Description

Antifog haze gauze mask

Technical Field

The utility model belongs to the environmental protection field, especially, antifog haze gauze mask.

Background

Haze, which is a combination word of fog and haze. In 2013, "haze" becomes an annual keyword, in 1 month and 4 times of the year, 30 provinces (district and city) are covered by haze processes, and in Beijing, only 5 days are not haze days. Reports show that only less than 1% of the 500 largest cities in china meet the air quality standards recommended by the world health organization, and at the same time, 7 of the 10 most polluted cities in the world are in china. In 4 days 1 month 2014, haze weather harmful to health is brought into natural disasters in 2013 for the first time by the ministry of national disaster reduction and civilization. Therefore, the haze becomes a shadow which people in China cannot volatilize.

Haze weather is an atmospheric pollution state, haze is a general expression of exceeding the content of various suspended particulate matters in the atmosphere, and especially PM2.5 (particulate matters with aerodynamic equivalent diameter less than or equal to 2.5 micrometers) is considered as an 'allegory' causing the haze weather. Along with the deterioration of air quality, haze weather phenomenon appears increasing, and the harm aggravates. In many areas of China, haze weather phenomena are combined into fog to be used as early warning and forecast of disastrous weather, which is collectively called haze weather.

The haze mainly comprises three items of sulfur dioxide, nitrogen oxide and inhalable particles, and the three items are combined with the fog to ensure that the sky becomes cloudy, heavy and dark instantly. Particulate matter, abbreviated by the english acronym PM, is monitored by beijing as fine particulate matter (PM2.5), i.e. pollutant particles having an aerodynamic equivalent diameter of 2.5 microns or less. The particle is a pollutant and is a carrier of toxic substances such as heavy metal, polycyclic aromatic hydrocarbon and the like. And haze caused by human body inhalation can be as follows:

1. an increased risk of developing cancer; as is well known, the lung cancer probability of smokers is 60% higher than that of common people, and more harmful particles are contained in the haze, so that the haze is more carcinogenic than smoking.

2. Affecting the respiratory system; the respiratory system is most frequently contacted with the external environment, the contact area is large, hundreds of atmospheric particulates can directly enter and adhere to the upper and lower respiratory tracts and lung lobes of a human body, and most of the atmospheric particulates can be inhaled by the human body, 2.5 ten thousand people with heart diseases or poor hearts are investigated in the United states, and after PM2.5 is increased by 10 micrograms/cubic meter, the fatality rate of patients can be increased by 10-27%.

3. Induction of respiratory diseases; the haze is very complex in composition and has hundreds of particles, and the particles enter respiratory tracts through human breath and can cause respiratory tract diseases such as tracheitis and asthma.

At present, in order to solve the haze problem, the main mode is to reduce the inhaled harmful gas as much as possible. People mainly prevent to inhale the haze through wearing the gauze mask when going out in haze day. Antifog haze gauze mask commonly used at present is PM2.5 gauze mask, and its basic structure is: the outer layer is made of an antibacterial fabric, and the material of the outer layer is carbon fiber felt, high polymer fabric, non-woven fabric and the like. The middle layer is a warm-keeping filler, the lowest layer is a PM2.5 filter disc, dust-free granular activated carbon is added in the middle of the filter disc, and the filter disc is treated by a nano-silver bactericide, so that the filterability is about 95 to 99 percent. The PM2.5 mask is mainly made of non-woven fabrics, filter paper and the like, and is mainly made of lead carbon cloth, so that a good gas defense function can be achieved. The haze-preventing mask with the structure has the following defects:

1. the haze prevention effect is weak; the antifog haze gauze mask of this structure, whole face guard is all can be ventilative, filters and only adopts PM 2.5's filter element to filter, and consequently area of breathing freely is big, and the filter effect is weak, and antifog haze effect is weak.

2. Can not be used repeatedly; the PM2.5 mask generally belongs to a disposable mask, and needs to be discarded after being used for one to two times, so that the environmental protection requirement cannot be met.
