Double-headed Bolt Factory chemically cleans the oxide and deteriorated rust on the surface of the bolt during the production process. In order to expose the bolt surface to the root of the ordinary bolt, in this case, it can effectively improve electroplating, surface phosphate treatment, oxidation (black and blue), stretching treatment, calendering treatment, calendering treatment, anti-rust treatment, etc. deal with.
In daily life, chemical rust removal is the method we most need to use: rust removal. 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 cause "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.
In the face of this display situation, this method aggregates and quotes data, and has the following characteristics:
1. Under normal circumstances, the treatment effect is fast and good at ambient temperature.
2. Usually most of the media we use have the functions of penetration, dissolution, dispersion, crust peeling and rusting.
In this case, China Nut's hydrochloric acid descaling quality is good. The rust removal quality meets or exceeds the Swedish anti-corrosion standards.
