SUMSPRING KBXS-01 Cobb Absorption Tester

Introduction

The KBXS-01 is suitable for measuring the water absorption of various white cardboard, whiteboard paper, containerboard, carton paper, kraft boxing paper and other surfaces, but it is not suitable for accurately evaluating the writing performance of paper or cardboard. It is used in papermaking, packaging and printing manufacturers.

The principle of the test

Water absorption value of paper and cardboard surface (Cobb method): 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-oberection value;

G2 - the mass of the specimen weighed after water absorption;

G1 - The mass of the specimen weighed before water absorption.

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.
