(Summary description)With the development of science and technology, in recent years, a new product category-drones has "fired". From aerial news, remote sensing surveying and mapping to agricultural plant protection, the use of drones is becoming more and more popular. However, during the flight, the UAV will face strong pressure difference and rain washout conditions, which need to be sealed and breathable to ensure its normal operation or extend its life. In response to these problems, PUW Pu Wei has developed a special air-permeable membrane for drones that can not only breathe quickly but also be waterproof, dust-proof and corrosion-resistant. UAV waterproof special PUW breathable membrane solution: 1. Develop special PUW breathable membranes for UAV market customers to improve waterproof, moisture-proof, anti-corrosion and breathability functions; 2. Provide adequate protection under extreme working conditions, such as high temperature, dampness, coldness, wind and rain; 3. Continuously ventilate, quickly balance the pressure difference between the inside and outside of the cavity to ensure its flight stability and safety; 4. Keep the cavity dry to prevent the flight equipment from being corroded and oxidized, causing other hidden dangers such as poor contact; 5. PUW breathable membrane provides customization for drones, which is convenient and quick to install and disassemble. 1. Waterproof and breathable protection level reaches IP67 or above 2. High air permeability, balanced pressure 3. Reduce and avoid the high temperature caused by internal heat generation and damage the quality of the product itself 4. Extend the service life of the product 5. Block salt crystals, greatly reduce product problems caused by salt corrosion 6. Allow water vapor to leak out, reduce fogging and condensation 7. Quickly and easily install on the shell of various materials Usually the drone control system has an air pressure, which determines the altitude of the aircraft by the ambient air pressure. Therefore, while achieving waterproofing, the drone must also be connected to the external air pressure, air-permeable and waterproof, so many people are now unmanned The machine will use PUW breathable membrane for internal and external pressure communication.
