What other applications of plasma technology besides TV,cutting

What other applications of plasma technology besides TV,cutting

A Plasma Display Panel, or Plasma Display Panel in Chinese, is a device that infuses a mixture of gases between two ultrathin glass panels and applies a voltage that USES fluorescent light to produce images. Compared with CRT display, it has the characteristics of high resolution, large screen, ultra-thin, rich and bright color. Compared with LCD, it has the characteristics of high brightness, high contrast, large viewing Angle, bright color and rich interface. Plasma cutting is a process in which the heat of high temperature plasma arc is used to partially melt (and vaporize) the metal at the cut of the workpiece, and the molten metal is expelled by the momentum of high speed plasma to form the cut. Plasma arc welding is a fusion welding method using plasma arc high energy density beam as welding heat source. Plasma arc welding has the characteristics of concentrated energy, high productivity, fast welding speed, small stress deformation, stable electricity and suitable for welding thin plate and box materials, especially suitable for all kinds of refractory, easily oxidized and heat-sensitive metal materials (such as tungsten, molybdenum, copper, nickel, titanium, etc.) welding. In fact, these are just a few of the applications of plasma. Plasma has been widely used in IC semiconductor industry, LCD industry, semiconductor industry, photoelectric industry, photovoltaic industry, electrical manufacturing industry, automobile manufacturing industry, bio-pharmaceutical industry, new energy industry, battery industry and many other industries. Plasma has the advantages of energy saving, environmental protection, high efficiency, wide applicability, strong functionality, favored by all industries. Plasma is widely used in many industries. Here are some examples for reference: (1) Low-pressure high-density plasma was used for plasma etching; (2) Manufacturing of solar thin-film cells; (3) Manufacturing and cleaning of LCD, LED, OLED and other display equipment; (4) Chip bonding pretreatment; (5) Removal of metal oxides and high-precision metal purification; (6) Bonding of electrical connectors; (7)Plasma surface treatment and modification of materials; (8) Plasma polymerization medium film and magnetron sputtering vacuum coating; (9) Disinfection, biological and medical fields, including seed treatment, human tissue (wound) treatment; (10) Automobile sensor treatment, sewage treatment, tail gas treatment and so on.

The application effect of plasma processing technology on the housing

The application effect of plasma processing technology on the housing

Mobile phone is one of the indispensable tools in people's life. It is a headache that after a period of time, you will find that the shell of the phone will lose paint, wear, or the logo will become more and more blurred, seriously affecting the appearance of the phone. And the application of plasma surface treatment technology, to help mobile phone manufacturers to solve the above problems. Plasma technology can be said to be a new environmental technology in the market, instead of the traditional chemical treatment of mobile phone shell surface. The shell of the mobile phone treated by the plasma surface equipment has more wear resistance, which can ensure that the paint will not fall off or grind after a long time of use. Because the plasma surface treatment technology can clean the dust impurities or oil stains left by the mobile phone shell during production, a larger program can improve the activity of the plastic surface, so that the coating effect is very uniform, the coating adhesion effect is better, and the connection between the coating is stronger. Now almost all mobile phone cases will be glued or printed with the brand LOGO or decorative strips, which can make the appearance of the phone more sophisticated. The previous mobile phone shell is composed of ABS, its surface tension is high, generally do not need to deal with. But as PC, nylon, fiberglass and other materials are widely used, the surface tension of the substrate cannot be increased to the required value of glue. The surface tension of the materials to be bonded can be increased to the required value of the glue by the high efficiency of the low-temperature plasma. Plasma treatment can improve the adhesion of plastic surface, remove organic pollutants, interpose polar organic functional groups on the surface, improve surface hydrophilicity and surface wettability. A clean surface and surface wettability are critical to a strong bond between two surfaces. And with the development of plasma technology, as well as the emergence of many companies such as Sing Fung Intelligent Manufacturing specializing in the production of plasma processing equipment, plasma technology has been widely used in the mobile phone industry.

Difference advantage between dry plasma cleaning and wet cleaning

Difference advantage between dry plasma cleaning and wet cleaning

CRF plasma cleaning is the use of working gas under the action of electromagnetic fields to excite the plasma and the surface of the object to produce physical and chemical reactions, so as to achieve the purpose of cleaning. Wet cleaning is the use of chemical solvent or water in a certain period of time to clean the object, in order to achieve the purpose of cleaning. Plasma cleaning is the use of different gases for object treatment cleaning, no waste, its gas can be directly discharged into the atmosphere through the vacuum system and neutralizer after treatment, health, environmental protection, benefit, safety. Compared with plasma cleaning, wet cleaning tends to produce a large amount of waste and chemical gas, which is not conducive to health and environmental safety. Recently, the customer mentioned that the use of plasma cleaning equipment caused sputtering damage on the material surface. In fact, as long as the energy control is appropriate, mild surface damage can enhance the adhesion of the workpiece itself. In some cases, plasma cleaning treatment becomes an indispensable process. For example, Ar plasma is used to remove surface oxides of some materials. Of course, some process tests have shown that this kind of damage can be minimized by using a step-by-step process for cleaning. In addition, we believe that wet cleaning will be more harmful to materials beyond control, and plasma cleaning treatment is more worthy of application. In addition, the toxicity of plasma cleaning residues has been studied deeply at home and abroad. With its advantages in health, environmental protection, benefit and safety, the plasma cleaning equipment and process gradually replace the wet cleaning process, especially in the precision parts cleaning and new semiconductor materials research and integrated circuit device manufacturing industry, the plasma cleaning application prospect is broad.

How the plasma processor works

How the plasma processor works

The principle of plasma processor is to improve the hydrophilicity, adhesiveness, coldability, biocompatibility and electrical properties of materials by low temperature plasma surface treatment, resulting in a variety of physical and chemical changes on the surface of materials, such as etched and rough, formation of dense cross-linking layer, or introduction of polar groups containing oxygen. The surface treatment of silicone rubber by plasma showed that N2, Ar, O2, CH4-O2 and AR-CH4-O2 plasmas could all improve the hydrophilicity of silicone rubber, among which CH4-O2 and AR-CH4-O2 had better effects and did not degrade with time. Low temperature plasma is used to treat PE, PP, PVF2, LDPE and other materials under appropriate technological conditions. The surface morphology of the materials changes significantly, and a variety of oxygen-containing groups are introduced to change the surface from non-polar and difficult viscosity to certain polarity, easy viscosity and hydrophilic, which is conducive to bonding, coating and printing.
