| Abstract: |
| Ultra-high pressure water jet was used for breaking up and separating the radial tiret to recycle rubber powder，jet pressure（P），target distance（s）and moving speed（v）was taken as main factors，and the horizontal design and response surface analysis method of Design Expert software was used to optimize the process parameters of water jet in order to make the desulfurization effect of rubber powder optimization.The results showed that，ultra-high pressure water jet could make rubber powder desulfurization partly，and when the P was 180 MPa，s was 21 mm，v was 1 500 mm·min-1，the desulfurization effect was optimized，and the gel mass fraction of rubber powder was 0.828.desulfurization effect of rubber powder is at the jet pressure of 180MPa, the target distance of 21mm, the moving speed of 1500mm/min, powder gel fraction reduces to 82.80%. |
