Products such as Aluminum alloy die casting Wholesale Price are mainly used in electronics, automobiles, motors, home appliances and some communication industries. Some high-precision and high-toughness high-quality aluminum alloy products are also used in industries with relatively high requirements such as large aircraft and ships. middle. The main use is still on the parts of some instruments. So how much do you know about its surface treatment knowledge? Let’s take a look at it briefly below!
1. Alkaline electropolishing process of aluminum
The research on the alkaline polishing solution system was carried out, and the effects of corrosion inhibitors, viscosity agents, etc. on the polishing effect were compared, and an alkaline solution system with good polishing effect was successfully obtained. , At the same time can improve the polishing effect of additives.

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