(54) DEVICE FOR FINISHING CONSTRUCTION PRODUCTS

one

The invention relates to the decoration of building products.

The device is a device that allows to obtain a color decorative finish for building products, which is a plasmatron mounted on a movable base and a bunker feeder, which is connected by a pipeline with the shut-off and control equipment (1.

A disadvantage of the known device is the impossibility of obtaining high-quality polychromatic image by applying primary colors, since subsequent colors can be applied after applying the previous ones, which have cooled down completely by that time, and when applying the next layer, the entire coating cracks, which reduces both the decorative and construction quality of the product. .

The purpose of the invention is to increase the quality of the polychrome coating.

This goal is achieved by the fact that a device for finishing building products, including a plasmatron mounted on a movable base and a feeder bin.

communicating by pipeline with locking equipment, has, on the basis of, an additionally installed in series at least one plasmatron, also equipped with a bunker-feeder, each bunker being divided into at least two isolated sections that communicate with the plasmatrons.

The drawing shows a device for finishing building products.

The device consists of a movable base I, moving along guide 2 on rollers 3. Plasma torches 4 are attached to base 1. Each plasma torch is connected to its own feeder 6 by means of pipe 5, each of which has three sections — 7–9. Section 7 is filled with red powder, section 8 is filled with a blue powder, section 9 is filled with a yellow color powder. Each feed hopper has a locking control device 10 connected by cable 11 to a control panel 12 equipped with a computer. The computer has a program for color surface finishing on various tinted surface areas 13.

The layers of 14-16 primary colors obtained from plasma torches 4 form a film.

The device works as follows.

Covered surface 13 is divided into color sections in accordance with the artistic intent. Then the device is turned on, and from the computer of the control panel 12 via cable 11, the command is sent to the shut-off equipment 10. Powder from any section 7, 8 or 9 of the feed hopper 6 enters through the pipeline 5 to the plasma torch 4, where it enters the stream of low-temperature the plasma is heated to melt and is carried by the plasma-forming gas to the surface 13 to be coated, forming transparent layers 14, 15 or 16 of film on it, depending on the location of the plasma torch.

After applying a film from any section of the first computer metering hopper, a second plasma torch and a metering hopper connected to it are included, in which one of the sections is turned on, and a second film of a different basic color is applied to the first film of one of the primary colors, then a third plasma torch and metering hopper, and a third film of the third primary color is superimposed on the two films obtained. Films of primary colors when overlapping each other in various combinations give a multi-color coating with an unlimited range of colors, similar to a ceramic lining. In this case, the inclusion of various chambers in dispensers is carried out according to a previously developed program as the device moves over the surface to be coated. Above each tinted area of the three dispensers, the sections are switched with the powders to obtain in this area when applying coating films of the desired color. The compositions of sprayed powders of the three primary colors may be different.

The proposed device for the decorative finishing of building products can be applied to the finishing and early construction of buildings, since the proposed technology does not require the formation of a facing layer on the surface, unlike the known methods. The proposed device can also be applied in house-building factories in production lines for the production of wall panels, as well as for decorative painting, replacing mosaic. In connection with the transition to panel housing, the proposed device can replace the painting of building products, plastering, lining them with a special tile or decorative decorating the surface with a mosaic panel. Multicolor paintings made with this device have a shiny or matte glazed surface and are highly weather resistant and have sufficient adhesion to the surface layer of the part. The proposed device makes it possible to obtain various ornaments, drawings, artistic compositions both monochrome and multi-color on the surface of building parts made of concrete, brick, stone, gables, thus completing the color scheme of buildings or already constructed buildings.
