This invention relates to the field of washing and cleaning agents, in particular washing and cleaning agents for removing scale from the heating elements and the inner surfaces of washing machines. Water coming from natural sources in system domestic water contains hardness salts (mainly carbonates and bicarbonates of calcium and magnesium). Upon heating this water to high temperatures and especially when it is in contact with the surface of the heating elements is a selection of hardness salts with education on all surfaces washed by water, stubborn sludge - scale. The water supplied to industrial power plant such as boilers, are subjected to special treatment, which can remove a large part of hardness salts. In washing machines (household and industrial) uses tap water with salts of rigidity, which leads to the rapid formation of scale on all internal surfaces and especially on the surface of the heating elements. Scaling affects the heat transfer, which leads to failure of the heating elements. In addition, intensive contact erasable products with scale affects the texture of the tissues and reduces their strength. In this regard, the problem of removing scum no doubt. Submitting is shining most of the known washing and cleaning agents for removing scale presents acidic compounds with a low pH of their aqueous solutions. One of the earliest mentions of such media containing urea and hydrochloric acid or citric and maleic acids, refers to 1968 (Ajanovic. Chemical commodities, M., "Light industry", 1968, p.57-58). In the following patent publications available for descaling a number of washing and cleansing compositions based on various acids, in particular acetic and adipic acid (USSR Author's certificate No. 633896), sulfuric acid (USSR Author's certificate No. 768807 publ. 1978), organic dicarboxylic acids (USSR Author's certificate No. 697558 publ. 1979), phosphoric and organic phosphonic acids (Patent USSR No. 1829967, publ. 1993), sulfamic acid (Japanese patent No. 5050095, publ. 1993), phosphonic acid and organic dicarboxylic acids (Japanese patent No. 6154790, publ. 1994), formic acid and one or more carboxylic acids (U.S. Patent No. 5529637, publ. 1995), sulfuric and phosphoric acids in combination with ethylenediaminetetraacetic acid and sodium tripolyphosphate (Patent PRC No. 1144780, publ. 1997), ascorbic and ethylenediaminetetraacetic acid (Patent of Russia №2114215, publ. 1995), an organic acid in combination with hydrogen peroxide and surfactant (Canadian patent No. 2276165, publ. 1999), sulfuric acid, in combination with ethoxylated surfactants (French patent No. 2774371, publ. 199,), ethylenediaminetetraacetic acid and polimolekuly acid (Japanese patent No. 2000-154996, publ. 2000), hydrochloric acid (Patent of Russia №2265671, publ. 2005), sulfamic, nitrilotriethanol acids in combination with ammonium chloride and thiourea (Patent of Russia №2213069, publ. 2003). Above washing and cleaning agents when dissolved in water to form acidic solutions, well and quickly removes scum, but has a corrosive effect. High corrosive power of these resources excludes the possibility of their application for removal of limescale in washing machines. Publications related to washing and cleaning agents, which form when dissolved in water is neutral or slightly alkaline solutions, are able to remove the scum and do not attack the surface to be cleaned, very scarce. In particular, in the Patent PRC No. 1290741 (publ. 2001) offers a washing and cleaning agent for removing scale, which includes sodium hydroxide, sodium chloride, aluminum powder, sodium tripolyphosphate, and surfactant. The test composition proposed in this patent, showed that the process of removing scale from the interior surfaces of the washing machine requires a lot of time, and featured high norm makes it unprofitable. In the other Patent PRC No. 1546401 (publ. 2004) offers a washing and cleaning agent for removing scale, which consists of silica, sodium carbonate, sodium tripolyphosphate, salt of an alkali metal, in particular sodium chloride and alumina. Cost to use this composition is not suitable, because the authors recommend pre-listed components subjected to sintering at 1000-1500°C. The ideas contained in the above patents PRC, developed in the patent of Russia №2259392 (publ. 2005). Washing and cleaning agent described in this patent contains anionic surfactant, sodium tripolyphosphate, sodium carbonate, sodium chloride, sodium sulfate, ethoxylated Nonylphenol and some specific supplements are only necessary when washing clothes. We conducted tests of this tool (reproduced without specific additives) showed that solutions of this tool does not corrode any of the internal surfaces of the washing machine and well remove the scum. The only drawback of this tool, we have adopted as a prototype of this invention is that the efficiency of removing scale formed after three months of operation of the washing machine, not exceed (single treatment) 70%. To eliminate this drawback is proposed in composition among the STV, containing surfactant, sodium tripolyphosphate, sodium carbonate and sodium chloride, to enter the zeolite or bentonite and additionally sodium salt of ethylenediaminetetraacetic acid as a surfactant to use ethoxylated 8-10 moles of ethylene oxide Nonylphenol. Below is the proposed ratio of components, wt.%:
The technical result of the use of the proposed structure is in a significant increase of efficiency of scale removal from all internal surfaces and heating elements of washing machines. After a single processing cycle of the washing machine offered by the tool is removed up to 95-98% of the formed scale. The technical result is achieved by the fact that the washing and cleaning agent for removing scale from the heating elements and the inner surfaces of tyranny machines, containing surfactant, sodium tripolyphosphate, sodium carbonate and sodium chloride, further comprises a zeolite or bentonite and sodium salt of ethylenediaminetetraacetic acid as a surfactant is ethoxylated 8-10 moles of ethylene oxide Nonylphenol. Below is a brief description of zeolite and bentonite, the introduction of which into the composition of the proposed tools is its main distinguishing feature. Zeolite is a mineral of volcanic origin with high adsorption and ion exchange properties. All zeolites consist primarily of galantaminenoxide mixed with small amounts of clay and feldspar. When dehydration of zeolites form a fine crystal sponge with a pore volume of about 50% of the total volume of the mineral. Zeolites are thermally stable, chemically and mechanically hours, do not contain toxic compounds. Bentonite is dispersed clay with high binding and adsorption ability. Mineralogicheskii all bentonites include montmorillonite, salonic, napravit and baudelet. Origin is volcanic. Bentonites are good sorbents and capable of swelling in aqueous solutions. Does not contain toxic substances. Technology of preparation of the proposed means and means-FR the type shown in Example 1; methods of evaluating the effectiveness of removing scale in Example 2; the results of experiments on the removal of sludge in Example 3. Example 1. Technology of preparation of the proposed means of the prototype. The proposed tool and the tool prototype was prepared in an amount of 10 kg each in a laboratory drum mixer with a capacity of 20 kg Pre-method triturate preparing a mixture of parts of sodium tripolyphosphate ethoxylated with 8-10 moles of ethylene oxide with Nonylphenol (Neonol AF 8-10). The mixture was prepared manually in a porcelain bowl in the following way: 0.2 kg of neonols was mixed with 0.4 kg of sodium tripolyphosphate. To this mixture was added 0.6 kg of sodium tripolyphosphate and received 1.2 kg of the mixture was added 1.2 kg of sodium tripolyphosphate. After thorough mixing, the mixture containing 0.2 kg of neonols and 2.2 kg of sodium tripolyphosphate were loaded into the mixer. Then the mixer was consistently downloaded 2.8 kg of sodium tripolyphosphate, 3.0 kg of sodium carbonate, 1 kg of sodium chloride, 0.7 kg of zeolite or bentonite and 0.1 kg of sodium salt of ethylenediaminetetraacetic acid (trylon B). The tool prototype was prepared by the same technology in accordance with the recipe shown in the description of the Patent of Russia №2259392 taken as a prototype. In this process we used the following components: anionic surfactants, in particular alkylbenzoic Thonet sodium, sodium tripolyphosphate, sodium carbonate, sodium chloride, ethoxylated Nonylphenol (neonol AF 8-10), sodium sulfate and liquid glass. Other components (carboxymethylcellulose, polycarboxylate, optical Brightener and perfume), which is needed in the Laundry in the composition prepared means the prototype is not included. The duration of mixing upon receipt of the proposed means of the prototype was 2 hours. Example 2. Methods of evaluating the effectiveness of descaling For testing 20 samples prepared aluminum foil size 50×50 mm each, and 20 samples of stainless steel mesh sizes 20×20 mm hole size is approximately 2×2 mm Prepared samples foils and meshes separately weighed on an analytical balance with an accuracy up to the fourth digit, getting the total initial weight of the sample foil (Mof) and the total initial weight of the sample grid (Modwith). The weighted samples are artificially covered with scum. To do this, they were immersed in a glass heat-resistant glass, which was filled with a solution containing 0.5 DM3drinking water, 2.0 g of calcium carbonate, 2.0 g of magnesium carbonate and 0.2 g of iron sulfate. The solution was lowered and the stirrer at slow (30 min-1) stirring the solution was evaporated on a sand bath almost the DOS is and. Then the samples foil and mesh was transferred into a porcelain Cup and dried to constant weight in a drying Cabinet at 110°C. the Samples foil and mesh separately weighed to the fourth decimal getting a lot of samples with foil scale (Mfand a lot of samples with grid scale (Mwith). A lot of scum on the foil (Mnfand a lot of scale on grids (Mnwith) received by the formulas accordingly Mnf=Mf- Mofand Mnwith=Mwith- Mowith. To assess the effectiveness of removing scale in drum standard automatic washing machine was filled with 200 g of the proposed investment (in one case with the zeolite, the other with bentonite) or 200 g of product prototype. Then put on 20 samples of foil and grid scale. The car was launched in native mode (without linen) and the treatment was conducted at 90°after full testing program, samples of foil and mesh was removed from the car, washed with running tap water and dried in a drying Cabinet at 110°C to constant weight. In the weighing result received weight cleaned from scale samples foil and mesh respectively Mof 2and Mowith 2. The number of remaining samples on the scale was calculated by the formulas: for foil Bridgef=Mof 2- Mofand for a grid Bridgewith=M is with 2- Mowith. The removal efficiency of scale in % separately for foil (EF) and separately for the mesh (es) calculated by the formulas:
