摘要： The invention refers to the field of surface cleaning from deposits of different nature, namely, to the surface cleaning means for metal, ceramic surfaces of industrial equipment and can be used for removal of such deposits as metal oxides (iron, chrome, nickel, etc.), carbonate and salt deposits, asphaltene-resin-paraffin and oil deposits, organic and biological (bacterial) deposits. The claimed solution for removal of deposits of different nature comprises the hydrogen peroxide, chelating agent, anti-foaming agent water-soluble calixarene and water at the following ratio, % wt.: hydrogen peroxide, catalyst for decomposing peroxide compounds, anti-foaming agent, chelating agent, water-soluble calixarene and water at the following ratio, % wt.: hydrogen peroxide 2-35; catalyst for decomposing peroxide compounds 2-20; chelating agent 3-10; SAA0.1-5; anti-foaming agent 0.01-1.0; water-soluble calixarene 0.01-1; water - remaining part. Technical result is the increased efficiency of the cleaning solution (degree of cleanliness) for surfaces contaminated with deposits of high organic content, with simultaneously increasing scope.

摘要： The invention relates to cleaning deposits of various natures from metal, glass and ceramic surfaces of industrial equipment and can be used for the removal of such deposits, as metal oxides (iron, chromium, nickel, etc.), carbonate and salt deposits, asphalt-tar-paraffin deposits and deposits of an oily nature, deposits of organic and biological nature (bacterial deposits). The proposed solution for removing deposits of different natures comprises hydrogen peroxide, complexing agent, calixarene and water in the following quantitative ratio, wt. %: hydrogen peroxide, 2 - 90; complexing agent, 3 - 30; calixarene, 0.01 - 10; water, the balance. EFFECT: increased degree of cleaning off deposits of various natures with simultaneous reduction of solution aggressiveness to structural materials.
