Abstract
The present invention relates to an air filter using glass and aluminum substrates coated with a photocatalyst and a manufacturing method therefor. Disclosed is an air filter, which is more efficient in removing organic gas from air by using optical properties of a glass material and surface reflectance of an aluminum metal material to actively utilize the transmission and reflection of the light that is limitedly provided.
Claims8
A method of manufacturing a glass or aluminum structure air filter employing a photocatalytic precoat,
- wherein a photocatalytic topcoat is applied to a glass or aluminum structure using a photocatalytic precoat solution as a binder, and
- the precoat solution is prepared by mixing and reacting a photocatalytic topcoat solution, tetraethyl orthosilicate (TEOS), and methyl triethoxysilane (MTEOS), adding tetra-n-butyl titanate (TnBT), and then inducing a reaction.
