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.

The application of plasma automatic cleaning machine processing circuit board LED bonding packaging technology
The application of plasma automatic cleaning machine processing circuit board LED bonding packaging technology: Printed circuit boards, printed boards, PCBs, etc. are also called printed boards. The printed circuit board is prone to problems such as unclear printing, blurred printing, easy falling off of ink or non-staining of the printed circuit board during the printing process. The main reasons for this phenomenon are: first, the green paint surface of the circuit board is not clean, with oil stains, sweat stains, particles and other dirt; second, the ink quality is poor, and the amount of ink is insufficient, which has little effect. Third, the squeegee is not sharp enough or is blurred due to improper operation during the screen printing process. LED is more and more favored by people because of its high luminous efficiency, low power consumption, health and environmental protection (no ultraviolet, infrared, no radiation), protection of eyesight, long life and other advantages, and is known as the 21st century. new light source. In the packaging process LEDLED will produce pollution and oxidation. The bonding colloid between the lampshade and the lamp holder is not strong enough, and there are tiny gaps, air enters through the gap, and gradually causes the surface of the electrode to oxidize, resulting in the death of the lamp holder. The application of plasma automatic cleaning machine cleaning technology to clean LED packaging products does not pollute the environment, environmental protection and no pollution, which can solve this problem for LED packaging manufacturers. To solve the above problems. Mainly consider the following issues: whether the screen frame is in good condition, whether the image is clear, whether the ink scraping is correct, whether the screen frame is installed smoothly, whether the pressure is uniform, whether the screen frame height is balanced, and whether the ink is scraped and printed. Is the pressure appropriate. After the above conditions are met, the plasma automatic cleaning machine can be used to remove glue for the manufacturing process of soft and hard boards, high-frequency PTFE, multi-layer soft boards, etc. cleaning etc. It can solve the problem of unclear printing in PCB production. There are two main reasons for the weak bonding of fluorescent diodes. In the production process, the surface will inevitably be contaminated with many pollutants (such as organic substances, oxides, epoxy resin, particles, etc.), thus affecting the bonding effect. Light-emitting diodes are mainly made of difficult-to-stick plastics such as polypropylene and PE. This kind of plastic has the characteristics of low surface energy, poor wettability, high crystallinity, good non-polarity of molecular chain and fragile edge. In the bonding and packaging process, it is easy to cause the phenomenon of loose glue opening. Plasma cleaning of electronic parts: Because the plasma is positive and negative ions, the potential value of the plasma cleaning machine for electronic parts is zero. Avoid short circuit of circuit boards and damage to electronic equipment. Plasma automatic cleaning machine can provide ultra-precise circuit board cleaning, destaticization, dust removal, area activated plasma, and solve the problem of poor coating adhesion performance. Applying an ultra-thin, long-term stable selective anti-corrosion coating on the surface of electronic components can prevent electronic components from being corroded or damaged in extreme weather conditions. The plasma automatic cleaning machine equipment properly solves these two problems during the LED lamp plasma cleaning process. The plasma automatic cleaning machine acts on the surface of the material, and the positive and negative plasma generated can realize the physical and chemical cleaning of the surface of the LED material. Removal of contaminants down to the nanometer level, can remove surface contaminants such as organics, oxides, epoxy, particles, etc. When processing PP/PE and other plastics, the plasma generated by the automatic plasma cleaning machine pretreats the parts that need to be bonded through surface activation, surface corrosion, surface grafting, surface polymerization, etc., so that the non-polar materials are activated. This ensures reliable bonding and long-term sealing.

How is the use of plasma cleaners in the electronic screen industry?
How is the use of plasma cleaners in the electronic screen industry? Modern touch screens, LCD monitors and TV screens place high demands on the production process, because plastic parts must be treated with highly transparent scratch-resistant and anti-static coatings before bonding and assembly. Removing the impurities on the surface of the mobile phone screen and roughening the surface is conducive to improving the adhesion of the mobile phone screen coating and making it stick more firmly. Our conventional sandpaper polishing is obviously not suitable for use on the mobile phone screen, because it will Scratching the screen of the mobile phone will affect the use. Is there a way to remove the dirt on the surface of the screen and improve the roughness of the surface without affecting its aesthetics? The plasma treatment process of the plasma cleaning machine can be very solve this problem well. First of all, the plasma generated by the plasma surface cleaning machine contains electrons, ions and active free radicals. These particles are relatively easy to react with organic pollutants on the surface of the material to generate volatile and harmless gases, such as CO2 and water vapor. The whole reaction The process time is short, the efficiency is high, and the treatment effect is good. Secondly, when the plasma-treated mobile phone screen is being coated or sprayed, the active components in the plasma will quickly form chemical bonds with the material and the sprayed material. This bonding can greatly improve the strength of intermolecular bonding and make The film layer is difficult to loosen.        The COG assembly process of LCD is to mount the bare chip IC on the TO glass, and use the compression and deformation of the gold ball to make the pins on the ITO glass and the pins on the IC conduct. Due to the continuous development of fine line technology, it has developed to produce products with a pitch of 20um and a line of 10um. The production and assembly of these fine circuit electronic products have high requirements on the surface cleanliness of the TO glass, requiring the products to have good solderability, firm soldering, and no organic and inorganic substances remaining on the ITO glass to prevent the TO electrode terminals from being connected to the ITO glass. The continuity of the IC BUMP, therefore, the cleaning of the TO glass is very important. In the current ITO glass cleaning process, everyone is trying to use various cleaning agents (alcohol cleaning, cotton swab + lemonade cleaning) for cleaning, but due to the introduction of cleaning agents, it will lead to the introduction of cleaning agents. Therefore, exploring new cleaning methods has become the direction of efforts of various manufacturers. Through step-by-step tests, the principle of plasma cleaning is used to clean the surface of ITO glass, which is a more effective cleaning method.         In plasma cleaning of liquid crystal glass, the activated gas used is oxygen plasma, which removes oily dirt and organic contaminant particles, because oxygen plasma oxidizes organic matter and forms gaseous discharge. Its only problem is that it needs to add a static elimination device after removing the particles, and its cleaning process is as follows: Air blowing - oxygen plasma - in addition to static electricity.            The electronic industry's requirement for a high degree of automation requires the adoption of an online surface treatment process with high reliability, high production efficiency and treatment effect. The ultra-fine atmospheric plasma cleaning and plasma activation provided by the plasma process brings effective solutions to the electronics industry. Plasma treatment of the plastic viewing window section prior to antistatic and anti-scratch spraying on spray equipment. Due to the use of plasma cleaning technology, the surface energy of the material is increased, so the coating distribution is more uniform, the plasma cleaning machine not only creates an impeccable product appearance, but also greatly reduces the scrap rate in the production process.

Application explanation of low temperature plasma surface treatment technology characteristics of wide-width plasma cleaning machine:
Application explanation of low temperature plasma surface treatment technology characteristics of wide-width plasma cleaning machine: The surface treatment technology of the wide-width plasma cleaning machine can be matched with a variety of different post-processing processes, among which the typical post-processing includes printing, bonding, and painting. The low-temperature wide-width plasma cleaning machine is suitable for industrial applications in various fields. It can provide subsequent bonding, coating, and pre-printing treatment for different materials or composite materials, so that two different materials can be effectively and reliably combined together. The plasma surface treatment equipment for plasma cleaning, surface cleaning, activation and coating mainly provides pretreatment for bonding, painting, sputtering and other processes in the digital industry. The low-temperature plasma surface treatment technology is widely used in digital products for mobile phone casings, mobile phone keys, notebook computer casings, notebook keyboards, plastic products, etc. Widely used raw materials for printing, coating and bonding of polyethylene, polypropylene, polyvinyl chloride, polyester, polyoxymethylene, PTFE, vinyl, nylon, (silicon) rubber, plexiglass, ABS and other plastics Surface pretreatment of other processes. The shape, width, height, material type, process type, and need for online processing of these materials all directly affect and determine the solution of the entire surface treatment equipment. The main features of the low-temperature wide-width plasma cleaning machine: 1. High uniformity: atmospheric pressure plasma is a glow-type plasma curtain, which directly acts on the surface of the material. Experiments have shown that the processing uniformity of the same material at different positions is very high. This feature is useful for the next step in the industrial field. Coating, printing and other processes are very important. 2. Controllable effect: Atmospheric pressure plasma has three effect modes to choose from. One is to use argon/oxygen gas combination, which is mainly used for non-metallic materials and requires higher processing effect. The second is to use an argon/nitrogen combination, mainly for the metal area of ​​the product to be treated that cannot be treated. Due to the strong oxidation of oxygen, this problem can be controlled after replacing the nitrogen in this scheme. The third is the case where only argon is used. The surface modification can also be achieved by only using argon, but the effect is relatively low. This is a special case, and it is a solution adopted by a few industrial customers when a limited and uniform surface modification is required. 3. Safe and stable: atmospheric pressure plasma, also low temperature plasma, will not cause damage to the surface of the material. No arc, no vacuum chamber, and no harmful gas suction system, and it will not cause physical damage to the operator for a long time.

Plasma surface modification equipment treatment to improve the corrosion resistance of biological scientific research metals
Plasma surface modification equipment treatment to improve the corrosion resistance of biological scientific research metals: Surface modification of metal materials by biomedical chemical methods is a new type of new technology developed in recent years. This method is based on the following assumptions: the biologically active substances are directly attached to the metal substrate, and the macromolecular protein or enzyme-like organic polymer materials are introduced to the surface of the substrate, so that they have better biological activity and are more direct and effective. Once the metal materials in the organic matter are corroded, the corrosion products produced by the dissolved metal ions will cause adverse effects on the human body, so it must be controlled. Studies have shown that metal materials themselves will not cause allergies to the human body. However, the dissolved metal ions or dissolved ions in the form of metal salts combine with biological molecules or form abrasive dust, which may cause harm to the human body. In addition, the fracture of human metal materials is mostly caused by fatigue and friction fatigue, and these two factors are not simple factors, but are actually caused by corrosion fatigue, which is closely related to corrosion. In order to prevent the toxicity of metals in the body, improve the safety of metal materials, and prolong their service life, it is of great significance to study the corrosion of metal materials with plasma surface modification equipment in the field of biological science research. Some researchers have treated metal surfaces with NH3 and N2 plasmas to enter amino groups, which are then quaternized by reaction with methyl iodide, and then use the negatively charged anticoagulant heparin to form the quaternized amino groups on the metal surface. complexes, thereby immobilizing heparin on metal surfaces. The nitrogen groups formed on the metal surface can also be used to immobilize proteins, and the surface of most metal materials is immobilized by attaching a layer of hydrophilic macromolecular film. Under certain conditions, it will interact with [H] or H- to form hydroxyl (-OH), which adheres to the surface of the substrate, in this case APS (An1inopropyltriethox-ysi-lane) plasma, and then passes through glutaryl The action of acid aldehyde (An1inopropyltriethox-ysi-lane) can chemically bond proteins or enzyme isolates such as trypsin to the substrate surface. The method can fix biomolecules on the surface of metal, inorganic, non-porous and non-loose biological materials, so that the surface activity of the materials is greatly improved. Most of the metal substrates, such as Ti, Ti6Al4V, Co-Cr-Mo, TiTa30, etc., can be modified by plasma grafting of organic matter plasma surface modification equipment, so that biomolecules can be directly adsorbed on the surface. Artificial biomaterials used for transplantation, tissue culture or other purposes must have good biocompatibility with the biological environment. Currently, when developing biocompatible surfaces to adhere cells, the main focus is on the surface immobilization of ECM proteins and metal substrates, while techniques for surface modification of materials that do not require adherent cells, such as blood cells, are the fabrication of high Inert surfaces, such as fluorohydrocarbons, or biologically active molecules prevent cell fixation, or generate highly hydrophilic groups, etc. Most of the medical stainless steels commonly used in clinical practice now contain nickel elements. For example, the nickel content in medical 316l stainless steel is 10~14. As a potential sensitizer, the toxic effects of nickel ions in the human body due to corrosion, abrasion, precipitation, and accumulation can cause cell destruction and inflammatory responses. Similarly, cobalt and nickel elements in medical cobalt-based alloys also have greater sensitization. However, V and Al in titanium alloys are harmful to organisms. This makes the application of metal biomaterials limited to a certain extent. In order to enable the implanted metal biomaterials to fully exert their functions, they can be surface-modified by plasma surface modification equipment, such as using low-temperature plasma to graft polymer films on the surface of stainless steel, or using cobalt-based alloys. The TiO2 film grafted on the surface of the titanium alloy and the surface of the titanium alloy by the bioscience plasma grafting plasma surface treatment equipment can effectively prevent the precipitation of nickel ions and improve the effect of the ion precipitation of the abrasive products on the surface of the nickel-based alloy and the titanium alloy on the surrounding tissue of the implant. adverse reactions, greatly improving the safety of long-term use of biological implant materials.
