Polycrystalline Al2O3 alumina yumbu da aka keɓance babban juriya na zazzabi

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 jurewa da juriya na 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.
