Extruded Rubber Recycling Technique

I.Characteristics:

Achieve rubber powder or other rubber powder re-plastic (recycle) through a temperature lower than 100 °C, and there is almost no exhaust gas is discharged in the whole process, which achieves green rubber recycling and realizes automatic control and continuous production.

II.The process route

i）First, pulverize the 20meshes tire granules to 60 meshes, and we have achieved pulverizing 20mesh rubber granules to 60 meshes at normal temperature.

ii）Mix rubber powder, additives (specially supplied by Rv-tech) and softening oil with a special re-plastic machine or mixer.

iii）Using the screw extruder for the second stage of plasticizing (regeneration) with a temperature below 100 ° C.

iv）Transport and cultivation (or development): discharge the plasticized (recycled) rubber powder into a special closed container for parking and cultivation (or development). (The above stage can completely replace high temperature and pressure dynamic desulfurization tank and high-temperature normal pressure rubber recycling equipment in a green environment.)

v）The kneading stage is the same as the dynamic desulfurization tank process or the screw extruder sheeting process and then complete the entire regeneration process.

vi）Modular combination, to build and rebuild existing equipment.

III . Cost analysis and product effects

Since it is a re-plasticized(regenerated) process in a normal temperature (low temperature) environment, so there is no large energy consumption, and there is no forced cooling device, so there is no artificial energy loss, so the energy consumption and labor costs are not increased, which is consistent with the cost of the conventional method.

The ratio of rubber powder, softening oil, and special recycling additives: 100 PHR of rubber powder, 1-2 PHR of recycling additives, 5-10 PHR of softening oil, etc., and the quantity is no big increase, so the product cost is consistent with the traditional method.

IV . Automation and intelligent applications

By adjusting the equipment and route, we will realize the whole process of automatic control and segmentation regeneration (modularization), which can realize the requirements of different users for their products, and at the same time can control the quality inspection at different stages. Therefore, green rubber re-plastic（recycle）technique is a perfect technology that combines energy-saving, environmental protection, intelligence, and automation.
