MODERNER ISO-4 ISO Flow Cup inks Viscosity Cup

ISO-4

ISO Flow Cup

Viscosity range 35~ 135cSt, outflow time 30~100s, flow hole diameter 4mm, cup body material anodic oxidation aluminum, filter material brass, applicable to standard ISO 2431.

The ISO outFlow Cup is used to determine the outflow time of paints with Newtonian or near-Newtonian fluids. The range of kinematic viscosity suitable for testing samples is 7-685mm2/s. The ISO outFlow Cup conforms to the national standard GB/T6753.4 Paint and varnish Use the outFlow Cup to measure the outflow time.

Test Range

In the formula: v——kinematic viscosity mm2/s

t——Outflow time s (measured value should be within 30~100s)

preliminary test

1. Choose a certain label outFlow Cup, so that the sample outflow time in the cup is within 30-100s.

2. Before each measurement, wipe the outFlow Cup with a silk cloth dipped in solvent and dry it. The leak nozzle should be clean when observing the light.

3. Adjust the level screw to make the end surface of the outFlow Cup level. in no airflow.

Use and maintenance

1. Place a container under the outFlow Cup, block the outflow hole with your hands, and slowly fill the outFlow Cup with the sample to avoid air bubbles. When the sample is filled with a convex surface and begins to overflow, use a straight-edged scraper or a flat glass plate to slide and push it along the upper edge to scrape off air bubbles and excess samples. Release the finger to allow the sample to flow, that is, start the stopwatch, and stop the stopwatch when the sample flow is interrupted for the first time. The total time that the sample flows out of the outFlow Cup is the outflow time of the sample. The difference between the two measured values should be less than 4% of the average value.

2. If the calibrated cup is used as a standard cup, it should be multiplied by a correction factor (k) value to correct the outflow time deviation.

3. The temperature of the sample is 25°C±0.5°C during the measurement, and it should be measured in a constant temperature room. If the test is not carried out in a constant temperature room, a thermometer should be placed in the sample stream, and the temperature shown should be kept the same as the temperature before the outflow. more than 0.5°C.

4. After the test, the outFlow Cup should be wiped clean with solvent and coated with anti-rust oil. Do not use any sharp and hard metal objects when wiping to prevent scratching the surface.
