Njerwa za Silicon Carbide
Zambiri Zamalonda
Silicon carbide njerwandi refractory zinthu zopangidwa silicon carbide (SiC) monga zopangira zazikulu. Ili ndi mawonekedwe a kuuma kwakukulu, kukana kuvala kwambiri, kukhathamiritsa kwamafuta ambiri komanso kukana kwa dzimbiri. Chigawo chake chachikulu ndi silicon carbide, ndipo zomwe zili mkati nthawi zambiri zimakhala pakati pa 72% ndi 99%. Mitundu yodziwika bwino imaphatikizapo njerwa za silicon carbide za dongo, njerwa za silicon nitride zomangika za silicon carbide, njerwa za Sialon-bonded silicon carbide, ndi zina zambiri.
1. Makhalidwe
Kuuma kwakukulu:Kulimba kwa Mohs kwa njerwa za silicon carbide ndi 9, ndipo imakhala yolimba kwambiri.
High matenthedwe conductivity:Lili ndi matenthedwe apamwamba kwambiri ndipo ndi oyenera nthawi zomwe zimafuna kutentha kwachangu.
Kulimbana ndi corrosion:Ili ndi kukhazikika kwa acidic slag ndipo ndiyoyenera kumadera osiyanasiyana otentha komanso kuwononga mankhwala.
Thermal shock resistance:Ili ndi mphamvu yabwino ya kutentha kwa kutentha ndipo imatha kukhala yokhazikika pansi pa kusintha kwachangu kwa kutentha.
2. Gulu
Njerwa za silicon carbide zitha kugawidwa m'magulu otsatirawa motengera njira zosiyanasiyana zomangira:
Njerwa za silicon carbide zomangidwa ndi dongo:Dongo limagwiritsidwa ntchito ngati chomangira, choyenera pazochitika zomwe zimafuna kutenthetsa kwambiri komanso kukana kugwedezeka kwamafuta.
Njerwa za silicon nitride zomangika ndi silicon carbide:kuthamangitsidwa ndi nitriding reaction, yokhala ndi kukhazikika kwakukulu kwa kutentha komanso kukana kuvala.
Njerwa za silicon carbide zomangidwa ndi Sialon:kuphatikiza ndi Si3N4 ndi Al2O3 ufa, oyenera kutentha kwambiri ndi dzimbiri chilengedwe mankhwala.
Njerwa zowonjezeredwa za silicon carbide:okonzeka kudzera njira recrystallization, ndi mphamvu mkulu ndi kukana zabwino kuvala.
Tsatanetsatane Zithunzi
Kukula ndi mawonekedwe zitha kusinthidwa malinga ndi zomwe makasitomala amafuna !!!

Kugwiritsa ntchito
Njerwa za silicon carbidekukhala ndi machulukidwe apamwamba amafuta, kusamva bwino, kukana kugwedezeka kwamafuta, komanso kukana kukokoloka. Chifukwa chake, njerwa za silicon carbide zimagwiritsidwa ntchito kwambiri m'mafakitale.
1. Lining, nozzles, plugs of metallurgical steel cylinders, ng'anjo yophulika pansi ndi mimba, ndi njanji zopanda madzi za ng'anjo zowotcha;
2. Non-ferrous zitsulo smelting distiller, distillation nsanja thireyi, electrolytic cell mbali khoma, smelting zitsulo crucible;
3. Mashelufu ndi zipangizo zotchinjiriza lawi la ng'anjo zamafuta a silicate;
4. Mafuta ndi gasi jenereta ndi organic zinyalala kuyaka ng'anjo mu makampani mankhwala;
5. Zida zamakono zopangira ng'anjo ya aluminiyamu electrolytic cell lining, zitsulo zosungunuka za aluminiyamu ndi mipando ya ceramic, m'munsi mwa ng'anjo yayikulu ndi yapakati, m'chiuno cha ng'anjo ndi mimba ya ng'anjo, aluminiyamu yoyenga ng'anjo, zinki distillation tank lining, etc.
Phukusi & Malo Osungira
Mbiri Yakampani
Malingaliro a kampani Shandong Robert New Material Co., Ltd.ili mu Zibo City, Province Shandong, China, amene ndi refractory zinthu kupanga m'munsi. Ndife makampani amakono omwe amaphatikiza kafukufuku ndi chitukuko, kupanga, kugulitsa, kapangidwe ka ng'anjo ndi zomangamanga, ukadaulo, ndi zida zotumizira kunja. Tili ndi zida zonse, ukadaulo wapamwamba, mphamvu zolimba zaukadaulo, mtundu wabwino kwambiri wazinthu, komanso mbiri yabwino. Fakitale yathu imakhala ndi maekala opitilira 200 ndipo zotulutsa zowoneka bwino zowoneka bwino zimakhala pafupifupi matani 30000 ndipo zida zosapanga dzimbiri ndi matani 12000.
Zogulitsa zathu zazikulu za zida za refractory ndi:zinthu zamchere refractory; zotayidwa silicon refractory zipangizo; zinthu zosapanganika zokanira; kutchinjiriza matenthedwe refractory zipangizo; zida zapadera zokanira; zinchito refractory zipangizo mosalekeza kuponya kachitidwe.
Mafunso Ofunsidwa Kawirikawiri
Mukufuna thandizo? Onetsetsani kuti mwayendera mabwalo athu othandizira kuti mupeze mayankho a mafunso anu!
Ndife opanga zenizeni, fakitale yathu ndi yapadera popanga zida zokanira kwa zaka zopitilira 30. Timalonjeza kupereka mtengo wabwino kwambiri, ntchito yabwino kwambiri yogulitsiratu komanso yogulitsa pambuyo pake.
Panjira iliyonse yopanga, RBT ili ndi dongosolo lathunthu la QC la kapangidwe kake ndi zinthu zakuthupi. Ndipo tidzayesa katunduyo, ndipo chiphaso chabwino chidzatumizidwa ndi katunduyo. Ngati muli ndi zofunikira zapadera, tidzayesetsa kuti tikwaniritse.
Malingana ndi kuchuluka kwake, nthawi yathu yoperekera ndi yosiyana. Koma tikulonjeza kutumiza mwamsanga ndi khalidwe lotsimikizika.
Inde, timapereka zitsanzo zaulere.
Inde, ndithudi, ndinu olandiridwa kukaona RBT kampani ndi katundu wathu.
Palibe malire, titha kukupatsani malingaliro ndi yankho labwino kwambiri malinga ndi momwe mulili.
Takhala tikupanga zida zokanira kwazaka zopitilira 30, tili ndi chithandizo champhamvu chaukadaulo komanso chidziwitso cholemera, titha kuthandiza makasitomala kupanga ma kilns osiyanasiyana ndikupereka ntchito imodzi.
