Overview
The Canadian Standard Freeness Tester (CFS-26) is a CHENCHI-branded instrument for measuring the filtration rate of pulp suspension. The results are expressed in Canadian Standard Freeness (CSF) values. The instrument is designed with spring-pressed upper and lower covers of the barrel, which is fast to operate. It is widely used in pulping process inspection in the papermaking industry, papermaking process formulation, and pulping and papermaking experiments in scientific research institutes. It is an indispensable measuring instrument for studying pulp and papermaking. The instrument is suitable for grinding wood pulp production control, and can also be used to monitor the change of water filtration properties of various chemical pulps during pulping and semen, reflecting the surface condition and swelling of the fiber.
Features
1. The upper and lower covers of the barrel are designed with spring compression, which is fast to operate.
2. The instrument is made of all stainless steel (304 stainless steel), with a long service life.
3. Filter in strict accordance with the TAPPI T227 standard precision manufacturing, high accuracy.
4. Manufactured in strict accordance with a number of international and national standards.
Principle
The Canadian standard free degree refers to the water filtration performance of a slurry water suspension with a free degree tester measuring 1000mL content of (0.3 +/- 0.0005) % and a temperature of 20 ° C under specified conditions. The CSF value is expressed by the volume (mL) of water flowing out of the side tube of the instrument. The instrument includes a water filtration chamber and a proportional diversion measurement funnel. The water filtration chamber is made of stainless steel, and the bottom is a porous stainless steel sieve plate and an airtight sealing bottom cover. The top cover is sealed, and the pulp flows out after opening the bottom cover.
