Overview
The paper water absorption tester JW-113 is a JINGWEN brand product, which is mainly used to measure the mass of water or Miscellaneous liquid absorbed by the surface of sizing paper and Cardboard including Corrugated Board. It is suitable for the penetration of water or Miscellaneous liquid on the surface of the paper. When measuring, one side of the paper is first contacted with the liquid. After a certain period of time, the increased mass (g/m2) can be measured.
Features
The logarithmic structure and technical performance of the instrument meet the requirements of GB/T 1540-2002 "Paper and Cardboard Water Absorbency Determination Method" (Cobb Method) and other relevant standards.
The test area is accurate to (100 +/- 0.2) cm ².
3. The test water consumption was fixed at 100 ml.
4. The length of the pressing roller is 200 +/- 0.5mm, and the mass of the pressing roller is 10 +/- 0.5kg.
5. Dimension is 420 * 320 * 400mm, Net weight is about 28kg.
Principle
The instrument evaluates the Water Absorbency of paper by contacting one side of the paper with the liquid and measuring the increased mass (g/m2) of the paper surface after absorbing water or Miscellaneous liquid after a certain period of time.
Applications
Adhesive Paper, Cardboard, Corrugated Board
Standards
ISO535—1991、GB/T1540—1989
Steps
1. Prepare paper samples.
2. Contact one side of the paper with the liquid.
3. After a certain period of time, the measurement of the increased mass (g/m2).
Notice
• Ensure that the test area is (100 +/- 0.2) cm ².
• The test water consumption should be accurate to 100ml.
• Roller length and mass must meet specifications: 200 +/- 0.5mm and 10 +/- 0.5kg.
• Dimensions and weight of the instrument during operation to avoid improper handling.
