magnesite alumina njerwa ndi mtundu wa mankhwala alkaline refractory ndi perriclase monga gawo lalikulu magnesia alumina spinel clinker monga zinthu zofunika .magnesia alumina firebrick ali ndi makhalidwe monga kutentha kugwedezeka kwabwino, mphamvu zabwino ndi kukhazikika kwa voliyumu kutentha kwakukulu. Njerwa ya magnesia alumina refractory ili ndi mawonekedwe abwino kukana kugwedezeka kwamafuta, kukana kwambiri pansi pa katundu, kutentha kofewetsa katundu pamwamba pa 1580 ℃, kukana kukokoloka kwa magalasi ndikwabwino. Zomwe zitha kugwiritsidwa ntchito kwambiri pama projekiti a simenti apanyumba ndi kunja.
Katundu wa Magnesia Alumina Njerwa
- Chapadera kukana mankhwala kuukira
- Kukana kwambiri kwa thermal-shock,
- Refractoriness kwambiri,
- Kukana bwino kwa abrasion,
- Kuchita bwino kwambiri pansi pa katundu wotentha komanso wamakina.
Njira Yopangira Magnesia Alumina Njerwa
Magnesia alumina firebrick makamaka amagwiritsa ntchito magnesia alumina spinel ngati masanjidwewo. Kuti apititse patsogolo kukana kwa kutentha kwa njerwa ya magnesia, ufa wabwino wa alumina kapena bauxite clinker umayambitsidwa mu batching kuti apange matrix a alumina spinel matrix. Njerwa yamoto ya Magnesia alumina ili ndi mawonekedwe abwino kukana kugwedezeka kwamafuta, kukana kwambiri ponyamula katundu, kutentha kwapang'onopang'ono pamwamba pa 1580 ℃, kukana kukokoloka kwa magalasi.
Kupanga kwa Magnesia Alumina Njerwa
Magnesium aluminiyamu moto njerwa ndi mtundu wa spinel zofunika refractory lili pafupifupi 85% MgO ndi 5% ~ 10% Al2O3. Gawo la crystalline la magnesium alumina firebrick limapangidwa makamaka ndi miyala yayikulu ya magnesia ndi magnesia alumina spinel. The spinel aggregates pambuyo crystallization kupanga kristalo maukonde, zomwe zimapangitsa kuti zomangamanga compact.Chifukwa popanga, musagwiritse ntchito aggregate ya bulky granule, lonse njerwa thupi kapangidwe ndi ngakhale, stoma disperses.
Kupaka kwa Magnesia Alumina Njerwa
1.Pa pallets matabwa ndi pulasitiki chivundikiro: matabwa mphasa kukula: 930 * 930 kapena 1000 * 1000mm,
2.Kulemera kwa phale lililonse: matani 1.5-2.0,

Kugwiritsa ntchito njerwa za Magnesia Alumina
Magnesia alumina chipika ndi ntchito kwambiri, mankhwala athu akhala akugwiritsidwa ntchito m'nyumba ndi kunja ntchito simenti. Komanso midadada ya magnesia alumina ingagwiritsidwe ntchito posinthira zone ya simenti yozungulira, zopangiranso matanki agalasi ndi ma kilni a laimu.
Magnesia Alumina Bricks Manufacturer kuchokera ku RS Refractory Factory
RS refractory fakitale ndi katswiri wopanga njerwa za aluminiyamu magnesite omwe adakhazikitsidwa koyambirira kwa 90s zaka makumi awiri. Fakitale ya RS refractory yakhazikika mu njerwa za alumina za maginito kwa zaka zopitilira 20. ngati muli ndi zofunikila za magnesite alumina block, kapena muli ndi mafunso pa maginito alumina firebrick okhudza zizindikiro zakuthupi ndi zamankhwala, chonde titumizireni kwaulere. ndi Rs refractory fakitale monga katswiri wopanga njerwa za maginito alumina refractory ku China, ali ndi mwayi wopikisana nawo motere:
- Mtengo Wopikisana: Pangani zinthu kukhala zopikisana pamsika wanu,
- Zochitika Zambiri: Pewani ming'alu ndi kupotoza njerwa,
- Mitundu Yosiyanasiyana: Sungani ndalama za nkhungu kwa inu,
- Kuwongolera Kwabwino Kwambiri: Kukwaniritsa zofunika zamakasitomala,
- Zogulitsa zazikulu: Kutumiza mwachangu,
- Professional Packing: Pewani kuwonongeka ndikuteteza katunduyo pamayendedwe.
