(Summary description)With the continuous improvement of plastic processing and modification technology, the application field is expanding rapidly. Different application fields require more and more plastic surface decoration, material protection, improvement of adhesion and other properties, but the corresponding surface properties of various plastic materials are obviously different due to their different structures and components. Various surface treatment technologies and products adapted to different applications emerge as The Times require. Due to the characteristic low surface energy of most plastics, the adhesive property is low in nature, and many treatment methods, such as decoration, printing, spraying, etc., cannot be directly applied, and the surface treatment is required first. The adhesion of plastics to various materials is a key problem to be solved in surface treatment. Generally speaking, the bonding properties of plastics are related to the structure and composition of materials. Some plastics are nonpolar and do not stick well, including polypropylene (PP), polytetrafluoroethylene (PTFE), PEEK and POM. PP, PE and other polyolefin materials, the surface energy is very low, usually only 30 Dyne. To achieve good adhesion, the surface energy is generally required to be no less than 36 Dyne. The bonding strength of PE can be increased several times after plasma treatment. After the same treatment, the bonding strength of PP will be significantly improved after the ionizing treatment. Plasma provides an effective surface activation pretreatment for printing, painting or bonding. This is a reliable and effective way to improve the printing adhesion and bonding strength. Plasma processing is carried out in a vacuum device or space. Air is pumped out, low-pressure gases are pumped in, and energy is applied in the form of electricity. Plasma coating is one of the application fields of plasma technology. It is suitable for a wide range of applications and offers great potential for improving the function and value of materials. In a plasma coating, the entire surface of an object placed in the plasma is coated with a nano-thick polymer. This coating process takes only a few minutes. The coating is usually only a few dozen to a few hundred nanometers thick and is colorless, odorless and has no effect on the material's appearance or feel. At the same time, it's a permanent coating of material that binds at the molecular level The effects of plasma-activated surfaces can be clearly seen in subsequent production steps, including the measurement of surface contact angles: droplets form on untreated surfaces and plasma-activated surface water spreads (low contact angles).
