Alumina Ball

Author:Jinlin corundumTo update: 2016-09-19

With the development of the times, we are increasingly focused on health issues and other aspects, such as clean and unclean drinking water, home decoration, etc. just finished pungent odor, it today, I’ll stay here and to introduce a home essential artifact – alumina ball. It alumina ball over for us to resolve our troubles, let you easily through life.

I.Alumina balls overview:

Alumina ball is a porous, high dispersion of solid materials, the appearance of 0.68-0.89g / cm3 of white spherical, uniform size, a large specific surface area, the porous surface with catalytic properties required .

Alumina ball production process: in AL2O3 as raw material, the use of ultra-fine powders into a ball machine or isostatic molding and high temperature roasting.

Alumina balls often sold specifications: 1-3mm, 3-5mm, 4-6mm, 5-8mm, 8-16mm, etc. We can also carry out production and processing according to customer requirements.

II.Alumina ball features:

1.Alumina ball of uniform size, smooth surface, high mechanical strength, moisture absorption, no swelling maintain the status quo does not crack after absorbing water.

2.Alumina ball having a non-toxic, odorless, insoluble in water features.

3.There must be a huge surface area and the large porosity, loose adsorbent structure must be highly porous and huge exposed surface material.

4.For different gas to selective adsorption. Purpose industrial applications adsorbent is certain to selectively adsorbed gas component, so as to achieve the purpose of separation of gas mixtures. Thus requiring adsorbent selected gas to be adsorbed with high selectivity.

5.To a large adsorption capacity. Adsorption capacity size of many factors, including the size of the surface of the adsorbent, the reasonableness of the porosity and pore size distribution.2

III.The use of alumina ball:

1.Alumina ball petrochemical, fertilizer industry, widely used as catalysts, catalyst supports.

2.Activated alumina fluoride removal having sex, which is used as drinking water fluoride removal agent, industrial wastewater color and odor elimination of agents.

3.Lubricating oil vapor adsorption from contaminated oxygen, hydrogen, carbon dioxide, natural gas, etc., and can be used as catalysts, catalyst supports and the chromatography carrier.

4.Activated alumina ball can do adsorbents, desiccants, water volume, fast-drying, water can be reproduced and no swelling, no cracking, no deformation.

5.Activated alumina ball in monolithic refractories ingredients can improve the body density, mobility, strength, improve secondary mullite Dan Shengcheng amount, etc., reduce the amount of water and porosity.

IV.The physical and chemical indicators alumina ball:

Prior to use, a good product must first understand some of the basic parameters of parameters, which can be more convenient to choose their desired products.

A.Alumina balls chemical indicators:

Al2O3≥99%

SIO2≤0.2%

Fe2O3≤0.2%

B.Alumina ball physical indicators:

Bulk density g / cm3: 1.4-1.7

Cold crushing degree mpa: ≥9

Load softening starting temperature ℃ (0.1mpa, 0.6%): 1700

Reheating linear change% (1600 ℃ x3h): ± 0.3

Coefficient of thermal expansion x10-6 (room temperature -1300 ℃): 8.6

Thermal Conductivity w / (m.k) (average temperature of 800 ℃): ≤1.5

Maximum operating temperature ℃: 1800

Shizui Mountain City Jinlin Fused Alumina Refractories Co., Ltd. is a diversified manufacturing plants, research and development, production, sales and service in one. The company mainly produces fused alumina products, brown fused alumina, white fused alumina, silicon carbide, bauxite, alumina ball, garnet, aluminum oxide powder, zircon sand, castable and other professional production and processing company with a complete quality and scientific management system.

These are our company to introduce alumina ball, our company will continue to update information as we abrasive refractory related aspects, Thanks for reading, please continue to pay attention to our website Oh!
