When many users buy aluminum plates, they can see that a lot of aluminum plates will be coated with a protective film on the surface, so why should the surface of the aluminum plate be coated? Mainly because the texture of aluminum is relatively soft, it is easy to scratch and scratch.

The role of aluminum plate protective film:

1, in fact, the special purpose of the protective film are much the same, the aluminum plate protective film is also a special purpose to avoid scratches, and the performance of the mobile phone protective film is the same, but the price of the aluminum plate protective film is lower, and the cost price of the ordinary aluminum plate protective film per square meter is about 1-2 yuan.

2, the protective film mainly plays a role in avoiding the aluminum plate in the cutting, bending and other processing problems, of course, only the hardness of the mild scratch problem, if it is a sharp object scratch then the aluminum plate protective film can not play a protective role.

Thickness of aluminum plate protection:

Usually, the thickness of the aluminum plate protective film is 3-5 wires, and the higher the price of the aluminum plate protective film after the thickness is about, the better the effect of avoiding scratches

Therefore, after the surface of the aluminum plate is coated, the situation of the aluminum plate being scratched can be avoided to a large extent, whether it is in the process of transportation or loading and unloading, it has played a very big role.

The role of the pattern on the aluminum roll?

With the development of economy, the market application of aluminum coil is more and more extensive, and the patterned aluminum coil is one of the more commonly used, and the process of the patterned aluminum coil is relatively complex, which also creates the good anti-slip function of the patterned aluminum coil. So what is the role of the pattern on the aluminum roll?

The patterns above the patterned aluminum rolls are for beauty, and these patterns not only have decorative functions, but also play a role in anti-slip in some special cases.

Production process of pattern:

1, extrusion: aluminum plate manufacturers will heat the good round casting rod in the mold extrusion, extrusion using air-cooled quenching and artificial aging process to complete the heat treatment, the heat treatment strength of different models of products is not the same.

2, smelting: Put the good raw materials in the furnace according to customer requirements for smelting, and then through the process of degassing and slag removal, the impurities and gases in the material are disposed of.

3, casting: under the appropriate casting conditions, the refined aluminum liquid cooling cast into various specifications of the round casting rod.

4, ingredients: according to the detailed consumption of aluminum plate alloy number to calculate the amount of each alloy, and then with a more reasonable raw material.

5, coloring: the aluminum profile must be oxidized before coloring, but the corrosion resistance of the plate after oxidation is usually weak, so it must also go through the anodizing process to ensure the performance of the plate.
