Kufotokozera kwa Corundum Mullite Castable
Corundum mullite refractory castable ndi mtundu wa zipangizo zolimba zosaoneka bwino zomwe zimagulitsidwa ku RS Company, zomwe zingagwiritsidwe ntchito mu uvuni wa simenti. Corundum mullite castables zimatha kuchita zinthu zambiri monga kulimba kwambiri, kukhazikika kutentha, kukana kutentha, kukana kuwonongeka kwa mankhwala m'kati mwa boiler yayikulu yamagetsi ndi zida zina zotentha kwambiri. Corundum mullite refractory castable ingagwiritsidwe ntchito mu uvuni wachitsulo, uvuni wa simenti, uvuni wagalasi, uvuni wopanga chitsulo, uvuni wa ceramic tunnel ndi zina zotero.
Katundu wa Corundum Mullite Castable
- Mphamvu yayikulu,
- Kukana kuvala mwamphamvu,
- Kukana kukokoloka kwa nthaka bwino,
- Kukhazikika kwabwino kwambiri kwa kutentha,
- Kukana kutentha kwambiri.
Njira Yopangira Corundum Mullite Castable
Zipangizo zazikulu zopangira corundum mullite castable ndi aluminiyamu yopepuka, miyala yamtengo wapatali ya mullite, ndi simenti ya calcium aluminate ngati cholumikizira. corundum mullite refractory castable imapangidwa kudzera mu kutentha kwambiri ndi ng'anjo yapamwamba yamafakitale. mphamvu yosinthasintha ya corundum mullite ndi mphamvu yokakamiza zimawonjezeka kaye ndikuchepa kenako ndi kuwonjezeka kwa kutentha kwa chithandizo cha kutentha. Ndipo mphamvu ya alumina ikakhala 5%, mphamvu yosinthasintha imafika pamwamba.
Kuphatikizika kwa Corundum Mullite Castable
Zomwe zili mu Al2O3 ndi zoposa 90%, ndipo corundum mullite insulation castable ndi corundum monga gawo lalikulu la kristalo zimasakanizidwa ndi dispersants zoyenera, coagulants, ulusi wosapanga dzimbiri, zomwe zimaphatikizidwa motsatira njira yokhwima. Refractory corundum mullite castable ili ndi makhalidwe ambiri, monga mphamvu yotentha kwambiri, kukana kuwonongeka ndi kuipitsidwa, kutentha kwambiri, kukana kutentha, kukana dzimbiri, kutseka bwino komanso kuzizira koyambirira.

Kugwiritsa ntchito Corundum Mullite Castable
Corundum mullite refractory castable ili ndi mawonekedwe ofanana a kukula, kukana kutentha kwambiri, kukhazikika kwa voliyumu yotentha kwambiri, mphamvu yotentha kwambiri, kukana kwambiri pansi pa katundu, kutsika kwa kutentha kwambiri, mphamvu yophwanya kwambiri, kusintha kwa mawonekedwe otsika, kuuma kwakukulu, kukana bwino dzimbiri la mankhwala, kukana kutayika ndi kuvala. Chifukwa cha zilembo zotere, corundum mullite insulation castable ndi yolimba ndipo imagwiritsidwa ntchito kwambiri mu uvuni wa mafakitale osiyanasiyana, ng'anjo yotentha kwambiri ndi zina zofunika kwambiri kutentha kwambiri, monga:
- Boiler, ng'anjo yophulika, chitofu chotentha, ng'anjo yotenthetsera,
- Uvuni wa ngalande ya ceramic, uvuni wa simenti, chotenthetsera malasha,
- Chitseko cha ng'anjo, kutsegula chakudya, ng'anjo zachitsulo, ng'anjo zopangira chitsulo,
- Chipinda choyaka moto, chitoliro chopendekeka,
- Boiler yaikulu ya siteshoni yamagetsi, uvuni wagalasi.
