Ethyl Cellulose K70 K100 for Magnetic ink

Magnetic ink preparationedit
There are many ways to prepare magnetic ink. The magnetic ink used for jet printing is to add a humectant and surfactant to the magnetic particles replaced by unsaturated viscosity. The former makes the particles easier to suspend in water and reduces the interfacial tension between the particles. In the case of this water-based magnetizing liquid, the surfactant can be cationic, anionic or nonionic as appropriate. On the basis, in order to improve the stability of the magnetic ink, it is necessary to add polyethylene glycol.
In order to convert into filterable ink, it is necessary to add glycerol. Adding glycerol eliminates the change in the magnetic moment of the ink due to evaporation loss when the magnetic ink is repeatedly circulated. At the same time, it prevents the ink from peeling or clogging the nozzle due to drying too fast. . Furthermore, in order to increase the absorption of ink on paper, ethylene butyl butyl ether is added. In order to meet the requirements of magnetic recording and magnetic printing, its magnetization, viscosity, stability, jet orientation, evaporation speed and from the point of view of printing quality, due to the iron oxide in the magnetic ink droplets, it has magnetism. Is a kind of storage printing
