Background
After interior decoration, various decorative materials and furniture can generate harmful substances such as formaldehyde and the like to a greater or lesser extent, and if the content of the harmful substances for decoration exceeds the standard, serious influence can be generated on human health, such as leukemia and the like.
The existing process for removing decoration pollution such as formaldehyde and the like mostly removes formaldehyde from indoor space and furniture by spraying preparations so as to eliminate harmful substances such as formaldehyde and the like emitted. However, this method usually only temporarily reduces the content of harmful substances in the room, and the harmful substances continuously volatilized from the furniture and the decorating material exceed the standard for a long time, so that even after the aldehyde is removed, ventilation is required for a long time to reduce the content of the harmful substances.
As is well known, artificial boards are the main source of formaldehyde and other harmful substances, and researches show that the boards can effectively prevent the harmful substances in the boards from being emitted after the surfaces of the boards are coated with skins; however, since furniture and various decorative boards have unclosed surfaces such as spliced surfaces, back plate surfaces and open holes, harmful substances such as formaldehyde can continuously diffuse from the unclosed surfaces, and the indoor environment is continuously polluted.
In conclusion, the existing process for removing the decoration pollution such as formaldehyde can only remove the indoor pollutant content temporarily, but is easy to repeatedly exceed the standard, so ventilation for half a year is needed to reduce the pollutant content such as formaldehyde after decoration, the waiting time is very long, and the social cost is very high.
