Product Description

Hebei RVTECH Co., Ltd and Shijiazhuang For Rubber Industry Co., Ltd. have successfully developed a Mechanochemical reactor of rubber screw refining machine after more than ten years of hard work. The company's research and development team is broad-minded and persistent. After thousands of trials, we finally successfully produced MRSRM and obtained three patents.
The most effective comprehensive utilization of waste rubber is to produce regenerated rubber. The traditional method is to produce it under the combined action of heat energy, mechanical force and chemical additives. The mechanochemical reactor of rubber screw refining machine developed by the team focuses on the recycling of rubber scraps and rubber powder. It can complete the regeneration of saturated rubber without adding any additives, and can easily restore the replasticity of waste rubber to achieve a closed circuit of the factory without waste.

For natural rubber and general synthetic rubber, it can be achieved through the following processes:

1. Pulverize and mix waste rubber scraps or rubber powder on a specialized kneading machine, add 0.5 parts of rubber regeneration additive RV-RB (semi-high temperature aid), 10-15 parts of softening oil, knead to 120 ° C, and discharge cool down.
2. Put the mixed rubber powder into the Mechanochemical reactor of rubber screw refining machine MRSRM, and cool after reaction.
3. Enter the mill (refiner) and output the rubber sheet, complete.
The whole production process does not require heating, the temperature is below 120°C, there is no waste gas and wastewater pollution, the replasticized rubber has no smell, and the Mooney viscosity is low, which truly realizes green recycling.
Technique Process

First, Put the rubber powder, RV-RB,softened oil and resin into a special kneader, mix and knead for 10-15 minutes, and discharge when the temperature reaches 150 °C.
Second,The discharge material enters the conveying screw to be cooled in the cold mixer and parked.
Third,After cooling and parking, directly enter the screw refiner (MRSRM) to refine for one time, and then enter the ordinary refiner to produce chips to complete the regeneration process.
Fourth, It is also possible to add rubber vulcanization aids after discharge from the screw refiner and mix them in the internal mixer, and then directly vulcanize them into solid tires or rubber sheets.

Applicable materials:

waste tire rubber powder, waste rubber trim rubber powder, natural latex gloves, condoms, balloons, nitrile gloves, neoprene capsules, etc.
