Mixing with rubber rubber or plastic refining machine will process raw rubber and compound into the mix, the production process of rubber processing is the most important. Essence is a complexing agent in rubber homogeneously dispersed in the process, with the granular agent was dispersed phase and continuous phase in rubber. Mixing can be used to open the machine, closed mixing machine and screw continuous mixer.
The rubber mixing process is essentially the complexing agent in rubber homogeneously dispersed in the process, with the granular agent was dispersed phase and continuous phase in rubber. In the process of mixing, the molecular structure, molecular weight and distribution of the rubber, and the aggregation state of the polymer were changed.
By mixing, the rubber and the complexing agent played a physical and chemical role, forming a new structure. Mixed rubber is a kind of dispersed system with complex structure. Because the rubber viscosity is very high, in order to make the coordination agent into raw and in which the uniform mixing and dispersion must be strongly with the help of mechanical shear mixing machine.
The utility model has the advantages of safe operation and low labor intensity, and is the most widely used.
Mixing requirements with agent dispersed in rubber, the formation of colloidal dispersion, so that the vulcanized rubber has the best performance. At the same time, there are some requirements for the plasticity of the mixture.
One and two stages mixing method. The former is a gradual addition of additives in rubber. The latter is the first adding softener and powder filler for refining crude mixed in the first stage, the glue is cooled and placed after a certain period of time, coupled with sulfur and accelerator second mixing
The rubber (rubber) with different agents (see rubber compounding) mixed evenly in rubber processing technology in rubber machine. In order to be able to cooperate with the addition of rubber powder agent, rubber must first the plastication, improve the plasticity and fluidity. The mixing process is the basic process of rubber processing. The quality of the mixture after adding the agent has a decisive influence on the process performance and product quality.
