Plastic film is used in multiple industries including medical and packaging. The film is created using an extrusion process. Static charge is generated almost immediately upon exiting the extrusion head. Cooling of the film generates the initial charge. As the static charge increases dust and contamination in the air are attracted to the film rendering it useless for future fabrication processes. Static charge will be stored within the roll at the end of the extrusion line if it is not neutralized. The stored charge will become obvious as the roll is unwound and affect the next process downstream.Placing a BR2200 static bar prior to the winding stand will prevent the wound film from becoming a battery for the static electricity.Using a pair of Charging Bars and a StaticBond Generator to pin the edges of the newly extruded film to the chill roll helps prevent web wander.
PET is a material used to create bottles and other plastic based parts. PET is also a material prone to static charge. Static electricity is added to PET during the process of converting raw PET into bottles and other parts. The static charge is increased as the newly formed products are conveyed from one process to the next. Conveyors have many points of friction where static is generated. The results is the bottles and parts repelling each other and jumping off the conveyor. At the final destination the parts may be dropped into a bin. The static charge can cause the parts to jump out of the bin or even stick to the conveyer causing jams and lose.Placing a BR4400 Extended Range Static Bar along a section of the conveyor line will neutralize harmful static charges. For optimal results a pair of BR4400 Static Bars should be positioned on opposing sides of the line from each other. This method ensures complete static neutralizing around the entire PET Bottle or part.
Conductors are electrons that are free to move through a specific material, and reach a ground reference. Most common conductors are:
Insulators are electrons that do not have the mobility to flow through the material, and cannot be sent to a ground reference. The only way to neutralize an insulative material is with ionization.
Most common insulators are:
