Uses:
Paper 500mm Cylinder 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 notsuitable for accurate evaluation of paper or paperboard writing performance.
Features:
The value of paper and cardboard surface water absorbing capacity (Cobb): the unit area of paper and cardboard in a certain pressure and temperature, within the time specified the absorption of water by surface to g /m2 meter. The specific formula is as follows: C = (G2 - G1) x 100. (C - value of Cobb water absorption; G2 - the sample quality after absorbing water; G1 - the sample quality before absorbing water) Paper and cardboard absorbing tester is the conventional instrument of the paper and cardboard surface water absorption test, also called the weight of paper surface absorption tester. The instrument adopts Cobb test method of the various methods in the absorption test, it is also called Cobb absorption tester.
