Description
Technical field
The utility model is related to ceramic technology fields, and in particular to a kind of photocatalyst film composite ceramics.
Background technology
Indoor environment is bad to be caused there are many factor, and interior decoration pollution object, bacterial virus are gathered in dark moist corner etc.,
It is increasingly prominent in the case of current overall situation complexity.Air pollution caused by indoor furniture for example formaldehyde, benzene,toluene,xylene,
Volatile organic compounds（VOC）Deng main to be hidden in plank, emulsion paint, wallpaper, adhesive that interior decoration uses etc. deeply.Separately
One serious threat health be bacterial virus in indoor environment aggregation, residual, especially foods such as kitchen and toilet
It shelves, position moist, air circulation is poor, is also easy to produce peculiar smell etc., these easily cause health problem, are also increasingly occupied
Common concern firmly.
In many measures for improving indoor environment, photocatalyst with the excellent properties such as its stable and durable effect, easy to use,
It is deep to be made a pet of by consumers in general.Photocatalyst can generate similar photosynthetic light-catalyzed reaction, produce under the irradiation of light
