DRK261 Standard Freeness Tester (Canadian Standard Freeness Tester) is used to measure the filtration rate of various pulp aqueous suspensions, and is expressed by the concept of freeness (abbreviated as CSF). The filtration rate reflects the condition of the fiber after pulping or fine grinding.   Freeness is one of the methods for measuring the drainage performance of pulp. Generally speaking, the greater the freeness of the paper, the faster the drainage rate. The Canadian standard freeness measurement instrument is similar to the Shore freeness meter, but the absolute dry fiber sampling amount is that the United States and Japan mostly use the Canadian standard freeness, while Europe and my country are accustomed to using the Shore freeness. For 3 grams with a different beating degree, the freeness and beating degree can be converted into each other. 1. The standard freeness tester is widely used in the inspection of the pulping process in the papermaking industry, the formulation of the papermaking process, and the various papermaking pulping experiments of scientific research institutes. It is an indispensable measuring instrument for the study of pulping and papermaking. 2. The instrument provides a test value suitable for the production control of groundwood pulp; it can also be widely applied to the change of the filterability of various chemical pulps in the process of beating and refined pulp; it reflects the surface condition and swelling condition of the fiber . 3. Canadian standard freeness refers to the determination of the water filtering performance of 1000mL slurry aqueous suspension with a content of (0.3±0.0005)% and a temperature of 20°C using a Canadian freeness tester under specified conditions. The volume (mL) of water flowing out of the tube represents the CFS value. The instrument is made of all stainless steel. long lasting. 4. The freeness meter includes a water filter chamber and a measuring funnel that divides proportionally, and is installed on a fixed bracket. 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, which 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. 5. The cylinder and the filter cone are respectively supported by two machined bracket flanges with openings on the bracket. All materials of the DRK261 standard freeness tester are made of 304 stainless steel, and the filter screen is strictly manufactured in strict accordance with the TAPPI T227 standard, and the accuracy is far greater than that of some foreign products. long lasting.
