As an important material for printing, ink is composed of resin, pigment, filler and auxiliary. Due to many industries such as books, packaging, construction, and circuit boards, with the gradual increase in social demand, the use of ink is also increasing. However, in the production and use of ink, due to the addition of surfactants, equipment stirring operation and environmental changes will cause ink foam problems, these foams will not only reduce the efficiency of ink production, but also affect the performance and quality of ink, which has become a problem for many ink manufacturers.

What causes the ink to blister?

1.High hardness tap water is added in the production and use of ink, so that the surface tension of the ink solvent is different;

2.The viscosity of the ink is large, the air is difficult to escape, and the foam will be formed inside;

3.In order to improve the performance of the ink will add chemical additives, these additives contain surfactants, it is easy to lead to ink foaming;

4.In the production and use of ink due to the stirring operation of the equipment, resulting in the involvement of a large amount of air, resulting in foam

What harm will there be if the foam of the ink is not eliminated in time?

1.Foaming will affect ink printing, resulting in defects such as white spots during printing, affecting the aesthetics of printing;

2.Foam can also lead to poor ink fluidity, resulting in uneven ink printing surface, reduce the gloss of the ink;

3.Lead to the pigment and filler can not be fused, so that the sizing is not uniform;

4.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.

Therefore, in order to improve the quality of ink, reduce the defects of ink foaming, restore the normal ink production schedule, and avoid unnecessary costs, the use of ink defoamer is a good choice. The defoamer has fast defoaming speed and long defoaming time. In the high temperature, strong acid, strong alkali environment can also play its stable anti-foam and anti-foam performance; Adding to the ink will not affect the basic system of the ink, will not affect the performance of the ink, will not change the appearance and color of the ink; Good water solubility, good dispersion, can quickly penetrate the inside of the ink, no oil, no precipitation.
