How to solve the thickening problem of winter ink

Low winter temperatures are external factors that make the ink thicker. Under the influence of temperature, the thick change of the ink (primary ink) is a physical phenomenon, but the change is the morphology, not the essence (the basic performance of the ink).

The ink is too thick and the viscosity is large, but it is best not to use thinner or varnish to adjust its consistency. Because when the user needs to mix the ink, the total amount of various additives that the original ink produced by the ink manufacturer can accommodate is limited, beyond the limit amount, even if it can be used, it also weakens the basic performance of the ink, affecting the printing Quality printing technology. In addition, the viscosity and the consistency of the ink are related. Here it refers to its properties and not to its phenomenon. In practice, this is often the case. The ink has a large consistency, but its viscosity is small and its fluidity is still large. Therefore, inks with large consistency do not necessarily have high viscosity, and inks with large viscosity do not necessarily have large consistency.

The thickening phenomenon of ink caused by temperature can be solved by the following methods:

(1) Put the original ink on the radiator or beside the radiator so that the temperature will gradually increase to its original state;

(2) External heating can be performed using boiling water in emergencies. The specific method is to pour boiling water into the basin, and then put the original barrel (box) ink in the water, but to prevent water vapor from immersing until the water temperature drops to around 27 degrees Celsius. Remove it, open the lid and stir it to use. The temperature of the printing shop is preferably kept at around 27 degrees Celsius.

The ink is also thick at normal temperatures because the consistency of the ink reflects the rheological properties of the ink to some extent. If it is not due to external factors caused by the phenomenon of thickening, can be summarized as the following two reasons: First, due to the strong thixotropy in the original structure of the ink caused by, but after stirring to restore the original state, can still be used; two expired ink or Deterioration inks due to improper storage cannot be used.
