  Among the equipment in the pre-treatment and cleaning link produced by the plasma cleaning machine manufacturer Zhenyi Co., Ltd., there is a low-temperature plasma cleaning machine equipment. Then when we use a low-temperature plasma cleaning machine, why do we explain that the low-temperature plasma as a cleaning process only involves the surface and does not Affect the performance of its matrix? Before explaining this situation, the editor Rogen wants to love you and take everyone to understand low-temperature plasma:
 

Why low temperature plasma as a cleaning process only involves the surface and does not affect the performance of the substrate?
 

  The energy of the particles in the low-temperature plasma is generally about a few to tens of electron volts, which is greater than the bond energy of polymer materials (a few to tens of electron volts), which can completely break the chemical bonds of organic macromolecules to form new bonds; but It is much lower than high-energy radioactive rays, so the low-temperature plasma only involves the surface of the material and will not affect the performance of the substrate.
 

  In fact, for a low-temperature plasma in a non-thermodynamic equilibrium state, electrons have higher energy, which can break the chemical bonds of the surface molecules of the material, and improve the chemical reaction activity of the particles (larger than thermal plasma), while the temperature of neutral particles is close to At room temperature, these advantages provide suitable conditions for the surface modification of heat-sensitive polymers.
 

  Under these favorable conditions, low-temperature plasma is undoubtedly a good choice as a cleaning process. As a plasma cleaning machine manufacturer and a spray coating equipment manufacturer, we have already developed more in the process of coating and cleaning.
