With the advancement and development of science and technology, more and more smart devices have entered our lives, including high-tech products such as phones and watches. Do you know how this product generally improves its waterproof performance? It’s very simple, just use Phone Watch Waterproof Sound-Permeable Membrane.
Just like speakers are widely used in life, in order to adapt to different usage environments, walkie-talkie speakers have also been developed to a certain extent. development of. In order to protect the walkie-talkie products from water, dust, dirt and impurities, the waterproof speaker waterproof membrane of the walkie-talkie plays a big role. The speaker waterproof membrane ensures that the walkie-talkie can transmit high-quality sound even after it is exposed to water.
Structurally, Phone watch waterproof sound-permeable membrane can be divided into microporous materials (including polytetrafluoroethylene PTFE microporous membrane, polyurethane PU microporous membrane, ultra-dense fabric, polyethylene PE porous membrane) and non-porous materials (thermoplastic polyurethane TPU hydrophilic non-porous membrane), as well as microporous and non-porous composite materials (PTFE microporous membrane + PU non-porous membrane, fabric + hydrophobic treatment agent coating, PP + PE Porous membrane + PP laminate composite).
The produced waterproof sound-permeable membrane for phones and watches has small and uniform pore size, stable microporous structure, and a porosity of up to 80%~90 %, the filtering accuracy can reach above U15 level, or even reach U17 level. The surface filtration efficiency reaches 99.9%~99.999%, and the fiber filament diameter can reach 0.1um-0.3um nanometer level. Therefore, the surface has a good filtration function and uses physical principles to filter particles in the air. It can operate at a continuous operating temperature of 240°C and an instantaneous temperature of 260°C. We sincerely welcome friends from all walks of life at home and abroad to visit our company and discuss business and common development.
