These Canadian Freeness Tester Are manufactured With High-quality Material. The Canadian Freeness (CF) number of pulp is a measure of the drainability of a suspension of pulp in water, determined and expressed as specified in this method.
A known volume of pulp in aqueous suspension is drained through the fibre mat, formed on a screen plate during the test, into a funnel provided a bottom and a side orifice. The filtrate collected from the side orifice is measured in a cylinder graduated in millimeters, as a Canadian Freeness number of pulp.
Limitation of the Test : This method applies to any kind of pulp with this limitations. The Canadian Freeness test gives acceptable results only if a sufficiently dense mat of fibres is formed on the screen plat. For this reason the test is not recommended for very short-fibred pulps such as those from well beaten hardwood, as most of the fibres may pass through a the screen plate, and high CF number will result although the pulp will drain slowly on the paper machine. The most reliable results are obtained within the CF number range 30-850.
