Description
Technical field
This utility model relates to the technical field of environmental conservation and the healthy prevention, particularly to a kind of mask with haze function.
Background technology
Haze is a kind of atmospheric pollution state, is made up of compositions such as the moisture in air, dust, sulphuric acid, nitric acid, organic hydrocarbon compounds.Recently as the deterioration of air quality, increasing, endangering and increase the weight of occur in haze weather phenomenon, and the degree of concern of haze is increased the weight of by China day by day, and haze is carried out early-warning and predicting as diastrous weather phenomenon by many areas, is referred to as " haze weather ".
Reaching kind more than 20 containing various harmful fine graineds, noxious substance in haze, include acid, alkali, salt, amine, phenol etc., and dust, pollen, acarid, influenza virus, tubercule bacillus, streptococcus pneumoniae etc., its content is tens times of normal atmospheric water droplet.It has been generally acknowledged that the Pm2.5(equivalent aerodynamic diameter particulate matter less than or equal to 2.5 microns) it is " arch-criminal " causing " haze weather ".Public's mode typically taking to wear masks of going out reduces haze to healthy impact.
Tradition mask is for the purpose of crossing filtration resistance dirt.The height of its dust collection efficiency is to fine dust with it, and the barriering efficiency of the respirable dust of especially less than 5 microns is standard.But, some are present in air the Organic substance in aerosol state and antibacterial, virus etc., can go through from the mesh of mask fabric, enter respiratory system, are detrimental to health.
" load nano-TiO disclosed in the utility model2Active carbon fiber fabrics+active carbon layer " be the mask of the haze function of main functionality material, except have conventional mask cross filtration resistance dirt function in addition to, more by nano-TiO2Photo-catalysis capability under ultraviolet light combines with the high absorption capacity of active carbon fibre peacekeeping active carbon layer, it is provided that bacterial virus is killed by this utility model, the decomposition of organic pollution and absorbability.
Nano-TiO2Nontoxic, catalysis activity is high, oxidability is strong, stability good, can effectively utilize solar energy (the 3% of about total sun light intensity) photochemical catalytic oxidation Organic substance.Research shows: at anatase titanium dioxide TiO2And rutile TiO2During mixed proportion about 75:25, nano-TiO2Photochemical catalytic oxidation ability the strongest.Additionally, at nano-TiO2Middle appropriateness doping Fe3+、Mo5+、Ru3+、V4+Etc. transition metal ion, the wave-length coverage of exciting light can be expanded to visible region (about 600nm) from below 387nm, effectively facilitate light-catalyzed reaction；By Photoactive compounds as, thionine, fluorescein derivative etc. be adsorbed in photocatalyst surface, can expand excitation wavelength scope, improve nano-TiO2Utilization rate to solar energy, increases the efficiency of light-catalyzed reaction.
NACF has abundant micropore and huge specific surface area, and its adsorption capacity is significantly larger than the porous adsorbing materials such as zeolite, resin, silica gel, also far above other with type activated carbon product.Based on said structure feature, active carbon fiber fabrics has the strongest absorbability to Organic substance, can be with the organic pollution of the Adsorption even lower concentration of PPm, PPb rank.But due to absorption saturated after must carry out desorption and regeneration and just can be continuing with, have that operating procedure is complicated, easily produce secondary pollution problems.And at modified active carbon fiber area load nano-TiO2, make Organic substance when NACF surface enrichment owing to photocatalytic oxidation is degraded fast and effectively, make active carbon fiber situ regeneration, can effectively solve the problems referred to above.
