Introduction to the Paper Air Permeance Tester
The Paper Air Permeance Tester is an essential tool for determining the air permeability of paper and cardboard materials, making it crucial for industries such as packaging, paper manufacturing, and textiles. This tester uses the Schopper method to measure the flow of air through materials, providing accurate and reliable results for papers and boards with air permeance values ranging from 1×10^-2 to 1×10² µm/(Pa·s). The paper air permeance tester is designed to meet international testing standards, ensuring that the materials meet specific requirements for air permeability, which is critical for their performance in packaging, filtration, and other applications.
The tester is ideal for use with a variety of paper types, including copy paper, cement bag paper, industrial filter paper, and paper bags. However, it is not suitable for rough-surfaced materials, such as creped or corrugated papers, that cannot be securely clamped to prevent leakage.
Key Features
- Precise Measurement: Accurately measures the air permeance of paper and board materials.
- Schopper Method: Uses the standardized Schopper method for consistent, repeatable results.
- Wide Material Compatibility: Suitable for testing a wide range of paper types, including industrial filter paper, cement bags, and copy paper.
- Standards Compliance: Meets multiple international and industry standards for air permeability testing.
- Ease of Use: Simple and intuitive operation for quick testing and data collection.
How the Paper Air Permeance Tester Works
The paper air permeance tester works by clamping a sample of paper or board between two airtight circular gaskets. One side of the sample is exposed to atmospheric pressure, while a small, controlled pressure difference is maintained across the test area. The tester then measures the flow of air through the sample under these conditions, calculating the air permeance based on the airflow rate and pressure difference.
Test Method
- Sample Preparation: The paper sample is clamped securely between the two gaskets to avoid any leakage.
- Pressure Control: A small but constant pressure difference is applied across the sample to simulate real-world conditions.
- Measurement: The tester measures the volume of air flowing through the paper sample over a set time period, calculating the air permeance in micrometres per pascal second (µm/(Pa·s)).
This method ensures that the results are reliable and representative of the paper’s true air permeability, making the paper air permeance tester an essential tool for material performance evaluation.
