Description
Technical field
The invention belongs to technical field of air purification, and in particular to a kind of formaldehyde adsorbent and preparation method thereof.
Background technology
Formaldehyde is mainly used in dyeing assistant and improves wrinkle resistant, shrinkproof result resin finishing agent in fibre.First
Aldehyde can make the bright in colour beautiful of yarn fabric, keep stamp, the durability of dyeing, and crease-resistant cotton fabric, shrinkproof, resistance can be made again
Combustion.Therefore, formaldehyde is widely used in textile industry.With formaldehyde printing and dyeing assistant it is more be pure cotton textile, it is commercially available
" pure cotton is wrinkle resistant " clothes or wash-and-wear of shirt, all employ greatly the auxiliary agent containing formaldehyde, and formaldehyde may be discharged when wearing.In children's garment
Formaldehyde is essentially from the bonding kept used in the bright-coloured dyestuff attractive in appearance and Additives Products, and garment printing of children's garment color
Agent.Therefore, the rich and gaudy and stamp general content of formaldehyde of clothes is higher, and plain color clothes and without decalcomania children's garment content of formaldehyde then
It is relatively low.Formaldehyde, particularly garment for children can be all discharged in storage, wearing process for these clothes for containing formaldehyde and underwear is released
Harmfulness produced by the formaldehyde put is maximum.
Formaldehyde in indoor air has become the major pollutants of influence human body health.Particularly in the air in winter
Harm of the formaldehyde to human body is maximum.Formaldehyde source in family of China air mainly has the following aspects：（1）As indoor dress
The artificial boards such as glued board, core-board, medium density fibre board (MDF) and the particieboard of decorations.The adhesive that production wood-based plate is used is with first
Aldehyde is that formaldehyde remaining in main component, sheet material and having neither part nor lot in reaction gradually can discharge to surrounding environment, is to form Interior Space
The main body of formaldehyde in gas.（2）The furniture manufactured with wood-based plate.Some producers are for profit-push, using underproof sheet material, or
Person uses glue inferior, sheet material and the formaldehyde severe overweight in glue when being bonded surface lining.（3）Containing formaldehyde components and have
The other kinds ornament materials that may outwardly distribute, such as wall covering fabric, wallpaper, chemical fibre carpet, paint and coating.
The size of Formaldehyde Concentration of Indoor Air is relevant with following four factor：Indoor temperature, indoor relative humidity, interior
The loading degree of material（The formaldehyde emission material surface area of the i.e. every cubic metre interior space）, room air circulation.In high temperature, height
The dynamics of formaldehyde emission can be aggravated under wet, negative pressure and high load condition.Under normal circumstances the acquisition time of formaldehyde up to 3 ~ 10 years it
Long.
Formaldehyde is also from the other side of life.（1）Formaldehyde may be from cosmetics, cleaning agent, insecticide, disinfectant, anti-
Rotten agent, printing-ink, paper etc..（2）When foam lath makees house solar heat protection, resisting cold and insulating materials, in light with making under hot high temperature
Foam aging, rotten produce synthetic and release formaldehyde.（3）Hydro carbons can generate formaldehyde gas through photochemical conjunction, and organic matter is through biochemistry
Reaction can also generate formaldehyde, and substantial amounts of formaldehyde is also contained in burning waste gas, and such as often burning 1000L gasoline can generate 7kg formaldehyde
Gas, or even lighting cigarette also has 0.17mg formaldehyde gases to generate.（4）Formaldehyde is also from car seat support set, cushion and car
The upholstery finishing materials such as liner are pushed up, it is most prominent with new car burst size of methanal.（5）The formaldehyde also pollution from outdoor air,
Such as industrial waste gas, vehicle exhaust, photochemical fog can discharge or produce to a certain extent a certain amount of formaldehyde.
