The rapid development of the printing industry has promoted the wide application of ink, which is almost everywhere in human daily life. Whether it is in books, newspapers or advertising materials, we can see the figure of ink.




In the daily work of the printing plant, the use of ink is an indispensable part. However, sometimes we may encounter some problems, such as ink blistering.




This phenomenon usually occurs because certain components of the ink react with gases in the air, resulting in bubbles. These bubbles will affect the quality of the ink, in the use of ink with bubbles printing, so that there are defects in the printed product. How to remove the foam of the ink, you can use ink defoamer to remove.






What causes the ink to blister?


Ink foaming is due to the printing plant in the production and use of ink to add high hardness of tap water, so that the surface tension of the ink solvent is different; The viscosity of the ink is large, and the air is difficult to escape; In order to improve the performance of the ink will add chemical additives, these additives contain surfactants; In addition, in the process of production and use of ink, due to the stirring operation of the equipment, resulting in the involvement of a large amount of air and so on, foam is generated.






What are the effects of the presence of bubbles?
Foam will affect ink printing, resulting in white spots and other defects in printing, affecting the beauty of printing; The fluidity of the ink is poor, resulting in uneven surface of the ink printing, reducing the gloss of the ink; A large number of foams will also slow down the production progress of ink, resulting in the extension of the production cycle and increasing the production cost of ink.






What are the characteristics of ink defoamer?
Ink defoamer is composed of polyether containing special modification through special process, soluble in water, suitable for oil phase foaming system defoamer, product stability is good; Good compatibility with organic hydrocarbons, adding oil system does not affect the transparency of the product, has a certain leveling performance. It can be widely used for foam removal of various harsh systems over a wide temperature range.
