Method and device for de-gassing a liquid-gas-mixture

InactiveCN102046255ALow viscosityImprove adhesionLiquid degasificationMicrosphereThin layer

A method and a device for de-gassing a liquid-gas-mixture is proposed. The method comprises: inserting the liquid-gas-mixture (3) into a chamber (5) wherein the chamber (5) is at a reduced gas pressure and arranging the liquid-gas- mixture (3) on a centre region (11) of a surface (13) of a rotating body (15) such that the liquid-gas-mixture (3) is subjected to a centrifugal force. Therein, the surface (13) of the rotating body (15) is adapted such that the liquid-gas-mixture (3) is spread over the surface (13) due to the centrifugal force and finally flows over a radially outward edge region (21) of the surface (13) of the rotating body (15). Due to the occurring centrifugal forces, even highly viscous or thixotropic liquids may bespread over the rotating surface as a thin layer from which gas incorporated in the liquid can easily and effectively escape. Thus, a rigid foam material having low specific weight and high electrically insulating properties can be produced from the de-gassed liquid comprising e.g. a resin into which microspheres are incorporated.

The invention discloses an electronic load restraining type high-voltage accelerating tube which comprises an electronic gun cathode emission surface, an electronic gun absorbing pole and a plurality of sections of accelerating tubes. Secondary electron beam limiting light bar devices are arranged among the accelerating tubes, and can effectively block secondary electron orbits.

Meanwhile the intensity of X-rays generated on the upper accelerating tubes by the secondary electrons can be reduced, and high-voltage stability can be increased. In addition, the secondary electron beam limiting light bar devices with a large caliber can reduce the influence to the vacuuming speed of an electronic gun area. Compared with other methods of restraining the secondary electrons, the electronic load restraining type high-voltage accelerating tube is simple in structure and convenient to install.
