92 Alumina Ceramic Mosaic
Description
Technical Parameters
Products Description
The main component of 92 alumina ceramic mosaic is high-purity alumina, with an alumina content of over 92%. It is a wear-resistant ceramic lining material made by sintering at high temperatures above 1600 ℃. This product has extremely high hardness and density, far exceeding commonly used steel, and can significantly extend the service life of equipment such as conveying pipelines, chutes, hoppers, etc.
From the perspective of chemical stability, this product has good corrosion resistance to most acid, alkali, and salt solutions. This makes it applicable in fields such as chemical industry and food processing. It can also maintain stability in extreme environments of many chemical reactions and processing processes, ensuring production safety and efficiency.
characteristic
1. High hardness: The Rockwell hardness can reach HRA80~90, second only to diamond and far higher than ordinary wear-resistant steel.
2. Wear resistance: The wear resistance is about 248 times that of manganese steel, and the service life is greatly improved.
3. Lightweight structure: The density is about 3.6g/cm ³, which is only about half of steel, reducing equipment burden.
4. Corrosion resistance: Aluminum oxide has good stability and can withstand corrosive media such as acid, alkali, and salt, without the risk of electrochemical corrosion.
5. High temperature resistance: It can withstand hot environments up to 1250-1600 ℃, far exceeding the temperature that metal lining plates can withstand.
6. Long service life: In industries such as power plants and mines, the replacement cycle of traditional pipelines can be extended several times or even more than 10 years.
Application
92 Alumina Ceramic Mosaic is widely used in large equipment that requires wear-resistant protection, including:
Power plant coal transportation system: used as a lining for coal powder chutes, cyclone separators, and other parts, effectively resisting high-speed coal flow erosion, with a service life of over 10 years.
Cement and building materials industry: used as lining for pipelines, mills, and discharge troughs, significantly reducing equipment wear and reducing maintenance frequency by more than 60%.
Steel metallurgy: used for lining dust ducts, hoppers, and elevators to prevent particle erosion in iron ore and coal tar streams.
Mining and Chemical Industry: Suitable for crushing and screening, washing equipment, chemical tower lining and other scenarios, able to withstand the wear and chemical corrosion of grinding media.
In addition, this product is also commonly used in ports, railway loading and unloading systems, ceramic furnaces, and other fields. As long as there are high erosion and high wear material conveying conditions, this product can be considered for equipment protection. For example, a certain power plant used our Huao's 92% alumina ceramic mosaic tiles to renovate the chute, reducing the wear rate by more than 90% and significantly improving the equipment life.

Installation and maintenance recommendations
Installation guidance: During installation, the environment should be kept clean. First, check the flatness of the equipment surface and apply special ceramic adhesive (such as epoxy resin adhesive). According to the size of the lining board, it can be assembled in sequence, with virtual joints first and then fixed to ensure uniform gaps between the lining bricks and no dead corners left. Try to avoid severe impacts and collisions during the collage process. After completion of tiling, the adhesive should be cured under ambient temperature conditions, and it is recommended to wait for 48 hours before putting it into use.
Collision protection: Due to the high hardness but low toughness of ceramic products, hard object impact should be avoided during installation and use. Handle with care during transportation to prevent violent collisions with steel tools.
Maintenance: During normal operation, damaged local lining bricks can be replaced for maintenance, without the need to replace the entire piece. Regularly inspect the lining surface on a daily basis, clean up accumulated dust and sediment to reduce additional wear and tear. Promptly repair or replace any obvious wear or peeling to ensure continuous protection.
