Test area of 100cm ², cylinder height of 50mm, can accurately determine the unit area of paper and Cardboard in the specified time surface absorption of water, using the Cobb test method for surface Water Absorbency test.
The Water Absorbency of paper surface was measured by Cobb test method, the test area was 100cm ², the cylinder height was 50mm, the absorbent paper Basis Weight was 200~ 250g/m2, and the pressure roller mass was 10kg to ensure the accuracy of the test.
The surface water absorption of paper and Cardboard was measured by Cobb test method, the test area was 100 +/- 0.2cm ², and the mass of the pressing roller was 10 +/- 0.5kg. The water absorption value of Cobb can be accurately calculated.
The Cobb test method is used to determine the water absorption value per unit area, the test area is 100cm ², the cylinder height is 50mm, and it is equipped with Basis Weight 200-250g/m2 absorbent paper, which meets the requirements of ISO535 and GB/T1540 standards.
The ink wiping speed is 15.5cm/min, the opening area of the ink coating platen is 20cm ², and the ink absorption time is 120s. The test process is automatically controlled to accurately determine the absorption capacity and penetration performance of the paper to inks.
The Cobb test method was used to measure the water absorption per unit area, the cross-sectional area of the cylinder was 100 +/- 0.2cm ², and the Basis Weight of the absorbent paper was 200~ 250g/m2, which was suitable for the determination of the surface absorption weight of paper and Cardboard.
The ink wiping speed is 15.5 +/- 1.0cm/min, the opening area of the ink coating platen is 20 +/- 0.4cm ², and the ink absorption time is 120 +/- 5s. It is controlled by 4.3 inch color Touchscreen, which is suitable for the absorption performance measurement of paper inks.
Using the Cobb test method, the test area is 100cm ² +/- 0.2, and the pressure roller mass is 10kg +/- 0.5, which is suitable for the detection of Water Absorbency on the surface of sizing paper and Cardboard, and is not suitable for loose or unsizing paper.
The test area is 100cm ² and the press roller mass is 10kg, which can accurately determine the Water Absorbency of the paper surface, and is suitable for the quality control and detection and analysis of the adhesive paper.
The instrument can simultaneously measure 10 samples, equipped with 5 Graduation 1mm engraving rulers, suitable for the detection of unglued paper with a capillary liquid absorption height of more than 5mm.
Measurement range is 5-200mm Graduation 1mm, and smooth operation is realized by eccentric lifting mechanism, which is suitable for capillary liquid absorption height measurement.
Using 100cm ² standard test area and 100ml test water, equipped with 10kg pressure roller to ensure uniform pressure of the sample, can accurately measure the liquid absorption in different time periods from 30s to 1800s, to meet a variety of test needs.
Measurement range 0-200mm, using Krem design principle, suitable for capillary liquid absorption height determination, Graduation accuracy to 1mm.
