Kugwiritsa ntchito ng'oma ya Silicon Carbide ceramic pogaya potentha
Silicon carbide ceramic akupera mbiya wakhala zopangira cathode chuma lifiyamu batire chifukwa chofunika conductive katundu.SiC heat element ndi chinthu chofunikira kwambiri pa zinthu za SiC ndipo chili ndi chiyembekezo chamsika waukulu.
Silicon carbide akupera mbiya mwayi
(1) Mphamvu zamakina apamwamba, zabwino ngati
Mphamvu zamakina zapamwamba zimatha kuteteza kusinthika kwa zinthu, zomwe ndizofunikira kwambiri.Silicon carbide ili ndi mphamvu zamakina apamwamba kuposa corundum.Mwachitsanzo, mphamvu yopondereza ya silicon carbide ndi 224MPa, pomwe ya corundum ndi 75.7MPa yokha.Mphamvu yopindika ya silicon carbide ndi 15.5MPa, ndipo ya corundum ndi 8.72MPa.
(2) Kukana kutentha kwakukulu, coefficient yaing'ono ya kuwonjezeka kwa kutentha
Silicon carbide amapangidwa pa kutentha kwambiri.M'malo ena otentha kwambiri, zinthuzo zimafunika kuti zikhale ndi mphamvu zina zogwirira ntchito, ndikukwaniritsa kulondola kwa kukonza, ndi zoumba za silicon carbide zimatha kukwaniritsa mfundo ziwirizi.Kutentha kwambiri kwa silicon carbide ndi pafupifupi 800 ℃, ndipo kutentha kwachitsulo ndi 250 ℃ kokha.Powerengera movutikira, kuchuluka kwa kutentha kwapakati kwa SIC ndi 4.4 × 10-6/ C mumitundu ya 25 ~ 1400 ℃.Kuchulukitsa kwamafuta a SIC ndikocheperako kuposa ma abrasives ena ndi zida zotentha kwambiri.Mwachitsanzo, coefficient of thermal expansion of corundum ingakhale yokwera ngati (7~8) × 10-6/℃.
(3) Kukana dzimbiri
Silicon carbide chifukwa cha kusungunuka kwake (kutentha kwa kutentha), inertia yamankhwala ndi kukana kwamphamvu kwamphamvu, imatha kugwiritsidwa ntchito pazinthu zosiyanasiyana za silicon carbide ceramic, monga zida za ceramic zopangira ng'anjo yamoto, mbale ya denga ndi sagger, zinki zosungunula mafakitale zowongoka. ng'anjo ya cylinder distillation yokhala ndi njerwa ya silicon carbide, aluminium electrolytic cell lining, crucible, ng'anjo yaying'ono.
Kugwiritsa ntchito Corrosion resistance
1, Magawo otsetsereka (chisindikizo cha makina, pampu yamankhwala, shaft)
2, Chalk Crusher (classifier, mpweya mphero, mchenga mphero)
3.Semiconductor zopangira zida mbali (XY nsanja, MOCVD thireyi, molunjika mphete, yopyapyala chuck)
4. Magawo a makina opangira (mbali za makina opangira magalasi a kamera)
5. Zigawo zosagwirizana ndi kutentha (nozzle yoyaka moto, zida zamakina zoyezera kutentha kwambiri, chitsulo chosungunula)
6. Ziwalo zosamva kuvala (nozzle ya makina oboola mchenga, chowombera chowombera makina opukutira, mbale yoteteza mapaipi okwiriridwa, mphete yolozera nsomba)

FAQ
Q: Kodi mumagulitsa kampani kapena wopanga?
A: Ndife fakitale yopitilira 10 ya vears yokhala ndi certification ya iso9001
Q: Kodi nthawi yanu yobereka imatenga nthawi yayitali bwanji?
A: Nthawi zambiri ndi masiku 3-5 ngati katundu ali m'gulu, kapena masiku 10-15 ngati katunduyo mulibe, ndi malinga ndi kuchuluka kwanu.
Q: Kodi Iget chitsanzo kuona khalidwe lanu?
A: Pambuyo kutsimikizira mtengo, mungafunike zitsanzo kuti muone khalidwe la mankhwala athu.Ngati mukungofuna chitsanzo chopanda kanthu kuti muwone kapangidwe kake ndi mtundu wake, tidzakupatsani zitsanzo zaulere bola mungakwanitse kunyamula katundu.
Q: Kodi malipiro anu ndi otani?
A: Timavomereza malipiro a Western Union, Pavpal, Alibaba, T/TL/Cetc.for chochuluka, timachita 30% deposit balance tisanatumize.
ngati muli ndi funso lina, pls omasuka kulankhula nafe monga pansipa.
Chifukwa chiyani mungasankhe Wei Tai?
1) tili ndi chitsimikizo chokwanira chamasheya.
2) ma CD akatswiri amatsimikizira kukhulupirika kwa mankhwala.Chogulitsacho chidzaperekedwa kwa inu mosamala.
3) mayendedwe ochulukirapo amathandizira kuti zinthu ziziperekedwa kwa inu.
