Performance comparison of four wear-resistant materials

1. Polyethylene molecular material: Polyethylene molecular material has the characteristics of good wear resistance, low friction coefficient, good sliding performance, corrosion resistance, good insulation performance, light texture, easy processing, and good shock absorption and noise reduction. The general thickness is 10~30mm. Its hardness and wear resistance meet the requirements. But it is brittle, not shock resistant, and expensive.

2. Cast iron: Cast iron is a commonly used wear-resistant material in engineering. According to the carbon content, cast iron is divided into three types: gray cast iron, and white cast iron. The hardness is between HRA70-80, the texture is hard, but it cannot be cut, the welding is difficult, and it cannot withstand heavier impact loads.

3. Stainless steel: The main material of the stainless steel lining plate is aluminum-chromium alloy, its hardness is 2~3 times that of the cast iron lining plate, and the service life is 12 times that of the cast iron lining plate. Obvious results have been achieved in all aspects. The cost of the stainless steel liner is high, and frequent replacement is likely to cause great waste. Because it is different from the material of the chute, it is more troublesome in welding.

4. Wear-resistant ceramics: Wear-resistant ceramic lining is currently the most widely used chute lining material. It uses alumina as raw material and converts it into an octahedral crystal structure at a high temperature of 1700 °C. The α-alumina, not only hardness reaches HRA88, second only to diamond, its density ≥3.9g/cm3, flexural strength>350MPA, impact toughness ≥2.2J/cm², elastic modulus>317GPA, with strong impact resistance Capability is the common choice of performance and price.

FQA

Is ceramic resistant to wear?

Wear-resistant ceramics are special corundum ceramics made of Al₂O₃ as the main raw material, rare metal oxides as the flux, and calcined at a high temperature of 1,700°C.

Does ceramic have high wear resistance?

The wear resistance of ceramics is very high. After experiments, it is found that the wear resistance of wear-resistant ceramics is 266 times that of manganese steel. It has strong wear resistance and can be used with complete confidence.

Is ceramic tougher than steel?

The hardness of ceramics is higher than that of iron
