Overview
Standard dissociation meter (model ZY-YLD) is an instrument used to determine the filtration rate of various Pulp water suspensions. It is expressed by the concept of dissociation (CSF) to reflect the fiber Refining or fine grinding. The instrument is made of all stainless steel and has a long service life. It is widely used in paper industry production inspection, process formulation and scientific research experiments.
Features
1. All stainless steel manufacturing, strong durability; 2. Filter in strict accordance with the TAPPI T227 standard precision manufacturing, Accuracy is high; 3. Provide test values suitable for the production control of grinding wood pulp; 4. Widely used in various chemical pulp in Refining and seminal pulp process water filtration change detection; 5. Structure includes water filtration chamber and measurement funnel, stable installation.
Principle
The Canadian standard dissociation determination is based on the specified conditions. The instrument measures the water filtration performance of 1000mL of Stock water suspension with a content of 0.3% and a temperature of 20 ° C. The CSF value is expressed as the volume (mL) of the outflow water from the side tube. The water filtration chamber is made of stainless steel. The bottom is a porous sieve plate and a sealing bottom cover. The top cover is sealed. Pulp outflow from the bottom cover is opened to penetrate the water cone funnel measurement.
Applications
Refining process inspection in paper industry, papermaking process formulation, papermaking pulp experiment in scientific research institutes
Standards
TAPPI T227, ISO 5267/2, AS/NZ 1301, 206s, BS 6035 part 2, CPPA C1, SCAN C21, QB/T1669-1992
Steps
1. Prepare a stock water suspension with a content of 0.3% and a temperature of 20 ° C at 1000mL; 2. Pour the stock into the water filter chamber; 3. Sealing the bottom cover and the top cover; 4. Open the bottom cover to allow Pulp to flow out; 5. Collect the outflow water from the side pipe through the measurement funnel; 6. Measurement of the volume of the outflow water to determine the CSF value.
Notice
• Ensure Stock concentration and temperature meet standard requirements; • Check instrument sealing before use; • Clean filter regularly to maintain Accuracy; • Avoid operating in non-standard environments; • Follow relevant safety operating procedures.
