Working principle of plasma spray gun plasma spray gun spraying range decryption

Working principle of plasma spray gun plasma spray gun spraying range decryption

Working principle of plasma spray gun plasma spray gun spraying range decryption Working principle of plasma spray gun: plasma spray gun is an important part of atmospheric plasma jet. Jetting range The surface of the material to be treated is generally within a plasma spray range of 5 to 30 mm through the area with the plasma nozzle. Working principle of plasma spray gun Plasma spray gun is an important part of the formation of plasma jet. The plasma spray gun will produce a certain temperature when working. When installing the plasma spray gun, it can be combined with the metal bracket as far as possible to facilitate heat dissipation. The material generally moves in a pipelined fashion through the opening of the plasma gun. Note: during the work, the material to be processed must not be left standing in the plasma spray area for a long time, so as not to be damaged by high temperature or have the risk of burning! In the process of use to prevent hand contact and scald! The voltage of plasma spray gun and its contained cable is too high, pay attention to prevent accidental damage resulting in electric shock danger! Power must be cut off before opening the case for cleaning. When there are ceramic materials in the plasma spray gun, it can be avoided to be damaged by impact when moving, installing and using. After a long time of use, the plasma gun will produce a certain amount of pollution in the body, which requires regular maintenance, cleaning and timely replacement of the wear and tear parts. Plasma cleaning machine equipment installation and maintenance. 1, spray gun installation: Install the plasma spray gun on the appropriate fixing bracket or mechanical hand, and take appropriate fixing measures to prevent the strong pull, friction and piercing of the high voltage cable, ground wire and air pipe on the spray head. Adjust the distance between the nozzle and the workpiece to be processed so that it is between 8 and 12 mm. (The treatment distance should be adjusted according to the material test, the speed and the subsequent process. The closer the relative distance is, the greater the treatment intensity will be, but too close will burn the material.) 2. Host installation: When the equipment is working, the fan and ventilation window of the main engine should not be blocked by objects. The host can not be placed close to the large area of iron surface, the distance between the equipment and such materials should be more than 10cm. In addition, eddy current losses can increase power consumption and increase equipment temperature rise.

Application of low temperature plasma surface modification machine technology and equipment on materials

Application of low temperature plasma surface modification machine technology and equipment on materials

Application of low temperature plasma surface modification machine technology and equipment on materials Low-temperature plasma surface modification machine technology equipment can be used to prepare hydrophilic substances, change the product surface value for printing use, after treatment and then use adhesives or ink can be very good to achieve the bonding effect, usually called plasma surface modification, this method is used to make the object become hydrophilic (wettability). A hydrophobic surface repels water and is considered non-wettable. Duck feathers, for example, are hydrophobic, and water flows over the surface rather than over the feathers. Low-temperature plasma surface modification machine technology equipment PTFE or plastic is often treated with low-temperature plasma surface modification machine technology equipment, so that the surface is more "wet-able", thus improving the adhesion and printing performance. This is a common purpose when we perform plasma cleaning. The low-temperature plasma surface modifier technology device actually changes the surface of the material by several layers of monolayer film, leaving free radicals on the surface and binding with glue or ink. This is especially useful when bonding different surfaces, such as plastic or metal. The surface is different, the binder is different; This makes it difficult to find a suitable adhesive. Look for connections that use plasma to change the surface, leaving extra electrons on the plastic or rubber surface. This can make the surface adhesion, strength greatly improved. Plastic surface is smooth, usually printed or adhered to other materials, such as plastic or metal bonding treatment is not strong. When these smooth surfaces are treated with plasma, the added surface allows for direct printing without coating. This effect is quite brief, ranging from a few hours to a few days, and there is enough time to complete the process of processing the material. Low-temperature plasma surface modification machine technology, such as vacuum plasma treatment, has more advantages than pneumatic plasma technology. Negative pressure plasma system makes the action of plasma longer and provides excellent surface improvement treatment. Atmospheric plasma systems are usually easier to install on assembly lines, or to handle large products in small areas.

Plasma Cleaning Process Application of Plasma Cleaning to Bonding Line

Plasma Cleaning Process Application of Plasma Cleaning to Bonding Line

Plasma Cleaning Process Application of Plasma Cleaning to Bonding Line At present, the development trend of integrated circuit is miniaturization, high power and multi-function, and the users' requirements for the reliability of products are becoming higher and higher, which puts forward many new problems for the microelectronics manufacturing technology and process. The failure of the bonding line is one of the main reasons for the circuit failure in the manufacturing process of Thick and Thin Film Hybrid IC. According to statistics, more than 70% of the product failures of hybrid integrated circuits are caused by the failure of bond lines. The reason is that the bonding zone will inevitably be polluted in the production process. If the bonding zone is directly bonded without treatment, it will cause defects such as false welding, unwelding, low bonding strength and so on, so that the long-term reliability of the product is not guaranteed. Plasma cleaning process can effectively remove photoresist, solvent residue, epoxy spillage and other organic pollutants in the bonding zone. Therefore, plasma cleaning treatment before bonding can greatly reduce the failure rate of bonding and improve the reliability of products. Plasma cleaning has the characteristics of cleaning clean, not damaging the chip, not reducing the adhesion of the film layer, and it has incomparable advantages over conventional liquid phase cleaning: From the working principle, it uses electric energy to produce a low-temperature working environment, without affecting the bonding (welding) of the components and the performance of the components themselves. At the same time, the plasma cleaning also eliminates the danger and trouble caused by chemical reaction. Isogenous cleaning produces gaseous material, rather than liquid waste, which can be discharged directly into the air. This eliminates the need for expensive waste disposal systems. Plasma cleaning is through the selection and adjustment of process parameters such as power, pressure, time, gas type and other process control, easy to operate, simple. In the plasma cleaning process, high-energy electrons collide with gas molecules to dissociate or ionize them. A variety of particles generated can be used to bombardment the surface to be cleaned or react with the surface to be cleaned, so as to effectively remove organic pollutants on the surface to be cleaned or improve the surface state. In the process of plasma cleaning with Ar gas, the huge energy generated by the impact of Ar ions on the surface can remove organic pollutants, and the mechanical energy generated by the bombardment can separate the chemical bonds of large molecules in the polymer into small molecules and vaporize them. In the process of plasma cleaning with O2, oxygen ions react with organic molecules to form H2O or CO2 gasification. When cleaning with a mixture of Ar and O2, the reaction rate is much faster than using any single gas. The argon ion is accelerated by negative bias pressure, and the kinetic energy formed can improve the reaction ability of oxygen. In this way, the surface of the device which is seriously polluted can be cleaned. Plasma cleaning process before bonding Plasma cleaning function: (1) The bonding strength generally increases after cleaning; (2) The range decreases after cleaning; (3) The discreteness of bonding strength decreases after cleaning; (4) Cleaning improves the failure mode. Plasma cleaning process before the bonding line can effectively remove the organic pollutants brought by various processes in the film bonding zone. So as to achieve the purpose of improving the bonding strength and reducing the desoldering. Plasma cleaning can reduce the product failure caused by bonding failure, and provide a powerful process guarantee to increase the long-term reliability of bonding and improve the quality of products.

Plasma treatment equipment in medical antibacterial and furniture bonding treatment

Plasma treatment equipment in medical antibacterial and furniture bonding treatment:        With the improvement of social hygiene standards, the role of antibacterial surfaces is becoming more and more important. Especially life science and medical technology have higher requirements for health. Therefore, the application of the antibacterial surface is uniform, gentle and sustainable. With the help of plasma treatment equipment plasma surface activation technology, we can now deposit fine particles on the surface of the silver base. The experimental results show that the plating layer is uniform, the silver layer has good antibacterial properties, and the permeability changes in a short period of time. Plasma processing equipment        The seamless connection between the board and the edge (zero bonding line) is one of the important features of modern furniture. Therefore, it is very important to open the invisible boundary. The usual method is to glue the edge of the furniture to the veneer with an adhesive. However, this method will significantly darken the bonding line. The plasma treatment equipment can easily improve the adhesion to prevent the glue from flowing out.        The application of adhesives is replaced by functional layers of polymers. Some manufacturers provide plasma treatment for plasma treatment equipment, using plasma to activate the functional layer, so that the edge banding machine can directly bond the slats to the furniture board, so that the slats can achieve a good sealing effect, and the quality standards are continuously improved. And to meet the requirements for service life and durability.

Application of power battery plasma cleaning machine technology in electronic printing and other industries

Application of power battery plasma cleaning machine technology in electronic printing and other industries

Application of power battery plasma cleaning machine technology in electronic printing and other industries:         Plasma cleaning machine technology in the power battery pretreatment process enables the material to produce good adhesion in the subsequent bonding process, while ensuring clear and effective quality assurance. The surface of the electronic product after plasma treatment is improved The adhesion effect has become very important and necessary. Power battery plasma cleaning machine         In recent years, the pretreatment technology of plasma cleaners can greatly improve the adhesion of various materials while ensuring the quality of the cleaning agent. At present, for various electronic applications, such as PCB boards, FPC flexible circuit boards, LED packaging and other electronic industries, customer expectations are optimistic. Since electronic products do not have high adhesion, it is very important and necessary to improve the surface adhesion effect of products through plasma treatment.         Electric vehicles, networking and autonomous driving are the driving forces of innovation in the automotive industry, and power batteries are now vigorously promoted. Due to climate change, the declining fossil fuels, and the increasing demand for action due to population growth, new solutions and alternative drive systems are required. The global automotive industry is vigorously promoting the development of electric vehicles. Electric vehicles can make a major contribution to environmental protection and emission reduction. Contribution, and the treatment of the plasma cleaner on its parts has become inseparable.         The electrification of automobiles has become more and more important and supports the development of the entire electric vehicle system. Use plug-in hybrid vehicles, range extender vehicles, fuel cell vehicles, battery vehicles and other electric vehicles connected to energy systems and transportation systems. The impact of the quality and quantity of the new components on the results is unpredictable. In fact, such products must be reasonable in terms of price and technology, and the application of power battery plasma cleaning machine technology is indispensable. Aluminum, plastics, especially bioplastics will be the future development direction. To handle materials, a good bonding process must be ensured. Adhesives and sealants require clean and active surfaces.         Other components also need functional layers: the plasma cleaner coating technology has anti-corrosion layers on different metals to prevent corrosion, and then combined with subsequent processes. Due to the emergence of new technologies and new materials, Hyundai Packaging has assumed new responsibilities. For example, there is a need to prevent product piracy or prevent improper use. Self-adhesive label technology is increasingly becoming an effective protection technology. The goal of the pharmaceutical industry is to make the safe production of carton chemicals even higher. After plasma pretreatment, the label is affixed to a small diameter and a compact radius, and even the beginning and end labels of the key areas can be kept in good condition. This label is completely tamper-proof.         The mechatronics design of the plasma cleaner is very simple: the closed pre-treatment is carried out directly or indirectly as part of the label. Therefore, surface pretreatment is part of the process to provide safety guarantees for products and customers. Through long-term research and development, it is now possible to improve the adhesion of digital printing inks during UV curing of glass. In order to achieve this goal, plasma cleaning must be used first for subsequent surface treatment of the coating. Because the paint is transparent, it will not affect the transparency of the glass. Now the glass can be printed as usual. Multiple studies have evaluated the consistency and quality of ink adhesion, proving the success of the recording. The cleaning effect of plasma cleaning machine is efficient, uniform and stable.
