The structure of the ceramic-rubber three-in-one plate

The ceramic-rubber three-in-one plate consists of three layers in total: the ceramic layer, the rubber layer and the steel plate layer.

Ceramic layer: Made of alumina ceramics. The ceramic is composed of imported high-quality powder and is produced through high-temperature firing to form special corundum ceramic, with a Mohs hardness of 9. By adjusting the production formula and process, the alumina ceramics maintain high hardness and wear resistance while also having a certain impact resistance. Moreover, some ceramics adopt a unique spherical design, such as the 95 red alumina ceramic with a hemispherical protrusion. When impacted by large pieces of material, the spherical surface can disperse stress, reduce local stress concentration, and prevent the ceramic from breaking due to brittleness.

Rubber layer: Usually made of highly elastic natural rubber or synthetic rubber with special properties. Rubber has excellent elasticity and deformation capacity. When subjected to impact, it can absorb a large amount of impact energy through its own elastic deformation, reducing the vibration transmitted to the steel plate and ceramic layer, alleviating the direct impact of materials on the ceramic, and playing a role of buffering and vibration reduction. The tensile strength of the rubber layer exceeds 15 MPa, and the elongation rate exceeds 300%. It combines flexibility and tear resistance, and can continuously exert the buffering effect.

Steel Plate Layer: The steel plate possesses remarkable toughness and ductility. As the base material for the liner, it provides the necessary strength and support for the entire liner. When subjected to impact, the steel plate can withstand certain deformation without breaking, effectively protecting the ceramic liner and also enhancing the overall impact resistance of the liner, ensuring the structural integrity of the liner during impact.

The composition structure of the three-in-one ceramic-rubber plate:

Composite structure: Through the heat vulcanization process, the toughening ceramic sheet is vulcanized into a steel plate groove filled with special rubber, thereby enabling the ceramic, rubber and steel to be closely integrated into a single unit. This composite structure enables the three materials to work collaboratively with each other, fully leveraging their respective advantages. When subjected to an impact, the energy can be successively transferred and dissipated among the three materials, rather than being solely borne by a single material.

Fastening with bolts: The steel plate slots are equipped with countersunk bolts. Each ceramic piece has a through-hole bolt that penetrates through the bottom steel plate and is firmly welded. This design not only makes the connection between the ceramic and the steel plate more secure, preventing the ceramic pieces from falling off during the impact process, but also, when subjected to impact, the bolts can play a certain anchoring role, further enhancing the impact resistance of the liner plate, enabling the liner plate to better withstand the impact of large pieces of materials. https://ceramiclinings.com/

Analysis of the Rubber-Ceramic three-in-one Composite Plate Technology: Materials, Processes and Industrial Applications

图片
In the field of industrial wear resistance, traditional single-material solutions are no longer sufficient to meet the complex requirements of high wear and strong impact in various working conditions. The rubber-ceramic three-in-one composite plate , as a revolutionary solution, has achieved a breakthrough in material performance through a three-layer composite structure design: the ceramic layer resists wear, the rubber layer absorbs impact, and the steel plate provides support. This composite wear-resistant material is now widely used in heavy industries such as power, mining, and metallurgy, and has become one of the core technologies for extending equipment lifespan and reducing maintenance costs. The rubber-ceramic three-in-one composite plate is composed of wear-resistant ceramics, rubber and metal steel plates. The ceramic layer mainly uses high-purity (92%, 95%) alumina powder as the raw material, which is formed by dry pressing or isostatic pressing. After being sintered at a...

How to reduce the production cost of alumina wear-resistant ceramics?

图片
The production cost of alumina wear-resistant ceramics is high. In order to reduce the production cost, the following aspects can be considered: I. Raw material selection 1. Select cost-effective raw materials: Under the premise of ensuring product quality, select alumina powder with relatively low price but satisfactory performance, such as industrial alumina or calcined alumina instead of high-purity alumina powder. At the same time, we can explore the use of a mixture of alumina and other ceramic materials to reduce costs through reasonable proportions. 2. Joint procurement of raw materials: Cooperate with multiple companies for joint procurement and use economies of scale to reduce procurement costs. II. Process optimization 1. Optimize the preparation process: Improve production efficiency, reduce energy consumption and waste generation by improving the preparation process. For example, use advanced sintering technology and mold design to shorten sintering time and reduce energy ...
