The waterproof and breathable membrane can effectively resist the adverse effects of pressure differences caused by temperature changes.The use of waterproof and breathable membrane can quickly balance the pressure inside and outside the shell when the ambient temperature and pressure change.In gas and electrochemical sensors, waterproof vents prevent dust, dirt or liquids from intruding into the sensing head.At the same time, the waterproof and breathable membrane allows gas to pass through the membrane immediately, ensuring that the sensor response speed remains constant and preventing errors and delays in measurement results.

Waterproof and breathable membranes have many uses, mainly in the field of electronic products. The main purpose is to ensure dustproof, waterproof, breathable and heat dissipation of electronic products.The waterproof and breathable membrane can help these electronic products to be waterproof while maintaining sufficient breathability, so that the electronic products are always sealed and the function of the waterproof and breathable membrane can be fully utilized.

Test principle:

1.Inside a factory compressed air street flow tester;

2.By real water testing machine0.6~1.2MPaThe compressed air pressure is adjusted to50KPAor a suitable pressure;

3.Before the test, the upper mold cylinder drives the upper mold to press on the product to fix it, and the side cylinder drives the sealant to press on the back side of the test.MICThe sealant on the hole is formed between the hole and the hole.1a sealed cavity;

4.Use a real water testing machine to first perform a vacuum treatment in the sealed cavity to detect whether there are any defects such as blocked holes in the waterproof and breathable membrane. If not, perform a waterproof test to produce50KPAThe pressure pushes the water in the water pipe to act onMICon the surface of the waterproof and breathable membrane in the hole (pre-inflated and tested), and turn off the inflation source; after voltage stabilization6Seconds, test the pressure drop of the water pressure in the water pipe7Seconds, the tester determines whether the waterproof and breathable membrane is leaking based on the pressure drop in the water pipe.

HWThe true water tester is an instrument specially developed by Hirays for true water testing of waterproof and breathable membranes. It not only has the function of generating simulated test water pressure, but also can automatically identify whether the waterproof and breathable membrane is leaking under the action of simulated water pressure. The measurement results can be quantified, which improves the current drawbacks of manual confirmation and makes automated testing, judgment and production of products with waterproof and breathable membranes possible. It improves efficiency for our customers while ensuring product quality.
