Many printing plants in the printing process, due to a lot of equipment and environmental problems, so the indoor temperature will be relatively high, which will lead to the phenomenon of ink peeling, the following will give you an analysis of the reasons for the high temperature of ink peeling:
First, the temperature of ink crust is too high, which mainly causes high temperature. When the ink temperature is too high, the activity of unsaturated molecules increases, especially the oxygen in the oxidation between surface air and conjunctiva.
2. Several aspects of high temperature:
1. Other abnormal temperature rise of the machine.
2. Air leaks from the dryer to dry the ink surface, or hot air enters the ink bucket.
3. The ambient temperature is too high: In general, the phenomenon of ink peeling in summer is much more obvious than in winter. If there is no air conditioning in the workshop, the performance is more obvious. It is necessary to control the temperature of working environment reasonably.
4. When the temperature on the machine is too high, it will also make the ink in the printing process:
(1) When the contact pressure between ink rollers is too high, the temperature rise is more significant. At this time, ink can easily appear in the phenomenon of peeling between ink rollers and ink rollers.
(2) It is of great significance to accurately regulate and control the pressure between ink rollers in order to prevent the influence of ink in the printing process.
(3) Generally speaking, the workshop temperature control is ideal at about 20 C, that is, to ensure good fluidity and transfer performance of ink, while the ink crust control is at a relatively low level.
3. Excessive dry oil content in ink:
Such errors usually occur in the process of making ink or printing. When adding desiccant, it must be combined with printing conditions and ambient temperature for proper addition.
In printing, there are many factors leading to ink peeling, and high temperature is one of the common factors, so in future printing, our staff should reasonably control the indoor temperature, maintain room temperature, reduce unnecessary trouble.
