Introduction to low temperature plasma surface treatment technology
The energy of particles in low temperature plasma is generally about several to ten electron volts, which is larger than the bond energy of polymer materials (several to ten electron volts), and it can completely break the chemical bonds of organic macromolecules and form new bonds. However, it is much lower than high-energy radioactive rays and only involves the surface of the material without affecting the properties of the matrix. In low-temperature plasma in non-thermodynamic equilibrium state, electrons have high energy, which can break the chemical bonds of molecules on the surface of materials and improve the chemical reactivity of particles (greater than that of hot plasma), while the temperature of neutral particles is close to room temperature. These advantages provide suitable conditions for surface modification of heat-sensitive polymer polymers. Through low temperature plasma surface treatment, a variety of physical and chemical changes occur on the surface of the material, or produce turbidity-etching and rough or form a dense cross-linked layer, or introduce polar groups containing oxygen, so that the hydrophilicity, cohesiveness, chromability, biocompatibility and electrical properties are improved. When the material surface is treated under the appropriate technological conditions, the surface morphology of the material changes significantly. A variety of oxygen-containing groups are introduced to make the surface change from non-polar, difficult viscosity to a certain polarity, easy viscosity and hydrophilicity, which is conducive to bonding coating and printing. The air between the two electrodes generates gas glow discharge by applying AC high frequency and high voltage to the two electrodes. The electrons constantly collide with the gas molecules and produce a large number of new electrons. When these electrons reach the anode, they gather on the surface of the medium and modify the surface

Aviation industry
Plasma cleaning applications
With the development of the aviation industry, manufacturers are looking for products with longer life spans, more reliable quality and lower costs. In the past, the coating and stripping strips on aircraft were made of aluminum alloy, but now, these parts are mainly made of carbon fiber reinforced plastics. Plasmas play a big role in this. Carbon fiber reinforced plastic surface stability is better, so that the bonding and spraying process presented a more perfect state

Metal industry
Whether it is from the metal ornaments in our clothes or the metal tables and chairs used in our homes, the surface may be treated by plasma. Nowadays, people have higher and higher taste for the design of products. Manufacturers in order to meet the needs of consumers will produce a variety of beautiful and durable metal products to attract the market, it can be said that plasma surface treatment of materials has infiltrated into our lives, in the past 30 years, low temperature plasma is widely used to change the mechanical properties of the surface of metal materials, plasma surface treatment of metal is :
1. The friction and corrosion resistance of iron and steel alloys were improved by ion beam nitriding
Metal industry
2. Ions injected into the metal surface can form metal solid solution and sediment, so it can improve the hardness and wear of metal materials

Medical industry
Medical materials refer to inanimate materials used in contact with biological tissues to form functions. They are very good auxiliary materials in medical treatment, including polymer materials, metals, ceramics, glass or composite of various materials, etc., which are widely used in artificial organs, surgical repair, dental materials, cladding materials, orthopedic devices and medicine. Functional and mechanical properties, these materials are very good, but good biocompatibility is also quite critical, using plasma surface modification method can make them good compatibility, plasma only on the surface of a thin layer of treatment, does not change the performance of the material, and sterilization effect. So plasma surface treatment is becoming more and more widely used in medical materials.

Household appliance industry
The surface coating, spraying and bonding process of daily necessities and household appliances, plasma pretreatment to improve the quality of bonding and coating

Plastic industry
Plastic, rubber, metal and other pretreatment before bonding, improve the surface adhesion, mobile phones, computers, toys and other plastic shell spray pretreatment, improve the surface adhesion

Packaging industry
In the field of printing and packaging applications, perhaps in the previous plasma surface treatment is not much known to the public, in fact, we began to use the corona discharge, flame treatment surface modification method, which is the most common form of discharge in the ion – mass barrier discharge (DBD) but now low temperature plasma processor has been widely used in the packaging industry, Change the printability of the packaging surface and the adhesion of the composite surface, plasma processing function for UV, coating, glazing, polymer and other materials surface treatment; Professional improve coated paper, glazed paper polishing, gold and silver card, aluminum coated paper UV, OPP, PP, PET and other color boxes, color box surface paste box fastness; Eliminate all kinds of packaging box opening problem. Improve work efficiency, reduce grinding pollution, eliminate paper powder pollution of box paste machine, save consumables, save glue cost.
