Application of PTC-R Rubber Catalytic Reviving Agent

PTC-R rubber catalytic reviving agent has good reclaiming activation property. The reclaiming process is finished under the effect of oxygen and mechanical force, mainly depending on the break of the sulfur bond with few main chain breaks, so that it helps keep the original strength property of the rubber. This kind of rubber has higher physical and mechanical property, lower energy consumption and pollution and more simple technique than traditional reclaimed rubber.

Principle ：
As the atomic energy of the PTC-R rubber catalytic reviving agent and the sulfur atom lone pair electrons of the organic sulfur compounds form coordinate bond and make the S-S bond and S-C bond abate, the PTC-R rubber catalytic reviving agent has a catalytic effect on the optional break of the S-S bond and S-C bond. As PTC-R rubber catalytic reviving agent has more devulcanizing options, and there are few breaks of the chain C-C bond in the process of reclaiming, the reclaimed rubber has higher physical property.

PTC-R rubber catalytic reviving agent can be applied to the reclaiming of the soft rubber, rubber and plastic leftover bits and pieces, self-vulcanized rubber, etc.

Basic Technique:
Make the waste rubber shattered, clean and dry, and mix with PTC-R rubber catalytic reviving agent , fully blend the waste rubber on the stirring machine and then put them in the place under room temperature and low temperature, and then roll repeatedly on the open mill.

Process flow: primary sorting of waste rubber powder→ screening→ washing→ drying→ mixing→ pre-treating→ refining→ reclaimed rubber.
