Shangda SDA(e-PTFE) fIm adopts expanded polytetranuoroethylene to achieve uniform stretching and three-dimensional networkstructure
The diameter of the micropores is 0.1-10um,the molecules of air and water vapor are 0.0004um, and the pore diameter of the (e-PTFE)membrane is 250-25000 times larger than the diameter of the gas, so the gas can pass through, while the diameter of capillaryrain is 500 um, which is hundreds of times larger than the diameter of the micropores of the membraneThese micropores, which are only one twenty-thousandth the size of a drop of water, prevent water, dit and debris from entering (e-PTFE) the membrane. By allowing air to enter and exit the closed enclosure freely, equalizing pressure and preventing water.corrosive liquids,salts and particles from entering the enclosure and damaging the interior of the sealing equipment, our sealingequipment becomes more reliable, safer and more durable.
waterproof breathable membrane main function:
1, waterproof, dustproof, anti-oil, high protection level.
2,chemical resistance, high and low temperature resistance, ant-aging,etc., to improve the rellability of products in harshenvironments.
3, to avoid condensation, fog, improve the use of product life4, heat dissipation and balance pressure difference. Progressive product integrity.
Precautions for installing waterproof and breathable membrane:1.Gloves are required for operation of the breathable membrane of the device. The appearance of the device is clean and free of oil
stains and other pollutants.2. Use tweezers to operate the breathable membrane, and ensure that the breathable membrane is aligned with the center of thepolicy area during installation.
3. Once the device is completed, the breathable membrane must not be moved from the head.
4. After the device is completed, it should be placed for 24 hours before it can be used.
