With the continuous innovation and advancement of technology and the introduction of new pigments and additives, inks can present more vivid and full colors and achieve some special effects, such as metallic luster, fluorescent effects, etc. The use of defoamer for printing ink further improves the quality and special effects of the ink.
The main function of
defoamer for printing ink is to reduce the surface tension of the ink surface, thereby preventing the formation of bubbles.
1. Disperse bubbles: It can quickly disperse bubbles and evenly distribute them on the ink surface, thereby reducing the impact of bubbles on printed matter.
2. Inhibit bubble formation: It can destroy the membrane structure of bubbles, prevent new bubbles from forming, and effectively control bubble problems.
3. Improve printing quality: It can reduce the impact of bubbles on the surface of printed matter, make the color of printed matter more uniform and clear, and reduce flaws and defects.
How to use of defoamer for printing ink？
1. Select the appropriate type of defoamer for printing ink: Select the appropriate defoamer according to the type and specific requirements of the printing ink.Defoamer are usually available in liquid and powder forms, choose the appropriate form according to your needs.
2. Add an appropriate amount of defoamer for printing ink: According to the amount and concentration of printing ink, add an appropriate amount of defoamer. It is usually recommended to conduct a small-scale trial first to determine the appropriate amount of defoamer.
3. Stir and mix evenly: Add the defoaming agent for printing ink evenly into the printing ink, and use stirring or mixing equipment to fully dissolve and disperse the defoaming agent in the ink.
4. Adjust the dosage: According to the actual printing effect, the dosage of defoamer can be gradually adjusted. Pay attention to controlling the concentration of defoamer to avoid deterioration of ink performance caused by excessive use.
