How to improve the wear resistance of air spring rubber airbags?
Today, the gap between domestic air springs and imported air
springs is getting smaller and smaller. Proper use and attention to
maintenance are ways to extend the life of air springs. Maintenance
serves to extend the life of the air spring. It must be based on
the superior quality of the air spring rubber bladder itself. In
the production process, what methods can improve the wear
resistance of air spring rubber airbags? In addition to the most
basic work in the vulcanization process, you need to pay attention
to the following points:
1. The smaller the particle size of the general filler, the lower
the dispersibility, surface activity and structural structure, and
the worse the wear resistance. The optimum amount is BR90-100
parts, the oil-filled SBR is 60-70 parts, and the SBR and IR are
50-. 55 parts, NR is 45-50 parts.
