Qhov zoo ntawm graphite raws li cov khoom siv hluav taws xob

Dab tsi yog qhov zoo ntawm graphite cov ntaub ntawv tshaj tooj liab pwm cov hluav taws xob?

1, ntau dua 90% ntawm cov ntaub ntawv electrode hauv Europe xaiv graphite raws li cov khoom siv electrode. Tooj liab, ib zaug tseem ceeb electrode cov khoom, tau yuav luag los ntawm nws cov zoo piv rau graphite electrodes.

2, vim li cas vim li cas graphite yog siv los ua cov electrode:

1. Kev ua nrawm dua: Feem ntau, kev ua tshuab ua ceev ntawm graphite tuaj yeem yog 2-5 zaug sai dua li tus tooj liab ntau dua li ntawd tooj liab; Thiab cov paug hluav taws xob kom ceev yog 2-3 zaug nrawm dua li tooj liab;
2. Cov khoom siv yog tsawg dua qub rau deformation: nws tau pom tseeb zoo nyob rau hauv kev ua cov lej sib txuas; Qhov muag muag muag ntawm tooj liab yog ib ncig ntawm 1000 degrees, uas yog nquag mus deformation vim muaj cua sov; Lub sublimation kub ntawm graphite yog 3650 degrees; Cov coefficient ntawm thermal expansion tsuas yog 1/30 ntawm tus tooj liab.
3. Qhov hnyav sib dua: qhov ceev ntawm graphite tsuas yog 1/5 ntawm tooj liab, thiab thaum siv electrodes loj rau kev tawm lub nra, nws tuaj yeem txo cov cuab yeej rau ntawm cov cuab yeej siv hluav taws xob (EDM); Tsim nyog rau kev thov rau cov pwm loj.
4. Tsawg dua kev noj haus; Vim tias muaj c c atoms nyob rau hauv cov roj txim roj, thaum lub sij hawm tso tawm, cov yeeb yaj kiab tiv thaiv nyob rau hauv cov duab kab hluav taws xob, them nyiaj rau qhov ploj ntawm graphip electrode.
