The Basic Production Process Of Metallic Ink

The following is the basic production process of metal ink: copper, aluminum, zinc raw materials ➝ melting, atomization ➝ sieving ➝ grinding ➝ sieving ➝ filter press ➝ mixing ➝ the biggest difference between the production process of metal ink and ordinary ink It is the preparation process of metallic pigments, especially the grinding process. Since aluminum pigments are explosive during the grinding process, a wet grinding process must be used. In addition, metallic ink uses the reflection of metal flake particles to achieve metallic luster. In order to ensure a good mirror reflection effect, the grinding process of metallic pigments is gentler than that of ordinary pigments to avoid damaging the shape of the metallic flakes. Pay attention to the choice of additives during the grinding process. Using different additives can produce two types of metal inks, floating or non-floating. The former has good metallic gloss, but poor adhesion and wear resistance, and cannot be colored. Although the latter has poor metallic gloss, it has good adhesion and wear resistance, especially good colorability. Users should choose floating or non-floating products according to actual needs. This is very important, otherwise it will affect the performance of post-processing and final products.
