Automatic Paper Board Surface Intbuying Cobb Water Absorption Tester
Application:
Paper and paper absorbency testers are conventional instruments for the water absorption test of paper and paperboard, also known as paper surface absorption weight gauges.
Standards:
This instrument is designed according to the basic parameters and requirements specified in ISO 535 paper and paperboard - water absorption measurement (Bob method), GB/T1540-2002 paper and paperboard water absorption measurement method. This standard is suitable for determining the water absorption of various paper or board surfaces. It does not apply to the accurate evaluation of the writing performance of paper or cardboard.
Specifications:
1. The cross-sectional area of the metal cylinder is 100±0.2cm2 (the corresponding inner diameter is 112.8±0.2mm).
Cylinder height: 50mm, the contact surface of the cylinder to the sample should be smooth.
2. When the basis weight of the absorbent paper is 200 to 250 g/m 2,the absorption speed is 75 mm/10 min.
When the basis weight of the absorbent paper is less than 200 to 250 g/m2, multiple layers can be used to meet the requirements.
3. Smooth metal flat roll:
The width of the roller is 200±0.5mm,
The mass should be 10 ± 0.5kg.
4. Test water consumption: 100ml ± 5ml
5. Instrument net weight: 28kg
