摘要:
A multilayer film (116) for covering interior wall (200) surfaces of an enclosure (401) includes a base layer (206) having a layer of wall adhesive (118) configured to provide an adhesive relationship between the base layer (206) and the wall surface (402). A stack of removable layers (206) is adhered to the base layer (206). Each removable layer (206) includes a layer of removable adhesive (204) disposed on an inner facing surface of each layer (206). Adjacent removable layers (206) are adhered to one another by a corresponding layer of the removable adhesive (204) that extends over at least a portion of each removable layer (206) such that a flap (202) that is free of the removable adhesive (204) remains along at least two opposite peripheral edges of each removable layer (206). The outermost layer (206) of the stack may be selectively peeled from the rest to expose a subsequent, clean layer (206).

摘要:
An automatic and pneumatically driven cleaning apparatus (100) and method for cleaning interior surfaces of a powder spray booth (10). The cleaning apparatus (100) includes a frame (102) that can be transported into the booth by an overhead conveyor (122). The frame has a number of air jets (114) that blow off powder from the interior surfaces. Propulsion air jets are also provided with the frame to pneumatically cause the frame to rotate. A lower stabilizer hub (151) may be used to stabilize the rotation of the frame. The frame is made of lightweight materials such as composite materials.
摘要:
A device is disclosed for transporting finely distributed media produced during the surface treatment of articles along at least one wall. Gas outlets (3) are distributed throughout the wall (1). The gas that comes out of these outlets (3) forms a gas cushion which keeps the medium away from the wall (1).
摘要:
Described is a cabin for the spray-coating of workpieces with powder material, the cabin having an internal space which is enclosed by walls (11), a floor (14) and a roof and which has a longitudinal axis along which the workpieces are moved, the cabin having a cleaning device (410) which can also be moved along the longitudinal axis. In order to make it possible to avoid to the greatest extent the need for a human operator to intervene, the cleaning device includes a rigid carrier (410) fitted with mechanical cleaning elements (42), such as scrapers or brushes, which press flexibly against the internal surface of the cabin as the carrier is moved. The cleaning elements (42) are located in a gap (43) between the end of the carrier and the cabin wall, closing off the gap by forming a flexible seal.
摘要:
Eine Vorrichtung zum Leiten von mit Overspray beladener Prozessluft einer Beschichtungsanlage, insbesondere einer Lackieranlage, hat einen Strömungsraum (34), welcher, zumindest bereichsweise von Wandelementen (38, 40) begrenzt ist und eine Lufteingangsöffnung (36) hat. Wenigstens ein Wandelement (38, 40) des Strömungsraumes (34) ist schwenkbar gelagert und zwischen einer Normalstellung, in welcher es den Strömungsraum (34) begrenzt, und einer Sonderstellung verschwenkbar. Außerdem ist eine Anlage zum Beschichten, insbesondere zum Lackieren, von Gegenständen (4), insbesondere von Fahrzeugkarosserien, angegeben, die eine Beschichtungskabine (6) umfasst, in welcher die Gegenstände (4) mit Beschichtungsmaterial beaufschlagbar sind und durch welche ein Luftstrom geleitet werden kann, der entstehendes Overspray aufnimmt und als Prozessluft abführt und nach unten durch einen für den mit Overspray beladenen Luftstrom durchlässigen Kabinenboden (18) aus der Beschichtungskabine (6) ausströmt. Mittels einer solchen Luftleitvorrichtung (32), die in einem Strömungsbereich (30) unterhalb des Kabinenbodens (18) der Beschichtungskabine (6) angeordnet ist, wird die mit Overspray beladene Prozessluft weitergeleitet. Die Luftleitvorrichtung (32) ist derart angeordnet, dass deren Lufteingangsöffnung (36) in Richtung auf den Kabinenboden (18) der Beschichtungskabine (6) weist, wobei die Normalstellung eine Leitstellung und die Sonderstellung eine Reinigungstellung definiert.
摘要:
The sticker wallpaper with more than one sheet of sticker membrane, static and Low Tack provides the best paint quality without spots. It protects the oven. When the surface sheet is considered dirty, it can be detached from the numbered strip revealing the next clean one. It is used for temporary deposition of the masking paper, isolates the oven with heat and improves the lighting.
摘要:
A powder spray booth includes a booth canopy wall arrangement to contain powder during a spraying operation; and a booth floor that is rotatable relative to the booth wall during a spraying operation. The floor can be rotated about an axis that is also the longitudinal axis of the spray booth. The booth may be generally cylindrical in shape with a round floor. The booth canopy and the top are supported on a base frame separately from the floor. By this arrangement, the floor can be rotated relative to the booth canopy. A powder extraction apparatus in the form of a low pressure duct suspended off the floor draws up powder that has collected on the floor. The extraction duct is stationary with respect to the rotating floor during a spraying operation. The floor may also be translated along the axis of rotation between a first position in which the floor can rotate and a second position in which the floor is sealed against a lower edge of the booth canopy wall. The booth canopy and floor are made of composite materials that are very low in conductivity to minimize powder adhering to the floor and booth walls. The booth is thus easy to clean with a substantially shorter time period required for colour change.
摘要:
A powder coating system is provided comprising a powder spray booth (2) with a powder recovery system having an overspray intake (18) communicating with the interior of the booth. A diverter plate (26) may be held within the booth (2) to define with the booth floor (10), a duct leading to an overspray intake (18) of the powder recovery system. The diverter plate may include apertures for allowing oversprayed powder to be collected through the plate. The diverter plate may be provided as two or more diverter plates held at different elevation levels within the booth to define a duct which is larger in parts of the duct which are closer to the overspray intake than parts of the duct which are farther from the overspray intake. Alternatively or additionally, the coating system may include an air assist which provides jets of air across a portion of the interior surface of the booth. The surface may be one or more sloped portions (22) of the floor. The air supply may be pulsed to produce periodic bursts of air across the interior surface.
摘要:
The invention concerns a powder coating booth (1) comprising at least one spraying unit (4) connected to at least one powder-preparation and feed unit (6). This booth has a small base surface and is in the form of a column whose height depends on the workpiece to be coated. A closable slot (3) is provided in at least one of the booth walls and is designed for the passage of at least one powder-spraying unit (4) . In cross-section, the booth can be circular or square or combined, for example oval, rectangular or the like. When the slot(s) (3) is (are) closed, a cleaning unit (20) is introduced and automatically cleans the booth interior. In addition, at least one double flap arrangement (32) can be provided on a booth wall area such that the booth can be switched universally to automatic and/or manual operation. If a lock device is provided on the inlet and/or outlet side, it can be transformed to form a pre-coating space or after-coating space. Furthermore, preferably at least the booth wall area opposite the powder-spraying unit (4) is non-conductive. To this end, this wall area can be made totally or partially from a non-conductive material. If necessary, a non-conductive coating can be applied to the corresponding necessary areas or to entire wall surfaces.
