The wear resistance of the wear-resistant ceramic tube mainly depends on the wear resistance of the wear-resistant ceramic lining, and the wear resistance refers to the ability of the material to resist mechanical wear, which is mainly determined by the hardness, strength, and roughness of the material.
1. Hardness: The hardness of the material reflects the ability of the material to resist the material being pressed into the surface. The higher the hardness, the shallower the depth of the material intrusion, the smaller the volume of wear, and the higher the wear resistance. The alumina content of wear-resistant ceramics exceeds 92%, and the hardness reaches above HRA85, which is the basis for wear-resistant wear-resistant ceramic pipes.
2. Strength: With high strength, it can provide good support for resisting wear and give full play to the ability of anti-wear hard to resist wear, that is to say, strength and hardness complement each other. The flexural strength of wear-resistant ceramics reaches 300-450Mpa, and the compressive strength is as high as 1200-2500Mpa, which further strengthens the wear resistance of wear-resistant ceramic tubes.
3. Roughness: The smaller the roughness value, the higher the fatigue and wear resistance. The surface roughness of the ceramic has a certain relationship with the thickness of the powder particles under certain conditions. The wear-resistant ceramics have been ground and polished many times, and they are supported by high-quality fine powder. The smoothness is very high, which adds a third guarantee for the wear resistance of the wear-resistant ceramic tube.
4. High hardness, high strength, and smooth surface are the reasons for the wear resistance of wear-resistant ceramic tubes. On this basis, there are also integrated molding, staggered joints, etc. to reduce the erosion of wear-resistant ceramic tubes by gas and powder, so that The wear resistance of wear-resistant ceramic tubes has reached a new level.
