Chinsinsi cha "golide wakuda" chomwe chili kumbuyo kwa makampani opanga ma semiconductor a photovoltaic: chikhumbo ndi kudalira graphite ya isostatic

Graphite ya isostatic ndi chinthu chofunikira kwambiri mu photovoltaics ndi semiconductors. Chifukwa cha kukwera mwachangu kwa makampani a isostatic graphite akunyumba, mphamvu ya makampani akunja ku China yasweka. Chifukwa cha kafukufuku wodziyimira pawokha komanso chitukuko chopitilira komanso kupita patsogolo kwaukadaulo, zizindikiro za magwiridwe antchito azinthu zina zazikulu zathu zikugwirizana kapena kuposa za omwe akupikisana nawo padziko lonse lapansi. Komabe, chifukwa cha kutsika kwa mitengo yazinthu zopangira komanso kuchepetsa mtengo kwa makasitomala ogwiritsa ntchito, mitengo yapitilira kutsika. Pakadali pano, phindu la zinthu zotsika mtengo zakunyumba ndi lochepera 20%. Chifukwa cha kutulutsidwa kosalekeza kwa mphamvu zopangira, zovuta zatsopano ndi zovuta zimabweretsedwa pang'onopang'ono kumakampani a isostatic graphite.

1. Kodi graphite ya isostatic n’chiyani?

Graphite ya isostatic imatanthauza zinthu za graphite zopangidwa ndi kukanikiza kwa isostatic. Popeza graphite yokanizidwa ndi isostatic imapanikizika mofanana komanso mosalekeza ndi kupanikizika kwamadzimadzi panthawi yopangira, zinthu za graphite zomwe zimapangidwa zimakhala ndi makhalidwe abwino kwambiri. Kuyambira pomwe idabadwa m'ma 1960, graphite ya isostatic yakhala mtsogoleri pakati pa zinthu zatsopano za graphite chifukwa cha makhalidwe ake apadera komanso ntchito zake zosiyanasiyana.

2. Njira yopangira graphite ya Isostatic

Njira yopangira graphite yoponderezedwa ndi isostatic ikuwonetsedwa pachithunzichi. Graphite yoponderezedwa ndi isostatic imafuna zinthu zopangira isotropic. Zinthu zopangira ziyenera kuphwanyidwa kukhala ufa wosalala. Ukadaulo wopondereza wa isostatic uyenera kugwiritsidwa ntchito. Nthawi yophika ndi yayitali kwambiri. Kuti tikwaniritse kuchuluka kwa zinthu zomwe tikufuna, nthawi zambiri zopaka ndi kuwotcha zimafunika. , nthawi yopangira graphite ndi yayitali kwambiri kuposa ya graphite wamba.

3. Kugwiritsa ntchito graphite ya isostatic

Graphite ya isostatic imagwiritsidwa ntchito kwambiri, makamaka m'magawo a semiconductor ndi photovoltaic.

Mu gawo la photovoltaics, graphite yosindikizidwa ndi isostatically imagwiritsidwa ntchito makamaka mu zigawo za graphite mu gawo la kutentha la graphite mu uvuni wa single crystal silicon growth ndi mu gawo la graphite thermal mu uvuni wa polycrystalline silicon ingot. Makamaka, ma clamps opangira zinthu za polycrystalline silicon, ogawa gasi a hydrogenation furnaces, zinthu zotenthetsera, ma insulation cylinders ndi ma polycrystalline ingot heaters, ma directional blocks, komanso ma guide tubes a single crystal growth ndi zina zazing'ono.

Mu gawo la ma semiconductors, ma heater ndi ma insulation cylinders a safiro single crystal growth angagwiritse ntchito isostatic graphite kapena molded graphite. Kuphatikiza apo, zigawo zina monga ma crucibles, ma heaters, ma electrodes, ma heat-insulating shielding plates, ndi ma crystals a mbewu. Mitundu pafupifupi 30 ya ma holders, ma base for rotating crucibles, ma circular plates, ndi ma heat reflection plates amapangidwa ndi graphite yosindikizidwa ndi isostatically.
