    摘要: A two part waveguide consists of a fixed part formed of a metal sleeve provided with metal dividing walls and a movable part formed by a helix positioned within the sleeve and rotatable sleeve about an axis coaxial with the axis of the cylindrical sleeve. A plurality of magnetrons are positioned on the outer surface of the sleeve. The sleeve includes two openings, one for admitting material to be treated and the other for discharging the material to be treated. The openings are dimensioned so that the microwaves cannot leave the waveguide.

    摘要: The present invention provides an apparatus for the manufacture of pre-expanded particles, which comprises in combination a heat-insulated resonating cavity, with a high-frequency electromagnetic source of energy, a ferrite circulater, a wave guide, an Archimedes screw for the introduction of the plastics material to be pre-expanded, a pump for regulating the feed of polar liquid and a device for extracting the pre-expanded particles. The present invention provides also a process for the pre-expansion of particles of plastic material using said apparatus.
