Chinsinsi cha "golide wakuda" kumbuyo kwa mafakitale a photovoltaic semiconductor: chikhumbo ndi kudalira graphite ya isostatic

Isostatic graphite ndi chinthu chofunikira kwambiri mu photovoltaics ndi semiconductors. Ndi kukwera kwachangu kwamakampani apakhomo a isostatic graphite, kulamulira kwamakampani akunja ku China kwasweka. Ndi kafukufuku wodziyimira pawokha komanso chitukuko komanso kupita patsogolo kwaukadaulo, zisonyezo za magwiridwe antchito azinthu zathu zazikulu zimafanana kapena zili bwino kuposa za omwe akupikisana nawo mayiko. Komabe, chifukwa cha kukhudzidwa kwapawiri kwa kugwa kwamitengo yamtengo wapatali komanso kuchepetsa mtengo kwa makasitomala ogwiritsira ntchito mapeto, mitengo ikupitirizabe kutsika. Pakalipano, phindu la zinthu zapakhomo zotsika mtengo ndi zosakwana 20%. Ndi kutulutsidwa kosalekeza kwa mphamvu zopanga, zovuta zatsopano ndi zovuta zimabweretsedwa pang'onopang'ono kumakampani a isostatic graphite.

1. Kodi isostatic graphite ndi chiyani?

Isostatic graphite imatanthawuza zida za graphite zopangidwa ndi kukakamiza kwa isostatic. Chifukwa isostatically mbamuikha graphite ndi pressurized uniformly ndi pang'onopang'ono ndi kuthamanga madzi pa akamaumba ndondomeko, zinthu graphite opangidwa ali kwambiri katundu. Kuyambira kubadwa kwake m'ma 1960, isostatic graphite yakhala mtsogoleri pakati pa zida zatsopano za graphite chifukwa cha mawonekedwe ake apadera komanso ntchito zosiyanasiyana.

2. Isostatic graphite kupanga ndondomeko

Njira yopangira ma graphite yoponderezedwa ndi isostatically ikuwonetsedwa pachithunzichi. Isostatic graphite imafuna structural isotropic zipangizo. Zopangirazo ziyenera kuphwanyidwa kukhala ufa wonyezimira. Ukadaulo wakuumba wa Isostatic uyenera kugwiritsidwa ntchito. Nthawi yowotcha ndi yayitali kwambiri. Kuti tikwaniritse kachulukidwe chandamale, kuyimba kambirimbiri ndikuwotcha kumafunika. , nthawi ya graphitization ndi yaitali kwambiri kuposa graphite wamba.

3. Kugwiritsa ntchito isostatic graphite

Isostatic graphite ili ndi ntchito zosiyanasiyana, makamaka m'minda ya semiconductor ndi photovoltaic.

M'munda wa photovoltaics, graphite yoponderezedwa ndi isostatically imagwiritsidwa ntchito kwambiri pazigawo za graphite m'munda wotentha wa graphite m'ng'anjo zokulirapo za crystal silicon komanso m'munda wotentha wa graphite mu ng'anjo za polycrystalline silicon. Makamaka, zotchingira zopangira zinthu za polycrystalline silicon, zogawa gasi za ng'anjo za hydrogenation, zinthu zotenthetsera, masilinda otsekera ndi ma heaters a polycrystalline ingot, midadada yolowera, komanso machubu owongolera kukula kwa kristalo limodzi ndi kukula kwina kocheperako. zigawo;

M'munda wa semiconductors, heaters ndi kutchinjiriza masilindala kwa safiro single krustalo kukula angagwiritse ntchito mwina isostatic graphite kapena kuumbidwa graphite. Kuonjezera apo, zigawo zina monga crucibles, heaters, electrodes, heat-insulating shielding plates, ndi makristasi a mbewu Pafupifupi mitundu 30 ya zosungira, zoyambira zozungulira, mbale zozungulira zosiyanasiyana, ndi mbale zowonetsera kutentha zimapangidwa ndi graphite ya isostatically.
