Abstract
The invention discloses an environment-friendly metal rust removing solution which comprises components in parts by weight as follows: 80 parts of water, 40-60 parts of straw ash, 20-30 parts of citric acid and 2-5 parts of acetic acid. According to the environment-friendly metal rust removing solution, the straw ash adopting a porous structure is applied to the rust removing solution, and under the combined action of the citric acid and the acetic acid, the rust removing solution has a good rust removing function for metal, especially has the excellent rust removing effect on steel type metal, causes low damage to mechanical properties of the metal and is safe and environment-friendly during operation.
Description
Technical field
The present invention relates to a kind of metal-derusting liquid.Be specifically related to a kind of environment-friendly metal rust removing solution.
Background technology
Get rusty easily under metal (as: steel) is placed in outdoor or open-air condition, not only affect visual appearance, also can affect normally carrying out of techniques such as spraying paint, bonding, as processed not in time, more can cause scrapping of material, causing unnecessary financial loss.
Traditional chemical rust removing uses strong acid usually, acid can with iron rust and 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, and the oxide skin of Hydrogen Energy to iron rust and indissoluble produces pressure, be conducive to their reduction with high price iron of peeling off, accelerate 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 form acid mist simultaneously, 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 novel environment-friendly metal rust removing solution.
Technical solution of the present invention is: a kind of environment-friendly metal rust removing solution, comprises following component: water, straw ash, citric acid, acetic acid.
As preferred further: each component is respectively by weight: 80 parts, water, straw ash 40-60 part, citric acid 20-30 part, acetic acid 2-5 part.
As preferred further: described straw ash forms by pulverizing after agricultural crop straw Thorough combustion, and particle is less than 50 μm.
As preferred further: this rust removing solution manufacture craft is, after fully being mixed by straw ash, adds citric acid and acetic acid successively, abundant stirring and evenly mixing with water.
Beneficial effect of the present invention is: first the straw ash with vesicular structure is applied to rust removing solution, under the acting in conjunction of citric acid, acetic acid, to metal, there is good rust removing function, especially to the rust cleaning excellent of steel metal, meanwhile, little to the mechanical property damage of metal.
