Note stainless steel screws to prevent rusting 4:00

stainless steel screwIs common in daily life fasteners during use, rust is a common phenomenon, but also let's annoyance, this will not only affect the aesthetic level, and it will affect the performance of stainless steel screws. So we use stainless steel screws must pay attention to the process in which the use of points.

      1, dust or metal particles heterogeneous attachments, in the humid air, the fixtures and stainless steel screws condensate, the two together into a micro-battery, causing the electrochemical reaction protective film is damaged, known that the electrical chemical corrosion.

      2, stainless steel screws surface adhesion organic juice (such as vegetables, soup, sputum, etc.), in the case of water oxygen to form organic acids, organic acids long is the corrosion of the metal surface.

      3, stainless steel surface adhesion containing acid, alkali, salts (such as wall decoration alkaline, lime water splash), causing localized corrosion.

      4, air pollution (such as those containing sulfides, carbon dioxide, nitrogen oxide atmosphere), the case of condensed water to form sulfuric acid, nitric acid, acetic acid solution point, caused by chemical corrosion.
