Kufotokozera kwa Njerwa ya Alumina Bubble
Njerwa ya moto ya alumina ndi mtundu watsopano wa zipangizo zotenthetsera kutentha kwambiri ndipo zimapangidwa ndi alumina ya mafakitale mu ng'anjo yamagetsi kudzera mu kusungunula ndi kupukutira. Njerwa ya alumina yolimba ngati kristalo ndi a-Al2O3 microcrystal ndipo thupi lalikulu ndi thovu la alumina lomwe lingapangidwe kukhala mitundu yonse ya zinthu zokhala ndi mawonekedwe osiyanasiyana kuti zipereke kutentha kwakukulu kwa 1800℃ ndi mphamvu yayikulu yamakina komanso kuchuluka kochepa.
Katundu wa Njerwa ya Alumina Bubble
- Kulemera kochepa,
- Kusunga mphamvu,
- Mtengo wotsika womanga,
- Kukana kutentha kwambiri,
- Kusintha kwa mzere wocheperako, kotenthetsera pang'ono,
- Kukana bwino kutentha ndi kugwedezeka.
Njira Yopangira Njerwa ya Alumina Bubble
Aluminium bubblle firebrick imagwiritsa ntchito alumina bubble ball ngati zipangizo zazikulu zopangira, ufa wapamwamba kwambiri wa ultrafine ngati wothandizira wowonjezera ndi chinthu chachilengedwe ngati wothandizira womangirira kudzera mu umba ndi kuumitsa, kenako imawotchedwa mu uvuni wa shuttle wotentha kwambiri.
Ubwino wa Alumina Bubble Brick
Njerwa ya aluminiyamu ya bubblle ili ndi mawonekedwe oteteza kutentha komanso kutentha kochepa, zomwe zingayambitse kutentha kwambiri, kuchepetsa kutaya kwa kutentha ndikuwonjezera mphamvu ya kutentha. Kugwiritsa ntchito njerwa ya aluminiyamu ya bubblle yotsutsa kumatha kusunga mphamvu mpaka 30%. Ndipo kutentha kwa alumina bubble block ndi kokwera mpaka 1750 ℃. Kukhazikika kwa kutentha ndikwabwino ndipo kutentha kobwerezabwereza kosintha kwa mzere kumakhala kochepa, ndipo aluminium bubble block ingapangitse kuti ikhale nthawi yayitali yogwira ntchito.

Kugwiritsa Ntchito Njerwa ya Alumina Bubble
Njerwa ya alumina ndi chinthu chofunikira kwambiri choletsa kutentha kwambiri komanso zofunikira zapadera pa ng'anjo ndi uvuni, zomwe zimagwiritsidwa ntchito kwambiri ngati njerwa zotetezera kutentha kwa ng'anjo ndi uvuni, komanso njerwa ya aluminiyamu ingagwiritsidwe ntchito popanga zinthu zoyera kwambiri zamagetsi monga matailosi a ceramic mu ma turbine a gasi ndi zinthu zosungiramo zinthu mu ma reactor.
Wopanga Njerwa za Alumina Bubble kuchokera ku RS Refractory Factory
Fakitale yopangira njerwa za alumina ku China, monga katswiri wopanga njerwa za alumina ku China, ili ndi zabwino zambiri pamsika. Ngati mukufuna njerwa za aluminiyamu, kapena muli ndi mafunso okhudza njerwa za aluminiyamu zokhudzana ndi zizindikiro zakuthupi ndi zamankhwala, chonde titumizireni kwaulere, tidzakupatsani njerwa zapamwamba kwambiri zopangira njerwa za aluminiyamu.
