waterproof breathable membraneIn the state of water vapor, the water particles are very small, and these water particles can penetrate all the way down the capillary to the other side, causing vapor permeability.If the water vapor condenses into water droplets, the particles will become larger, and the surface tension of the water droplets will act, and the water molecules will not be able to smoothly leave the water droplets, penetrate and reach the other side. In other words, this process can preventThe occurrence of water infiltration, allowing the waterproof and breathable membrane to truly possess the waterproof function.

Waterproof breathable film testing mold

How to judge whether the waterproof and breathable membrane is really waterproof?Users themselves don’t know how to detect it. They only know that if they splash water on the waterproof and breathable membrane, the membrane will not leak. In fact, water is under pressure and will penetrate.The simplest way is to useHirays HC classic series air tightness detectorTest waterproof and breathable membranes so leaky products have nowhere to hide.

Hirays air tightness and waterproof testing equipment test parameters

Let me share with you the equipment and solutions used by Hirays Technology for waterproof testing of waterproof and breathable membranes:

Equipment used: Hirays HC classic series air tightness detector

Solution: Use the flow test method, with a total test duration of 6S, a test pressure of 10KPA, and an upper flow limit of 5L/min. Design the test mold and tooling according to the structure of the breathable membrane.Put the breathable film into the mold, press the start button, then press down the upper mold and close the lower mold to test the breathable film. The breathable film is tested through air intake, deflation and other processes. The instrument will automatically determine whether the test result is qualified or unqualified.

Waterproof breathable membrane test

Through more effective air intake, deflation and other processes to detect waterproof and breathable membranes, the cost is lower, the effect is better, and the quality is higher!It also improves the reliability of the waterproof and breathable membrane in harsh environments.For waterproof and breathable membrane testing, choose Hirays Technology to provide higher protection for your products.
