The invention is illustrated in the drawing, which schematically presents the production line cleaning paste for cleaning a solid surface on the basis of mineral sludge from a waste product of protein-vitamin concentrate.

Information confirming the possibility of implementing the claimed invention are as follows.

Net is based paste for cleaning a solid surface contains the following known components: sulfonic acid (alkylbenzenesulfonate sodium), soda ash, perfume, sludge waste production.

In the stated paste as a filler used mineral sludge from a waste product of protein and vitamin production. Mineral mud contains mainly nevadacalifornia the rest of the map. Physico-chemical characteristics of mineral sludge are presented in table 1.

To improve disinfection ability of pasta in its composition brine natural mineral bischofite (bishofit) formula MgCl₂·6N₂About density of 1.2...1.3 t/m³. Natural deposits of mineral bischofite according to geological exploration only in the Volgograd region are estimated at billions of tons. Mineral bischofite extract on the surface by dissolution of the water and pumping from wells. Mineral bischofite - hygroscopic. The composition of the samples of the brine leaching of bischofite produced in the fields of the Volgograd region in salt form are shown in table 2. Chemical analysis of samples of brine leaching of bischofite and the content of macro - and microelements (brine from wells No. 4-11 Gorodishche field) are presented in table 3. Analysis of samples bischofite brine from different fields are shown in table 4. The composition of bischofite brine, extracted within regional, is given in table 5. Declared pasta is made in the following ratio, wt.%: Sul is anal (alkylbenzenesulfonate sodium) - 3-5; soda ash - 10-20; odorant - 0,4-1,2; mineral sludge waste production of protein-vitamin concentrate 52-58; brine natural mineral bischofite - 4-6; water - the rest.

The sulfonic acid is introduced into the composition of the paste as a bactericide. He refers to the anionic surfactant to the group of alkylarylsulfonates. It is the product of alkylation of benzene fraction of olefins in the presence of aluminum chloride catalyst composed of a mixture of sodium salts of alkylbenzenesulfonic with alkyl residues predominantly normal structure containing 11-12 carbon atoms.

By the looks of the sulfonic acid - liquid paste yellowish-brown color. The content of sodium salts alkylbenzenesulfonic - 50-55%; sodium sulfate - about 60%; desulfuromonas compounds is about 1%. The sulfonic acid is highly soluble in water and alcohol.

The sulfonic acid in the recipe at the same time plays the role of a disinfectant component and the role of the surfactant-containing composition, good wetting and cleaning ability. In addition, the composition with him has a good pastos without the introduction of the formula water.

As the primary cleaning agent used recycled mineral sludge from waste production of microbial protein from carbohydrates oil obtained at stage n the production of nutrient solutions of salts. The formation of mineral slurry at Svetly Yar plant protein-vitamin concentrates (Volgograd region of the Russian Federation) is about 5000 tons per year. Physico-chemical and thermal characteristics of mineral sludge from the waste production of protein-vitamin concentrate and scouring pastes based on it are shown in table 6. The content of the identified chemical elements in dry sludge waste production of protein-vitamin concentrate is given in table 7. Recycled waste in this composition not only provide a cleaning effect, but also partially remove unpleasant food odors that remain on the dishes. To enhance the deodorizing effect of the used brine natural mineral bischofite, which simultaneously ensures the sanitation of dishes.

Entered into a paste flavoring gives it a flavor.

Technical measures pastes are shown in table 8.

As agents that enhance the cleaning ability of the surfactant due to despergiruemaya and emilyrose actions in the recipe entered sodium carbonate (soda ash). Soda ash technical, as a component of the paste must meet the requirements of GOST 5100 - 85.

Waste production of protein-vitamin concentrate, not used and going to the dump, in this composition scouring pastes are used in natural is ideal and does not require additional processing. The introduction of the scouring pastes other abrasives is not required. In these waste contains finely dispersed calcium oxide (15%), iron (up 44%), phosphorus (up 13%), potassium (to 4.5%) and nitrogen (up to 13.5%) (see table 7) with a particle size of 20-30 microns, which are a good abrasive. They are stretchy and contributes to the mechanical cleaning of contaminated surfaces. In addition, the phosphates are good detergent component. The content of other salts in the waste is low, and therefore completely harmless to humans.

Example. Prepare three recipes pasta (1, 2, 3 - see table 9) based on the waste production of protein-vitamin concentrate. This waste adds sulfonic acid, soda ash, odorant, brine natural mineral bischofite and water in amounts shown in table 9, and thoroughly stirred to obtain a homogeneous mass. Prepared formulations suffer in comparison with the known pastes "Sanita" and "Supercall". The test results of physical and mechanical properties are given in table 10.

The data in table 10 show that the developed pasta has advantages over known as cleans the surface from rust. In addition, the paste has a number of other properties, in particular disinfectant, and protects the surface from corrosion.

Due to the MgCl₂·6H₂O the bischofite brine pasta is active against bacteria causative agents of intestinal infections, tuberculosis, upper respiratory infections (diphtheria, scarlet fever and other), fungi of the genus Candida, dermatophytes and viruses (pathogens influenza and other acute respiratory viral infections, viral hepatitis, HIV, herpes, rotavirus gastroenteritis).
