Brown corundum refractoriness taw qhia

Ua ntej, xim av corundum refractoriness qhia
Brown corundum yog lub siab hardness, siab ceev, siab melting point khoom nrog zoo heev kub kuj. Nws cov khoom tseem ceeb yog alumina, yog li nws muaj kev tiv thaiv corrosion zoo thiab hnav tsis kam.
Raws li kev sim cov ntaub ntawv, qhov hluav taws kub tsis kam ntawm cov xim av corundum feem ntau yog li ntawm 1800-1900 degree C, uas tuaj yeem siv rau hauv qhov chaw hnyav xws li cov rooj tog zaum kub. Nyob rau tib lub sijhawm, xim av corundum kuj muaj cov coefficient me me ntawm thermal expansion, zoo thermal shock stability thiab lwm yam khoom zoo heev.

Vim nws zoo heev kub tsis kam, xim av corundum yog dav siv nyob rau hauv ib tug ntau yam ntawm demanding industrial daim ntaub ntawv. Nov yog qee qhov kev thov hauv cheeb tsam:
1. Cov khoom siv refractory: Cov xim av corundum tuaj yeem siv los tsim cov cib refractory, rauv hauv ob sab phlu thiab lwm yam khoom siv kub-resistant.
2. Abrasive cov ntaub ntawv: Brown corundum yuav siv tau los ua abrades, uas yog siv nyob rau hauv hlau ua, hluav taws xob tivthaiv manufacturing thiab lwm yam lag luam.
3. Electronic ceramics: Brown corundum tuaj yeem siv los tsim hluav taws xob ceramics, dav siv hauv cov khoom siv hluav taws xob ntim, xov xwm thiab lwm yam.
4. Lwm qhov chaw: Brown corundum kuj tuaj yeem siv los tsim cov cuab yeej thermal, khoom siv hauv tsheb, fiber ntau ceramics thiab lwm yam khoom.
Nyob rau hauv luv luv, xim av corundum muaj zoo heev kub tsis kam thiab lwm yam khoom zoo heev, thiab yog dav siv nyob rau hauv ntau yam kev lag luam teb.
