Plastic products and rubber molds use low-temperature plasma cleaning machine in the operation of power requirements
　　Plasma cleaning machine is a cleaning method that relies on the "activation" of substances in the "plasma state" to remove surface stains. It belongs to the dry cleaning in the electronics industry. In the process, a vacuum pump is required to create a certain vacuum condition to meet the cleaning requirements. Let's take a look at the operation process and precautions of the plasma cleaning machine.
1. The requirements for the power supply of the low-temperature plasma cleaning machine during operation are: AC 220V/380V frequency is 50/60Hz, and also 3/12.5kw. Which configuration to choose depends on the requirements, and the power supply should be connected before starting. After the equipment is in operation, there should be a smooth running sound, and the green indicator light is usually on to show that the equipment is operating normally. If the yellow fault light is on, the operation should be stopped for maintenance.
Second, when using the low-temperature plasma cleaning machine for plastic products and rubber molds, pay special attention to the red warning light. When the equipment is running or shaking frequently, the red warning light is always on. At this time, press the reset button to observe the equipment immediately. If there are still abnormalities, immediately stop the operation of the equipment, and then perform fault inspection to avoid damage to the equipment.
Third, plastic products and rubber molds should be cleaned regularly when using a low-temperature plasma cleaning machine, and the power must be disconnected before cleaning, and then the cavity and electric control box can be opened, and pay attention to cleaning in accordance with the specifications required by the instructions. In addition, many low-temperature plasma cleaning machine cavities are of external annular electrical level, so the internal cavity is not easily polluted.
　　 Plasma cleaning The plasma required for plasma cleaning is mainly generated by specific gas molecules in special occasions such as vacuum and discharge, like low-pressure gas glow plasma. The main process includes: first send the workpiece to be cleaned into the vacuum chamber to be fixed, start the vacuum pump and other devices to start vacuuming and exhaust to a vacuum of about 10Pa; then introduce the gas for plasma cleaning into the vacuum chamber (depending on the different cleaning materials, The selected gas is also different, such as oxygen, hydrogen, argon, nitrogen, etc.), and the pressure is maintained at about 100Pa; a high-frequency voltage is applied between the electrode in the vacuum chamber and the grounding device to cause the gas to be broken down and pass the glow The light discharge ionizes and generates plasma; after the plasma generated in the vacuum chamber completely covers the workpiece to be cleaned, the cleaning operation starts, and the cleaning process will last from tens of seconds to several minutes.
