The 10 major functions of plasma surface treatment equipment in the manufacture of auto parts

The 10 major functions of plasma surface treatment equipment in the manufacture of auto parts: In recent years, plastics have been used more and more in the automobile manufacturing industry. At present, the amount of plastics used by well-known foreign automobile manufacturers generally accounts for 10-15% of automobile materials, and some even exceed 20%. Whether it is automotive exterior parts, interior parts, car headlights, weather strips, or functional and structural parts, the shadow of plastic products can be seen everywhere. The continuous improvement of the hardness, strength and tensile properties of industrial plastics has promoted the development of the automotive plasticization industry. Using plastic instead of steel can greatly reduce the weight of the car itself, thereby reducing fuel usage and lowering emission standards. Before painting, the plasma surface treatment machine equipment can perform surface activation cleaning on the protective rod of PP/EPDM composite before painting. As an independent component, the shock absorber not only beautifies the appearance of the car, but also has an important impact on the safety protection and aerodynamic performance of the car. In order to reduce fuel consumption and fuel costs and achieve low emission standards, lightweight, dense and corrosion-resistant plastic materials have gradually become the main materials for automobile bumpers, and the amount of plastic materials has increased year by year. To ensure the internal and external quality of the product, the surface treatment of plastic needs to be better than that of steel. Through a variety of data comparisons, the plasma surface treatment machine equipment has a good treatment effect, can be processed online, has low cost, energy saving and environmental protection, and is currently an ideal treatment process in this field.

Plasma stripping cleaning machine stripping etching process processing glass cover cleaning

Plasma stripping cleaning machine stripping etching process processing glass cover cleaning: Today, when 5G communication technology is fully moving towards the 5G era, high-frequency 5G signals have put forward strict requirements on the signal transmittance of mobile phone materials. China's 5G commercial network will be put into operation in many cities in China. Since metal casings will block 5G signals, manufacturers are switching to non-metallic materials such as plastic, glass, ceramics, sapphire and other non-metallic materials to make mobile phone casings. In order to make the shell more beautiful and more powerful, various coating processes have followed the trend, and the manufacturer's stripping requirements for plasma stripping cleaning machines are becoming more and more strict. Glass cover coating, also known as glass cover spraying, is suitable for the 5G industry, covering mobile phone cover coating, glass cover, display coating, protective layer, optical material coating, etc. Like makeup, paint can be used both to change your image and to make yourself more beautiful. It can make the glass cover and bottom plate more beautiful, and also has the functions of anti-fingerprint, anti-glare, anti-ultraviolet, acid and alkali resistance, and anti-oxidation. For the glass case of the mobile phone, in order to realize the function and decorate the glass case on the front and back of the mobile phone, a variety of coating processes are used. Coating processing is a very delicate process, which has high requirements on the cleanliness of the surface of the substrate. Any tiny dirt, oil stains, fingerprints, water vapor, solid particles, etc. will cause trachoma, discoloration, and oil spots on the coating. and other adverse phenomena. When the quality of the coating is not good, it is necessary to reprocess the defective coating by stripping. At present, the plasma stripping cleaning machine process and stripping solution are still the mainstream of stripping. Compared with the stripping solution, the plasma etching stripping process has its advantages mainly in three aspects, namely the advantages of plasma surface treatment. Plasma stripping cleaning machine stripping is an environmentally friendly process, without any waste gas, waste liquid and other pollutants. Compared with expensive stripping solutions, stripping of plasma processors can only consume electricity. A single plasma surface treatment machine, once per hour, greatly reduces the cost. The stripping of the plasma stripping cleaning machine is through the plasma glow reaction to ensure that the high-density, low-temperature plasma obtains a better surface activation effect. Clean the surface organic matter, resin, dust, oil, impurities, etc., and increase the surface energy. The surface of the material is roughened by modification, the surface protrusion after etching is increased, and the surface area is increased. The oxygen-containing polar groups, such as hydroxyl, carboxyl and other active molecules are introduced. A plasma cleaning machine is used for strip surface treatment, which can effectively remove defective coatings. It is used for the rework of defective industrial coatings such as glass cover plates, display touch screens, protective sheets, optical materials, electronic circuits, etc. For spraying processes such as AF, AS, AG, AR, etc., a plasma pretreatment device (generally low temperature and atmospheric pressure rotary spraying, etc.) is used to perform fine pretreatment cleaning, etching and activation on the surface of the substrate, and a very thin high tension can be obtained. The surface of the coating is conducive to the strong bonding force of the spraying liquid and the uniform thickness.

What are the causes of plasma catheter etching?

Plasma treatment technology is an emerging technology that developed rapidly in the 20th century, and has become a key technology in some important industries (such as microelectronics, semiconductors, materials, aerospace, metallurgy, etc.) , surface modification and other aspects of the application has created great economic benefits. The advantages of plasma treatment are many, the most important is that the treatment effect is limited to the surface without affecting the bulk properties. The surface of the catheter is cleaned, disinfected and sterilized by the plasma method. For the silicon treatment on the surface of the catheter, an organic solvent needs to be used, which will cause pollution to the environment. The material used in the oxygen plasma method is oxygen or air, which does not pollute the environment. It is an environmentally friendly new surface treatment. method. There was no significant difference in the infrared absorption of these major groups before and after sample treatment. The energy of the active particles in the plasma is generally several to a dozen eV, while the chemical bond energy in the rubber material molecules is mostly 3-6 eV. The energy of the particles in the plasma is greater than or equal to the bonding energy of the rubber material molecules, so the bonding bonds can be broken to form new bonds, but because its energy is much lower than that of the radiation, the plasma treatment only occurs on the surface of the substrate, while the Does not damage the substrate. Etching-deposition is a pair of opposite and simultaneous chemical reactions that the plasma acts on the surface of the material to be treated. The oxygen plasma treats the film wrapped on the surface of the catheter, and its chemical structure is similar to that of the rubber material. This is practically beneficial as it avoids harmful side effects due to surface treatments. The contact angle of the catheter surface was 84° without treatment, 67° after treatment with oxygen plasma, and decreased by 17° after treatment, indicating that the hydrophilicity of the catheter was better improved. After the surface of the urinary catheter is treated by oxygen plasma, etching occurs, the surface is clean, and a small amount of hydrophilic groups are generated, thereby improving its hydrophilic performance and reducing the contact angle. After the oxygen plasma treatment, the burrs on the surface of the catheter are passivated, the coarse particles become smaller, and the surface becomes smooth. This is consistent with the measurement results of the surface contact angle. Causes of catheter etching include physical sputtering as well as chemical etching. The very low content of charged active species in the plasma plays an extremely important role in the surface treatment of materials. Since the moving speed of electrons is much greater than that of ions, the surface potential of the material placed in the plasma is negative relative to the plasma potential (called the drift potential. The high-speed electrons excite, ionize or break the reactive molecules into free radical fragments, The positive ions continuously bombard the surface of the material to be treated, which significantly affects the chemical reaction that occurs on the surface. Chemical etching is due to the fact that the energy of the active particles in the plasma is close to or slightly greater than the bond energy of the chemical bonds of the molecules of the material being processed. The closeness of this energy level makes the chemical bonds of the catheter material molecules exposed to the plasma easily broken, or the formation of small molecules from the matrix, or the formation of new chemical bonds, resulting in cross-linking, or the formation of free radicals. The effect of chemical etching is not obvious; from the results of SEM analysis, the effect of physical sputtering is obvious; the measurement results of contact angle suggest that physical sputtering and chemical etching work at the same time. Therefore, it can be inferred that the role of physical sputtering in the initial stage of oxygen plasma treatment on the catheter surface is dominant. Oxygen plasma treatment of the surface of the catheter leads to its surface etching, which makes the surface smooth and hydrophilic. The chemical structure of the surface film formed by the oxygen plasma treatment does not change much, so as to avoid the side effects of the urinary catheter in practical application.

What aspects can be improved by using the functional characteristics of the plasma plasma cleaning machine?

What aspects can be improved by using the functional characteristics of the plasma plasma cleaner? Plasma plasma cleaning machine uses high-energy particles and active particles in the plasma to achieve the purpose of removing dirt on metal surfaces through bombardment or activation reaction. No chemical reagents are used in the plasma cleaning process, so it will not cause secondary pollution. The cleaning equipment is highly repeatable, so the operating cost of the equipment is relatively low, and the operation is flexible and simple, which can realize the whole or some parts of the metal surface. And the cleaning of complex structures; some surface properties can be improved after plasma cleaning, which is helpful for subsequent processing applications of metals. Plasma plasma cleaners are widely used in cleaning, etching, modification, coating and activation. Plasma surface treatment. Through surface treatment, the wettability of the surface of the material can be improved, thereby improving the properties of the material such as coating, enhancing the adhesion and cohesion of the material and removing organic pollutants. The ultrasonic cleaners that appear on the market now cannot achieve the effect of modification. They can only clean some visible objects on the surface. Due to various defects in the process, high-tech products such as plasma cleaners have been derived. More and more industries are using plasma cleaning machines. Through plasma cleaning machines, surface modification, cleaning, and product performance improvement can be achieved, which greatly reduces the defect rate caused by the product in the process, thereby improving product quality and reducing production costs, etc. In the process of metal surface cleaning, the collision between electrons and atoms or molecules can generate excited neutral atoms or radicals (also known as free radicals), which are activated with pollutant molecules. Reacts to remove contaminants from the metal surface. When the electrons are transported to the surface cleaning area, they collide with the pollutant molecules adsorbed on the cleaning surface, which will cause the pollutant molecules to decompose and generate active free radicals, which will help to trigger further activation reactions of the pollutant molecules; moreover, the mass Very small electrons move much faster than ions, so the electrons reach the surface earlier than the ions and give the surface a negative charge, helping to initiate further activation reactions. In general, the number of free radicals in the plasma is more than that of ions, which is electrically neutral, has a relatively long life, and has a relatively high energy. During the cleaning process, the pollutant molecules on the surface are easily combined with high-energy free radicals to generate new free radicals. These new free radicals also live in a high-energy state, which is extremely unstable and easily decomposes itself and transforms into smaller free radicals. At the same time, new free radicals are generated. This process will continue until it is decomposed into stable and volatile simple small molecules, and finally the pollutants are released from the metal surface. In this process, the main role of free radicals It is manifested in the energy transfer during the activation process. In the process of combining free radicals with surface dirt molecules, a large amount of binding energy will be released, and the released energy is used to promote new activation reactions of surface dirt molecules. Power, which is conducive to the more thorough removal of contaminants under the activation of plasma. Using the features of the plasma cleaner can improve the following areas: ①plasma plasma cleaner changes wettability (also known as wettability). The wettability of the surface of some organic compounds has a great influence on the adhesion of pigments, inks, binders, etc., as well as the electrical properties such as flashover voltage and surface leakage current on the surface of the material. The measure of wettability is called the contact angle. ②plasma plasma cleaner enhances adhesion. The bond strength of the material to the adhesive can be enhanced by treating some polymers and metals with plasma-activated gases. The reason may be that the crosslinking of the polymer surface strengthens the adhesion of the boundary layer; or the introduction of dipoles during the plasma treatment improves the adhesion strength of the polymer surface; it may also be that the plasma treatment eliminates the polymer The dirt layer on the surface improves the adhesion conditions. Corona treatment also has the same effect. ③Plasma plasma cleaner strengthens the adhesion of polymer to polymer. For example, glass fiber reinforced epoxy resins have 233% enhanced adhesion to vulcanizates after plasma treatment with helium. After the polyester tire cord is plasma treated (eg NH3), the adhesion strength to the rubber is greatly improve

The principle of using the major functional characteristics of plasma in different industries

The principle of using the major functional characteristics of plasma in different industries Low-temperature plasma + photocatalysis technology refers to filling the plasma reactor with TiO2 catalyst. When the high-energy particles generated by the reactor decompose organic pollutants into small molecules, these substances are further oxidized and decomposed into inorganic molecules under the action of the catalyst. Small molecules to achieve the purpose of purifying and separating waste gas. The photocatalyst and the plasma discharge are interrelated. The catalyst can change the properties of the plasma discharge, so that the discharge can produce new active substances with stronger oxidizing power; while the plasma discharge will affect the chemical composition, specific surface area and catalytic performance of the catalyst. structure, improve its catalytic activity, and greatly improve the efficiency of low-temperature plasma + photocatalytic technology to purify VOCs. The combined technology is more suitable for treating organic waste gas with large air volume and low concentration, and has the advantages of low operating cost, fast reaction rate, and no secondary pollution. Plasma surface modification uses the high-energy active particles in the plasma to bombard the surface of the material, giving the surface new properties. Since it only acts on the surface, the original bulk properties of the material remain unchanged. It should be pointed out that plasma has no requirements on the base material, and can be used for surface modification of metal materials as well as insulating materials. Plasma cleaning is the process of cleaning a product to improve its ability to print or bond. The purpose of plasma cleaning is to remove organic surface contaminants. Plasma treats the surface of your product to accept printed adhesives or inks. Usually on Teflon or plastic, plasma surface modification actually changes the surface of the material, leaving free radicals and making it stick to the glue or ink When the plasma interacts with the surface of the object to be cleaned, on the one hand, the plasma or plasma-activated chemically active substances are used to chemically react with the contaminants on the surface of the material, such as the oxidation reaction between the active oxygen in the plasma and the organic matter on the surface of the material. . The plasma interacts with the organic dirt on the surface of the material, and decomposes the organic dirt into carbon dioxide, water, etc. for discharge. When using plasma to modify or clean materials, low-temperature plasma is usually used, and the gas temperature does not exceed 100°, which is macroscopically speaking; but microscopically speaking, when the plasma and the material surface occur, During chemical or physical reactions, if the energy is concentrated in a local area, once the material is processed for too long, it may cause damage to the surface of some materials. Plasma etching technology for fiber structure analysis is the earliest application of plasma treatment in the textile industry and has become a mature technology. Another application is the modification of textile materials, using plasma to modify the surface of textile materials. , graft polymerization and plasma polymerization deposition, etc., to change the surface hydrophilic (hydrophobic) of textile materials, increase adhesion, and improve printing and dyeing properties.
