Plasticizing Method Of Rubber Internal Mixer

2023-04-13

Rubber Internal Mixer is a kind of equipment for rubber processing, mainly used for mixing, masticating and processing rubber and other refining materials into various rubber products. The rubber internal mixer is composed of a frame, a machine head, a drum, a transmission system, an electrical control system, etc., and the drum is the core component of the rubber Internal Mixer.

The working principle of the rubber internal mixer is to put rubber and other mixing materials into the drum of the internal mixer, and through the rotation and friction of the drum, the rubber and other mixing materials are mixed and masticated. In the process of plasticizing, it is necessary to control the temperature, time of rubber mixing, the speed of rubber mixing machine and other parameters to ensure that the quality of the obtained rubber meets the requirements.

The plasticating methods of rubber internal mixer usually have the following types:

Hot soaking method: soak the rubber slices in hot water to soften and add them to the internal mixer for mastication.

Drying method: After the rubber slices are dried at low temperature, they are added to an internal mixer for mastication.

Wet drying method: Soak the rubber slices in water, then squeeze out the excess water, and then add them to the internal mixer for mastication.

Freezing method: freeze the rubber slices and then add them to the internal mixer for mastication. This method is suitable for high-viscosity rubber.

Roller method: Put rubber slices and other refining materials into the drum, and the rubber is masticated by the rotation and friction of the drum.

Extrusion method: Extrude the rubber paste, and make the rubber masticate under the extrusion of the extruder and the shear force.

Mixing method: Mix rubber and other mixing materials together, and then add them to the internal mixer for mastication.

Molding method: Add rubber paste into the mold, and plasticize the rubber into the desired shape through pressing and heat treatment.

It is necessary to select the appropriate masticating method according to the production demand and product characteristics, and also need to continuously adjust and optimize according to the actual production situation in order to achieve the best masticating effect and product quality. No matter which method is used, it is necessary to select the appropriate mastication method according to the characteristics of the rubber and the requirements of the desired product. At the same time, during plastication, it is necessary to pay attention to the control of parameters such as the amount of mixing material added, the mixing temperature, and the mixing time, so as to ensure that the quality of the obtained rubber meets the requirements.
