Abstract
The invention discloses de-rusting liquid capable of protecting a nonferrous metal casting. The de-rusting liquid comprises, by weight, 100 parts of water, 46-53 parts of sodium gluconate, 32-40 parts of natural pine oil, 11-16 parts of sodium carbonate and 2-5 parts of ethylene diamine tetraacetic acid (EDTA). The de-rusting liquid capable of protecting the nonferrous metal casting is alkalescent, has a protective effect on metal, avoids the phenomenon that metal becomes crisp after strong acid de-rusting, and nonferrous metal resources are saved.
Description
Technical field
The present invention relates to a kind of rust removing solution.
Background technology
Non-ferrous metal is the base mateiral of the national economic development, most industry such as Aeronautics and Astronautics, automobile, machinofacture, electric power, communication, building, household electrical appliances all with
nonferrous materialsfor production basis.Along with modern chemical industry, agricultural and scientific and technical advancing by leaps and bounds, the status of non-ferrous metal in human development is more and more important.It is not only important in the world
strategic materials, the important production means, and the important materials being the indispensable means of subsistence in human lives.
Traditional chemical rust removing uses strong acid usually, and acid can be with
iron rustand metal oxide generation chemical reaction, generate solubility salt, thus reach the object of rust cleaning, while rust cleaning, acid to react releasing hydrogen with underlying metal again, the oxide skin of Hydrogen Energy to iron rust and indissoluble produces pressure, is conducive to their reduction with high price iron of peeling off, accelerates the process of pickling.
But traditional acid solution treatment process also also exists obvious defect: namely in treating processes, the generation of a large amount of hydrogen can make steel produce Hydrogen Brittleness Phenomena, causes the mechanical properties decrease of metal, affects the intensity of iron and steel itself; Easily formed simultaneously
acid mist, affect the health of operator and corrode equipment around and environment; The consumption of acid solution is also comparatively large, increases processing cost; This kind of acid can form excessive erosion to steel.In addition a large amount of residue produced, need often discharge, both heavy corrosion industrial pipeline, again contaminated soil and environment.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of rust removing solution non-ferrous casting to defencive function.
Object of the present invention carrys out specific implementation by the following technical programs:
Non-ferrous casting is had to a rust removing solution for defencive function, each component by weight, 100 parts, water, Sunmorl N 60S 46-53 part, natural pine tar 32-40 part, sodium carbonate 11-16 part, EDTA2-5 part.
Preferably, above-mentioned metal founding of checking colors has the rust removing solution of defencive function, each component by weight, 100 parts, water, Sunmorl N 60S 48 parts, natural pine tar 35 parts, 12.5 parts, sodium carbonate, EDTA2.5 part.
Beneficial effect of the present invention:
Metal founding of checking colors provided by the present invention has the rust removing solution of defencive function, in weakly alkaline, metal is had to the effect of protection, avoids the phenomenon that becomes fragile after strong acid rust cleaning, has saved nonferrous metal resource.
