How to prevent the aging of Rubber Rail Pads?

 

To prevent rubber rail pad aging, apply proper installation and maintenance practices, including regular inspections, correct fastening, and ensuring the pads are not exposed to excessive heat, sunlight, or damaging chemicals. Additionally, select high-quality pads that are manufactured with additives to improve resistance to aging and environmental factors.

Rubber Rail Pad
Technical Parameter Unit Value
Stiffness KN 90-130
Hardness Shore A 72-80 degree
Electronic Resistance Ω ≥ 106
Tensile Strength before Aging Mpa ≥12.5
Elongation before Aging % ≥250

 

Proper installation

 

  • Ensure correct alignment: Use a rail positioning fixture or laser calibration to ensure the pad and pressure plate are properly aligned with the rail. Incorrect alignment can cause uneven wear and tear.

 

  • Maintain sufficient clamping force: The clamping force is crucial for the pad's performance and longevity. Make sure the clamping force is sufficient during installation.

Environmental and material considerations

 

  • Limit exposure to extreme conditions: Protect pads from direct sunlight, UV rays, and high heat, which accelerate aging.

 

  • Use high-quality materials: When purchasing pads, choose those manufactured with additives like anti-aging agents, antioxidants, and other compounds that enhance resistance to heat, cold, and rot.

Rail pad functions

 

A rail rubber pad is essential in reducing shock and vibration in a rail system. The pad laid under the rail to ensure:

 

  • Load distribution over a larger surface

 

  • Elimination of load concentration and the resultant fatigue stresses

 

  • Centering of loads on the supporting element

 

  • Absorption of uneven contact surfaces between rail and support

 

  • Reduction of noise and vibration

 

  • Sealing between the bottom of the rail and the top of the support

 

  • Reduction of wear of the rail and its support
