The Canadian Standard Freeness is worldwide used for determination of the drainability of a dilute pulp suspensions of wet section in the paper machine. The rate of drainage is stated in terms of freeness. The freeness of pulp, as well as drainage rate is the measurable index of the effectiveness of refining process because it … Read more
The pulp freeness tester or slowness tester are extremely sensitive apparatus while applied effectively. Freeness of pulp is a measure of precisely how rapidly water can drain from a diluted fiber furnishes suspension. Drainage rate is related to the surface conditions and swelling of the fibers. On many occasions there is a correlation between freeness … Read more
Paper forming consists essentially of removing water from a dilute suspension of fiber and other materials by filtration, leaving the solids in form of a coherent sheet. Clearly, the rate and separation effectiveness of this water removal from paper fiber webs is significant to the economy of the process of papermaking. Water removal from fiber … Read more
