Guide for operating a Klemm Capillary Rise Tester
Klemm Capillary Rise Tester is suitable for measuring the capillary liquid absorption height of unglued paper and paperboard.
Klemm Capillary Rise Tester is composed of a base, a pillar, a crossbeam, a horizontal plate, a ruler, a handle, and a water tank. Turning the handle activates the eccentric mechanism to drive the crossbeam to smoothly raise or lower the horizontal plate and ruler.
Guide for operating a Klemm Capillary Rise Tester
1. Rotate the eccentric handle to lower the scale to the lowest position.
2. Inject an appropriate amount of water into the sink, so that the zero points of all scales come into contact with the water surface, and achieve this by adjusting the support feet.
3. Rotate the handle to raise the scale to its highest position.
4. Place the sample horizontally, draw a straight line perpendicular to the length direction at a distance of 205mm from one end of the sample, and then clamp 10 samples on both sides of the ruler on the horizontal plate. The drawn horizontal line should be aligned with the 200mm ruler line.
5. Rotate the eccentric handle to lower the scale to the lowest position. At this point, the zero point of each scale is just in contact with the water surface, while the sample is 5mm deep in the water. Press the stopwatch to time, and then determine the required time or value of the capillary suction height of the sample within a certain period of time. Generally, the suction height within 10 minutes ± 3 seconds is used, expressed in s/mm or mm/s.
6. Accurate to 1mm when reading numbers. If the suction wetting line is tilted or bent, the results should be read according to the average height.
7. The length of the sample deep into the liquid can be appropriately extended according to product standards or other requirements, but it should be noted in the test report.
