| titleOfInvention | Composition of post treatment agent for metal surface treatment |
| abstract | In the present invention, zinc and zinc compounds, phosphoric acid and phosphoric acid compounds, nitric acid and nitric acid compounds, manganese and manganese compounds may be appropriately mixed without using nickel and fluorine in the phosphate chemical coating process of the surface treatment process. It is a method of improving the coating properties by using a post-treatment in water after diluting with water to form a phosphate on the surface by dipping or spraying the material metal (skin). Since the phosphate coatings in use in the past contain nickel and fluorine, it is difficult to remove nickel when treating wastewater, and additional costs are incurred due to the operation of additional various equipment and equipment. As it has to be done, the economic burden due to the consignment cost, etc., and the operational difficulties continue, and by applying post-treament, workplaces and workers minimize contact with toxic substances, reduce environmental pollution, and reduce nickel and fluorine. It relates to a method that can satisfy the conventional coating properties as an environmentally friendly zinc phosphate coating that is not used. |
