Causes of static electricity in PE winding tape?

In the process of using PE wrapping tape, static electricity sometimes occurs. In fact, what you need to know is to say that the static electricity phenomenon is not serious or good, and sometimes it is serious and dangerous, so we try our best to prevent this phenomenon. "Then, it is also for better prevention. We will briefly introduce the causes of static electricity so that we can pay attention to it in time in use next time.

When the PE winding tape leaves the factory, static electricity will be generated due to the conflict between the particles, the conflict between the investment heads, and the conflict between the film forming and winding and the guide roller. Therefore, in the production process of PE wrapping tape, it is also recommended to add antistatic agent to eliminate this part of static electricity. It should be said that the effect is still very good. The antistatic agent is a surfactant containing a polar hydrophilic group and a non-polar lipophilic group. Another important point is that lipophilic groups have some compatibility with plastics. Hydrophilic groups can ionize or adsorb water in the air, forming a very thin conductive layer on the surface to avoid leakage of charge and eliminate static electricity. Static electricity in printing, restructuring, cutting and bag-making processes. The thermal problem is mainly due to the conflict between the PE wrapping belt and the guide roller, and the conflict between the high-speed moving film and the dry air. It has static electricity. Therefore, you need to understand that this part of static electricity has a great impact on production. If the static electricity cannot be effectively eliminated, it will also have a great impact on the post-processing process. In general, it is more useful to use PE wrapped with superconducting electrostatic brushes (touch-type elimination). When heat is present in the form of a contact film, static electricity generated by brushes with extremely low resistance (less than 1 resistance across 1 meter) can solve this problem.

The ionizer can also be used to blow the generated ions onto the membrane by wind (non-contact). However, in practice, when the ionized gas eliminates static electricity, one will find that working together will also cause some air to flow back. The products we are discussing today may conflict with the guide rollers of the equipment. PE wrapping tape itself cannot completely eliminate static electricity. The formation of active packages is difficult and the contents need to be sensitive to static electricity. At this time, the above method can also be used to eliminate static electricity. Another useful method is to use superconducting electrostatic brushes to eliminate them. Therefore, it is natural to display static electricity in different parts during use. The causes are different and the treatment is different. Then, according to different situations, when dealing with this issue, we must make a decision based on our own actual situation.

The above is about the cause of static electricity in the PE wrapping tape. As long as you pay attention to its correct use method in the daily use process, you can play its role. You must pay attention to the correct use method during the operation to avoid occurrence. Unnecessary trouble.
