The reasons for the mold and blackening of aluminum profiles with frames

Compared to previous stainless steel, aluminum alloy frames have the advantage of being less prone to oxidation and blackening. However, sometimes improper operation can also cause blackening. In order to better use aluminum alloy frames, the editor has summarized the following reasons for blackening of aluminum alloy frames: the reasons for mold and blackening of aluminum profiles on frames.

1. External factors: Due to aluminum being a reactive metal, aluminum alloy frame profiles are prone to oxidation, blackening, or mold under corresponding humidity and temperature conditions. Therefore, when storing profiles, attention should be paid to the influence of the surrounding environment

2. Improper cleaning: Due to the strong corrosiveness of some cleaning agents, improper cleaning operations create conditions for mold growth and accelerate the formation of mold

3. Many manufacturers do not perform any cleaning treatment or incomplete cleaning after processing the program, which can leave some corrosive substances on the surface of the aluminum alloy frame and accelerate the mold growth of the frame

4. Different storage heights of aluminum alloy frame profiles in the warehouse can also cause oxidation and mold growth

There are many reasons that can cause aluminum alloy frames to mold and turn black. In daily use, as long as you pay attention to the above points, you can greatly extend the service life of aluminum alloy frames
