Commonly known as the electric airsick corona processor in the packaging industry, electronic impact machine, edm machine. Technically known as dielectric barrier discharge. Class is mainly used in plastic film or plastic products surface treatment, as for the above material for ink printing, composite, blown film, coating, adhesive and material modification, grafting, polymer, coating, stretch film, paste processing before, in order to make the product surface has a stronger adhesive force (that is, the higher dyn coefficient), to prevent the raw materials in the process of production appeared to jilt color prinrt function,soft start function,memorizing function,work frequency automatic trackingting, composite paste is not strong, the phenomenon such as uneven coating glue leakage, affect the product quality, must first shock corona treatment.
