Treatment Equipment
1. Product Introduction
The atmospheric plasma cleaning machine is composed of plasma
generator, gas conveying system and plasma spray gun.Atmospheric
plasma cleaning machine depends on electric energy, produce high
voltage, high frequency energy.These energies generate low
temperature plasma in the activated and controlled glow discharge
in the nozzle steel tube, and the plasma is sprayed to the treated
surface with the help of the compression space, resulting in the
corresponding physical and chemical changes on the treated
surface.The surface of the treated object is cleaned, oil,
additives and other ingredients are removed, and surface static
electricity is eliminated.At the same time, the surface has been
activated, increased adhesion, is conducive to the product bonding,
spraying, printing and sealing.
2. Characteristics

5. Principle of Plasma Cleaning
Plasma is a kind of existing state of substance. It is usually
juxtaposed with the solid, liquid and gaseous states of a substance
and is called the "fourth state of matter". It can use the plasma
high-energy particles and the material surface physical and
chemical reaction to realize the material surface activation,
etching, decontamination and other processes, as well as the
material friction coefficient, adhesion and hydrophilic and other
surface properties of the purpose of improvement.
- Cleaning Effect of Plasma:
The surface of the treated material is cleaned chemically and
physically by making the plasma and material surface contact and
react using plasma cleaning technology (low temperature plasma
characteristics) in order to improve surface smoothness, implant
new chemical functional group and realize etching.
(1) Cleaning and activation for material surface
(2) Form new functional group- Chemical effect.
If reactant gas is introduced into electricity-discharged gas,
complex chemical reaction will happen to the surface of activated
material. New functional groups will be introduced, such as
hydrocarbyl, amidogen and carboxyl, all of which are active groups
and could improve the activity of material surface significantly.
(3) Plasma etching.
Plasma etching means a process of removing volatile gaseous
substance generated by creating plasma of a kind of proper gas
chosen and substance on solid surface.
Plasma etching technique is actually a kind of reactive plasma
process. The so-called direct plasma, also called reactive ion
etching, is a kind of form under which plasma is etched directly.
Its main advantages include high etching rate and evenness. The
technological parameters of plasma play a vital role in etching
effect.

7. Plasma Cleaning Advantages:
- It replaces the traditional wet cleaning technology, and is green
and environmentally friendly (containing no VOC).
- Gas serves as reaction medium so operation cost is low (oxygen).
- Broad range of application; treatment object and base material
needn’t to be distinguished (material diagram).
- High cleaning efficiency and easy to realize automation.
- Improve material surface performance and adhesive force while
removing dirt.
8. Comparison Before and After Plasma Treatment:
The contact Angle of liquid on the surface of solid material is an
important parameter to measure the wettability of liquid on the
surface of material.If θ<90°,the solid surface is hydrophilic,
and the smaller the Angle, the better the wettability; if θ>90°,
the solid surface is hydrophobic.
The measurement of the dyne value is very common in printing,
coating, laminating, welding and other applications. It can reflect
the ability of the material surface to bond easily. In general, the
greater the dyne value, the better the bonding performance of the
surface with another material.
9. Common Applications:
Surface modification of polymer materials Improves surface bonding
property
Removal of oxide residue of electronic components, improve the bond
quality and enhance the bonding effect.
Glass substrates remove organic contaminants
