How long does it take for formaldehyde to run out? Looking for an extension of environmental protect

At least 3 months, and it is summer, the weather is cold and slow, formaldehyde volatilization is more than 30 degrees to be efficient, as for three days to stay is blind, 30 days can not be dispersed!

Generally, you need to wait for three to five months before you can move in, if you want to remove it quickly, it is recommended that you can use Moqing stone to absorb and decompose, this is not saturated, and can be used for a long time.

How long does it take for formaldehyde to run out? How long does it take for a new home to move in?

In response to this problem, we have done a number of tracking tests, for ordinary new houses, after the decoration of 2-3 times more than the standard is a relatively normal phenomenon, decoration materials to choose environmentally friendly pollution will be lower, but it is still difficult to achieve the standard, if only open the window ventilation, without doing any other formaldehyde treatment, our test data show that the minimum need to dry the room for 6 months, and it is best to go through the summer, or the time to dry the room needs to be delayed to 6-9 months.

After the new house is ventilated and dried for a period of time, as long as the time is enough, it can still meet the check-in standard, but it does not mean that the formaldehyde at home will no longer be released, the release cycle of formaldehyde is as long as 3-15 years, and the release amount in the early stage is large, but the later stage is also in the continuous release, so we should also pay attention to continue to maintain good ventilation after moving in, so as not to exceed the standard due to formaldehyde accumulation.

What formaldehyde removal methods really work?

1. Ventilation

There is no need to talk about this, the people of the earth should know that the first thing after the decoration is to open the window for ventilation, so that the internal and external air convection is up, to avoid indoor pollution accumulation leading to excessive pollution, for poor ventilation of the house or room can use a fan to accelerate the convection, which can also play a good role in ventilation.

2. Green plants

After the decoration at home to put a few pots of green plants can not only purify the air, but also play a role in decorating the indoor space, can purify the air of the plants are: pothos, spider plant, tiger orchid and yew, etc., the appropriate amount of choice to put some in the new house can also play an auxiliary purification role.

3. Decomposition of algae

Baizao Na is a purification material more respected by environmental protection engineers, its adsorption and purification speed is dozens of times that of activated carbon, and the key is that it can decompose formaldehyde, does not need to be dried, and does not have to worry about adsorption saturation.

4. Wipe with salt water

Furniture is an important part of the odor and pollution at home, the harmful gases in the furniture board will be released into the indoor air through the surface of the board, wiping the furniture with mild salt water can take away some of the harmful substances attached to the surface of the furniture, which is helpful to accelerate the removal of furniture odor, and regular wiping can also play a good role in accelerating purification.

At present, the more authoritative answer is 3-15 years, and if you subdivide it, you need to first understand that the formaldehyde we generally refer to refers to the free state and the polymerized state. Among them, formaldehyde in the free state can generally be volatilized within 2 months; Formaldehyde in the polymerization state is difficult, and different places, different indoor temperatures, and different ventilation conditions will cause different results. However, polymerized formaldehyde needs to be converted into formaldehyde in a free state first, and then volatilized is common.

If you want to release formaldehyde cleanly, it can take a long time, it may take 3 to 15 years, so the natural release is not reliable, at present, it is more reliable to stabilize the concentration of formaldehyde within a safe range, and the following recommends several easy-to-use methods for everyone.

1. Wise Stone.

It can actively adsorb indoor free formaldehyde, the process will not be affected by any external factors such as temperature, humidity, light, etc., the adsorption rate of formaldehyde is also dozens of times that of ordinary adsorption materials, in addition to the unique decomposition function, the adsorbed formaldehyde can be decomposed into harmless carbon dioxide and water, and then discharged, so that its internal pores have been in an unsaturated state, and the aldehyde removal rate can reach more than 90%. When choosing, it is important to note that it is a gray ore with an irregular shape and is not a round particle.

2. Plants.

Plants such as aloe vera, cactus, and pothos have a certain ability to absorb formaldehyde, and can slowly consume the surrounding formaldehyde through photosynthesis. Because it is a plant, it is very safe and does not produce other harmful effects. However, it should be noted that the absorption of formaldehyde by plants is limited and can only be used as one of the comprehensive treatment methods to remove formaldehyde

3. Open windows for ventilation.

If you want to remove formaldehyde and odor as soon as possible, the first thing to do is to open the window for ventilation, open the cabinet doors and drawers at the same time, and dilute and discharge the formaldehyde to the outside through air convection. Although this step is simple, it is also necessary to pay attention to the weather conditions, so as not to break the newly renovated home environment with strong wind and rain.

4. Formaldehyde remover.

Under certain conditions, formaldehyde scavengers react chemically with formaldehyde to produce other substances that are not harmful to health, so as to reduce the concentration of formaldehyde in the room. But it's also a chemical in its own right, and if used incorrectly, it can be another source of pollution indoors.

Fifth, the fresh air system.

The fresh air system is a system that filters the outdoor air and transports it to the room through the pipeline, and discharges the harmful substances contained in the room from the corresponding pipeline.

In order to better reduce the formaldehyde concentration in the home environment, in the process of decorating the new house, try to control the quality of decoration materials and choose materials with relatively low formaldehyde content.

If it is just ventilation, it generally takes 7 to 10 years, of course, you can't move in directly, the formaldehyde content of the newly renovated house must be very high, which will cause unimaginable consequences to the human body, we can use some products to speed up the removal of formaldehyde. I have used Dialin before, and the effect is not bad, so I recommend you to use it; After that, some Ye Guangni was also placed in various corners of the room to continue to absorb and decompose, so that the formaldehyde disappeared more completely.

There are many ways to remove formaldehyde, but the release life of formaldehyde is very long, and it is difficult to remove it completely in a short time, so how can we remove formaldehyde quickly? Recommend several useful methods to everyone.

1. Open windows for ventilation.

Open the window ventilation is the best way to remove free formaldehyde, when the window is opened, there will be a steady stream of fresh air will dilute the indoor air containing formaldehyde to achieve the purpose of purifying formaldehyde, but the window is easily affected by the weather, and the effect is also affected by the house type when used.

2. Increase the temperature.

We all know that formaldehyde is volatile at high temperature, and we can use some heating equipment to increase the temperature at home a lot, so that a large amount of formaldehyde gas can be volatilized, and then formaldehyde can be removed by opening windows for ventilation. Repeated operation a few times, you can remove most of the formaldehyde in the home, but we must pay attention to safety when using heating equipment to avoid fire.

3. Ruishi. Ruishi is currently a popular aldehyde removal product, it is a pure natural ore, in which it has a large number of rules, and the size of formaldehyde similar pores, its adsorption capacity is more than 20 times that of activated carbon, and at the same time has an ion exchange function, can decompose the adsorbed formaldehyde, so that a purchase is effective for a long time.

4. Plants. Putting some green plants at home can also effectively remove odors, especially pothos, spider plants, aloe vera, monstera, cactus, ivy, etc., which can effectively absorb harmful gases. In addition, large plants such as the Ping An tree and the camphor tree, which are more popular on the market, can release a fresh gas on their own, which makes people feel happy, and is also more suitable for removing the smell of new furniture.

5. Fresh air system.

The fresh air system can introduce fresh air outside and discharge harmful substances from the indoor space through the system's filtration device during the period when the windows cannot be opened, which will reduce the concentration of free organic pollutants in the indoor space to a certain extent and speed up the release of pollutants. Through continuous circulation, the indoor decoration pollution is controlled.

In summer, formaldehyde takes at least three or four months to volatilize. The volatilization of formaldehyde is a continuous process, even if it is half a year, this kind of thing cannot be completely volatilized, but the concentration will be reduced to a level acceptable to the human body.

Formaldehyde generally volatilizes faster in summer, and the volatility of formaldehyde increases as the temperature increases. Generally, the volatilization period of formaldehyde is as long as 3-15 years, and there are many ways to remove formaldehyde, such as activated carbon, green plants, etc., but the best way is to open windows for ventilation.

Generally speaking, when buying environmentally friendly furniture and paint, the harm of formaldehyde is much smaller at this time, because the formaldehyde concentration of this furniture is within the acceptable range of the human body.

If the newly renovated house, you can open the window for ventilation for two months, ventilation is indeed the best way to remove formaldehyde, but the volatilization period of formaldehyde is 3-15 years, although ventilation for 2 months can reduce some formaldehyde concentration, but can not effectively remove formaldehyde.

It is also a good way to use orange peel, grapefruit peel is used to remove odors, but the formaldehyde concentration does not decrease, it just does not smell.

In addition, you can store some pothos at home, etc., which can make the smell of formaldehyde more easily dissipated.

How long does it take for formaldehyde to completely dissipate when a new house is renovated? Keep these 5 points in mind to let formaldehyde be released quickly.

The best way to remove formaldehyde is ventilation. The volatilization period of formaldehyde is generally as long as more than 15 years, no matter what method you use, you can't use it continuously for more than 15 years. Of course, in winter (north) and due to weather and other reasons can not open the window ventilation, in addition to formaldehyde is the most commonly used effective way is to directly find a professional company for testing and treatment, our family is looking for Shanghai Limao environmental protection, after the end of the treatment of formaldehyde detection does not exceed the standard can be safe to move in.

How long does it take for formaldehyde to disperse in a newly installed house; After the renovation of the new house, it takes 3-6 months to be ventilated and vacant for 3-6 months to reach 95% dispersion. . .

At the very least, it will take 1 year, two years, or even longer to cut the bottom and disperse. But as long as it meets the national allowable concentration standard for formaldehyde (about it), you can move in.

According to China's housing air standard, the maximum allowable concentration of formaldehyde is (0 08mg m3).

The newly renovated house takes a period of formaldehyde to disperse, and it takes at least two or three months to ventilate the formaldehyde, but there will still be formaldehyde hazards that are not comprehensive enough, the following is my experience in removing formaldehyde:

1. First of all, it is necessary to give it a lot of basic furniture to pass through the wind, and the door should also be opened to disperse the wind, and it cannot be closed.

2. You can put some Yeguang mud activated carbon in the corners and furniture of the house to adsorb formaldehyde.

3. Put some plants such as cactus, pothos, etc.

After the decoration of the new house, the free formaldehyde in the air is easy to remove, and it only takes one or two months to open the windows for ventilation after the decoration; The formaldehyde enclosed in the decoration materials will be slowly released into the air, and this process can take up to several years.

The pollution sources of formaldehyde enclosed in decorative materials for new house decoration mainly exist in: floor leather, plastic veneer, plywood (including large core board, solid wood multi-layer board, particle board, etc.), wallpaper, latex paint, good or synthetic fibers and adhesives.
