Kufotokozera kwa Njerwa za Alumina
Njerwa yamoto ya Alumina ndi mtundu watsopano wa zida zotenthetsera zotentha kwambiri komanso zopangidwa ndi aluminiyamu yamafakitale mung'anjo yamagetsi kudzera pakusungunula ndi kuwomba. aluminium kuwira refractory njerwa crystal mawonekedwe ndi-Al2O3 microcrystal ndi thupi lalikulu ndi aluminiyamu kuwira amene akhoza kukhala mitundu yonse ya zinthu akalumikidzidwa zosiyanasiyana zotumikira kutentha kwambiri 1800 ℃ ndi mkulu makina mphamvu ndi otsika chochuluka kachulukidwe.
Katundu wa Alumina Bubble Brick
- Kulemera pang'ono,
- Kupulumutsa mphamvu,
- Kutsika mtengo womanga,
- Kukana kutentha kwakukulu,
- Kusintha kwa mzere wocheperako,
- Kukana kwamphamvu kwamafuta.
Njira Yopangira Njerwa ya Alumina Bubble
Aluminiyamu bubblle firebrick kutengera aluminiyamu kuwira mpira monga waukulu zipangizo, mkulu ntchito ultrafine ufa monga annexing wothandizila ndi organic monga wothandizila pomanga ndi kuyanika, ndiyeno amawotchedwa mu mkulu kutentha shuttle ng'anjo.
Ubwino wa Alumina Bubble Brick
Njerwa yamoto ya aluminium bubblle imakhala ndi mawonekedwe a kutentha kwapakati komanso kutsika kwamafuta, zomwe zingayambitse kutentha kwakukulu, kuchepetsa kuwonongeka kwa kutentha ndikuwongolera kutentha. Kugwiritsira ntchito njerwa ya aluminium bubblle refractory kumatha kupulumutsa mphamvu mpaka 30%. ndi kutentha kwa ntchito ya alumina bubble block 'ndipamwamba kwambiri mpaka 1750 ℃. kukhazikika kwamafuta ndikwabwino komanso kusinthika kwa mzere wowongoka ndikotsika, chipika cha aluminium bubble chingabweretse moyo wautali wautumiki.

Kugwiritsa ntchito njerwa ya Alumina Bubble
Alumina kuwira njerwa ndi mtundu wa zinthu zofunika kwambiri refractory kukana kutentha mkulu ndi zofuna zapadera za maudindo ng'anjo ndi ng'anjo, amene makamaka ntchito ngati insulating njerwa kutchinjiriza wosanjikiza ng'anjo ndi ng'anjo, komanso zotayidwa kuwira njerwa angagwiritsidwe ntchito utumiki. linings popanga quartz yoyera kwambiri pamakampani opanga zamagetsi monga zomangira matailosi a ceramic mu ma turbines a gasi ndi zomangira zosunga zobwezeretsera muma reactor.
Alumina Bubble Brick Manufacturer kuchokera ku RS Refractory Factory
RS refractory fakitale monga katswiri alumina kuwira njerwa wopanga ku China, ndi ubwino zambiri mpikisano mu msika. ngati mukufuna njerwa za aluminiyamu kuwira njerwa, kapena muli ndi mafunso pa aluminiyamu kuwira firebrick zokhudza zizindikiro thupi ndi mankhwala, chonde tilankhuleni kwaulere, tidzakupatsani apamwamba aluminiyamu kuwira refractory njerwa.
