What should I do if the stretch film generates static electricity?
In everyday life, we often see such physical changes. When the hair is gently blown down by the wind, the two iron rods collide with each other, causing electrostatic induction. Have you ever seen stretch film in daily life also form electrostatic induction? Stretch film often forms electrostatic induction during the stretching process, so what are the key factors for electrostatic induction in stretch film? Below is Yu's plastic products stretch film manufacturer, I will introduce you in detail, the main content is as follows:
1. Electrostatic induction occurs in electrostatic induction stress.
Due to the contradiction between particulate matter, melt and mold, as well as the contradiction between the coating and the guide roller of the rewinding machine, the stretch film causes electrostatic induction when it leaves the factory. Stretch film manufacturers recommend that in the process of manufacturing stretch film, an electrostatic agent should be added to remove this electrostatic induction. It should be said that this practical effect is also very good.
2. Electrostatic induction is generated in packaging printing. Composite type. The whole process of laser cutting and making packaging bags.
Due to the contradiction between the stretch film and the guide roller. Due to the contradiction between the high-speed stretch film and the dry gas, the stretch film will form electrostatic induction. Manufacturers of gray and black stretch films remind you that this part of electrostatic induction is very harmful to production and processing. If it cannot be reasonably removed, it will cause great harm to the post-processing process. In general, it is more reasonable to choose a high-temperature superconducting electrostatic induction brush (touch elimination). Based on the carbon brush output with low resistance (1m wide resistance less than 1), touch stretch film is used to solve this problem.
3. Electrostatic induction caused by commodity stretch film on the automatic packaging machine.
The contradiction between the commercial stretch film and the guide roller of mechanical equipment, the electrostatic induction of the stretch film itself has not been eliminated. It is not easy to produce positive outer packaging, and the required content is more sensitive to electrostatic induction, which can be eliminated in the above way. The method is to brush it off with high-temperature superconducting electrostatic induction.
