Thaum nrhiav ib tug hloov raunichrome hlau, nws yog ib qho tseem ceeb uas yuav tau xav txog cov khoom tseem ceeb uas ua rau nichrome indispensable: high-temperature resistance, zoo ib yam hluav taws xob resistivity, corrosion kuj, thiab durability. Thaum ntau cov ntaub ntawv los ze, tsis muaj qhov sib npaug ntawm nichrome qhov sib npaug ntawm kev ua tau zoo-ua rau peb cov khoom siv nichrome hlau yog qhov kev xaiv zoo rau cov ntawv thov tseem ceeb.
Ib qho kev xaiv yog kanthal hlau, ibhlau-chromium-aluminium alloy. Kanthal ua tau zoo nyob rau hauv qhov chaw kub kub, tiv taus qhov kub thiab txias txog li 1,400 ° C, uas siab dua qee qib nichrome. Txawm li cas los xij, nws yog nkig ntau dua thiab tsis yooj yim dua, ua rau nws nyuaj rau kev tsim cov qauv tsim. Hauv cov ntawv thov uas xav tau kev hloov pauv, xws li cov khoom cua sov me me hauv cov khoom siv hluav taws xob, kanthal feem ntau poob qis, qhov nichrome's ductility tso cai rau kev sib sau ua ke yam tsis muaj kev tawg.
Copper-nickel (Cu-Ni) hlau yog lwm qhov sib tw, muaj nuj nqis rau nws cov kev tiv thaiv corrosion thiab nruab nrab tiv taus. Tab sis Cu-Ni tawm tsam ntawm qhov kub thiab txias, oxidizing sai dua 300 ° C, uas txwv tsis pub siv rau hauv cov xwm txheej kub kub xws li cov cub tawg lossis cua sov coils. Nichrome, los ntawm qhov sib txawv, tswj kev ruaj ntseg txawm tias nyob ntawm 1,200 ° C, ua rau nws muaj ntau yam zoo rau kev ua haujlwm kub.
Tungsten hlau muaj qhov tshwj xeeb kub ua haujlwm, tiv taus huab cua kub txog 3,422 ° C. Txawm li cas los xij, nws tsis tshua muaj nkig thiab muaj hluav taws xob tsis zoo, yuav tsum muaj cov dej ntws ntau dua los ua kom muaj cua sov. Qhov no ua rau nws ua tsis tau zoo rau feem ntau cov ntawv siv cua sov qhov twg lub zog ua haujlwm thiab yooj yim ntawm kev siv teeb meem - thaj chaw uas nichrome, nrog nws qhov zoo tshaj plaws tiv thaiv thiab ua haujlwm, ci.
Stainless hlau xaim feem ntau suav hais tias yog nws tus nqi pheej yig thiab kev tiv thaiv corrosion. Txawm li cas los xij, nws muaj kev tiv thaiv qis dua li nichrome, txhais tau tias nws ua kom muaj cua sov tsawg dua rau ib chav tsev ntev, yuav tsum muaj cov ntsuas tuab lossis siab dua voltages kom phim nichrome cov zis. Sij hawm dhau los, cov hlau tsis muaj steel kuj zoo li deform nyob rau hauv lub sij hawm ntev tshav kub, txo nws cov lifespan piv rau nichrome lub sij hawm ntev stability.
Peb cov khoom siv nichrome hlau hais txog cov kev txwv ntawm kev hloov pauv. Muaj nyob rau hauv ntau qib (xws liNiCr 80/20), lawv muaj kev tiv thaiv zoo rau cov khoom siv hluav taws xob zoo ib yam, zoo heev ductility rau kev yooj yim fabrication, thiab superior oxidation tsis kam ntawm qhov kub thiab txias. Txawm hais tias rau cov khoom siv cua sov hauv cov khoom siv, cov khoom siv hauv chav kuaj, lossis cov khoom siv ua kom sov, peb cov nichrome xaim muab cov kev ua tau zoo, kev siv hluav taws xob, thiab kev ua haujlwm ntev uas lwm txoj kev tawm tsam kom rov ua dua.
Kev xaiv cov hlau zoo txhais tau tias yog qhov tseem ceeb ntawm cov khoom sib xyaw tshwj xeeb uas tsuas yog nichrome muab. Peb cov khoom raug tsim los ua kom tau raws li cov qauv zoo, kom ntseeg tau tias lawv ua tau zoo dua cov kev hloov pauv hauv ob qho tib si ua haujlwm thiab siv tau ntev-ua rau lawv xaiv qhov ntse rau koj cov kev xav tau cua sov.
