Sponge air permeability measurement system

Meet the standards:

GB/T 10655-2003Polymer porous elastic material Determination of air permeability

Product Overview:

This device is suitable for polyurethane foam cottonPVCTesting of air permeability and air resistance of materials such as leather, textiles, and non-woven fabrics. By measuring, the requirements for controlling the physical properties of materials can be achieved to meet the practical application needs of the product. In addition, it can also be used for testing the breathability of separation membranes, sponges, carpets, non-woven fabrics, paper, and leather.

Technical Specifications ：

1. Two test modes: constant pressure difference and constant flow measurement
2. Pressure sensor: high-precision electronic airflow and pressure sensor ensure the accuracy of test data

3Operating interface: The system adopts touch screen control, which is easy to operate and convenient to use

4Data Printing: Equipped with a micro printer that can print test data

5Differential pressure measurement range:0～1 kPa

6Flow measurement range:0～1800 L/h

1. Vacuum pumping: negative pressure system, vacuum pump limit-6*10^-2, pumping speed1L*S^-1
2. Sample thickness:（0-99.9）mm
3. Sample size: square cylindrical, side length（102±1）mmThe thickness is（50-100）mm.
4. Sample quantity: Take three samples from different parts of the same sample

original reason ：

methodA

Stabilize the airflow passing vertically through the sample at a constant flow rate, measure the pressure difference formed on both sides of the sample under this condition, and calculate parameters such as air flow resistance.

methodB

By adjusting to create a constant pressure difference on both sides of the sample, measure the airflow rate passing vertically through a given area of the sample for a certain period of time, and calculate parameters such as air permeability.
