Freeness tester

The freeness tester is used to determine the water rate of water suspension of various pulp and is expressed by the concept of CSF. The rate of water filtration is a reflection of the condition that the fiber is beaten or refined. The standard freeness tester is widely applied to the test of beating process in papermaking industry, the making of papermaking technology and various papermaking pulping experiments in scientific research institutes, which is an indispensable measuring instrument for pulp and paper making.The instrument provides a suitable for the production of wood pulp mill test control value; also can be widely used in various chemical pulp beating in seminal plasma and filtrate during changes in water quality; it reflects the surface of the fiber and swelling conditions.

Product features

Canadian standard freeness refers to the determination of water content of slurry suspensions with 1000mL content of (0.3 ± 0.0005)% and temperature 20 degrees C under the specified conditions. The CFS value is expressed by the volume of water flowing out of the side pipe of the instrument (mL). The instrument is made of all stainless steel and has long service life.

The free meter includes a water filter and a proportional shunt measuring funnel, which is mounted on a fixed bracket. Water filtering chamber is made of stainless steel, the bottom of the cylinder is a porous stainless steel plate and an airtight sealing bottom cover, in connection with one side of the flexible hinge, closely on the other side, the top cover is sealed, the bottom cover is opened, the outflow of pulp, bracket flange cylinder and drainage cone opening respectively by two mechanical processing with support bracket.

All materials of freeness tester are made of 304 stainless steel. The filter net is manufactured in strict accordance with the TAPPI T227 standard. The accuracy is far beyond that of some foreign products, and the service life is long.
