COBB TESTER

 

Applies to determination of surface water absorption about all kinds of paper or cardboard. But it is not for

 the accurate evaluation of paper or the writing performance of cardboard.

 

Main feature:

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 /m2meter. 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.

 

Technical parameters:

1. The inner crossing section of metal cylinder is 100±0.2 cm2(corresponding to innerdiameter is 

112.8± 0.2mm), cylinder height is 50mm, the contact part between cylindrical ring surface and 

the sample should be smooth.

2. Absorbent paper ration is 200~250g/m2, the absorption rate is 75mm/10min. When the absorbent

paper monolayer quantitatively less than 200 ~ 250 g/m2, can meet the requirements by multilayer stack.

3. Smooth metal flat roll: the length of the roller is 200 ± 0.5mm, the quality should be 10 ± 0.5kg.

4. Test water consumption: 100 mm ± 5 ml.

5. Size and weight: size: < 480 x 400 x 420 (mm), weight: 20kg
