Scope of application
It is mainly used in the pre-processing of mobile phone case printing, coating, and dispensing in the electronics industry, the surface treatment of mobile phone screens; the surface cleaning of aerospace electrical connectors in the defense industry; and the pre-processing of screen, printing, and transfer printing in the general industry.
The plasma cleaning system has several functions at low temperatures: plasma surface modification, graft polymerization and deposition polymerization. The so-called surface modification refers to changing the activity of the surface or thin layer of the raw material and ion implantation, which is generally called the reduction treatment method. Because the kinetic energy of low-temperature plasma (up to 20ev) is much higher than the chemical bond energy (10ev) in organic chemistry, it is very active. When processing fibrous organic substances, the chemical fibers on the surface of the processed raw materials are easily broken, thereby improving the hydrophilicity, abrasion resistance, pollution resistance and coloring properties of the chemical fibers or textile materials. Plasma technology graft polymerization is used to activate the surface layer, introduce specific active functional groups, and then use the grafting method to connect several specific carbon bonds of the original surface layer to form a new surface layer. Precipitation polymerization refers to the formation of plasma-like organic matter on the surface during the processing process in accordance with the processing technology standard.
In the low temperature plasma cleaning system management system, the electron temperature is only higher than the positive ion and neutron temperature in the low temperature plasma processing system, while the heavy particle temperature is not high, so it is not suitable for some nanocomposite surface layers. Low-temperature plasma treatment will introduce a large number of functional groups on the surface of the polymer raw material. For example, using various non-polymer vapors (O2, H2, Ar) to generate on the surface of the raw material can change the characteristics of the surface of the polymer raw material- OH and other functional groups. When using an external working voltage, it will penetrate the molecular structure of rare gases (N2, O2, CO, etc.), and introduce -OH, -NH2 functional group positive ions and molecules into the surface of the raw material, or directly form oxygen free radicals on the surface of the material. The newly introduced oxygen radicals can also be connected to certain molecular structures on the surface of the raw material through ionic bonds, so that the polymer has new surface characteristics. Plasma surface treatment technology is usually used for surface hydrophobicity, compatibility, activation modification and so on.
Plasma surface treatment machine (also called plasma cleaning machine) uses a low temperature plasma treatment system, which will not cause damage to the product, and low temperature plasma is widely used to change the surface mechanical properties of plastic and metal materials, such as material wear, hardness, and friction , Fatigue, corrosion resistance, etc.
What is a plasma cleaner?
What is a plasma cleaning machine? Is it a plasma cleaning tool? What do you think is a plasma cleaning machine? Some people say that the plasma cleaner is a tool. Does this claim make sense? Next, I will explain it for you.
The ion cleaning machine can process most materials to achieve different processing purposes, including but not limited to making the surface of the material cleaner, easier to bond, and improving printing quality. What kind of plasma cleaner does it belong to? Do you think this is a tool meaningful?
Most plasma cleaners use external energy to generate a strong electromagnetic field around the electrode or in the vacuum chamber under normal pressure or low pressure, which accelerates or collides with the outer electrons of the atoms in the gas to form plasma aggregates. Make the total charges of free electrons, ions, photons, etc. equal, and achieve various technological goals through the electrochemical properties of the plasma.
Plasma cleaners are called "tools", which presumably refer to atmospheric and atmospheric pressure jet plasma cleaners and small vacuum plasma cleaners. The former, due to its simple structure and convenient operation, can be combined with production lines and has been used in many fields. Widely used, it is as convenient to use as “tools” such as wrenches, electric pens, and vise; the latter are mainly used for experimental use in scientific research or institutions, and the volume is relatively small, which can meet the requirements of experimental use. Large-scale vacuum plasma cleaning machines are also used in the production of enterprise products. Therefore, it makes sense to combine the two and call the plasma cleaner a "tool".
