Factors affecting the wear resistance of polyurethane elasticity

The author of "Factors Affecting the Abrasion Resistance of Polyurethane Elastomers" is Liu Liangbing, Department of Materials Engineering, Taiyuan Institute of Technology, to study the factors affecting the abrasion resistance of polyurethane elastomers. The article first introduces the basic concept of wear, the form of rubber wear (wear wear, fatigue wear, curl wear, corrosion wear), as well as domestic and foreign wear test methods and standards and factors affecting wear resistance, and introduces several wear testing machines. , including Akron Abrasion Testing Machine, Roller Abrasion Testing Machine, Taber Abrasion Testing Machine, NBS Abrasion Testing Machine, Taber Abrasion Testing Machine, etc. Furthermore, the impact of chemical structure and additives on the wear resistance of polyurethane elastomers was discussed, and the polyurethane elastomers obtained by different synthesis methods (mixing polyurethane (MPU), cast polyurethane (CPU), thermoplastic polyurethane (TPU) were compared. ) wear resistance, and wear values ​​obtained by different test methods.
