Problems solved by technology

It is known that formaldehyde, ozone, and benzene series (such as benzene, toluene, xylene) are the main gaseous pollutants in the closed space, and the catalytic purification method is mainly used in the current purification equipment to treat them; specifically, the catalytic In the purification method, gaseous pollutants are degraded into water and carbon dioxide by catalytic reaction on the surface of the catalyst to achieve the purpose of removing pollutants. Due to the high efficiency and safety of this method, it is widely used in air conditioners, air purifiers, etc. In equipment; for example, the catalytic part of the catalytic component used in the existing air conditioner or purifier, which is a layered structure composed of various substances, and the catalytic part is generally compounded on a carrier such as an electric heating fin, a catalytic module, etc. However, when the air conditioner or purifier operates under complex working conditions, it is often accompanied by phenomena such as vibration, air volume changes, and temperature and humidity changes. For existing catalytic components, between the carrier and the catalytic part, or between the catalytic part The thermal expansion coefficient difference between the layer structures, these vibrations, changes in air volume, temperature and humidity changes, etc. will easily lead to problems such as the peeling of the catalytic part from the carrier, or the separation and deformation of the layers of the catalytic part; The product obtained on the carrier has poor absorption capacity for gaseous pollution, which makes the purification efficiency and purification ability of the product relatively low. Of course, there is also a method of impregnating the catalytic part on the carrier, but this In the method, it is impossible to obtain a product with a certain thickness of the catalytic part through targeted processing, which greatly increases the rework rate in the production process of the product, resulting in a decrease in the production efficiency of the product, which is not conducive to its promotion in the production field
