Stainless steel railings with its bright surface, not rusty, etc., has been welcomed by the vast number of consumers. Stainless steel railings surface treatment methods have a variety of common are the following categories:
First, the surface mirror bright processing
According to the complexity of stainless steel railing products and user requirements can be different mechanical stainless steel polishing, chemical stainless steel polishing, electrochemical stainless steel polishing method to achieve the mirror gloss.
Second, the surface coloring
Stainless steel railings surface coloring mainly through the following methods to achieve:
Chemical oxidation coloring; Electrochemical oxidation coloring; High temperature oxidation coloring; Gas phase pyrolysis coloring; Ion deposition oxide coloring.
Third, the surface of the original bleaching treatment
Stainless steel railings in the process of processing, after Coil, Zha edge, welding or after artificial baking surface heat roasted, resulting in black oxide skin. Currently there are two main ways to deal with scale:
Chemical method: Use a non-polluting pickling passivation paste and non-toxic at room temperature with inorganic additives cleaning solution for dipping, so as to achieve the true nature of stainless steel whitening purposes. This method is suitable for large and complex products.
Sandblasting method: The main method is to spray micro-glass beads to remove the surface of the black oxide.
