Introduction
The use of the borgle method to determine the surface water absorption capacity of paper and cardboard (erection value), is suitable for measuring the water absorption of the surface of sizing paper and cardboard, not suitable for base paper and embossed paper with a quantitative amount of less than 50g/m², low sizing degree or more pinholes, not suitable for unsizing paper and cardboard, and not suitable for accurately evaluating the writing performance of paper and cardboard.
peculiarity
1. Adopt flip structure
2. It comes with a stopwatch, with a reminder of removing the remaining water and completing the water absorption time
3. The test time can be selected, and the standard test time is 30s, 60s, 120s, and 360s
4. Flip and absorb water and start timing at the same time
