How to detect the service life of Vents?

1. Accelerated aging test
Place Vents under conditions that simulate harsh environments, such as high temperature, high humidity, strong ultraviolet rays, etc., to accelerate their aging process.
Regularly test the performance indicators of the membrane, such as air permeability, waterproof performance, mechanical strength, etc., and evaluate its aging degree and remaining service life by comparing with the initial performance.
2. Long-term outdoor exposure test
Install a part of the Vents samples in the actual outdoor environment, and conduct regular monitoring and performance testing.
Observe the changes of the membrane in the natural environment, including color, surface state, performance indicators, etc.
3. Chemical stability test
Expose the membrane to common chemicals to detect its chemical stability and ability to resist chemical erosion.
The type and concentration of chemicals should be selected according to the actual situation that the membrane may be exposed to.
4. Mechanical property test
Regularly test the mechanical performance indicators such as tensile strength and tear strength of the membrane.
The decline in mechanical properties is usually an important sign of membrane aging and approaching the end of its service life.
5. Microstructure analysis
Use equipment such as electron microscopes to observe the microstructure of the membrane, such as pore size, distribution, and membrane layer bonding.
Changes in the microstructure can reflect the performance degradation of the membrane.
