FIELD: heating.

SUBSTANCE: proposed method of arranging a multilayered ice cover for curling envisages formation of an ice underlayer characterised by enhanced hardness and similar to monocrystal ice in terms of structure and slip properties. Initially one provides for freezing on a lower adhesive layer at least 1 mm thick with admixture of a composite in an amount no more than 50 ppm which is represented by water suspension of polytetrafluorethylene and/or a tetrafluorethylene-hexafluorpropylene copolymer and/or perfluordecaline. Then follows the underlayer formation by way of successively freezing on several clear (containing no admixtures) ice layers each no more than 1 mm. After that one provides for freezing pebble embossments onto the underlayer using water with a temperature no less than 60 C; the pebbles contain admixtures of ammonia in an amount from 0.1 ppm to 100 ppm and water suspension of polytetrafluorethylene and/or a tetrafluorethylene-hexafluorpropylene copolymer and/or perfluordecaline in an amount from 50 ppm to 100 ppm.

The invention relates to the creation of artificial ice for Curling and can be used to create artificial platforms for this game. Ice Curling is a very solid and smooth ice the underlying cause, which manually from a special vessel water is sprayed. Frozen on a flat surface of ice water droplets called pebble. The result is a surface uniformly covered with asperities on which glides's stone. In contrast to a smooth surface sliding on ice with printed pebble more manageable and allows the team to more accurately perform the game maneuvers.

However, when applying pablow of normal water, even past all the stages of purification, pebbly istirahat before the end of the game period. Thus, the object of the invention is to design and create a method of producing a multilayer ice Curling, where the lower part (map) has a high hardness and structure and slipperiness close to monocrystalline ice, and pebbly have a great time wear and continue until the end of the game.

In the prior art there are several ways to obtain a multilayer ice coatings with additives. For example, a method of obtaining ice, according to Oromo in the water before freezing impose high molecular weight polymer polyox in the number of 10-10 wt.% (inventor's certificate SU 444039, F25 3/02, 25.09.74).

The disadvantages of this method of producing artificial ice include the following:

1) the polymer is introduced into an array of ice reduces its hardness,

2) on the surface of the ice formed local bumps, ripples, rippling,

3) the use of high molecular weight polymer is difficult because of its poor solubility in water.

These drawbacks have been eliminated upon receipt of a two-layer ice (Goncharova GU and other Secrets of the ice Palace. // Refrigeration technology, No. 5, 2005, p.10-13), one layer of which (the bottom) has a high hardness to prevent deep penetration of the blade of the skate in the ice, and the other (upper) layer - soft was introduced impurities. As impurities were used film-forming amines, composites plant-based, Vodopyanova solutions.

However, ice obtained by the above method, however, does not have a sufficiently low coefficient of friction, and pebbly caused by the spraying of water of the same composition quickly abraded and the end of the game the ice surface becomes smooth, without regular relief that worsen the conditions of the game and the accuracy of the "stone".

A method of obtaining a multilayer ice, suitable for Curling, which is obtained by the integration is Finance icy underlay, with increased hardness and the structure is close to the single-crystal ice (patent RU No. 2274810 from 10.02.05).

The technical result of the invention is to increase the time save the resulting patterns of ice cover, which is provided by applied to solid ice underlying cause of Pablo special composition, which in turn have a great time wear.

The technical result is achieved by the fact that the claimed method of obtaining a multilayer ice Curling, including the formation of ice underlay, with increased hardness and structure and sliding properties similar to single-crystal ice, characterized by the fact that first must be lower adhesion layer with a minimum thickness of 1 mm with the addition of not more than 50 ppm of composite aqueous suspension of polytetrafluoroethylene and/or a copolymer of tetrafluoroethylene with HEXAFLUOROPROPYLENE and/or perpendicular, then form the subbase by successive numerazione few pure without additives layers of a thickness not exceeding 1 mm each, on the subbase with water temperature of at least 60C must be modified tabs - pebbly containing added ammonia in an amount of from 0.1 ppm to 100 ppm and an aqueous suspension of polytetrafluoroethylene and/or a copolymer of tetrafluoroethylene with HEXAFLUOROPROPYLENE and/or perf orderlin in an amount of from 50 ppm to 100 ppm.

In addition, the use aqueous suspension which has passed the low-temperature vacuum cleaning chemical compounds that impair the smoothness of the ice surface.

Also used to retrieve ice water is subjected to a preliminary cleaning and deep deaeration.

The application of the adhesive layer with the specified parameters is necessary to prevent the possibility of detachment of the ice array.

As additives for the deposition of the adhesion layer is selected aqueous suspension of polytetrafluoroethylene and/or a copolymer of tetrafluoroethylene with HEXAFLUOROPROPYLENE and/or perpendicular in an amount of from 1 ppm to 50 ppm.

As additives for the formation of pablow selected ammonia in an amount of from 0.1 ppm to 100 ppm and an aqueous suspension of polytetrafluoroethylene and/or a copolymer of tetrafluoroethylene with HEXAFLUOROPROPYLENE and/or perpendicular in an amount of from 50 ppm to 100 ppm.

The choice of these intervals following reason. The authors of the invention in the process of research found that the introduction of additives in the adhesive layer is within the specified limits of concentrations was not observed delaminations ice array and there were no cracks in the formation of ice array. When forming the modified pablow with additives aqueous suspension of polytetrafluoroethylene and/or a copolymer of tetrafluoroethylene with HEXAFLUOROPROPYLENE and/or perfo decalin of at least 50 ppm and not more than 100 ppm and ammonia in an amount not less than 0.1 ppm and not more than 100 ppm, the sliding properties of the obtained surface increases, while the period of wear and "erase" Pablo increases significantly.

Choose the upper limits due to the achievement of the desired level of hardness and wear resistance of Pablo and ice sliding properties of the underlying cause.

The choice of the lower limit values defined minimum number of additives to obtain a technical result.

In addition, the authors of the present invention determined that use of the additive aqueous suspension of polytetrafluoroethylene and/or a copolymer of tetrafluoroethylene with HEXAFLUOROPROPYLENE and/or perpendicular more than 100 ppm leads to greater softening and penetration into the lower layers, thus losing hardness.

The authors of the invention in the process of research found that the addition of ammonia in the amount specified in the freezing pablow provides an additional increase in hardness Pablo and very stable increase of the sliding properties. So the introduction of such additives (in combination with other claimed additives) creates the conditions for obtaining and long-term preservation of the specific surface of ice for Curling with the best physical and mechanical properties compared with all known analogues.

It should be noted that the use of additives in the Noah suspension of polytetrafluoroethylene and/or a copolymer of tetrafluoroethylene with HEXAFLUOROPROPYLENE and/or perpendicular in the stated quantities, providing a positive impact on the quality of the ice, however, is very low concentrations of the trace that are not only tangible organoleptic person, but does not affect his health, as evidenced by compliance with the stated amounts of additives sanitary requirements for sports facilities.

Pre-cleaning and deep water deaeration is an additional condition for obtaining a smooth defect-free, without the inclusion of air bubbles of ice.

Another condition is to observe the temperature for water at the freezing modified Pablo: when filling in a special filling device using water at a temperature of at least 60C, which is important for reducing the speed of crystallization of ice.

The method illustrates the drawing, which shows:

1 - solid monolith, comprising the adhesive layer and the underlying cause,

2 - pebbly,

3 - clean layers of thickness up to 1 mm each,

4 - level markup

5 - adhesion layer.

Used to fill the water through the purification system by passing it through a mass filter and activated carbon, and also went deep deaeration.

Pre-treatment of water included the following main stages:

cleaning from mechanical impurities (filter);

lighten and remove chlorine using activated charcoal;

- softening (removal of hardness salts in the ion exchanger);

- demineralization up to 98-99% (reverse osmosis);

- removal of dissolved gases by vacuum and thermal deaeration;

- UV disinfection.

After cleaning, before the introduction of additives water had a value of conductivity 5-7 s/cm-1pH to 7.8, dissolved oxygen, up to 1 mg/L.

Formed the underlying cause by successive numerazione pure without additives layers with a thickness of 1 mm each.

The map was generated with increased hardness and the structure is close to a single crystal ice.

On the subbase with water temperature of 65C was namasagali modified tabs - pebbly containing added ammonia in the amount of 100 ppm and a water suspension of a copolymer of tetrafluoroethylene with HEXAFLUOROPROPYLENE in an amount of 100 ppm.

Example 3 implementing the inventive method

The conditions for ice remained the same as in example 1 except that the modified tabs - pebbly contained additives of ammonia in the amount of 30 ppm and a water suspension of a copolymer of tetrafluoroethylene with HEXAFLUOROPROPYLENE in an amount of 70 ppm.

Example 4 implementing the inventive method

The conditions for ice remained the same as in example 1 except that the modified tabs - pebbly contained additives of ammonia in the amount of 15 ppm and a water suspension of a copolymer of tetrafluoroethylene with HEXAFLUOROPROPYLENE in the amount of 80 ppm.

The conditions for ice remained the same as in example 1, the drop is observed in that was namasagali lower adhesion layer thickness 1, 2mm with the addition of 35 ppm composite - aqueous suspension of a copolymer of tetrafluoroethylene with HEXAFLUOROPROPYLENE, then formed the underlying cause by successive numerazione few pure without additives layers with a thickness of 0.95 mm each.

The map was generated with increased hardness and the structure is close to a single crystal ice.

On the subbase with water temperature of at least 70C was namasagali modified tabs - pebbly containing added ammonia in a quantity of 50 ppm and perpendicular in the amount of 0.2 ppm.
