What is Corona treatment?

Corona treatment is a process where the surface of the item changes by exposing plasma. The coronal plasma field, made of hundreds or thousands or small plasma points, exposes the surface of the material a special low -temperature plasma. This exposure changes the properties of the material, usually lend properties that have not been present before. Corona treatment is a safe and low -cost method of treatment of material surfaces and is used by hundreds of ways. One of the most common uses of coronal treatment is the preparation of non -porous surfaces for printing or adhesion.

Plasma is the condition of the mass that occurs when the gas is exposed to an electric current. The gas structure begins to decompose into its particles. This disintegration causes gases to show the properties they haven't had before, and often lead to excess energy to be bleeding into plasma. This energy bleeding is usually warm or light and a responder from florescent lights and neon brands. This electrode will charge the gas around it and create a small koUli plasma. This plasma naturally moves away from the electrode until it is far enough to remember normal gas. As plasma moves, it creates a convection that attracts the unchanged air closer to the electrode. This converts new gas into plasma, so the Corona area is constant.

In order to use this plasma to treat corona, manufacturers use coronal drain fields. It is an area covered with electrodes, so when it is on, Coronas overlaps and creates a solid plasma area. This is often set so that objects can move through the corona plasma curtain on the transport belt.

Because corona treatment uses plasma forms that exist only higher than room temperature, can be used on many different materials. Everything from paper to plastic to metal can undergo coronal treatment. When an item is first produced, it is often exposed to coronal plasma but the structure withIt often slowly moves back to the original composition, so another exposure is sometimes required.

The most common mass use of coronal treatment is plastic of sheet metal. Because plastics such as polypropylene are both chemically inert and non -porous, printing inks, adhesives and other common substances do not have a way to stick to them. Over time, substances simply slip. Using corona treatment, the surfaces of these plastics change to accept certain types of common chemical bonds.
