Abstract

Binding, including beryllium oxide and water, characterized in that, in order to increase strength under normal hardening conditions, it additionally contains iodine oxide (y) in the following ratio of components, wt.%: Beryllium oxide 60-80 Iodide oxide I) 10 -30 WaterEverything Else

Description

00

The invention relates to the production of oxide-based oarylli and can be used in the nuclear industry, as well as in metallurgy and the construction industry.

Beryllium oxide based adhesives are known. The maximum strength in beryllium oxide bumps, sulfuric acid and water, forming a hardening structure under normal conditions, is 13.5 MPa Cl.

Closest to the proposed binder based on beryllium oxide, lactic acid and water, containing weight,%;

Beryllium Oxide 50.2 Lactic acid 39.8 Water10.0

The strength of such a treadmill reaches 24.0 MPa. To obtain it, a mixture of the above ingredients is prepared by rubbing beryllium oxide in an agate mortar and mixing. its 80% lactic acid solution. After that, the mixture is thoroughly mixed and, at a specific pressure of 45-, O MPa, samples of CYLINDER with an ISrlCTivi height are formed. The samples are cured under the usual conditions of condition 23.

A disadvantage of those known in Zhuvts1x is their relatively low compressive strength.

The purpose of the invention is to increase the firmness of a thirsty under normal hardening conditions.

This goal is achieved by the fact that, in a thirsty, including beryllium oxide and water, additionally contains iodine oxide at the following ratio of components, wt.% 1 Beryllium oxide or80

Iodine oxide 10-30

WaterEverything

The optimal composition of the substance corresponds to the content of the ingredients, beryllium oxide 70. Iodine oxide20

Water Remaining (up to 100%) Three mixtures of ingredients are made up to produce the proposed binder. The first mixture contains wt.%: Beryllium oxide 60, oxide y.odo 30, water 10, the second - beryllium oxide 70, oxide yrda 20, water 10 and one third - beryllium oxide 80, hydroxy. Iodine 10; water 10. The initial solid components of each mixture are carefully perched in an agate mortar and shut off with water, the mixture is mixed again, and samples of 1–1.0 in diameter and 1510 m in height are prepared at a specific pressing pressure of 45.0 Sh. Solid. specimens under normal conditions.

The results of testing samples for ultimate compressive strength are shown in the table.

As can be seen from the table, the strength of the Proposed Identity exceeds the strength of the known. The proposed binder can be widely used in the nuclear industry as protection against ionizing radiation, in the building materials industry, and in construction as self-sustaining or as an additive - the accelerator of concrete. The application of the invention will expand the range of beryllium oxide-based substances, combining high strength characteristics with special properties.
