In the hot summer, it is very refreshing to go to the beach or swimming pool and have fun, let the cool sea water and swimming pool bring us extraordinary refreshment. But it is difficult for us to use our mobile phones to take pictures while playing in the water. Since the mobile phones are not waterproof, if they accidentally fall into the water, they will basically be scrapped.
In most people’s minds, the two most feared situations for mobile phone products are falling to the ground and falling into water. The latter is more serious. Once the fuselage is filled with water, it means that it cannot be used normally. Many people purchase waterproof cameras in order to go out and play in the water. In fact, many mobile phones now have good waterproof functions.
The main reason why these mobile phones can achieve this function is to install a layer of electronic waterproof sound-permeable membrane, which is waterproof at the same time. It will not affect sound playback.
Electronic waterproof sound-permeable membrane is a microporous membrane made by calendering, extrusion, biaxial stretching and other methods. The porosity can reach more than 85%, and the air can flow smoothly. The membrane pore size is 0.2-3μm, which can effectively isolate water points, and the waterproof grade can reach IPX7 or above. Protect electronic instruments from becoming unusable due to moisture or water. Compared with other breathable filter materials, it has excellent air permeability.
Electronic waterproof sound-permeable membrane, air filter membrane, ptfe bubble point filter membrane, ptfe coated filter material and other technologies have always been It is the core of the business and plays an indispensable role in many fields such as biopharmaceuticals, equipment, food and beverages, semiconductor processes, and communications. Its pore-forming capacity ranges from 0.1 μm to 1 μm, providing fine filtration, removal of small bacteria and viruses, and waterproof and breathable , sound transmission and other functional solutions.
