How To Choose Enamel Pigments?

In the current fierce market competition, the appearance of enamel products is also an important part of product competitiveness, especially for daily enamel products. In terms of color selection, chromium oxide green, cadmium selenium sulfide (cadmium red), cadmium sulfide (cadmium yellow), melanin, etc. are all commonly used enamel pigments, so for enamel manufacturers, when purchasing enamel pigments, you need to pay attention What technical parameters? 

1. Chromium oxide (chrome green): The chrome green in the enamel pigment requires a Cr2O3 content of ≥97%, all of which pass 200 mesh, and have acid and alkali resistance.

2. Selenium cadmium sulfide / cadmium sulfide selenide (cadmium red): The cadmium red pigment needs to have light resistance and atmospheric resistance, temperature resistance above 600 ℃, and all pass 200 mesh.

3. Cadmium sulfide (cadmium yellow): The appearance of cadmium yellow pigment is light yellow or orange powder.

4. Milk yellow pigment: It needs to have light resistance and atmospheric resistance, temperature resistance above 600 ℃, and all pass 200 mesh.

5. Pink pigment: Appearance is pink powder, no water-soluble salt, light resistance and resistance to atmospheric influence, temperature resistance above 600 ℃, all pass 200 mesh.

6. Coffee pigment: no water-soluble salt, with light resistance and atmospheric resistance, temperature resistance above 600 ℃, all through 200 mesh.

7. Sky blue pigment: It needs to have light resistance and atmospheric resistance, temperature resistance above 600 ℃, and all pass 200 mesh.

8. Melanin: no water-soluble salts, with light resistance and atmospheric resistance, temperature resistance above 600 ℃, all through 200 mesh.

When enamel manufacturers buy enamel pigments, they need to check the color of the products. The effect of adding enamel pigments to the enamel base glaze should be basically the same as the standard sample brand to avoid color difference.
