Now a new 400W indoor lighting is launched, which requires a protection level of IP65 or above. To achieve such high protection (dustproof, waterproof) level requirements, a good way is to design the lighting fixtures to be fully sealed and use waterproof and breathable membranes for car lights to ensure that various electronic components inside are not protected from The influence of the external environment ensures the normal operation and long life of lighting fixtures. But if the system is completely sealed, problems arise. The lighting fixtures will generate a large amount of heat during use. When the lighting system is frequently started and stopped, the rapid changes in the internal temperature of the fixtures will cause significant changes in the internal pressure. Some data show that a start-stop cycle of the lamp may form a negative pressure of up to 20Kpa internally, or even higher. Such pressure changes will have a negative impact on the sealing parts of the lamp and related internal parts, making it difficult to ensure its long-term normal work.
Car light waterproof and breathable film is formed using a special two-way stretching process. There are many Micropores. The diameter of these micropores is larger than that of air molecules, so gases can be exchanged normally. In this way, the heat generated by the gas inside is taken out, and then the cold outside air enters. This is a dynamic balance.
Car light waterproof and breathable membraneFor clothing applications, polytetrafluoroethylene is used as raw material and is expanded into a microporous The film is then laminated on various fabrics or paper substrates using a special process to make it a new type of material. The polytetrafluoroethylene clothing membrane must not only be moisture-wicking, breathable, and comfortable to wear, but also protect medical staff from infection by various contaminants such as viruses and microorganisms during diagnosis and treatment, resist the intrusion of water, alcohol, and blood, and prevent Dust gets in.
