Corundum Bricks-Hengli

Njerwa za Hengli Corundum zimapangidwa kuchokera ku alumina yoyera kwambiri ya tabular, aluminiyamu wosakanikirana, wotenthedwa mumoto wotentha kwambiri. Njerwazo zimakhala ndi mawonekedwe a kachulukidwe kwambiri, kuyera kwambiri, kutsika kwa porosity, komanso kukana kugwedezeka kwamafuta.
Njerwa za Hengli Corundum zimatha kupirira kuwonongeka kwa dzimbiri mumlengalenga wotulutsa okosijeni komanso kuchepetsa kwambiri mlengalenga. Itha kupiriranso kutentha kwa hydrogen.
Njerwa ya Hengli Corundum imapezeka mu makulidwe a njerwa (yowongoka, mabwalo ndi ma wedge) komanso mbale ndi mawonekedwe ake.

Mawonekedwe

Njerwa za Corundum, zomwe zimadziwikanso kuti alumina njerwa, ndizinthu zopangira aluminiyamu kwambiri zomwe zili ndi zinthu zingapo zofunika:

1. **Kuyera Kwambiri: **Amapangidwa ndi aluminiyamu wopitilira 90% (Al2O3), kuwonetsetsa kuti zinthu zabwino kwambiri zokanira.

2. **Kukana Kutentha Kwambiri: **Amatha kupirira kutentha mpaka 1900 ° C, kuwapanga kukhala oyenera malo omwe amafunikira kwambiri kutentha kwambiri.

3. **Mphamvu zamakina: **Njerwa za Corundum zimakhala ndi mphamvu zopondereza kwambiri komanso kukana kuvala bwino, zomwe zimawathandiza kuthana ndi katundu wolemetsa komanso zovuta.

4. **Kulimbana ndi Corrosion: **Amapewa dzimbiri kuchokera ku slags, asidi, alkalis, ndi mankhwala ena, kukulitsa moyo wawo m'malo ovuta.

5. **Kuchepa Kwambiri: **Kutsika kwa porosity kumathandizira kupewa kulowetsedwa kwa zinthu zosungunuka ndi mpweya, kumapangitsa kukhazikika komanso kutsekemera kwamafuta.

6. **Kukhazikika kwa Thermal: **Amawonetsa kukhazikika kwamafuta komanso kukana kugwedezeka kwamafuta, zomwe ndizofunikira kwambiri pamachitidwe okhudzana ndi kusintha kwachangu kutentha.

7. **Kukhazikika kwa Dimensional: **Zomwe zili pamwamba pa alumina zimatsimikizira kuti njerwa zimasunga mawonekedwe awo ndi kuchuluka kwake pa kutentha kwakukulu, kuteteza kulephera kwa mapangidwe.

Izi zimapangitsa kuti njerwa za corundum zikhale zoyenera kuti zigwiritsidwe ntchito pamitundu yosiyanasiyana yotentha kwambiri, kuphatikiza ng'anjo zophulika, masitovu otentha, ma ladle achitsulo, ndi ng'anjo zina zamafakitale.

Kugwiritsa Ntchito

Amagwiritsidwa ntchito kwambiri m'mafakitale monga feteleza, ma electro ceramics, petrochemical, iron, foundry, aloyi zitsulo, refractories, etc. Ntchito yofananira monga kusintha kwachiwiri ndi kuyika kwa jenereta ya gasi, chithandizo cha bedi chothandizira, ng'anjo yopangira ng'anjo, kutenthetsa ng'anjo yamoto, ndi zina zotero.
