Valani chitoliro cha ceramic cholimba cha Silicon carbide
Silikoni carbide ceramic: Kulimba kwa Moh ndi 9.0 ~ 9.2, ndi kukana bwino kukokoloka ndi dzimbiri, kukana kukwawa komanso kukana okosijeni. Ndi wamphamvu nthawi 4 mpaka 5 kuposa nitride bonded silicon carbide. Nthawi yogwira ntchito ndi yayitali nthawi 7 mpaka 10 kuposa alumina material. MOR ya RBSiC ndi nthawi 5 mpaka 7 kuposa ya SNBSC, ingagwiritsidwe ntchito pamitundu yovuta kwambiri.
Kukana kwa Silicon Carbide, komwe kumapangidwa kuchokera ku Silicon Carbide ndi Carbon pa kutentha kwambiri, ndi kwa mtundu wa chinthu cha Silicon Carbide. Zigawo za Silicon Carbide Variable Resistance zimagwiritsidwa ntchito kwambiri mu migodi, kuphwanya miyala, kufufuza ndi kunyamula zinthu zowononga kwambiri, komanso zoyenera kwambiri pazinthu zamakanika zomwe zimafunikira molondola kwambiri komanso kusindikiza, monga pampu yamagetsi, pampu yamaginito ndi zina zotero. Ndi mtundu watsopano wa zinthu zotsutsana ndi kuvala. Silicon Carbide Variable Reaction-bonded Silicon Carbide Variable Reaction ili ndi makhalidwe a kuuma kwambiri, kukana kwa kuvala kwambiri, kukana kukhudza, kukana kutentha kwambiri, kukana kwa asidi ndi alkali ndi zina zotero, ndipo moyo weniweni wautumiki ndi woposa nthawi 6 kuposa wa polyurethane. Ndi yoyenera kwambiri kugwiritsa ntchito magulu, kuyika ndi kutaya madzi m'thupi kwa zinthu zolimba komanso zosalala, zagwiritsidwa ntchito bwino m'migodi yambiri. Kampani yathu ndi kampani yaukadaulo yopereka zinthu za ceramic zotsutsana ndi kuvala za silicon Carbide, kuuma kwachiwiri pambuyo pa diamondi, yokhala ndi kukana kwa kuvala kwambiri, komanso nthawi yayitali yautumiki. Chitoliro chokana kuvala ndi chigongono chomwe chimapangidwa ndi silicon Carbide Variable Resistance Lining, makulidwe ake a ceramic linear ndi 6-35mm, kapangidwe kake ndi kokhazikitsa kale. Chitoliro cha ceramic chopindidwa mu chubu chachitsulo chofanana, ndi guluu pakati. Mapaipi a ceramic okana kuvala ali ndi makhalidwe otsatirawa poyerekeza ndi mapaipi am'mbuyomu a miyala yopangidwa ndi miyala, mapaipi achitsulo opangidwa ndi alloy osatha kuvala ndi mapaipi a ceramic composite.
Silikoni carbide yolumikizidwa ndi reaction (RBSC) ili ndi mawonekedwe abwino kwambiri osawonongeka, ili ndi makhalidwe abwino kutentha kwambiri, kukokoloka bwino komanso kukana kukwiya, makhalidwe amenewa angagwiritsidwe ntchito m'njira zosiyanasiyana monga mapaipi, chigongono cha ceramic, ma nozzles opopera, ma nozzles ophulika ndi zida za hydrocyclone.
ZPC zili ndi ma linens okhazikika kwambiri kuposa matailosi ndi zitsulo. ZPC silicon carbide ceramics zimalimbana ndi kutentha komanso zimalimbana ndi kugwedezeka komwe kumabweretsa nthawi yayitali yogwirira ntchito komanso kuchepa kwa nthawi yogwira ntchito.
Siliyoni carbide ceramic yolumikizidwa ndi reaction (RBSIC) ndi chinthu chabwino kwambiri cholimba, chomwe chimagwira ntchito bwino kwambiri polimbana ndi zinthu zokhuthala, tinthu tating'onoting'ono, kugawa, kuchuluka kwa madzi m'thupi, ndi zina zotero. Chifukwa cha makhalidwe omwe ali pamwambapa,RBSiC / SiSiC silicon carbide liner elbow / liner chubuimatha kuteteza bwino gawolo ku kuwonongeka kwambiri komanso kutentha kwambiri kuti iwonjezere nthawi yogwira ntchito ya chipangizocho.

Mkhalidwe wogwirira ntchito wa chitoliro cholimba cha silicon carbide ceramic
Makhalidwe abwino a silicon carbide ndi awa:
- Kuchuluka kochepa
- Mphamvu yayikulu
- Mphamvu yabwino yotentha kwambiri (Yogwirizana ndi kuyankha)
- Kukana kwa okosijeni (Kuchitapo kanthu kogwirizana)
- Kukana bwino kutentha kwa kutentha
- Kuuma kwambiri ndi kukana kuvala
- Kukana kwabwino kwambiri kwa mankhwala
- Kukulitsa kutentha kochepa komanso kutentha kwambiri
Magwiritsidwe ntchito a silicon carbide ndi awa:
Amagwiritsidwa ntchito kwambiri pogwira ntchito ndi kutentha kochepa kuposa kutentha kwambiri. Ma SiC ogwiritsidwa ntchito ndi monga ma injector ophulitsa mchenga, zomatira za pampu yamadzi yamagalimoto, ma bearing, zigawo za pampu, ndi ma extrusion dies omwe amagwiritsa ntchito kuuma kwambiri, kukana kukwawa, komanso kukana dzimbiri kwa carbide ya silicon.
- Zigawo za turbine zokhazikika komanso zosuntha
- Zisindikizo, mabearing, ma vane a pampu
- Zigawo za valavu ya mpira
- Valani mbale
- Mipando ya uvuni
- Zosinthira kutentha
- Zipangizo zopangira wafer wa semiconductor
Makampani opanga zitsulo ndi magetsi: Chifukwa chomwe mafakitale awiriwa amapangidwira pamodzi makamaka ndi chifukwa chakuti mafakitale awiriwa ali ndi
Shandong Zhongpeng Special Ceramics Co., Ltd ndi imodzi mwa njira zazikulu kwambiri zothetsera zinthu zatsopano za silicon carbide ceramic ku China. SiC technical ceramic: Kuuma kwa Moh ndi 9 (Kuuma kwa New Moh ndi 13), komwe kumalimbana bwino ndi kukokoloka ndi dzimbiri, kukana bwino kwambiri - kukana komanso kukana okosijeni. Moyo wa ntchito wa SiC ndi wautali nthawi 4 mpaka 5 kuposa 92% alumina. MOR ya RBSiC ndi nthawi 5 mpaka 7 kuposa ya SNBSC, ingagwiritsidwe ntchito pazinthu zovuta kwambiri. Njira yowerengera mawu ndi yachangu, kutumiza kumakhala monga momwe kunalonjezera ndipo khalidwe lake ndi lapamwamba kwambiri. Nthawi zonse timapitilizabe kutsutsa zolinga zathu ndikubwezera mitima yathu kwa anthu.
