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
Name: Ethyl Cellulose
In the formula , n stands for degree of polymerization and R for –H or –C2H5 .
Ethyl Cellulose is a kind of white grains or powder, having no smell or tastes . Its 5% soliquoid shows neutral to litmus test paper . Its specific density 1 . 07~1 . 18 , heat distortion point: 135~155degree centigrade , and fire point: 330~360 degree centigrade . Ethyl Cellulose has good stability to light , heat , oxygen and wetness , and is stable to chemicals . It is resistant to alcali , dilute acid and salting liquid , soluble in some organic solvents , such as alcohol , ether, ketone , ester, aromatic hydrocarbon and halohydrocarbon , etc , and compatible to many celluloses , resin and nearly all plasticizers . Ethyl Cellulose has low combustibility, small hydroscopicity and good electric behavior . Its thin film and plastics have good mechanical strength and flexibility in a wide range of temperature .
