| titleOfInvention | Supplementary liquid capable of prolonging service life of hydrogen peroxide etching liquid |
| abstract | The invention belongs to the technical field of materials for chemical etching of metal materials, and particularly relates to a replenishing liquid capable of prolonging the service life of a hydrogen peroxide etching liquid. The supplementary liquid comprises 4-20% of ammonium persulfate, 8-30% of chelating agent, 4-20% of regulator, 2-10% of multifunctional additive and ultrapure water which enables the total composition to reach 100% relative to the total weight of the total composition. After the supplementary liquid is added into the hydrogen peroxide etching liquid which is close to failure after continuous etching, the service life of the etching liquid can be obviously prolonged again, the purpose of saving the use amount of the etching liquid can be achieved, the etching cost is obviously saved, and the method has great industrial popularization value. |
