The jet-type atmospheric low-temperature plasma treatment machine is composed of a plasma generator, a gas delivery system, and a plasma plasma spray gun. The plasma generator generates high-voltage and high-frequency energy to generate low-temperature plasma in the glow discharge that is activated and controlled in the nozzle steel pipe. The plasma is sprayed to the surface of the workpiece with the help of compressed air. When the plasma meets the surface of the object to be processed, Chemical effects and physical changes have occurred, the surface has been cleaned, and hydrocarbon contaminants such as grease and auxiliary additives have been removed. According to the material composition, the surface molecular chain structure has been changed. Free radical groups such as hydroxyl and hydroxyl have been established. These groups can promote the adhesion of various coating materials and are optimized for adhesion and paint applications.
The jet-type atmospheric low-temperature plasma processing machine is also called plasma processing equipment. The core components are the RF power supply and the matching device. It may encounter the situation that the power supply starts normally but the cavity does not discharge. That is because the matching device is not working properly. Let me share some The little common sense about the matcher is for reference only: 1. Elucidation of the fault of the matching device. The air capacitor is damaged. The cause of the fault: the air capacitor conflicts with conductive impurities during operation, causing a partial short circuit; the conflict causes the rotor shaft to be damaged and cannot be properly adjusted. The reason for the failure of the imported transistor: It is related to the damage of the air capacitor moving plate shaft, the air capacitor cannot work normally, the RF output impedance cannot be adjusted, and the transistor breakdown; in the process of use, the initial value of the matcher is adjusted incorrectly, and the matching time is too long or The unstable glow discharge in the vacuum chamber can also cause damage to the transistor. 2. Precautions for daily use of the matching device. Regularly check the male and female pins in the vacuum chamber to avoid severe oxidation and fracture. Acknowledge that the electrode plates are placed correctly and there is no order error; if you need to adjust the number and spacing of the electrode plates during use, you must recognize the automatic matching condition of the matcher. If the matching time is longer, you need to adjust the initial value. Regularly acknowledge the initial value of the matcher. Long-term use may cause the initial value to deviate. It needs to be acknowledged regularly and adjusted according to the actual situation.
Brief introduction of jet-type atmospheric low-temperature plasma treatment machine ★The jetted plasma stream is neutral and uncharged, and can be used for surface treatment of various polymers, metals, rubber, PCB circuit boards and other materials; ★Improve the bonding strength of plastic parts. For example, after PP material is processed, it can be increased several times. After most plastic parts are processed, the surface energy can reach more than 68 dyne; ★After plasma treatment, the surface performance is lasting and stable, and the retention time is long; ★The dry method has no pollution, no waste water, and meets environmental protection requirements; ★On-line processing can be run on the production line to reduce costs.
