Hello,everyone,today we will talk about the analysis of galvanized steel appearance treatment technology 
  Steel strip as steel strapping machine' consumables,. Galvanized steel expping equirements are more stringent, especially for galvanized steel appearance processing requirements. Today Ausense engineer give us galvanized steel exterior processing technology analysis.
   In the normal work environment, the thickness of galvanized layer of hot galvanized strip up to more than 50 um, can be used safely for 30 years due to the anodic protection effect of iron matrix, pure zinccoating hot dip galvanizing steel strap surface can generate a denselayer in the atmosphere, the passivation of zinc basic carbonate [Zn2(OH) 2CO3] protective film further blocked zinc corrosion. However, due to zinc is a kind of amphoteric element is lively and pH were reaction, also can be heavy metal ion replacement of salts, so galvanized in wet pH or salt medium layer is easy to destroy, cause corrosion perforation. Therefore, in view of this situation, suggest that the surface of galvanized steel processing, such as asphalt coating, or seal groove, the direct contact of the isolating medium and zinc layer. This helps the galvanized strap function, to ensure safety in service. Good maintenance method can prolong the life of galvanized steel strapping tool.
