How to choose a better pipeline for conveying external gas from plasma vacuum plasma cleaner

How to choose a better pipeline for conveying external gas from plasma vacuum plasma cleaner

How to choose a better pipeline for conveying external gas from plasma vacuum plasma cleaner: The gas path is one of the basic components of plasma vacuum plasma cleaning machine gas path control and operation. If it is not selected properly, it will affect the effect of processing products and the service life of the equipment. Careful friends should be able to find that plasma vacuum plasma cleaning machine Almost all the external air pipes of the equipment are plastic air pipes. Why? In particular, what kind of material is better to choose? The air pipe of the plasma vacuum plasma cleaning machine for air path control and operation can be divided into two types: outer air pipe and inner air pipe. Of course, the outer air pipe is mainly responsible for the transportation of the outer air pipe, and the air pipes selected are generally made of plastic materials. What are the advantages of choosing this plastic tubing? What are the specific classifications? There are two types of plastic tubing commonly used for the outer tube of plasma vacuum plasma cleaners, namely PU tubing and PTFE tubing. In the industrial field, most of them use PU tubing, especially pneumatic control. In the plasma vacuum plasma cleaning machine, the PU tube is mainly used for the gas tube for conveying general industrial gas, the gas tube in the cylinder, and the gas tube for the control components. The use of PU pipes for external pipes has the following advantages: 1. It has good bending resistance and a small bending angle, which is convenient for use in pipe laying operations; 2. PU pipe has good wear resistance, pressure resistance and fatigue resistance; 3. PU pipes are more beautiful, light and flexible; 4. PU pipes have high cost performance and price advantages. Another type of plastic gas pipeline is PTFE tube, that is, polytetrafluoroethylene tube. In addition to some of the characteristics of the above-mentioned PU tube, PTFE tube also has a significant feature, that is, it also has better corrosion resistance. When the gas transported is a process When the gas is corrosive, it is necessary to use a PTFE tube as an external gas pipeline.

How to deal with the equipment power alarm when the surface plasma treatment equipment is processing

How to deal with the equipment power alarm when the surface plasma treatment equipment is processing

How to deal with the equipment power alarm when the surface plasma treatment equipment is processing: Power supply alarms appear on low-pressure vacuum plasma surface treatment equipment. Generally, the power supply alarms can be divided into the following two situations: power supply alarms and power reflected power alarms. Don’t panic when power alarms occur when using the equipment. The processing methods are roughly The same, easier to grasp. The root of the alarm problem lies in the power supply, and the power supply of the plasma surface treatment equipment is not what we usually call the power supply. In theory, it is a plasma generator. The two main reasons for power supply alarms are excessive power supply deviation and deviation of reflected power from the power supply. What should I do if the above-mentioned power alarm information appears in a concentrated situation? This problem is also of concern to many equipment users. First, look at the alarm interface that displays the power alarm information on the display. In fact, the solution includes six small steps: 1. First check whether the parameters of the low-pressure vacuum plasma device have been reset to zero. If so, we will reset it to manual mode, and then perform a test to see if it can work normally. 2. After checking the equipment parameters, the next step is to check whether the plasma of the low-voltage vacuum plasma equipment and the coaxial cable of the counterpart, the plasma control line and other wiring are normal (use a multimeter to measure and check whether the connection is Loose). 3. Next, you need to check whether there is any deviation in the initial position of the capacitor from the plasma generator panel of the low-pressure vacuum plasma equipment. If there is any deviation, you need to reset it. The power supply brand is different and the adjustment method is slightly different. 4. Check whether the power supply of the low-voltage vacuum plasma device is set correctly, and check whether the capacitor of the matcher is normal. 5. Check whether the plasma generator settings, feedback and reflection signals of the low-pressure vacuum plasma equipment are normal. Use a multimeter to measure and check whether the terminals are tightly pressed. 6. After troubleshooting the power supply and distribution box failure, first run to see if it has returned to normal, and then set it to automatic mode. The above is how to deal with the power alarm of the power supply of plasma surface treatment equipment.

What are the special features of the common gas path control layout of vacuum plasma machines

What are the special features of the common gas path control layout of vacuum plasma machines

What are the special features of the common gas path control layout of vacuum plasma machines: The stable and continuous control of the process gas is one of the factors to ensure the processing effect of the vacuum plasma machine. Chengfeng Zhizao introduced the composition of the gas path control to everyone. What is the common gas path control layout of the vacuum plasma machine? What is special about the composition of the air path, let us study together. 1. Commonly used gas path control layout form of vacuum plasma machine The gas circuit commonly used in vacuum plasma machines generally includes three main parts: two process gas controls, one air breaking control, and the other compressed air control, namely CDA control. 2. The components and characteristics of the gas circuit of the vacuum plasma machine: (1) The compressed air control part only needs a set of high-pressure gas, filter screen and output alarm pressure gauge, no other parts are needed; since CDA is the power gas of some components, only an alarm device is required when the gas pressure is insufficient. (2) The vacuum breaking part adds a large-caliber vacuum solenoid valve on the basis of the CDA control gas circuit. After the process operation is completed, the vacuum breaking gas is input into the vacuum chamber. Because the vacuum breaking gas is usually a high-purity gas, Therefore, no filter is installed in the partially broken air path. (3) The process gas is usually a high clean gas, and the filter is usually an optional component. The process gas control part mainly includes pressure regulating valve, filter, alarm, alarm output alarm meter, vacuum solenoid valve and quality controller. The process gas is generally two-channel, and multiple process gases can also be configured according to actual needs. (4) According to this kind of gas circuit arrangement, the air intake sequence is: first the filter delivers the gas to the pressure regulating valve, the pressure gauge outputs the gauge, and then passes through the vacuum solenoid valve and the quality controller in turn. The above are the common gas path control layouts and the characteristics of various components of vacuum plasma machines.

Plasma cleaning equipment manufacturers explain to you: the factors that affect the adhesive strength of adhesives

Plasma cleaning equipment manufacturers explain to you: the factors that affect the adhesive strength of adhesives

Plasma cleaning equipment manufacturers explain to you: the factors that affect the adhesive strength of adhesives          The size of the bonding strength is related to the composition of the adhesive, the structure and properties of the adhesive, the performance of the adherend, the surface condition and the operation mode during use. Adhesive strength refers to the adhesive strength on the unit bonding surface. The bonding strength mainly includes the cohesive strength of the adhesive layer and the adhesive strength between the adhesive layer and the bonded surface. The plasma cleaning equipment manufacturer will explain to you below. Factors that affect the adhesive strength of the adhesive.Composition composite coating (refers to a sprayed layer composed of two or more different materials. The material composition of the composite coating changes stepwise in the thickness direction of the composite coating. It is called a stepped composite coating. Plasma cleaning equipment is used and various surface treatment technologies are used. Combined application to improve the protective ability of the coating to the substrate) After the bonding material and curing agent are determined, the cold welding bonding strength is mainly related to the powder addition amount, curing agent addition amount, and toughening agent addition amount in its components. In addition, , The construction process and the substrate material, surface roughness and cleanliness also have a greater impact on the cold welding bond strength. (1) The influence of the amount of powder added Appropriate addition of powder fillers can reduce the shrinkage of the coating and eliminate internal defects, thus improving the bonding strength of the coating. However, the increase in the amount of powder will reduce the adhesive material in the coating and reduce the bonding strength. (2) The influence of the amount of curing agent added Insufficient curing agent is added, and curing is incomplete; if the curing agent is added too much, the brittleness of the coating will increase, and the residual curing agent will reduce the performance of the coating. Therefore, it is necessary to accurately calculate the amount of curing agent when developing cold welding composite materials. The curing agent has been prepared in proportion when the composite coating is sold. The user can calculate and weigh and add according to the proportion specified in the product manual, without the need for tedious calculations. (3) The influence of other factors Appropriate addition of coupling agents can improve the bonding strength; the addition of defoamers, anti-aging agents, and accelerators can only reduce the bonding strength, so the use must be strictly controlled. In addition, a certain degree of roughness and necessary cleanliness on the surface of the workpiece can improve the bonding strength; on the contrary, the surface with oil stains and rust will seriously reduce the bonding strength and even cause failure. Therefore, in order to improve the bonding strength, the following points must be paid attention to. ① The rough surface has a larger actual bonding area, which is beneficial to improve the bonding strength. Therefore, the bonding surface is better processed into a tooth-shaped surface. ② The proportion of the curing agent of the adhesive must be accurate, that is, it must be strictly weighed according to the proportion specified in the product manual. Too much or too little will affect the bonding strength. ③ The two components of the adhesive A and B must be mixed thoroughly, and the colors should be consistent. ④ The surface of the base metal must be as clean as possible, and there must be no oil stains and rust stains. ⑤ The ambient temperature during construction is better than 10°C, and the construction is not suitable if the ambient temperature is below 5°C. ⑥ During construction, the bottom layer must be repeatedly scraped to make the adhesive and the surface of the substrate fully wetted. ⑦ The curing reaction of industrial adhesives is relatively slow at room temperature. In order to improve the bonding strength and accelerate the curing reaction, the curing temperature can be increased. If possible, the curing can be used at 60~80~C, and the coating can be completely cured in 4~6 hours. The bonding strength between the cured coating and the substrate is gradually improved, and the bonding strength often continues to increase after being put into use.

What are the special requirements of the plasma generator for the cooling water of the process

What are the special requirements of the plasma generator for the cooling water of the process

What are the special requirements of the plasma generator for the cooling water of the process: Process cooling water is a commonly used temperature control medium in industrial production. It has a wide range of applications. Its application in plasma generators belongs to the cooling of process equipment. In fact, processed products are sensitive to temperature. Large plasma generators will generate a lot of heat when they work. Dry vacuum pumps will generate high temperatures after friction when they work. This is why we equip the equipment with process cooling water. What are the requirements and precautions for plasma generators that use process cooling water? Let's take a look. 1. Water source of process cooling water: There are two main sources of process cooling water used in the plasma generator, the cooling water supply source and the terminal circulating water supply. For large equipment, it is recommended to install a chiller separately to facilitate subsequent maintenance. 2. General requirements for the cooling water of the technological process: The cooling water temperature of the plasma generator should generally be controlled at 20~50°C, which can be adjusted according to actual needs; the pressure is generally 0.3~0.5MPa, and the flow rate is generally 2~7SLM. According to actual usage requirements, actual parameters need to be determined. 3. Real-time monitoring and control of process cooling water. All the parts that need to be cooled are key components. If the temperature is too high or the pressure is insufficient, the product will be scrapped and the equipment parts will be damaged. Therefore, real-time monitoring is very important. Once the requirements are exceeded, the production must be stopped immediately. Generally, the monitoring of the pressure and flow of cooling water is completed by a water flow switch. The water flow switch is divided into mechanical and quantitative types, which need to be used in series on the water inlet pipe. When the pressure or flow is too small, the signal is output to realize the alarm function of the device. Under normal circumstances, an independent water flow switch is installed at the entrance of each temperature control component to ensure stability and reliability. The method to realize the temperature alarm is to install the temperature sensor to each component, the chiller signal output, and each component has its own temperature sensor signal output. The specific implementation method is selected according to actual needs. In practice, in order to ensure the stability of equipment operation, multiple methods are often used at the same time. The above is the plasma generator's requirements for process cooling water and precautions for use.

Application of plasma surface cleaning machine to toys and other commodities

Application of plasma surface cleaning machine to toys and other commodities

Application of plasma surface cleaning machine to toys and other commodities: People’s living standards, health awareness and aesthetic concepts continue to improve. Consumers have higher and higher expectations for the purchase of daily necessities. Rational consumers must make comparisons in many aspects before purchasing. They must be economically applicable and satisfy the appearance The quality of printing and painting, the environmental protection of the production process, the application of new materials, and even the requirements for anti-fingerprint, hydrophobic, antibacterial or flame retardant functional coatings. In fact, plasma surface cleaning machine treatment has unique characteristics in these process solutions. ! Chengfeng Zhizao will give you an example today. Application of plasma surface cleaning machine processing technology in toy aircraft wings: The children's toys made follow high-level safety standards, and the types of adhesives and printing inks all have considerable quality requirements. The plasma surface treatment process can not only improve the surface adhesion of the material, but also make the production process safer and more environmentally friendly. The wing of a toy airplane needs reliable bonding. The surface tension of the wing base material is less than 40 dyne, and the surface tension is above 48 dyne to meet the bonding requirements. After the toy airplane wings are processed by the plasma surface cleaning machine, the surface tension value exceeds 60 dynes, which can fully meet the bonding requirements. Plasma surface cleaning machine processing swimming goggles: The inner layer of ordinary swimming goggles with better quality is generally treated with anti-fog, that is, an anti-fog coating is applied to the PC material. The plasma surface cleaning machine can remove the release agent and increase the adhesion of the anti-fog coating. Before the plasma surface treatment, the contact angle of the water droplets was 82.5 degrees, and the coating quality was not good. Plasma surface treatment is used, and the contact angle of water droplets is 11 degrees, which ensures the quality of the coating. The above are some cases of plasma surface cleaning machine processing technology applied in daily life.
