Ink is a common printing consumable. As an important printing consumable, it mainly plays a printing role in the printing process. Although ink is more common, many people do not understand how to use it. Especially do not know how to dilute? How to dilute printing consumables? When starting to dilute, special thinner must be added to the new ink to achieve a suitable viscosity for printing. The correct dilution method is to slowly pour the solvent while stirring the ink, because the pigment particles in the ink are evenly distributed throughout the system by being encapsulated in the resin. If a large amount of solvent is used and rapidly diluted, the ink is subjected to this. After the impact, the uniformly distributed pigment particles are often exposed to the naked state, losing the desired gloss and transparency, and the printing effect is lowered. Printing consumables ink dilution notes: 1, solvency For different systems of ink, different types of solvents are required. Because not all solvents dissolve the same resin. The dissolution of the solvent by the solvent follows the principle of similar polarity, the principle of similar solubility parameters, and the principle of solvation. When designing a diluent formulation, the formulated diluent must be sufficient to dissolve the selected resin, taking into account cost and other factors. A good thinner formula will contain true solvents, co-solvents and thinners to achieve some balance. 2, viscosity For the same concentration of the resin solution, the lower the viscosity, the better. Thus, when the same application viscosity is reached, the solid content of the paint liquid is higher, so that the construction efficiency is improved, and the amount of solvent volatilized into the atmosphere is relatively small, and the pollution to the environment is light. The solvent has a great influence on the viscosity of the coating due to its solubility to the polymer and its own viscosity. 3, surface tension The surface tension of the solvent affects the surface tension of the coating. Surface tension is an important indicator in paints. Low surface tension is beneficial for the wetting and dispersing of the pigment, the wetting of the substrate, the leveling of the coating, the adhesion to the substrate, the atomization properties of the coating and the prevention of surface defects of the coating. positive effect. When designing a formulation, the surface tension of the solvent must be fully considered.
