Plasma cleaner, all you want to know is here

In view of the current support and purchase of our chengfeng intelligent plasma cleaning machine customers, in the process of daily use of the problems encountered, CRF Sing Fung Intelligent Manufacturing engineer with text to summarize the following points (for reference only) : Q: What should I do if I find the test effect is not good? A: Please check whether the color of the pump oil is dull and dirty, and replace the pump oil in time. Q: What if the device doesn't glow? A: 1. Rf lamps do not provide RF; 2. There may be air leakage in the sealing. Q: How do I troubleshoot RF lamps? A: Use the standard test lamp tube of the equipment, put it into the main body cavity, turn on the "RF" switch to "Hi", and judge the RF lamp problem by observing the status of the lamp tube (vacuum is not required in this process). Q: How to solve the sealing problem? A: 1. Ensure that the vacuum pump used can achieve or exceed the minimum pumping speed of 1.4 cubic meters per hour and the ultimate negative pressure is not greater than 200mTorr; 2. Then check whether the vacuum hose, all hose clamps and gas inlet pipe connection parts are correct and tighten, whether the plasma cleaning hatch door is closed correctly, and whether the sealing ring of the door is clean and free of defects. Q: Are there any recommended cleaning process parameters? A: The RF power level should be set to medium or high. 600-800 millitotor pressure and 1-3 minute treatment time are the initial values of the better process parameters. The optimum process parameter values will depend on the sample material and the intended application, and some experiments will be required to determine these optimum values. Q: How to measure the vacuum negative pressure? A: You can ask us to buy corresponding measuring equipment, such as vacuum monitoring unit or gas flow mixer. Q: Why does the pump oil return?

Plasma cleaning technology research

Plasma cleaning operation time, optimize organization parameters and adjust the operation mode of transmission organization, thus improving Plasma organization operation efficiency and reducing cleaning cost. During the production of TFT-LCD module, the main purpose of the pressing zone cleaning is to remove the remaining solid particles and organic substances on the surface of the glass substrate. Solid particles can be removed by brush cleaning and dust-free cloth cleaning, but organic materials require Plasma cleaning. Due to the requirements of the front-end process, there are many organic compounds in the production process, the main common liquid crystal in the liquid crystal irrigation process, UV glue, etc. If these organics cannot be effectively removed, there will be pressing foreign matter, IC pressing migration and other adverse phenomena, resulting in line defects and no picture problems. 1. Plasma cleaning principle Plasma, also known as Plasma, is the product of ultraviolet fluorescence. Plasma is the fourth state of matter after solid, liquid and gas. A plasma is a gas of positively and negatively charged particles containing neutral gas atoms, molecules and free radicals. Organics are mainly compounds composed of C and O elements. Plasma USES electrode discharge to clean organics, which is mainly aimed at some inert materials with weak activity. This type of material is not easy to be activated by acid or alkali. For the small impurities remaining after cleaning, the kinetic energy generated by the high-speed impact of medium gas molecules can be used to achieve the purpose of removal. After cleaning, the use of water droplets on the surface infiltration to form a droplet Angle, is a good method to detect the surface activity of materials. The surface of the activated material is mainly for the cleaning of hydrocarbons, so the kind of compounds are oleophilic, so the Angle of the water drop Angle test will be larger (70° ~ 100 °); After plasma treatment, ions or active radicals in the plasma react easily with hydrocarbons to generate volatile hydrocarbon synthesis, such as CO, CO2, CH4, CHxOy, etc., so the Angle of water droplets after plasma will be small (10° ~ 30 °). 2. Study on Plasma cleaning technology In the Plasma cleaning process, as the electrode works under the electric field, the arc root of the electrode front end is consumed seriously. As the cleaning effect directly affects the pressing effect and the electrode cost is high, it is necessary to formulate the electrode replacement cycle. In addition, the Plasma cleaning time is 12.9s, so it is necessary to optimize the running time of the organization and improve production efficiency. 3, conclusion CRF-plasma studies the service life of the electrode, and tests the Plasma cleaning effect by measuring the droplet Angle, and concludes that the service life of the electrode is 1440h. The time in the Plasma cleaning process is optimized to reduce the time of the Plasma cleaning unit from 12.9s to 8.6s by reducing the waiting time and modifying the transmission mode. Through the study of Plasma cleaning process, it provides a method to solve the parameter setting, improves the utilization rate of equipment and saves the operating cost, which has practical reference significance for reducing the cost and improving the efficiency of key equipment in production.

Plasma treatment makes polymers stick more tightly

(a) polytetrafluoroethylene/polydimethylsiloxane /Cu, (b) polytetrafluoroethylene/polydimethylsiloxane /SUS430, (c) polytetrafluoroethylene/polydimethylsiloxane/glass. Polydimethylsiloxane treated with plasma technology can be used as a substitute for strong adhesives to adhere fluoropolymers to other types of materials. Polymer has the characteristics of light weight, high strength and good stability, and has become an essential material in modern life. However, most polymers do not naturally adhere to other materials. Therefore, it needs to be surface treated with adhesive or corrosive chemical treatment. This has caused great trouble in the food and medical fields, where pollution must be strictly controlled. It is urgent to realize clean bonding of industrial polymers. According to Scientific Report, a team of researchers at Osaka University in Japan has found a breakthrough. They developed a plasma treatment that not only made vulcanized rubber and polytetrafluoroethylene (PTFE) adhere to each other, but also to other materials. "PTFE is sprayed by a helium plasma at 200 ° C and sticks to unvulcanized rubber," says Yuji Ohkubo, author of the paper. This problem has been solved in our earlier research. But vulcanized rubber is more challenging. To this end, we have developed a novel plasma treatment for vulcanized silicone rubber that is tightly bound to PTFE. The silicone rubber mentioned by Nkubo Yuji mainly refers to polydimethylsiloxane (PDMS). The key to the adhesion of PTFE is thermo-assisted plasma treatment. For PDMS, the trick is to bombish the surface with a plasma jet, breaking the silicon-carbon bonds on the surface and converting them into silanols. The newly produced silanols are more surface active and can bind to PTFE. Then, under high pressure conditions, silanols form hydrogen bonds with oxygen-containing functional groups in the treated PTFE, thus forming a strong bonding effect. By bonding the two materials together, the new material combines the chemical resistance, scale resistance and slip resistance of PTFE with the elasticity of silicone rubber. PTFE can be replaced with perfluorane, which is more transparent, if the material transparency is required. More significantly, when the back of the PDMS is also treated with plasma technology, it can bond with copper or even glass. Plasma-treated PDMS act like double-sided tape, allowing the polymer to adhere "cleanly" to other material surfaces. Co-author Katsuyoshi Endo explained: "The new adhesion effect could make PTFE and PDMS more versatile in medical and food technologies. We hope that this non-binder bonding technology will broaden the range of polymer applications in high-tech fields."

Plasma technology replaces traditional technology to make shoes more environmentally friendly

Plasma technology has been widely used in chemical industry, material science, environmental protection and other fields. Its technical means is to activate the surface of different materials through plasma to adapt to the technical requirements of the next process, but does not change the surface and properties of the materials. Because it can replace the original pollution, harmful to human health process and operation, to achieve the purpose of eliminating pollution, purify the environment, and protect the health of employees, and is regarded as a technological revolution. Plasma technology replaces treating agent to treat shoe material surface, it has many advantages such as good treatment effect, eliminating pollution, saving electricity and energy, reducing cost, reducing labor, etc. It is a major innovation in shoemaking technology in recent years. One of the key points of sustainable development is to take the green, safe and healthy road of new industrialization. At present, the environmental problems are the organic solvent adhesives and treating agents used in the process. These two dosage forms of materials, because of the benzene, ketone volatile organic solvents, to the human body and the environment is very harmful, has become the target of the industry. At present, organic solvent adhesives are gradually replaced by water-soluble environmental adhesives, which makes the treating agent become the pollution source in the production environment. Therefore, the industry is in urgent need of alternative dosage forms or technologies to change the status quo. The application of plasma to shoe material technology can replace brush treating agent process, and it is superior to the original technology in many technical indexes, which can solve this technical problem well. CRF-plasma Sing Fung Intelligent Manufacturing is a high-tech enterprise specialized in the application of low-temperature Plasma technology. A variety of low temperature plasma surface treatment technologies and equipment suitable for different fields have been developed to realize the application of this technology in the shoe industry. In the process of development, repeated tests have been carried out on a variety of shoe materials. The test results show that the tension value of the shoe materials treated with plasma technology is about 15-20% higher than the standard value, which proves that the technology is feasible and excellent. However, the diversity of shoe materials leads to the application problem of plasma technology, that is, it is impossible to treat different materials with different process parameters in actual production. After the optimization of processing technology and parameters, a breakthrough in technology has been made. A variety of shoe materials can be treated with a single plasma process, and a single plasma process can also be used to replace multiple processes before brushing treating agent, such as washing, sand washing and irradiation in outsole production, etc., thus simplifying the process, saving labor and reducing cost. The most important part of this technology is the transformation of technology into application equipment. Plasma processing technology has made three breakthroughs in the field of shoemaking, including technology, process and equipment, which meet the requirements of shoemaking enterprises on production efficiency, material characteristics and operation mode. In terms of economic benefits, the plasma treatment technology has high efficiency, low operating cost and 30-40% reduction in unit power consumption. 100% cost saving of treating agent is equivalent to no consumption of oil, saving natural resources; In terms of environmental benefits, plasma treatment technology replaces treating agents, eliminates volatile organic matter (VOC) emissions, cleans the production environment, and maximally protects the health of employees. In terms of social benefits, plasma treatment technology can realize green manufacturing, optimize the production environment, reduce the residue of harmful substances in finished shoes, and protect the interests of consumers. Promote the transformation and upgrading of traditional industries to improve the competitiveness of footwear products.

Why is plasma surface treatment developing so fast

With the rapid development of high-tech industry, various processes have higher and higher technical requirements for products. The emergence of plasma surface treatment technology has not only improved product performance and production efficiency, but also achieved safety and environmental protection effect. Plasma surface treatment technology can be applied in the fields of materials science, polymer science, biomedical materials science, microfluidics research, microelectromechanical system research, optics, microscopy and dentistry. It is this extensive application field and huge development space that make the plasma surface treatment technology develop rapidly in foreign developed countries. According to the survey data, the total output value of the plasma surface treatment equipment in the world reached more than 300 billion yuan in 2008. However, we have to wonder why plasma surface treatment technology has developed so rapidly in just 20 years. (1) Principle and application of plasma surface treatment technology: Plasma, or the fourth state of matter, is an ionized gas composed of atoms that have been stripped of some of their electrons and the positive and negative electrons created by ionized atoms. This ionized gas is made up of atoms, molecules, atomic groups, ions, and electrons. Its action on the surface of the object can realize the object super-clean cleaning, object surface activation, etching, finishing and plasma surface coating. According to the difference of particles in the plasma, the specific principle of object processing is different, and the different input gas and control power realize the diversification of object processing. Because the strength of low-temperature plasma on the surface of the object is less than that of high-temperature plasma, it can achieve the protection effect on the surface of the treated object. In applications, we mostly use low-temperature plasma. And different kinds of particles behave differently in the way they treat an object. Radicals. It is mainly to realize the "activation" effect of energy transfer in the process of chemical reaction on the surface of objects. The effect of electrons on the surface of an object mainly includes two aspects: On the one hand is the impact on the surface of the object, on the other hand is caused by a large number of electron impact chemical reaction; The surface of the object is treated by ion sputtering. Ultraviolet light breaks down molecular bonds on the surface of an object and enhances penetration. (2) The advantages of plasma surface treatment technology are dry treatment technology, which has the following advantages instead of traditional wet treatment technology: 1. Environmental protection technology: The plasma action process is a gas-solid coherent reaction, which does not consume water resources and does not need to add chemical agents 2. High efficiency: The whole process can be completed in a relatively short time 3. Low cost: the device is simple, easy to operate and maintain, a small amount of gas instead of expensive cleaning liquid, and there is no waste liquid treatment cost 4. More refined processing: able to penetrate into the interior of fine holes and depressions and complete cleaning tasks 5. Wide applicability: Plasma surface treatment technology is capable of treating most solid substances, so it has a wide range of applications. (3) the prospect of plasma surface treatment technology: With the development of electronic information industry, especially in communications products, computers and parts, semiconductor, LCD and optoelectronic products of ultra-precision industrial cleaning equipment and high value-added equipment requirements gradually increase, the proportion of the plasma surface treatment equipment has become the basis of a lot of electronic information industry. And along with the industry technical requirement unceasing enhancement, the plasma cleaning technology will have the broader development space in the domestic. With the rapid development of the automobile industry, many foreign manufacturers have targeted to the Chinese market, and many spare parts manufacturers have also moved to China, which have put forward new technical requirements for cleaning. It can be said that plasma cleaning technology is more suitable for the development of the automobile industry. The treatment process before the use of medical devices is very fine, cleaning with freon is not only a waste of resources but also very expensive. The use of plasma surface treatment technology avoids the disadvantages of using chemical substances, and it is more suitable for the technical requirements of modern medical technology. The cleaning technology of optical devices and some optical products is very high, and the plasma surface treatment technology can be more widely used in this field. Plasma surface treatment technology can be use
