Njerwa Zapamwamba za Alumina Refractory za Ng'anjo ya Industrial

1. Njerwa zapamwamba za alumina ndi njerwa zotsutsa zomwe zimapangidwa makamaka kuchokera ku alumina (Al2O3) ndi zipangizo zina, zopangidwira ntchito zotentha kwambiri monga ng'anjo, ng'anjo, ndi ma reactors.
2.Processing: bauxite imagwiritsidwa ntchito ngati zopangira zazikulu, clinker imasankhidwa ndi grading ndi sieved kuchotsa chitsulo, ndipo imakonzedwa ndi kutentha kwakukulu.
3. Kupanga Zinthu: Zimapangidwa mwa kusakaniza zinthu zopangira (bauxite kapena miyala ina ya aluminiyamu yapamwamba), kuziumba kukhala njerwa, ndi kuziwotcha pa kutentha kwakukulu. Kupanga kungaphatikizepo zowonjezera ndi zomangira zosiyanasiyana kuti mukwaniritse zomwe mukufuna.
4. Njerwa zapamwamba za alumina zimasankhidwa kuti zikhale zolimba komanso zogwira ntchito m'madera ovuta kwambiri, zomwe zimapangitsa kuti zikhale zofunikira kwambiri m'mafakitale ambiri otentha kwambiri.

Zoyambitsa Njerwa Zapamwamba za Alumina2

1. High Refractoriness: Amatha kupirira kutentha kwambiri, kuwapanga kukhala oyenera kugwiritsidwa ntchito m'ng'anjo ndi malo ena otentha kwambiri.

2. Kukhazikika Kwabwino Kwambiri Kutentha: Njerwazi zimasunga umphumphu wawo komanso makina amakina ngakhale pakusintha kutentha kwachangu, kuchepetsa chiopsezo cha kuwonongeka kwa kutentha kwa kutentha.

3. Katundu Wabwino Wotsekera: Ngakhale kuti sizothandiza ngati zida zapadera zotsekera, njerwa zapamwamba za aluminiyamu zimapereka zotsekera potengera kutentha, zomwe zimathandiza kusunga mphamvu pamafakitale.

4. Kukana Kuwonongeka ndi Kuwonongeka: Zimagonjetsedwa ndi kuwonongeka kwa mankhwala ndi zovala zamakina, zomwe zimatalikitsa moyo wawo m'mikhalidwe yovuta yogwirira ntchito.

5. Low Thermal Conductivity: Katunduyu amathandizira kuchepetsa kutayika kwa kutentha ndikusunga mawonekedwe a kutentha mkati mwa chitsulo chotchinga.

Ponseponse, njerwa zazitali za alumina zimakhala zamtengo wapatali chifukwa cha kulimba, kudalirika, komanso kutha kupirira zovuta m'njira zosiyanasiyana zamafakitale.

Kugwiritsa ntchito

Njerwa zapamwamba za alumina zimagwiritsidwa ntchito m'mafakitale monga zitsulo, simenti, magalasi, ndi zitsulo zadothi kuti athe kupirira kutentha kwambiri komanso mikhalidwe yovuta. ng'anjo yoyaka moto ya masonry, chitofu choyaka moto, ng'anjo yamagetsi yamagetsi pamwamba ndi ladle yokhazikika.
