In the choice of
aluminium checker plate manufacturers to buy aluminium, we are most worried about is the quality and price. Like aluminium, a lot of layman to watch the pattern of aluminium manufacturers do not understand the surface and material. So what kind of aluminium plate the best quality? The following pattern aluminium manufacturers give you the best explanation.
What kind of
aluminium tread plate is the best quality?
1. The inspection of the logo
Usually we see the aluminium checker plate manufacturers are marked, and the logo is a product of the standard code and license.
2. Check the surface quality
In addition to the surface of the aluminium manufacturers to see the clean or not, we need to see more things, such as we should look at whether there is some cracks in the aluminium sheet or the emergence of some corrosion phenomenon, these are careful The ability to observe.
3. Thickness of oxide film
This is the need to use a professional eddy current thickness measurement equipment for testing.
4. The quality of the hole
The formation of the sealing hole is formed after the anodic oxidation, if these seals are not well handled, it will lead to the subsequent phenomenon of aluminium sheet corrosion. Usually we are the method of detection is the acid leaching method is to remove the surface amount of dust, the nitric acid drops to the surface, after a gentle wipe, the water washed away nitric acid, and then drops on the surface of purple syrup, a minute after the paint clean See if there are obvious traces of the surface, if any, then the seal is not handled well.
5. Corrosion resistance
Aluminium checker plate manufacturers this indicator is also affecting the life of aluminium checker plate, we often use the method of sub-alkali, the use of sodium hydroxide solution, mainly to see the oxide film through the time. It is recommended that you have strict requirements in the laboratory.
