Water-based and solvent-based inks required for preparation of nano-pigments

In recent years, pigment-based ink jet technology acclaimed, primarily due to pigments and dyes generally performed better compared to water and light fastness. The current inkjet market, ink manufacturers and producers are increasingly demanding filling ink pigment pastes, including preparation, including a simple solution. Just added to the formulation of several of these additives and the "magic ingredient" ink jet printing can be made to meet the stringent requirements of high-performance ink jet printing. The following will explore both aqueous and solvent inks require fine pigment preparation.
Aqueous inkjet ink must elect one kind of match with the desired color hue pigments. The water, dispersing agent and other additives such as pigment powder or wet cake was added after the mixing of the homogenized material and wet the pigment surface. Then the aggregates and agglomerates of the pigment particles are composed of a bead mill, a microfluidizer, or other suitable dispersing manner to that of primary particles. Because the space between the molecules and the dispersion or electrostatic repulsion, native particles become very stable. The resulting pigment slurry was filtered, and by addition of water, a co-solvent (wetting agent), and other ingredients such as antimicrobial agents, chelating dilution. It must be emphasized, used in the first step of the pigment dispersed pigment channel technology influence. Metal soap
Chemical properties of the dye characteristics are affected primarily by impact modifier , and pigment properties are mainly affected by the chemical and physical parameters. Therefore, in addition to explore new dispersants and other optimization dispersion to prepare a pigment physical properties such as particle size distribution, surface charge and polarity, structure, especially the purity of modern inkjet printing technology is to obtain the pigment preparation of the desired key. Final preparation and properties required for the ink such as transparency, color, viscosity, storage stability and the print head without friction and so can be optimized to achieve the effect. Water-based ink is mainly used for office, for inkjet printing is also appealing.
