The paper water absorption meter is designed and manufactured according to the technical specifications and technical requirements stipulated in QB/T1662 Klemm Absorber. The paper water absorption tester is suitable for the measurement of the capillary aspiration height of unsized paper and paperboard. (Not applicable to paper and cardboard with a capillary suction height less than 5 mm in 10 min). The following is the specific operation method of the paper water absorption rate detector .
Paper Water Absorption Tester Procedure
1. Turn the eccentric handle to lower the ruler to a lower position.
2. Inject a proper amount of water into the water tank so that the zero point of all the rulers touch the water surface and adjust the foot.
3. Turn the handle to raise the ruler to a higher position.
4. Lay the sample flat, draw a line perpendicular to the length direction at 205 mm from the end of the sample, and then
Ten specimens are clamped on both sides of the ruler on the transverse plate, and the horizontal line should be aligned with the 200 mm ruled line.
5. Rotate the eccentric handle to lower the ruler to the lower position. At this time, the zero point of each ruler just touches the water surface, and the sample is 5mm deep into the water. Press the stopwatch to count the time, so as to determine the required height of the sample capillary suction. The height of the sample capillary aspiration during the time or within a certain period of time. Generally, the aspiration height within 10 min ± 3 s is expressed in s/mm or mm/s.
6. Accurate to 1mm when reading numbers. If the pipetting line is inclined or bent, the result should be read at the average height.
7. The length of the sample in the liquid can be extended according to product standards or other requirements, but it should be noted in the test report.
