Application of plasma surface cleaner low temperature plasma technology in plastic surface modification:
Plastic materials have the advantages of abundant raw materials, easy processing and manufacturing, light weight, low price, appropriate mechanical properties, good waterproof and moisture-proof properties, and easy compounding with other materials. However, the surface tension of the plastic film is relatively low and cannot fully meet the requirements of the printing process. The use of plasma surface cleaner plasma equipment to modify the plastic surface can improve the performance of the plastic and broaden its scope of use.
The advantages of plasma surface cleaning machine: simple operation, large monomer selection range; giving various excellent properties to the modified surface; the thickness of the surface modification layer is extremely thin (from a few nanometers to hundreds of nanometers), only changing the surface properties of the material, The overall nature of the substrate remains unchanged; an ultra-thin, uniform, continuous and non-porous high-function film can be produced, and the film has a strong adhesion on the substrate, which is convenient for forming a film on the surface of various carriers.
The unique surface modification effect of the plasma technology of the plasma surface cleaner provides a new way for the modification of polymer materials. Low-temperature plasma processing is an environmentally friendly technology. It is a gas-phase dry chemical reaction that allows substances to absorb electric energy without adding chemical reagents, leaving no residue on the environment, and avoiding the treatment of a large amount of waste liquid; it saves water Energy saving, pollution-free, effective use of resources, and the benefits of environmental protection.
Treating materials such as PE, PP, PVF2, LDPE, etc. with low-temperature plasma under suitable process conditions, the surface morphology of the materials has changed significantly, and a variety of oxygen-containing groups have been introduced, which makes the surface change from non-polar and difficult-to-adhesive to organic Certain polarity, easy adhesion and hydrophilicity are good for bonding, coating and printing.

Most organic gases are polymerized and deposited on the solid surface under the action of the low temperature plasma of the plasma surface cleaner to form a continuous, uniform, and pinhole-free ultra-thin film, which can be used as a protective layer, an insulating layer, a gas and liquid separation film, and a laser Light guide films, etc., are used in many fields such as optics, electronics, and medicine.
Both polymethyl methacrylate or polycarbonate plastics can be used to make inexpensive and easy-to-process optical lenses, but their surface hardness is too low and scratches are likely to occur. Using organic fluorine or organic silicon monomers, using low-temperature plasma polymerization technology to deposit a thin layer of 10nm on the surface of the lens can improve its scratch resistance and reflection index.
Using low-temperature nitrogen plasma to initiate graft modification of polyester fabric with acrylamide, the dyeing percentage, dyeing depth and hydrophilicity of the polyester fabric after grafting are significantly improved.
Plasma surface cleaners are in a period of vigorous development. The use of low-temperature plasma technology to modify the surface of polymer materials has shown its broad application prospects.
The continuous maturation of low-temperature plasma plastic film modification technology and the promotion of industrialization of plasma surface cleaners will bring us higher-quality food and beverage plastic packaging; from the standpoint of sustainable development and environmental protection, as an achievable The low-temperature plasma technology of high-functionality and high-value-added processing will be paid more and more attention.
