(1) The ratio of mixed solvent. The volatilization rate of mixed solvents is restricted by each other among solvent molecules, and its volatilization rate is not the average value of their volatilization speed.
(2) The influence of resin. The solvent volatilization in ink is more complex. When the resin dissolves the dry solvent, the molecules of the two substances are closely combined with each other (the role of solvent). At this time, the volatilization speed of solvent is lower than that of solvent itself. A certain viscosity of liquid ink, in the drying process attached to the solvent volatilization, resin content in the increase, the solvent volatilization speed will also slow down.
(3) Condition of pigment particles. When making ink, when pigment, filler and other materials are added, the evaporation rate of solvent is greatly reduced. The finer the pigment particles and the larger the surface area, the slower the solvent volatilization.
(4) The influence of environmental temperature and humidity. The higher the room temperature is, the faster the solvent volatilization is, and vice versa. Indoor air circulation, solvent volatilization is fast, if indoor is relatively closed, solvent volatilization is slow. So high speed gravure or flexo press are equipped with heating and exhaust devices. If possible, the plastic printing plant should be equipped with solvent recovery device, which can not only solve the drying problem of solvent volatile ink layer, but also solve the pollution problem, which is beneficial to the physical and mental health of employees.
