The effect of low-temperature plasma surface treatment on the inter-turn insulation performance of variable frequency traction motors

The effect of low-temperature plasma surface treatment on the inter-turn insulation performance of variable frequency traction motors

The effect of low-temperature plasma surface treatment on the inter-turn insulation performance of variable frequency traction motors: Polyimide (PI) is used in the turn-to-turn insulation of traction motors of high-speed EMUs due to its excellent dielectric properties. China's high-speed railways have achieved world-renowned achievements through the introduction, digestion, absorption and re-innovation. The frequency conversion traction motor is one of the core equipment of high-speed EMUs. Its speed adjustment is carried out through pulse width modulation (PWM) technology. Due to the short rise time and high frequency of the pulse, the cable and motor terminal Impedance detuning will generate overvoltage, which will impact the inter-turn insulation of the motor, causing its insulation failure and threatening driving safety. Polyimide (PI) is used as the inter-turn insulation material of the variable frequency motor, which uses a 2/3 stacking method to wind the magnet wire, that is, there are three layers of PI film on the magnet wire as the inter-turn insulation of the motor winding. In the process of material preparation, magnet wire winding, etc., defects such as air gaps and wrinkles will inevitably occur between the inter-turn insulating materials of the frequency conversion motor. Studies have shown that the partial discharge in the insulation between the turns of the variable frequency motor is the root cause of the insulation failure of the motor. Therefore, the low-temperature plasma surface treatment can improve the partial discharge resistance of the inter-turn insulation of the inverter motor, which can significantly increase the insulation life of the motor and ensure the safe operation of electric locomotives. In recent years, low-temperature plasma surface treatment technology has been widely used in surface modification of polymer materials. Because of its simple structure and the ability to generate large-scale low-temperature plasma in atmospheric air, it is widely used in industrial production. Low-temperature plasma treatment can cause etching, cross-linking, and group introduction on the surface of the material, thereby significantly changing the surface characteristics of the material, such as hydrophilicity, hydrophobicity, flashover voltage along the surface, surface charge dissipation, space charge accumulation characteristics, etc. . The partial discharge between the insulation of the inverter motor is also a kind of gas discharge that occurs on the surface of the material in the air gap, and its working voltage is a square wave pulse voltage. Increase the intensity of the discharge in the air gap. Therefore, low-temperature plasma surface treatment can be used to only change the surface of the material without affecting the superior characteristics of its internal matrix structure. Plasma surface modification of the polyimide film can be used to improve its insulation performance. The contact angle is a key parameter reflecting the surface energy of the film, which is determined by the surface characteristics of the film. The smaller the contact angle, the stronger the hydrophilicity of the film surface and the greater the surface energy. The modification of materials by plasma is actually a process of interaction between the plasma and the surface of the material. In this process, the etching of the surface of the material, the cross-linking of molecular chains, and the introduction of polar functional groups mainly occur. The highly active plasma ionizes or excites many molecules in the air (such as H2O, 02, N2, etc.) and forms particle products (N2, O2, O, H, ultraviolet light, etc.), which are processed in the plasma During the process, it will bring higher energy and hit the PI film. On the one hand, the PI film will be cross-linked or etched, so that the inert substances in the amorphous area on the surface are eliminated and the active groups are exposed. On the other hand, the active particles will also cause the PI molecular chain to undergo a ring-opening reaction, and introduce -NH2, -COOH, -OH and other polar hydrophilic groups at the end of the molecular chain, thereby improving the hydrophilicity of the surface of the material and the surface can. In addition, the increase of polar groups and the exposure of active materials will also increase the number of carriers on the surface of the material, thereby increasing the surface conductivity of the material. The double-layer film without low-temperature plasma surface treatment is only a simple physical stacking, and it is difficult to form cross-links or cross-connections between the PI molecules between the layers, and thus cannot form a charge transfer channel, which makes Schottky emission or field emission injection into the film The internal electrons are easy to accumulate inside a layer of the film, and it is difficult to reach the second layer. In addition, the low conductivity of the interface between the l

application areas of plasma plasma flame treatment machine

application areas of plasma plasma flame treatment machine: The plasma plasma flame treatment machine is mainly suitable for surface modification treatment of various materials: surface cleaning, surface activation, surface etching, surface grafting, surface deposition, surface polymerization and plasma-assisted chemical vapor deposition. Surface modification: paper bonding, plastic bonding, metal soldering, surface treatment before electroplating; Surface activation: surface modification of biological materials, surface treatment before printing, coating or bonding, such as surface treatment of textiles; Surface etching: micro-processing of silicon, surface etching treatment in solar energy fields such as glass, and surface etching treatment of medical utensils; Surface grafting: the generation of specific groups on the surface of the material and the fixation of surface activation; Surface deposition: plasma polymerization deposition of hydrophobic or hydrophilic layer; Plasma plasma flame treatment machine is widely used in metal, microelectronics, polymers, biological functional materials, low temperature sterilization and pollution control and other fields. It is the ideal equipment for plasma surface treatment of enterprises and research institutes. 1. Application of plasma plasma flame processor in microelectronic packaging In the production process of microelectronic packaging, various surface contaminations, including organic matter, epoxy resin, photoresist and solder, metal salt, etc., will be formed due to various fingerprints, fluxes, cross-contamination, natural oxidation, devices and materials. These stains will have a significant impact on the packaging production process and quality. The use of plasma cleaning machine can easily remove the contamination formed in the molecular-level production process to ensure that atoms and atoms are in close contact with the surface of the workpiece, thereby effectively improving the bonding strength, improving the quality of wafer bonding, and reducing the leakage rate , Improve packaging performance, output and component reliability. The choice of the cleaning process of plasma plasma flame treatment machine for electronic packaging depends on the requirements of subsequent processes on the surface of the material, the original characteristic chemical composition and the nature of the contaminants on the surface of the material. Commonly used in plasma cleaning gas argon, oxygen, hydrogen, carbon tetrafluoride and their mixed gases. Table, choice of plasma cleaning technology application. Small silver glue village bottom: Pollutants will cause the colloidal silver to be spherical, which is not conducive to chip sticking, and it is easy to stab the chip manual. The use of radio frequency plasma cleaning can greatly improve the surface roughness and hydrophilicity, which is beneficial to the silver colloid and Tiles are pasted with chips, and the amount of use at the same time can save silver glue and reduce costs. Wire bonding: Before the chip is bonded to the substrate and after high temperature curing, the existing contaminants may contain microparticles and oxides. The physical and chemical reactions of these contaminants lead and the soldering between the chip and the substrate is incomplete, and the bonding strength is poor. , Adhesion is not enough. Before wire bonding, plasma cleaning by plasma plasma flame treatment machine can significantly improve the surface activity and increase the bonding strength and tensile strength of the bonding wire. The pressure on the welding head can be low (when there are contaminants, the welding head penetrates the contaminants, more pressure is required), and in some cases, the bonding temperature can also be lowered, thereby increasing production and reducing costs. Sealing glue: In the epoxy resin process, pollutants will cause high foaming rate, resulting in low product quality and service life, so in order to avoid the formation of sealing foam, we also pay attention to it. After the radio frequency plasma cleaning, the chip and the substrate will be more closely combined with the colloid, the foam formed will be greatly reduced, and the heat dissipation rate and light emissivity will be significantly improved. ⒉The mechanism of plasma plasma flame treatment machine in rubber and plastic industry products I have found in industrial applications that some rubber and plastic parts have difficulty in bonding when they are connected to the surface. This is because polypropylene, PTFE and other rubber and plastic materials have no polarity. These materials have not undergone surface treatment. The effect of printing, bonding, coating, etc. in the state of being very poor, or even impossible. Some processes use some chemicals to treat these stolen plastic surfaces, which can change the bonding effect of the material, but this method is not easy to master. The chemicals themselves are toxic, the operation is very

Chengfeng Zhizhi plasma equipment manufacturer will introduce you the influencing factors of PEF plasma treatment

Chengfeng Zhizhi plasma equipment manufacturer will introduce you the influencing factors of PEF plasma treatment: In previous articles, the basic principles and typical models of PEF plasma treatment have been introduced, and the following content mainly introduces the related content of the factors that affect PEF plasma treatment. In fact, the main parameters that affect the effect of PEF plasma treatment can be divided into three categories: material characteristic parameters, processed medium characteristic parameters and processing process parameters. The plasma equipment manufacturer of Chengfeng Zhizhi will introduce you the detailed information below. Plasma equipment PEF plasma treatment influencing factors The cell characteristic parameters of the material: The cells treated by the plasma method are mainly manifested in the type of microorganisms, the area, shape and growth cycle of the cells. Characteristic parameters of the treated medium that affect the PEF plasma treatment of the plasma equipment: The characteristic parameters of the processing medium, or the characteristic parameters of the food in the food field, mainly include the electrical conductivity, acidity and alkalinity, water quality of the food, and the composition of the processing medium. pH is an important external parameter in the process of cell growth, and the activity of water affects the osmotic pressure inside and outside the microbial cell membrane. Treatment process parameters of the influencing factors of PEF plasma treatment of plasma equipment: The process parameters during processing mainly include: electric field strength, pulse waveform, pulse width, processing time, frequency, energy, processing temperature, etc. The intensity of the pulse field and the processing time are important factors that affect the effect of PEF processing. Compared with the exponential wave, the square wave has a higher energy utilization efficiency than the exponential wave, and the electrochemical corrosion in the bipolar processing chamber is lower. The pulse width and frequency determine the processing time, and the pulse energy contains the electric field strength and processing time, so their influence on the processing time is a comprehensive performance of many basic electrical parameters. In addition, the rise time of the pulse waveform also has an important impact on the PEF processing effect. There is a certain correlation between the above influencing factors. For example, the conductivity of the processing medium determines the equivalent impedance of the processing chamber, and the equivalent impedance affects the pulse waveform parameters output by the pulse power supply; for square waves In other words, the difference in load impedance leads to the difference in pulse rise time. Therefore, when analyzing differences in processing effects, the processing parameters, processing medium characteristics, and processing unit characteristics should be specifically considered.

Application of low-temperature plasma surface treatment equipment in cardiovascular stents and intraocular lenses

Application of low-temperature plasma surface treatment equipment in cardiovascular stents and intraocular lenses

Application of low-temperature plasma surface treatment equipment in cardiovascular stents and intraocular lenses: The urinary catheters and infusion sets in interventional instruments with low-temperature plasma surface treatment equipment have been introduced before. The biocompatibility and material bonding performance have been greatly improved, which can effectively reduce the actual clinical application of interventional instruments. The accident rate in the application. Therefore, what is the use of low-temperature plasma surface treatment equipment technology in implantable medical devices? This article mainly introduces two typical cardiovascular stents and intraocular lens devices. The processing technology of the low-temperature plasma surface treatment equipment improves the uniformity and durability of the cardiovascular stent drug coating: Almost all implantable biomaterials and related devices can be directly used in the human body, so they must have biocompatibility, such as cardiovascular stents and other materials that directly contact the blood must also have blood compatibility, so they will be used in the cardiovascular system. The surface of the stent is coated with a drug coating. The use of low-temperature plasma surface treatment technology can improve the bonding ability between the stent and the film. The main method is to use low-temperature plasma surface treatment technology to perform plasma treatment on the stent, which can improve the wettability of the stent surface and increase the adhesion. Make the medicinal film more uniform and firm. The treatment technology of the low-temperature plasma surface treatment equipment improves the hydrophilicity of the intraocular lens and effectively solves the postoperative inflammation problem: PAM intraocular lens is a new type of soft material with good diopter and flexibility, and its surface is highly viscous, can produce strong adhesion to the posterior capsule, and can effectively promote the migration and proliferation of lens epithelial cells. Reduce the occurrence of posterior capsule turbidity. However, the PAM material is highly hydrophobic and easily adsorbs bacteria and cells, resulting in postoperative inflammation. In order to improve the reliability of the intraocular lens and prevent inflammation, all current low-temperature plasma surface treatment equipment adopts the low-temperature plasma surface treatment process, and the corresponding process modification is used to increase its surface energy and improve its infiltration performance.
