Description
Technical field
The present invention relates to the polishing technology field of aluminum products more particularly to a kind of chemical polishing solution for aluminum products and use the throwing
The polishing method of light liquid.
Background technique
The chemical polishing of aluminum products is the selectivity being produced in acid or alkaline electrolyte solution using aluminium and aluminium alloy
From dissolution, to reduce the chemical processes of its surface roughness, PH.Chemical polishing has energy consumption small, easy to operate, raw
High-efficient, the advantages that not suffering from the product shape and size restrictions is produced, is in the processing of aluminum products surface finishing and its important process.Tradition
Surface with chemical polishing technology generally use phosphoric acid, sulfuric acid, nitric acid cooperation " three acid " technique, have quality of finish good, brightness height etc.
Advantage, but due to the use of nitric acid, have a large amount of tobacco (i.e. nitrogen oxides) generation during the polishing process, cause serious environment
Pollution, endangers operator's health significantly.
Research of the country to aluminum products without tobacco chemical polishing probably starts from the 1980s, achieve some achievements,
But from the point of view of total situation, the polishing brightness (reflectivity) of no tobacco polishing not enough, cannot reach the bright of traditional three acid polishing
Degree and production requirement.Therefore, no tobacco surface with chemical polishing technology is above limited by very large in application.
In addition, the bad main cause of spue line that the anodic oxidation of existing aluminium extruded type material occurs: mold bridge location designs not
It is good, it repairs a die, extrusion ratio discomfort etc., processing method major way are as follows: preceding workshop section's change, the die change tune of aluminium extruded molding procedure
Whole, this mode is at high cost and effect cannot be completed to prevent, and is unable to satisfy the market demand.
Summary of the invention
It is high that the purpose of the present invention is to provide a kind of polishing brightness, and pollution-free, spue line is uniform, can meet market need
The chemical polishing solution asked and the polishing method using the polishing fluid.
To achieve the above object, the present invention is achieved by the following technical programs:
A kind of chemical polishing solution for aluminum products, the following composition including accounting for mass percent: phosphoric acid 68%~70%, sulfuric acid
15%~25% and corrosion inhibiter 10~15%.
Further, the corrosion inhibiter is anhydrous cupric sulfate.
Further, the mass concentration ratio of the phosphoric acid is 85%.
Further, the mass concentration ratio of the sulfuric acid is 98%.
A kind of polishing method using chemical polishing solution for aluminum products, includes the following steps:
S1, the aluminum products polished are placed in the alkaline degreaser that temperature is 60~65 DEG C and impregnate 15~30S
After take out, and rinsed well with tap water；
S2, the aluminum products after step S1 are placed in temperature it being in 105~115 DEG C of polishing fluid, polishing time is 10~
15S is rinsed well with tap water later；
S3, the aluminum products after step S2 are placed in neutralizer, the neutralization time is 3~15S, is rushed later with tap water
Wash clean.
In conclusion compared with prior art, the present invention has the advantages that following substantive distinguishing features outstanding and significant:
(1) polishing fluid of the invention is after reducing the ratio of phosphoric acid and sulfuric acid, then adds copper sulphate, it is possible to reduce 30% is left
Between when the light out on the right side, accelerates light action out, the consumption of surface aluminum substrate is reduced, to reach the luster effect of product；
(2) spue line caused by also solving the problems, such as because of corrosion depth relatively depth can meet the market demand；
(3) polishing process of the invention is simple, required at low cost and pollution-free.
