How do 4S stores remove formaldehyde from new cars?
1 Answers
4S stores use the following methods to remove formaldehyde from new cars: 1. Photocrystalline: Photocrystalline is a thermoelectric composite material for vehicle air purification, suitable for in-car pollution control. Since exposure to sunlight can rapidly increase the temperature inside the car, adsorption products may experience desorption. Photocrystalline has a desorption temperature above 100 degrees, addressing the shortcomings of mainstream adsorption materials. In terms of treatment speed, the addition of high manganese oxides enhances its decomposition capability, continuously breaking down harmful substances with strong and fast treatment capabilities. 2. Activated carbon: Activated carbon has strong adsorption properties, effectively absorbing harmful substances like formaldehyde from the air. It is small in size and can be placed anywhere. However, activated carbon has a service life of only 6 months and cannot continue to adsorb once saturated, requiring constant replacement of new carbon packs. 3. Photocatalyst: The photocatalyst removal method uses ultraviolet light to catalyze the decomposition of harmful substances like formaldehyde. Its advantages include no saturation, strong decomposition capability, and no secondary pollution. However, it is important to note that it must be used under sufficient ultraviolet light exposure, as insufficient UV light will weaken its treatment capability.
