The environment in the car interior has an important influence on people's physiology and psychology. Blue skies, green lawns, and clean streets can make you feel good. Similarly, the quality of the air inside the car, the comfort of the seats, and the cartoon appearance of the car can add to your good mood while driving. Car interior plasma processing manufacturing technology, the application of plasma cleaning machine can improve the printing mill resistant adhesive, car interior trim which are described below, the car interior includes air conditioning wind device, a steering wheel, dashboard, seating systems, airbags, seat belts, carpet, GPS, DVD, instrumentation, sensors, antenna, etc. Various, complex composition, including a variety of polymer plastics, metals, semiconductors, rubber, silicone, leather, circuit boards and so on. These materials have poor surface performance and are prone to problems in coating, bonding and printing. In order to facilitate coating and printing, manual grinding was generally used in the past, which was not efficient and seriously affected the appearance of the interior decoration. In terms of putting an end to the glue, the use of hot melt glue and other high-grade glue costs high, can solve the problem of degumming to a certain extent, but can not guarantee a good effect, if the glue, it will affect the entire car brand in consumer reputation.   The energy of the particles in the plasma of the automobile interior plasma cleaning machine is generally between a few to dozens of electron volts, greater than the bond energy of the polymer material, fully able to break the chemical bonds of organic macromolecules, so as to produce new bond energy; But far lower than high-energy radioactive rays, limited to automotive interior manufacturing process material surface, will not produce wear, does not affect the performance of the matrix. After the plasma surface treatment, the car interior can effectively activate and clean the surface, improve the surface adhesion, is conducive to coating or printing, make the surface adhesion reliable and lasting.
