Pogwiritsa ntchito njira yoyendetsera zinthu zabwino kwambiri, khalidwe lapamwamba komanso chikhulupiriro chabwino, tapeza dzina labwino kwambiri ndipo tagwira ntchito m'munda uno wogulitsira ku China. China Wopanga Graphite Crucible/Boat Wapamwamba, tikhoza kuthetsa mavuto a makasitomala athu mwachangu ndikupeza phindu kwa makasitomala athu. Kwa iwo omwe akufuna wopereka wabwino komanso wabwino kwambiri, chonde tisankheni, zikomo!
Pogwiritsa ntchito njira yonse yasayansi yoyendetsera bwino zinthu, khalidwe lapamwamba komanso chikhulupiriro chabwino, timapeza dzina labwino ndipo timagwira ntchito m'munda uno.China Crucible, Chophimba cha Graphite, tili ndi mzere wathunthu wopanga zinthu, mzere wopangira zinthu, makina owongolera khalidwe, ndipo chofunika kwambiri, tili ndi ukadaulo wambiri wa ma patent komanso gulu lodziwa bwino ntchito zaukadaulo ndi kupanga zinthu, gulu la akatswiri ogulitsa. Ndi ubwino wonsewu, takhala tikukonzekera kupanga "mtundu wodziwika bwino wapadziko lonse wa nylon monofilaments", ndikufalitsa zinthu zathu kumakona onse a dziko lapansi. Takhala tikupitilizabe ndikuyesetsa kutumikira makasitomala athu.
Zosakaniza za kaboni / kaboni(pano akutchedwa "C / C kapena CFC”) ndi mtundu wa zinthu zopangidwa ndi kaboni zomwe zimachokera ku kaboni ndipo zimalimbikitsidwa ndi ulusi wa kaboni ndi zinthu zake (preform ya ulusi wa kaboni). Ili ndi mphamvu ya kaboni komanso mphamvu yayikulu ya ulusi wa kaboni. Ili ndi mphamvu zabwino zamakaniko, kukana kutentha, kukana dzimbiri, kukana kukangana komanso mawonekedwe a kutentha ndi magetsi.
CVD-SiCChophimbacho chili ndi mawonekedwe ofanana, zinthu zazing'ono, kukana kutentha kwambiri, kukana okosijeni, kuyera kwambiri, kukana asidi ndi alkali ndi reagent yachilengedwe, yokhala ndi katundu wokhazikika wakuthupi ndi wamakemikolo.
Poyerekeza ndi zinthu za graphite zoyera kwambiri, graphite imayamba kusungunuka pa 400C, zomwe zimapangitsa kuti ufa utayike chifukwa cha kusungunuka, zomwe zimapangitsa kuti zinthu zozungulira ndi zipinda zotsukira ziwonongeke, ndikuwonjezera zinyalala za malo oyera kwambiri.
Komabe, chophimba cha SiC chimatha kusunga bata la thupi ndi mankhwala pa madigiri 1600, ndipo chimagwiritsidwa ntchito kwambiri m'makampani amakono, makamaka m'makampani opanga ma semiconductor.
Kampani yathu imapereka ntchito zophimba za SiC pogwiritsa ntchito njira ya CVD pamwamba pa graphite, ceramics ndi zinthu zina, kotero kuti mpweya wapadera wokhala ndi kaboni ndi silicon umagwira ntchito kutentha kwambiri kuti upeze mamolekyu a SiC oyera kwambiri, mamolekyu omwe amaikidwa pamwamba pa zinthu zophimbidwa, ndikupanga gawo loteteza la SIC. SIC yopangidwayo imalumikizidwa mwamphamvu ku maziko a graphite, zomwe zimapatsa maziko a graphite mawonekedwe apadera, motero zimapangitsa pamwamba pa graphite kukhala pang'ono, yopanda Porosity, yokana kutentha kwambiri, yokana dzimbiri komanso yokana okosijeni.
Zinthu zazikulu:
1. Kukana kutentha kwambiri kwa okosijeni:
Kukana kwa okosijeni kumakhala bwino kwambiri pamene kutentha kuli pamwamba pa 1600 C.
2. Kuyera kwambiri: kumapangidwa ndi nthunzi ya mankhwala pansi pa kutentha kwambiri kwa chlorination.
3. Kukana kukokoloka kwa nthaka: kuuma kwambiri, pamwamba pang'ono, tinthu tating'onoting'ono.
4. Kukana dzimbiri: asidi, alkali, mchere ndi zinthu zachilengedwe.
