The three types of flat electrode structures of vacuum plasma equipment introduce those unknown secrets

The three types of flat electrode structures of vacuum plasma equipment introduce those unknown secrets

The three types of flat electrode structures of vacuum plasma equipment introduce those unknown secrets: This article introduces a new type of vacuum plasma equipment for the research of vacuum plasma discharge and surface modification of materials. The plate electrode is a commonly used electrode structure for vacuum plasma equipment, and it is divided into flat horizontal electrodes, flat vertical electrodes, and flat combined electrodes. When designing the electrode structure of vacuum plasma equipment, it is often necessary to fully consider factors such as the shape and size of the processing object, placement method and capacity requirements, product and material characteristics, and different processing purposes, so that the electrode structure design is more reasonable. Chengfengzhi makes it for you Three types of flat electrode structures are introduced in detail: horizontal electrode type of water plate, vertical electrode type of flat plate and combined electrode type of flat plate. The electrode structure of the flat-plate horizontal electrode vacuum plasma equipment: This kind of electrode structure is common. The area of ​​the metal electrodes between the layers is equal, and the plasma discharge is relatively uniform. A bracket can be placed between the electrodes, and the product to be processed can be placed on the bracket. The distance between layers can be adjusted. The electrodes can be punched or cooled by adding water. Except film, roll and powder products or materials that cannot be processed, other items are acceptable. The electrode structure of the flat vertical electrode type vacuum plasma equipment: This electrode structure cannot simply convert horizontal electrodes to vertical electrodes. It needs to fully consider the distance between the metal electrodes between layers, the uniformity of plasma discharge, the temperature control of the electrode plate, the placement of products or materials, etc., and the product There are usually two ways to place the electrode: add a clip or hook between the electrodes; add a clip and hook on the cart to handle items. The plasma discharge uniformity of this structure is better than that of a horizontal electrode. The electrode structure of the flat panel combined vacuum plasma equipment: Similar to products such as LEDs, PCBs, and metal guide frames, they are often placed in fixtures for plasma cleaning, using a flat-plate combined electrode structure. According to the size of the fixture and the production capacity, it can be designed into a processing space for multiple bins. The productivity of this structure is high, but the fixture needs to be grooved on both sides, and the intermediate product processing effect of the fixture is not as good as the upper part, and the plasma discharge uniformity is insufficient. The above is the introduction of the motor structure of the flat vacuum plasma cleaner. Chengfeng Zhizao recommends that you choose according to the shape, characteristics, and processing purpose of the product you need to process when you buy it.

What are the control valves often used in the process gas control of the vacuum plasma surface treatment machine

What are the control valves often used in the process gas control of the vacuum plasma surface treatment machine

What are the control valves often used in the process gas control of the vacuum plasma surface treatment machine: There are many types of gas channel control valves. The gas channel control valves widely used in vacuum plasma surface treatment machines can be divided into manual and automatic according to the operation mode. According to the control mode, they can be divided into pneumatic control valves and solenoid valves, such as According to the working pressure, it can be divided into vacuum valve and low pressure and medium pressure control valve. In the vacuum plasma surface treatment machine, the air path control mainly includes two parts: the process air path control and the vacuum path control. In the process gas control part, commonly used control valves include vacuum solenoid valves, check valves (check valves), and pneumatic ball valves. The following is a detailed introduction to the control valves commonly used in the process control of vacuum plasma surface treatment machines. Commonly used control valves for process gas control: Vacuum solenoid valve: It is necessary to ensure that the working vacuum in the vacuum chamber is within the design range, so the valve connected to the vacuum chamber must meet the requirements of high vacuum sealing, so vacuum solenoid valves are used for conventional process gas control. Since the process gas adopts single-channel control, the selected vacuum solenoid valve is two-position two-way. Pneumatic ball valve: Because the pneumatic ball valve has the characteristics of high vacuum sealing, corrosion resistance, and large diameter, it is used for air circuit control when the vacuum plasma cleaning needs to lead to a special monomer. Choose two-way or three-way, you can choose according to actual needs. Check valve: In the gas circuit control, the check valve is also called the check valve. It mainly plays a role in preventing the backflow of gas, protecting other equipment in the gas circuit control part, and preventing the confluence of reacting gases. Pay attention to the direction of the airflow when using it. There are many types of gas circuit control valves. Its normal operation needs to ensure its vacuum, air tightness and prevent gas backflow. It is very important to choose a suitable control valve. The above is the introduction of the process gas control valve commonly used in the vacuum plasma surface treatment machine, I hope it will be helpful to everyone!

What are the advantages of domestic plasma cleaning equipment plasma equipment

What are the advantages of domestic plasma cleaning equipment plasma equipment

What are the advantages of domestic plasma cleaning equipment plasma equipment: Plasma cleaner is also called plasma cleaner, or plasma equipment surface treatment. It is a new high-tech technology that uses plasma to achieve effects that cannot be achieved by conventional cleaning methods. Plasma is a state of matter, also called the fourth state of matter, and it is not the common three states of solid, liquid and gas. Apply enough energy to the gas to ionize and become a plasma state. The "active" components of plasma include: ions, electrons, atoms, active groups, excited nuclides (metastable states), photons, etc. Plasma cleaners use the properties of these active components to treat the surface of the sample to achieve cleaning, coating and other purposes. As far as the current plasma cleaning equipment is concerned, the plasma equipment has reached the domestic and foreign technical level. Of course, this still depends on the strength of the plasma equipment manufacturer. At present, in China, there are still few with independent R&D and production capabilities. For the development of China, a powerful economic country, many high-tech equipment technologies can reach the level of integration with foreign countries. So in the Chinese market, which plasma cleaning equipment is better? This is also a problem considered by many manufacturers of plasma equipment. Let's talk about products first.

Plasma equipment cleaning machine plasma treatment PMMA/MMT composite micron fiber for immobilization of laccase

Plasma equipment cleaning machine plasma treatment PMMA/MMT composite micron fiber for immobilization of laccase

Plasma equipment cleaning machine plasma treatment PMMA/MMT composite micron fiber for immobilization of laccase: Laccase is a kind of copper oxide, which promotes the oxidation of various aromatic materials while reducing oxygen in the solution. The specificity of laccase and its ability to degrade many pollutants indicate that it has great potential in the field of sewage treatment and bioremediation. Fixing laccase on a water-insoluble substrate can improve its stability and can be reused. Electrospinning is a novel and universally applicable method for preparing nano or micro fibers. The ultra-high specific surface area and porosity of nanofibers make microfibers an ideal material for enzyme immobilization substrates. The surface of electrospun PMMA micron fibers has a microporous structure, which further increases the specific surface area of ​​the micron fibers. Montmorillonite (MMT) is one of the silicate minerals. It has a unique layered one-dimensional nanostructure. Each unit cell consists of two silicon-oxygen tetrahedral layers and aluminum ( Magnesium) oxygen (hydrogen and oxygen) octahedron structure. The thickness of each layer is about 1nm, has a large specific surface area and a diameter-to-thickness ratio of up to 20, and has high rigidity, and it is not easy to slide between layers. The upper and lower surfaces of montmorillonite are all oxygen atoms, and the layers are only combined by van der Waals forces, so the connection force is very weak. Therefore, water or other polar molecules can easily enter the interlayers, causing the layer bonds to break, and the layer spacing Increase, resulting in directional expansion of the crystal lattice. Therefore, montmorillonite is an expansive clay mineral, and its swelling degree is related to the types of exchangeable cations. DMMA/MMT composite micron fiber is prepared by high-voltage electrostatic spinning method, and its surface is treated with plasma equipment cleaning machine plasma technology to improve the immobilization rate of laccase. Micropores are evenly distributed on the surface of the original fiber. This micropore has a certain effect on the adsorption of laccase. The micropores on the surface become blurred after the original laccase is adsorbed. This may be because the immobilized laccase will affect the surface The micropores are covered. After plasma treatment with a plasma equipment cleaner, the micropores on the fiber surface become larger and free oxygen groups are now available, which makes the fiber surface easy to combine with water molecules and improves the hydrophilicity of the fiber surface. The fiber after plasma treatment by the plasma equipment cleaner has greatly increased the adsorption of laccase. This is because the hydrophilicity of the fiber surface is increased, which is beneficial to the combination of laccase and the fiber. The electrospun PMMA/MMT composite micron fiber was successfully used for the adsorption of laccase after plasma treatment. The plasma treatment of the plasma equipment cleaning machine greatly improves the hydrophilicity of the fiber, thereby promoting the adsorption of laccase. Infrared analysis showed that laccase formed a chemical bond with MMT in the fiber.

What to do if the atmospheric low-temperature plasma instrument does not discharge

What to do if the atmospheric low-temperature plasma instrument does not discharge

The normal operation of the atmospheric low-temperature plasma instrument plays a decisive role in the UPH (production capacity) of each plant. Once the atmospheric low-temperature plasma instrument fails, if it cannot be eliminated in time, it will bring huge economic losses to the enterprise. How to deal with non-discharge equipment? The atmospheric low-temperature plasma instrument has the advantages of high cleaning efficiency, online production, and environmental friendliness. With the development of the times, the industry has higher and higher quality requirements. Cosmetic packaging, electronics, automobiles, new energy and other industries need to use atmospheric low-temperature plasma meters to improve product quality. Compared with the vacuum plasma cleaner, the atmospheric low temperature plasma instrument has a relatively simple mechanical structure. In order to ensure production efficiency, the operator must have a certain operating ability. The common troubleshooting methods are as follows: There are two situations where there is no plasma ejection when starting up: 1. The LCD panel does not display, and the red LED indicator does not light up; Answer: Please check whether the power supply is normal and whether the power plug is in poor contact. 2. The LCD screen displays, and the red LED indicator flashes quickly (5 times per second); Countermeasures: Check whether the high-voltage line is off or damaged, and if it is damaged, replace it; If there is no problem with the high-voltage wires, it may be that the motherboard is faulty, please contact the supplier as soon as possible. 3. The red LED indicator light flashes slowly (1 time per second) after the startup and operation stop suddenly after a while: Countermeasures: Check whether the pressure of the decompression gauge is normal. The inlet pressure of the atmospheric low temperature plasma instrument is 86~106KPa. If the pressure is too low or too high, adjust the pressure of the decompression gauge to this range. Check whether the air pipe connection is leaking and whether the air pipe is damaged. If it is damaged, please replace the leaking joint with the damaged air pipe.

Which automobile plastic parts can be sprayed with small plasma spraying equipment

Which automobile plastic parts can be sprayed with small plasma spraying equipment

Which automobile plastic parts can be sprayed with small plasma spraying equipment: Plastic products not only reduce the weight of the car body, reduce energy consumption, but also ensure function and safety; through different surface treatment processes, the comfort and decoration of the products are continuously improved. Before silk-screening, bonding, coating and other processes on plastics, the traditional surface treatment methods are manual polishing, flame burning and spraying primer. Now let’s discuss the application of small plasma spraying equipment in the surface treatment of automotive plastic parts. . Small plasma spraying equipment is widely used in the surface treatment of automotive plastic parts. Plastic parts account for more than 1/3 of the total automotive materials, most of which are composite materials, such as PP, ABS, PA, PVC, EPDM, PC, EVA, respectively Processed into bumpers, dashboards, central control panels, door panels, protective panels, engine covers, sealing panels, lamps, shockproof pads, etc. The composite material is made of a combination of multi-physical materials, which can complement each other's strengths and obtain excellent properties that a single material cannot achieve, such as polypropylene (PP) + glass fiber (GF20), polypropylene (PP) + EPDM rubber (EPDM) + Talc (TD20), etc., are widely used in automotive interior parts. Materials similar to PP, EPDM, and ABS+PC have low surface energy and poor wettability, which will affect the quality and surface performance of the screen printing, bonding, coating, and flocking of the material. After using small plasma spraying equipment to process the above materials, it is found that under the action of plasma active particles, the surface performance of the material has been greatly improved, and the tearing ability has also been greatly improved. From the analysis of the results, it can be seen that there are two main reasons: 1. The plasma discharge generated by the small plasma spraying equipment can introduce hydrophilic groups on the surface of the material, such as the hydroxyl group (OH) of the phenol group, the carboxyl group (-COOH) and the carbonyl group (C=O) of the carboxylic acid, thereby improving the surface of the material. The wettability greatly improves the adhesion and bonding strength of the substrate surface. 2. The plasma generated by the small plasma spraying equipment promotes the opening of the molecular bonds of the material, and the cross-linking effect and low molecular weight contaminants are removed. The surface of the material forms a clean and strong contact surface layer, which can also improve the bonding of the contact surface. Strength and binding power. Automotive plastic parts of various shapes and materials can be surface treated with small plasma spray equipment for flocking plastic parts. Not only can the quality control of flocking be guaranteed, but also adhesives that are harmless to the human body and the environment can be selected to reduce the health risks of the operator. Use vacuum plasma spray equipment to perform surface treatment before covering plastic door panels made of polypropylene (PP) + talcum powder (TD20) to enhance the bonding performance of the water-based polyurethane adhesive and plastic parts and improve the tearing force. Plastic products after surface treatment by small plasma spraying equipment, their bonding strength and bonding strength are the same as the electrode structure of the vacuum chamber of plasma surface treatment, discharge vacuum degree, gas type and ratio, gas flow size, treatment time, power supply, etc. The parameters are closely related; the plasma surface treatment has a certain timeliness, so the relevant production should be completed as soon as possible.
