Flux Agent For Iron RemovaL Regeneration

Flux Agent For Iron RemovaL Regeneration:   The previous process of hot-dip galvanizing is flux plating. The flux solution is a composite solution of zinc chloride and ammonium chloride, which can effectively assist in galvanizing and improve its quality. Process Description: In hot-dip galvanizing process, iron ions and hydrochloric acid(HCl) will be brought with to some degree when we put workpieces into flux solution after pickling and rinsing. With the increase of production cycle, the concentration of iron ions and hydrochloric acid in the flux solution will also increase, which will have implications for the galvanizing process. Firstly, it will increase zinc consumption, and secondly, it will have an impact on product quality. This plan adopts the method of oxidation precipitation to remove iron ions and hydrochloric acid. The reaction equation is as follows: HCl2+NH4OH=NH4Cl+2H2O 6FeCl2+H2O2=4FeCl3+2Fe (OH) 3 ⬇ (Sedimentation) Process standard…
