Overview

Cobb absorbency tester is a special instrument designed according to the basic parameters and requirements specified in GB/T1540-2002 Paper and Cardboard Water Absorbency Determination Method (Cobb Method). The instrument is mainly used to measure the water absorption on the surface of sizing paper and Cardboard under standard conditions. The water absorption value of Cobb is calculated by measuring the water absorbed by the surface of the area paper and Cardboard within a specified time under a certain pressure and temperature. The calculation formula is C = (G2-G1) × 100, where C is the water absorption value of Cobb, G2 is the sample mass after water absorption, and G1 is the sample mass before water absorption.

Features

1. Comply with the basic parameters and requirements specified in the GB/T 1540-2002 standard 2. Using the Cobb (Cobb) test method for determination 3. The test area is precisely controlled within (100 +/- 0.2) cm ² 4. Precise control of roller mass at 10 +/- 0.5kg 5. The test water consumption is precisely controlled at 100 +/- 5ml

Principle

The instrument uses the Cobb test method to calculate the surface Water Absorbency by measuring the mass change of the paper or Cardboard sample before and after water absorption under standard conditions. Place the sample in a cylinder with a specified area, add quantitative test water, and weigh the sample mass after absorption within a specified time. According to the formula C = (G2-G1) × 100, the Cobb water absorption value is calculated, and the Water Absorbency on the surface of the paper or Cardboard is expressed in g/m2.

Applications

Determination of Surface Water Absorbency on Sizing Paper and Cardboard

Standards

GB/T1540-2002

Steps

Prepare the sample and weigh the mass G1 before absorption 2. Place the specimen in the test cylinder 3. Add 100 +/- 5ml of test water 4. Conduct the water absorption test within the specified time 5. Take out the sample and weigh the absorbed mass G2 6. Calculate the water absorption value of Cobb according to the formula C = (G2-G1) × 100
