標準游離度儀是用於測定各種紙漿的水懸浮液的濾水速率,並由游離度(簡稱CSF )概念表述。濾水速率反映了纖維經過打漿或精磨的情況。標準游離度測定儀被廣泛應用於造紙工業生產中打漿過程的檢驗,造紙技術的制定以及科研院所的各種造紙制漿實驗中,是研究制漿造紙不可缺少的測量儀器。
加拿大標準游離度是指在規定的條件下,用加拿大游離度測定儀測定1000mL含量為(0.3±0.0005)%、溫度20°C的漿料水懸浮液的濾水性能,以該儀器側管流出的水的體積(mL)表示CFS值。該儀器為全不銹鋼製造。使用壽命長。

應用範圍:紙漿、複合纖維

Description

 

Version with digital display, temperature compensation and concentration correction:

 

The Canadian Standard Freeness Tester measures the degree of work done on the fibres during stock preparation (refining) and is therefore a primary tool in the evaluation of the characteristics of pulp. The apparatus consists of a drainage chamber and rate measuring funnel on a sturdy support. 1 litre of pulp suspension at 0.3% concentration drains through a perforated screen plate into a funnel provided with a bottom and a side orifice. The discharge from the side orifice is collected in a graduated cylinder, measured by an ultrasonic sensor and the result displayed digitally. The actual temperature of the suspension is measured simultaneously and the result corrected automatically. Any deviation from 0.3% is entered at the digital control panel before reading the fully compensated result in ml CSF.

 

Test description

 

Place the drainage chamber in position. Place the measuring cylinder in position to receive the discharge from the side orifice. Whilst stirring, transfer 1,000 ml of homogeneous pulp suspension to a clean measuring cylinder. Close the bottom of the chamber of the freeness tester and open the top lid. Mix the sample by closing the top of the cylinder with the hand and invert the cylinder through 180° three times, without losing the stock. As much as possible, avoid introducing air into the stock at this stage. Pour the stock gently but as rapidly as possible into the chamber. At the end of the pouring, the stock should be almost motionless in the chamber. This can be achieved by pouring the stock around the inside of the chamber and finishing the pouring in the centre. Immediately close the top lid, press “Stop” and open the bottom lid. Allow 5 sec to elapse from the time of opening the bottom lid, then press “Start” to begin the test. When the discharge from the side orifice has stopped, the concentration of the suspension should be entered at the digital control panel before reading the fully compensated result in ml CSF.
