The invention relates to methods of producing the raw material mixture for the manufacture of finishing and decorative building products.

Known methods for producing products, such as slabs of mixes based on magnesia cement, consisting of caustic magnesite, bischofite and sawdust, which are a source of saturated ambient air ions of magnesium and other elements and are recommended for use in aeroionotherapy. This effect is achieved through the use of a mixture of an aqueous solution of bischofite (MgCl2·6H2O), the Foundation of which is magnesium chloride. Bischofite was recommended by the Ministry of health of the USSR as a balneologic stuff means.

In areas with products from this mixture, a marked beneficial effect on the surrounding air due to the stabilization of temperature and humidity, and saturation of air ions of magnesium and other trace elements. However, a significant effect of saturation aerons bromine, magnesium and especially iodine to achieve for a long time is not possible. In addition, when using an aqueous solution of magnesium chloride obtained by chemical means, instead of natural bischofite, operational characteristics of the mixture are retained, but the air is not saturated with ions of magnesium, bromine and iodine.

It is known that iodine is a volatile substance. Therefore, when introducing it into the mix effect separation of ions of iodine is only valid for a short period of time. Because of this, substances or solutions containing iodine, in mortar was not used. The provision of an increased excretion of ions of magnesium and bromine for the desired gain balneological effect is possible due to the significant increase in the content of bischofite solution in the mixture. However, the increase in the content of bischofite solution leads to a degradation of the performance - cracking products from this mixture, therefore, is not practical (Technical encyclopedia, t. Edited Lkkaracan, editorial technical encyclopedias and dictionaries, M., 1939, str).

The closest known method is a method of obtaining the raw material mixture for the manufacture of finishing and decorative building products, comprising mixing caustic magnesite with sawdust, moistening the mass aqueous solution of magnesium chloride, the final mixing (Patent RF №2090535, 20.09.97, bull. No. 26).

However, this method cannot obtain the raw material mixture, which has a Spa effect with increased allocation ions of iodine, magnesium and bromine over a long period of time and maintaining key performance characteristics, for example durability, crack resistance.

The objective of the invention is to create methods of obtaining compositions of the raw material mixture for the manufacture of finishing and decorative building products with Spa effect with increased allocation ions of iodine, and/or magnesium and bromine over a long period of time, while maintaining the basic performance characteristics, such as durability, crack resistance.

The technical result from the use of the invention is to provide methods of obtaining compositions of the raw material mixture having as essential performance characteristics, and its health effect for a long period of time of operation of the products made from these mixtures.

The achievement of the task is carried out by the methods of obtaining the raw material mixture.

The method of obtaining the raw material mixture for the manufacture of finishing and decorative building products, in the first embodiment, includes mixing caustic magnesite with sawdust, moistening the mass aqueous solution of bischofite, the final mixing. A distinctive feature is that the mixture in an amount of 0.3 to 0.6 OBC the Iodinol pre-mixed with an aqueous solution of bischofite.

Introduction Iodinol the in composition of the raw mix as an independent component, does not increase the duration of excretion of ions of iodine. The iodine in the solution of polyvinyl alcohol, easily evaporates. Inhibitory effect separation of ions of iodine observed only when pre-dissolving the Iodinol in aqueous solution bischofite. Probably, the high density of the solution and the presence of soluble salt MgCl2creates a braking effect.

Mixing time of Iodinol with an aqueous solution of bischofite in for 1 minute is optimal for this process.

The method of obtaining the raw material mixture for the manufacture of finishing and decorative building products, also in the first embodiment, includes mixing caustic magnesite with sawdust, moistening the mass aqueous solution of bischofite with pre-mixed in the amount of 0,3-0,6 OBC the Iodinol, the final mixing. A distinctive feature is that the mixture in an amount of 0.25 to 0.4 OBC crystals of the mineral carnallite with sizes from 2 to 10 mm add immediately after final mixing of the main components of the mixture and stirred no more than 1.5 minutes.

Mixing time for a period of not more than 1.5 minutes is optimal is determined visually depending on the volume of the mixture.

The method of obtaining the raw mix for the production and finishing of decorative panels, the main building products, the second option involves the mixing of caustic magnesite with sawdust, moistening the mass aqueous solution of bischofite, the final mixing. New in the proposed method of obtaining the raw material mixture, the second option is that entered in the mixture in an amount of 0.25 to 0.4 OBC crystals of the mineral carnallite size from 2 to 10 mm add immediately after final mixing of the main components of the mixture and stirred for a period of not more than 1.5 minutes.

Methods of obtaining raw material mixture can be carried out on known equipment for the preparation of mixtures, for example in the mixer SB 162.

The Iodinol - liquid dark blue color with a characteristic odor, foaming when shaken. The composition of Iodinol - crystalline iodine, potassium iodide, polyvinyl alcohol, water. The main active ingredient of Iodinol is molecular iodine, which has antiseptic properties. He has a bactericidal effect.

With the introduction of the mixture of Iodinol in the amount of 0,3-0,6 about. including the density of an aqueous solution of bischofite corresponds to the density of 1.12-1.18 g/cm3. The increase in the number of Iodinol reduces the density of the solution bischofite and consequently degrades the performance properties of the mixture, and reducing the number of Iodinol less than 0.3 vol. h h is give the desired effect of increasing the separation of ions of iodine.

The excessive secretion of Aharonov magnesium and bromine is achieved by the fact that in the raw material mixture further added carnallite crystals with a size of 2 to 10 mm 0,25-0,4 about. PM

As you know, the magnesium chloride in nature is the basis of such minerals as bischofite and carnallite, solutions which are used to obtain magnesia cement. These solutions serve as a source of ions of magnesium and bromine.

When preparing the raw material mixture to 65% of the injected solution of magnesium chloride from the solution participate in the reaction with caustic magnesite. And only the remaining amount can participate in the process of ionization.

Introduction in the mixture is additionally put into the form of crystals can significantly increase the effect of air ionization due to the fact that the carnallite crystals have a lower rate of emission of ions than the aqueous solution of carnallite. In addition, carnallite in the form of crystals has a lower reactivity than the aqueous solution, so the crystals practically do not participate in the chemical reaction with caustic magnesite and remain in the form of crystals in the hardened mass.

With the introduction of a mixture of carnallite crystals in the amount of about less than 0.25. including a slight increase in aarnisalo, and more than 0,4 about. 'clock impair its performance. Crystals menee mm under stirring absorbed by the solution bischofite, and crystals larger than 10 mm reduce the strength of the mixture.

As part of carnallite are isomorphic admixture of bromine in the amount of 0.2%. Bromine, not as a crystalline substance, distributed throughout the volume of the material, carnallite in intergranular spaces. In addition, carnallite is a complex salt containing mechanical impurities other salts, clay substances and rocks, formed over a substantial period of time. Mechanical impurities, clay material and rock are the shell, which creates a braking effect to highlight bromine through the smallest pores. Given the hygroscopicity of carnallite in the premises in which the product of the proposed mix, you can increase or decrease the humidity to increase or decrease the speed of separation of the bromine. The number of bromine 0.2% in the carnallite is not low, since its release is in the form of ions.

The resulting raw mixture suggested ways to create a new material, conventionally called "AZ-Salt".

From this material released batch of tiles, which is used for the manufacture of wall panels, elements of the lattice of partitions, table wares, etc. These products are used in children's entertainment rooms, bedrooms, halls of activities with the aim of creating a healthy atmosphere is very. They are recommended for use in workplaces with computers and other electronic equipment to enhance content in the air of negative ions.
