Canadian Freeness Tester CSF-20
Measures the rate of drainage of a diluted pulp suspension. The drainage rate is related to the surface conditions and swelling of the fibers. It is widely used to track the changes in the drainage rate of various chemical pulps during beating and refining.
The values obtained in the Freeness Tester CSF-20 Canadian method (ºCSF or ml) are the measure to which a pulp suspension performs dewatering.
Based on the TAPPI T227 and ISO 5267/2 standards, 3 dry grams of paper pulp are diluted in water and the suspension is poured into the drain container.The upper lid closes, and the lower lid opens.The suspension is now on the calibrated sieve plate.
