Plastic Plasma Surface Treatment Plasma processor manufacturers

 Difficult to stick plastic mainly refers to polyethylene (PE), polypropylene (PP) and other polyolefins and polytetrafluoroethylene (PTFE), fluorinated ethylene propylene (FEP) and other fluorine-containing plastics. Such plastics usually have other polymer materials do not have the advantages, such as low cost plastic polyolefin such as PE, performance, ease of processing into a variety of profiles, it is widely used in daily life; and PTFE, commonly known as plastic king is a very good overall performance plastics, has excellent heat resistance, cold resistance and chemical resistance, are widely used in the electronics industry and a number of cutting-edge fields. However, due to difficult to stick the plastic surface is chemically inert, if not through a special surface treatment with a universal adhesive bonding difficult. The main form of low-temperature plasma surface treatment at 3.1 surface etching plasma effect, some of the chemical bonds broken material surface, forming small molecule product or oxidized to CO, CO: and so on, these products are pumped evacuation process go, and the material surface becomes uneven, the roughness increases. 3.2 In the plasma surface activation effect, difficult to stick the plastic surface appears part of the active atoms, radicals and unsaturated bond, these active groups and active particles in the plasma react in contact new active group. However, the material with active groups will be subject to influence by oxygen or molecular chain segment movement, so that the surface active groups disappear, so the surface-active material plasma processing has a certain timeliness. 3.3 surface grafting plasma surface modification of materials, due to the activity of plasma particles on the surface of the molecule and the surface molecular chains to produce new radicals, double bonds and other active groups, surface crosslinking ensues graft reaction. 3.4 surface when using the plasma polymerization reactive gas, will produce a layer of polymeric material is deposited on the surface layer, the presence of sedimentary layers help to improve the bonding capacity of the material surface. At low temperature plasma difficult to stick plastic processing, the role of these four forms occur simultaneously. Therefore, the low temperature plasma gas can be used, will be divided into reactive and non-reactive low-temperature plasma low-temperature plasma. Low-temperature plasma surface modification of materials has been widely used in electronics, machinery, textile, aerospace, printing, environmental protection and biomedicine.
