Catalysis material, further relate to the catalysis material preparation method and its to indoor air pollutants carry out photocatalytic degradation
In application.
Background technique
Airstrainer (Airstrainer) be lenticular honeycomb structure, can be widely applied to air-conditioning, air purifier or
Air filtering system in the equipment such as fresh air system.Airstrainer is divided into thick effect, middle effect, sub- efficient, efficient four types, root
The airstrainer of different number is installed in a pipeline according to air volume, fillter section is mounted in central air-conditioning system,
Feeding room air dust particle is filtered out, to reach the high-quality of room air.Airstrainer is typically mounted at air-conditioning
Among system air supply duct, the prefilter equipment that thick effect and middle effect air filtration section are used as plays protection high efficiency filter section
Effect, while also having good effect to noise elimination.High efficiency filter section should match front end pretreatment filtration equipment during installation, while right
Noise elimination effect is more preferable.Filter material in filter screen is generally fibrous material, and filter screen more than H11 grade is generally PP, compound PP-
PET, terylene and glass fibre etc. plant material.Feature is: dust containing capacity is big, filtering accuracy is high, can need to be processed into according to client
Various sizes and shape are suitble to different types to use.Strainer outline border is made of firm, moisture-proof hard material, it is ensured that Bu Huibian
Shape, rupture, distortion.When filtering net surface is very dirty, washed.Son is put into clear water and dish washing liquid in rinse bath, incited somebody to action
Strainer, which is put into slot, all to drown.It is rinsed several times, until finally being rinsed with clear water without dirt until water is clearly
Only, it takes out and is placed on stainless steel barrier draining, then tile and dry in the shade on the top of the shelf.
Photochemical catalyst is usually used for air purifier by using following manner by photocatalytic air filtering material at present:
(1) on by photocatalyst on the carriers such as active carbon, non-woven fabrics, harmful gas is adsorbed by porous carrier
Then body, bacterium, virus etc. rely on the catalytic effect of photochemical catalyst again, carry out sterilization or resolving harmful gas.
