I. Description: 

 1, the product quickly at room temperature iron phosphating solution can be formed in the surface of the iron and steel, zinc, aluminum thickness of 0.8-1.2um, yellow red and blue color coating, electrophoretic coating, powder coating has an excellent supporting film resistance to bending, resistance to deformation, strong adhesion. 

 2, the single liquid, stable performance, almost no sediment, bath easy management, consumption of low-cost, large capacity. 

 Second, the process parameters: 

 1, total acidity, 8 - 12:00 

 2, the liquid acid :1-2:00 

 3, the processing temperature: room temperature 

 4 ways: spray or immersion 

 Third, the process: 

 Degreasing → washing → rust → washing → washing → washing → drying → phosphide 

 Fourth, the maintenance of: 

 1 to 1 ton slot count each add 1 degree of phosphating agents the 1.3KG increase the total acidity. 

 2, the processing liquid temperature is below 15 degrees Celsius, the need to extend the time. 

 3, the working fluid in the processing of the workpiece surface area will be little white floc, this time should bath deposition together with the 1/3 of sediment removal, re-addition of fresh phosphating solution back to normal.
