This project is currently the best green process for the efficient production for butyl tuber,tire reclaimed rubber in a normal temperature and environmental friendly technique.
Technique Process
The process starts with 10-20 mesh tire rubber powder, firstly crush the rubber powder to 60-80 mesh by our special crushing equipment under room temperature. Secondly, the waste tire powder is subjected to the first stage of depolymerization at 100-150℃(use special mixer + special rubber additive). Thirdly, start the second stage of aging and plasticization regeneration, fourthly, the third stage of plasticizing is used to regenerate the sheet by a screw extruder or three sets of refiners to complete the process.
Output: 500kg/h
I. Characteristic:
The tire rubber powder or other rubber powders are plasticized (recycled) at a temperature lower than 100 ° C, and almost no exhaust gas is discharged in the whole process, which achieves green recycling process, and also realize continuous production and automatic control.
Technique process
Firstly, pulverize the 20mesh tire granules in to 60mesh at normal(room) temperature.
Mix the rubber powder, additives (specially supplied by Rv-tech) and softening oil with a special plasticizing equipment or mixer.
The second stage of plasticizing (regeneration) by a screw extruder with temperature below 100 °C.
Transportation and aging plasticizing (cultivation or development): The replasticized (recycled) rubber powder is discharged into a special closed container for parking and aging plasticization.（The above stage can completely replace high temperature and high pressure dynamic desulfurization tank and high temperature &normal pressure plasticizer in green environment.）
The kneading stage is same as the dynamic desulfurization tank process or the screw extruder tocomplete the entire regeneration process.
Modular combination, can build or rebuild existing equipment.
II. Cost analysis and product effectiveness
Since it is remodeled (regenerated) in a normal temperature (low temperature) environment, there is no large energy consumption, and no forced cooling device, so there is no artificial energy loss, 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 regenerative auxiliaries: 100 parts of rubber powder, 1-2 parts of auxiliaries, 5-10 parts of softening oil, etc., there is no big increase, so the product cost is consistent with the traditional method.
III. Cost analysis and product effectiveness
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 products, and at the same time can control the quality inspection at different stages. Therefore, green rubber replasticizing (regeneration) process is a perfect technology that combines energy saving, environmental protection, intelligence and automation.
