Abstract

Usage: in the construction industry in the manufacture of bricks from the soil and other raw material mixtures. SUMMARY OF THE INVENTION: A method for making a brick from a soil includes filling the raw material mixture into a mold, pressing the mixture and pushing a brick out of the mold, and setting the bowl in the form of a hollow open prism from a thermoplastic material into the mold before filling the raw mixture. - the raw material mixture is closed with a plate of thermoplastic material, and before pressing the mixture, the shell and plate are heated to the melting temperature of the thermoplastic material. 5 il.

Description

The invention relates to the construction industry, in particular to methods for producing bricks from soil and other raw material mixtures.

A known method of making construction materials from the soil, including filling the soil into the mold, pressing in two stages at pressures of 1-2 and 6-8 MPa, applying to the surface of the block (brick) mineral in the living and hydrophobic liquid, respectively, after the first and second stages. The disadvantage of this method is the low strength and low quality of the bricks produced. In addition, this method complicates the technology of brick production due to the two stages of manufacturing and the presence of additional operations for applying the compositions.

The closest to the invention is a method of forming a brick, including the installation of facing plates in a mold, the filling of raw mix in

mold, pressing mixture, pushing out bricks.

The disadvantage of this method is the large energy consumption for the manufacture of bricks, since after molding it is necessary to perform operations on drying and firing bricks. Another disadvantage of this method is the high water absorption of the bricks obtained by this method.

The purpose of the invention is to reduce the energy consumption for the manufacture of bricks and reduce the water absorption of the resulting brick.

The goal is achieved by the method of making bricks, including filling the raw material mixture into the mold, pressing the mixture and pushing the brick out of the mold, lastly, before filling the raw mixture, the shell is made of a thermoplastic material cover plate of thermoplastic material, and before pressing the mixture shell and plate is heated to a temperature of "

melting tours of thermoplastic material.

FIG. 1-5 shows the sequence of operations characterizing the implementation of the method.

The method is carried out as follows.

In the mold 1 install the shell 2 in the form of a hollow open prism made of thermoplastic material. The raw material 3 is poured into the form with the shell and is covered from above with a plate 4, also made of thermoplastic material. The shell 2 and the plate 4 are heated before pressing to the melting temperature of the thermoplastic material from which the shell 2 and the covering plate 4 are made.

Then pressing is carried out by transferring the load through the press plate 5. After that, the finished brick is pushed out of the mold.

Example. The shell is made of sulfur in the form of a hollow open prism. Then the shell of sulfur is installed in the mold. The ground (clay) is poured into the shell to the level of its upper edge, and the shell with the ground is covered from above with a plate made also of sulfur.

The shell and plate are heated to 150-180 ° C. For this purpose, electric heaters embedded in the body of the mold are used. Then, brick is pressed and the finished

bricks from the mold. The shell and the plate can be made, in addition to sulfur, from other thermoplastic materials (low-temperature polyethylene, etc.).

The proposed method of manufacture significantly reduces the water absorption of bricks obtained by this method as compared to the prototype. Reducing the water absorption of bricks in turn helps to increase its frost resistance and durability.

In addition, the proposed method significantly reduces the energy consumption for the manufacture of chirpich, as it eliminates the operation

drying and firing bricks after molding. This also reduces the duration of brick production. The formula of the invention is a method of making a brick from the ground, including filling the raw material mixture into a mold, pressing the mixture and pushing the brick out of the mold, characterized in that, in order to reduce the energy consumption for making a brick and water absorption of the resulting brick, in the mold before filling the raw material set the shell in the form of a hollow open prism of thermoplastic material, which, after filling the raw material The mixtures are closed with a plate of thermoplastic material, and before pressing the mixture, the shell and plate are heated to the melting temperature of the thermoplastic material. 1 / / T // 7 J S / / S U / FIG. 2 Fig.Z FIG. five Fi.by 2 3
