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

I-graphite ye-Isostatic iyinto ebaluleke kakhulu kuma-photovoltaics nama-semiconductors. Ngokukhula okusheshayo kwezinkampani zasekhaya ze-isostatic graphite, ukubusa kwezinkampani zakwamanye amazwe eChina kwephukile. Ngocwaningo oluqhubekayo oluzimele kanye nentuthuko kanye nempumelelo yezobuchwepheshe, izinkomba zokusebenza zeminye yemikhiqizo yethu eyinhloko zilingana noma zingcono nakakhulu kunezo zamazwe ngamazwe esiqhudelana nazo. Kodwa-ke, ngenxa yomthelela okabili wokuwa kwentengo yezinto ezingavuthiwe kanye nokwehliswa kwezindleko ngamakhasimende angabasebenzisi bokugcina, amanani aqhubekile nokwehla. Njengamanje, inzuzo yemikhiqizo yasekhaya esezingeni eliphansi ingaphansi kwama-20%. Ngokukhululwa okuqhubekayo komthamo wokukhiqiza, izingcindezi ezintsha nezinselele kancane kancane zilethwa ezinkampanini ze-isostatic graphite.

1. Iyini i-isostatic graphite?

I-Isostatic graphite ibhekisela ezintweni ze-graphite ezikhiqizwa ukucindezela kwe-isostatic. Ngenxa yokuthi i-graphite ecindezelwe nge-isostatically icindezelwa ngokufanayo futhi kancane kancane ukucindezela koketshezi ngesikhathi sokubumba, izinto ze-graphite ezikhiqizwayo zinezici ezinhle kakhulu. Kusukela yazalwa ngawo-1960, i-isostatic graphite isibe umholi phakathi kwezinto ezintsha ze-graphite ngenxa yezakhiwo zayo eziyingqayizivele kanye nohlu olubanzi lwezinhlelo zokusebenza.

2. Inqubo yokukhiqiza i-graphite ye-Isostatic

Ukugeleza kwenqubo yokukhiqiza ye-graphite ecindezelwe ngokwe-isostatically kubonisiwe esithombeni. I-Isostatic graphite idinga izinto zokusetshenziswa ze-isotropic ngokwesakhiwo. Izinto ezingavuthiwe zidinga ukugaywa zibe izimpushana ezicolekile. Ubuchwepheshe bokubumba obucindezela be-Isostatic budinga ukusetshenziswa. Umjikelezo wokugazinga mude kakhulu. Ukuze kuzuzwe ukuminyana okuhlosiwe, ukumilisa okuningi kanye nemijikelezo yokugazinga kuyadingeka. , isikhathi se-graphitization futhi side kakhulu kuneso se-graphite evamile.

3. Ukusetshenziswa kwe-isostatic graphite

I-graphite ye-Isostatic inohlu olubanzi lwezinhlelo zokusebenza, ikakhulukazi emkhakheni we-semiconductor kanye ne-photovoltaic.

Emkhakheni we-photovoltaics, i-graphite ecindezelwe nge-isostatically isetshenziswa ikakhulukazi ezingxenyeni zegraphite emkhakheni oshisayo wegraphite ezithandweni zokukhulisa i-silicon eyodwa yekristalu kanye nasensimini eshisayo ye-graphite ku-polycrystalline silicon ingot furnaces. Ngokukhethekile, izinsimbi zokukhiqiza izinto ezibonakalayo ze-polycrystalline silicon, abasabalalisi begesi bamaziko e-hydrogenation, izakhi zokushisa, amasilinda okufakwa ngaphakathi kanye nama-heaters e-ingot e-polycrystalline, amabhlogo aqondisayo, kanye namashubhu okuqondisa ukukhula kwekristalu eyodwa nosayizi abancane. izingxenye;

Emkhakheni wama-semiconductors, ama-heaters nama-insulation cylinders for sapphire single crystal ukukhula angasebenzisa i-isostatic graphite noma i-graphite ebunjiwe. Ngaphezu kwalokho, ezinye izakhi ezifana nezikhilimu, izifudumezi, ama-electrode, amapuleti okuvikela ukushisa, namakristalu embewu Mayelana nezinhlobo ezingu-30 zabanikazi, izisekelo ze-crucibles ezijikelezayo, amapuleti ahlukahlukene ayindilinga, namapuleti okubonisa ukushisa ayenziwe nge-graphite ecindezelwe isostatically.
