Qhov zais cia "kub dub" tom qab kev lag luam photovoltaic semiconductor: kev xav thiab kev vam khom rau isostatic graphite

Isostatic graphite yog ib yam khoom tseem ceeb heev hauv photovoltaics thiab semiconductors. Nrog rau kev nce sai ntawm cov tuam txhab graphite hauv tebchaws, kev tswj hwm ntawm cov tuam txhab txawv teb chaws hauv Suav teb tau raug rhuav tshem. Nrog rau kev tshawb fawb thiab kev txhim kho ywj pheej thiab kev tshawb fawb txog thev naus laus zis, cov ntsuas kev ua tau zoo ntawm qee cov khoom tseem ceeb ntawm peb yog sib npaug lossis zoo dua li cov neeg sib tw thoob ntiaj teb. Txawm li cas los xij, vim muaj ob qho kev cuam tshuam ntawm cov nqi khoom siv raw poob qis thiab kev txo nqi los ntawm cov neeg siv khoom kawg, cov nqi tau txuas ntxiv poob qis. Tam sim no, cov txiaj ntsig ntawm cov khoom lag luam qis hauv tebchaws tsawg dua 20%. Nrog rau kev tso tawm tas mus li ntawm lub peev xwm tsim khoom, cov kev nyuaj siab tshiab thiab cov teeb meem tau maj mam coj los rau cov tuam txhab graphite isostatic.

1. Dab tsi yog isostatic graphite?

Isostatic graphite yog hais txog cov khoom siv graphite uas tsim los ntawm kev nias isostatic. Vim tias graphite uas nias isostatically raug nias kom sib npaug thiab ruaj khov los ntawm kev nias kua thaum lub sijhawm molding, cov khoom siv graphite uas tsim tawm muaj cov yam ntxwv zoo heev. Txij li thaum nws yug los rau xyoo 1960, isostatic graphite tau dhau los ua tus thawj coj ntawm cov khoom siv graphite tshiab vim nws cov yam ntxwv tshwj xeeb thiab ntau yam kev siv.

2. Cov txheej txheem tsim cov graphite isostatic

Cov txheej txheem ntau lawm ntawm isostatically pressed graphite tau qhia hauv daim duab. Isostatic graphite xav tau cov khoom siv raw isotropic. Cov khoom siv raw yuav tsum tau zom ua hmoov zoo dua. Yuav tsum tau siv cov thev naus laus zis isostatic pressing molding. Lub voj voog ci ntev heev. Yuav kom ua tiav qhov ceev ntawm lub hom phiaj, yuav tsum muaj ntau lub voj voog impregnation thiab roasting. , lub sijhawm graphitization kuj ntev dua li ntawm graphite ib txwm muaj.

3. Daim ntawv thov ntawm isostatic graphite

Isostatic graphite muaj ntau yam kev siv, feem ntau yog nyob rau hauv semiconductor thiab photovoltaic teb.

Hauv thaj chaw ntawm photovoltaics, isostatically pressed graphite feem ntau yog siv rau hauv cov khoom graphite hauv graphite thermal teb hauv ib qho crystal silicon loj hlob furnaces thiab hauv graphite thermal teb hauv polycrystalline silicon ingot furnaces. Tshwj xeeb, clamps rau polycrystalline silicon khoom tsim, roj faib rau hydrogenation furnaces, cua sov ntsiab lus, rwb thaiv tsev lub tog raj kheej thiab polycrystalline ingot cua sov, directional blocks, nrog rau cov yeeb nkab qhia rau ib qho crystal loj hlob thiab lwm yam me me. qhov chaw;

Hauv thaj chaw ntawm semiconductors, cua sov thiab cov thooj voos kheej kheej rwb thaiv tsev rau sapphire ib leeg siv lead ua kev loj hlob tuaj yeem siv isostatic graphite lossis molded graphite. Tsis tas li ntawd, lwm yam khoom xws li crucibles, cua sov, electrodes, cua sov-insulating shielding plates, thiab noob siv lead ua Kwv yees li 30 hom tuav, lub hauv paus rau rotating crucibles, ntau yam voj voog phaj, thiab cua sov reflection phaj yog ua los ntawm isostatically nias graphite.
