How long does it take for indoor formaldehyde to evaporate?

Room pollution is mainly furniture, the highest concentration of formaldehyde pollution in summer, generally a few months after the decoration can only be moved into the newly renovated room, even if the ventilation for 2 months to half a year, the formaldehyde excess rate is still half. This is the result of the staff of the Liaoning Provincial Environmental Monitoring Center Station after monitoring the formaldehyde indicators of more than 60 households and workplaces.

Furniture is the main source of contamination in the living room.

Due to modern home decoration and furniture, formaldehyde is usually stored in the interlayer of wood-based panels as a raw material for binders, and it is extremely difficult to volatilize, and it usually takes 8 to 15 years to volatilize off. Zhang Zhuoqun, deputy director of the indoor monitoring room of the Shenyang Environmental Monitoring Center Station, said.

In fact, this kind of indoor pollution exists in almost every family, such as a bed, there is formaldehyde in the interlayer of the bed board, and this toxic gas will spread at night and become the main source of indoor pollution. Desks are a major source of pollution in the office, and when you use your computer, the rate of formaldehyde diffusion will increase as the temperature increases. These sources of pollution directly threaten the lives and health of every citizen.

Formaldehyde pollution concentrations are highest in summer.

A simple way to deal with formaldehyde is ventilation, but in the survey, the ventilation situation is very unsatisfactory. According to statistics, the ventilation time is shorter than the rate of pollutants in the house is high, the basic unventilated house throughout the year, the formaldehyde excess rate is as high as 80, the excess is serious, followed by the ventilation of two months to half a year of the house, the formaldehyde excess rate reaches 50, the ventilation of more than half a year of the house pollution is the lightest, the overall air quality is the best.

In summer, the pollution concentration of formaldehyde and ammonia is significantly higher than that in other seasons, which is undoubtedly caused by the diffusion of formaldehyde from wood-based panels due to evaporation.

The larger and more complex the decoration amount (even if the decoration materials of regular manufacturers are used), the more serious the exceedance, usually 3 5 times over-standard; The decoration is simple and the use of regular manufacturers of decoration materials at the same time is less polluting, usually exceeding the standard by 1 2 times. The report emphasizes.

Suitable for moving in after a few months of home renovation.

According to reports, the public should choose high-quality healthy and environmentally friendly building materials that meet national standards when decorating, and avoid using low-quality decoration materials. At the same time, it is not advisable to move in immediately after decoration, the windows should be opened every day for ventilation, and generally can only be moved in a few months after decoration, and ventilation should also be strengthened after moving in to minimize the degree of indoor pollution.

For indoors, especially in bedrooms, baby rooms, etc., some flowers and plants that adsorb formaldehyde should be raised, which can also reduce pollution. Citizens with conditions can also buy air purification devices for treatment, but they should be used carefully to prevent secondary pollution.

Generally, after decoration, it is necessary to ventilate for at least half a year before you can move in, and you have to ventilate for a while before you can move in if you have a baby at home. According to my understanding, I will introduce several easy-to-use methods to remove formaldehyde, so that you can live in two weeks:

1. Plant absorption method: Experiments have proved that the effect of plants in removing formaldehyde is relatively weak, but it still has a certain effect, at least it can release more oxygen in the sun, making the family's life easier and more pleasant.

2. Photocatalyst: The photocatalyst can decompose harmful organic compounds such as formaldehyde, toluene, and TVOC under the action of light, and the stronger the light, the better the effect. Photocatalyst wood essential oil can be sprayed directly on the furniture floor, and the photocatalyst has no secondary pollution.

3. Physical adsorption method: Some materials have the characteristics of porous structure, such as Mayan blue and activated carbon, these tiny pores can contain formaldehyde, toluene and other harmful gas molecules, so they are good formaldehyde removal materials.

After the renovation of a new house, it generally takes about 3-6 months to be clean. General formaldehyde refers to the free state and the polymerized state. If it is formaldehyde in the polymerized state, it will take longer, the indoor temperature is different, the ventilation time of each room is different, and the time of formaldehyde emission will cause different results.

It is best to put more plants that can remove formaldehyde indoors to help the kitchen purify the formaldehyde components in the air.

This is not necessarily true.

Because the formaldehyde content of different materials is very different, some are even rare, and it depends on whether it is ventilated, and the ventilation situation and time.

Of course, there are also measures to remove formaldehyde.

Generally, it takes about 2 months to move in.

Reduce the harm of indoor formaldehyde (about a month or so) ventilation method to remove formaldehyde.

The best way to do this is to ventilate, which is the simplest, most economical and most effective method.

Green plant absorption method to remove the hazards of formaldehyde.

Plants have a strong ability to absorb formaldehyde, such as cacti, spider plant, reed, ivy, iron tree, chrysanthemum, etc. Generally speaking, plants with large foliage and vanilla absorb formaldehyde well, such as spider plant, tiger tail orchid, etc.

Photocatalyst decomposition formaldehyde method.

Qingmanluyou nano photocatalyst can be said to be the natural enemy of formaldehyde, which has a strong decomposition effect on harmful substances such as formaldehyde, generally sprayed for about a week, formaldehyde will be reduced to a safe range, and the newly released formaldehyde in the later stage also has a long-term effect.

Vegetable and fruit absorption reduces the harm of formaldehyde.

You can put the grapefruit peel, onion slices, pineapple pieces, etc. at home in the newly renovated room or cabinet, or fumigate the whole room with white vinegar.

The release life of formaldehyde will be as long as more than ten years, especially the inferior decoration materials, the removal of formaldehyde has a long way to go, do not listen to rumors, the following is for you to introduce several methods of removing aldehyde, so that you can control formaldehyde in a safe range as soon as possible.

1. Open window ventilation is currently a more reliable method of removing formaldehyde, simple and convenient to use, as long as the window is opened, there will be a steady stream of air pouring into the room, and the indoor air containing formaldehyde will be discharged to the outdoors, but due to weather reasons, opening the window to remove aldehyde will have certain drawbacks when it is windy and rainy, so open the window ventilation must be optimistic about the weather forecast!

4. Choose plants that can adsorb formaldehyde, pothos, aloe vera, spider plant and other plants can adsorb certain formaldehyde pollution, and can indeed remove formaldehyde. Placing some greenery in your new home can also help to beautify the room and freshen the air. However, the adsorption capacity of plants is relatively limited, and if the formaldehyde concentration is too high, the plants will wilt and die.

5. If you want to eliminate formaldehyde in the house as soon as possible, you can put a floor fan at home after the decoration is completed, and open the window for ventilation at the same time.

6. In the case of high temperature, it can promote the conversion of formaldehyde in the bound state into free formaldehyde and reduce the total content of formaldehyde, because formaldehyde penetrates deep into the inside of the plate, although the formaldehyde cannot be completely removed, but the effect is still very obvious

Indoor formaldehyde release sources do not exist in isolation, and their formaldehyde content is the accumulation of the amount of release from various release sources.

According to the different release sources, its volatilization time is not the same, formaldehyde in wall paint can be volatilized in 7-15 days, formaldehyde in wallpaper glue for more than 18 months, formaldehyde in large core boards for 15 months to 5 years, and formaldehyde in MDF veneers are almost all more than 3 years or even more than 10 years. Formaldehyde in flooring has a longer evaporation period than MDF.

You have to open the windows often to ventilate, don't think about it overnight.

Summary. In summer, formaldehyde will volatilize in about 2 months, and it will volatilize faster. Due to the climate characteristics of high temperature and high humidity in summer, formaldehyde volatilization is extremely serious.

In different seasons of the year, formaldehyde emissions vary greatly. The excess rate of formaldehyde in winter is 20%, the excess rate of formaldehyde in spring is 36%, the excess rate of formaldehyde in autumn is 70%, and the excess rate of formaldehyde in summer. The "superposition effect" of indoor pollutants makes beds, wardrobes, floors and other panel furniture become the main sources of formaldehyde release.

The harm of formaldehyde does not need to be repeated, such as allergic dermatitis, fatigue, insomnia, headache, mucosal congestion, and life-threatening nervous disorders.

The harm of formaldehyde does not need to be repeated, such as atopic dermatitis, fatigue, insomnia, headache, mucosal congestion, and nervous disorders.

Can I use the stuffy method to remove potassium aldehyde in summer? Can I quickly remove potash aldehyde when it is turned off during the day and turned on at night?

OK. How long can I stay with a three-month-old baby?

What a house.

Last 3 months.

The main cabinet of 116 square meters is made of MDF that is not environmentally friendly, has no environmental protection grade, and does not have a brand of MDF as a wardrobe?

Leave for 3 months. Then buy a few pots of spider plants and pothos to put away.

Then buy a few pots of spider plants and pothos to put away.

Can I stay with peace of mind for 3 months? MDF is not edged and is it burred?

OK. years? Can I stay with peace of mind for 3 months?

OK. Doesn't it say that potassium aldehydes are released for 3-15 years? Can I stay with peace of mind for a short period of 3 months?

Why do you still buy a new house for decoration in 3-15 years?

Don't believe what others say.

Put it for 3-15 years, then you can simply live in a second-hand house.

Don't buy a new home.

Usually seven to eight hours.

Let me start by saying that in a high temperature and high humidity environment, formaldehyde can accelerate the release rate, that is to say, the air conditioner is heated at 30 degrees for 7-8 hours, and the amount of formaldehyde released at this time is n times that before the air conditioner is turned on. Moreover, when I searched a large number of literature on formaldehyde removal before, I saw such a conclusion: high temperature and high humidity environment can promote the release of formaldehyde from indoor floors.

For example: 1. At normal temperature, the total amount of formaldehyde in the room is 100, after 7-8 hours, formaldehyde releases 30, and then we ventilate or use other methods to remove formaldehyde, up to 30 formaldehyde can be removed, and there is 70 formaldehyde left in the room;

2. In the room that lasts for 7-8 hours of high temperature, the total amount of formaldehyde is still 100, but the amount of formaldehyde released at this time is as high as 80, and then we can ventilate or use other methods to remove aldehyde at most, at most 80 formaldehyde can be removed, and the amount of formaldehyde left in the room is 20;

Tongfeng is wide compared with the data, and the results are clear at a glance. If the air conditioner is turned on at 30 degrees Celsius for 7-8 hours, and then ventilated, the formaldehyde will go faster than before!!

But this method also has certain drawbacks, that is, once the temperature drops, the speed of formaldehyde release will be slowed down immediately, very inconvenient, for lazy people like me, it is best not to worry about themselves, and 24 hours uninterrupted formaldehyde removal, I can rest assured.

Formaldehyde removal machine.

1. Air Evolutionary.

Principle: The fan rotates, which can actively adsorb formaldehyde and reduce the indoor formaldehyde content.

Advantages: Digestion is more obvious.

Disadvantages: It consumes a little bit of electricity, and the purifier filter needs to be replaced regularly.

**: 2000-10,000 more.

Enjoy fresh air in 3 minutes, with high filtration efficiency.

For new house decoration, the particle purification efficiency is greater than or equal to 99%.

2. Find a professional organization to provide door-to-door service, and try to find a big company and a big brand.

Advantages: safe and credible, reliable, one-stop service and trouble-free.

Disadvantages: Relatively high cost.

Small area housing within 50 square meters, recommended.

Large area, 260-269 sq. m., recommended.

Summary: The above methods are more suitable for lazy people, Lao Jixiang is like myself, but ** will be a little expensive. It is more suitable for a new house, after all, the new home is worth taking care of.

According to the different release sources, its volatilization time is not the same, formaldehyde in wall paint can be volatilized in 7-15 days, formaldehyde in wallpaper glue for more than 18 months, formaldehyde in the large core board for 15 months, and the best way to deal with it is ventilation. Or buy some plants to absorb formaldehyde, generally speaking, large foliage and vanilla plants absorb formaldehyde better, such as spider plant, tiger tail orchid, etc.
