Researching the filter screen loaded with the photocatalytic material characterized by high decomposition efficiency, low preparation cost and wide application range has a high practical value. The filter screen loaded with the photocatalytic material comprises a glass fiber screen (1) and a silver-ion modified bismuth vanadate film layer (2) covering the glass fiber screen. The utility model is applied to the filter screen loaded with the photocatalytic material.
Description
technical field:
the utility model relates to a kind of screen pack of load photocatalyst material.
background technology:
photocatalyst [Photocatalyst] is the compound word of light [Photo=Light]+catalyst (catalyst) [catalyst].Photocatalyst is a kind of general name with photosemiconductor material of photo-catalysis function, is the current ideal material of administering in the world indoor environmental pollution.In recent years, BiVO

itself is nontoxic.
the mankind spend indoor the time more than at least 70%, and urban population has surpassed 90% in the indoor time of spending, and especially infant and the old and the weak handicapped person are longer in the indoor time.But the concentration of indoor air pollutants (common as toluene, benzene, formaldehyde etc.) being 2～5 times of outdoor pollutant levels, is dozens or even hundreds of times of outdoor pollutant in some cases.Since the seventies, in developed country, so-called " harmful building syndrome (Sick Building Syndrome, SBS) " having occurred, is exactly the performance of room air pollution potential problems.Along with socioeconomic, develop rapidly, the modern improves constantly the pursuit of high-quality life, and the Chinese real estate development is swift and violent, has brought the flourish of building decorating industry.The various health problems that current indoor pollution causes have become outstanding public health problem.
to sum up, the screen pack of studying the photocatalyst material of a kind of high de-agglomeration efficiency, low preparation cost, applied range has higher practical value.
summary of the invention:
the purpose of this utility model is to provide a kind of screen pack of load photocatalyst material of the photocatalyst material with high de-agglomeration efficiency, low preparation cost, applied range.
above-mentioned purpose realizes by following technical scheme:
a kind of screen pack of load photocatalyst material, its composition comprises: glass fiber mesh, the pucherite thin layer of silver ion modification coats described glass fiber mesh.

beneficial effect:
1. the utlity model has cut out conveniently, shape is adjustable, decomposition efficiency is high, preparation cost is low, applied range.
the screen pack of photocatalyst material of the present utility model has the screen pack of the photocatalyst material of high de-agglomeration efficiency, low preparation cost, applied range, the utility model, for family, office, medical treatment, food and drink, market, vehicle etc., has higher practical value.
the accompanying drawing explanation:
accompanying drawing 1 is the structural representation of this product.
accompanying drawing 2 is section structure schematic diagrames of the screen pack of load photocatalyst material in accompanying drawing 1.
the specific embodiment:
embodiment 1:
a kind of screen pack of load photocatalyst material, its composition comprises: the pucherite thin layer 2 of silver ion modification coats described glass fiber mesh 1.
the screen pack of described load photocatalyst material, with glass fiber mesh, by form the pucherite thin layer of one or more layers silver ion modification on its surface, the number of plies between 1 layer-15 layers for example, it is raw material that the pucherite thin layer of silver ion modification be take bismuth nitrate, silver nitrate, ammonium metavanadate, citric acid is complexing agent, with sol-gal process, prepares BiVO
