(Summary description)Introduction to Plasma of Vacuum Plasma Surface Treatment System (Encyclopedia) Introduction to plasma of vacuum plasma surface treatment system (Daquan):         The plasma surface treatment system we produce has produced atmospheric plasma, vacuum plasma surface treatment system and wide-format equipment series of treatment systems. With decades of experience and research results, the equipment runs trouble-free up to 99.9% and gives a powerful surface Cleaning and activation function. Vacuum plasma surface treatment system         Vacuum plasma surface treatment system plasma treatment surface:         Plasma treatment is used in the previous treatment steps, such as printing, bonding, spraying, painting or cleaning the coating and activating the surface. They are used to solve problems related to adhesion and wetting in many industries.         1. Introduction to plasma         Plasma is a state of existence of matter, usually in three states: solid, liquid, and gas, but in some special cases, it may also exist in the fourth state, such as substances from the surface of the sun and the ionosphere of the earth’s atmosphere. . This state of matter is called the plasma state, which is the fourth state of matter. The following substances exist in the plasma, and electrons are in high-speed motion; neutral atoms, molecules, and atomic groups (radicals) are in an activated state; ionized atoms and molecules; ultraviolet rays generated in the decomposition reaction of molecules; unreacted molecules and atoms And so on, but the substance is still neutral as a whole.         2. How to generate plasma         Various forms such as arc discharge, glow discharge, laser, flame or shock wave can transform gaseous matter under low pressure state into plasma state. For example, gas molecules, such as oxygen, nitrogen, methane, and water vapor, in a high-frequency electric field at low pressure, when the glow discharges, they will decompose accelerating atoms and molecules, so that the generated particles will be decomposed. Dissociate into electrons and positively and negatively charged atoms and molecules. The charged particles and electrons produced in this process gain high energy when they are accelerated in the electric field, and collide with surrounding molecules or atoms, so that the molecules and atoms are re-excited by the electrons, and they themselves are in an excited state. And ionic state, when the matter is in a plasma state.         3. Types of plasma in vacuum plasma surface treatment system         According to the temperature, it can be divided into two types: high temperature plasma and low temperature plasma.         According to the different chemical properties of the gas used when generating the plasma, from the perspective of the activity degree of the gas, the plasma can be divided into reactive gas plasma and inert gas plasma.         4. The effect of plasma on the surface of an object         In addition to gas molecules, ions and electrons, there are also atoms or groups of atoms (also called free radicals) that are excited by energy in the plasma of the vacuum plasma surface treatment system, as well as the light emitted by the plasma. Among them, the wave of The length and energy level play an important role when the plasma interacts with the surface of the object.         1) Free radicals such as radicals react with the surface of the object.         2) The effect of electrons on the surface of an object.         3) The effect of ions on the surface of an object.
