Conjunctiva offset printing ink drying test method
1 Scope
GB/T 14624 provisions of this part of the conjunctiva offset printing ink drying test.
This section applies to the conjunctiva offset printing ink drying test.
Method 2 a
2.1 Principle
Under specified conditions, the surface of a thin layer of ink was measured by the slurry into a solid shortest time, to represent the h.
2.2 tools and materials
2.2.1 Standard sample preparation Paper. 60g/m2 parchment (also known as parchment paper or parchment paper), size 295mm × 210mm, paper inscribed with long
250mm wide and 5mm elongated holes.
2.2.2 Cotton.
2.2.3 scrubbing solvent. ethanol.
2.2.4 palette knife.
2.2.5 blade.
2.2.6 glass.
2.2.7 pins.
2.2.8 timer.
2.3 Test conditions
Test should be carried out at a temperature of (23 ± 2) ℃, relative humidity (65 ± 5)% condition.
2.4 test step
2.4.1 with a palette knife to take a sample of the ink to about 5g, placed on a glass plate to mobilize 15 times (round trip).
2.4.2 has been previously cut holes in parchment good flat coated on a glass plate, two fixed with transparent tape, with palette knife has been thoroughly taken samples
Ink about 2g placed over parchment with equal force to the blade of the ink from the top down through the hole to scrape the bottom.
2.4.3 Peel off parchment-like scratch, leaving a thin layer of parchment ink sample thickness on a glass plate, recording the name, start timing.
2.4.4 Timing with the bulk ink for thin scratches were observed whether collapse within 5min scratches. Such as scratches within the prescribed time is no longer closed,
Compared with the end of the test.
2.5 Test Results
Calculation scraping ink-like finish to scratch no longer closed time (h), compared to a solid surface of a thin layer of ink shortest time (h), namely by
Try conjunctiva ink dry time (h).
3 Method Two
Conjunctiva offset printing ink drying method of automatic test equipment in accordance with Appendix A to operate.
