  • Patent number: 9192955
    Abstract: Device for carrying out surface treatment on large objects, such as spray-painting of ships. In the prior art, a substantial proportion of the spray mist is deposited elsewhere, which is unwanted. The device proposes an enclosure which is movable along the hull of the ship, from which the spray-painting operation can be carried out through an opening disposed in the enclosure. An air curtain extending to the hull of the ship is present around this opening, through which it is not possible for spray to escape between the enclosure and the ship's hull. An extraction facility for mist is present in the enclosure and supply openings for air are provided. The enclosure consists of a housing which is accessible via a door.

The media size changer is operably located in the diverging passageway and has one or more media size changing members to fragment moving blast media particles by impact therewith. The blast media particles are provided to the media blast nozzle in an initial consistent size, and when a moving blast media particle impacts with one or more media size changing members, two or more fragments of reduced size are created from the initial blast media particle for ejection from the nozzle device. The media size changer can be adjusted by an operator to eject whole particles or fragments of particles.

  • Publication number: 20120115400
    Abstract: The method of the present invention includes: a first blasting step of carrying out blasting of the surface of a metal base material, such as a shower head or a processing container, by using a blasting material composed of a non-sublimable material (e.g. alumina); and a second blasting step of carrying out blasting of the surface of the metal base material, which has undergone the first blasting step, by using a blasting material composed of a sublimable material (e.g. dry ice). The first blasting step properly roughens the surface of the metal base material so that a film, which adheres to the surface during film-forming processing, hardly peels off. In addition, the second blasting step almost fully removes the residual non-sublimable blasting material adhering to the surface of the metal base material, thereby preventing the generation of particles deriving from the residual non-sublimable blasting material falling off the metal base material.

    Abstract: A glass manufacturing device includes a work container, a loading device, a sandblaster, a shield device, and a lift device. The loading device is received in the work container and loads a glass substrate in place. The sandblaster is arranged opposite to the loading device and sandblasts the glass substrate. The lift device is connected to the shield device and used for pressing the shield device onto the glass substrate during the process of sandblasting. The shield device includes a shield cover having a number of shield units. The surfaces of the shield units facing the bottom of the work container are engaged with elastic washers. The shield units are configured to shield portions of the glass substrate and prevent the portions of the glass substrate from being cut during sandblasting.

  • Patent number: 8066549
    Abstract: A method is provided for removing iron oxide scale from sheet metal and producing a sheet metal surface with rust inhibitive properties. The sheet metal is advanced through the descaling cell and a slurry mixture is propelled against at least one of the top surface and bottom surface of the sheet metal across the sheet metal width as the material is advanced through the descaling cell. The rate of slurry impact against the at least one of the top surface and bottom surface of the sheet metal is controlled in a manner to remove substantially all of the scale from a surface of the sheet metal, and in a manner to create a passivation layer on the descaled surface of the sheet metal. The passivation layer comprises at least one of silicon, aluminum, manganese and chromium and inhibits oxidation of the descaled surface of the processed sheet metal.
