Significance And Usage Of Canadian freeness tester

Refining of pulp is the crucial stage in the papermaking process. Infact, most of the paper's physical properties vividly depend on the quality and mechanical beating/refining of the pulp. Helping in the process is the pulp freeness testing instrument.

The pulp freeness test determines the rate at which the dilute pulp suspension may be drained. With the measurement of 3g of pulp in 1-litre water. It is precisely the measurement of how rapidly water can drain from a diluted fibre furnishing (pulp) suspension. Canadian freeness tester serves the very purpose of getting the measurements.

This instrument dominates worldwide and is used extensively to evaluate the freeness of the pulp and drainage rate. Where pulp freeness and drainage rate are both parameters of the effectiveness of the paper refining process as it further determines the work done on the pulp during the beating process. The process is viable on several types of pulps in their aqueous form.

What Is a Canadian Freeness Tester?

Canadian Freeness Tester is the instrument to test the rate of drainage of diluted pulp suspension. Relied on while beating/refining different pulps (wood fibre, groundwood and mechanical pulp). The tester gives a Canadian freeness number which is a standard measurement for drainage capacity of different pulp types.

Canadian freeness tester measures the pulp freeness and drainage rate of the diluted pulp suspension. Here the drainage rate is directly related to the surface conditions and the swelling of fibre. The Canadian freeness tester is widely used to note the changes in drainage rate while pulp beating and refining. The tester works as per the standards of ISO 5267/2, CPPA C1, BS 6035/2, TAPPI T 227 (3g pulp in 1l water). It consists of a drainage chamber and a measuring funnel.

Canadian Freeness Tester And SR-Tester

Canadian Freeness Tester and SR-tester are two standards used to determine the pulp freeness. While both are based on similar approaches, the only difference is the shape of the funnel and while the SR tester dominates in chemical pulp, the Canadian Freeness Tester is for the mechanical pulp. The Canadian freeness tester is designed to become a benchmark to include the precision of a bull’s eye.

Canadian Freeness Tester By UEC

The Canadian type beating and freeness tester by Uec gives a quick and effective measurement of freeness of wood fibre, groundwood and other various kinds of mechanical fibres. Grouped under the category of pulp testing equipment, the Canadian Freeness Tester weighs approx 35 kgs with dimensions 45.0 x 25.0 x 101.0 cm. Applicable standards

ISO 5267/2, CPPA C1, BS 6035/2, TAPPI T 227. A step further, UEC provides ON-DEMAND Std. Mesh, Sealing Gaskets for Upper & Lower Lids, Measuring Cylinder & Calibrated Nozzle.
