3rd step: prepared sample is tested on electronic stripping tester its T-shaped peel strength；
4th step: size and Failure type according to peel strength value judge that adhesive force is the most qualified.Combine
Closing the two and implement marking to sample, 10 are divided into full marks-adhesive tape more almost ink film all to peel off, and score value is more
High attachment is the best, and 0 is divided into layer of ink large area (> 80%) peel off.
3, viscosity test: GB/T 14624.5-1993.
4, the fluidity method of inspection: GB/T 14624.3-2008.
5, form and aspect test: GB/T 14624.1-2009, contrasts with standard specimen, gives a mark according to difference degree, complete
Entirely being unanimously 10 points, the biggest score value of gap is the lowest.
6, fineness test: QB 559-1983.
7, stability test: ink is carried out certain time (3 days) freezing (-15～-20 DEG C) and
Heating (75～80 DEG C) test, observes whether ink has gel situation or anti-thick phenomenon.Then according to each
Ink situation implements marking (10 score value), and 10 are divided into full marks-almost no change, and 0 is divided into stability extreme difference,
The most seriously can not use.
