Activated aluminium oxide is a white, and spherical porous material with the property of being non-toxic, odourless, and insoluble in water & ethanol. The particle dimensions are uniform, the surface is even, the mechanical strength is high, the ability of moisture absorption is very strong and the ball is not split even after absorbing water. Activated aluminium oxide has many capillary channels and a very large surface area, which can be used as an adsorbent, and catalyst. At the same time, it is determined according to the division of the adsorbed substance. It has a very strong affinity for water, acetic acid, alkali, etc. Activated aluminium oxide is a kind of micro-water deep desiccant & an adsorbent for adsorbing polar particles.
Under certain operating circumstances and regeneration conditions, its drying deepness is as high as the dew point temperature and it is a well-organized desiccant for the deep drying of trace water. It is extensively used in gas and liquid stage drying of the petrochemical industry, oxygen production industry & automatic instrument air, pressure swing adsorption in air parting industry, etc. Due to the higher net heat of the monomolecular layer, it is very appropriate for heatless regeneration devices.
Activated aluminium oxide is a white porous particle with uniform particle size, smoother surface, higher mechanical strength, and stronger hygroscopicity. It is made of higher purity alumina through scientific preparation & catalytic finishing. It can be used as a fluoride remover for fluoride water, making it a molecular adsorbent with a very huge specific surface area. When the pH value & alkalinity of the raw water are lower, the fluorine removal capacity is higher. It can be used for fluorine removal, sewage decolorization, deodorization of water, and industrial devices. Activated aluminium oxide is manufactured from aluminium hydroxide by dihydroxylation that produces a highly porous material and this material can have a very high surface area. The compound is used as a desiccant to keep all things dry by absorbing water from the air and as a carrier for the slower release of absorbed chemicals. It has a higher surface-area, due to the many pores that it has.
Applications of activated aluminium oxide
Activated aluminium oxide is used for a wide range of adsorbent & catalyst applications including the adsorption of catalysts, in hydrogen peroxide production, as a discerning adsorbent for chemicals including arsenic, in sulphur removal from gas streams. It is classed as an inert material & a filler for numerous applications. Our activated aluminium oxide is manufactured with the latest technology to ensure higher quality properties such as Adsorption, Pore Volume & Mechanical strength.

In addition, domestic carbon brick aggregates are mainly anthracite and artificial graphite.
The structure appears loose; while foreign carbon bricks use anthracite as the main aggregate, anthracite has a high degree of graphitization, a dense surface, few cracks, uniform distribution of aggregate particles, and a compact structure.Silicon carbide products are repeatedly heated in the oxidizing medium without foaming into slag.
This performance can be measured by the heat resistance index.
Silicon carbide products containing 10% bound clay have a heat resistance of 1300 ° C, but the limit temperature for proper use should be lower than its heat resistance of 50 ~ 100C, so it should be used as little as possible when mixing.
In 1990, world bauxite output was 111.85 million tons.Special refractory plant designed a high temperature tunnel kiln with a length of 72.55m and burning natural gas for calcining the body of vacuum extrusion molding.
A feeding pipe and a water spraying pipe are installed vertically above the disc.
