Description

Technical Field

[0001] The utility model relates to the technical field of butyl recycled rubber, and particularly relates to an on-line characterization device for testing the Mooney viscosity of butyl recycled rubber. Background Technique

[0002] China is the world's largest consumer of rubber materials and also the largest producer of waste rubber. Coexisting with the "white pollution" of plastic garbage bags and disposable lunch boxes is the "black pollution" formed by waste rubber, especially waste tires. In the situation where a large amount of waste rubber needs to be processed and the market demand for rubber materials is increasing day by day, the research on waste rubber recycling technology becomes more and more important. The technologies for recycling waste rubber include desulfurization by open mill, spiral (including single spiral and double spiral) high-temperature continuous desulfurization, continuous desulfurization by extruder, microwave desulfurization, and ultrasonic desulfurization, etc.

[0003] For example, the patent application with the application number CN201420338141.X includes a connecting body, a temperature measurement component, a computer, a heating sleeve, and screws. The connecting body is arranged between the barrel and the head of the extruder. Both ends of the connecting body are respectively connected to the barrel and the head of the extruder by screws. A heating sleeve is arranged on the outer periphery of the connecting body. The temperature measurement component extends into the flow channel of the connecting body, and the temperature measurement component is signal-connected to the computer. The method is to first establish a quantitative relationship equation between the Mooney viscosity of the recycled rubber and the temperature of the rubber compound when the temperature of the rubber compound is controlled within a preset temperature range, then measure the temperature of the rubber compound online through the temperature measurement component, and then calculate the corresponding Mooney viscosity of the recycled rubber through the quantitative relationship equation. The utility model is used for testing the Mooney viscosity of the recycled rubber obtained by desulfurizing waste rubber, and can realize online measurement to obtain appropriate Mooney viscosity of the recycled rubber and high performance of the recycled rubber without affecting the continuous extrusion desulfurization process.

[0004] However, when the above test device is in use, after the extrusion process is stable, the temperature of the rubber compound measured by the temperature sensor is recorded and a certain amount of recycled rubber sample is taken out from the outlet of the head.

Hold the limit handle 23 and take out the sampling boxes 7 from the L-shaped plates 6 through the limit frame 22 and release the extrusion on the baffle 9. The sampling spring 10 squeezes the baffle 9 to occlude the sampling groove 15. Take the sampling boxes 7 off the limit frame 22.
