Chakavanzika che "goridhe dema" chiri shure kweindasitiri ye photovoltaic semiconductor: chishuwo uye kuvimba ne isostatic graphite

Graphite inotenderera ibasa rinokosha zvikuru mumagetsi emagetsi (photovoltaics) uye semiconductors. Nekukura kuri kuita makambani emagetsi emagetsi ekunze muChina, simba remakambani ekunze muChina rakaparara. Nekutsvaga nekuvandudza kwakazvimirira uye kufambira mberi kwetekinoroji, zviratidzo zvekushanda kwezvimwe zvigadzirwa zvedu zvikuru zvakaenzana kana kuti zviri nani kupfuura zvevanokwikwidza pasi rose. Zvisinei, nekuda kwekuderera kwemitengo yezvinhu zvakagadzirwa uye kudzikira kwemitengo nevatengi vanoshandisa magetsi, mitengo yakaramba ichiderera. Pari zvino, purofiti yezvigadzirwa zvemagetsi epasi iri pasi pe20%. Nekuburitswa kwesimba rekugadzira, kumanikidzwa kutsva nematambudziko zvinounzwa zvishoma nezvishoma kumakambani emagetsi emagetsi ekunze.

1. Chii chinonzi isostatic graphite?

Graphite inoshanduka inoreva zvinhu zvegraphite zvinogadzirwa nekudzvanywa kweisostatic. Nekuti graphite inodzvanywa neisostatic inomanikidzwa zvakaenzana uye zvishoma nezvishoma nekumanikidzwa kwemvura panguva yekuumbwa, zvinhu zvegraphite zvinogadzirwa zvine hunhu hwakanaka. Kubva payakazvarwa muma1960, graphite inoshanduka inotungamira pakati pezvinhu zvitsva zvegraphite nekuda kwehunhu hwayo hwakasiyana uye mashandisirwo akasiyana-siyana.

2. Maitiro ekugadzira graphite yeIsostatic

Kufamba kwekugadzira graphite yakadzvanywa ne isostatically kunoratidzwa mumufananidzo. Isostatic graphite inoda zvinhu zvakasvinwa zvine chimiro che isotropic. Zvinhu zvakasvinwa zvinofanirwa kukuyiwa kuita hupfu hwakatsetseka. Tekinoroji yekuumba isostatic pressing inoda kushandiswa. Kurocha kwenguva refu kwazvo. Kuti uwane huwandu hwaunoda, kurocha kakawanda uye kupinza zvinhu zvinodikanwa. , nguva ye graphitization yakarebawo kupfuura ye graphite yakajairika.

3. Kushandiswa kwe isostatic graphite

Graphite yeIsostatic ine mashandisirwo akasiyana-siyana, kunyanya muminda ye semiconductor ne photovoltaic.

Mumunda we photovoltaics, graphite inodzvanywa ne isostatically inonyanya kushandiswa muzvikamu zve graphite mumunda we thermal we graphite muzvitofu zve single crystal silicon growth uye mumunda we graphite thermal muzvitofu zve polycrystalline silicon ingot. Kunyanya, zvisungo zve polycrystalline silicon material, vagovanisi vegasi ve hydrogenation furnaces, heating elements, insulation cylinders uye polycrystalline ingot heaters, directional blocks, pamwe nemachubhu ekutungamira ekukura kwe single crystal nezvimwe zvikamu zvidiki;

Muminda yema semiconductors, ma heater nema insulation cylinders ekugadzira girazi rimwe chete resafire anogona kushandisa isostatic graphite kana molded graphite. Pamusoro pezvo, zvimwe zvikamu zvakaita se crucibles, heaters, electrodes, heat-insulating shielding plates, uye seed crystals. Mhando dzinosvika makumi matatu dzezvibatiso, mabhesi e rotating crucibles, akasiyana-siyana denderedzwa, uye heat reflection plates zvakagadzirwa ne graphite yakadzvanywa ne isostatically.
