Static electricity is a natural phenomenon that everyone has encountered in life, such as the spark that occurs when sweaters are taken off in winter. Static electricity is harmful in many situations. For example, there should be no static electricity in the production of precision parts. The following are the main reasons for the static electricity generated by the stretched film.
Static electricity generated during production.
Because the particles rub against each other, the friction between the melt and the die, the film is wound and the friction of the guide roller, resulting in static electricity generated at the time of shipment. Black stretch film manufacturers reminded that antistatic agents should be added during the production of stretch film to eliminate this part of static electricity. It should be said that this effect is still very good.
Static electricity generated during printing, compounding, slitting, and bag making
The stretched film generates static electricity due to friction between the stretched film and the guide roller, friction of the stretched film running at a high speed, and dry air. Black stretch film manufacturers suggest that this part of the static electricity has the greatest impact on production, and if it can not be effectively eliminated, it will have a great impact on the post-processing process. In general, the use of superconducting electrostatic brush (contact elimination) is more effective, it is in contact with the stretch film, the generated static electricity through the low resistance (1m wide resistance is less than 1) brush grounding Export to solve this problem.
Static electricity generated by the finished stretch film on the automatic packaging machine
The friction between the finished stretch film and the equipment guide roller, and the stretched film itself are not completely eliminated by static electricity. The automatic packaging is difficult and the required contents are sensitive to static electricity. In this case, the above method can also be used to eliminate static electricity. The most effective way is to eliminate it by using a superconducting electrostatic brush.
