YINUO YN-CBY100 Cobb water-absorption Tester

use

Paper and cardboard absorbency Tester is a conventional instrument for the water absorption test of paper and cardboard surface, also known as paper surface absorption gravimeter. This instrument uses the Cobb test method, which is one of the many methods of absorption testing, so it is also called the erection Tester.

This instrument is mainly used to determine the surface water absorption of sizing paper and cardboard, including corrugated cardboard. This instrument only measures the water absorption of paper and cardboard surfaces, but is not suitable for accurately evaluating the writing properties of paper or cardboard.

Definition of surface water absorption (Cobb) value of paper and cardboard: the amount of water absorbed by the surface of paper and cardboard per unit area under a certain pressure and temperature within a specified time, measured in g/㎡. The specific formula is as follows: C=(G2-G1)×100.

where: C - the value of water absorption;

G2 —— The mass of the specimen weighed after water absorption;

G1 —— The quality of the specimen weighed before water absorption.
