Alkali kusamva chipika ndi mtundu wa otsika njerwa alumina, okhutira Al2O3 ndi 30-25%, mfundo yaikulu ya alkali kusamva midadada ndi otsika alumina refractory dongo, alkali kusamva moto chipika ndi mtundu wa silicaalumina mndandanda refractory mankhwala ndi zabwino kukokoloka kukana alkali. ntchito mu makina opangira simenti. alkali resistant refractory block ili ndi mphamvu zambiri, kukhazikika kwa voliyumu yabwino, mphamvu yakukokoloka kwa alkali, etc.
Katundu wa Njerwa Zosagwirizana ndi Alkali
- Utumiki wautali,
- Dongo lamoto loyera kwambiri,
- kukana kulowa,
- Kukana kwa alkali wabwino,
- Kukana kwambiri kwa alkali
- kukhazikika kwamphamvu kwamafuta,
- Thandizo lodziwika bwino la mankhwala.
Njira Yopangira Njerwa Zosagwirizana ndi Alkali
Njerwa zamchere kugonjetsedwa ndi kutentha akanakhoza kuchita ndi zamchere zitsulo okusayidi kwaiye mkulu mamasukidwe akayendedwe a madzi gawo, kupanga wosanjikiza glaze anasintha mawonekedwe wosanjikiza, kuphimba pamwamba pa njerwa chipika pamwamba pores, kuteteza kulowerera ndi kukokoloka kwa alkali. zitsulo zosungunuka, ndi cholinga cha kukokoloka kwa alkali. alkali kusamva chipika amatanthauza otsika alkali kugonjetsedwa njerwa refractory dongo monga chuma chachikulu, amene amapangidwa ndi zotayidwa mu uvuni simenti dongosolo ndipo ali wabwino kukana dzimbiri alkali ndi otsika matenthedwe madutsidwe.
Gulu la Njerwa Zosagwirizana ndi Alkali
Njerwa zosagwirizana ndi alkali zitha kugawidwa m'mitundu inayi: njerwa zosagwirizana ndi alkali, njerwa zamphamvu za alkali zosagwira moto, zotchingira zamtundu wa alkali zosagwira chipika ndi chipika chotchinjiriza chamtundu wa alkali.
Njerwa zosagwirizana ndi alkali zimagwiritsidwa ntchito kwambiri mu uvuni wotenthetsera simenti ndi ng'anjo yowola katatu.
Zida zoyaka moto zamphamvu kwambiri za alkali zimagwiritsidwa ntchito makamaka mu ng'anjo yowotchera simenti, ng'anjo yowonongeka, ma ducts atatu a mpweya, chitoliro chokwera chokwera, silinda yamkuntho.
Vault mtundu wa alkali resistant block umagwiritsidwa ntchito makamaka mu chotenthetsera cha simenti ndi ng'anjo yowola katatu.
Matenthedwe otchinjiriza amtundu wa alkali resistant block ali ndi kukana kwa dzimbiri kwa alkali komanso kutsika kwamafuta otsika, amakhala ndi magwiridwe antchito a silika alumina refractory.

Kugwiritsa Ntchito Njerwa Zosagwirizana ndi Alkali
Njerwa zosagwirizana ndi alkali zimakhala ndi mphamvu zambiri, kukhazikika kwa voliyumu yabwino, kukokoloka kwa alkali. Njerwa zosagwirizana ndi alkali zimagwiranso ntchito pa ng'anjo yowotchera simenti ndi ng'anjo yowola, njira yolumikizira mpweya, etc. njerwa zosagwira moto za alkali zomwe zimagwiritsidwanso ntchito mu Kiln preheating system, ng'anjo yowola, njira yapamtunda wapamwamba.
Wopanga Njerwa Za Alkali Kuchokera ku RS Refractory Factory
RS refractory fakitale monga katswiri alkali kugonjetsedwa refractory chipika wopanga ku China, ndi zabwino zambiri mpikisano mu msika. ngati mukufuna chipika cha alkali resistant block, kapena muli ndi mafunso okhudzana ndi zozimitsa moto zosagwirizana ndi alkali zokhudzana ndi zizindikiro zakuthupi ndi zamankhwala, chonde titumizireni kwaulere, tidzakupatsirani njerwa zapamwamba kwambiri zosagwirizana ndi alkali.
