Iyo "goridhe dema" chakavanzika kuseri kweiyo photovoltaic semiconductor indasitiri: chishuwo uye kutsamira pane isostatic graphite.

Isostatic graphite chinhu chakakosha zvikuru mu photovoltaics uye semiconductors. Nekukurumidza kusimuka kwemakambani emudzimba isostatic graphite, hutongi hwemakambani ekunze muChina hwatyorwa. Nekuenderera mberi kwakazvimirira kwekutsvaga nekusimudzira uye kubudirira kwetekinoroji, zviratidzo zvekushanda zvezvimwe zvezvigadzirwa zvedu zvakakosha zviri padanho kana kuti zvirinani pane izvo zvevakwikwidzi vepasi rese. Nekudaro, nekuda kwekukanganisa kuviri kwekudonha kwemitengo yezvinhu uye kudzikiswa kwemitengo nevatengi vekupedzisira-mushandisi, mitengo yakaramba ichidzika. Parizvino, purofiti yezvigadzirwa zvepamusha zvakaderera zviri pasi pe20%. Nekuenderera kuburitswa kwesimba rekugadzira, kudzvanyirira kutsva nematambudziko zvinounzwa zvishoma nezvishoma kumakambani eisostatic graphite.

1. Chii chinonzi isostatic graphite?

Isostatic graphite inoreva graphite zvinhu zvinogadzirwa ne isostatic kudzvanya. Nekuti isostatically yakadzvanywa graphite inodzvanywa zvakafanana uye zvishoma nezvishoma nekumanikidzwa kwemvura panguva yekuumbwa, iyo graphite zvinhu inogadzirwa ine yakanakisa zvimiro. Kubva payakazvarwa muma1960, isostatic graphite yave mutungamiri pakati pezvinhu zvitsva zvegraphite nekuda kweiyo yakasarudzika zvivakwa uye kuwanda kwekushandisa.

2. Isostatic graphite kugadzira maitiro

Iyo yekugadzira inoyerera yeisostatically yakadzvanywa graphite inoratidzwa mumufananidzo. Isostatic graphite inoda structural isotropic mbishi zvinhu. Iyo mbishi inoda kukuyiwa kuita hupfu hwakatsetseka. Isostatic pressing molding tekinoroji inoda kuiswa. Kugocha kurefu kwazvo. Kuti uwane iyo yakanangwa density, akawanda impregnation uye kugocha matenderedzwa anodiwa. , nguva ye graphitization zvakare yakareba kudarika iyo yegirafu yakajairwa.

3. Kushandisa isostatic graphite

Isostatic graphite ine huwandu hwakawanda hwekushandisa, kunyanya mu semiconductor uye photovoltaic minda.

Mumunda we photovoltaics, isostatically yakadzvanywa graphite inonyanya kushandiswa mu graphite zvikamu mu graphite thermal field mune imwe chete crystal silicon kukura furnaces uye mu graphite thermal field mu polycrystalline silicon ingot furnaces. Kunyanya, zvibatiso zvepolycrystalline silicon kugadzirwa kwezvinhu, gasi vanogovanisa hydrogenation mavira, zvinhu zvekudziya, masilinda ekudzivirira uye polycrystalline ingot heaters, anotungamira mabhuroki, pamwe nemachubhu ekutungamira ekukura kwekristaro imwe chete uye mamwe madiki madiki. zvikamu;

Mumunda we semiconductors, heaters uye insulation cylinders yesafire single crystal kukura inogona kushandisa kana isostatic graphite kana molded graphite. Mukuwedzera, zvimwe zvikamu zvakadai sema crucibles, heaters, electrodes, heat-insulating shielding plates, uye makristasi embeu Anenge makumi matatu emhando dzezvibatiso, zvigadziko zvekutenderera crucibles, mahwendefa akasiyana-siyana anotenderera, uye mahwendefa ekuratidzira kupisa anogadzirwa neisostatically pressed graphite.
