Learn anti-haze window screening of good performance.
Background technology
Pollution of the large-scale industrial production to air is especially serious so that domestic haze weather frequency is existing.Wherein, PM2.5
(particulate matter of the equivalent aerodynamic diameter less than or equal to 2.5 microns) is considered as " arch-criminal " for causing haze weather, is also
What people most paid close attention to.PM2.5 can reach pulmonary deposition by upper and lower respiratory tract and bronchus, and even with alveolar human body is entered
Blood, is enriched heavy metal, acidic oxide, organic pollution etc., bacterium, virus etc. also easily at thin in addition on particulate matter
Assemble on grain thing, therefore PM2.5 causes significant threat to health.
To prevent harm of the PM2.5 to human body, people when haze weather is outgoing more wear haze-proof mask.But relevant report
Show, in haze weather, indoor PM2.5 indexs are simultaneously not less than outdoor, in addition it is more serious than outdoor.It is presently used for Interior Space
Between cleaning equipment be mainly air purifier.But, indoor air purifier needs to close door and window when in use, with
Realizing the air of the interior space of the air purifier to closing carries out a certain degree of purification, and common air purifier can not
It is enough that outdoor fresh air is imported into interior.This there is a foul indoor air cannot be with lacking that outdoor fresh air is exchanged
Fall into, be unfavorable for the physical and mental health of people in closing space for a long time.
Window screening is the gauze on a kind of mounted on a door or window, its basic role be indoors outer air exchange while
Prevent what mosquito from getting in.But common window screening can not reach the effect of anti-haze, once there is haze weather, people will not
Obtain and do not select to close door and window, which hinders indoor and outdoor air exchange, be unfavorable for the physical and mental health of people.
