Explosive-coating system

摘要

The system contains a mixing device (4) which is connected via valves (9, 10 and 11) to the sources (5, 6 and 7) of gaseous components of the explosive mixture, and of a neutral gas, respectively, and is connected, via a non-return valve (49) and a safety device (3), with an explosion chamber (1). This is of tubular shape and connected to a dosing device (2). The latter is used for the addition of predetermined amounts of pulverulent coating material and is connected laterally to the closed tube end of the explosion chamber. The mixing device (4) contains two chambers, the first chamber (27) being connected to the source (5) of one of the components of the explosive mixture and to the source (7) of the neutral gas. The second chamber (38) is connected to the first chamber (27) and to the source (6) of the other component of the explosive mixture. The main application fields of the invention are as follows: coating of workpieces in aircraft construction, shipbuilding, rocket construction and mechanical engineering, gas turbine technology, textile and paper industry, construction of measuring instruments and chemical equipment etc., which are subject to heavy corrosion, erosion and thermal effects. <IMAGE>
