Cholinga chathu chachikulu ndikupatsa makasitomala athu ubale wodalirika komanso wodalirika, kuwapatsa chisamaliro chapadera kuti ayang'anire Ubwino wa China Hot Sale High Quality Customized Metal Melting Graphite Ingot Mold, Timalandira bwino abwenzi apamtima ochokera m'mitundu yonse ya moyo watsiku ndi tsiku kuti agwirizane ndikupanga tsogolo labwino komanso lokongola.
Cholinga chathu chachikulu ndikupatsa makasitomala athu ubale wabwino komanso wodalirika wa bizinesi, kuwapatsa chisamaliro chapadera kwa onse.China Yopitiriza Kutaya Graphite Jig, Wozungulira Wokutira Graphite Nkhungu, Tikulandira mwayi wochita bizinesi nanu ndipo tikukhulupirira kuti tidzakhala okondwa kukupatsani zambiri zokhudza zinthu zathu ndi mayankho athu. Ubwino wabwino kwambiri, mtengo wopikisana, kutumiza nthawi yake komanso ntchito yodalirika zitha kutsimikizika. Kuti mudziwe zambiri chonde musazengereze kutilumikizana nafe.
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.
