dub stainless hlau yog tib yam ntawm hlau, chromium, silicon, npib tsib xee thiab carbon uas ua rau cov khoom lag luam stainless hlau, tab sis nws muaj cov txheej txheem tiv thaiv ntawm polymer uas tsim dub matte tiav. Qhov txawv ntawm stainless hlau thiab dub stainless hlau yog dab tsi?
Yuav ua li cas yog cov hlau tsis muaj hlau nplaum?
