Description
Technical field
The invention belongs to non-ferrous metal surface processing technology field, is related to a kind of surface treatment side of non-ferrous metal workpiece
Method.
Background technology
The non-ferrous metal prepared by different metal surface treatment process, surface property differ widely.Use at present
Many treatment process for surface of nonferrous metal include the modes such as pickling, polishing, sandblasting, and still surface is shaded after processing, and efficiency is low,
And the bad processing of complexity workpiece, there are its defect and limitation.
Traditional industry is all that each unlike material needs different inorganic agents to carry out, and cost is high, process length.Simultaneously
Continuity in scale removal process due to production is poor, increases disposal of pollutants load；And a period of time after its cleaning, workpiece need
Again clean, anti-microbial property is weak, and corrosion resistance is relatively low when long-term use of, and surface easily changes colour, and influences the outward appearance of metal works and is
Using effect.
The content of the invention
It is an object of the invention to provide a kind of surface treatment method of non-ferrous metal workpiece, solves current non-ferrous metal table
The problem of face changes colour, corrosion resistant erosion degree is low.
The technical solution adopted in the present invention is a kind of surface treatment method of non-ferrous metal workpiece, specifically according to following
Step is implemented：
Step 1, by pending workpiece carry out chemical polishing；
Step 2, by step 1 gained workpiece with surface conditioning agent soak 10-15 minutes；
Step 3, by step 2 gained workpiece carry out drying and processing；
Step 4, by step 3 gained workpiece carry out anodized；
Step 5, step 4 gained workpiece polished.
The features of the present invention also resides in：
Chemical polishing is the HNO for using mass concentration to be 10% for 5% HF and mass concentration in step 13The change of composition
Optical polishing liquid；
The component and mass percent of the surface conditioning agent used in step 2 for：Corrosion inhibiter 11%-15%, surface-active
Agent 11%-18%, antioxidant 0.05%, silica 1 5%-20%, water are surplus；The corrosion inhibiter include nonox,
Monoethanolamine, diethanol amine, triethanolamine, BTA, lignosulfonate, the surfactant are non-ionic surface active
Agent, including AEO, NPE and Tween 80, the antioxidant are sodium citrate, sulfurous
Sour potassium, sodium sulfite；
Drying uses industrial drier in step 3, and temperature is 130 DEG C -150 DEG C；
Polishing is carried out using grinding machine or emery wheel in step 5.
The invention has the advantages that form layer of silicon dioxide diaphragm in non-ferrous metal surface so that non-ferrous metal
Workpiece has good hydrophily and protection, reduces the corrosion rate of non-ferrous metal surface, keeps the light of non-ferrous metal surface
So that workpiece is readily cleaned in use while pool is spent, the surface comprehensive performance of non-ferrous metal is lifted.
