The testing method explanation
IR spectroscopy: use Fourier transformation infrared spectrometer that dispersion agent is tested, resolution setting is 4cm
-1, scanning times is set at 16.
Jetting stability is estimated: use Epson Stylus Pro 7910 stamping machines that ink to be measured is carried out continous inkjet output; After 5 square metres of continuous outputs; The inspection condition of nozzles; The intact not broken string of nozzle is recorded as good, and there have 1 to 5 nozzle broken string to be recorded as to be poor, has more than 5 nozzle broken strings to be recorded as extreme difference.
Interrupted injection estimation of stability: use Epson Stylus Pro 7910 stamping machines that ink to be measured is carried out continous inkjet output; After 5 square metres of continuous outputs; Left standstill stamping machine 12 hours, and checked condition of nozzles afterwards, the intact not broken string of nozzle is recorded as good; There have 1 to 5 nozzle broken string to be recorded as to be poor, has more than 5 nozzle broken strings to be recorded as extreme difference.
Dispersion stabilization is estimated: at first use dynamic laser scattering particle size analyzer to measure the granularity of ink, it is initial to be labeled as D50/; Then ink sealing to be measured is placed in the incubator of 60 ℃ of constant temperature, two weeks back taking-up ink to be measured still uses dynamic laser scattering particle size analyzer to measure the granularity of ink once more, is labeled as D50/2 after week; If changing, the granularity difference of twice measurement is recorded as well less than 10 nanometers, medium if the variation of the granularity difference of twice measurement is recorded as less than 30 nanometers greater than 10 nanometers, and poor if the variation of the granularity difference of twice measurement is recorded as greater than 30 nanometers.
