Application of low-temperature plasma surface treatment technology on plasma aluminized base film:
As a new surface treatment technology, low temperature plasma surface treatment technology has unique advantages. Low temperature plasma technology adopts gas reaction, the whole process is liquid free and the reaction is fast. It has the advantages of high efficiency, energy saving and environmental protection. Low temperature plasma technology is widely used in a variety of applications, from the microelectronics industry to the manufacture of integrated circuits, to the treatment of a variety of polymer films, and a wide range of toxic waste treatment applications.
Low temperature plasma treatment technology applied to aluminum-based films:
The purpose of the aluminized substrate film pretreatment is to improve the adhesion of the aluminized layer, improve the barrier effect of the aluminized layer (such as blocking gas, light, etc.), and improve the uniformity of the aluminized layer. In the plasma pretreatment process, the surface cleaning and activation of the substrate membrane is chemically modified to make it more firmly bound to aluminum metal atoms.
Mobile film roll of polymer membrane plasma processing, can remove dirt from polymer surface, and can easily open the chemical bonds of the polymer surface, making it a free radicals, and with the free radicals, atoms and ions in the plasma reaction produces new functional groups, such as hydroxyl (hydrogen) (OH), cyano (CN), carbonyl (- C = O), carboxyl (-cooh) group or amino (NH3), etc. These chemical groups are key to enhancing adhesion. Carbonyl groups play a key role in adhesion to the aluminum layer by improving the adhesion between polymer surfaces and other materials deposited on these surfaces. These functional groups improve wettability.
Of course, low-temperature plasma surface treatment technology is an effective way to improve the surface properties and functions of various plastic films. After the film surface can be treated, there will be a great improvement, so it will improve the wettability and binding force of these films. Especially for PTFE film, the treatment effect can not be achieved by other treatment methods. Plasma surface treatment technology is a safe and environmentally friendly way.
