Phenomenon: The static electricity generated by the packaging and printing substrates is not easy to print. For example, it is difficult to overprint, misalign, and the electric shock generated by the packaging printing ink is not easy to ink, rewind, cut and package.
Reasons: 1 is that the packaging substrate is not anti-static or conductive; 2 is the difference in the absorption of molecules, atoms and ground electrons of different substances in the printing ink system. When the substrate is contacted, two different substances are When the surfaces touch each other, an electric charge can be generated instantaneously, and a small amount of static charge is sufficient to form a very high static voltage. For this reason, even electrical layers are used to form extremely high electrostatic voltages. To this end, the electrostatic layer is used to explain electrostatic discharge (electrostatic printing) to the charged object. It is generally believed that the positive and negative charges in the atom in equilibrium are due to the surface energy received in the ink and printing contact friction, and thus the even layer is formed. When you get rid of friction, you lose the positive charge on one side of the electron, and the negative charge on the side on which the electron is obtained, and you end up charging the print job. Our general explanation is that molecules containing more polar groups in the molecule tend to carry positive charges, while non-polar polymers tend to carry charges. In short: the accumulation of static charges is the source of electrostatic faults. .
Method: 1 Add 3500 antistatic agent, can also add conductive agent 1220, generally controlled in (2.0% of antistatic agent) between 1.2% and 2.5%, and 30% of 1220 dispersant, also affect the adhesion of ink Fastness.
