Description

 The invention relates to the building materials industry and is intended, in particular, for the manufacture of products based on silicon binders.

 A known method of manufacturing products from a material based on silicon binders [1], including the preparation of components, the preparation of mixtures of alkaline-silica modifications of silicon dioxide in grains, ordinary and ground quartz sand, crushed stone, alkali solution and some other additives, molding products from a mixture and their heat treatment. Known closest to the claimed solution is a method of manufacturing products from materials based on silicon binders, in which the mixture is additionally subjected to vibration processing on known equipment used in the manufacture of reinforced concrete products [2]. The disadvantages of this method are the low strength of the products associated with the insufficient degree of compaction and homogenization of the mixture, achieved due to its vibration directly in the molding device, and the inability to ensure due to vibration processing a sufficient degree of removal of air and excess liquid phase from the mixture, due to that mixtures based on silicon binders have high rigidity even with a high content of the liquid phase; high energy costs for the manufacture of products associated with the firing and grinding of quartzite and long exposure to heat treatment.

 The objectives of the invention are to increase the strength of products by increasing the density and homogenization of the mixture during molding and reducing energy consumption by intensifying crystallization, reducing the proportion of costly components and eliminating massive shaping from the process.

 The problem is solved due to the fact that when using characteristics characterizing a known method of manufacturing a product based on silicon binders, which includes preparing the components, preparing a mixture of alkaline-silicon binder and quartz filler as the main components, molding the product from the mixture and its heat treatment, in accordance with the invention, the prepared raw material is subjected to activation and homogenization directly in the form of the creation of forces providing shear def the formation of components by densifying the mixture by multidirectional forces with the displacement of the solid components relative to each other. The shear deformation of the mixture by compaction by multidirectional forces with the displacement of the solid components relative to each other provides continuous removal, dispersion and movement into the liquid phase of gel-like formations formed on the surface of silicate grains in the zones of their contact with simultaneous mixing and homogenization of the mixture, significant intensification of crystallization and a high degree of compaction the mixture as a whole. The proposed embodiment of the method of manufacturing products based on silicon binders is simple, does not require high energy consumption, provides high quality homogenization and compaction of the mixture.

 In more detail, the inventive method is considered in the following example of its implementation, schematically shown in the drawing.

 A product is formed from a material based on a silicon binder in the form (1) shown in the diagram and formed by a pallet (2), fixed (3) and movable (4) sides, power cylinders (5) and a pressure plate (6), which is placed in the inner cavity of the form and pivotally fixed in the middle section on the cylinder rod with the possibility of vertical movement and change of the angle of inclination relative to the horizontal plane. In this case, the movable walls are equipped with clamps, eliminating the gap between them and the pressure plate. For the manufacture of the product in a known manner, a mixture of an alkali-silicon binder and quartz filler is prepared, which is loaded into the described molding device in which it is subjected to activation and homogenization. In this case, using the power cylinders (5), the mixture is compacted by vertically lowering the pressure plate (6) with a simultaneous alternating change in its angle of inclination relative to the horizontal plane, which simultaneously ensures the activation of the surface of the particles due to shear deformations of the components of the mixture, its homogenization and compaction with extrusion air and part of the liquid phase out. Due to the clamps, the gap between the movable walls and the edges of the pressure plate is reduced to sizes that allow the extruded air and water to leak out, but retain the solid components of the mixture.

 Testing of products obtained in this way showed an increase in strength compared with products obtained by known methods, by 25-30% with a significant reduction in energy consumption.

 The inventive method of manufacturing an article from a material based on silicon binders completely solves the problem facing the invention.

 The claimed technical solution with the technical features characterizing it is currently unknown in the Russian Federation and abroad and meets the requirements of the category of "Novelty".

 The inventive method is original, does not follow obviously from the existing level of technology and meets the requirements of the criterion of "Inventive step".

 The inventive method can be implemented industrially using well-known technical means, raw materials and materials and meets the requirements of the criterion of "Industrial application".
