(Summary description)The answer is that ozone is at work. The basic principle of ozone generation during plasma discharge is that oxygen molecules are decomposed into oxygen atoms in the low-temperature plasma gas formed in the discharge reactor, and then ozone molecules are formed through the three-body collision reaction, which also takes place in the ozone decomposition reaction. Ozone, chemical molecular formula for O3, also known as triatomic oxygen and superoxygen, because of its fishy taste and named, room temperature can be reduced to oxygen. Compared with oxygen, it is soluble in water and easily decomposed. Ozone consists of an oxygen atom carried by an oxygen molecule, which determines that it is only temporarily stored. The oxygen atoms that carry them are used up by oxidation, and the rest combine to form oxygen into a stable state, so there is no secondary pollution of ozone. If the gas we introduce contains oxygen, a small amount of ozone will be produced during the reaction. It is because of the production of ozone, we can sometimes smell a bad smell when using the plasma cleaning machine, which is also the reason that the plasma cleaning will produce a bad smell. Plasma cleaning machine, also known as plasma surface treatment instrument, is a new high-tech technology, the use of plasma to achieve conventional cleaning methods can not achieve the effect. Plasma is a state of matter, also known as the fourth state of matter, does not belong to the common solid liquid gas three states. By applying enough energy to a gas, it can be ionized into a plasma state. The "active" components of plasma include ions, electrons, atoms, active groups, excited nuclides and photons, etc. The plasma cleaning machine USES the properties of these active components to treat the sample surface, so as to achieve the purpose of cleaning. Conditions for plasma production: sufficient reaction gas and pressure, reaction products must be able to hit the surface of the cleaning object at high speed, and sufficient energy supply. The resulting substances must be volatile micromixtures so that they can be pumped away by vacuum pumps. The capacity and speed of the pump must be large enough to rapidly remove the by-products of the reaction and to replenish the gas required for the reaction.
