Abstract
The invention discloses a fast detection method of an aluminum anode dark line. The method comprises that after the anodic alumina plate is washed by alkali and pickled, the anodic alumina plate is put into a triple acid mixture solution to be etched, then the anodic alumina plate is put into a camera obscura and tested by bright light. The fast detection method of aluminum anode dark line is easy to operate, after treatment for 10-20 minutes, the aluminum anode dark line can be quickly detected by naked eyes, and the detection result is accurate.
Description
Technical field
The present invention relates to a kind of method for quickly detecting of aluminium anode concealed wire.
Background technology
Concealed wire be aluminium section bar in extrusion process because the slag inclusion or impression of material internal cause, it is carried out in aluminium section bar
Directly detection is difficult to before oxidation, needs the operation such as Jing alkali cleanings, pickling, neutralization, powered anode after oxidation that defect could be allowed to manifest
Out.Therefore, time-consuming for the characterization processes of current aluminium anode dark line, high cost, affects very big to production efficiency.
The content of the invention
For the problems referred to above, the invention provides a kind of method for quickly detecting of aluminium anode concealed wire, at its Jing short time
The quick naked eyes that aluminium anode concealed wire is capable of achieving after reason are detected.
For achieving the above object, the present invention is adopted the following technical scheme that：
A kind of method for quickly detecting of aluminium anode concealed wire, it is comprised the following steps：
1）Alkali cleaning：Anodic oxidation aluminium plate is put in the NaOH solution that mass fraction is 8% ~ 12% and is soaked after 2 ~ 3min, taken out,
Rinsed well with water；
2）Pickling：Sheet material is put into into 0.5 ~ 2min of immersion in the hydrochloric acid solution that mass fraction is 5%, is taken out, rinsed well with water；
3）Three acid etch：By hydrofluoric acid, hydrochloric acid, nitric acid and water by volume 2:6:6:86 are mixed into three sour mixed solutions, then
By the sheet material after surface treated in three sour mixed solutions 2 ~ 3min of etch；
4）Inspection：Sheet material after etch is taken out, is rinsed well with water, then dried, in placing into camera bellows, using high light（Work(
The LED lamp source of rate ＞ 5W）Irradiation is tested.
The present invention enables aluminium anode concealed wire in strong illumination by alkali cleaning, pickling, three acid-etched fast version processing steps
Under present canescence fine strip shape, so as to can by naked eyes be detected, its whole process only needs more than ten minutes, compares traditional
Testing process（Nearly 45 minutes）Save time about 30min；Meanwhile, the inventive method is simple due to treatment process, and at normal temperatures
Processed, monthly 20,000 yuan nearly compared with traditional detection method escapable cost.Therefore, the present invention can the current aluminium sun of effectively solving
Time-consuming for very dark line characterization processes, high cost the problems such as, the value with good popularization and application.
Description of the drawings
Fig. 1 is using the concealed wire on the aluminium observed after the inventive method process.
