(Summary description)1.Interfacial tension:
Take mN/m as the unit. Unlike the so-called "surface tension", the interfacial tension includes the surrounding medium, for example, air is mostly used as the medium during testing. This parameter affects the following performance?
a. How sharp is the edge of the printed font?
b. Ink permeability in paper and other media?
The range of common ink interfacial tension values for ink fluidity in ink cartridges:? Epson and Canon black and color inks <34 mN/m @ 20C, HP and Lexmark black inks> 50 mN/m @ 20°C,? HP and Lexmark Color ink <34 mN/m @ 20°C.
Use low interfacial tension ink: small ink droplets, the ink will penetrate deeper into paper or other media. Use high interfacial tension ink: large ink droplets, less permeability to the medium. However, too high interfacial tension will cause a lot of foam , This ink is not up to standard.
2 Viscosity:
Viscosity will affect the following properties of the ink:
a. The edge sharpness of printed fonts and ink permeability in paper and other media
b. The fluidity of the ink in the ink cartridges (especially the ink cartridges with sponge, such as HP color ink cartridges and Lexmark black/color ink cartridges)
c. The ink flow is blocked (if the ink viscosity is too high, the ink flow will be completely blocked).
3. pH value
a. If the pH value is too low (acidic), the ink will corrode the ink cartridge
b. If the pH value is too high (alkaline), additional salt will be produced, which will reduce the service life of the cartridge (corrosion) and increase the conductivity
c. To ensure good stability of the ink, the pH value of the ink must be equivalent to the pH value required by the dye
4. Conductivity:
In the ink, the conductivity value is used to reflect the level of salt content. This parameter is affected by the following factors:
a. The salt in the water/ink (such as sodium chloride) will damage the ink cartridge or even make the ink cartridge useless.
b. The ionic nature of the dye will not damage the ink cartridge like salt.
Generally speaking, the salt content should not exceed 0.5%, and the conductivity should be less than 10000us/cm; to avoid the formation of crystals in the nozzle. To
5. Density and particle size:
This parameter is affected by the composition of the ink.
a. The density of dye-based inks is mostly between 1.00 and 1.03
b. The density of pigment ink is approximately 1.04. The particle size of the ink should be less than 0.2um.
