? ? ? ? ? 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.
