How is corona treatment measured?
Wetting is the ratio between the surface energies of the liquid and the plastic material, and is measured in dyne/cm. Corona treatment ensures the surface energy of the plastic is higher than that of the liquid by increasing the adhesion of the plastic surface.
What is plasma surface treatment?
Plasma surface treatment is a process that raises the surface energy of many materials so as to improve the bonding characteristics. One form of plasma treatment is also commonly known as a corona treatment, which was invented by Danish engineer Verner Eisby in the 1950s.
What color is oxygen plasma?
light blue colorDifferent gases give different colors. For example, oxygen plasma emits a light blue color. A plasma's activated species include atoms, molecules, ions, electrons, free radicals, metastables, and photons in the short wave ultraviolet (vacuum UV, or VUV for short) range.
Is oxygen a plasma?
Oxygen(O2) is the most common gas used in plasma cleaning technology due to its low cost and wide availability. Oxygen plasma is created by utilizing an oxygen source on a plasma system.
