1.
Zopanda ZovutaGwiritsani ntchito madera okhala ndi ma sulfur oxides, chlorides, ndi mankhwala ena ankhanza. Silicon Carbide (SIC) ceramic akuwonetsa kukana kwa courrossion yolimbana ndi zinthu zosakwana 0.1% yothetsera miyeso mu PH 1-14 Njira (pa Asuri C863). Poyerekeza ndi chitsulo chosapanga dzimbiri (Pren 18-25) ndi Nickel Endos (Pren 30-40), a SEC 30-40), SEC 30-40.
2. Kukhazikika Kwambiri Kwambiri
Kutentha kwamatumba mu chonyowa gasi la fungu la fusi ulfurization nthawi zambiri kumazungulira 60-80 ° C ndi ma spikes opitilira 120 ° C. Sic ceramic imasunga 85% ya mphamvu yake yotentha kwambiri pa 1400 ° C, Kutulutsa kwa alumina cemiramics (kutaya 50% mphamvu ya 1000%. Mawonekedwe ake (120 w / mu · K · K) amathandizira kuchezera motentha, kupewa kupanikizika kwa matenthedwe.
3. Kuvala kukana
Ndili ndi vuto la maudindo a 28 GPA ndi kuwongolera pakati pa 4.6 MPAMEME¹ /, SIC ikutsutsana ndi kukongola kwa ntchentche (Mohs 5-7). Mayeso am'munda akuwonetsa ma noz ma noz <5% patatha 20,000 maola autumiki, poyerekeza ndi 30-40% amavala zitsulo zosakwana maola 8,000.
4. Mapangidwe
Kusasinthika kwa zomwe sizimachitika - zolumikizirana (kulumikizana ndi ngodya) Mawonekedwe ake osalala (ra 0.2-0.4μm) amachepetsa kupanikizika kwa 15-20% poyerekeza ndi zitsulo zokhazikika, ndikugwiritsa ntchito ma coult nthawi yayitali.
5. Kusavuta kusokonezeka
Kugwiritsa ntchito mankhwala a SIC kumalola njira zoyeretsa zoyeretsa kuphatikiza:
- ndege yamadzi yayikulu (mpaka 250 bar)
- Kuyeretsa ndi njira za alkaline
- steat srililization pa 150 ° C
Popanda chiopsezo cha kuchepa kwa mawonekedwe ofala mu ma polymer okhala ndi ma razle.
6.. Zachuma Zachuma
Ngakhale mitengo yoyambirira ya zisa za SIC ndi 2-3 × zapamwamba kuposa chitsulo chosapanga dzimbiri cha 316l. Mgwirizano wonsewo umawonetsa ma 40-60% ndalama zoposa zaka 10, ndi nthawi yopuma ya-iso.
7. Kuphatikizira chilengedwe
SIC imawonetsa kusakhala kosatsutsika kwambiri modabwitsa:
- Mafuta amchere kukana: 0% imasintha pambuyo pa 5000hr Astm B117 kuyezetsa
- Acid Dew Point Arct: Kuthana ndi 160 ° C H2SO4 Mipamba
- Kuzunza Kwambiri: Kupulumuka 1000 ° C → 25 ° C Overte
8. Katundu wotsutsa
Kapangidwe ka atomiki ya matomiki a sic kumapangitsa kuti zinthu zopanda pake zikhale zopumira 80% zotsika kuposa zitsulo zina. Kafukufuku wa Crystalogragraph akuwonetsa kuti ma secite ndi gypsum desikiti yofooka (mode <1 MPA) pa zitsulo: 5 m wapatali pa zitsulo, zomwe zimakulitsa njira yothetsera makina.
Kutha Kwaluso
Silicon Carbide imatuluka ngati njira yoyenera yodziwikiratu za FGD nozzles pakuwunika kokwanira:
- 10 × nthawi yayitali ntchito kuposa njira zina
- Kuchepetsa kwa 92% pakukonzedwa kosakonzekera
- 35% Kupititsa patsogolo kwambiri kuchotsedwa kwa nthawi yayitali
- kutsatira kwathunthu ndi CFR ya CFR GARE 63 Miyezo
Ndi njira zopangira zopanga ngati chifuwa chamadzi ndi ma cvd mozimba, zitseko zam'badwo zotsatira zikukwaniritsa zomwe zimamaliza kuchepa kwa micron micron. Chisinthiko chochokera ku chisinthiko ichi chimakhala ndi sinayi carbide ngati chinthu chosankha cha njira zotsutsira za m'badwo wotsatira.
