High alumina ball,Inert alumina ceramic ball

扉、Inert alumina ceramic ball Inert alumina ceramic ball is widely used in many fields,such as petroleum,chemical engineering,fertilizer,smelting, medical treatment and environmental protection.Being the covering and supporting material and tower packing for catalyst in the reactor,ceramic ball has the feature of high temperature and plessure resistance,low water absorption,and stable chemical performance.It can not only resist the corrosion from the acid,alkali and other organic solvent,but also the temperature change in production process.The main role of ceramic ball is to increase the distributing spot of gas or liquid,also support and protect the activated catalyst with low strength. （扉）Main technical indices AL2O3 content 瘾镘哂 圊姻 feldstar feldstar mullite mullite mullite corundum corundum 20-25 25-45 45-70 70-90 ＞90 Heaping density（g/cm3） 1.4-2.0 water absorption（%） ＜3 ＜1 Acid resistance（%） ＞98 Alkaline resistance（%） ＞80 ＞82 ＞85 ＞90 ＞95 Temp. urgent change resistance∩ ＞250 ＞300 ＞500 ＞700 ＞800 Fire resistance∩ ＞1300 ＞1400 ＞1500 ＞1600 ＞1700 Compressive strength KN/pellet ヵ6 ＞0.40 ＞0.45 ＞0.6 ＞0.7 ＞0.8 ヵ8 ＞0.70 ＞0.8 ＞0.9 ＞1.0 ＞1.2 ヵ10 ＞0.90 ＞1.0 ＞1.2 ＞1.5 ＞1.8 ヵ13 ＞1.2 ＞1.3 ＞1.6 ＞1.8 ＞2.0 ヵ16 ＞1.5 ＞1.6 ＞1.8 ＞2.3 ＞2.6 ヵ20 ＞1.8 ＞2.0 ＞2.3 ＞2.8 ＞3.2 ヵ25 ＞2.5 ＞2.8 ＞3.2 ＞3.6 ＞4.0 ヵ30 ＞2.8 ＞3.0 ＞3.5 ＞4.0 ＞4.5 ヵ38 ＞4.0 ＞4.5 ＞5.0 ＞5.5 ＞6.0 ヵ50 ＞6.0 ＞6.2 ＞10.0 ＞10.5 ＞11.0 ヵ60 ＞8.0 ＞8.5 ＞11.0 ＞12.0 ＞14.0 ヵ70 ＞13.0 ＞11.0 ＞12.0 ＞14.0 ＞15.0 Remarks：Heaping density data is just for the reference, instead of examining basis. （欤）Main performance indices Item Unit Specification Composition Content Remarks specific gravity Kg/m3 2.2-2.4 Al2O3 30-85% 1、Al2O3 and SiO2 content ∶92% 2、Al2O3 and SiO2 two ingredients heights may request the fresh host according to the user. 3、Heaping density data is just for the reference, instead of examining basis.
