Farqiga aasaasiga ah iyo xaaladaha dalabka ee garaafka iyo kaarboon
2025-03-13
Graphite iyo kaarboon waxay si aad ah ugu kala duwan yihiin qaababka wax soo saarka, guryaha jirka, iyo codsigooda ku qeexan doorarkooda, iyo teknolojiyadda tamarta ee soo ifbaxa.
1.Maxaynta halabuurka iyo hanaan wax soo saar
ElectRites-ka garaafka waxay ka kooban yihiin cirbad coke iyo garoonka, dhuxusha oo ay maraan 12 tillaabo wax soo saar oo sax ah, oo ay ku jiraan garaafyada iyo garashada. Hawshani waxay keenaysaa in lagu nadiifiyo 'ultra-sarre' (> 99% kaarboon kaarboon) iyo iska caabin kuleyl heer sare ah (> 3600 c). Taa bedelkeeda, kaarboon-galeynada waxaa laga soo saaraa codka macdanta iyo ku-meel-gaarka ah hanaanka dubista, oo lagu gaarayo kaarboon-ka-bixiye ah 90% -95% kaliya 1/5 qiimaha.
2. isbarbardhiga hantida
Garaafeedka garaafka ayaa muujinaya adkaynta sare (Xoog dabacsanaanta: 15-25 MPA) iyo dib u dhac koronto oo hooseeya (5-10 μω · m). Isugeyntooda kuleylka (CTE) waa mid hoose oo ah 2-4 × 10⁻⁶ / ° C, hubinta xasilloonida qaab-dhismeedka heerkulka kor u kaca ilaa 1600 ° C. Kaarboon kowaamada, marka la barbardhigo, waa kuwo dabacsan (dhumucyo: 0.1-5 mm), oo leh CTE sare oo ah 8-12 ° 10⁻⁶ / ° C, iyaga oo ka dhigaya mid ku habboon jawiga kuleylka firfircoon.
3. Booska Goobaha Gudaha
Cilmiga korantada ee garaafka ayaa ku dhawaad 95% ka mid ah foornada ARC ee korontada (EAF) Suuqa sahlan, oo ku tabaruca in ka badan 60% wax soo saarka birta adduunka ee adduunka. Afka-dhexroobka culus ee ultra (uhp) garaafka elektroonikada Kaadiyaha kowaamada, dhinaca kale, Excel ee codsiyada korantada, sida aluminium elektrolysis oo leh 95% hufnaanta hadda jirta iyo awoodaha dhabta ah (CDI) oo leh awood quusinimo oo ah 40 mg / g.
4. Indurdundry trends
Hogaaminta soosaarayaasha Shiinaha, sida Fangda Kaarboon, ayaa gaadhay wax soo saar ballaaran oo ah φ800 mm uhp garaafyada korantada, oo ah 2030-kii korantada ee loo yaqaan 'Chiastord-ka's' oo ay ku kaceen cufnaanta kaarboon-ka-soo-baxa ee 89% Supercaacitors.
Falanqaynta Faa'iidada-Faa'iidada
Nidaamyada elektaroonigga ah ee biyaha, kahortaga kaarboon-ka-qaadayaasha ayaa bixiya kharashka maalgashiga bilowga ah ee kaliya 25% oo ah in la sameeyo korantada shaashadda laakiin waxay u baahan yihiin 30% dayactir sanadle ah oo sareeya. Waxaa si isdaba joog ah u sahmay, jaantusyada elektaroonigga ah, jaantusyada korantada oo keydi 50 kwood tan oo bir ah 1 dhirta mtpa, tarjumida keydka qiimaha sanadlaha ah ee ¥ 20 milyan.
6. Nolol farsamo ahaan
Tikniyoolajiyadda elektiroonite ee garaafka ah ayaa ku soo kordhaya 15% dhimista ka-hortagga iyada oo loo marayo nano-wax-ka-beddelka. Kaarboon electontrodes-ka waxaa lagu wanaajiyaa farsamooyinka isku-darka ah ee B-N si loo gaaro wanaajinta kuleylka illaa iyo 300 w / (m · k). Iyada oo laga jawaabayo xaraashka kaarboon EU kaarboon ee EU, warshadaha ayaa dardar gelinaya qaadashada kallifeynta tamarta ku saleysan tamarta, wadista kala duwanaanshaha farsamada.
