Open mill plastication is generally affected by temperature, plastication time, roller speed ratio, roller distance, and rubber loading. Open mill plastication belongs to low-temperature mechanical plastication. The plastication temperature is generally below 55°C. The lower the temperature, the lower the temperature. The better the plasticizing effect.
Open mixer plastication belongs to low-temperature mechanical plastication. The plastication temperature is generally below 55°C. The lower the temperature, the better the plastication effect. During the plastication process, the longer the plastication time, the higher the temperature of the rubber material. In order to To improve the masticating effect, generally after masticating for a certain period of time, the rubber must be cooled and parked for a certain period of time before being masticated again.
Plasticizing with an open mill is mainly through the shearing and extrusion of two relatively rotating rollers on the rubber material, so that the original macromolecular chain of the rubber material is interrupted, thereby reducing the elasticity and improving the plasticity. , It is beneficial to the subsequent processing and mastication principle 4. Reasons for mastication · Raw rubber is a linear polymer, which is in a high elastic state at room temperature.
