Imfihlo "yegolide elimnyama" ngemuva kwemboni ye-semiconductor ye-photovoltaic: isifiso kanye nokuncika ku-graphite e-isostatic

I-graphite e-isostatic iyinto ebaluleke kakhulu kuma-photovoltaics nama-semiconductor. Ngokukhula okusheshayo kwezinkampani ze-graphite ezi-isostatic zasekhaya, ukuzimela kwezinkampani zakwamanye amazwe eShayina kuye kwaphulwa. Ngocwaningo oluzimele oluqhubekayo kanye nentuthuko kanye nokuthuthuka kwezobuchwepheshe, izinkomba zokusebenza kweminye yemikhiqizo yethu eyinhloko ziyafana noma zingcono kunezo zabancintisani bamazwe ngamazwe. Kodwa-ke, ngenxa yomthelela ophindwe kabili wokwehla kwamanani ezinto zokusetshenziswa kanye nokwehliswa kwezindleko ngamakhasimende abasebenzisi bokugcina, amanani aqhubekile nokwehla. Njengamanje, inzuzo yemikhiqizo yasekhaya esezingeni eliphansi ingaphansi kuka-20%. Ngokukhululwa okuqhubekayo kwamandla okukhiqiza, izingcindezi ezintsha kanye nezinselele kulethwa kancane kancane ezinkampanini ze-graphite ezi-isostatic.

1. Kuyini i-graphite e-isostatic?

I-graphite e-isostatic ibhekisela ezintweni ze-graphite ezikhiqizwa ngokucindezela kwe-isostatic. Ngenxa yokuthi i-graphite ecindezelwe nge-isostatic icindezelwa ngokulinganayo nangokuqhubekayo ngokucindezela koketshezi ngesikhathi senqubo yokubumba, izinto ze-graphite ezikhiqizwayo zinezakhiwo ezinhle kakhulu. Kusukela yazalwa ngawo-1960, i-graphite e-isostatic ibe ngumholi phakathi kwezinto ezintsha ze-graphite ngenxa yezakhiwo zayo ezihlukile kanye nohlu olubanzi lwezicelo.

2. Inqubo yokukhiqiza i-graphite engashintshi

Ukugeleza kwenqubo yokukhiqiza kwe-graphite ecindezelwe nge-isostatically kuboniswe esithombeni. I-graphite ye-isostatic idinga izinto zokusetshenziswa ezi-isotropic ngokwesakhiwo. Izinto zokusetshenziswa zidinga ukugaywa zibe yizimpuphu ezincane. Ubuchwepheshe bokubumba bokucindezela nge-isostatic budinga ukusetshenziswa. Umjikelezo wokosa mude kakhulu. Ukuze kufezwe ubuningi obuqondiwe, kudingeka imijikelezo eminingi yokufakwa kanye nokosa. , isikhathi se-graphitization naso side kakhulu kunese-graphite evamile.

3. Ukusetshenziswa kwe-graphite e-isostatic

I-graphite ye-isostatic inezinhlobo eziningi zezicelo, ikakhulukazi emasimini e-semiconductor kanye ne-photovoltaic.

Emkhakheni we-photovoltaics, i-graphite ecindezelwe nge-isostatically isetshenziswa kakhulu ezingxenyeni ze-graphite ensimini yokushisa ye-graphite ezitsheni zokukhula ze-silicon eyodwa kanye nasensimini yokushisa ye-graphite ezitsheni ze-silicon ezine-polycrystalline. Ngokukhethekile, ama-clamp okukhiqizwa kwezinto ze-silicon ezine-polycrystalline, abasabalalisi begesi bezitofu ze-hydrogenation, izinto zokushisa, amasilinda okushisa kanye nama-heater e-ingot ane-polycrystalline, amabhlogo aqondisayo, kanye namashubhu okuqondisa okukhula kwe-crystal eyodwa kanye nezinye izingxenye ezincane;

Emkhakheni wama-semiconductor, ama-heater kanye nama-insulation cylinder okukhulisa i-sapphire single crystal angasebenzisa i-isostatic graphite noma i-molded graphite. Ngaphezu kwalokho, ezinye izingxenye ezifana nama-crucible, ama-heater, ama-electrode, ama-heat-insulating shielding plate, kanye nama-seed crystals Cishe izinhlobo ezingu-30 zezibambi, izisekelo zama-crucible ajikelezayo, ama-plate ahlukahlukene ayindilinga, kanye nama-plate okubonisa ukushisa enziwe nge-graphite ecindezelwe nge-isostatically.
