  8. A novel plasma technique to coat anilox rolls

    Anilox rolls are the key elements of the aniline ink distribution system used in printing for processing of paper and textile materials.

Deposition of binary chemical compounds (such as nitrides, oxides, carbides) increases the strength and corrosion resistance of the anilox rolls and increases its moisture resistance. The special design of the vacuum chamber allows to move the anilox rolls from the heating zone to the plasma cleaning zone, and then to the application zone, where the rotation of the cylindrical magnetron forms a coating.

  18. DC glow-discharge plasma sterilizer for medical equipment

    The operation of the plasma sterilizer is based on the use of a glow discharge of direct current, which provides the creation of a dense and highly homogeneous plasma directly in the space in which the sterilized products are located. Plasma of this discharge is more effective for rapid sterilization of medical instruments, especially products with channels or long holes. The sterilization process involves the repetition of treatment cycles, consisting of two phases - "steam" and "plasma". During the first phase, the chemical vapor is injected into a pre-evacuated sterilizer chamber. The special system of injection and evaporation provides very effective penetration of steam into packages and difficult places of the processed products. After the "steam" phase, the chamber is evacuated again, and a glowing DC discharge is ignited. The medium used to generate plasma is a mixture of hydrogen peroxide and water vapors, as well as molecular oxygen created by the decomposition of hydrogen peroxide.
