Embodiment 1
[0015] The method of continuous desulfurization of rubber at normal pressure is to crush the rubber, then add softener and activator to the crushed rubber powder and mix them uniformly, and desulfurize the uniformly mixed materials. The desulfurization treatment includes the following steps:
[0016] The material is continuously fed into the desulfurization pipeline through the fluidized bed for desulfurization. The diameter of the desulfurization pipeline is 180mm, and it is divided into five sections with equal distances. 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 powers are 25kw, 25kw, 15kw, 15kw, 10kw respectively, the inside of the desulfurization pipeline is normal pressure, the length of each desulfurization pipeline is 3m, and the flow time of materials between the whole desulfurization pipeline is 18min. After the material...

[0018] The method of continuous desulfurization of rubber at normal pressure is to crush the rubber, then add softener and activator to the crushed rubber powder and mix them uniformly, and desulfurize the uniformly mixed materials. The desulfurization treatment includes the following steps:
[0019] The material is continuously fed into the desulfurization pipeline through the fluidized bed for desulfurization. The diameter of the desulfurization pipeline is 180mm, and it is divided into five sections with equal distances. 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 powers are 25kw, 25kw, 15kw, 15kw, 10kw, the inside of the desulfurization pipeline is normal pressure, the length of each desulfurization pipeline is 4m, and the material flow time between the whole desulfurization pipeline is 20min. After the material comes out of the...
