Principle:
a subject that when the solid material is added with mechanical energy, its solid state, crystal structure, etc. change, as a result that the physical and chemical property change is called mechano-chemical. The rubber machinery sheering and shattering process is accompanied with the impact of the mechano-mechanical, when the force works on the waste rubber, the force initiation is produced, and the active particles are generated, at the same time creating force splitting, and generating molecule chain break sheet with big free radicals property ① . When degrading the vulcanized rubber, the free radicals are on the C-C= bond instead of C-S bond, but when there is C-Sn-C bond, 30% C-C bond will be directly destroyed, while 70% is chain broken caused by the shift of the unpaired electron to the sulfur created by breaking the C-C bond ② .The splitting

does not always happen on the weakest bond, but can also happen on the  stronger bond, when there is weaker C-S bond, it  can split on the C-C bond ③ .As the atomic energy  of the RMCD rubber  mechano-chemical chain  scission  depolymerizing agent and the lone pair  electrons of the sulfur atoms among the sulfur  organic compound form a coordination bond, making S-S bond and S-C bond be weaker,  and cutting S-S bond and S-C bond under the  mechanical force and in this way we can reclaim  the waste tire rubber powder. As the rubber mechano-chemical chain scission depolymerizing  agent RMCD has many chain-break options, the break of the rubber molecule main chain C-C bond  is small, so the revived rubber keeps higher  physical property.
