Pigment production and problems encountered in the processing of the industry involved:
1. Pigment is easy to flocculate and settle;
2. Large particle of raw material will cause damage to printing plate;
3. The wettability of the pigment is poor, so the moisture and air in the pigment particles cannot be replaced;
4. Due to the uneven dispersion of pigment, it affects the coloring power of ink and the brightness after drying.
Benefits of adding pigment dispersants:
1. Destroy the flocs in the pigment;
2. Improve the fluidity, coverage, rheology and color development of ink;
3. Make the pigment disperse more evenly, improve the chroma and glossiness of the product;
4. Improve the wettability of the pigment, and smoothly replace the air and water between particles through the wetted powder;
5. Disperse large raw material particles and small particles, which will not cause damage to the scraper and blocking plate in the printing process.
Characteristics of pigment dispersant:
1. Good dispersibility, simple and convenient use, and small dosage;
2. Effectively accelerate the project progress and improve the production efficiency;
3. Good dispersibility, simple and convenient use, and small dosage;
4, soluble in water, with alkali resistance and high temperature performance, less foam.
