Description

one

The invention relates to the building materials industry, in particular to the glass industry, and can be used in glass factories producing glass blocks, double-glazed windows or other translucent structures that serve to protect against various types of radiation.

A device is known that comprises a pair of transparent plates of electrically insulating material placed at a distance and connected along the perimeter to form a closed air chamber. On the inner surface of the plates are placed electrical heating resistive elements / connected with collecting tires into a single heating circuit 1

The known glass block structure, according to which the glass block has holes, through which the internal cavity can be evacuated, filled with spadial gases, covered with a metal film, i.e. in the case of metallic coating. films these glass blocks can to some extent serve as a protection against microwave radiation 2.

However, the radiation protection factor for such glass blocks is very

i is low, since in this case the requirement to create a continuous electrical contact over the entire area of the glazing assembled by individual elements (blocks) is not satisfied. At the boundaries of the blocks along their perimeter, through the thickness of the glass, microwave radiation breakthroughs are observed. The closest ones are technical.

0 essence to the invention. is a block containing two semi-blocks, hermetically joined together with the formation of an internal cavity filled with liquid h.

The purpose of the invention is to provide protection against microwave radiation.

This goal is achieved by the fact that a glass block containing two half blocks, hermetically connected

0 with each other with the formation of an internal cavity filled with liquid, provided with a metal frame placed between the semi-blocks and brought out to the outside along the entire perimeter of the block.

The semi-block is interconnected by means of an epoxy compound, and between the semi-blocks there is a frame made of a thin sheet of soft metal-alloy (for example, aluminum).

0 The external dimensions of the frame are 3-5 mm larger than the dimensions of the joint structural elements, which ensures a single contact of the individual elements of the glazing units when they are mounted in the light opening. The internal cavity of the blocks is filled; electrolyte solution. To fill the electrolyte in the inner cavity, one of the structural elements of the semi-block is made of a diameter of 4-5 mm, which is filled with a cork, which is a metal rivet mounted on the epoxy compound, after the cavity is filled with liquid. To prevent the unit from collapsing when the temperature and barometric pressure fluctuate inside its hydrostatic pressure. During operation, the electrolyte is poured so that an air volume of about 20-30 mm in height remains in the upper part of the unit. At the same time, in order to avoid violation of the splice of another contact of the electro. Lita with aluminum lining, the latter is made in the upper part of the wide wide. This part of the frame serves as a screen recessed into the electrolyte and providing a continuous electrical contact. To reduce the electrolytic corrosion of the aluminum frame, an inhibitor (0.01% K C rj O 7) was introduced into the electrolyte (for example, 20% NaCt solvent). The glass block can be made of a semi-block and glass. In this case, the power can be used as usual window, and with special properties. The advantage of the proposed design is that it satisfies the requirement for glass blocks used to protect Tbi from various types of radiation (for example, microwave) - continuous electrical contact over the entire area of the ridge. FIG. 1 shows a block of two half blocks; in fig. 2 - a block of semi block and sheet glass. The glass block consists of two half blocks 1 or a half block and glass 2. The contact planes of the 3 half blocks can be ground to improve adhesion to the epoxy package and to achieve the required flatness between the connected pieces. The combination of the elements of the semi-blocks 1 and the semi-block and the glass 2 is realized with the help of the epoxy compound 4 through a frame made of a soft metal (for example, thin sheet aluminum). Frame 5 in the upper part has a screen 6 embedded in the electrolyte 7 The electrolyte is so filled) that in the upper uacTijt there is a glass block. you have an air volume of 8. The hp filling of the Yai electrolyte of the internal cavity 9 of the heckblock has an opening 10 that is closed by a stopper 11 on the epoxy compound 12. To fabricate prototypes of the glass block of the proposed design, equipment is used for the production line of welded glass blocks - half blocks. Two semi-blocks 1 of 240x240 mm in size with machined (ground) surfaces 3 on the washer, in one of which a hole 10 is drilled, are mounted on a horizontal plane in close proximity to each other. friend On ground surfaces 3, a bundle of epoxy compound 4 is applied using a special syringe. Then, a frame 5 of 0.3 mm thick aluminum sheet is installed on the surface 3 of a half block with a hole 10. The frame is manufactured with an external dimension of 250x250 mm and an inner window in a frame of 205x190 mm. The frame is placed in such a way that the screen b is on the side of the opening 10. Then, on the frame 5, a second half block 1 is superimposed on top of it, which is centered relative to the edges of the lower half block. The block thus assembled is placed in a drying oven for heat treatment. After heat treatment, the finished unit is filled with electrolyte and the filling hole 10 is sealed with a stopper 11 in epoxy, compound, de .. The economic effect of introducing the proposed invention is obtained by increasing the radiation protection efficiency in comparison with the protection by radioprotective glass with a two-sided coating, and by reducing the cost of glazing. The cost of one square meter. radioprotective glass is 130 rubles. With an estimated cost per square meter of radioprotective glass blocks 50 rubles. the economic effect is 80 rubles. per square meter of ± ± 1 square meter (the cost of one block measuring 244x244mm is 3 rubles at the wholesale price of a conventional glass block 47 kopecks). of the invention, the glass block that forms two semi-blocks, hermetically interconnected with the formation of an internal cavity filled with liquid, characterized in that, in order to provide protection from microwave radiation, the glass block is provided with a metal frame placed between the semi-blocks and brought out to the outside around the perimeter of the unit .
