Ma tray a ceramic a Silicon carbide (SiC) ndi zinthu zogwira ntchito kwambiri zomwe zimagwiritsidwa ntchito kwambiri m'malo otentha kwambiri, odzaza kwambiri, komanso ovuta kwambiri m'mafakitale. Opangidwa kuchokera ku zipangizo zapamwamba za ceramic za silicon carbide, ma tray awa adapangidwa kuti apereke mphamvu yamakina yabwino kwambiri, kutentha kwapamwamba kwambiri, komanso kukana kutentha kwambiri, okosijeni, ndi dzimbiri. Kulimba kwawo kumawapangitsa kukhala oyenera kwambiri ntchito zosiyanasiyana zamafakitale kuphatikizapo kupanga ma semiconductor, kukonza ma photovoltaic, kusungunula magawo a zitsulo za ufa, ndi zina zambiri.

Mathireyi a silicon carbide amagwira ntchito ngati zonyamulira zofunika kapena zothandizira panthawi yokonza kutentha komwe kulondola kwa miyeso, kulimba kwa kapangidwe kake, komanso kukana mankhwala ndikofunikira kwambiri. Poyerekeza ndi zipangizo zachikhalidwe zadothi monga alumina kapena mullite, mathireyi a SiC amapereka magwiridwe antchito apamwamba kwambiri, makamaka m'mikhalidwe yomwe ikuphatikizapo kutentha kobwerezabwereza komanso mlengalenga woopsa.

Njira Yopangira & Kapangidwe ka Zinthu

Kupanga mathireyi a SiC ceramic kumaphatikizapo uinjiniya wolondola komanso ukadaulo wapamwamba wopangira sintering kuti zitsimikizire kuchuluka kwa zinthu, kapangidwe kake kofanana, komanso magwiridwe antchito okhazikika. Masitepe onsewa ndi awa:

Kusankha Zinthu Zopangira
Ufa wa silicon carbide woyeretsedwa kwambiri (≥99%) umasankhidwa, nthawi zambiri umakhala ndi mawonekedwe apadera a tinthu tating'onoting'ono komanso zodetsa zochepa kuti zitsimikizire kuti makina ndi kutentha zimakhala ndi mphamvu zambiri.
Njira Zopangira
Malinga ndi mawonekedwe a thireyi, njira zosiyanasiyana zopangira thireyi zimagwiritsidwa ntchito:
- Kukanikiza Kozizira Kosakhazikika (CIP) kwa ma compacts okhala ndi kuchuluka kwakukulu komanso kofanana
- Kutulutsa kapena kuponyera zinthu mozungulira mawonekedwe ovuta
- Kuumba jakisoni kuti mupeze ma geometries olondola komanso atsatanetsatane
Njira Zoyeretsera
Thupi lobiriwira limatenthedwa kutentha kwambiri, nthawi zambiri pa kutentha kwa madigiri 2000 Celsius, pansi pa mpweya wopanda mpweya kapena vacuum. Njira zodziwika bwino zotenthetsera ndi izi:
- SiC Yogwirizana ndi Reaction (RB-SiC)
- SiC Yopanda Kupanikizika (SSiC)
- SiC Yobwezeretsedwanso (RBSiC)
  Njira iliyonse imabweretsa zinthu zosiyana pang'ono, monga porosity, mphamvu, ndi kutentha.
Kukonza Machining Mwanzeru
Pambuyo poyatsa, mathireyi amapangidwa kuti azitha kupirira bwino, kusalala bwino, komanso kukhala osalala. Mankhwala ochizira pamwamba monga kupala, kupukuta, ndi kupukuta angagwiritsidwe ntchito kutengera zosowa za makasitomala.

Mapulogalamu Odziwika

Ma tray a ceramic a silicon carbide amagwiritsidwa ntchito m'mafakitale osiyanasiyana chifukwa cha kusinthasintha kwawo komanso kulimba kwawo. Ntchito zodziwika bwino zimaphatikizapo:

Makampani Opanga Makontrakitala
Ma tray a SiC amagwiritsidwa ntchito ngati zonyamulira panthawi yothira mafuta, kufalitsa, kusungunuka, kuyika mafuta m'thupi, ndi kuyika zinthu m'thupi. Kukhazikika kwawo kumatsimikizira kufalikira kwa kutentha kofanana komanso kuchepa kwa kuipitsidwa.
Makampani a Photovoltaic (PV)
Pakupanga maselo a dzuwa, ma tray a SiC amathandizira ma ingot a silicon kapena ma wafer panthawi yofalikira kwambiri komanso yowotcha.
Ufa wa Zitsulo ndi Zoumbaumba
Amagwiritsidwa ntchito pothandizira zigawo zina poyeretsa ufa wachitsulo, zoumbaumba, ndi zinthu zophatikizika.
Magalasi ndi Ma Panel Owonetsera
Amagwiritsidwa ntchito ngati mathireyi a uvuni kapena nsanja zopangira magalasi apadera, ma LCD substrates, kapena zida zina zowunikira.
Kukonza Mankhwala ndi Matenthedwe
Amagwira ntchito ngati zonyamulira zosagwirizana ndi dzimbiri m'ma reactor a mankhwala kapena ngati mathireyi othandizira kutentha m'mauvuni otayira mpweya ndi mlengalenga wolamulidwa.

Zinthu Zofunika Kwambiri Zogwira Ntchito

✅Kukhazikika Kwambiri kwa Kutentha
Imapirira kugwiritsidwa ntchito mosalekeza kutentha mpaka 1600–2000°C popanda kupindika kapena kuwonongeka.
✅Mphamvu Yapamwamba Yamakina
Imapereka mphamvu yolimba kwambiri (nthawi zambiri >350 MPa), kuonetsetsa kuti imakhala yolimba kwa nthawi yayitali ngakhale ikagwiritsidwa ntchito kwambiri.
✅Kukana Kugwedezeka kwa Kutentha
Kuchita bwino kwambiri m'malo omwe kutentha kumasinthasintha mofulumira, kuchepetsa chiopsezo cha ming'alu.
✅Kukana kwa dzimbiri ndi okosijeni
Yokhazikika mu ma acid ambiri, ma alkali, ndi mpweya wochepetsa okosijeni, yoyenera kugwiritsidwa ntchito pa mankhwala oopsa.
✅Kulondola ndi Kusalala kwa Miyeso
Makina opangidwa mwaluso kwambiri, kuonetsetsa kuti zinthu zikugwiritsidwa ntchito mofanana komanso mogwirizana ndi makina odzipangira okha.
✅Kutalika kwa Moyo Wautali & Kugwiritsa Ntchito Ndalama Mwanzeru
Kutsika kwa mitengo yosinthira ndi kuchepetsa ndalama zokonzera kumapangitsa kuti ikhale njira yotsika mtengo pakapita nthawi.

Mafunso Ofunsidwa Kawirikawiri (Mafunso Ofunsidwa Kawirikawiri)

Q1: Kodi ma tray a silicon carbide angagwiritsidwe ntchito mu uvuni wa vacuum?
A:Inde, mathireyi a SiC ndi abwino kwambiri m'malo opanda mpweya chifukwa cha mpweya wochepa, kukhazikika kwa mankhwala, komanso kukana kutentha kwambiri.

Q2: Kodi pali mawonekedwe kapena mipata yopangidwa mwamakonda?
A:Inde. Timapereka ntchito zosintha zinthu kuphatikizapo kukula kwa thireyi, mawonekedwe, mawonekedwe a pamwamba (monga mipata, mabowo), ndi kupukuta pamwamba kuti tikwaniritse zosowa za makasitomala.

Q3: Kodi SiC imafanana bwanji ndi alumina kapena quartz trays?
A:SiC ili ndi mphamvu zambiri, kutentha kwabwino, komanso kukana kutentha kwambiri komanso dzimbiri la mankhwala. Ngakhale alumina ndi yotsika mtengo, SiC imagwira ntchito bwino m'malo ovuta.

Q4: Kodi pali makulidwe ofanana a mathireyi awa?
A:Kukhuthala kwake nthawi zambiri kumakhala pakati pa 5–20 mm, koma tikhoza kusintha kutengera momwe mukugwiritsira ntchito komanso zomwe mukufuna kunyamula.

Q5: Kodi nthawi yodziwika bwino yoperekera mathireyi a SiC okonzedwa ndi iti?
A:Nthawi yotsogolera imasiyana malinga ndi zovuta ndi kuchuluka koma nthawi zambiri imatenga milungu iwiri mpaka inayi kuti maoda akonzedwe.

Zambiri zaife

XKH imagwira ntchito kwambiri pakupanga, kupanga, ndi kugulitsa magalasi apadera a kuwala ndi zinthu zatsopano zamakristalo. Zogulitsa zathu zimapereka zinthu zamagetsi, zamagetsi, ndi zankhondo. Timapereka zinthu za Sapphire optical, zophimba ma lens a foni yam'manja, Ceramics, LT, Silicon Carbide SIC, Quartz, ndi ma crystal wafers a semiconductor. Ndi ukatswiri waluso komanso zida zamakono, timachita bwino kwambiri pokonza zinthu zosakhazikika, cholinga chathu ndi kukhala kampani yotsogola kwambiri yaukadaulo wamagetsi.
