The plasma cleaning machine uses a new high-tech technology to use plasma to achieve effects that cannot be achieved by conventional cleaning methods, so as to complete cleaning, coating and other purposes. Its structure is mainly divided into three major parts, namely the control unit, the vacuum chamber and the vacuum pump. The domestic plasma cleaner control unit is mainly divided into four modes: semi-automatic control, fully automatic control, PC computer control, and LCD touch screen control. The principle of plasma cleaning is mainly to rely on the "activation" of the active particles in the plasma to achieve the purpose of removing stains on the surface of the object. In terms of reaction mechanism, plasma cleaning generally includes the following processes: inorganic gas is excited into a plasma state; gas phase substances are adsorbed on the solid surface; adsorbed groups react with solid surface molecules to generate product molecules; product molecules resolve to form a gas phase; The residue is free of appearance. Gas pressure control is one of the important parameters to ensure the normal operation of the plasma cleaning machine. Common gas pressure reduction includes gas cylinder pressure reducer, pneumatic pressure regulator and pipeline throttle valve: Cylinder pressure reducer Cylinder pressure reducer is a device that decompresses high-pressure gas in a gas cylinder to low-pressure gas. The process gas used by the plasma cleaner is mostly bottled high-pressure gas. In order to ensure the process stability and the working stability of each gas circuit element, the high-pressure gas is generally reduced to 0.2-0.4MPa through a gas cylinder pressure reducer. Pneumatic pressure regulator Pneumatic pressure regulating valve is an important equipment for pneumatic control. Its function is to control the external compressed gas at the required working pressure and keep its pressure and flow stable. Whether it is a vacuum plasma cleaning machine or an atmospheric plasma cleaning machine, a pneumatic pressure regulator will be installed when the gas is input. In order to ensure the cleanliness of the gas, a gas filter assembly can be installed during use. In order to check the gas pressure conveniently, a pressure gauge can be installed on the pressure regulating valve or a pressure regulating valve with a pressure gauge can be selected. If you need to provide under-pressure alarm, you can also choose a pressure gauge with alarm output function or install a pressure switch. Pipeline throttle Pipeline choke valves are generally used in atmospheric plasma cleaning machines, and the pressure and flow control can be achieved by adjusting the size of the vent through its pressure regulating needle valve. Most of the common pipeline throttle valves are quick-connect fittings and are relatively small in size. Yangzhou Guoxing is a high-tech company integrating R&D, production and sales.
