What does the gas path control of the low-pressure plasma equipment cleaning machine include

What does the gas path control of the low-pressure plasma equipment cleaning machine include: The low-pressure plasma equipment cleaning machine has requirements for the control of various functional gas circuits and the stability of the process gas, so what parts of the gas path control of the low-pressure plasma equipment cleaning machine are composed? The low-pressure plasma equipment cleaning machine is also called vacuum plasma surface treatment machine. The size and accuracy of the process gas flow rate controlled by the gas path has little effect on the plasma surface treatment effect. Therefore, the gas path of the low-pressure plasma equipment cleaning machine is controlled by the gas It is composed of pressure regulating and processing components, pressure reducing gauge with alarm output, vacuum solenoid valve, flow meter, etc. Let Chengfeng Zhizao give you a detailed introduction to help you increase your understanding. Air pressure adjustment processing device: The gas input from low-pressure equipment is generally process gas with relatively high cleanliness, so the basic structure of gas pressure regulating and processing components is mostly composed of pressure regulating valves and filters. Its main function is to control the air pressure within the required pressure range and filter the impurities that may be contained in the gas to ensure stable operation and keep the gas clean, such as a back-end flow meter. The gas pressure regulating and processing device commonly used in the existing plasma surface treatment machine can be divided into a combined type and an integrated type according to its structural characteristics. Secondary pressure gauge with alarm output: In order to monitor whether the air pressure of the equipment meets the working requirements in real time, a pressure gauge with alarm output function is set on the gas pressure regulating valve. When the pressure is too low, an alarm signal is output to ensure the normal operation of the equipment and the stability of the process gas. Vacuum solenoid valve: When the low-pressure plasma equipment cleaning machine is working, it needs to maintain the vacuum degree and the sealing of the vacuum chamber. Therefore, each gas path valve connected to the cavity must meet the requirements of vacuum sealing. We should choose the matching vacuum solenoid with gas path control. valve. In order to ensure stable operation of the low-pressure plasma surface treatment machine, vacuum solenoid valves are used to control one gas, and the vacuum solenoid valves selected are all two-position two-way. Flow meter: The air intake volume of the low-pressure plasma equipment cleaning machine is controlled by a flow meter. The principle is to control the air volume by adjusting the size of the vent valve. The equipment uses two flow scoring methods: air flotation flowmeter and mass flowmeter.

Explanation of vacuum surface plasma treatment equipment using vacuum pump set

Explanation of vacuum surface plasma treatment equipment using vacuum pump set

Explanation of vacuum surface plasma treatment equipment using vacuum pump set: In general, the vacuum pump set of surface plasma treatment equipment is used on a vacuum plasma surface treatment machine. The pumping speed of the vacuum pump set is one of the important factors that determine the working efficiency of the vacuum surface plasma processing equipment. The pumping speed mainly depends on the vacuum pump. The pumping speed, when the processed product size is large, the pumping pump group cannot be selected arbitrarily. In the case of a large-scale product to be processed, it is inevitable to use vacuum surface plasma processing equipment with a large cavity (above 80L) for product processing. At this time, if only one vacuum pump is used, the vacuuming speed will be slower. , The vacuuming time will be prolonged, which will affect the processing efficiency. Therefore, we are generally equipped with vacuum pumps for large-cavity vacuum plasma surface treatment machines to increase the vacuuming speed. The use of two or more vacuum pumps combined into a series of vacuum pumps can greatly increase the vacuuming speed. Generally speaking, the vacuum pump components used in vacuum surface plasma treatment equipment are divided into three categories, one is the rotary vane vacuum pump plus Roots pump oil pump group; the other is the dry vacuum pump + Roots pump dry type Pump set; there is also a mechanical pump set consisting of molecular pumps and molecular pumps. Large-cavity vacuum surface plasma treatment equipment needs to use vacuum pumps, and the choice of vacuum pumps is also very particular.

Atmospheric pressure plasma cleaning machine can also be used to clean components on washing machines and induction cookers: The surface treatment technology of atmospheric pressure plasma cleaning machine seems to be a kind of high-tech, applied to high-precision fields, but it is not the case. With the improvement of people's quality of life and material quality, more and more daily necessities are Adopt plasma surface treatment technology to improve durability and improve product quality. Washing machines, induction cookers, dishwashers, range hoods, etc. are all things that we often come into contact with in our daily lives. For example, many people have the experience that the handle of the washing machine will fall off after a period of use, which greatly affects the experience of use. Due to the insufficient adhesion between the PP handle and the washing machine body, in daily use, if the atmospheric pressure plasma cleaning machine surface treatment technology is used, the washing machine handle and the washing machine body can be activated, and the distance between the PP handle and the washing machine body will be improved. The fastness and durability. Today, Chengfeng Zhizhi mainly introduces the application of plasma technology in washing machines and induction cookers. Necessity for the application of atmospheric pressure plasma cleaner surface treatment technology in the household appliance industry: Washing machines, induction cookers, and range hoods all belong to the home appliance industry. The home appliance industry is characterized by a fast update rate. Each batch of products uses a relatively large amount and uses different materials. There are high requirements in terms of material combination, process cost optimization, long-term durability of materials, and durability. The conventional method is to use different adhesives or flame surface treatment process to increase the bonding strength of the material and improve the adhesion of the surface ink and the printing quality. However, when the surface of the material to be bonded or printed is not cleaned, and there are contaminants that are invisible to the naked eye, the long-term stability of the bonding agent and the printing quality of the bonding layer may be reduced, resulting in completeness after a period of use. Invalidate. The plasma surface treatment process can simplify the production process, reduce manual cleaning using solvents, and even eliminate primers, save material and labor costs, make the process more environmentally friendly, and the surface treatment quality is more stable. Illustrate the application of atmospheric pressure plasma cleaning machine surface treatment on PP cleaning machine handle and induction cooker stainless steel bracket. The PP handle of this utility model can clean and activate the release agent, and improve the firmness and durability of the PP handle before bonding with the washing machine. sex. Plasma surface treatment is performed before the stainless steel bracket of the induction cooker and the composite heat-resistant glass are bonded to improve the bonding performance and reliability of the silicone and stainless steel. The stainless steel stent has not undergone plasma surface treatment, the dyne liquid is hydrophobic, and there are hidden dangers in the bonding quality. The stainless steel bracket processed by the atmospheric pressure plasma cleaning machine has significantly improved surface wettability and the bonding quality is guaranteed. The above is the application example of plasma surface treatment process in the home appliance industry.

Atmospheric plasma cleaning equipment low temperature plasma coating modified PVDF sulfonic acid membrane

Atmospheric plasma cleaning equipment low temperature plasma coating modified PVDF sulfonic acid membrane

Atmospheric plasma cleaning equipment low temperature plasma coating modified PVDF sulfonic acid membrane: In recent years, membrane technology has the advantages of high energy efficiency, high separation capacity, high selectivity, and relatively low cost. It is competitive in various industries and has been widely developed. The current application areas include acid recovery, salt manufacturing, food desalination, and process Wastewater desalination, organic synthesis, etc. Polyvinylidene fluoride (PVDF) is a copolymer of fluorine-containing vinyl monomers. Its high molecular weight can reach millions. Compared with other commercial polymer membrane materials, it has excellent weather resistance, thermal stability, chemical stability and Excellent mechanical properties. PVDF forms double bonds through alkalization to graft styrene monomer, and then sulfonates to introduce active groups. The cation exchange membrane prepared by this process has high ion exchange capacity and good mechanical strength. However, commercial products based on polystyrene are not Homogeneous membranes and alloy membranes often need to add mesh to increase the overall strength of the membrane. In terms of oxidation resistance, the PVDFgPSSA homogeneous membrane is better than the first two commercial membranes, which fully reflects the excellent characteristics of PVDF as a polymer membrane skeleton, but the selective permeability of the prepared membrane often cannot meet the requirements of industrial use. Therefore, it is necessary to modify the membrane with atmospheric plasma cleaning equipment. Common methods for PVDF separation membrane modification include plasma modification, blending modification, chemical modification, etc. of atmospheric plasma cleaning equipment. Compared with the blending modification, although the modification conditions are easy to achieve, the inorganic nanomaterials are easy to agglomerate in the film casting solution, resulting in uneven distribution in the PVDF membrane and reducing the effect of inorganic material modification. In contrast, plasma modification has wide applicability. The modification can uniformly act on the entire PVDF film surface. The plasma modification depth is tens of nanometers, which will not cause major damage to the internal structure of the film. The plasma of the atmospheric plasma cleaning equipment can cause a series of physical and chemical reactions such as cross-linking and initiating grafting on the surface of the PVDF membrane. The surface of the membrane becomes denser and smoother after coating and graft modification, which can effectively improve the barrier of the PVDF sulfonic acid membrane to chloride ions. However, the surface of the film is etched due to excessive irradiation, and the selective permeability of the film is reduced.

How does the atmospheric rotary plasma cleaning machine distinguish between independent and online equipment

How does the atmospheric rotary plasma cleaning machine distinguish between independent and online equipment: There are three ways to distinguish atmospheric jet plasma cleaning machines in the industry. Previously, Chengfeng Zhizao introduced to you that it can be divided into direct injection and atmospheric rotary plasma cleaning machines according to whether the spray gun rotates or not. There are small partners for independent and online There are doubts about the method of distinction, so let’s introduce it today. Atmospheric rotary plasma cleaning machine has the characteristics of simple structure and convenient installation. It can perform surface treatment on plastic, rubber, metal, glass, ceramics, paper and other materials. It has been widely used in printing, packaging, electronics, automotive and other industries. So, what we call an independent online type, how are multiple spray guns and single spray guns classified? Have you ever been confused when choosing? I believe this article will help you. Independent atmospheric rotary plasma cleaners and online atmospheric jet plasma cleaners are distinguished according to whether they are connected to the assembly line or automatically. Atmospheric rotating plasma cleaning machine, namely a set of plasma generator and plasma spray gun. The upper part of the ordinary spray gun will have a device hole, and the user can process the device jig according to the need, and arbitrarily match it on the assembly line. Atmospheric jet plasma cleaning machine (in-line type), which is designed according to the processing purpose, production capacity, production line and process characteristics of the customer's products, and can be directly installed on the assembly line. In most cases, it is customized according to customer requirements. In addition, according to the number of spray guns supported by the plasma generator, the atmospheric plasma equipment can also be divided into a single spray gun atmospheric jet plasma cleaning machine and a multi spray gun atmospheric jet plasma cleaning machine. The single-jet atmospheric jet plasma cleaning machine is a plasma generator (host) with a nozzle. The power adjustment is directly on the host, and the operation is relatively simple. The power adjustment range of each manufacturer is different, and the general rated power is 600~1000W. The multi-nozzle atmospheric rotary plasma cleaning machine is actually composed of multiple plasma generators (hosts), each plasma generator corresponds to a spray gun, and the power and flow adjustments are concentrated on a control panel. Supply equipment according to user requirements, which can be operated manually or through man-machine interface.
