Setting of ink viscosity used by Polyester Printing mesh

Polyester screen printing mesh is often used in manufacturers of various industries. Eighty percent of the printing in China's factories requires maishi's printing mesh. The maishi manufacturer with rich production experience tells us the setting of ink viscosity in the following printing meshs.

The first thing we need to understand is what are the factors that affect the viscosity of the ink?

1. The dissolved viscosity of the ink's own link resin. That is, the smaller the viscosity of the solution of a certain amount of the resin and the solvent, the smaller the viscosity of the ink, and vice versa.

2. The compatibility of the pigment and the binder, the pigment and the binder in the ink production do not undergo a coagulation chemical reaction, and here refers to whether the ink is thickened after the ink is produced. Small method: take the ink in the stock, shake the ink bucket to hear the sound, loud sound of the ink is good, because the ink is stored for a period of time, there may be thickening phenomenon. The miscibility and compatibility of the solvent and the dispersion.

If the viscosity of the ink is not suitable, it will cause any kind of problem.

The size of the viscosity causes poor ink flow and poor ink circulation on the screen plate. The finished product will have anti-sticking which is difficult to dry in the paste and orange peel printing. It is discolored in the next process. It will cause problems such as dyeing the adhesive.
