The waterproof requirement is simple, it is to prevent water invasion, infiltration, infiltration, inflow or overflow, etc.
The diameter of water molecules is about 0.4mm, which is greater than the pore size of the pore diameter of the size, and water can be passed. The diameter of the water molecule is slightly larger than that of the gas molecule, and the gas can pass through the hole of 0.27-0.39mm.
Many outdoor products need to be waterproof, lines such as LED lamp, LED wash wall lamp, LED guardrail tube, LED point light source, LED project-light lamp, LED outdoor lighting lamps and lanterns, light, waterproof watches, aquatic products, underwater camera, etc., as well as the special industry.
Once the electrical products are in water, there are many problems, such as short circuit, leakage, rust, decay, damaged media price and interference signal. Therefore, water proof generally means to prevent the moisture or water vapor from the outside of the electrical appliance to invade, penetrate and flow into the appliance.
The two concepts of sealing and waterproofing are actually interlinked, but with different emphasis. Waterproofing emphasizes "no entry" to prevent the intrusion, infiltration and inflow of external water or vapor media.
More when we want to use the method of sealing way of thinking, structure, material selection, etc. To ensure that long-term effective waterproof products, reference to traditional, classic, mature sealing technology or means to strengthen the waterproof performance of the LED outdoor lighting products
