How to control the mixing process of Rubber Kneader?

Rubber Kneader poor intuitive when mixing rubber, in order to achieve optimal mixing state must take reliable scientific means of control of the mixing operation.

 

There are mainly three control methods:

 

1. Time control method

According to test of optimum kneading time is as the rubber kneader mixing process of time parameter control. Mixing operation to achieve the specified time will be the end of the mixing immediately rubber row can be manual and automatic control, and rubber row time standards commonly used the carbon black dispersion. However, due to the influence of the kneading process conditions and the raw material performance etc. factors such as fluctuations difficult to ensure the uniformity of the quality and stability of the kneading.

 

2. Temperature control method

According to test of optimum kneading temperature is as the rubber kneader mixing process of time parameter control. Mixing operation to achieve the specified temperature will be the end of the mixing immediately rubber row can be manual and automatic control, rubber kneader internal temperature and then by a little time to stop the rise equilibrium, the temperature at the moment can be as rubber row temperature standard. This method is a control method, developed in accordance with the principles of the rubber material kneaded heat effect than the time control is more reasonable, but due to the limitations of the measurement means and conditions, the kneading temperature is difficult to accurately measure.

 

3. Energy control method
According to test of optimum kneading energy is as the rubber kneader mixing process of time parameter control. Mixing operation to achieve the specified energy will be the end of the mixing immediately. Rubber and rubber compound mixing process, the rubber kneader shear deformation of rubber is the main factor to determine the effect of mixing and dispersion. Therefore, the kind of essence of the method is to reflect the plastic material reaches the effective shear deformation and the dispersion of the material in the basic stability of the cooling conditions, the energy absorbed by a unit volume of the rubber material kneaded. This control method has the advantage that when the rubber formulations and raw performance does not change, and kneading procedures and equipment is fixed, can guarantee the quality of each batch of plastic material uniformly.
