LIYI Digital ISO535 Cobb Moisture Absorption Tester For Cardboard And Paper Product Description
Paper COBB Absorption Tester is mainly used for determination of sized paper and cardboard including surface water imbibition of the corrugated cardboard. The instrument is determination of absorbent paper and cardboard surface, but is not suitable for accurate evaluation of paper or paperboard writing performance.
The Cobb test determines the amount of water absorbed into the surface by a sized (non-bibulous) paper, paperboard, and corrugated fibreboard paper or paperboard sample in a set period of time, usually 60 or 180 seconds (Cobb60 or Cobb180). Water absorbency is quoted in g/m2. The water absorbency of a material can have strong influence on printability and the setting rate of water based adhesives. Test Standard: ISO535—1991,GB/T1540—1989 and so on. Specification
