Since the aqueous ink is a soap composition, bubbles are easily generated during use, so silicone oil is added as a defoaming agent to suppress and eliminate bubbles while improving the ink transfer performance. The retarder is used to suppress the drying speed of the aqueous ink, prevent the ink from drying on the anilox roll, and reduce the paste. Stabilizers can adjust the pH of the ink, and can also be used as a diluent to reduce the viscosity of the ink.
Therefore, I think the heater plays an important role in graphic production. However, some problems have also been presented during the practice test. For example, the problem of the copper plate of the printer is not well controlled, and it is not easy to dry, simple to fade, slow, the adhesion of the ink is not strong, and some papers are printed with ink. So is there a better way to deal with these problems now? The answer is yes.
Imitation printing ink is also weakly soluble ink, so many people are worried that this ink is corrosive, so it is daunting to him. Yes, since it is dissolved in ink, the corrosiveness is inevitable, but the pH of this ink is not very high, weak base, and some taste. In fact, we use the general ink does not rule out the damage to the machine nozzle. If the quality of the ink is not good, it will damage the nozzle. I used a company's pigment ink to break the nozzle. So the question is how to look at this problem, if we are getting a good reward, it is still possible to dedicate something.
In the above aspects of the cause and handling of the encrusted ink, in actual work, we may encounter such problems or problems, but we should not understand the reason of the ink crust (mainly the drying principle). It is very difficult to analyze and judge the high.
