Plasma cleaning machine surface cleaning activation uniformity is improved

Plasma cleaning machine surface cleaning activation uniformity is improved

Plasma treatment of plastic surfaces can effectively pretreat surface activation before gluing, printing or painting. Similarly, ceramics, glass and other materials can also be treated by isoionization. Industrial oxygen is often used as a process gas for plasma treatment, hence the name: oxygen plasma. And the atmosphere is called atmospheric plasma. The effects may last only a few minutes or even months, depending on the type of material that needs to be treated with plasma. Plasma treatment is a surface modification technology which uses corona discharge to change the surface properties of materials. After corona treatment on the surface of the material/object, it will be guaranteed to bind to the printing ink, paint and binder. Its purpose is to optimize the bonding properties of polymer substrates. The low surface energy of polymer substrates usually results in poor adhesion of inks, glues and coatings, and the high surface energy of these materials. Corona treatment is widely used in plastic film, extrusion, automobile, medicine and other industries. In order to obtain adhesion, the surface energy of the matrix must be greater than or equal to the material surface energy of the polymer used. Surface energy of solid materials and requirements for polymer surface treatment. Plastic materials often need to be bonded to metal or other plastic materials, or simply printed on the plastic surface. For this to work, a liquid binder or ink must be used to wet the surface of the material. Corona treatment and plasma treatment are needed here. Lubricity depends on a special property of the surface: surface energy, often called surface tension. Surface energy: A unit of measurement of surface energy, like surface tension, expressed in mN/m. The surface energy of a solid substrate directly affects the wettability of the liquid on the surface. The wettability can be proved by measuring the contact Angle. The contact Angle is the Angle between the tangent line of the contact point and the horizontal plane of the solid surface. How to improve the uniformity of plasma cleaning machine: 1. Surface wettability; 2. The wettability of the surface can help us distinguish good and bad wettability; 3. With the increase of liquid surface tension, the surface energy of solid substrate increases, and the better its wettability is, the smaller the contact Angle is. 4. In order to form an appropriate combination of liquid and substrate surface, the substrate surface energy should be within the liquid tension range of about 2-10Mn /m; 5. When a droplet is installed on a smooth solid surface, the droplet will spread to the substrate. If it is completely wet, the contact Angle is almost zero. Conversely, if the wetting is local, the resulting contact Angle is balanced between 0 and 180 degrees.

Why cooling water should be used in vacuum plasma surface treatment process

Why cooling water should be used in vacuum plasma surface treatment process

Process cooling water is a commonly used temperature control medium in industrial production. Its application is very wide. According to the types of use, it is mainly divided into dust-free workshop cooling, process equipment cooling, production process cooling, etc., and the application of vacuum plasma cleaning machine surface treatment can be summarized as process equipment cooling. Many people may think, plasma cleaning machine is not the use of low temperature plasma equipment, why will be used in the process of cooling water, and how can it be used correctly? So let's look at it. 1, plasma cleaning machine process cooling water application: (1) the electrode plate of cooling vacuum plasma cleaning machine: Vacuum plasma cleaning machine produced by plasma temperature is very low, but in use process, if you use a larger power or processing time is too long, can appear electric plate temperature, and plasma cleaning machine is also commonly deal with some of the products is more sensitive to temperature, this is where, according to the requirement of the user by cooling electrode plates in order to achieve the temperature stability of cavity in the purpose of the requirements. (2) Plasma generator cooling: The plasma generator of the plasma cleaning machine is the core component of the equipment. Generally, the use of small plasma cleaning machine is smaller, and the heat generated by the plasma generator itself is smaller, and the method of air cooling is generally chosen. The large plasma cleaning machine is the use of large output power of the plasma generator, the work of its own heat is also very large, in order to ensure the stability of the use of equipment, prolong the service life, the use of process cooling water temperature removal method to cool. (3) Vacuum pump cooling: Vacuum pump in the process of use without lubricating oil cooling, between the mechanical structure and produced a very high friction temperature, such as vacuum pump in the case of no cooling work, there will be rotor or screw locked, resulting in scrap. Therefore, vacuum pump needs real time cooling in use, the method adopted is to use process cooling water cooling. In order to reduce the noise of the motor and better protect the motor, the local dry pump in the design will generally choose the water-cooled motor, and the process cooling water is also needed for real-time cooling. 2, plasma cleaning machine process cooling water application: (1) Process cooling water of plasma cleaning machine: The process cooling water used by the plasma cleaning machine mainly has two sources, the supply of cooling water and the circulating water supply at the client end. For large plasma cleaning machines, independent cooling water units are required to protect the equipment. (2) General requirements of process cooling water: The cooling water temperature of plasma cleaning machine is generally controlled at 20~50℃, the pressure is generally between 0.3~ 0.5Mpa, and the flow rate is generally between 2~7SLM according to the actual needs. According to the practical application, the value range of operation parameters should be determined. (3) Real-time monitoring and control of process cooling water: All the parts that need to be cooled are key parts. If the temperature is too high or the pressure is insufficient, the products will be scrapped and the equipment parts will be damaged. Therefore, real-time monitoring is very important. In general, the plasma cleaning machine cooling water pressure and flow monitoring is completed by the water flow switch, the water flow switch is divided into mechanical and quantitative, need to be applied in series to the intake pipe, when the pressure or flow is too small, the output signal, complete the alarm function of the equipment. Generally, independent water flow switch is installed at the entrance of each temperature control component to ensure its stability and reliability. By installing a temperature sensor on each part, the chiller signal output, each part comes with a temperature sensor signal output, select the specific implementation method, so as to realize the temperature alarm. In practical application, in order to ensure the stability of the operation of vacuum plasma surface treatment equipment, a variety of methods are usually used at the same time.

What are the factors that cause abnormal discharge of vacuum plasma cleaning machine

What are the factors that cause abnormal discharge of vacuum plasma cleaning machine

Why the discharge of the vacuum plasma cleaning machine is abnormal? Please operate the following operations accompanied by professional personnel. The core components of RF plasma cleaning machine are RF power supply and matcher. Because the matcher can not work normally, there may be a normal power start and no discharge in the cavity. 1. Matcher fault description: (1) Air capacitance is only: Failure reason: the air capacitor in the operation of friction conductive impurities, causing local short circuit, friction caused by the rotor shaft damage, can not be adjusted normally. (2) Failure of imported transistor: Failure reasons: the air capacitor moving plate shaft is damaged, the air capacitor can not work normally, the RF output impedance can not be adjusted, the transistor is broken down, etc.; In the process of use, improper adjustment of the initial value of the matcher, too long matching time or unstable glow discharge in the chamber of the vacuum plasma cleaner will also cause damage to the transistor. 2. Matters needing attention in daily use of matcher: (1) Check the insertion place of the needle regularly in the vacuum chamber to prevent serious oxidation and fracture. (2) confirm that the electromechanical plate of vacuum plasma cleaning is placed correctly and there is no error in sequence; If the number and spacing of the electrode plate need to be adjusted during use, it is necessary to confirm the automatic matching state of the matcher. If the matching time is long, the initial value needs to be adjusted. (3) Confirm the initial value of the matcher regularly. Long-term use may lead to deviation of the initial value, which needs to be confirmed regularly and adjusted according to the actual situation. (4) If there is serious initial deviation, it is necessary to confirm whether the inside of the pair and the air capacitor blade are misplaced and whether there is a ignition phenomenon. If there is a ignition, it should be dealt with in time. The fixed gas capacity blade and the air capacitor actuator blade basically coincide when the volume is adjusted to the maximum; If there is a burning phenomenon, confirm whether the blade is burned out. If the burned position can be polished before use, the distance between the blades is too close, there will be burning phenomenon. If the capacitor cannot be adjusted, the matcher can be opened and the capacitor can be adjusted manually to confirm whether the blade capacitor can rotate normally. We should pay attention to whether the transmission part of the motor and the air capacitor does not rotate. If it is stuck, we should report it for repair in time. If there is a slip between the gear and the shaft, we can handle it by ourselves first. 3. Other matters (1) The matcher can be operated for a long time, and attention should be paid to observation and cleaning at ordinary times. To regularly check the pair of internal air capacitor area, open the cover, see if there is any air capacitor friction produced by impurities deposition, if there is, to clean with clean cloth + alcohol, because impurities are usually conductive material, can not be blown with gas, so as to avoid the occurrence of ignition and local control short circuit. (2) when the vacuum plasma cleaning machine matcher failure occurs, immediately confirm the placement of electrode plates, the placement of pin male female head, shielding box inside connection (if there is a bad contact, whether conducting strip in contact with the outer wall, whether too close), the determination of the initial value of verifier, interior is clean, the air capacitor mismatch and fire, air condenser is rotation (slip), drive motor can work normally, the RF power output, whether all wiring for short circuit, etc. If there is a burning odor in the pairing device or the above problem cannot be solved, please contact a professional in time. (3) The service cycle of the internal accessories of the matcher can not be clearly determined, which is related to the use environment, product treatment, proper use, etc., and the main reason may be short circuit or burn caused by impurities in the matcher.
