1, surface treatment of aluminum surface treatment at present mainly in the following categories: electrostatic spray, paint, roller, roller pearl, film. Where the electrostatic spray, paint, roller, roller pearl, film. Where the electrostatic spray, paint manufacturers short life aluminum magnesium alloy, prone to chromatic aberration, roller, roller board pearl centered life, no color, can be divided into ordinary film faced plywood imports of magnesium and aluminum alloy film prices, general Compared with the life of the film roll plate to be low, and the life of the film basically imports reached 20 years does not change color. What factors need to be considered selecting aluminum? Aluminum material currently on the market are the following: the origin divided by aluminum ordinary aluminum, wide aluminum, SWA; in accordance with international labels such as aluminum is divided into 1100,3003,5005 label; by aluminum The strength of the alloy into H24, H18, etc.; according to the toughness of aluminum into ordinary aluminum, magnesium alloy, aluminum-manganese alloy. Now on the market ceiling materials are used in the most ordinary of aluminum, which is characterized by low intensity, the general flatness, toughness, not deformed. Without a good base, will greatly affect the life of aluminum. Magnesium alloy aluminum factory | magnesium alloy aluminum | aluminum rolls provided by the Aluminum Co., Ltd. Jinan rolls.
