Cov khoom siv
Thaum cov neeg yuav khoom xauv, lawv feem ntau txhawj xeeb txog qhov ntsuas phoo tsis ruaj khov lossis tsis ntev tom qab qhov saum npoo yuav xeb lossis oxidation.Qhov teeb meem no muaj feem xyuam rau cov khoom siv thiab kev kho deg.
Los ntawm qhov pom kev ruaj khov, cov khoom siv zoo tshaj plaws yuav tsum yog cov hlau tsis muaj steel, tshwj xeeb tshaj yog cov khoom siv saum npoo, siv ntau qhov ci.Nws lub zog, corrosion kuj, xim tsis hloov.Tab sis kuj tseem muaj ntau yam stainless hlau, feem ntau tuaj yeem muab faib ua ferrite thiab austenitic.Ferritic stainless hlau muaj hlau nplaum, feem ntau hu ua stainless hlau, lub sijhawm ntev, ib puag ncig tsis zoo yuav xeb, tsuas yog austenitic stainless hlau yuav tsis xeb, kev txheeb xyuas yog yooj yim heev, nrog cov hlau nplaum tuaj yeem txheeb xyuas.
Tooj tooj liab yog ib qho ntawm cov khoom siv kaw ntom nti, nrog cov khoom siv zoo, zoo corrosion kuj thiab cov khoom ua haujlwm, thiab cov xim ci, tshwj xeeb tshaj yog cov kov thiab lwm yam xauv qhov chaw ntawm tooj liab forging, du nto, zoo ntom, tsis muaj pores, sandholes.Twb khov rustproof, tuaj yeem siv plating 24K kub lossis txhua hom kev ua haujlwm xws li placer kub, zoo li zoo nkauj, siab thiab yooj yim, tsev neeg uas muab cov neeg ntxiv ntau xim.
Cov khoom siv zinc alloy, nws lub zog thiab xeb kuj yog qhov phem dua, tab sis nws qhov zoo dua yog yooj yim los ua cov qauv ntawm cov khoom, tshwj xeeb tshaj yog siab casting.Lub xauv uas qhov kev tsim ntau dua uas qhov chaw ua lag luam pom zoo li yuav yog zinc alloy ua tiav ntau heev, cov neeg siv khoom xav tau ceev faj sib txawv.
Hlau thiab hlau, lub zog zoo, tsis tshua muaj nqi, tab sis yooj yim rau xeb, feem ntau yog siv los ua cov khoom siv hauv cov khoom siv xauv, tsis yog cov khoom siv sab nrauv.
Aluminium los yog aluminium alloys, zoo tib yam aluminium alloys (tshwj tsis yog aerospace) yog mos thiab lub teeb, tsis tshua muaj zog tab sis yooj yim rau kev tsim.
