This paper will outline the methods for enhancing the impact resistance of wear-resistant ceramic rubber composite liners.
Wear-resistant ceramic rubber composite liners offer an effective anti-wear solution for applications involving sliding and impact wear, such as those found in the cement, steel, mining, and iron and steel industries. However, in many practical applications, wear-resistant ceramic-rubber composite liners are also susceptible to brittleness and a lack of impact resistance.
Consequently, in practical applications, the constant improvement of the impact resistance of wear-resistant ceramic rubber composite liners will assist in the extension of the service life of the wear-resistant ceramic liner and the reduction of equipment downtime.
The steel backing plate ceramic rubber composite liner is composed primarily of alumina, with a rubber bonding layer and a steel backing plate. Following vulcanisation, the alumina ceramic exhibits high wear resistance (HRA ≥ 90), while the rubber provides cushioning properties. The steel backing plate enhances the overall mechanical properties of the wear-resistant lining plate, rendering it superior to conventional metal wear-resistant lining plates. Through the study of practical applications and the implementation of special processes, ceramic industry engineers can further enhance the general wear-resistant ceramic composite liner's impact resistance.
• The surface design of the liner incorporates a ceramic raised structure:
The ceramic raised structure serves to disperse the impact force, thereby reducing the likelihood of fragmentation of the steel backing plate ceramic rubber composite liner. This method is commonly employed in the industry to enhance the impact resistance of the ceramic liner.
• Increase the surface rubber exposure area of the composite liner:
Wear-resistant ceramic rubber composite liner due to ceramic impact resistance is weak, ceramic block between the reasonable gap design (or the use of cylindrical or hexagonal ceramic materials), can be through the liner surface exposed rubber, to enhance the overall impact resistance of the composite liner.
• Toughness enhancement treatment of alumina ceramics:
A certain proportion of zirconium oxide is added to the alumina, which can greatly enhance the impact resistance of the wear-resistant ceramics.
Alumina wear-resistant ceramic rubber composite liner through the ceramic block raised design, while increasing the surface area of vulcanised rubber, and with the help of alumina composite zirconium oxide and other processes, so that the wear-resistant ceramic rubber composite liner to further enhance the impact resistance, and therefore can better adapt to most of the heavy sliding abrasion, strong impact abrasion and other working conditions.
