Chipika cholimba cha alkali ndi mtundu wa njerwa zochepa za alumina, kuchuluka kwa Al2O3 ndi 30-25%, zinthu zazikulu zomwe zimapangidwa ndi zipika zolimba za alkali ndi dongo lolimba la alumina lochepa, chipika cholimba cha alkali ndi mtundu wa zinthu zolimba za silicaalumina zomwe zimakhala ndi mphamvu yabwino yolimbana ndi kukokoloka kwa alkali mu uvuni wa simenti. Chipika cholimba cha alkali chili ndi mphamvu zambiri, kukhazikika bwino kwa voliyumu, kuthekera kokokoloka kwa alkali, ndi zina zotero. Chipika cholimba cha alkali chimagwiritsidwa ntchito pa chotenthetsera cha simenti ndi uvuni wowola.
Katundu wa Njerwa Zosagwira Alkali
- Utumiki wautali,
- Dongo lamoto loyera kwambiri,
- kukana kulowa mkati,
- Kukana bwino kwa alkali,
- Kukana kwapadera kwa alkali
- kukhazikika bwino kwa kutentha,
- Chithandizo chabwino cha mankhwala ophera tizilombo.
Njira Yopangira Njerwa Zosagwira Alkali
Njerwa zogonjetsedwa ndi alkali zimakhala pa kutentha kwambiri ndipo zimatha kuchitapo kanthu ndi alkali chitsulo okusayidi wopangidwa ndi madzi, zomwe zimapangitsa kuti glaze isinthe mawonekedwe ake, zomwe zimaphimba pamwamba pa njerwa, kuti zisalowerere ndi kuwonongeka kwa zinthu zosungunuka za alkali, zomwe zimapangitsa kuti alkali isagwe. Njerwa zogonjetsedwa ndi alkali zimatanthauza dongo losagonjetsedwa ndi alkali losagonjetsedwa ndi alkali ngati chinthu chachikulu chopangira, chomwe chimapangidwa ndi aluminiyamu mu uvuni wa simenti ndipo chimakhala ndi kukana bwino kwa alkali ndi kutentha kochepa.
Kugawa Njerwa Zosagonjetsedwa ndi Alkali
Njerwa zosagwirizana ndi alkali zitha kugawidwa m'mitundu inayi: njerwa zodziwika bwino zosagwirizana ndi alkali, njerwa zodziwika bwino zosagwirizana ndi alkali, njerwa zosagwirizana ndi alkali zosakanikirana ndi vault ndi njerwa zosagwirizana ndi alkali zosakanikirana ndi kutentha.
Njerwa yodziwika bwino yolimbana ndi alkali imagwiritsidwa ntchito makamaka mu uvuni wa simenti wotenthetsera ndi wowola katatu.
Njerwa yamoto yolimba kwambiri yolimbana ndi alkali imagwiritsidwa ntchito makamaka mu preheater ya simenti, ng'anjo yowola, ma duct atatu a mpweya, flue yokwera yoyimirira, ndi silinda ya mphepo.
Chotchinga cha mtundu wa Vault cholimba ndi alkali chimagwiritsidwa ntchito makamaka mu preheater ya simenti ndi uvuni wowonongeka katatu.
Chotchinga choteteza kutentha cha mtundu wa alkali cholimba chimakhala ndi kukana bwino dzimbiri kwa alkali komanso kutentha kochepa, komanso chimakhala ndi mphamvu zoteteza kutentha ngati zinthu zoteteza silika alumina.

Kugwiritsa Ntchito Njerwa Zosagwira Alkali
Njerwa zotsutsana ndi alkali zimakhala ndi mphamvu zambiri, zimakhala zolimba bwino, zimakhala ndi mphamvu yokoka ya alkali. Njerwa zotsutsana ndi alkali zimagwiritsidwa ntchito pa preheater ya simenti ndi ng'anjo yowola, njira yotulutsira mpweya, ndi zina zotero. Njerwa zotsutsana ndi alkali zimagwiritsidwanso ntchito mu dongosolo lotenthetsera la Kiln, ng'anjo yowola, njira yotulutsira mpweya.
Wopanga Njerwa Zosagwira Alkali kuchokera ku RS Refractory Factory
Fakitale yolimbana ndi alkali monga wopanga zida zolimbana ndi alkali ku China, ili ndi zabwino zambiri pamsika. Ngati mukufuna zida zolimbana ndi alkali, kapena muli ndi mafunso okhudza zida zolimbana ndi alkali zokhudzana ndi zizindikiro zakuthupi ndi zamankhwala, chonde titumizireni kwaulere, tidzakupatsani njerwa zapamwamba kwambiri zolimbana ndi alkali.
