Product Introduction:

The Canadian standard free degree refers to the water filtration performance of a 1000mL slurry water suspension with a content of (0.3 ± 0.0005)% and a temperature of 20 ° C, measured using a Canadian free degree meter under specified conditions. The CFS value is expressed in mL of water flowing out of the side tube of the instrument. The Canadian Standard Freeness Tester is used to measure the filtration rate of water suspensions in various types of pulp, and is expressed by the concept of Freeness (CSF). The filtration rate reflects the degree to which fibers undergo beating or grinding. Test values applicable to the production control of ground wood pulp; It can also be widely applied to the changes in water filtration properties of various chemical slurries during beating and refining processes; It reflects the surface condition and swelling of the fibers. The standard freeness tester is widely used in the inspection of the pulping process in the papermaking industry, the formulation of papermaking processes, and various papermaking experiments in research institutes. It is an indispensable measuring instrument for studying pulp and paper making. Execution standard: TAPPI T227 complies with standards: ISO 5267/2, AS/NZ 1301, 206s, BS 6035 Part 2, CPPA C1, and SCAN C21; QB/T1669-1992

Instrument structure

The freeness meter includes a filtration chamber and a measuring funnel with proportional flow, installed on a fixed bracket. The water filtration chamber is made of stainless steel, with a porous stainless steel sieve plate and an airtight sealed bottom cover at the bottom of the cylinder. It is connected to one side of the circular opening with loose leaves and tightly fastened to the other side. The top cover is sealed, and when the bottom cover is opened, the pulp flows out. The cylindrical and filtering conical funnels are supported by two machined open bracket flanges on the bracket, respectively. All materials of the standard free degree tester are made of 304 stainless steel, and the filter is strictly manufactured according to the TAPPI T227 standard with precision, far exceeding the accuracy of some foreign products. Long service life.
