Cobb sizing tester determines the amount of water or any liquid absorbed by the paper, corrugated fiberboard, and paperboard in a given period of time under some conditions.
Purpose And Standard Operating Procedure Of Cobb Sizing Tester
Cobb sizing tester determines the amount of water or any liquid absorbed by the paper, corrugated fiberboard, and paperboard in a given period of time under some conditions. Water absorptiveness is a function of various characteristics of paper or board such as porosity, sizing, etc. The high Cobb value of the papers and cardboards indicates the ability of the materials to retain or absorb the moisture. Depending upon the application of the board, the Cobb value needs to be maintained.
