1、 This kind of drying mainly depends on the absorption of paper and the penetration of ink. The mechanism can be explained as follows: because paper is a porous material made of fibers, the pore size is very small. When the ink is transferred to the paper, due to the capillary effect of the paper fiber gap, it begins to absorb the binder in the ink. In the absorption process, the composition and rheological properties of the ink gradually change, the liquid component of the ink gradually decreases, the cohesion of pigment particles increases gradually, and the ink gradually loses its fluid properties and presents a solid form. 2、 Oxidative conjunctiva drying is the use of oxidative polymerization to change ink from liquid to solid. The mechanism is: the dry vegetable oil in the ink contains unsaturated double bond, which is synthesized by peroxide bridging polymerization. During the induction period of drying, the oxidative polymerization reaction of dry vegetable oil is very slow because of its small amount of phospholipid organic antioxidants. When the antioxidant is destroyed, dry vegetable oil absorbs oxygen and reacts with oxygen to form hydrogen peroxide. Because hydrogen peroxide is very unstable, it can be separated into two free radicals under light, one of which is carboxyl oh. As the chemical properties of the free radical are very active, when it attacks another oil molecule, a new free radical is produced. The original free radical will form a stable compound. The small molecules of the oil are then polymerized into macromolecules until there is no double bond. Ink becomes a polymer network structure of the dry solid film. 3、 The drying form of evaporation drying depends on the solvent volatilization in the ink binder to make the remaining resin and pigment form a solid film and fix on the substrate surface. Mostly used for gravure ink. The rate of evaporation drying mainly depends on the latent heat of solvent evaporation, the proportion of pigment, the radius of particles and different kinds of resin. 4、 Radiation drying refers to the drying form in which the ink changes from liquid to solid by polymerization of the molecules of the binder by the energy of radiation. Including: A: UV drying. b: Electron beam drying. c: Infrared drying. d: Microwave drying. e: Wet coagulation drying, condensation drying, precipitation drying, filtration drying, etc.
