Abstract
The invention provides a yellow-fume-free aluminum alloy chemical polishing solution which comprises components in parts by mass as follows: 35-40 parts of phosphoric acid, 18-22 parts of sulfuric acid, 0.2-0.4 parts of tartaric acid, 0.2-0.4 parts of citric acid, 0.7-0.9 parts of ammonium sulfate, 0.2-0.4 parts of a non-ionic surface active agent, 1.5-1.8 parts of ethylene glycol, 0.2-0.4 parts of sodium borate and 1,000 parts of water. The chemical polishing solution is simple to prepare and high in polishing speed and polishing accuracy, yellow fume is not produced in the polishing process, and corrosion pits are not generated on the surface.
Description
Technical field
The present invention relates to a kind of without tobacco aluminum alloy chemically polishing fluid.
Background technology
Aluminium alloying optical polishing is by its selective autolyzing solution effect in acid or alkaline electrolyte solution, to reduce the chemical processes of its surfaceness, pH value.The advantages such as this finishing method has equipment and simply, not limits by product overall dimensions, and the high and tooling cost of polishing velocity is low.
Traditional aluminum alloy chemically polishing fluid has following shortcoming: nitric acid decomposes too fast, and a large amount of tobacco is seriously polluted, and processing cost is expensive, and time one length is oxidizable causes loss of gloss.
Summary of the invention
In order to solve problems of the prior art, the invention provides a kind of without tobacco aluminum alloy chemically polishing fluid.
The invention provides a kind of without tobacco aluminum alloy chemically polishing fluid, described chemical brightening solution is made up of each component of following mass fraction: phosphoric acid 35-40 part, sulfuric acid 18-22 part, tartrate 0.2-0.4 part, citric acid 0.2-0.4 part, ammonium sulfate 0.7-0.9 part, nonionogenic tenside 0.2-0.4 part, ethylene glycol 1.5-1.8 part, Sodium Tetraborate 0.2-0.4 part, 1000 parts, water.
Preferably, described chemical brightening solution is made up of each component of following mass fraction: phosphoric acid 38 parts, 20 parts, sulfuric acid, 0.3 part, tartrate, citric acid 0.3 part, 0.8 part, ammonium sulfate, nonionogenic tenside 0.3 part, ethylene glycol 1.6 parts, Sodium Tetraborate 0.3 part, 1000 parts, water.
Further, described nonionogenic tenside is poly(oxyethylene glycol) 400 or Polyethylene Glycol-600.
By each component mixing of formula ratio, stir, obtain chemical brightening solution of the present invention.
Chemical brightening solution preparation of the present invention is simple, and polishing is rapid, and produce without tobacco in polishing process, polishing precision is high, surperficial corrosion-free pit.
