Automobile atomization refers to the condensation of volatile substances discharged from automobile interior parts and materials on glass. Automobile interior materials, such as leather, plastics, textiles, adhesives for bonding materials, etc., all contain some volatile substances, especially under the irradiation of sunlight, the temperature inside the car will rise, which will aggravate this volatilization. Volatile gas condenses on the window or windshield, causing poor vision, which will affect the driver's vision and driving safety. Some volatile substances will affect the health of drivers and passengers. In order to control the generation of volatile substances reasonably, it is necessary to carry out atomization test on the materials used in automobile interior, and the materials exceeding the standard will not be used in automobile interior.
