Steel cold rolling wastewater special agent 1, the company specifically for steel cold rolling wastewater treatment independent research and development of high-tech products. The agent can effectively improve the interfacial tension of the cold-rolled waste film in the steel mill, so that the colloidal particles in the sewage can not lose the repulsive force and attractiveness, and finally lose the stability to form the floc, and further through the chemical bridging, In the separation of oil and water and other toxic and harmful impurities, shorten the separation time, can be miscible with water, and in a wide range of pH value.
