Product Description

Alumina balls, also known as modern water-purifying activated alumina, are porous, highly dispersible solid materials and have the characteristics required for catalysts, and are therefore commonly used as catalysts in the chemical industry. The following is a brief introduction to the use and properties of alumina balls.

Product Usage

In the petrochemical and fertilizer industries, it is widely used as a catalyst and catalyst carrier. Modern water-purifying activated alumina has adsorption characteristics and is therefore used as a desiccant for gases and liquids, as an adsorbent for gas purification, as a deionizing agent for drinking water, as a color and odor eliminating agent for industrial sewage.

It can be used together with household fluorine removal cylinders, and is an ideal drinking water defluoridation device in the family. The defluorination filter material can also be used together with the fluorine removal device of the water plant or the fluorine removal device for industrial use. Activation of fluorine removal filter for household fluorine removal equipment: dispose of aluminum sulfate solution (3 liters of water, 0.3 kg of solid aluminum sulfate), put alumina (AL2P3) defluoridation filter into the above solution, soak for 5-10 hours to discard The liquid (should be properly stirred during soaking), and then washed 3-5 times with water, each time with water about 2 liters, or regenerated by pH adjustment, the pH is controlled at 7.5. Activated alumina defluorination filter can be used continuously for 6-8 years. When the surface appears yellowish brown, the effect of removing fluorine is obviously reduced. This is caused by impurity pollution in the water. Therefore, it is best to treat it once every half a year with 3% dilute hydrochloric acid. The method of operation is the same as the regeneration method.

Physical properties

Moreover, it is required that the dissolution rate of alumina in the cryolite melt is fast, the bottom of the electrolytic cell tank is deep and deep; the heat insulation of the shell on the electrolyte is good; the moisture is not absorbed in the air, the flying loss is small, the fluidity is good, and the transportation is convenient. And to facilitate the automatic feeding of the electrolytic cell. All of these properties depend on the physical properties of the alumina.

The indicators used to characterize the physical properties of alumina are: angle of repose, α-Al203 content, bulk density, particle size and specific surface area, and wear coefficient.


Use and properties of alumina balls

1. The angle of repose. The alumina angle of repose refers to the inclination of the material naturally accumulating on a smooth plane. The alumina with a larger repose angle is more soluble in the electrolyte, and can be well covered on the electrolyte crust during the electrolysis process, and the flying loss is also small.

2. A-Al2O3 content. The content of a-Al2O3 in alumina reflects the degree of alumina roasting. The higher the degree of calcination, the more a-Al2O3 content, the hygroscopicity of alumina decreases with the increase of a-Al2O3 content. Therefore, alumina for electrolysis is required to contain a certain amount of a-Al2O3. However, the solubility of a-Al2O3 in the electrolyte is inferior to that of Υ-Al203.

3, the weight. The bulk density of alumina refers to the weight of a unit volume of material in a natural state. Aluminium, which generally has a small bulk density, facilitates dissolution in the electrolyte.

4. Particle size. The particle size of alumina refers to the degree of its thickness. The particle size of alumina must be appropriate, too coarse in the electrolyte to dissolve slowly, or even precipitate; the rules are easy to fly loss.

5. Specific surface area. The specific surface area of alumina refers to the total surface area of the sum of the outer surface area per unit weight of the material and the surface area of the inner pores. It is an important indicator of the level of material activity. Alumina having a large specific surface area has good solubility in an electrolyte and is active, but is hygroscopic.

6, wear coefficient. The so-called wear coefficient is the percentage change of the fractional content in the sample after the alumina is rubbed in a fluidized bed under controlled conditions. The wear coefficient is a physical indicator of the strength of alumina.

According to the physical properties of alumina, alumina can usually be divided into three types: sand, flour and intermediate. These three types of alumina have large differences in physical properties. The sand-like alumina has a small bulk density, a large specific surface area, a slightly smaller angle of repose, and a smaller amount of a-Al2O3, and the coarse particles are more and more uniform, and the strength is higher. Flour-like alumina has a large bulk density, a small specific surface area, contains a large amount of a-Al2O3, more fine particles, and poor strength. The physical properties of the intermediate alumina are somewhere in between.
