Sirta "dahab madow" ee ka dambeysa warshadaha semiconductor photovoltaic: rabitaanka iyo ku tiirsanaanta garaafka isostatic

Garaafyada Isostatic waa walxo aad muhiim u ah sawiradavoltaics iyo semiconductors. Iyada oo kor u kaca degdega ah ee shirkadaha graphite ee gudaha, keli-taliska shirkadaha shisheeye ee Shiinaha waa la jabiyay. Cilmi-baaris madax-bannaan oo joogto ah iyo horumarin iyo horumar tignoolajiyadeed, tilmaamayaasha waxqabadka ee qaar ka mid ah alaabadayada asaasiga ah waxay la siman yihiin ama xitaa ka fiican yihiin kuwa tartamayaasha caalamiga ah. Si kastaba ha ahaatee, saamaynta laba-geesoodka ah ee hoos u dhaca qiimaha alaabta ceeriin iyo dhimista kharashka ee macaamiisha dhamaadka isticmaala, qiimuhu waa uu sii socday hoos u dhaca. Waqtigan xaadirka ah, faa'iidada alaabooyinka hoose ee gudaha ayaa ka yar 20%. Iyada oo si joogto ah loo sii daayo awoodda wax soo saarka, cadaadiska cusub iyo caqabadaha ayaa si tartiib tartiib ah loo keenaa shirkadaha garaafyada isostatic.

1. Waa maxay garaafka isostatic?
Garaafyada istatic-ka ah waxaa loola jeedaa agabka garaafyada ee ay soo saarto cadaadis istatic ah. Sababtoo ah garaafyada isostatically la cadaadiyo waxaa lagu cadaadiyaa si isku mid ah oo joogto ah cadaadiska dareeraha inta lagu jiro habka qaabeynta, walxaha garaafka ee la soo saaro ayaa leh sifooyin aad u fiican. Tan iyo markii ay dhalatay 1960-meeyadii, graphite isostatic waxa uu noqday hogaamiye ka mid ah qalabka garaafka cusub sababtoo ah sifooyinka gaarka ah iyo codsiyada ballaaran.

2. Habka wax-soo-saarka garaafyada ee isostatic
Socodka habka wax soo saarka ee garaafyada isostatically cadaadisay ayaa lagu muujiyay shaxanka. Garaafyada istatic waxay u baahan yihiin agab cayriin oo isotropic ah. Alaabta ceeriin waxay u baahan tahay in lagu shubo budo ka sii fiican. Tiknoolajiyada wax-soo-saarka ee istatic press ayaa loo baahan yahay in la adeegsado. Wareegga dubay aad buu u dheer yahay. Si loo gaaro cufnaanta bartilmaameedka, impregnation badan iyo wareegyo duban ayaa loo baahan yahay. , muddada garaafyada ayaa sidoo kale aad uga dheer garaafyada caadiga ah.

3. Codsiga garaafka isostatic

Garaafyada Isostatic waxay leedahay codsiyo kala duwan oo kala duwan, badi ahaan semiconductor-ka iyo goobaha sawir-qaadista.

In berrinkii photovoltaics, graphite isostatically cadaadisay waxaa inta badan loo isticmaalaa in qaybaha graphite ee garoonka kulaylka graphite ee foornooyinka koritaanka Silicon hal crystal iyo in garoonka kulaylka graphite ee polycrystalline silicon ingot foornada. Gaar ahaan, xirmooyinka wax soo saarka silikoon polycrystalline, qaybiyeyaasha gaaska foornooyinka hydrogenation, walxaha kuleyliyaha, dhululubada dahaarka iyo kuleyliyaha polycrystalline ingot, blocks jihada, iyo sidoo kale tubooyinka hagaha koritaanka crystal hal iyo cabbiro kale oo yar. qaybo;

Dhinaca semiconductors, kuleyliyeyaasha iyo dhululubada dahaarka ee korriinka sapphire hal crystal waxay isticmaali karaan garaafyada isostatic ama garaafka qaabaysan. Intaa waxaa dheer, qaybaha kale sida crucibles, kuleyliyaha, electrodes, taarikada gaashaanka kulaylka, iyo kiristaalo abuurka Qiyaastii 30 nooc oo haystayaal, saldhigyada for crucibles wareeg ah, taarikada wareegyada kala duwan, iyo taarikada milicsiga kulaylka ayaa laga sameeyay graphite isostatically cadaadisay.
