Functions and Uses：
1. DU-16 can take replacement with the alkaline degreasing and acid pickling so the two processes are combined in one.
2. It can completely remove the oil dirt and smut caused by the forging and welding and therefore reduce the defectiveness. With the excellent degreasing ability, the time DU-16 takes to remove greasy dirt is shorter than that of just hydrochloric acid pickling.
3. It effectively shortens the process to save the cost.
4. Those wash-off waste are easy to manage and the metal degradation can be done just by neutralization.
5. It is add-in type. The concentration of the hydrochloric acid and DU-16 can be adjusted in according to the treatment of pollutants and process
