1. Principle a certain volume of ink sample under the specified pressure, after a certain period of time, the diameter of the cylinder expanded, expressed in mm. 2. Tools and materials: (1) taper steel body with wood handle of ink mixing knife, 200 mm long, 20 mm wide and 8 mm narrow; (2) glass plate 200 mm × 200 mm × 5 mm; (3) ethanol industry; (4) cotton yarn. 3. Instrument (1) fluidity tester consists of a fifth class weight with a mass of (200 ± 0.05) g; two pieces of round glass with a mass of (50 ± 0.05) g, a thickness of 5-6 mm and a diameter of 65-70 mm; a metal fixed plate; (2) the ink suction tube capacity is 0.1 ml; (3) the graduation value of the transparent measuring ruler is 1 mm; (4) the timing clock. 4. The test condition test should be carried out at the temperature of (25 ± 1) ℃ and relative humidity of 65% ± 5%. 5. Test steps: (1) the ink sample and fluidity tester should be placed in the constant temperature room for 20min in advance; (2) take 2-3g ink sample with ink mixing knife, and transfer it on the glass plate for 15 times (one round trip). Draw 0.1ml of sample with an ink suction tube, scrape off the residual ink at the nozzle and around the tube, so that the sample is flush with the nozzle, and the ink in the tube shall not contain bubbles; (3) extrude the ink in the ink suction tube, scrape the ink into the center of the round glass plate in the metal fixed plate with an ink mixing knife, and scrape off the residual ink from the ink absorption tube core and wipe it on the center of the upper round glass sheet; (4) Place the upper round glass piece on the round glass in the metal fixed plate, so that the ink part in the middle overlaps, press on the weight immediately and start to record the time (pay attention to keep the metal fixed plate horizontal); (5) when 15min, remove the weight, measure the diameter of the ink circle with a transparent measuring ruler, and cross measure twice. 6. The average value of cross measurement is the mobility data. If the cross measurement difference is greater than or equal to 2mm, the test must be repeated.
