Problems solved by technology

[0002] The performance of the current air conditioners and air purifiers has strict antibacterial and purification requirements. The air conditioner filter has a certain function of removing formaldehyde, and the air conditioner can be labeled as "purifying air conditioner". The "purification" electrical appliances on the market were spot-checked, and the test results showed that many brands of "purification air conditioners" could not meet the requirements of the national standard. The performance of the machine is far from the parameters required by the national standard, and even some functional electrical appliances have no formaldehyde removal function at all. It is necessary to develop new purification technology to make the purification function of the whole machine meet the requirements of the national standard.
[0003] In addition, the formaldehyde removal catalyst coating of the prior art, in order to maximize the effect of the catalyst during production, the proportion of adhesive added is small, and the catalyst coating will fall off during use, reducing the formaldehyde removal performance of the filter. Moreover, the catalyst can easily absorb moisture in the air when it is exposed to the air, which greatly reduces the activity of the catalyst; but if too much adhesive is added, or the adhesive is improperly selected, the catalyst will be completely wrapped and cannot exert its deodorizing effect. The efficacy of formaldehyde

Abstract

The invention discloses a method for removing a formaldehyde coating and a formaldehyde removal filter. A formaldehyde removal catalyst coating and a catalyst fixing layer are arranged on a carrier. The catalyst fixing layer is arranged outside the catalyst coating. The catalyst fixing layer fixes the formaldehyde removal catalyst coating to prevent catalyst coating falling-off and catalyst activity reduction because of catalyst exposure to air and absorption of water. The catalyst fixing layer does not cover and wrap the formaldehyde removal catalyst coating so that formaldehyde removal effects are guaranteed.

Description

technical field [0001] The invention relates to a formaldehyde removal process method, in particular to a formaldehyde removal coating method and a formaldehyde removal filter prepared by applying the method. Background technique [0002] The performance of the current air conditioners and air purifiers has strict antibacterial and purification requirements. The air conditioner filter has a certain function of removing formaldehyde, and the air conditioner can be labeled as "purifying air conditioner". The "purification" electrical appliances on the market were spot-checked, and the test results showed that many brands of "purification air conditioners" could not meet the requirements of the national standard. The performance of the machine is far from the parameters required by the national standard, and even some functional electrical appliances have no formaldehyde removal function at all. It is necessary to develop new purification technology to make the purification fun...
