SURFACE TREATMENT

As power is supplied to the electrodes, the electric arc only occurs between the points of the electrodes that are closest to each other. A constant flow of air supplied by a blower deflects the arc, causing it to spread and follow the hook-formed curvature of the electrodes. A constant supply of arcs is produced at a rate of 50 to 60 cycles per second.

The ability of the arc to spread depends on the secondary voltage of the transformer, the air velocity generated by the blower, and the geometry (shape) of the electrodes. The higher the voltage and air velocity, the further the arc can be spread. Too much air velocity can break up the arc prematurely, reducing the useful treatment width.

The continuous arc provides a Corona discharge loaded with highly energized ions. This energy field is capable of increasing the wet-ability of the surfaces exposed, providing the necessary cross-linking between polymer surface and inks, coating, or adhesives.

SURFACE TREATMENT

Blown-arc air plasma is formed by blowing atmospheric air past two high-voltage powered electrodes and is sometimes referred to as corona treatment.

The electrical discharge positively charges the ion particles surrounding it. through direct contact, these particles positively charge the treated area of the object’s surface. This makes the surface more receptive to any applied substance such as inks.

Air plasma is a popular surface-treatment technology because it is effective, easy to use, and inexpensive to operate.

SURFACE TREATMENT

Printing – Surface treating parts prior to printing enhances ink adhesion. It makes printing easier, and for others, it makes printing possible.

Painting – Injection molded or thermoformed parts and often treated prior to painting. Surface treatment allows the paint to adhere and also increases the life and durability of the paint on the object’s surface.

Coating – Products are coated to protect their surfaces from harsh environments or as decoration. Doors, frames, and extrusions/profiles are often coated. The medical industry uses surface treating to improve the adhesion of antimicrobial/antibiotic coatings.
