Embossed aluminum sheet is an aluminum commodity that produces various lines on the surface after calendering processing on the basis of aluminum alloy sheet. It is widely used, and the key is used in packaging, engineering construction and building curtain wall. So how to detect the quality of metal drawing of the pattern aluminum sheet? This article will introduce how to test the drawing quality of embossed aluminum sheet.

1. Identification inspection: Usually people see the pattern aluminum sheet is equipped with identification, and the identification is the specification number and license certificate of the commodity.

2. The thickness of air oxide film: This must be tested by eddy current thickness measuring instrument.

3. Surface quality inspection: In addition to the surface of the pattern aluminum sheet to see whether cleaning, people must see a large number of items, such as people should see the aluminum sheet is not there are some cracks or some erosion, this is only to be found by careful observation.

4. Sealing quality acid leaching method: The generation of the sealing hole is produced after the anodic oxidation treatment, if the sealing hole is not very good solution, it will cause the corrosion of the aluminum sheet after the situation.

People to carry out the inspection way is the acid leaching method, that is to say after remove the dust on the surface of the sodium cyanide drops into the surface, to gently scrub, tap water wash sodium cyanide, drops of crystal violet, on the face to wipe the surface to clean after a minute, look at the surface is a significant mark, if you words that hole sealing no problem very well.
