Causes of mould and mildew in aluminium alloys and how to deal with it

Aluminium is a metal structure material with excellent electrical and thermal conductivity and corrosion resistance, and is widely used in industry. Due to the recent complex weather changes and high air humidity, especially in Beijing, the storage requirements for aluminium are relatively high, but there is still mould and corrosion, so why does mould occur? Here is an analysis of its causes for you.

1、The environment in which the aluminium alloy products are kept, the temperature and humidity are suitable for mould growth.

2, the surface of aluminium alloy products mixed with super sister material, automatically absorb moisture into the air to form a primary battery corrosion reaction, creating an environment suitable for the growth of mould.

3, aluminum alloy products surface, there are grease, plant fibres and other suitable soil for mould growth, once the humidity and temperature are suitable, mould growth is rapid.

4, aluminum alloy due to the original battery corrosion reaction, the surface precipitation of alkaline compounds quality, moisture solution after the temperature and humidity is suitable for mold growth rapidly.

Prevention and treatment of aluminium alloy mould.

1, the product can not be stored in the open air for a long time, the surface of the textile products flying dust accumulation.

2、Do not use the refining deterioration slagging agent containing sodium salt or magnesium salt, use the refining deterioration agent of NaF composition, or N2 gas refining.

3, not using release agents containing vegetable fibres, not using machining cutting fluids containing vegetable fibres and replacing oil-based anti-rust cutting fluids.

4, stacked on the marquee of the product packaging cartons to be wrapped with winding film 6 sides of good waterproof, the product has been stained with water need to be placed in the ventilation blow dry.
