Description
Technical field
A kind of multichannel respirator, belongs to amenities technical field.
Background technology
In September, 2010, Nasa has announced a global air quality figure.On this figure, global PM2.5 superlatively district in north African and Chinese North China, East China, Central China.
In recent years, PM2.5 particle contamination had become environmental issue of greatest concern.Many areas, the whole nation were once shrouded by haze, and particularly haze weather frequently appears in North China, 30 meters of urban area of Beijing minimum visibility less thaies.Haze weather not only affects Beijing-tianjin-hebei Region, also fails to escape by luck far away from the Jiamusi in northeast, and weather bureau of Kiamusze City last October 11 has been sent dense fog red early warning signal, has occurred the rare foggy weather that visibility is less than 30 meters.From aspect of meteorology, be mist; From environmental protection studying angle, it is haze.Haze weather has had influence on all parts of the country.
PM, is the abbreviation of English word particle part iculate matter, and 2.5 refer to the particle diameter of representative particle.Scientist represents that with PM2.5 in every cubic metres of air, this particle diameter is the content of 2.5 micron particles, and its general unit is every cubic metre of microgram.This value is higher, represents that particulate in air concentration is high, pollutes also more serious.Due to the diameter of PM2.5 particle be less than people hairline thickness 1/20, can be deep into people's lung, and time of staying in atmosphere is long, fed distance is far away, thereby larger to Health Impact
People's respiratory system, be an energy the system of particulate cascade, PM10 enters nasal cavity and can be blocked, PM5 enters throat and can be driven out of.And PM2.5 or less particle can enter bronchus tip, enter alveolar, transfer to whole body by blood, body fluid.Therefore, respiratory system is very responsive for the intrusion of PM2.5 particle.Now, medical circle is reached common understanding both at home and abroad: PM2.5 particle can not only cause the disease of respiratory system, also can cause angiocardiopathy.Its mechanism is after particle inspiration, and lung produces inflammation, discharges inflammatory factor, and inflammatory factor enters blood, directly has influence on heart, has influence on blood vessel or other function.When in atmosphere, the concentration of PM2.5 often increases ten microgram/cubic meters, the excess mortality rate of angiocardiopathy and other relevant diseases, increase about 4/1000ths to 9/1000ths.
The atmospheric physics institute researcher of the Chinese Academy of Sciences introduces: what really cause haze is that particle diameter is the particle of 0.4 micron to 1 micron, and not particle diameter is the particle of 2.5 microns.Reason is that the wave-length coverage of visible ray is 0.4 to 0.7 micron, and when the diameter of ion is during at 0.4 to 0.7 micron, it will scattering and absorbs sunshine, causes On The Deterioration of Visibility Over.Electron microscope demonstration, PM2.5 particle is not that single particle diameter is the particle of 2.5 microns, but the Agglomerate that is less than 2.5 microns by multiple particle diameters.PM2.5 is not a particle, but a particle beams, and except particle diameter is the particle of 2.5 microns, also having particle diameter is the particle of 0.4 micron to 1 micron.
Along with the puzzlement of PM2.5, PM2.5 mouth mask comes into the market fast as the main protection tool of individual.Beijing medicine equipment inspection institute sodium chloride with 0.3 micron in closed environment detects three kinds of mouth masks: the transmitance of common mouth mask is 85.6%; The transmitance of medical surgical respirator is 18.3%; The transmitance of medical N95 mouth mask is 0.452%.Testing result shows to only have medical N95 mouth mask effective to haze, and common mouth mask is inoperative to haze.But N95 mouth mask, because resistance is large, easily causes unsmooth breath, is apprised of and can not arbitrarily wears.
Serious in air pollution, under the environment that haze, sandstorm occur repeatedly, design a kind of infringement that can prevent PM2.5, the respirator of not feeling oppressed while wearing again seems and is even more important.
