Paper Water Absorbency Tester

Test area (100 +/- 0.2) cm ², test water consumption 100ml, roller length 200 +/- 0.5mm, roller mass 10 +/- 0.5kg

The test area is 100cm ², the height of the cylinder is 50mm, and the mass of the pressing roller is 10kg. The water absorption on the paper surface is accurately determined by the Cobb test method.

It is suitable for measuring the water-absorption of various paper or Cardboard surfaces, with a test area of (100 +/- 0.2) cm ², the weight of absorbent paper is 200~250g/m ², and the absorption speed is 75mm/min.

Complies with ISO 535-1991 and GB/T1540-2002 standards. The instrument provides accurate water-absorption energy data by measuring the mass increase of the liquid absorbed by the paper. It is compact and equipped with a 200mm press roller, with quality control in the range of 10 +/- 0.5kg

The inner cross-sectional area of the metal cylinder is 100 +/- 0.2cm2, the weight of absorbent paper is 200~250g/㎡, which conforms to the GB/T1540 standard, and the test water consumption is 100mm +/- 5ml.

Paper and Cardboard surface water-absorption test of conventional equipment, test area (100 +/- 0.2) cm ², test area (122.718 +/- 0.2) cm ², liquid height 10mm, test water consumption 100ml +/- 5ml, roller length 200 +/- 0.5mm, roller mass 10 +/- 0.5kg.

The Cobb (Cobb) test method can accurately measure the water weight absorbed by the paper surface within the specified time, which is suitable for the quality control and mass inspection of various paper and Cardboard, with high accuracy and reliability, and provides important test data for the paper industry.
