What are the characteristics of automated or semi-automated plasma surface treatment equipment

What are the characteristics of automated or semi-automated plasma surface treatment equipment

What are the characteristics of automated or semi-automated plasma surface treatment equipment: At present, automation technology has been widely used in various fields such as industry, agriculture, and military, achieving the goal of reducing manpower and improving efficiency. With the development and progress of PLC, the vacuum low-pressure plasma surface treatment machine continues to develop in the direction of automation and intelligence. The intelligent control and operation also allow more people to choose automatic plasma surface treatment equipment. Vacuum plasma machines can be divided into two types: semi-automatic and online. On-line low-pressure vacuum plasma machines have greatly improved automation and are one of the automated plasma surface treatment equipment. In fact, semi-automatic and online plasma equipment are controlled by PLC. The PLC and the touch screen communicate data through communication. The common features of the two plasma equipment are: high data collection accuracy, visual alarms, and maintenance. Convenient, low failure rate, high safety, convenient control logic modification, less connection lines, small size, and high reliability. Compared with semi-automatic plasma equipment, the line-type automatic plasma surface treatment equipment adds servo drives and motors, and adds photoelectric switches, proximity switches, axis limit switches and other components. At the same time, the control logic is also more complex than manual and semi-automatic devices, so , In the choice of PLC, the performance of the selected PLC is better than the semi-automatic plasma device, and the experience of using the equipment is also better. The semi-automatic and online automatic plasma surface treatment equipment controlled by PLC is used, and the operation is performed on the touch screen interface. The touch screen can be used to set and monitor the input and output values ​​of analog quantities such as discharge power, and can flexibly modify and set process parameters according to the processing object. There are two control modes, manual and automatic, on the touch screen. (1) Manual control interface: The manual interface can independently operate and control the vacuum pump, break valve, flapper valve, one-way air valve, two-way air valve, RF power supply, etc. (2) Automatic control interface: Under automatic control, we can set relevant process parameters in advance and save them as engineering recipes. After the installation is complete, just put it into the product, select the engineering formula, and press the start button. The above is mainly part of the semi-automatic and on-line automatic plasma surface treatment equipment and the characteristics of the two operating modes.

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

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.

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.
