Qhov zoo thiab qhov tsis zoo ntawm corundum thiab nws daim ntawv thov teb
Corundum yog cov khoom siv tseem ceeb uas muaj ntau yam tshwj xeeb thiab qhov zoo, tab sis kuj muaj qee qhov tsis zoo. Kab lus no yuav tham txog qhov zoo thiab qhov tsis zoo ntawm corundum thiab qhia nws daim ntawv thov hauv ntau daim ntawv thov.
I. Qhov zoo
High hardness: Corundum yog ib qho ntawm cov paub txog cov ntxhia nyuaj, thiab nws qhov hardness yog thib ob tsuas yog pob zeb diamond. Yog li ntawd, corundum muaj kev hnav zoo heev, tuaj yeem tiv taus kev siv zog thiab khawb, thiab tuav lub sijhawm ntev.
Kev ruaj ntseg kub siab: Corundum tuaj yeem nyob ruaj khov hauv qhov kub thiab txias thiab tuaj yeem tiv taus kub thermal shock. Qhov no ua rau corundum dav siv nyob rau hauv high-temperature processes thiab high-temperature khoom, xws li roj refining, ceramics thiab electronics industries.
Kev ruaj ntseg tshuaj zoo: corundum muaj kev tiv thaiv corrosion zoo nyob rau hauv kev tawm tsam ntawm cov tshuaj xws li kua qaub thiab alkali. Qhov no ua rau corundum yog ib qho zoo tshaj plaws corrosion resistant khoom, uas yuav siv tau nyob rau hauv kev lag luam tshuaj, metallurgical kev lag luam thiab lwm yam teb.
Kev rwb thaiv tsev siab: Corundum yog ib qho zoo heev insulator, uas tuaj yeem thaiv qhov ntws ntawm tam sim no. Yog li ntawd, corundum yog dav siv nyob rau hauv electronics, hluav taws xob thiab kev sib txuas lus teb, rau kev tsim cov insulators, capacitors thiab circuit boards.
Nyem qhov no mus saib daim duab nyob rau hauv lub qhov rais tshiab
Ii. Qhov tsis zoo
Nqi: Corundum yog kim los tsim vim nws txoj kev mining thiab kev ua haujlwm. Qhov no ua rau tus nqi ntawm corundum siab, txwv nws daim ntawv thov dav hauv qee thaj chaw.
Brittleness: Txawm hais tias corundum muaj siab hardness, nws kuj yog nkig heev. Thaum muaj kev cuam tshuam zoo los yog siv tsis raug, corundum tuaj yeem tawg lossis deform, txo nws txoj kev pab cuam lub neej thiab kev ntseeg siab.
3. Daim ntawv thov teb
Abrasives thiab sib tsoo cov cuab yeej: Vim nws qhov siab hardness thiab hnav tsis kam, corundum yog dav siv los ua cov cuab yeej sib tsoo, xws li ntawv xuab zeb, sib tsoo lub log thiab cov cuab yeej txiav. Nws ua lub luag haujlwm tseem ceeb hauv kev ua hlau, kev tsim iav thiab lwm yam lag luam.
Cov ntaub ntawv ceramic: Corundum muaj cov thermal stability zoo thiab corrosion kuj, thiab yog dav siv nyob rau hauv kev tsim cov khoom siv ceramic, xws li cov cuab yeej txiav, cov kav dej ceramic thiab cov khoom siv ceramic refractory.
Kev kho qhov muag: Corundum muaj qhov pom tseeb zoo thiab cov khoom siv kho qhov muag, thiab tau siv dav hauv cov cuab yeej kho qhov muag, cov duab thaij duab thiab cov khoom siv laser.
Kev lag luam hluav taws xob: Raws li cov khoom siv hluav taws xob, corundum tau siv dav hauv kev tsim cov khoom siv hluav taws xob, xws li capacitors, insulators thiab semiconductor li.
Hauv cov ntsiab lus, raws li cov khoom siv tseem ceeb, corundum muaj qhov zoo ntawm qhov siab hardness, kub stability, tshuaj stability thiab zoo rwb thaiv tsev. Txawm hais tias nws tus nqi siab thiab yooj yim rau kev tawg, nws daim ntawv thov dav hauv thaj chaw ntawm abrasives, ceramics, optics thiab electronics tau ua corundum ua lub luag haujlwm tseem ceeb thiab pab txhawb rau kev tsim kho ntawm ntau yam lag luam.
