In the process of daily use of aluminum castings, we must carry out appropriate maintenance on the castings on time, otherwise it will be too late to maintain them after cracks occur in the castings, which will reduce the service life of the aluminum castings. Therefore, it is very important to maintain aluminum castings on time. So how to carry out effective maintenance?
1. The room where aluminum alloy castings are stored should be kept dry, free of dust and environmental pollution, and the air humidity can be within 50%.
2. Remove dirt from the objects before entering the warehouse. Good things are chemically protected. Do not apply thick grease or oil on the crafts. Wear cotton gloves when touching the crafts.
3. Use soft cloth, soft brush, soft duster, etc. to remove dust on aluminum alloy castings.
4. If you need to wash by hand, use distilled water, or heat the distilled water, and use neutral soap. Do not use ammonium hydroxide, acids, white powder, gauze, etc. If there is no major cleaning, it can be cleaned by professional technicians.
5. The original method for cleaning copper and aluminum alloy crafts is to apply a layer of chemical protective agent or a layer of paraffin after heating. The modern method is to apply a layer of silicone sealant to prevent harmful substances and moisture damage.
6. To prevent mechanical damage to objects, do not place them next to each other.
7. Try to observe the changes in aluminum castings. Once the symptoms of aluminum disease are found, they should be handled in time. The method can be cleaned with sodium sesquicarbonate (5% sodium carbonate + sodium bicarbonate) until there is no chloride ion.
The above is the maintenance method of aluminum castings. I hope it will be helpful to you after reading it.
