Inhibition of ink drying the primary material is white oil, the so-called white oil is made up of light magnesium carbonate, stearic acid's oil mixed with water made of opaque white emulsion, and loose moisture absorption performance, and contains water, easy to cause ink appear emulsifying phenomenon, so as to prevent ink layer of polymerization process, dry ink effects. Veli oil is the main component of aluminum hydroxide, which is a kind of amphoteric hydroxide, not only its own does not have the drying, but also adsorption agent, and in water will have a certain degree of disaggregation, so will increase the emulsification of ink in the printing process, thereby delaying the drying time of ink.
Adhesive is also the most often added to the ink of a substance, it is made of wax and dry oil or petroleum jelly and dry oil, turpentine, etc. Due to dry the material itself is very slow, so only a small amount of used in ink, not affect to ink drying rate, but if too much with wax type of adhesive, on the one hand, will change the original structure, the ink makes the ink, plastic, on the other hand also can float on the surface of printing ink, block connection material produce the oxidative polymerization of membrane, thus affect the ink drying rate.
