The wear resistance of wear-resistant ceramic pipe mainly depends on the wear resistance of lining wear-resistant ceramics, and wear resistance refers to the ability of materials to resist mechanical wear, which is mainly determined by the hardness, strength and roughness of materials.


1.Hardness: the hardness of the material reflects the ability of the material to resist the material pressing into the surface. The higher the hardness, the shallower the depth of 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 hra85 or above, which is the basis of wear resistance of wear-resistant ceramic tubes.


2. Strength: high strength, which can provide good support for wear resistance and give full play to the ability of anti-wear and hard wear resistance, that is, strength and hardness complement each other. The bending strength of wear-resistant ceramics is 300-450 MPa and the compressive strength is 1200-2500 MPa, which further strengthens the wear resistance of wear-resistant ceramic pipes.


3. Roughness: the smaller the roughness value, the higher the fatigue wear resistance. Under certain circumstances, the ceramic surface roughness is related to the thickness of powder particles. Wear resistant ceramics have been polished for many times, and are supported by high-quality fine powder. The smoothness is very high, which adds a third guarantee to the wear resistance of wear-resistant ceramic tubes.

High hardness, high strength and smooth surface are the reasons for the wear resistance of the wear-resistant ceramic pipe. On this basis, there are also integrated forming, staggered joint connection and other methods to reduce the scouring of gas and powder on the wear-resistant ceramic pipe, so that the wear resistance of the wear-resistant ceramic pipe can reach a new level.
