Kev lag luam semiconductor yog ib qho kev lag luam tawm tshiab thiab thev naus laus zis, uas tau nyiam cov xim zoo nkauj nyob rau xyoo tas los no, ntau thiab ntau lub tuam txhab tau pib nkag mus rau hauv kev lag luam semiconductor, thiab graphite tau dhau los ua ib qho ntawm cov ntaub ntawv tseem ceeb rau kev txhim kho kev lag luam semiconductor. Semiconductors yuav tsum tau siv cov hluav taws xob conductivity ntawm graphite, vim hais tias ntau dua cov pa roj carbon ntsiab lus ntawm graphite, qhov zoo dua cov hluav taws xob conductivity, feem ntau yuav tsum tau xav txog cov ntsuas yog: particle loj, tshav kub tsis kam, purity.
Cov qoob loo loj sib xws rau cov lej sib txawv, thiab cov lus qhia tshwj xeeb tau qhia hauv cov lej mesh. Tus lej mesh yog tus naj npawb ntawm qhov, uas yog, tus naj npawb ntawm qhov ib square inch. Feem ntau hais lus, mesh tooj * aperture (micron) = 15000. Qhov loj mesh tooj ntawm conductive graphite, qhov me me particle loj, qhov zoo dua lub lubrication kev ua tau zoo, yuav siv tau nyob rau hauv lub teb ntawm lubricating cov ntaub ntawv ntau lawm. Qhov loj me me siv hauv kev lag luam semiconductor yuav tsum zoo heev, vim tias nws yooj yim dua rau kev ua tiav precision, siab compressive zog, thiab poob me me, tshwj xeeb tshaj yog rau sintering pwm, xav tau kev ua haujlwm siab.
Particle loj faib, xws li: 20 mesh, 40 mesh, 80 mesh, 100 mesh, 200 mesh, 320 mesh, 500 mesh, 800 mesh, 1200 mesh, 2000 mesh, 3000 mesh, 5000 mesh, 8000 mesh zoo tshaj plaws yuav ua tau 15,000 mesh.
Ntau cov khoom lag luam hauv kev lag luam semiconductor yuav tsum tau ua kom sov tsis tu ncua, txhawm rau txhawm rau txuas lub neej kev pab cuam ntawm lub cuab yeej, uas yuav tsum muaj cov khoom siv hluav taws xob kom muaj cov khoom nram qab no: kev ntseeg tau zoo heev thiab kub kub cuam tshuam.
Cov kev xav tau ntawm graphite ntau lawm hauv kev lag luam semiconductor yog: qhov siab dua qhov purity, qhov zoo dua, tshwj xeeb tshaj yog cov khoom siv graphite uas kov ntawm ob, yog tias lawv muaj ntau dhau impurities, lawv yuav ua paug rau cov khoom siv semiconductor. Yog li ntawd, peb yuav tsum nruj me ntsis tswj cov purity ntawm conductive graphite, thiab peb kuj yuav tsum tau kho lawv nrog kub kub graphitization thiaj li yuav txo tau cov grey theem.
