Paper Beating Degree Detection Tester plays a crucial role in determining the drainability of pulp suspensions, specifically measuring the Schopper-Riegler (SR) number. This highly specialized equipment is designed to measure the drainage speed and performance of pulp, ensuring consistency and accuracy in the papermaking process. Used in various industries including packaging, food, pharmaceuticals, and education, the Paper Beating Degree Detection Tester provides essential data for optimizing the quality of paper products. This product description will delve deeper into the instrument's function, benefits, working principle, and its application across multiple industries.

Overview of the Paper Beating Degree Detection Tester

The Paper Beating Degree Detection Tester is a precision instrument used to determine the drainage performance of pulp in water. This process, commonly known as "beating degree," helps assess the efficiency of the pulp’s fiber preparation. By accurately measuring the Schopper-Riegler (SR) number, this tester helps manufacturers ensure that their pulp products meet the required standards for drainability and fiber treatment.

The SR number reflects the rate at which a pulp suspension drains, which is indicative of the mechanical treatment the pulp fibers have undergone. This metric is essential for evaluating the quality of the paper pulp and ensuring that it meets specific requirements for various applications, particularly in industries such as packaging, pharmaceuticals, food, and paper production.

• Educational Institutions: Research and quality testing in academic settings benefit from the reliable results provided by the tester.

How the Paper Beating Degree Detection Tester Works

The Paper Beating Degree Detection Tester operates by measuring the drainage rate of a dilute suspension of pulp through a wire screen. The key steps in this process include:

1. Pulp Suspension Preparation: A specific volume of pulp in an aqueous suspension is prepared and poured into the tester’s funnel.
2. Draining Through Fiber Mat: The pulp forms a mat on the wire screen as the water drains through. This mat helps determine the drainability of the pulp.
3. Measurement of Discharge: The tester measures the discharge from the side orifice into a calibrated cylinder, which is then converted into a Schopper-Riegler number.
4. SR Number Calculation: The SR number corresponds to the amount of water retained in the pulp, with lower numbers indicating faster drainage and higher numbers showing slower drainage.

The process provides valuable insights into the paper pulp’s quality, helping manufacturers adjust their processes to achieve the desired paper properties.

Standards Compliance

The Paper Beating Degree Detection Tester adheres to several key industry standards that ensure accurate and reliable results. These include:

• ISO 5627-1: This international standard outlines the methods for determining pulp freeness using the Schopper-Riegler method.
• GB/T 3332: The Chinese standard for determining pulp drainability, which aligns with international testing protocols.
• QB/T 1054: A Chinese standard specifically focusing on the freeness of pulp and paper, ensuring the tester meets regional requirements.

Frequently Asked Questions (FAQs)

1. What is the Schopper-Riegler number scale?
The Schopper-Riegler (SR) number measures the drainability of pulp. A discharge of 1,000 ml corresponds to an SR number of zero, while zero discharge corresponds to an SR number of 100. This scale helps manufacturers determine the degree of mechanical treatment the pulp has undergone.

2. What is 'stock' in the pulp beating freeness test?
'Stock' refers to the aqueous suspension of disintegrated pulp used in the freeness test. The consistency of this suspension is critical to ensuring accurate measurements.

3. Why is measuring the Schopper-Riegler number important?
Measuring the SR number is vital for assessing the pulp's drainage performance, which directly impacts the quality of the final paper product. Ensuring optimal freeness allows manufacturers to create stronger, more durable paper.

4. Can this tester be used for all types of pulp?
While the Paper Beating Degree Detection Tester is suitable for most types of pulp, extremely short-fibered pulps, such as well-beaten hardwoods, may produce less reliable results due to fiber loss through the wire screen.

5. How does this tester benefit the packaging industry?
In the packaging industry, maintaining the proper drainage performance of pulp ensures that the paper used for packaging materials is strong, durable, and meets the necessary specifications for protecting products during transportation and storage.
