Waterproof breathable membrane is a product that is breathable and waterproof at the same time.The waterproof and breathable membrane can fully protect the product from dust, oil, and water, and can provide a level of protection.Release gas, balance air pressure, and improve product reliability in harsh environments.There are many extremely small holes on the waterproof and breathable membrane. The density of these holes affects whether the breathable membrane can achieve the waterproof and breathable effect.

At present, flow leak detectors are mainly used to detect whether the quality of waterproof and breathable membranes meets the requirements.Hai RuisiFlow detectorIt can detect whether the amount of product leakage is large or small, and allowing product leakage fully meets the product requirements of waterproof and breathable membranes.

At present, waterproof and breathable membranes are mainly used on mobile phones and watches.With the development of electronic products, in order to increase the quality of electronic products, many businesses have begun to apply waterproof and breathable films to mobile phones and watches.The waterproof and breathable film attached to the mobile phone watch needs to be checked to see if it is properly attached.In many cases, waterproof and breathable membranes are qualified products, but if they are not well-fitted, water will enter the product through the gaps. Therefore, electronic products using waterproof and breathable membranes also need to use a Hirays flow leak detector to detect whether the breathable membrane is well-fitted.

At present, the main functions of Hiraysi flow leak detector have two points:

1. Check whether the waterproof and breathable membrane can meet the requirements. If the breathable holes are too dense, there will be no air leakage.If the ventilation holes are too sparse, water may enter.It plays a role in testing whether the product quality meets the standards.

2. Check whether the waterproof and breathable membrane used on the product fits well.

The test results of the air flow leak detector have nothing to do with the shape and volume of the workpiece being tested. It directly detects the actual air flow of the tested channel.The test parameters of the Hirays air flow leak detector are shown in the figure below:

Air supply pressure 0.4~1.2MPa

Power supply voltage 220v/50hz or 110v/60hz

Instrument model flow type tester HCL-L-P-01

Flow range 0~1000sccm

Pressure adjustment accuracy 0.1kpa

Test minimum resolution 0.1sccm

Hirays Technology currently has five series ofAir tightness testing equipment, it can also provide flow leakage detection function, real water testing function, and a variety of product leakage detection methods. If you are interested in our products, please call Hirays Technology.
