How to remove static electricity from slitter equipment in film industry?
During the film production process, due to the existence of a large number of idlers, rubber rollers and metal rollers, a large amount of friction of the insulating film material will cause high static electricity up to 100,000 volts, which will seriously affect product quality, production efficiency and production safety. In high-speed applications such as slitting, slitting, coating, and rewinding, static electricity must be effectively eliminated.
General solution for thin film static elimination:
1. Adjust the ambient humidity appropriately.
2. Do a good job of grounding.
3. Staff wear anti-static gloves, shoe covers and work clothes.
4. Use static eliminator: The static eliminator can generate positive and negative ions to neutralize the positive and negative charges on the surface of the plastic and plastic. One-time investment is one of the widely used methods.
Shanghai Anping Statics recommends using an ion bar to remove static electricity. The surface of the film is flat and most of the film processing is automated production. The appearance of the ion rod is small and beautiful, and the static electricity removal effect is large and rapid. It is especially suitable for large, medium and small mechanical equipment and easy installation. It is not necessary to fix the ion wind rod above the surface of the film, and it needs to be 2-10CM away from the film. The film passes the ion wind rod. Anping's ion bar can neutralize the film surface statically in about 0.2 seconds.
Next, let's take a look at the static problems in the slitter equipment in the film industry and the installation and application of static eliminators.
1. It is necessary to remove static electricity at the winding place after film production (casting, drawing, etc.). Because in the process of rapid unwinding, a large amount of friction, peeling, and squeezing will occur between the material and the roller, which will cause the surface area of the object to accumulate different electrostatic charges, and the electrostatic value will continue to accumulate with the increase of speed and duration, causing Very serious static problem.
Case 1:
2. During the cutting process, static electricity must be removed. If static electricity is not removed, the processed products will be defective. For example: Excessive static electricity causes problems such as adsorption during the production process of downstream customers and excessive static electricity on the film surface during the slitting process.
Case 2:
