The relationship between structure and dispersion of surfactants
- 2023-09-22 17:26:36
- admin
Water dispersion system is commonly used to analyze the relationship between surfactant structure and dispersion.As a hydrophobic solid particle, it can adsorb the hydrophobic group of the surfactant, and if it is an anionic surfactant, the outward-facing hydrophilic genes have the same charge and repel each other. Obviously, the adsorption efficiency of surfactants increases with the increase of ...

Ink resin coloring power
- 2024-03-08 17:34:54
- admin
Organic pigment is the most basic material to provide color to the ink, but as the ink attached to the surface of the substrate, the color shown to the consumer often produces more or less deviations from the color of the pigment itself. The reason is that in the ink, the pigment particles do not exist alone, but are dispersed in the connecting material medium. Microcosmic, the best wetting disper...
