The casting process of aluminum castings is actually a core technology mainly based on low-pressure casting of electromagnetic pumps, so the composite purification technology of aluminum smelting and forming, as well as the core technology of the entire manufacturing industry, produce high-quality aluminum castings in modern technology. In fact, aluminum castings may encounter some problems during their daily storage and use, such as the phenomenon of mold formation. Below, the editor will take you to understand why aluminum castings undergo mold formation.
Firstly, there are issues with the environment in which aluminum castings are stored, such as not being too dry and having relatively low humidity and temperature, making it more suitable for mold growth, ultimately leading to mold growth in the aluminum castings.
Secondly, during the casting process, the surface of the aluminum casting contains super dissolved substances. If this is the case, it will automatically absorb moisture into the air, leading to a corrosion reaction in the original pool. This creates a more suitable environment for mold growth.
Once again, due to the corrosion of the original battery on the aluminum casting, alkaline compounds precipitated on the surface. After deliquescence, the humidity and temperature were relatively moderate, which led to the rapid growth of mold.
Afterwards, oil and plant fibers appeared on the surface of the aluminum castings, which are suitable environments for mold growth. If the temperature and humidity are just right, the mold will grow quickly.
