Abstract
The invention relates to a cleaning process/method and particularly relates to a cleaning process/method for an aluminum alloy material. The cleaning process/method comprises the steps: oil seal removal; washing; chemical oil removal; washing; alkali washing; washing; acid washing; washing; drying; checking. The cleaning process/method is simple in process, convenient to operate, low in cost, little in pollution and capable of keeping the cleaned workpieces clean and bright so as to be an efficient cleaning process/method for the aluminum alloy material.
Description
Technical field
The present invention relates to a kind of cleaning process, especially a kind of cleaning process of aluminum alloy materials.
Background technology
Aluminium alloy is very easily oxidized, and oxidized aluminum alloy can generate the aluminum oxide film of one deck densification, and this causes aluminum alloy materials in following process, to produce many defects, thereby impact is used.Conventional clean program complexity, workpiece corrosion are heavier, cause aluminum alloy surface impaired.
Summary of the invention
The present invention is intended to address the above problem, and a kind of cleaning process of aluminum alloy materials is provided, and its method is simple, it is few to clean up, pollute, and its technical scheme adopting is as follows:
A cleaning process for aluminum alloy materials, is characterized in that, the step of described cleaning is followed successively by:
A) envelope of deoiling: remove the oil sealing on Al alloy parts;
B) washing: Al alloy parts is rinsed with a large amount of tap water;
C) electrochemical deoiling: the grease on Al alloy parts surface is dissolved by its solvent version;
D) washing: Al alloy parts is rinsed with a large amount of tap water;
E) alkali cleaning: at 60 ℃ of temperature, Al alloy parts is placed on to 4-5%(massfraction) sodium hydroxide solution in soak 1min, remove the oxide film on Al alloy parts surface;
F) washing: Al alloy parts is rinsed with a large amount of tap water;
G) pickling: under room temperature, Al alloy parts is placed on to 5%(volume fraction) salpeter solution in soak 10-15s;
H) washing: Al alloy parts is rinsed with a large amount of tap water;
I) dry: Al alloy parts is dried to bake out temperature 70-80 ℃;
J) check: check that whether Al alloy parts is bright and clean.
Tool of the present invention has the following advantages: its processing method is simple, easy to operate, and cost is low, pollution is few, and the workpiece of cleaning is clean, bright and clean, is a kind of cleaning process of efficient aluminum alloy materials.
