Some closer year come, change as the configuration of economic development and society. More and more people leave his native place, the saving that spent big half a lifetime bought a house in a certain city. The half a lifetime below this plan is in this house live together with the family of close kin, let the child stay behind no longer, old person also no longer empty nest, but increasingly serious decorate contaminative formaldehyde to exceed mark to let serious illness permeate an innumberable families through decorating however.
And the case that news reports to formaldehyde exceeds bid one after another recently: Jiangsu 5 years old of girls are little intelligent was sufferred from to go up by diagnose leukaemia, the building of her home had decorated 7 years many, however still the heat that formaldehyde exceeds mark to cause is discussed still have not drop in temperature. Another field of vision that entered everybody again because of the case of " of formaldehyde " do evil because the employee in the A recently hires the formaldehyde room sicken of freely to die. 2 months will produced so distressed case to also cause social attention again and again, so is formaldehyde basically from where to come? Can you administer formaldehyde completely? What kind of harm does formaldehyde have to the person? Small make up everybody popular science the knowledge of formaldehyde.
Normally we look report and can say on a few articles, the volatilization of formaldehyde is periodic be in 3, 15 years, feel very long. But really are all formaldehyde pollution source of release 3, 15 years? Actually otherwise, cent is the contaminative source of release of formaldehyde long-term source of release and short-term source of release.
The long-term source of release of formaldehyde includes those who use to decorate all sorts of man-made board, man-made board furniture, compound floor, the formaldehyde that contains among them volatilizes period can achieve 3-15 year long, must want to undertake settlement through effective processing. The short-term source of release of formaldehyde includes the formaldehyde in curtain, wallpaper, mattess and paint face to wait, the formaldehyde that contains among them volatilizes period control basically in 1 year. The formaldehyde in these article is general content is not high, volatilize period not long, allow manageability relatively.
Before we need to be in only, control formaldehyde content to the country indoor safety enters mark fiducial value to go, (0.1mg/m3 of indoor air quality) .
Main to the harm of human body show is in formaldehyde have a headache, giddy, lack of power, disgusting, vomiting, bosom frowsty, eye is painful, weep, guttural difference of accept of painful, stomach, heart-throb, insomnia, lose weight, memory drops and plant nerve is disorder etc; Pregnant woman is long-term and inspiratory can bring about gestation to be asked for integratedly, fetal deformation, die even, female menstruation intelligence of disorder, children drops the major disease such as leukaemia cancer is caused below severe case.
So how should after be being entered, we go to effective processing formaldehyde? Small make up also summarize a result of these 2 kinds of methods apparent, the hope can help each owner.
Open a window ventilated it is opposite effectual, it is to pass airy current, indoor harmful material eduction, reduce the concentration of indoor pollution thereby. But, ventilated can the formaldehyde element that " takes away the dissociate in " air, and the root question of formaldehyde did not get settlement however. So, if rely on ventilated law to remove formaldehyde only, open a window continuously with respect to need, cannot discontinuous, once stop, indoor pollution can appear again repeatedly. Plus winter chill, time opening a window is limited, accordingly, ventilated law can assist a method as a kind only. But should hold to a window only ventilated effect is distinct still.
2. purifies a bag to cooperate ventilated effect except aldehyde solid state is most effectual, advocate if the formaldehyde on chest of sofa woodiness furniture volatilizes hard,go out, the green solid state that do not have care wraps its surface to having rich small hole structure. Can active adsorption is decomposed, and solid state purifies packet of main good point not to need to change for a long time, service life is long, can use 3 years of above commonly, need not fear after be entered formaldehyde surpasses the case of mark, this is opposite for purify air than what the effect of activated carbon can last apparently.
