The wear resistance of in mould coating refers to the ability of the coating to resist friction, wear and other mechanical stresses during processing. Its wear resistance is mainly affected by the following factors:
Coating material:
Common wear-resistant coating materials include ceramics, polyurethanes, and various metal coatings. Different materials have different hardness and wear resistance characteristics.
Coating thickness:
Generally speaking, the thicker the coating, the better its wear resistance, but too thick may lead to reduced adhesion.
Coating adhesion:
The adhesion between the coating and the substrate affects the wear resistance of the coating. Good adhesion can reduce the risk of coating peeling.
Processing conditions:
Processing temperature, pressure, and speed can affect the degree of wear of the coating. For example, high temperature or high pressure may accelerate wear.
Use environment:
The wear resistance of the coating will vary in different working environments, such as corrosive media or extreme temperature conditions.
Surface treatment:
The wear resistance of the coating surface after special treatment, such as polishing, sandblasting, etc., can be further improved.
Common test methods include friction test, wear test, etc., through which the wear resistance of the in mould coating can be evaluated and necessary improvements can be made.
