With Clean Cloth, Clean Paper Can Make The Copolymer Get Good Anti-static Performance
In the copolymerization, especially in the graft copolymerization, the first ray of radiation monomer mixture, often make the copolymer to obtain good antistatic properties. For example, acrylic or methacrylic acid previously irradiated with p-rays grafted onto polyethylene and polypropylene reduces the ability of the polymer to accumulate static charge. Pre-treated with polyethylene and then ozonated acrylic acid, but also to achieve the same effect. Another example is the first radiation with a ray, and then grafted methacrylic acid polyamide, its antistatic properties significantly improved, while heating at the same time. c. Source ^ y ray irradiation, with a high copolymerization ability of acrylic acid, acrylamide, 2-vinyl pyridine, vinyl-3-ethyl silane and a mixture of grafted onto PTFE, made of Films have the ability to reduce triboelectric charging. Even with static charges accumulating, static charges leak out as corona discharge at room temperature and 9.65%.
Light irradiation can also be used to surface modification of polymer dust-free paper materials. For example, in the UV irradiation, some hydrophobic synthetic cloth fibers or film surface can be polarized to form a hydrophilic surface, thereby enhancing the material's antistatic properties. It can be considered that the surface of hydrophobic polymer material treated with UV rays will generate polar groups such as hydroxyl group and carboxyl group which can form hydrogen bonds with water molecules on the surface to improve the conductivity of the surface of the clean cloth material.
Ultrasonic surface treatment either through the sound source and the treated dust-free paper material in direct contact with the way, but also through some of the liquid medium to achieve. In the liquid medium, the cavitation effect, the impact effect, the pulse resonance bubble and the variable sound pressure generated by the ultrasonic wave act on the polymer dust-free paper material, and the material to be treated will produce a series of physical and chemical changes. For example, the polystyrene or polyolefin products soaked in petroleum ether, followed by ultrasonic treatment can be achieved to prevent static electricity from acting. After this treatment of the product at 25 ~ C and jealous = 80% of p. Can be reduced to 10 '. n. Hydrophobicity of some of the hydrophobic synthetic fibers sonicated has been significantly improved.
