High tsarki graphite taushi ji
Ƙarin Bayanan:
1. Wasu sunaye: m graphite rufi ji, semiconductor thermal filin taushi ji, graphite ji.
2. Aikace-aikace: Thermal filin rufi na semiconductor, photovoltaic kayan aiki, injin high matsa lamba gas quenching makera, monoclistallin silicon makera da sauran high zafin jiki kayan aiki rufi.
3. Core sigogi: tsarki ≥99.99%, matsakaicin haƙuri zafin jiki 3000 ℃, thermal watsin 0.15-0.24W / m · K.
description
Semixlab shine babban masana'anta na babban ginshiƙi mai laushi mai laushi a cikin Sin, yana mai da hankali kan samar da manyan hanyoyin samar da wutar lantarki don masana'antar semiconductor, photovoltaic da filayen masana'antu masu zafin jiki. Wannan samfurin rungumi dabi'ar shigo da high-tsarki graphite albarkatun kasa (najasa abun ciki ≤0.1%), Ya sanya daga fiber cibiyar sadarwa tsarin ta musamman tsari, kuma yana da core halaye irin su matsananci-low thermal watsin (≤ 0.25W / m · K a 1000 ℃), matsananci high zafin jiki juriya (ci gaba da amfani da zafin jiki na 3000 ℃) a cikin sinadaran gina jiki. madaidaicin tsarin filin thermal.
High-tsarki graphite taushi ji shi ne ainihin rufi abu don thermal filin tsarin semiconductor da photovoltaic kayan aiki. Ta hanyar madaidaicin saƙa da tara manyan zaruruwan graphite masu tsafta, an samar da wani tsari mara ƙarfi tare da ƙarancin ƙarfin zafi. A cikin yanayin zafi mai girma (misali, sama da 800 ℃), yana rage asarar zafi sosai ta hanyar nuna zafi mai haske da rage hanyar canja wurin zafi mai ƙarfi.
Dangane da bambancin albarkatun kasa, samfuran sun kasu kashi uku:
PAN-tushen graphite taushi ji: m inji Properties, sauki samar tsari, yadu amfani da tsarin goyon bayan kayan.
Viscose-tushen graphite taushi ji: karfi ablative juriya, high fasaha wahala, dace da high zafin jiki rufi wuri.
Pitch tushen graphite taushi ji: mai arziki a cikin albarkatun kasa, high carbonization yawan amfanin ƙasa, amma kasuwa aikace-aikace kunkuntar.
