　　Seismograph plasma surface treatment system mainly includes three parts: full-bridge digital circuit plasma power supply, plasma spray gun and intelligent control system.
 

　　1. The role of plasma cleaning
 

　　The principle of plasma cleaning is mainly:
 

　　(1) Etching effect on the surface of the material-physical effect
 

　　A large number of active particles in the plasma, such as 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 etching and roughens the surface of the sample. , Forming many tiny potholes, increasing the surface of the sample. Improve the wettability of solid surfaces
.

　　(2) Activation bond energy, cross-linking effect
 

　　The particle energy in the plasma is 0-20eV, and most of the bond energies in the polymer are 0-10eV. Therefore, after the plasma acts on the solid surface, the original chemical bonds on the solid surface can be broken. Free radicals and these bonds form a network-like cross-linked structure, which greatly activates the surface activity.
 

　　(3) Form a new functional group-chemical action
 

　　If a reactive gas is introduced into the discharge gas, a complex chemical reaction will occur on the surface of the activated material, introducing new functional groups, such as hydrocarbon groups, amino groups, and carboxyl groups. These functional groups are all active groups and can significantly improve the surface activity of the material.
 

　　Advantages of atmospheric low temperature plasma cleaning
 

　　As an important material surface modification method, plasma cleaning 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:
 

　　(1) Low processing temperature
 

　　The processing temperature can be as low as 80°C and below 50°C, and the low processing temperature can ensure that there is no thermal effect on the surface of the sample.
 

　　(2) No pollution in the whole process
 

　　The plasma cleaning machine itself is a very environmentally friendly equipment, which does not produce any pollution, and the treatment process does not produce any pollution.
 

　　It can be matched with the original production line to realize fully automatic online production and save labor costs.
 

　　(3) Stable treatment effect
 

　　The treatment effect of plasma cleaning is very uniform and stable, and the effect is maintained for a long time after conventional sample treatment.
 

　　(4) It can be perfectly matched with automated assembly lines to improve production efficiency

　　Accord
ing to the user's on-site requirements, the optimal assembly line production plan is configured, which greatly improves the production efficiency.
