Does the tire cord need to be lubricated?
1 Answers
Tire cord needs to be lubricated. The cords inside the tire are called tire cords. Related introduction: 1. Viscose cord: Fatigue-resistant, heat-resistant, and has good dimensional stability, but viscose cord has the disadvantage of being prone to moisture absorption and reduced strength after moisture absorption. Mainly used in radial passenger car tires. 2. Polyamide cord: High strength, good impact resistance and fatigue resistance, but poor dimensional stability and poor adhesion to rubber. When used, it must undergo dipping and heat stretching treatment to improve its dimensional stability and adhesion. Widely used in tires for trucks, aircraft, as well as in belts and hoses. 3. Polyester cord: High strength, large initial modulus, good thermal shrinkage and dimensional stability, but it generates high heat during fatigue, is prone to amination and hydrolysis, which reduces strength, and is difficult to bond with rubber. To improve adhesion, surface activation treatment and dipping are required. Widely used in passenger car tires. 4. Aramid cord: High strength and modulus, better high-temperature resistance and dimensional stability, but high cost and poor adhesion to rubber. Suitable for high-performance tires such as luxury cars, military vehicles, and aircraft.
