Tuubada shucaaca ee silikoon carbide

Iyada oo ah hal-abuure hormuud ka ah injineernimada dhoobada ee horumarsan, Shandong Zhongpeng Special Ceramics Co. Ltd waxay ku takhasustay soo saarista qiimaha sareAfka gubashada ee Silicon Carbide (RBSiC/SiSiC) oo leh falgal isku xirancodsiyada warshadaha ee heerkulka sare leh. Iyada oo la kaashanayo iskaashiyo la aasaasay oo ka kooban 20+ gobol oo Shiinaha ah, waxaan u adeegnaa sidii bixiye xalal kuleyl ah oo lagu kalsoon yahay oo loogu talagalay xarumaha wax soo saarka dhoobada ee waaweyn oo ay ku jiraan Aagga Warshadaha Ceramic ee Guangdong iyo Xarunta Wax soo saarka Ceramic ee Jiangsu.

Afkayaga gubashada carbide-ka ee silikoonku wuxuu bixiyaa waxqabad aan la barbar dhigi karin jawiga kulaylka aadka u daran iyada oo loo marayo:

- Qaboojiyaha kulaylka oo sareeya (140-180 W/m·K at 1000°C)

- Awood wareeg degdeg ah oo kulka ah (ΔT >1000°C/daqiiqo)

- Iska caabbinta oksaydhaynta ilaa 1600°C jawiga gubashada

- 3-5× cimri adeeg oo dheer marka loo eego beddelka caadiga ah ee aluminiumka

Codsiyada Kulaylka Warshadaha Isku-dhafan

Af-xidhka Zhongpeng ee saxda ah ee la farsameeyay wuxuu hagaajiyaa maaraynta kulaylka:

- Foornooyinka baabuurta lagu shito ee loogu talagalay dhoobada dhismaha

- Foornooyinka dabka lagu shido ee loogu talagalay soo saarista qalabka nadaafadda

- Foornooyinka tunnel-ka ee loogu talagalay sintering-ka walxaha birlabta ah

- Nidaamyada gubashada isku-dhafan (kuwa shidaalka laba-geesoodka ah ee gaaska/saliidda la jaanqaadaya)

Kala Duwanaanta Farsamada

- Wax soo saarka shahaadada ISO oo leh nidaamyada cadaadiska otomaatiga ah

- Joomatari la habeyn karo (Φ20-300mm, L = 100-2000mm)

- Xakamaynta qallafsanaanta dusha sare (Ra 0.4-3.2 μm)

- Raad-raac dufcadeed oo leh shahaado agab

Faa'iidooyinka Hawlgalka

- Awoodda wax soo saarka 24/7 ee dalabaadka degdegga ah

- Taageero farsamo oo goobta ah oo loogu talagalay dib-u-hagaajinta foornada

- Qiimo tartan leh oo leh qiimo dhimis mugga

- Barnaamijka hubinta tayada ee 18-bilood ah

Saamaynta Warshadaha ee La Xaqiijiyay

Tuubooyinkayaga gubashada RBSiC waxay muujiyeen horumar la qiyaasi karo oo ku saabsan:

- 15-20% isku mid ahaanshaha heerkulka oo la xoojiyay dhammaan aagagga foornada

- 30% hoos u dhac ku yimaada isticmaalka shidaalka iyada oo loo marayo gubasho la hagaajiyay

- 60% hoos u dhac ku yimid waqtiga shaqada ee beddelka af-xidhka

Shirkadda Shandong Zhongpeng Special Ceramics Co., Ltd waa mid ka mid ah xalalka ugu waaweyn ee walxaha cusub ee dhoobada ah ee silicon carbide ee Shiinaha. Dhoobada farsamada ee SiC: Adkaanshaha Moh waa 9 (adkeysiga New Moh waa 13), oo leh iska caabin aad u fiican oo ka dhan ah nabaad-guurka iyo daxalka, xoqid aad u fiican - iska caabin iyo ka-hortagga oksaydhka. Nolosha adeegga ee badeecada SiC waa 4 ilaa 5 jeer ka dheer 92% walxaha alumina. MOR ee RBSiC waa 5 ilaa 7 jeer ka badan SNBSC, waxaa loo isticmaali karaa qaabab badan oo adag. Habka xigashada waa mid degdeg ah, gaarsiintu waa sidii la ballanqaaday tayadana waa mid aan la barbar dhigi karin. Had iyo jeer waxaan ku adkaysannaa inaan ka hortagno yoolalkayaga oo aan qalbiyadeenna dib ugu celinno bulshada.
