The invention relates to the processing technology of building panels mainly from concrete and can be used in the production of large reinforced concrete steel panels and slabs.

The purpose of the invention is to improve the quality of finishing products by increasing their decorative properties.

This goal is achieved due to the fact that the production line for finishing construction products is mainly made of concrete, containing a drying oven installed along the technological process and a plasma manipulator containing a pigmenter installed in front of the drying oven, a buffer layer applying unit and a final drying oven placed between the sub-furnace and the furnace and the plasma manipulator. The pigmentator, which is part of the line, is equipped with at least two feeding devices that can be controlled and different color pigment mixtures costs.

Equipping the pigment machine with at least two feeding devices with the ability to control the costs of pigmenting mixtures of different colors allows you to enhance the positive effect achieved using the proposed line due to the possibility of expanding the range of color finishes.

The drawing schematically shows a production line for finishing building products mainly of concrete.

The finishing line for building products placed on the conveyor device 2 contains the pigment generator 3 installed in the course of the process, the drying oven 4, the buffer layer applying unit 5 (WEED), the final soot kiln and the plasma manipulator 7 o. The pigment 3 is equipped with at least two feeding devices 8 and 9 with the possibility of controlling the costs of pigment mixtures of 10 and 11 different colors.

Lini works as follows.

the current of the production line, equipped with pigment gator 3. Feeding devices 8 and 9 of the pigmenting device 3 supply and regulate the consumption of pigment mixtures 1 O and 11 different colors. For example, a mixture of liquid glass and chromium oxide after melting produces a green color, a mixture of liquid glass and cobalt blue oxide, and the like.

When the product 1 is moved by the transporting device 2 under the pigment 3 its surface is sprayed with a layer of pigment of a certain color. Next, The line is transferred to the next section, equipped with a drying oven 4, where moisture is removed and partial sintering of the mixture from a carrier, for example, water glass, and pigments takes place. Drying of the pigment layer prevents with further plasma treatment the blistering and peeling of: the decorative layer from the base material - concrete.

Then the product 1 is moved by the transport device 2 to the zone of action of the BNBS 5. The substance for the buffer layer is selected from among inert components that do not affect the color, for example, liquid glass. The coating applied by BNBS 5 protects the previously applied pigment layer from fading when subsequently exposed to plasma. Moisture removal and coupling of the buffer substance to the pigment layer are carried out in the area equipped with the furnace 6 of the final formulation. After heat treatment in this area, the wall panel of the transporting device 2 is moved to the area of high-temperature treatment by the plasma manipulator 7. Under the action of the high-temperature flame, the buffer layer partially or completely burns out. The residue of the buffer layer and the substance of the pigment layer are fused with the surface layer of the concrete product 1 and form a protective-decorative coating of a certain color.

The use of a pigmentator with several feeding devices greatly expands the color range of the decorative finish. Improving the quality of the decorative finish is also ensured by an increase in the adhesion strength of the substance of the decorative layer.

The proposed line allows to increase productivity due to the greater processing speed of products by about 3 times per I m, to reduce the cost of finishing 1 m more

than 2 times, and the power consumption for finishing 1 m in about 2 pa10
