Photocatalyst Filt Screen

Photocatalyst Filt Screen is made by loading photocatalyst on different materials.It is always combined with activated carbon. Activated carbon is used to adsorbed Formaldehyde，Benzene，Ammonia and odors etc through abundant micro-hole on its surface.Shining of light source can stir up oxidation-reduction reaction to degrade the contaminants activated carbon adsorbed. Just like the chlorophyll in the photosynthesis of plants, the photocatalyst only supply the place of oxidation-reduction reaction and there doesn’t have any changes in it. Photocatalyst is a kind of new environmental protection material widely used in air-condition ,air-purification and etc.

Reaction Mechanism:

When the surface of titanium dioxide (TiO2) is exposed by the UV＜388nm light ,its inner will stir up hole-electron pair ,and the hole-electron pair will quickly remove to its surface and activate absorbed oxygen and moisture and occur free radicals (-OH ) and (-O2－).At the moment ,chain degradation reaction occurs between the free radicals and kinds of contaminant and ado each other .For strong oxidation ,the photocatalyst can realize the function of anti-bacteria by destroying the cell membrane.

ProductClassification :

According to base materials ,the Photocatalyst Filt Screen can be classified into the following:

• Polyurethane based alveolatephotocatalyst filt screen
• Paperbasedphotocatalystfiltscreen
• Aluminumbasedhexagonalphotocatalyst filt screen
• Fishnetphotocatalystfilt screen

Activated Carbon Mask

Brief introduction of product:

Activated carbon mask is made of highly effective adsorption and filtration materials, such as activated carbon fiber and activated carbon non-woven. It has main properties as followings :

• Deodorization, gas defence, bacteria filtration and dust prevention etc.
• It is especially suitable for some areas with organic gas, acid, pesticide, pungent gas (SO2, Cl2) and has excellent effect on deodorization and gas defence.
• It can effectively prevent floating dust smaller than 5μm which conventional gauze mask cannot make any effect and each kinds of bacteria spreading through respiratory apparatus. So it is suitable not only for doctors, nurses, patients and so on but also for those who work in chemical industries.

Main type:

According to its material, there are three types :

• Plan-type activated carbon mask
• 3M activated carbon mask
• Activated carbon fiber gauze mask
