In the processing of stud products, it is necessary to chemically clean the oxide and deteriorated rust on the surface of the stud so that the surface of the stud is exposed to the root of the ordinary stud. In this case, it can effectively improve plating, surface phosphate treatment, oxidation (black and blue), stretching treatment, calendering treatment, calendering treatment, anti-rust treatment, and other treatments. Hex Bolt Manufacturers introduces the rust removal method of studs:
Although hydrochloric acid can quickly remove rust, it is also widely used because it is important to use it at room temperature. However, in actual operation, the descaling of hydrochloric acid can lead to "excessive corrosion" and "hydrogen embrittlement", and it is easy to release a large amount of acid mist, thereby causing specific environmental pollution and social harm.
Faced with this display situation, this method summarizes and quotes data, which has the following characteristics:
1. Under normal circumstances, the treatment effect is fast and good at ambient temperature.
2. Generally, most of the media we use have the functions of penetration, dissolution, dispersion, crust peeling, and rusting. In this case, the quality of hydrochloric acid for descaling is good.
