How to Distinguish Raw and Clinker from Aluminum Composite Panel?

The core material of the regular high-quality aluminum-plastic board is a non-toxic PE core material as required, but many Metal Composite Panels Factory use so-called raw materials in order to reduce costs. The distinction between plastic board and clinker aluminum-plastic board.

1. In terms of toughness

Due to the poor toughness of the raw material, the raw aluminum-plastic plate is easy to break, and the clinker aluminum-plastic plate has good toughness and is not easy to be broken.

2. Processing

When processing aluminum-plastic panels, raw materials may be more expensive. After all, there are impurities.

3. Advantages and disadvantages

When the aluminum skin is thick, the advantages and disadvantages of the two core materials do not appear on the surface of the construction effect. However, when the aluminum skin is thin, the finished aluminum-plastic board of the raw core material often has small protrusions, and the flatness is not flat. it is good.

4. Detection of core particles

According to the specific gravity test, the granules are placed in water, and the clinker is floating on it, otherwise it is raw.

5. Price of aluminum-plastic board

Due to the price difference of raw materials, raw aluminum-plastic board is much cheaper than clinker aluminum-plastic board.

With the development of process technology, the weight of aluminum-plastic panels in people’s lives is getting higher and higher, and the color is no longer monotonous as before. The current aluminum plate processing can color the color you want, but when we color the aluminum plate, we will inevitably encounter the situation that the color is not dyed. Then, the causes and treatment methods of the Aluminum Composite Panel are not dyed. :

Aluminum Composite Panel

1. Insufficient anodic oxidation film thickness: The solution is to check whether the anodic oxidation process is standard, and to see whether the temperature, voltage, and conductivity are stable. If there are abnormalities, please adjust the specifications accordingly. If there is no abnormality, you can extend the oxidation time appropriately. Guaranteed film thickness.

2. The pH value of the dyeing solution is too high: At this time, the pH value can be adjusted to the standard value with glacial acetic acid.

3. After the oxidation, the workpiece is left in the water tank for too long: it is recommended to dye in time. If this situation has occurred, the workpiece can be placed in the anodizing tank or the nitric acid neutralization tank and then activated. The dyeing will be very effective. it is good.

4. The dye has been decomposed or mildewed: At this time, the dye needs to be replaced and a suitable dye should be selected.

5. The oxidation temperature is too low, resulting in dense film: the oxidation temperature can be appropriately increased.

6. Poor electrical conductivity: Possibly poor electrical conductivity as indicated by poor anode copper rod or cathode lead plate contact. Pay attention to cleaning the anode copper rod and cathode lead plate to ensure good conductivity.

The above are the causes and treatment methods of aluminum plates that are not dyed. At present, aluminum plates have become common materials in the construction field, and they are widely used in decorative fields such as building exterior walls, interior walls, and advertising signs. However, as people have higher and higher requirements for the aesthetics of decorative articles, aluminum plates with single colors and dull patterns can no longer meet production needs.
