What are the functions of waterproof sound-permeable membrane?

One, waterproof.

The waterproof and breathable membrane has micropores of 0.1-1.0 microns, and the pore diameter is 10,000 times smaller than water droplets, making it impossible for water to pass through, effectively protecting sensitive parts, avoiding liquid erosion, and extending the service life of the product. Effectively prevent water, salt and other corrosion (explanation: refers to corrosion, disappearance, corrosion, etc.), so that sensitive parts of the equipment can safely leak outdoors, and ventilation can be quickly restored after contact with water, oil and other liquids.

Two, breathable.

The pore diameter is 700 times larger than water vapor. While being waterproof, it allows air to pass smoothly, can effectively dissipate heat, prevent fogging on the inner wall of the product, and balance the air pressure in the internal and external spaces. Anti-permeability membrane is a new type of polymer waterproof material. In terms of production technology, the technical requirements for waterproof and breathable membranes are much higher than those of ordinary waterproof materials; at the same time, from a quality perspective, waterproof and breathable membranes also have functional characteristics that other waterproof materials do not have. The densely distributed micropores can effectively block dust while being waterproof and breathable, and the protection level reaches IP67.

Three, dustproof.

Make the protected parts easy to clean and not affected by corrosive pollutants, ensuring the performance and service life of the parts. Waterproof breathable membrane is a new type of polymer waterproof material. From the perspective of manufacturing process, the technical requirements of waterproof and breathable membranes are much higher than those of ordinary waterproof materials; at the same time, from the perspective of quality, waterproof and breathable membranes also have functional characteristics that other waterproof materials do not have. Waterproof and breathable membranes are mainly used in steel structures and wooden structures in the construction field. The domestic market is relatively chaotic. Most of the brands promoted through the Internet do not have the ability to produce waterproof and breathable membranes. Instead, they use fake and shoddy products that are simply compounded of non-woven fabrics and glue. The microporous channels form a mesh-like three-dimensional structure in the membrane, which is evenly and densely distributed, blocking dust and achieving effective dust-proof effect. It can capture particles as small as 0.1 micron.
