Description
Summary:
The design of the instrument is based on the GB/T1540- 2002 paper and cardboard water
Absorption method (Cobb method) provide basic parameters and requirements. This standard
Applies to determination of surface water absorption about all kids of paper or cardboard. But it is
not for the accurate evaluation of paper or the writing performance of cardboard.
Main 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.
