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.
