Description
Technical field
This utility model relates to outdoor guard technology field, especially relates to a kind of sensitization discoloration mask。
Background technology
Mask is a kind of hygienic article, refers generally to the air being worn over nose and mouth for filtering turnover mouth and nose, to reach the apparatus of the gas of blocking harmful, abnormal smells from the patient, spittle turnover wearer's mouth and nose, makes with gauze or paper etc.。
The air entering pulmonary is had certain filtration by mask, when respiratory infectious disease is popular, in the environment that dust etc. pollutes during operation, wears masks and has extraordinary effect。
Mask can be divided into air filtering type mask and Gas feeding mask。
Haze, as the term suggests being mist and haze。But the difference of mist and haze is very big。What the aerosol systems of the particulate matter compositions such as dust in air, sulphuric acid, nitric acid caused visual disorder is haze。Haze is exactly gray haze。
The aerosol systems that mist is made up of the small water droplet being suspended in a large number in surface air or ice crystal。Come across autumn and winter season more, be the product of ground layer water in air vapour condensation。The existence of mist can reduce air transparency, makes visibility deterioration, if the horizontal visibility of object is reduced within 1000 meters, just the weather phenomenon of the condensation vapor thing being suspended in surface air is called mist。
Haze, also can make air muddy also referred to as particles such as the dust in gray haze air, sulphuric acid, nitric acid, organic hydrocarbon compounds。The horizontal visibility of object is called mist or mist in this phenomenon of 1000-10000 rice。It should be saturated for forming atmospheric humidity during mist。The light of the mist scattering formed due to aqueous water or ice crystal is little with wavelength relationship, thus mist seems to be creamy white or Bluish white and Lycoperdon polymorphum Vitt。
Haze weather is a kind of atmospheric pollution state, and haze is the general statement to suspended particulate substance content overproofs various in air, and especially PM2.5 is considered as " arch-criminal " that cause haze weather。Along with the deterioration of air quality, increasing occurs in thick weather phenomenon, and harm increases the weight of。The many areas of China are incorporated to mist together as diastrous weather early-warning and predicting thick weather phenomenon。It is referred to as " haze weather "。
Sulfur dioxide, nitrogen oxides and pellet these three are that haze mainly comprises, and the above two are gaseous contaminant, and last particulate matter is only and increases the weight of the arch-criminal that haze weather is polluted。They and fog combine, and allow sky moment become dusky。The english abbreviation of particulate matter is PM, and Beijing monitoring is PM2.5, the namely equivalent aerodynamic diameter contaminant particle less than or equal to 2.5 microns。
Haze is mainly made up of sulfur dioxide, nitrogen oxides and pellet these three, and they and fog combine, and allow sky moment become gloomily gloomy。The english abbreviation of particulate matter is PM, and Beijing monitoring is fine particle (PM2.5), namely the equivalent aerodynamic diameter contaminant particle less than or equal to 2.5 microns。This granule itself is a kind of pollutant, is again the carrier of the noxious substance such as heavy metal, polycyclic aromatic hydrocarbon。
The distribution ratio of haze particle is more uniform, and the yardstick of gray haze particle is smaller, and from 0.001 micron to 10 microns, average diameter is approximately in 1-2 microns, and be invisible to the naked eye the aerial particulate matter floated。Due to molecular hazes of grain such as dust, sulphuric acid, nitric acid, the longer wavelengths of light ratio of its scattering is more, thus haze seems to be yellow or orange ash
Selecting mask to consider dust collection efficiency, the height of the dust collection efficiency of mask is to fine dust with it, is especially standard to the barriering efficiency of the respirable dust of less than 2.5 microns。Because the dust of this particle diameter can directly enter alveolar, what health was caused has the greatest impact。Cotton cloth respirator, its resistance dirt principle is mechanical filtration, it is simply that when dust crashes into gauze, through obstruct layer by layer, intercept some big dust particles at Sha Buzhong。For some fine dusts, it is especially less than the dust of 2.5 microns, through going from the mesh of gauze, respiratory system will be entered。Anti-dust respirator, its filtrate NACF felt pan or non-woven fabrics composition, those respirable dusts less than 2.5 microns are in the process of this kind of filtrate。
Selecting mask to consider closed intensity, the design of mask lateral leakage protection is to prevent air not to be inhaled into by filtration considered technology important document by mask and human body face gap。Air is just as current, and where resistance is little just first to where flowing。Very moment hood shape is not closely sealed with face, and the danger in air equally can leak at never closely sealed place, enters the respiratory tract of people。So, even if you select the mask that filtrate is good again。Also your health cannot be ensured。External many statutory standards specify, workman should be periodically subject to the test of mask adaptation。In order that ensure that workman selects suitable mask few greatly and wears mask by correct step。
Selecting mask to consider comfortable wearing, such work talent conference is gladly adhered in working space wearing and improving its work efficiency。Now external exempt from maintenance type mask, need not clean or change parts, when resistance dirt is saturated or mask damaged after namely abandon, so not only ensure the health of mask but also eliminate workman to maintain the time and efforts of mask。And many masks all adopts arcuate in shape, not only can guarantee that and enter the closely sealed good of face shape but also certain space can be retained at mouth and nose place, wear comfortable。
Continuous deterioration along with environment, haze weather constantly increases, people go on a journey the people with mask get more and more, in order to ensure that people's self is healthy, especially in autumn and winter season, major part has all brought mask, and the mask color on general market is single, single when trip do not have any novelty, and the color of mask and flower pattern change are all without significantly change。
