Decorating facing material and method of its production

FIELD: process engineering.

SUBSTANCE: invention relates to decorative facing material. Proposed material is produced on the basis of quenched cullet. First, mould welts of charge made on the basis of liquid glass or sand, or fire clay granules, or foamed concrete are applied on conveyor belt. Between said welts ledges are formed from filling agent. Space between said ledges is filled with quenched cullet. Then, decorative layer of quenched cullet is applied and annealed. Backside of obtained material is cellular. Cellular part makes about 80% of material volume. Said cellular part may be either hollow or filled with sand, concrete, foamed concrete or fire clay. To obtain material with hollow cells, said ledges are coated by kaolin clay suspension that allows separation of quenched cullet from filling agent.

Schematic diagram of the linear production of a new reinforced decorative finishing material "PKK mesh with hollow mesh part is shown in figure 1.

Production line operating in the continuous mode, includes transport system from paper or glass cloth tape (1) infeed, mesh or slat conveyor-conveyor (2) and roller conveyor (22). The charge for skirting the form of a bunker-mixer (3) fills the voids forming the shaft of the node forming boards (4), and 2 parallel sides (5)limiting the width of the material is applied to the transport of paper or glass cloth tape, and the mixture of the filler from the hopper of the mixer (6) fills the cells forming the shaft of the node (7) and in the form of projections-something (8) makes the carpet, from the tabs-something between sides of forms, on the same tape transport. Node (9) carry out the drying ledges-something and sides of the form, limiting the width of the material node spray (10) causes kaolin suspension on the inner side of the side forms and the rug is C projections-something, providing the Department of sintered stekloprokata from the filler, and the node (11) carries out the drying of kaolin suspensions. Node (12) fills stekloprokata the space between the ledges-miles from anywhere, in addition to the space at the edges, and node (13) this filling is compacted. Next node (14) is installed reinforcing mesh, and node (15) is applied to the face layer of colorless or colored stekloprokata simultaneously filling the space between the ledges-something and bumpers. Next node (16) causes on the face of the decor layer by spraying or drawing by screen method. Next, the resulting carpet comes in electric or gas kiln (17)operating temperature sintering of the base glass with a neutral atmosphere. On exit from the furnace of burning the carpet to prevent plastic deformation and temperature required for a given oxide decorative coatings, partially cooled by the host (18), on the carpet node (19) is applied decorative oxide coating and then the carpet is fed into the furnace annealing (20). At the exit from the annealing furnace sintered material arrives on site cutting (21), where it is cut into specified formats (plate), ready plates (23) are cleaned and, if necessary, act on the part of the molding and coating fasteners reinforced and further packaging.
