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. Next, Hex Nut Factory introduces how to remove rust reasonably?

1. In the face of rust, it can effectively improve electroplating, surface phosphate treatment, oxidation, stretching treatment, calendering treatment, calendering treatment, anti-rust treatment, and other treatments.

2. 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.

3. Under normal circumstances, the treatment effect is fast and good at ambient temperature. Generally, most of the media we use have the functions of penetration, dissolution, dispersion, crust peeling, and rusting. The quality of hydrochloric acid for descaling is good. The rust removal quality meets or exceeds the Swedish anti-corrosion standards.

Through the above introduction, China 2H Hex Nut Factory hopes that you can simply refer to the content of this article in future use.
