Paper Cobb absorption tester

  1. Metal cylinder cross-sectional area of Paper Cobb absorption tester of 100 ± 0.2 cm (corresponding to an internal diameter of 112.8 ± 0.2mm), the cylinder height of 50mm,
    the contact surface of the cylindrical torus and the sample should be smooth. 2 absorbent paper quantitative 200 ~ 250g / ㎡, the absorption rate of 75mm / 10min. When the absorbent paper monolayer quantitative less than 200 ~ 250 g / ㎡, you can use multi-layer stack to
    meet the requirements.
  2. Smooth metal flat roller: the length of the roller
    200 ± 0.5mm, the mass should be 10 ± 0.5kg.
  3. Test water consumption: 100mm ± 5ml.
  4. Weight: 28kg
