Description

technical field [0001] The invention relates to the technical field of metal materials, in particular to a corrosion-resistant high-strength aluminum alloy outer cover material for an air purifier. Background technique [0002] Air purifiers, also known as "air cleaners", air fresheners, and purifiers, refer to decoration pollution that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.) , bacteria, allergens, etc.), household appliances that effectively improve air cleanliness, are mainly divided into household, commercial, industrial, and building. [0003] The air purifier is mainly composed of motor, fan, air filter, outer cover material and other systems. Its working principle is: the motor and fan in the machine circulate the indoor air, and the polluted air passes through the air filter in the machine. Pollutants are removed or adsorbed, and the air is continuously ionized to generate a large n...
