Abstract

The utility model relates to building materials, in particular to decorative materials used for decorating walls, building facades and other surfaces. The purpose of the proposed utility model is to increase reliability by reducing fragility. The utility model is implemented as follows: the base is covered with a layer of metal. The coating is carried out by a high-speed gas-thermal coating spraying device. The principle of operation of the device is based on the fact that filler material is introduced into the high-energy jet into the high-energy jet formed by burning in the combustion chamber under certain conditions, which then forms the coating.

Description

Technical field

The utility model relates to building materials, in particular to decorative materials used for decorating walls, building facades and other surfaces.

State of the art

Glazed ceramic tile is known (see).

The composition of the known device includes a base layer of glaze. A feature of the known tile is the lack of reliability in its use.

The disadvantage of this device is the relatively large fragility.

The purpose of the proposed utility model is to increase reliability by reducing fragility.

This goal is achieved due to the fact that in the finishing tile containing the base with the first and second surfaces located on opposite sides of the base, and an additional layer placed on the second surface, the additional layer is made of a metal layer formed by bombarding the base with molten metal particles, obtained during the melting of metal particles during the combustion of a combustible mixture and their joint flow at high speed.

Brief Description of the Drawings

A utility model is illustrated by a drawing, which shows a tile with a metal layer applied to it.

Utility Model Disclosure

The figure shows: the first surface 1, the soil layer 2, a metal layer formed by bombarding the base with molten metal particles obtained during the melting of metal particles during the combustion of a combustible mixture and their joint flow at high speed, 3 (hereinafter referred to as the metal layer), the second surface 4, base 5.

The main element of the device is base 5. Base 5 can be made of any shape, in the particular case made in the form of a rectangular tile. The base has a first surface and a second surface. The first surface and the second surface are parallel to one another.

A soil layer may be applied to the second surface. A metal layer is applied to the soil layer. The metal layer is formed by bombarding the base with particles of molten metal. The metal is melted due to the combustion process of the combustible mixture. The bombardment was carried out by dispersing particles of molten metal to a speed of more than 200 m / s with a gas stream of hot products of combustion of a combustible mixture. The peculiarity of obtaining a metal layer in this way is that the metal is sprayed in the environment of the combustion products without oxygen. The metal used for application to the second surface may be different, for example, may be

used iron, copper, zinc, tin, bronze, silver, gold, platinum, aluminum and other metals. The soil layer and the metal layer are depicted conditionally. The soil layer and the metal layer are made significantly less thickness relative to the thickness of the plate. The soil layer is applied in a particular case, in other cases, the soil layer may not be applied (in this case, the metal layer is applied directly to the substrate).

Utility Model Implementation

Finishing tile is obtained as follows. The base is obtained by cutting, molding and other possible ways. The second surface of the base is located opposite the device for applying metal. The base is covered with a layer of metal. To achieve this goal, they use a device called a high-speed gas-thermal coating spraying device. The operation of the device is based on increasing the dynamic parameters of a two-phase flow and ensuring the flight speed of particles of the sprayed material more than 200 m / s. The principle of metal deposition is based on the fact that metal, which then forms a coating, is fed into the stream formed by burning various hydrocarbon fuels under certain conditions and having a speed of up to 1500 m / s. In the process, as the parts and elements of the high-speed spraying device are heated, the burning rate of the working mixture increases. The resulting high-speed stream of hot combustion products of the combustible mixture picks up metal particles. A high-speed stream warms up and melts the particles, compresses them into a beam of small diameter and is able to accelerate preheated metal particles to speeds of the order of 240 ... 300 m / s. Metal particles acquire a significant normal component of velocity. Due to inertness, the metal particles continue a rectilinear motion, in contrast to the products of combustion of a combustible mixture. Particles

metal interact with the second surface, penetrating into all the pores of the second surface, thereby increasing the adhesion of particles to the second surface. The adhesion to the surface is 42 ... 48 MPa, and the porosity of the coatings ranges from 1.5 ... 5.0%.

Thus, when applying a layer of metal on the base, its strength and durability increase when exposed to external environmental factors. The metal layer does not peel off over a long service life.
