Xiangsheng take you to understand the dispersion method and skills of cutting carbon fiber!

In modern industrial production, the application of new materials is more and more extensive, among which the short-cut carbon fiber has excellent performance and wide application prospects. However, because of its strong adhesion and easy aggregation, how to disperse correctly is the key to affect its performance.

So, how does the chopped carbon fiber disperse? First, the cut carbon fiber needs to be pre-treated before dispersing. Heating treatment can reduce its surface energy, thus reducing its adhesion, while also improving its dispersion.

Short carbon fiber dispersion tips:

1. Ultrasonic dispersion method

The mechanical vibration of high frequency ultrasonic wave can make the short carbon fiber in the dispersion system shake and disperse evenly. Ultrasonic dispersion method is a fast and efficient dispersion method without thermal damage to the material.

2. Heat dispersion method

The short-cut carbon fiber is added to the high-temperature solvent and cooled quickly after heating. In the process of rapid cooling, the short-cut carbon fiber can be fully dispersed in the solvent, and the dispersion effect is relatively good.

3. Magnetic dispersion method

Magnetic particles are added to the dispersion solvent, and the short-cut carbon fiber is dispersed in the liquid through the action of external magnetic field. This method has a good dispersion effect and can be continuously produced.

The choice of short carbon fiber dispersion technique should be judged according to the actual situation and product characteristics. The three methods introduced in this paper can effectively solve the problem of dispersion of short-cut carbon fiber. For different users, magnetic dispersion method, ultrasonic dispersion method and heating dispersion method three methods have their advantages and disadvantages. Different dispersion methods should be selected according to the actual situation.
