(1) The working principle of plasma surface cleaning machine
①Plasma surface treatment refers to the process of physical or chemical action of non-polymeric inorganic gases, such as Ar, N2, O2, H2, etc. Plasma on the surface of the material. Involved in the surface reaction are excited state molecules, free radicals and ions, but also includes the role of plasma radiation ultraviolet light.
(2) the composition of the vacuum plasma cleaning machine structure
①Control unit: Nowadays, plasma cleaners mainly have four kinds of control units: fully automatic control, semi-automatic control, PC control, and LCD touch screen control, while the control unit mainly consists of power supply, control system, control buttons and operation display, etc.
② Vacuum chamber: Vacuum chamber is the space used for cleaning objects, mainly quartz chamber and stainless steel vacuum chamber. Because of its internal vacuum sterilization and anti-bacteria and plasma cleaning method, the cavity pressure has certain requirements, so it is necessary to use a better material cavity for configuration.
③ Vacuum pump: the main source of power for plasma cleaning machine is the vacuum pump, the main role is to vacuum the air in the vacuum chamber to dry, to achieve a vacuum environment, and then the plasma cleaning. Vacuum pumps are mainly divided into dry pumps and oil pumps. The dry pump mainly with electricity as the power source, while the oil pump uses gasoline or diesel as the power source.
(3) rotary spray type plasma surface treatment machine rotation
① DC motor: fast rotation speed, about 3000 rpm;
② Stepper motor: moderate rotation speed, about 2500 rpm;
③Hollow motor: Slightly slower rotation speed, 1800-2000 rpm
