Waterproof breathable membrane solutionAs a key functional material that balances the internal and external pressure of equipment, waterproof and breathable membranes have a direct impact on the integrity of their microporous structure and the product's protection level and service life.In fields such as outdoor electronic equipment, automotive lighting, and medical equipment, the sealing failure of the breathable membrane will lead to problems such as water ingress and fogging of the equipment.Hairis provides professional sealing testing solutions for the special structure of waterproof and breathable membranes to ensure that the product achieves reliable waterproofing while maintaining its breathable function.
The breathable valve (breathing valve) needs to balance the internal and external pressure difference and be waterproof and dustproof. The key points of testing and solutions are as follows:
1. Air permeability test
To measure the air permeability under the standard pressure difference to ensure smooth "breathing" and avoid shell deformation or seal damage due to insufficient flow, you can choose the Hairis HC flow-type air tightness detector.
2. Real water test
Through the HW true water detector, severe working conditions such as heavy rain and high-pressure water cannons are simulated to verify whether the waterproof performance meets the standards and ensure "breathability and no water leakage".The main test method is to apply precisely controlled water pressure to one side of the membrane and hold it steady for several seconds.The instrument monitors the pressure attenuation value in the cavity in real time. If it exceeds the set threshold, the waterproofness is determined to be unqualified.
