Surface treatment of stainless steel railings
Stainless steel balustrade with its surface bright, not easy to rust and other advantages, by the vast number of consumers welcome. There are many kinds of surface treatment methods for stainless steel railings. The following types are common:
1. Surface specular brightness treatment
According to the complexity of the stainless steel railing products and user requirements is different respectively by mechanical polishing, chemical polishing of stainless steel, stainless steel electrochemical polishing stainless steel and other methods to achieve bright luster.
Ii. Surface coloring treatment
The surface coloring treatment of stainless steel railings is mainly realized by the following methods:
Chemical oxidation coloring; Electrochemical oxidation coloring; High temperature oxidation coloring method; Gas phase cracking coloring method; Ion deposition oxide coloring.
3. Whiten the surface color
In the process of processing stainless steel balustrade, the black oxide skin is produced after the coiling plate, binding edge, welding or the artificial surface is heated by fire. At present, there are two main treatment methods for oxide skin:
Chemical method: a pollution-free acid-washing passivating paste and a normal temperature non-toxic cleaning solution with inorganic additives were used for washing, so as to achieve the purpose of whitening of stainless steel. This method is suitable for large and complex products.
Sand blasting: the main method is to use the micro-glass beads to remove the surface of the black oxide skin.
