corona rubber covered roller

  Corona roller is a special roller whose characteristics and application are mainly related to corona treatment technology. Corona roller cover layer using imported silicone rubber as insulation layer, hardness of 70-80A, ozone resistance, by 200000 volts high pressure testing to ensure that the substrate surface has higher adhesion and roughness. It applies high frequency and high voltage to the equipment to produce high frequency and high voltage discharge, forming small dense purple blue sparks. This treatment method can ionize the air, produce a variety of electric ions under the action of a strong electric field to accelerate and impact the plastic film in the treatment device, but also can provide all the characteristics of plastic film corona treatment to meet, easy to repair after breakdown, especially small damage can be repaired on-site to ensure the minimum downtime. Sharp objects or knife damage caused by careless operation is very fragile, and special care should be…
