Cov khoom siv hluav taws xob siv nyob rau hauv nruab nrab zaus qhov chaw vuam tshuab?

Kev xaiv ntawm cov khoom siv electrode yog qhov tseem ceeb hauv kev ua haujlwm thiab kev ua haujlwm ntawm qhov nruab nrab zaus qhov chaw vuam tshuab. Kab lus no delves rau hauv ntau yam ntaub ntawv uas feem ntau siv rau electrodes hauv cov tshuab no thiab tham txog lawv cov yam ntxwv thiab qhov zoo.

Txheej txheem cej luam ntawm Electrode Materials: Cov electrodes nyob rau hauv nruab nrab zaus qhov chaw vuam tshuab yog raug rau huab cua kub thiab txhua yam kev nyuaj siab thaum lub sij hawm vuam txheej txheem. Yog li ntawd, cov khoom siv hluav taws xob yuav tsum muaj cov khoom tshwj xeeb kom ntseeg tau tias lub neej ntev, kev hloov hluav taws xob zoo, thiab cov txiaj ntsig zoo welding.

Common Electrode Khoom:

1. Copper Alloys:Copper-based electrode cov ntaub ntawv, xws li chromium zirconium tooj liab (CuCrZr) thiab beryllium tooj liab (CuBe), yog dav siv nyob rau hauv nruab nrab zaus qhov chaw vuam tshuab. Cov alloys no muaj cov thermal conductivity zoo, siab zog, thiab zoo hnav tsis kam. Chromium zirconium tooj liab, tshwj xeeb, yog nyiam rau nws cov cua sov zoo tshaj plaws thiab lub neej ntev electrode.
2. Molybdenum:Molybdenum electrodes paub txog lawv qhov siab melting point, uas ua rau lawv haum rau cov ntawv thov uas muaj qhov kub siab dua. Lawv pom zoo thermal thiab hluav taws xob conductivity, ua rau lawv ua tau zoo rau qee yam haujlwm vuam.
3. Tungsten:Tungsten electrodes yog txaus siab rau lawv cov durability thiab siab melting point. Txawm li cas los xij, lawv muaj cov thermal conductivity qis dua piv rau tooj liab-raws li alloys, uas yuav txwv tsis pub lawv siv hauv qee yam kev siv.
4. Copper Tungsten Alloys:Cov alloys ua ke qhov zoo ntawm ob qho tib si tooj liab thiab tungsten. Lawv muab kev txhim kho kev hnav tsis kam thiab kev ua haujlwm siab kub piv rau cov tooj liab ntshiab thaum tuav cov hluav taws xob zoo.
5. Nyiaj Alloys:Silver-based electrodes paub txog lawv cov hluav taws xob zoo heev thiab thermal zog. Txawm li cas los xij, lawv feem ntau kim dua thiab yuav xav tau kev xaiv zoo rau cov ntawv thov tshwj xeeb.

Qhov zoo ntawm kev xaiv cov khoom siv electrode:

1. Kev Siv Hluav Taws Xob Hluav Taws Xob:Cov khoom siv hluav taws xob tsim nyog ua kom muaj kev hloov pauv hluav taws xob zoo thaum lub sijhawm vuam, uas ua rau muaj qhov zoo sib xws thiab tiv thaiv kev kub dhau.
2. Ntev:Cov khoom siv hluav taws xob uas muaj kev hnav tsis kam thiab kub tsis kam, xws li CuCrZr, ua rau lub neej ntev dua ntawm electrode, txo qis sijhawm thiab nqi kho.
3. Stable Electrical conductivity:Kev xaiv ntawm cov khoom siv electrode cuam tshuam rau kev ruaj ntseg ntawm cov hluav taws xob conductivity, uas yog qhov tseem ceeb rau kev tswj xyuas cov vuam tsis zoo.
4. Txo Weld Defects:Xaiv cov khoom siv hluav taws xob zoo yuav txo tau qhov ua tau zoo ntawm cov nplaum, tawg, thiab lwm yam weld tsis xws luag, ua rau cov welds zoo dua.

Kev xaiv cov khoom siv electrode hauv nruab nrab zaus qhov chaw vuam tshuab yog qhov kev txiav txim siab tseem ceeb uas cuam tshuam rau kev ua haujlwm vuam, electrode lub neej, thiab kev ua haujlwm tag nrho. Copper alloys xws li CuCrZr thiab CuBe yog cov kev xaiv nrov vim lawv cov thermal conductivity zoo heev, hnav tsis kam, thiab kub tsis kam. Ua tib zoo xav txog cov khoom siv hluav taws xob hauv kev sib raug zoo rau kev siv vuam tshwj xeeb yuav pab cov tuam txhab ua tiav cov txiaj ntsig zoo vuam thiab ua kom lub neej ntev ntawm lawv cov khoom siv.
