Example Embodiment
[0024] Example 1:
[0025] To produce a spacer with a size of: inner diameter × outer diameter × length (36 ± 0.5) mm × (46 ± 0.5) mm × (2000 ± 20) mm, the specific steps and process parameters are as follows:
[0026] 1. Extrusion of semi-finished products: The compounded rubber is extruded through an extruder. The temperature of the extruder is set as follows: the temperature of the die head is 60 °C, the temperature of the extrusion section is 55 °C, the temperature of the plasticizing section is 45 °C, and the temperature of the feeding section is 45 °C. The temperature was 45°C.
[0027] 2. Microwave vulcanization: The microwave device has 5 microwave sections, the first 2 microwave sections are turned off, and the last 3 microwave sections are turned on. The microwave power of each section is set to 1000W, that is, the total power is 3000W, and the temperature of the microwave section is set to 150 ℃ . The temperature of the heating section was set to 170°C, 190°C, and...
