Njerwa za Corundum mullite

Njerwa za Corundum mullite

Ubwino wazogulitsa: kutentha kwambiri, kukana kutentha kwa dzimbiri, kukaniza makutidwe ndi okosijeni, kukhazikika kwamatenthedwe, komanso kusintha kwakanthawi kochepa.

Mankhwala ntchito: Makamaka ntchito mu petrochemical makampani, lalikulu ndi sing’anga-kakulidwe kupanga ammonia gasifier ndi maginito zinthu gasi ng’anjo zipangizo, mkulu-kutentha mafakitale uvuni akuthandiza maofesi zipangizo, etc.

Mafotokozedwe Akatundu

Njerwa za Corundum ndi mullite zimapangidwa ndi chiyero choyera kwambiri cha corundum ndi mullite ngati zopangira, zopangidwa ndi kuthamanga kwambiri ndikuwotcha kutentha kwambiri. Mankhwala ali ndi makhalidwe a kutentha kukana, dzimbiri kukana, kukana makutidwe ndi okosijeni, wabwino matenthedwe bata, ndi otsika mlingo liniya kusintha.

Kufotokozera kwa njerwa za corundum mullite:

1. Zida zolemera zimakhala ndi mgwirizano wabwino, mphamvu yayikulu yotsutsana, kukana mitundu ingapo yowononga, kukhazikika kwabwino kwamatenthedwe, kutentha kwambiri kwamatenthedwe, ndi kuvala kukana.

2. Zida zopepuka zimakhala ndi mawonekedwe amkati ofanana, mphamvu yayikulu yothina, dzimbiri, kukana kutentha, kukaniza makutidwe ndi okosijeni, kutentha kwambiri kwa magwiridwe antchito komanso kutsika kwamatenthedwe otsika.

Zizindikiro zakuthupi ndi zamankhwala
