Aluminium oxide npas yeej ib txwm yog qhov nruab nrab ntawm lub ntiajteb txawj nqus ntawm peb lub Hoobkas tsim, nrog rau qhov ntau thiab tsawg ntawm 0.1-90mm thiab cov ntsiab lus ntawm 92 txog 99%.
Peb cov neeg siv khoom Indonesian nyuam qhuav yuav 50 hli alumina pob rau kev sib tsoo cov ntaub ntawv raw ntawm lub Hoobkas ceramic. Alumina npas feem ntau yog siv los ua kev sib tsoo xov xwm vim lawv cov khoom zoo heev xws li siab hardness, zoo hnav tsis kam thiab tsis tshua muaj thermal expansion.Aluminium oxide npas tau dav siv los ua kev sib tsoo xov xwm hauv ntau yam lag luam xws li ceramics, tshuaj, xim thiab ntxhia.
Alumina pob muaj ntau qhov zoo dua lwm cov xov xwm sib tsoo. Lawv muaj cov yam ntxwv hauv qab no:
1. High hardness:
Aluminium oxide pob yog qhov nyuaj heev thiab zoo tagnrho rau kev sib tsoo cov ntaub ntawv nyuaj xws li cov ntxhia, hlau thiab ceramics.
2. Zoo abrasion tsis kam:
Aluminium oxide npas yog hnav tiv taus thiab tuaj yeem tiv taus kev cuam tshuam thiab kev sib txhuam. Qhov no ua rau lawv haum rau kev sib tsoo ntev thiab pab txo qis kev lag luam.
3. Tsawg thermal expansion:
Alumina npas muaj cov coefficient qis ntawm thermal expansion, uas txhais tau tias lawv tsis nthuav lossis cog lus ntau nrog kev hloov pauv kub. Qhov thermal stability no ua kom muaj kev sib tsoo zoo ib yam dhau ntawm qhov kub thiab txias.
4. Nqi-zoo:
Tus nqi-zoo ntawm alumina npas piv rau lwm cov xov xwm sib tsoo ua rau lawv thawj qhov kev xaiv rau kev lag luam tab tom nrhiav kev sib tsoo kev lag luam.
Yog tias koj txaus siab rau cov khoom no, thov nyem rau hauv qab no kom paub ntau ntxiv thiab tiv tauj peb.
