The main components of the phosphating solution is the dihydrogen phosphate, such as Zn (H2PO4) 2 and a suitable amount of free phosphoric acid and acceleration and the like. Accelerator mainly from the lower temperature and speed phosphate phosphate Speed. As with most chemical accelerator oxidants such as NO3-, NO2-, CIO3-, H2O2 and so on. Metal phosphating process is dilute phosphoric acid or acid phosphate to form the phosphate is reacted with a protective film. Phosphate solution composition in general, phosphate supplements, phosphate modifier, phosphate accelerator consists of several parts phosphide slotted agent (phosphate built bath agent), which slotted agent and supplements for major components: open groove agent is first built tank used supplements are supplements to build tank after use; phosphate modifier phosphate solution is to adjust the total acid and free acid, in order to achieve a suitable acid ratio; phosphating accelerator is an oxidant, The main depolarization promoting phosphating reaction speed.
