Introduction to materials and principles of automotive air conditioning filters
Everyone may not be familiar with the concept of car air conditioning filter. For example, if the air conditioner is compared to the car's breathing system, then the filter element of the car's air conditioner is equivalent to the nose hair in the breathing system. Although it is not very eye-catching, it plays a role in filtering and Plays an important role in blocking harmful substances.
The principle of the car air conditioning filter element is to fold the filter paper into a certain thickness to let the air pass through, thereby isolating the dust and sand in the air. The filter paper is a kind of fiber material, including wood pulp paper (plant fiber), glass fiber paper (glass fiber), Polypropylene paper (polypropylene), etc. Among them, the filter paper made of polypropylene paper is the so-called non-woven fabric.
Of course, if only filter paper is used, the purification effect is very limited. In order to enhance the filtering effect, the filter paper will also be treated with electrostatic electret to enhance the adsorption performance of certain particles. In addition, the car air conditioning filter element also adds activated carbon and other components to Adsorb some carbon oxides, sulfides, formaldehyde, etc.
The role of the car air conditioning filter element in the car air conditioning system is to help the air conditioner filter some impurities, such as dust, carbon oxides, sulfides, etc., to prevent them from entering the compartment, which will have an adverse effect on the performance of the air conditioner, to ensure the cleanliness of the car air conditioning system, Improve the air quality inside the car and ensure the health of the driver.
