Plasma treatment can significantly improve the coating of polymer ceramic materials, metallic glasses or diamond-like material

Plasma treatment can significantly improve the coating of polymer ceramic materials, metallic glasses or diamond-like material

Plasma treatment can significantly improve the coating of polymer ceramic materials, metallic glasses or diamond-like materials: Plasma processing offers the possibility to obtain innovative finishing functions on one or both sides of fabrics. A suitable plasma device configuration can be used to treat a single piece of clothing or shoe, creating a huge opportunity for branding and marketing. The big advantage of plasma treatment is that it provides an option for dry processing of textile materials. Solvent-based processing equipment uses organic solvents. The cost is much higher than water, and the equipment must be equipped with an efficient solvent recovery system to meet the necessary economic and environmental demands of the process. The processing technology using water as the medium will generate a large burden of wastewater pollution, resulting in an increase in the cost of wastewater treatment and disposal. Furthermore, removing moisture from textile materials is an energy-intensive process. Usually, the moisture in textile materials is removed as much as possible by mechanical dehydration, such as centrifugal dehydration, open-width calendering, and vacuum suction. The larger the capillary area in the textile structure and the heavier the grammage of the textile, the more difficult it is to mechanically remove moisture. The higher the proportion of hydrophilic fibers in the textile, the greater the residual moisture after dehydration, because such fibers have a higher fiber-saturation value. Plasma treatment is an air-dried textile material, which is an energy-efficient and economical choice compared to traditional water-based processing. At present, the main processing technology of textiles usually refers to wet processing technology. During the plasma treatment, the textiles are kept dry, and the costly heating and drying process can be omitted. In addition, no water is needed in the plasma treatment process, so there is no need to soften the water, and no waste water is generated. Plasma treatment therefore offers both economical and ecological advantages and offers dyeing, printing and finishing workers the opportunity to develop innovative processes to achieve novel finishing effects. The plasma process is considered to be a more environmentally friendly processing method than traditional wet processing of textiles. Plasma treatment is only carried out on the surface of the substrate, so physical or chemical modification is limited to the outermost layer of the fabric. Under normal processing conditions, most of the properties of the fabric were not affected. After the fiber surface is treated with plasma, the dirt on the fiber surface, such as natural impurities (wax), or added impurities (slurry) can be removed. The ablation/cleaning process can also modify the physical structure of the fiber surface through the erosion of the polymer material. In addition, the functionalization of the fiber surface layer with chemical groups also helps to improve the adhesion during coating/lamination treatment. The chemical groups on the fiber surface can act as reaction points for subsequent dyeing, printing or finishing. Plasma treatment can significantly improve the wear resistance of polymer, ceramic, metal, glass or diamond-like coatings in end-use applications. Plasma treatment can be used to achieve functional polymer coating on fibers, and the interior of the coating has a gradient along the thickness of the coating, so that different properties can be obtained. In composite materials, the interface of the matrix material is the key to determine the mechanical/chemical properties of the material. Plasma treatment improves composite properties such as interlaminar shear strength, fatigue resistance, delamination, and corrosion. Improvements in the interfacial reactivity of composites, including plasma-induced enhancement of surface adhesion, are achieved through microetching and mechanical interlocking, as well as changing surface chemistry. This performance enhancement is important for textile coating and lamination processing, as the adhesion of coating and laminating films to fabrics is critical for the product to achieve the highest end-use properties.

Plasma surface treatment equipment treatment technology solves the difficulty of bonding and stripping in the automotive mobile phone industry

Plasma surface treatment equipment treatment technology solves the difficulty of bonding and stripping in the automotive mobile phone industry

Plasma surface treatment equipment treatment technology solves the difficulty of bonding and stripping in the automotive mobile phone industry: Due to the low surface tension of most plastics, many designs in the past used alternative materials. As long as the surface can meet the process requirements of spraying or bonding after being treated by plasma surface treatment equipment, this material is preferred. In recent years, cost and material performance have increasingly become dominant factors in product design, prompting automakers to focus on more plastic varieties. At present, PP, PC, ABS, SMC, various elastomers and various composite materials are widely used in automobile manufacturing. This not only solves the problem of bonding between parts of the same material, but also solves the problem of bonding between parts of different materials, making it difficult for the previous traditional processing methods to meet the requirements of this processing technology. Mobile phones are also one of the indispensable tools in modern life. However, the troublesome thing is that after using the mobile phone for a period of time, it is found that the casing will peel off, wear, or the logo will become more and more clear, which seriously affects the appearance of the mobile phone. The use of plasma surface treatment machine technology has helped mobile phone manufacturers completely solve the above problems. It can be said that plasma surface treatment equipment is a new environmental protection technology on the market, which completely replaces the traditional method of relying on chemicals to surface treatment mobile phone casings. As far as the surface treatment effect is concerned, among the various surface treatment methods at present, the fluorination treatment effect is good, and the bonding ability of the material can be obtained. But this method produces a lot of harmful gases, and the emissions bill is out of reach for most automakers. It is gratifying that the emergence of plasma surface treatment technology has brought new changes to the plastics industry. The whole process can be completed in a short time. The equipment is simple, the operation and maintenance are convenient, only a small amount of gas can replace the expensive detergent, and there is no need to deal with the waste liquid. It can penetrate deep into pores and depressions to complete cleaning tasks. Plasma surface treatment technology can realize the treatment of most solid substances, so its application range is very wide. The mobile phone car shell made by the surface treatment technology of the plasma surface treatment equipment has better wear resistance after being treated by the equipment, which can ensure that the paint will not peel off or grind the paint after long-term use. The use of plasma surface treatment machine technology can clean the residual dust, impurities and oil in the production process. Larger process scale can improve the surface activity of plastics, make the coating film effect very uniform, and the coating film bonding effect is better. Layer connections are stronger.

The application of six types of surface treatment plasma cleaners removes residues on the surface of products

The application of six types of surface treatment plasma cleaners removes residues on the surface of products

The application of six types of surface treatment plasma cleaners removes residues on the surface of products: In view of the wide application of plasma cleaners in all walks of life, CRF Chengfeng Zhizao Xiaobian summarized 6 solutions for the application of plasma cleaners. The solution to surface activation, after treatment with plasma surface treatment machine, can improve surface energy, hydrophilicity, increase adhesion, adhesion strength, etc. In the cleaning process, the plasma surface treatment machine is used in conjunction with different gases, and the dirt effect of the cleaning residues is also very different. Among these gases, the inert gas argon (Ar) is commonly used, which is often used in conjunction with argon in the cleaning process of vacuum equipment, which can effectively remove nano-scale pollutants on the surface. The solution to the etching of the material surface is to selectively use the reactive gas plasma to corrode the material surface, so that the impurities on the corroded material are converted into gas, and then discharged through a vacuum pump. Hydrophilic. In order to enhance the etching effect, oxygen (O2) can be introduced, which can effectively remove organic pollutants such as photoresist. Nano coating solution, through the treatment of plasma cleaning machine, plasma guide polymerization to form nano coating. Various materials can obtain hydrophobicity (hydrophobicity), hydrophilicity (hydrophilic), lipophobicity (anti-fat), and oleophobicity (anti-oil) through surface coating. There is also some hydrogen (H2) that can be used in combination with other oxides that are difficult to remove, usually using a hydrogen-nitrogen gas mixture (95% nitrogen mixed with 5% hydrogen). TSP/OLED product solutions, in terms of TSP: cleaning the main process of the touch screen, improving the adhesion/coating force on OCA/OCR, lamination, ACF, AR/AF and other processes, through various atmospheric pressure plasma It can eliminate air bubbles/foreign objects, and evenly discharge various glasses and films, so that the surface is not damaged. Nitrogen (N2) is a widely used gas and its production cost is low. The gas of the present invention is mainly combined with the online plasma cleaning machine technology to perform surface activation modification on the material. Can also be used in vacuum environments. Nitrogen (N2) is a gas that improves the wettability of material surfaces. The solution for vacuum plasma cleaning machine equipment, due to the high energy density in the vacuum plasma, virtually all powders with a stable molten phase can be transformed into dense, firmly attached spray coatings, and the quality of the coating depends on The instantaneous melting degree when the sprayed powder particles hit the surface of the workpiece. Vacuum plasma spray technology provides a new way for the production of modern coating machines. The surface cleaning solution uses radio frequency power to generate high-energy, disordered plasma in the vacuum plasma cavity, and the surface of the cleaned product is bombarded by the plasma, so that the surface contaminants are detached from the product, so as to achieve the purpose of cleaning. In addition, there are some special gases, such as carbon tetrafluoride (CF4), sulfur hexafluoride (SF6), etc., the use of these gases in the plasma cleaner is more important for the etching and removal of organic substances.

Comprehensive analysis of vacuum low temperature plasma cleaning equipment to improve the treatment effect

Comprehensive analysis of vacuum low temperature plasma cleaning equipment to improve the treatment effect

Comprehensive analysis of vacuum low temperature plasma cleaning equipment to improve the treatment effect: In recent years, with the continuous development of science and technology, the application of plasma surface treatment machine cleaning equipment has become more and more extensive. It can be used for surface activation and modification of materials, improving adhesion and adhesion, etc. , optics, electronics, medicine, environmental protection, biology and other fields, the emergence of vacuum low-temperature plasma cleaning equipment has enabled people to have a better understanding of the cleaning of their products in a vacuum environment. Some people may ask: "Why vacuum cleaning?" Because cleaning in a vacuum environment can achieve stronger processing results. The product is placed in a sealed cavity and continuously pumped. Assuming that there are small particles on the surface of the product, such as dust, they can be removed according to the continuous pumping time. The continuous pumping time means that the vacuum state must be maintained at a relatively stable vacuum state. In addition, the charging and discharging of low temperature plasma cleaning equipment must be in a stable vacuum environment. The plasma surface treatment machine has low cost, simple and flexible operation, and can easily change the type of treatment gas and treatment process parameters; it will not cause any harm to the operator's body during use; for the treatment method of the plasma surface treatment machine, the cost is low , and has objective cost performance and advantages; from the perspective of environmental protection, the entire process of plasma surface treatment machine cleaning equipment is pollution-free, pollution-free, and green. Most of the vacuum low temperature plasma cleaning machine equipment adopts vacuum drying to pump the oil pump cavity. Some applications are stand-alone, others are combined. Low temperature plasma cleaning machine, small and medium vacuum pump. The actual operation control panel is mainly composed of buttons, status indicators, passive buzzers and display lights, output power controllers, data display vacuum gauges, timers, knob switches and total float flow. It consists of the dashboard and other components. The start and stop control of the vacuum pump is an instant control of the DC contactor through a lockable on-off light-emitting key. The contact point of the DC type contactor is connected, and the three-phase power supply of the control vacuum pump is connected and disconnected. This control method can fully take into account the control requirements of small and medium-sized plasma cleaners. If this method is used to achieve fully automatic control, it is not only difficult, but also the accuracy requirements and control safety factors are difficult to specify. The use of plasma surface treatment machine can keep operators away from the harm of harmful solvents to the human body, and also avoid the problem of easy damage to objects during wet cleaning; avoid the use of ODS harmful solvents, so that no harmful pollutants will be generated after washing, so it belongs to Environmentally friendly green cleaning methods have become increasingly important under the high attention of global environmental protection. After the equipment is cleaned by the plasma surface treatment machine, the cleaning object is dry, and it can be sent to the next process without air-drying or drying treatment, which can improve the processing efficiency of the entire process pipeline. Plasma generated by high frequency is different from direct light such as laser. The direction of movement of the plasma is scattered, which allows it to penetrate into the small holes and depressions inside the object to complete 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, the cleaning effect is similar or better than that of Freon. Therefore, vacuum low-temperature plasma cleaning equipment is widely used in high-tech industries, especially in automobiles, semiconductors, microelectronics, integrated circuits, vacuum electronics and other industries. An indispensable link is the key to improving product quality. The basic principle of most of the manual control is similar to the experimental vacuum low temperature plasma cleaner. Press the relative key to turn on the vacuum pump. The difference is that one key controls the hardware configuration and the other is controlled via virtual keys on the touch screen. The hardware configuration of the keyboard driver is the electromagnetic coil of the automobile relay and the soft element of the touch screen keyboard driver controller. On the basis of the logic measurement, the controller outputs the measurement results to the output terminal of the controller, the position of the small relay of the driver, the contact point of the driver, and the contact p

The plasma surface treatment device improves the specific properties of the surface of the PTFE material for lithium batteries

The plasma surface treatment device improves the specific properties of the surface of the PTFE material for lithium batteries

The plasma surface treatment device improves the specific properties of the surface of the PTFE material for lithium batteries: The electric lithium battery is a commonly used lithium battery, which is driven by the display of the pneumatic tool. It is a clean and environmentally friendly power supply. At present, it has been widely used in pure electric vehicles, electric trains, electric vehicles and other fields. In recent years, with the rise of the new energy vehicle sales market, the safety and reliability of power lithium batteries has become a focus of attention and discussion. This is not only because the power lithium battery is a key component in the power drive system software, but also because the power lithium battery production process itself has high reliability and reliability requirements. For example, for lithium batteries for automobiles, what role can the plasma surface treatment device play in the production and manufacture of power lithium batteries? How can I help? When the plasma etching temperature is low, the etched object is transformed into the gas phase. A mechanical pump is used to discharge the excess product, and the surface is continuously covered with fresh gas, so that the corroded part is not covered by the material (for example, chromium is used as a covering material in the industrial production of semiconductor materials). Plasma methods can also be used to corrode plastic surfaces, ashing these compounds. It is very necessary to use advanced technologies such as POM, PPS and PTFE to corrode printed adhesive packaging. The low temperature plasma surface treatment machine device can greatly increase the wet area and improve the bonding ability of the material surface. In the production process of automotive power lithium batteries, the surface treatment of plasma surface treatment equipment is usually carried out from three aspects, namely, improving the lubricating properties of the ceramic film before coating the positive and negative plates; cleaning the connecting piece before lithium welding; Improve the surface adhesion of insulating plates, end plates, PET plastic films and other metal composite materials and their insulating materials before gluing them and their lithium battery components. Next, I'll give a brief summary of this and go into detail one by one. Based on the positive and battery cathode materials of the ceramic film, the positive and negative stages of the automotive power lithium battery were prepared. Compared with cleaning with aqueous solutions such as ethanol, the plasma surface treatment device not only does not destroy the raw materials, but also can remove organic substances on the surface of the raw materials, improve the lubricity of the film surface, improve the uniformity of the coating, and improve the heat resistance and safety of the coating. coefficient. Plastics, laminated glass and ceramics are often used in daily necessities due to their excellent properties and low prices. Fluoroplastic materials have important application prospects in some special industries due to their excellent organic chemical properties, excellent dielectric properties, extremely low frictional resistance and bearing self-lubrication. However, during the entire release process of this material, it is difficult to avoid the problem of weak adhesion between the same material or between the same material. To this end, we discuss the reasons for the non-bonding of such non-bonding polymers and the surface solutions. Plasma surface conditioner units are not prone to damage to samples. In addition, all surface problems can be solved very uniformly, and harmful substances are not easily generated. Hollow products can also be processed, which is environmentally friendly, requires less indoor space during work, and has low cost. The actual effect can be solved by simple plasma identification according to the hydrophilicity, and the problem of whether the surface of the sample is completely soaked can be solved. The lithium tab actually refers to the correct guide of the metal material strip between the positive and negative electrodes of the rechargeable battery. It is a point-contact type when charging and discharging. Whether the surface of the bonding plate is clean or not directly affects the reliability and performance of electrical bonding. Using a plasma surface treatment device before electric welding can remove the residual organic matter and particles on the surface of the welding seam, making the surface of the welding seam uneven, thereby improving the welding quality. The two gases are brought together so that they enter the reaction chamber during the smearing process, where they polymerize in a plasma environment. The cleaning method used is more stringent than plasma surface cleaning. The coating is easy to maintain and only 1 micron. General criteria include waterborne coatings similar to PTFE material coatings designed to avoid crossover with th
