Advantages of plasma for ultra-precision cleaningAlmost all surfaces have subtle dirt that is invisible to the naked eye, which seriously affects the further treatment of the surface, such as bonding, printing, painting or coating. These fine impurities on metal, plastic or inorganic materials can be removed by plasma cleaning without the need for additional chemicals. In contrast to plasma coating or plasma etching, the surface of the workpiece is not removed or coated, but merely corrected.Ultra-precision cleaning of the exterior using atmospheric pressure plasma is the process of removing organic, inorganic and microbial exterior contaminants as well as strongly adhering dust particles. It's very efficient and very gentle with the treated appearance. At higher strengths, it can remove thin outer boundary layers, cross-link outer molecules, and even cut hard metal oxides. Plasma cleaning advances moisture and adhesion support a wide range of industrial processes, preparing the ex...

To check the adhesion of the coating, a mesh incision test is performed (specifications: DIN EN ISO 2409 and ASTM D3369-02). After painting, the paint layer of the plastic part is cut into a grid shape. Next, apply standard tape to the cut mesh, secure the tape and then abruptly tear it back off. If there is paint on the tape, it indicates that the adhesion of the paint is not good. The mesh is cut to show the adhesive strength of the paint layer on the plastic partTest inkMeasurement method for estimating surface energy: If the test ink accumulates in one place after being applied to the surface, the surface energy of the solid is lower than the surface energy of the ink, and if kept wet, the surface energy of the solid is equal to or greater than the surface energy of the liquid. By using a series of test inks with gradient surface energy, the total surface tension of a solid can be determined. However, this method cannot determine the polar and non-polar parts of the external ener...

Vacuum plasma cleaning machine system by the response chamber (vacuum chamber), high frequency plasma power supply and vacuum pump group (vacuum system), inflation system and automatic control system (touch computer +PLC multi-step process automatic control, full circuit detection) and other parts, plasma is a matter of existence. Also called the fourth state (usually material in solid, liquid, gas three states exist), such as the Earth's atmosphere in the ionosphere. Vacuum plasma cleaning system is the use of high voltage power supply under a certain pressure conditions to apply the gas to meet the energy, and then produce plasma, plasma condition there are the following substances: in the state of high-speed movement of electrons; Neutral atoms, molecules, and groups of atoms (free radicals) in an active state; Ionized atoms or molecules; The molecules, atoms, etc., do not react, but the substance still maintains a neutral state in general. The plasma moves at high speed under t...
