The pulverizing, ash, dust removal, and coal conveying systems of coal-fired power plants are constantly affected by friction, corrosion, collision, impact and other factors of the medium during the operation of the equipment, and the system is prone to leakage, causing environmental pollution. For this reason, each power plant has adopted different leakage control methods accordingly; among them, wear-resistant ceramic liner is an ideal leakage control material, and its wear resistance, practicability and economy are superior to other wear-resistant materials.
The wear-resistant ceramic lining is made of Al2O3 as the main raw material, and then some metals are used as the oxide as the solvent, and is made of corundum ceramics after being calcined at a high temperature of more than 1,000 degrees, so the wear-resistant ceramic lining does not matter. It is very high in hardness and wear resistance. Under normal circumstances, it is no problem to use it for up to 10 years.
The installation of the wear-resistant ceramic lining plate is mostly by using strong adhesive to paste the wear-resistant ceramic on the surface of the mechanical spare parts. Provide protection.
Wear-resistant ceramic liners are industrial wear-resistant, impact-resistant and corrosion-resistant materials. Shock resistance and thermal expansion and contraction: the thermal expansion coefficient of viscose is between steel and ceramics, which can well adjust the extrusion of ceramics due to the inconsistent thermal expansion of ceramics and steel; at the same time, a variety of flexible fibers are added to the adhesive , to ensure that the ceramics will not fall off during long-term operation under the environment of vibration and frequent thermal expansion and contraction.
The wear-resistant ceramic lining plate can also be used as a wear-resistant material for the material conveying equipment of steel mills and power plants to flow through the surface of the pipeline. Its main function is to effectively resist the impact on the pipe wall and the corrosion of chemical substances when the material passes through. The thermal shock effect caused by the action and the passing of the material greatly reduces the wear and tear on the inside of the equipment components.
