Aluminum alloy die casting Wholesale Price products are mainly used in electronics, automobiles, motors, home appliances and some communication industries. Some high-quality aluminum alloy products with high performance, high precision and high toughness are also used in large aircraft and ships. Industry. So how much do you know about the surface treatment of Aluminum alloy die casting Wholesale Price? Let's take a look at the knowledge of environmentally friendly chemically polished surfaces of aluminum and aluminum alloys!

It is determined to develop a new environmentally-friendly chemical polishing technology based on phosphoric acid-sulfuric acid as the base fluid. This technology must achieve zero emission of NOx and overcome the quality defects of similar technologies in the past. The key to the new technology is to add some compounds with special effects to the base fluid to replace nitric acid. For this reason, it is necessary to analyze the three-acid chemical polishing process of aluminum, especially the role of nitric acid. The main function of nitric acid in aluminum chemical polishing is to inhibit pitting corrosion and improve polishing brightness. Combined with the chemical polishing test in pure phosphoric acid-sulphuric acid, it is believed that the special substances added to phosphoric acid-sulphuric acid should be able to inhibit pitting corrosion and slow down general corrosion, and at the same time, it needs to have a better leveling and brightening effect.
The above is a brief introduction to the surface treatment knowledge of Aluminum alloy die casting Wholesale Price.
