CHENCHI CFS-26 Free Degree Tester

Introduction

The new CFS-26 Standard Freeness Tester (Canadian Standard Freeness Tester) is different from the old model in that the upper and lower covers of the barrel are pressed by springs, making operation quick. This equipment is also used to measure the water filtering rate of various pulp aqueous suspensions, and is expressed by the concept of degree of freeness (CSF for short). The drainage rate reflects how well the fiber has been beaten or refined. 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 and pulping experiments in scientific research institutes. It is an indispensable measuring instrument for the study of pulping and papermaking. The instrument is manufactured in strict accordance with GBT12660-2008 "Canadian Standard" Freeness Method for Determination of Pulp Water Filtration Performance and QB 1669-1992 Canadian Freeness Meter Standard.

This instrument provides a test value suitable for groundwood pulp production control; it can also be widely used for changes in water drainage of various chemical pulps during the beating and refining processes; it reflects the surface condition and swelling of the fibers.

Test principle

Canadian standard freeness refers to the water filtering performance of 1000mL of slurry aqueous suspension with a content of (0.3±0.0005)% and a temperature of 20℃ measured using a Canadian freeness meter under specified conditions, and flows out through the side tube of the instrument. The volume of water (mL) represents the CSF value. The instrument is made entirely of stainless steel. long lasting.

Instrument structure

The freeness meter consists of a water filter chamber and a proportional flow measurement funnel, which are installed on a fixed bracket. The water filter chamber is made of stainless steel. The bottom of the cylinder is a porous stainless steel screen plate and an airtight sealed bottom cover. It is connected to one side of the circular tube with a loose leaf and tightly buckled to the other side. The top cover is sealed. , open the bottom cover, and the pulp flows out.

The cylinder and filter cone are each supported by two machined open bracket flanges on the stand.

All materials of the CFS-26 standard freeness Tester are made of 304 stainless steel. The filter is precision manufactured in strict accordance with TAPPI T227 standards, and its accuracy far exceeds that of some foreign products. long lasting.
