Aluminum oxide yumbu aikin yi

1--Taurin kai

Taurin Rockwell na alumina yumbu shine HRA80-90, na biyu kawai zuwa lu'u-lu'u a cikin taurin, fiye da ƙarfe mai jure lalacewa da juriya bakin ƙarfe.

2--Kyakkyawan Juriya

Juriya na yumbu alumina yayi daidai da sau 266 na ƙarfe na manganese da sau 171.5 na babban simintin ƙarfe na chromium.A ƙarƙashin yanayin aiki iri ɗaya, zai iya tsawaita rayuwar sabis na kayan aiki aƙalla sau goma.

3--Haske Nauyi

Girman yumburan alumina shine 3.7 ~ 3.95g / cm °, wanda shine rabin na baƙin ƙarfe da ƙarfe, kuma yana iya rage nauyin kayan aiki sosai.

4-- Faɗin Aikace-aikacen

Alumina yumbu ana amfani da ko'ina a cikin inji, fiber optics, yankan kayan aikin, likita, abinci, sunadarai, sararin samaniya da sauran filayen.

Abubuwan da ake amfani da su na alumina ceramics:

1--Alumina yumbura suna da kyawawan abubuwan rufewa.Babban hasara mai girma yana da ƙananan ƙananan, kuma babban juzu'i yana da kyau.

2--Alumina yumbura suna da juriya na zafi, ƙananan ƙima na haɓakar thermal, ƙarfin injina mai ƙarfi da haɓakar thermal mai kyau.

3--Alumina yumbu suna da juriya na sinadarai da juriya na narkakkar.

4--Alumina tukwane ba flammable, ba sauki ga tsatsa da kuma karfi da kuma ba sauki lalacewa, tare da sauran Organic kayan da karfe kayan ba za a iya kwatanta da kyau kwarai inganci.

5--Alumina yumbura mafi girman juriya, taurin da corundum iri ɗaya, na iya kaiwa ga taurin Mohs 9, juriyar sa na iya dacewa da manyan allurai masu ƙarfi.
