What is surface treatment?
Simply put, a surface treatment is a process applied to the surface of a material to make it better in some way. This could be from a performance perspective, such as improving adhesion and surface wetting characteristics.
What is surface energy?
Surface energy is the energy of a material available at it’s surface to interact with the world around it. A low surface energy means the surface prefers to be itself and not react, whereas a high surface energy will pull liquids closer, interacting strongly.
Surface treatment for plastics
The surface energy of many plastics, such as polyethylene and polypropylene, is actually insufficient for bonding or printing.
How long do surface treatments last?
The shelf life of pre-treated materials is dependent on a number of factors, including the type of plastic, it’s formulation and how it was treated. It even depends on whether it was exposed to elevated temperatures following treatment. As a result, shelf life can range from just a couple of hours to even a few years!
Surface Wettability
Figure 1 to your right helps illustrate the difference between good and poor wettability.
Surface Energy Solid Materials
Figure 2 to your right shows absolute values of surface energy for solid materials and the surface tension of many plastics including polyethylene and polypropylene is often insufficient for bonding or printing.
Basics of high voltage discharge in air and its application to surface treatment
In the presence of a high voltage discharge in an air gap, free electrons, which are always present in the air, accelerate and ionise the gas. When the electric discharge is very strong, collisions of high velocity electrons with molecules of gas result in no loss in momentum, and electron avalanching occurs.
Shelf life of treated surfaces
The shelf life of pre-treated materials ranges from hours to years, depending on the plastic, its formulation, how it was treated and its exposure to elevated temperature after treatment.
Applications of Tantec Electrical Surface Treatment Technology ( EST)
The following materials have been successfully treated using EST technology:
General introduction
A traditional surface treatment technique, shot peening (SP), has been effectively and widely applied in industry for over six decades. In an SP process, metal or ceramic balls acting as a minuscule ball-peen hammers make a small indentation or dimple on the metal surface on impact.
