High quality corundum bricksyog cov khoom nrog Al2O3 cov ntsiab lus tshaj 90%. Muaj semi-bonded corundum cib, ncaj-bonded corundum cib thiab ntom corundum cib. Semi-bonded los yog ncaj qha-bonded cib yog tsim nrog fused corundum (los yog sintered corundum) thiab calcined alumina ua raw cov ntaub ntawv, Aluminium sulphate los yog recycled pulp pov tseg yog siv los ua tus neeg sawv cev. Cov cib yog nias nyob rau hauv siab siab thiab raug rho tawm haujlwm nyob rau hauv qhov kub ntawm 1750-1800 degree. Nthuav corundum cib yog tsim nrog lub teeb ci alumina hmoov, dextrin yog siv los ua tus neeg sawv cev. Artificial granulation technology yog siv kom tau txais cov khoom siv raw, ces nias rau hauv siab. Cov tuab corundum cib kuj tseem sintered nyob rau hauv qhov kub ntawm 1750-1800 degree. Nrog siab Al2O3 cov ntsiab lus, tsis tshua pom porosity, siab zog, zoo heev corrosion kuj thiab yaig tsis kam, ntom corundum cib feem ntau yog siv ua hauj lwm hauv ob sab phlu ntawm Synthetic ammonia rauv.
Cov ntaub ntawv tseem ceeb:
1.Brown fused alumina / xim av fused corundum: xim av fused alumina yog tsim los ntawm siab alumina bauxite thiab carbon, fused nyob rau hauv hluav taws xob rauv kub kub 2000 degree.
2.White fused alumina / Dawb fused corundum: nws yog tsim los ntawm calcined alumina fused nyob rau hauv hluav taws xob rauv kub.
3.High alumina corundum yog tsim los ntawm super zoo siab alumina bauxite, tshwj xeeb smelting rauv yog siv nrog 2500℃kub hluav taws xob rauv.
4.Zirconia corundum: nws yog tsim los ntawm zirconia thiab alumina hmoov nyob rau hauv micro particle qhov ntau thiab tsawg, cov khoom yog muaj tom qab fused nyob rau hauv ultra high kub hluav taws xob rauv.
5.Single crystalline corundum: tseem hu ua 32A fused alumina ua cov khoom sib tsoo.
6.Micro crystalline corundum: ua los ntawm high alumina bauxite, nws muaj tom qab fused nyob rau hauv ultra kub nyob rau hauv lub cub tawg, thiab ces muaj kev kub ceev txo cov txheej txheem.
Kev siv cov khoom zoo corundum cib thiab cov ntaub ntawv corundum
1. Cov khoom siv sib tsoo: nws yog siv los ua cov khoom sib tsoo lossis cov khoom siv abrasive rau hlau, xws li steel, casting hlau, tawv bronze thiab lwm yam.. Brown fused alumina kuj tseem siv tau los ua raw khoom ntawm corundum bricks thiab castable.
2.Top qib polishing khoom
3.Pwm xuab zeb ntawm precision steel casting, blasting xuab zeb, gunning mix, tshuaj catalyst, tshwj xeeb ceramic thiab lwm yam.
4.Dry sib tsoo cov ntaub ntawv, engineering kom yooj yim - hlawv & yooj yim deforming workpieces
5.Qhov ua haujlwm hauv ob sab phlu & rooj tog rau ntau yam kub kub kilns, furnaces hauv petrochemical kev lag luam, chiv industries, metallurgical industries thiab lwm yam.
