Winter ink preservation deployment knowledge

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 allocate ink to the area, the total amount of various additives that the original ink produced by the ink manufacturer can hold is limited. Exceeding the limit amount, even if it can be used, it also weakens the basic performance of the ink. Affect print quality. In addition to excessive packaging, the viscosity and consistency of the ink are related. Here it refers to its nature rather than 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, unemployment and thick inks are not necessarily highly viscous, and inks with high viscosity are not always very thick.

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 heating, and let it slowly warm up to its original state.

(2) External heating can be performed by 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 the water vapor from immersing until the water temperature drops to 27 Remove it when it is about °C, and open the lid and stir it to use. The temperature of the printing shop is preferably kept at about 27°C.

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 Shanghai Electric, it can be summarized as the following two reasons: First, caused by the strong thixotropy of the original structure of the original ink, but after stirring to restore the original state can still be used; second is expired Ink or spoiled ink resulting from improper storage cannot be used.

Place the original ink on the radiator or beside the radiator so that it slowly warms up and gradually returns to its original shape. Emergency use of boiling water for external heating, the specific method is to pour boiling water into the basin, the Donnelly, and then the original barrel (box) ink in the water, but to prevent the water vapor immersed until the water temperature dropped to around 27 °C Take it out, open the lid and stir it to use. The temperature of the printing shop is preferably kept at about 27°C. The solution must be remembered!
