The standard freeness Tester (Canadian Standard Freeness Tester) is used to measure the water filtration rate of the aqueous suspension of various pulps, and is expressed by the concept of freeness (CSF for short). Drainage rate reflects how well the fiber has been beaten or refined. The standard freeness Tester is widely used in the inspection of the beating process in the papermaking industry, the formulation of the papermaking process, and various papermaking pulping experiments in scientific research institutes. It is an indispensable measuring instrument for the study of pulping and papermaking.
The instrument provides a test value suitable for the production control of groundwood pulp; it is also widely applicable to the change of drainage of various chemical pulps in the process of beating and refining; it reflects the surface condition and swelling of the fiber.
Canadian standard freeness refers to the water filtration performance of 1000mL slurry water suspension with a content of (0.3±0.0005)% and a temperature of 20°C measured by a Canadian freeness Tester under specified conditions. The volume (mL) of water represents the CFS value. The instrument is made of all stainless steel. long lasting.
The freeness meter consists of a water filter chamber and a proportional split measuring funnel, mounted on a fixed support. The water filter chamber is made of stainless steel. The bottom of the cylinder is a porous stainless steel sieve plate and an airtight sealed bottom cover. It is connected to one side of the Yuantong with a loose leaf and fastened to the other side. The top cover is sealed. , open the bottom cover, the pulp flows out.
The cylinder and filter cone are respectively supported by two machined bracket flanges with openings on the bracket.
All materials of the standard freeness Tester are made of 304 stainless steel, and the filter screen is precisely manufactured in strict accordance with the TAPPI T227 standard, with high accuracy. long lasting.
