The inner section area of the metal cylinder is 100 +/- 0.2cm ², and the test water consumption is 100mm +/- 5ml. It is suitable for the determination of Water Absorbency on the surface of sizing paper and Cardboard. The operation is simple and the results are accurate.
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 equipment adopts white water circulation system, equipped with electric sizing and aeRodynamic bubble homogenizing functions, the diaMeter of the extraction cylinder is 200mm and the capacity is 8 liters. It supports external vacuum suction, and the volume is small and easy to move.
Test area of 100cm ², press roller mass 10kg, can accurately determine the surface of the paper liquid absorption mass, in line with international standards.
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 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 three-point positioning guide structure and pure copper wear-resistant sleeve are used to ensure coaxial concentric accuracy; the service life of the special treatment die blade is up to 10 years; the sampling thickness range is 0.1~ 1.5mm, which meets the needs of various paper testing.
Surface Water Absorbency was measured by Cobb test method, test area 100cm ² accuracy +/- 0.2cm ², liquid height 10mm, pressure roller mass 10kg to ensure uniform pressure, Cup body 316 stainless steel corrosion resistance.
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.
