Another reason for the formation of agglomerated plugs and crystal crowns in ballpoint pen inks is the oxidation of brass and the interface, and the production of copper and zinc compounds in the solution. The antioxidant contains substances that can absorb and absorb surrounding oxygen, so it can effectively prevent oxidation. The combination of antioxidants and corrosion inhibitors can more effectively prevent or inhibit the corrosion of copper alloys. Experiments show that the antioxidants we use are effective good. In the experiment, we also used an anti-desiccant. The main function is to prevent the oxidative drying of the ink surface or ink marks, so that the ink and ink marks have a better visual effect, and at the same time extend its service life and retention period, and can also improve the ballpoint pen's performance during application. Performance, anti-drying agent is also an antioxidant.
