The application of plasma surface treatment technology in the automotive industry to solve the problem of bonding

The application of plasma surface treatment technology in the automotive industry to solve the problem of bonding

Because most of the plastic surface tension is very low, so in the past a lot of design is to use accommodation material, as long as the surface after a certain plasma surface processor processing, can achieve spraying or bonding and other technical requirements, priority to use this material. In recent years, the cost and performance of materials have become increasingly dominant factors in product design, which has led auto industry manufacturers to focus on more plastic varieties. Nowadays, PP, PC, ABS, SMC, various elastomers and various composite materials have been widely used in the field of automotive manufacturing. In this way, it not only solves the mutual bonding between the parts of the same material, but also solves the mutual bonding between the parts of different materials, but the traditional processing method is difficult to meet the requirements of this processing technology. From the surface treatment effect, the current various surface treatment methods, fluorination treatment effect is good, can make the material to enhance the adhesion. But this method produces a lot of harmful fumes, and the cost of treating them is unacceptable to most carmakers. Happily, the emergence of plasma surface treatment technology has brought a revolution to the plastics industry, which has the following advantages: 1, environmental protection technology: the action process of plasma surface treatment is gas-solid coherent reaction, does not consume water resources, no need to add chemical agents. 2, high efficiency: the whole process can be completed in a relatively short time. 3, low cost: simple equipment, convenient operation and maintenance, with a small amount of gas instead of expensive cleaning fluid, but also without treatment of waste liquid. 4, can go deep into small holes and depression area, to complete the cleaning task. 5, plasma surface treatment machine for a wide range of application: plasma surface treatment technology can achieve the treatment of most solid substances, so the application range is very wide.

6 surface treatment plasma cleaning machine solution application

6 surface treatment plasma cleaning machine solution application

In view of the wide application of plasma cleaning machine in all walks of life, CRF Chengfeng Intelligent manufacturing Xiaobian summed up the six application solutions of plasma cleaning machine. 1. Surface Activation Solution: After the plasma surface treatment of the object, can enhance the surface energy, hydrophilicity, increase the bond, adhesion and so on. 2, the material surface etching solution: The material surface is selectively etched by reactive gas plasma cleaning. The impurity residues on the etched material are converted into gaseous state, and then discharged by vacuum pump. After treatment, the micro surface volume of the material increases, and it has good hydrophilicity. 3. Nano coating solution: After plasma cleaning machine treatment, plasma guided polymerization reaction to form nano coating. Through the surface coating can make a variety of materials to achieve hydrophobic (hydrophobic), hydrophilic (hydrophilic), lipphobic (fat resistance), oleophobic (oil resistance). 4. TSP/OLED product solutions: TSP: the main process of touch screen cleaning, improve OCA/OCR, laminating, ACF, Ar /AF coating adhesion/coating force, through a variety of atmospheric pressure plasma form, can eliminate bubbles/foreign bodies, all kinds of glass, film uniform plasma discharge, so that the surface without damage processing. 5, vacuum plasma spraying equipment solutions: Because of the high energy density in the plasma of the vacuum plasma cleaner, virtually all powders with a stable molten phase can be converted into a dense, strongly adhered spray coating. The quality of the spray coating depends on the instantaneous melting degree of the spray powder particles when they hit the surface of the workpiece. Vacuum plasma spraying technology has improved the production efficiency of modern coating machines. 6, cleaning the surface solution: The high-energy disordered plasma is generated in the vacuum plasma cavity by the radio frequency power supply, and the surface of the product to be cleaned is bombarded by the plasma to make the pollutants fall off from the product to achieve the purpose of cleaning.

What gas is used for plasma surface treatment to remove surface residues and dirt

What gas is used for plasma surface treatment to remove surface residues and dirt

Plasma surface treatment machine in the cleaning process with different gases, the cleaning residual dirt effect is also very different. One of the commonly used gases is the inert gas argon (AR), which can effectively remove nanoscale surface pollutants in the cleaning process of vacuum equipment. If you want to strengthen the etching effect, you can pass oxygen (O2), can effectively remove organic pollutants, such as photoresist, etc. Some hydrogen (H2) can be used in combination with other oxides that are more difficult to remove. A mixture of hydrogen and nitrogen gas (95% nitrogen and 5% hydrogen) is usually chosen. The widely used gas is nitrogen (N2), which is cheap to produce. The gas is mainly used for surface activation modification of materials in combination with on-line plasma surface treatment technology. It can also be used in a vacuum. Nitrogen (N2) is a good gas to improve the surface wetting property of materials. In addition, there are also carbon tetrafluoride (CF4), sulfur hexafluoride (SF6) and other similar special gases, plasma surface treatment machine using these gases on the etching and removal of organic matter is more significant. But the premise of the use of these gases is that they must have a good anti-corrosion gas path structure, and they must wear protective cover and gloves to work normally, although there will be no danger but protection or do enough.

The use process will not cause any harm to the operator's body; As far as the processing mode of plasma surface processor is concerned, its cost is low, and it has objective cost performance and advantages. From the point of view of environmental protection, the whole process of plasma surface processor cleaning equipment is pollution-free, pollution-free, green environmental protection. The plasma surface treatment machine can keep the operator away from the harm of harmful solvents to human body, and also avoid the problem that the object is easily damaged when wet cleaning. Avoid the use of ODS harmful solvents, so that after washing will not produce harmful pollutants, so it belongs to the green cleaning method of environmental protection, under the global environmental protection of great attention, its importance is increasingly prominent. After the plasma surface processor cleaning equipment cleaning, the cleaned object is dry, no need to go through air drying or drying treatment can be sent to the next process, can improve the processing efficiency of the entire process line. Plasmas produced using high frequencies are different from direct light such as lasers. The direction of motion of the plasma is scattered, which allows it to penetrate into tiny holes and depressions in the interior of an object to perform various cleaning tasks, so the shape of the object being cleaned does not need to be considered too much. In addition, for these difficult to clean parts, its cleaning effect is similar to or better than freon cleaning. Processor therefore plasma surface cleaning equipment in the application of high and new technology industry is very broad, especially in the automotive, semiconductor, microelectronics, integrated circuits, electronics and other industries, the application of vacuum plasma surface treatment machine is a kind of important equipment, is also a component indispensable to the production process, is the key to improve the quality of products.

PTFE plasma cleaning machine processing to improve the material surface bonding ability

PTFE plasma cleaning machine processing to improve the material surface bonding ability

1. Plasma cleaning machine low temperature plasma etching: During the entire process of low temperature plasma etching, the etched object changes into the gas phase. Using a mechanical pump to drain the excess product and continuously cover the surface with fresh gas, the etched part will not be covered by the material (for example, the semiconductor materials industry uses chromium as the covering material). Plasma methods can also be used to etch plastic surfaces, and compounds can be ash. As the preparation treatment method of plastic packaging in printing bonding, such as POM, PPS, PTFE, etching method is very necessary, low temperature plasma cleaning machine can significantly increase the wetting area to improve the ability of material surface bonding. 2. Plastic, laminated glass and porcelain surface treatment and cleaning: Plastic, laminated glass and porcelain are commonly used for daily use because of their excellent performance and low price. Fluoroplastics have excellent organic chemical reliability, excellent dielectric properties, extremely low friction resistance and self-lubricating bearing effect, so in some special industries has an important main use. However, during the entire release process of such materials, it is difficult to avoid the problem of weak bonding ability between the same materials or with other materials. Therefore, the reasons for the non-adhesion of the polymer materials and the surface solutions have been discussed. Ion treatment does not damage the sample easily. In addition, it can solve all surface problems very evenly, and it is not easy to cause harmful substances. Hollow products can also be processed, with environmental protection, the indoor space required for work is small, low cost. The practical effect of simple plasma solution can be evaluated according to hydrophilicity, and whether the surface of the specimen after solution is completely wet. 3. Low-temperature plasma coating: The pooling process involves two gases that come into the reaction chamber during the coating and come together in the plasma environment. This use requires more stringent cleaning than plasma surface cleaning. The coating is easy to maintain and is only 1 micron. Common standards include water coatings similar to PTFE material coatings, the purpose of which is to avoid crossing with the hydrophilic coating. 4. Oil removal and purification on the surface of metal materials: Usually, the surface layer of metal material is organic chemical layer and hydroxide layer, such as grease, vegetable grease and so on. In the past, magnetron magnetron sputtering, painting, bonding, arc welding, tin welding and PVD, CVD and other coating, it is necessary to use such ion cleaning machine, in order to get clean and non-reducing surface layer. 5, PTFE etching ash removal: PTFE cannot be packaged, printed or pasted without proper treatment. The use of alkali metals is known to increase suction, but this method is difficult to master and the solution can be harmful. The use of plasma cleaning machine can not only maintain the ecological environment, but also obtain a very good practical effect. PTFE mixtures must be handled with care to prevent excessive filler exposure. Plasma maximizes the benefits of the surface, allowing plastic to be glued together for packaging and printing.

How to complete the display of air pressure alarm of plasma surface treatment machine

How to complete the display of air pressure alarm of plasma surface treatment machine

The reliability and size of the gas pressure in use can be realized by the pressure controller. So plasma surface processor generally how to complete the pressure display and pressure alarm? Today, I'd like to share some knowledge with you. 1. Air pressure visualization: Pressure can be observed in many ways. In general, it is an effective method to install a relief decompression meter in the air passage or part of the air passage. This method is used to display the pressure information of the gas channel on the plasma technology cleaning machine. Generally, the pressure gauge is installed in the embedded hole of the pressure regulating valve. The advantage is that the pressure can be checked immediately when the pressure is adjusted. In addition to the installation of pressure gauges, pressure sensors can also be installed to complete the air pressure display, but the pressure sensor is generally equipped with a display information control module or module. The advantage of this method is that the information can be displayed instantly on the operation panel of the plasma cleaning machine, but it will increase the complexity of programming, and the cost is very high. Therefore, except for special requirements, it is rarely used for plasma cleaning technology. 2. Low pressure gas alarm system: For a plasma surface processor, just looking at the air pressure is not enough. In order to ensure the normal operation of all mechanical equipment, in order to ensure the reliability of the main parameters in the machining process, it is necessary to consider the pneumatic control problem in the design scheme. Because the pressure controller and relief valve are installed on the gas safety channel of the low-temperature plasma cleaner, the larger pressure input to the subsequent gas is limited to a certain range, so the high-pressure monitoring and alarm can be generally ignored, and only the low-pressure alarm maintenance can be carried out. Generally, two methods are used to realize the low pressure alarm of plasma surface processor, namely, the pressure gauge with data signal output and the diaphragm pressure power switch. Pressure gauge used in plasma cleaning machine, its data signal output can be divided into compass type and data display type, in specific applications have been used. The compass manometer has a data signal output and is a mechanical system that is not susceptible to high frequency interference, so it is widely used. When the air pressure is too high in a moment, it will automatically turn off without any alarm signal. When the instantaneous pressure is lower than the alarm display lamp, the display lamp is on, and the internal power supply circuit is converted to complete the alarm output. The data pressure gauge used in the plasma cleaning machine is an electronic digital pressure power switch, which can complete the real-time data display of air pressure and the output of pressure alarm. Both the instantaneous pressure and the set low pressure display information in the form of data, which has strong visual effectiveness and can reasonably prevent misunderstanding. By mounting the bracket, the data pressure gauge can also be more easily installed in the machine equipment server cabinet. Compared with the needle pressure gauge, its application coordination ability is stronger. The disadvantage of this pressure gauge is that if the operation of the plasma cleaning process is improper, the use of sensors and digital integrated circuit to complete the pressure gauge display information, it is easy to cause high frequency signal interference difficulties. Digital pressure gauges using diaphragm pressure power switch is rarely used at present, the key is used in some plasma surface treatment machines. The pulsed decompression power switch is also a pure mechanical system, which is not susceptible to high-frequency interference and can adjust the pressure according to specific needs. When the air pressure reaches a predetermined value, the internal delay relay closes. Delay relays can be used to complete machine and equipment maintenance and output alarm. In practical application, the delay relay is usually connected with the starting power supply of the plasma surface processor to prevent the damage caused by starting the plasma generator when the air pressure and cyclone are insufficient.
