Abstract
The invention provides a chemical polishing liquid with aluminum and aluminum alloy. The chemical polishing liquid comprises the following components in parts by weight: 4-5 parts of phosphoric acid, 1-2 parts of sulfuric acid, 0.2-0.4 part of tartaric acid, 0.04-0.06 part of glacial acetic acid, 0.2-0.4 part of non-ionic surface active agent, 0.15-0.18 part of ammonium sulfate, 1.5-1.8 parts of ethylene glycol and 250-280 parts of water. The chemical polishing liquid provided by the invention has the advantages that the preparation is simple, the polishing is rapid, no yellow smoke is generated in the polishing process, the polishing accuracy is high and no corrosion pittingis formed on the surface.
Description
Technical field
The present invention relates to a kind of aluminum and its alloy chemical brightening solution.
Background technology
Aluminum and its alloy chemical rightenning 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 aluminum and its alloy chemical brightening solution.
The invention provides a kind of aluminum and its alloy chemical brightening solution, described chemical brightening solution is made up of each component of following mass fraction: phosphatase 24-5 parts, sulfuric acid 1-2 part, tartrate 0.2-0.4 part, Glacial acetic acid 0.04-0.06 part, nonionogenic tenside 0.2-0.4 part, ammonium sulfate 0.15-0.18 part, ethylene glycol 1.5-1.8 part, water 150-180 part.
Preferably, described chemical brightening solution is made up of each component of following mass fraction: phosphatase 24 .5 part, 1.5 parts, sulfuric acid, 0.3 part, tartrate, 0.05 part, Glacial acetic acid, nonionogenic tenside 0.3 part, 0.16 part, ammonium sulfate, ethylene glycol 1.6 parts, 170 parts, water.
Nonionogenic tenside selects 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.
