Alumina wear-resistant ceramics have high hardness and good wear resistance, so ordinary cutting tools cannot cut alumina wear-resistant ceramics. Wear-resistant ceramics use AL2O3 as the main raw material and rare metal oxides as flux. It is a product made of special corundum ceramics baked at high temperatures, and then combined with special rubber and high-strength organic adhesives. So what are the factors that affect the strength of alumina wear-resistant ceramics?
1. Particle size of ceramic raw materials: When preparing ceramic raw materials, only when they are ground to sufficient fineness can the color and fineness of the finished product be guaranteed. A good finished product will have the texture of jade from the outside, and it will be tightly arranged, dense, and dense, wear-resistant ceramics are also strong.
2. Pretreatment of ceramics. Many manufacturers omit this step or shorten the pretreatment time of ceramics due to cost considerations. However, often cost-saving practices will directly lead to a decrease in the strength of the finished wear-resistant ceramics, which is prone to cracking and shock proof.
3. Firing temperature and stability. Different materials have different firing temperatures for ceramics. If the temperature is too high, the molding time of the ceramics will be too short, and the relative toughness of the ceramics will be insufficient. If the temperature is too low, the ceramics will not be burned thoroughly, and the internal and external quality will be different. Nowadays, most domestic ceramics are fired in tunnel kilns and shuttle kilns. The temperatures at the kiln head and kiln tail are also inconsistent, so the products must be matched according to the actual situation during production.
The above are the factors that affect the strength of alumina wear-resistant ceramics. I hope it will be helpful to everyone.
