How to solve the problem of uneven dispersion of black masterbatch? I believe many factories and enterprises have also encountered such a situation: the dispersion of black masterbatch is uneven. What to do in this situation? Jinhui Xiaobian can help you solve the problem.
1. Connect the broken screw and change the diameter of the front section slightly smaller than that of the back. The gap is large and easy to feed.
2. Replace the disc of the motor. Increase the diameter of the rotating disc, so that the screw speed is faster. In disguise, it is stirred in before the material is dissolved. The disadvantage is that the screw is broken carefully. When the speed is fast, the temperature should be increased in the rear heating area, otherwise the carrying force of the screw is too large.
3. Reduce the temperature of the feed port, or even very low, such as 100 degrees, in this case. The material is not melted first, but directly squeezed in, relying on the power of the screw rather than heat. The disadvantage of this is that if the material is made for a long time, the damage to the screw is relatively large.
4. If the material is dried, it will melt at the mouth of the material first, but the melting is not complete, so it will be squeezed there. The dried material is easier to get in than the wet material.
5. Increase the feeding port. If you do this for a long time, you can cut the feeding port larger. Of course, large light cutting does not mean that more materials can be fed. Mixing equipment can be installed. Refer to the production equipment of PS foam powder.
