EBR System For PCR Tire

The Electron beam processing system(EBR System) is used to optimize tire components performance,lessen fabric tensile deformation,improve uniformity of material arrangement and lower penetration rate down to nearly zero through changing molecular structure by radiation.

Quality improvement:It helps to avoid the mutual penetration of the transition layer and the carcass ply, which can effectively correct the problem of exposed cords in cavity of PCR tires.

Cost reduction:Thin or even cancel transition layer by optimizing the radiation dose, thereby greatly reducing the production cost.

Energy-saving:It can reduce the weight of the tire and the rolling resistance , which helps to achieve fuel saving and exhaust gas emission reduction.

1.Higher stability:The irradiation window adopts scanning structure, energy and electron beam stability is within ±2%,which ensures the material receives radiation dose uniformly;Leakage dose outside the shield is less than 1µSvh when tested within a distance of 100mm.

2.Smaller occupied space:Modularized layout enables equipment being embed in production line easily and without changing.

3.Intelligent control:It is installed with on-line infrared temperature measurement system, material cooling system and PLC Adjustable Speed Drives System, realizing EB radiation processing working with calender synchronously.

4.Simpler structure:It has structural design by R&D, which leads to maintaining easily and with a low maintenance cost.

5.Faster radiation:It has a short time for the irradiation, which is only 3 seconds taken to complete crosslinking, realizes calendered fabric being radiated by EB processing system while calendered fabric is conveyed on the production line.
