At room temperature and efficient multi-functional treatment agent (color film Four in One) 

 Adjustable four are new concept products can be controlled by the three groups were free to adjust to the four-in-one oil, rust phosphating various links. It can be used through the scrub, soak the heavy oil, remove the surface oxide, and to the formation of uniform color phosphide film, suitable for large workpieces brushing construction and site limited equipment manufacturers soak. 

 An approach: the use of scrubbing or Dip. 

 Second, the use of agents:

 "Four in One" DC # 286 
 Colorless or yellowish-brown solution 
 1.15 ± 0.05 
 550 ~ 700 


 , Phosphating treatment tank material: 

 Phosphide slot should be stainless steel, thick-walled plastic plate or carbon steel (anti-corrosion lining) system. 

 "Four treatment processes: 

 Work - → four-in-one treatment solution - → dry 

 , Four in the preparation of the working fluid (according to 1000 liters, dipping way preparation): 

 1, the water added to 60% of the empty slot; 

 2, to join the four-in-one treatment agent 330 kg, and stir to dissolve evenly; 

 3, make up the margin of water to 1000 liters and stir well; 

 Note: If the way to scrub preparation, according to a 1:4 preparation of the working fluid. 

 Six conditions of use: 

 Temperature: 0 ° C or more processing time: 5 ~ 30 minutes (impregnated) 

 Seven performance indicators:

 Supplement and adjust (Dip handle 1000 liters): 

 Continuous concentration changing, so the proper conduct of the work of the bath, add can add the appropriate amount to maintain the working fluid in a better working state, the general continuous treatment less effective.
