Benefits of technology

This patented technology makes it easier for manufacturers to make stronger or longer-lasting metal products with better performance without generating harmful chemicals during their production processes. It also reduces environmental concerns associated with producing these materials due to its low amount of acids used compared to traditional methods like electroplating techniques that use strong bases such as hydrochloric acid (HCl). Additionally, this new material improves the overall durability of the product while reducing costs through improved efficiency when making them faster than older technologies.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the durability and effectiveness of zinc coating on metal surfaces during manufacturing or use thereof due to its excellent resistance against corrosive agents like water vapor that can attack it over time causing rusting damage.

Embodiment 1

[0018] The invention discloses a preparation method of galvanized iron wire steel strip, the specific steps are as follows:

[0019] (1) Surface pretreatment of iron wire and steel strip: including degreasing, derusting and rough treatment. Among them, the degreasing method is soaking in sodium hydroxide or potassium hydroxide solution with a mass concentration of 40%, and then rinsing with clean water , and then rust removal, the rust removal method is to soak in hydrochloric acid or nitric acid solution with a mass concentration of 40%, rinse with water after soaking until the surface is neutral;

[0020] The rough treatment method of iron wire is sandpaper grinding, and the rough treatment method of steel strip is sandblasting with quartz with a particle size of 1.0-1.2mm. The sandblasting treatment process conditions are: voltage 20V, current 150A, spraying distance 140mm, atomization Gas pressure 0.5Pa;

[0021] (2) Arc spraying: Use pure zinc wire with a diameter of 4-5...
