1.The role of plasma cleaning
The principle of plasma cleaning is mainly:
(A) Etching on the surface of the material – physical effect
A large number of active particles in the plasma, such as a large number of ions, excited molecules, and free radicals, act on the surface of the solid sample, which not only removes the original contaminants and impurities, but also produces an etching effect to roughen the surface of the sample and form many fine pits, which increases the specific surface of the sample,improves the wetting properties of solid surfaces.
(B) activation bond energy, cross-linking
The energy of the particles in the plasma is between 0 and 20 eV, and most of the bond energy in the polymer are between 0 and 10 eV. Therefore, after the plasma acts on the solid surface, the original chemical bond on the solid surface can be broken. Free radicals in the plasma form a network of crosslinked structures with these bonds, greatly activating surface activity.
(C) Formation of new functional groups – chemical action
If a reactive gas is introduced into the electric discharge gas, a complicated chemical reaction occurs on the surface of the activated material, and new functional groups such as hydrocarbonyl, amidogen, carboxyl group, and the like are introduced, and these functional groups are all active groups, which can significantly improve the surface activity of the material.
2.Advantages of atmospheric low temperature plasma cleaning
Plasma cleaning is an important material surface modification method and has been widely used in many fields. Compared with some traditional cleaning methods, such as ultrasonic cleaning, UV cleaning, etc., it has the following advantages:
(A) low processing temperature
The processing temperature can be as low as 80℃ and below 50 ℃. Low processing temperatures ensure no thermal effects on the sample surface.
(B) no pollution during the whole process
The plasma cleaner itself is a very environmentally friendly device that does not cause any pollution and does not cause any pollution during the treatment process. It can be combined with the original production line to achieve fully automatic online production, saving labor costs.
(C) stable treatment effect
The treatment effect of plasma cleaning is very uniform and stable, and the conventional sample maintains good effect for a long time after treatment.
(D) It can be perfectly matched with automated assembly lines to increase production efficiency
According to the user’s site requirements, the optimal assembly line production plan is configured to greatly improve production efficiency.
The structure of the plasma cleaning machine is mainly divided into three major components, namely high-voltage excitation power supply, plasma generator spray gun, and control system.
(A) High-voltage excitation power supply:
The generation of plasma requires high-voltage excitation, and the atmospheric low-temperature plasma is excited by an intermediate frequency power supply at a frequency of 10-40 kHz. The high voltage is at 4-10KV. The parameters can be adjusted according to the actual conditions of the sample, and the optimal modification effect has been achieved.
(B) Plasma generator spray gun:
The atmospheric low-temperature plasma generator spray gun can be divided into two types: jet flow direct injection and rotary direct injection, the difference is that the treatment area is different.
(C) Control system:
The control system functions is to control the operation of the entire atmospheric low temperature plasma cleaning equipment and the protection of the overall system.
