When we buy watches, especially when buying children’s watches, we always hear merchants say that the waterproof level is IPXX, and waterproofing is also important for the product quality of the watch. Assure. The so-called waterproof grade refers to the different degrees of waterproofing that can prevent water penetration. For watches, its waterproof performance mainly refers to the degree to which the watch can be waterproof in deep water, and this waterproof grade is divided based on this water depth.
It is used to mark the waterproof level of the product in outdoor, diving, and many other instruments and equipment, and is a common technical indicator. How to classify waterproof levels: How to classify waterproof levels? There are 9 levels of waterproofing, represented by IPXX, and X represents the level of 0-9. Dust-proof grade (represented by an It will not enter the interior. Many watches now achieve IPX7 protection. You may not know exactly what the protective function of this material is Electronic Waterproof and Breathable Membrane.
Electronic waterproof and breathable membrane (ePTFE expanded polytetrafluoroethylene) is a polymer porous waterproof material made of ptfe polymer. Currently Regardless of domestic and foreign technologies, the small pore size of the waterproof and breathable membrane is 0.1 micron, and the diameter of the water vapor molecule is about 0.0004 microns (μm), so the Electronic waterproof and breathable membrane cannot block water vapor. YouElectronic waterproof and breathable membrane has three major functions: Waterproof: 0.1-1.0 micron micropores, the pore diameter is 10,000 times smaller than water beads, making it impossible for moisture to pass through, well protecting sensitive parts and avoiding liquid erosion. Improve product service life. Breathable: The micropore diameter is 700 times larger than water vapor. It is waterproof and allows air to pass smoothly, which can dissipate heat well, prevent fogging on the inner wall of the product, and balance the air pressure in the internal and external spaces. At the same time, breathable products can also prevent liquid and dust from entering, making it waterproof and dustproof.
YoukeElectronic waterproof and breathable membrane products are widely used in electric shavers, electric toothbrushes, water absorbers, and wet and dry vacuum cleaners , water purifiers, soy milk machines and other small household appliances, the protection level is IPX7. Products used in electric shavers and electric toothbrushes are mainly adhesive-backed waterproof and breathable membrane products. Products used in water absorbers, wet and dry vacuum cleaners, water purifiers and soymilk machines are mainly press-fit waterproof and breathable plugs.
