Example Embodiment
[0014] Example one
[0015] The method of continuous desulfurization of rubber under normal pressure is to pulverize the rubber, then add softener and activator to the pulverized rubber powder and mix them uniformly, and then desulfurize the uniformly mixed materials. The desulfurization includes the following steps:
[0016] The material is continuously sent to the desulfurization pipeline through the fluidized bed for desulfurization. The desulfurization pipeline has a diameter of 180mm and is divided into five equidistant sections. Each section of the desulfurization pipeline adopts external heating. According to the flow direction of the material, each section of the pipeline is heated by electromagnetic induction. The power is 25kw, 25kw, 15kw, 15kw, 10kw, the inside of the desulfurization pipeline is normal pressure, the length of each desulfurization pipeline is 3m, and the material flow time between the entire desulfurization pipeline is 18min. After the material comes out ...
