Isostatic graphite yog cov khoom tseem ceeb hauv photovoltaics thiab semiconductors. Nrog rau kev nce ceev ntawm cov tuam txhab isostatic graphite, kev lag luam ntawm cov tuam txhab txawv teb chaws hauv Suav teb tau tawg. Nrog rau kev tshawb fawb ywj pheej txuas ntxiv thiab kev txhim kho thiab kev ua haujlwm thev naus laus zis, cov ntsuas kev ua tau zoo ntawm qee yam ntawm peb cov khoom tseem ceeb yog sib npaug nrog lossis zoo dua li cov neeg sib tw thoob ntiaj teb. Txawm li cas los xij, vim muaj kev cuam tshuam ob qho ntawm cov nqi raw khoom poob thiab txo tus nqi los ntawm cov neeg siv khoom kawg, cov nqi tau txuas ntxiv mus. Tam sim no, cov txiaj ntsig ntawm cov khoom lag luam qis kawg hauv tsev yog tsawg dua 20%. Nrog rau kev tso tawm tas li ntawm lub peev xwm ntau lawm, cov kev ntxhov siab tshiab thiab cov kev sib tw tau maj mam coj mus rau isostatic graphite tuam txhab.
1. isostatic graphite yog dab tsi?
Isostatic graphite hais txog graphite cov ntaub ntawv uas tsim los ntawm isostatic nias. Vim tias isostatically pressed graphite yog pressurized uniformly thiab tsis tu ncua los ntawm cov kua siab thaum lub sij hawm molding txheej txheem, cov khoom graphite tsim muaj cov khoom zoo heev. Txij li thaum nws yug los hauv 1960s, isostatic graphite tau dhau los ua tus thawj coj ntawm cov khoom siv graphite tshiab vim nws cov khoom tshwj xeeb thiab ntau yam kev siv.
2. Isostatic graphite txheej txheem ntau lawm
Cov txheej txheem ntau lawm ntws ntawm isostatically nias graphite yog qhia hauv daim duab. Isostatic graphite xav tau cov ntaub ntawv raw isotropic structurally. Cov khoom siv raw yuav tsum tau muab tso rau hauv cov hmoov zoo. Isostatic nias molding tshuab yuav tsum tau siv. Lub voj voog roasting yog ntev heev. Yuav kom ua tiav lub hom phiaj ceev, ntau yam impregnation thiab roasting cycles yuav tsum tau. , lub sij hawm graphitization kuj ntev dua li cov graphite zoo tib yam.
3. Daim ntawv thov ntawm isostatic graphite
Isostatic graphite muaj ntau yam kev siv, feem ntau nyob rau hauv semiconductor thiab photovoltaic teb.
Nyob rau hauv lub tshav pob ntawm photovoltaics, isostatically pressed graphite yog tsuas yog siv nyob rau hauv graphite Cheebtsam nyob rau hauv lub graphite thermal teb nyob rau hauv ib tug siv lead ua silicon loj hlob furnaces thiab nyob rau hauv lub graphite thermal teb nyob rau hauv polycrystalline silicon ingot furnaces. Tshwj xeeb, clamps rau polycrystalline silicon cov khoom siv ntau lawm, roj distributors rau hydrogenation furnaces, cov khoom cua sov, rwb thaiv tsev lub tog raj kheej thiab polycrystalline ingot heaters, directional blocks, raws li zoo raws li qhia cov raj rau ib tug siv lead ua kev loj hlob thiab lwm yam me me. qhov chaw;
Nyob rau hauv lub tshav pob ntawm semiconductors, cua sov thiab rwb thaiv tsev thooj voos kheej kheej rau sapphire ib leeg siv lead ua loj hlob tuaj yeem siv cov isostatic graphite lossis molded graphite. Tsis tas li ntawd, lwm yam khoom xws li crucibles, heaters, electrodes, heat-insulating shielding plates, thiab noob crystals Txog 30 hom tuav, lub hauv paus rau rotating crucibles, ntau lub voj voog daim hlau, thiab cov phaj cua sov yog ua los ntawm isostatically pressed graphite.
