Precision aluminum parts generally require cleaning to not corrode the substrate, and can not affect the original bright color of the aluminum. Therefore, ordinary aluminum degreasing or aluminum acid removal and other low-grade aluminum cleaning agents cannot be used. "Aluminolysis" mainly uses acid as a raw material to release a gas by chemical reaction with an aluminum substrate, and gas is generated and discharged from the surface of the workpiece to separate the oil stain from the workpiece. However, the aluminum piece after the "aluminum acid removal" caused white alumina on the surface due to the chemical reaction, and the entire workpiece became white, losing the original bright color of the aluminum material, and the workpiece size also changed accordingly. Therefore, we recommend using a neutral aluminum cleaner for cleaning without reacting with aluminum, without affecting the original color and without affecting the size of the workpiece.
When used, it is mixed with water for 15-30 times and heated for use. The basic process recommendations are: ultrasonic cleaning - rinsing - rinsing - drying.
The main point of the cleaning agent is whether the aluminum cleaning agent is neutral or unsatisfactory, because it is well known that aluminum products, especially die-cast aluminum materials, often suffer from long-term mold problems during storage. On the surface, there is a white hairy substance, similar to mildew. If you remove the mildew, you will find gray or black spots underneath. This is a phenomenon in which the aluminum material has an oxidation reaction with aluminum on the surface during the storage process. Therefore, in addition to being neutral, the aluminum cleaning agent does not react chemically with the aluminum material, and is easy to rinse without residue. It should also have a protective effect on the aluminum material to enhance the anti-oxidation and anti-corrosion ability of the aluminum material itself in the subsequent inventory process.
