How long does it take to dispose of formaldehyde, and how many days does it take to remove formaldeh

Under normal circumstances, after the house is renovated, if the state of ventilation is maintained every day, it will take more than three months to remove formaldehyde.

How long does it take for formaldehyde to be dissipated depends on the volatilization time of the specific release source. Generally speaking, trace amounts of formaldehyde can be dissipated in a few days, while high concentrations of formaldehyde can last for 3 to 15 years.

For example, it takes about 7 days for formaldehyde to be coated on the wall to volatilize, formaldehyde for wallpaper glue may take 18 months, the formaldehyde content in the large core board takes 15 months to 5 years, and the formaldehyde in the MDF takes more than 3 years or even more than 10 years. In addition, due to the interaction between formaldehyde emission and interior decoration bearing capacity, the more complex the decoration, the slower the formaldehyde volatilization.

At the same time, the release of formaldehyde is a continuous process, from thick to light, and the formaldehyde concentration can gradually decrease after a period of time. Therefore, it is advisable to use eco-friendly products when buying enough furniture, which will reduce a lot of pollution.

<> if it is a regular formaldehyde removal professional company construction, take a 100-square-meter house as an example, normal construction for two or three hours, after the construction is basically maintained for about a week. However, because the release period of formaldehyde is very long, about 3 to 15 years, even if it has been professionally removed, it is necessary to maintain the habit of opening windows for ventilation, so that even if harmful gases are generated, they will be discharged by indoor air convection.

For about a month, the question of new house occupancy cannot be answered by the concept of time.

Because the most important thing is to see if the air in the room is up to standard, if the air is up to standard, you can move in. If the new house has been empty for half a year after the renovation, but the air quality is still not up to standard, then it is still not allowed to live in. Therefore, after the decoration of the new house, we should try to find some ways to remove formaldehyde and other gases in the house, which generally needs to be vacant for about a month, and then the formaldehyde and other gas content can be tested, and the standard can be moved in.

Basically, the check-in time given by each formaldehyde removal company is different, ranging from 1 to 15 days.

If you buy a product from the Internet and manage it yourself, it is best to close the window for 2-3 days after using the product, and then open the window for ventilation for a day.

Before moving in, pay attention to close the window for a few hours to smell if there are any symptoms of physical discomfort after smelling, and do not rush to move in. It is best to check whether it exceeds the standard after treatment to ensure our physical and mental health.

After removing formaldehyde, you can move in about 3 to 5 months, and you should always keep the house ventilated, and you should also put some green plants at home, such as spider plant, tiger piran, which can effectively remove formaldehyde, and the residual plants are used as long-term green plants at home. And also put some activated carbon, which must be used for a long time, and it will also be good to adsorb and eliminate residual substances.

Formaldehyde treatment can be moved in immediately, but people who have experience in removing aldehyde know that the release life of formaldehyde is very long, and it cannot be completely removed in a short period of time.

1. Wise Stone.

It has regular honeycomb voids inside, its specific area is huge, can efficiently adsorb formaldehyde, its adsorption capacity is strong, can reach more than 20 times of the traditional activated carbon, not only the adsorption capacity is large, but also has the function of ion exchange, can decompose formaldehyde and other harmful substances into harmless carbon dioxide and water, without replacement can be used for a long time. When choosing, it is important to note that it is a gray ore with an irregular shape and is not a round particle

2. Open windows for ventilation.

This is nature's gift to us, and it is the most economical way to remove aldehyde, as long as you open the window, fresh air will enter the room, and formaldehyde will be purified by dilution.

3. 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.

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, high temperature.

The release rate of formaldehyde mainly depends on two factors, one is temperature, the other is humidity, so we can use this characteristic of formaldehyde, use heaters, humidifiers, etc. to keep the room in a state of high temperature and high humidity, and then we can cooperate with ventilation or adsorption materials to absorb the formaldehyde that has been released at home, this method is mainly to treat the latent formaldehyde in the home, and the effect is very good.

The formaldehyde concentration is lower than the national standard, and you can move in, and you can usually open the window for ventilation.

The volatilization time of formaldehyde is indeed relatively long, almost all need to wait for 4 to 5 years to completely volatilize clean, and the time for formaldehyde to be more serious may reach 10 years. However, as long as the indoor formaldehyde content reaches a specific standard, it will not cause harm to the human body, and it is relatively safe to live. After the home is decorated, you still need to pay special attention to the problem of formaldehyde, you should always pay attention to open the window for ventilation, and you can also install an air purifier indoors, which can circulate air and accelerate the volatilization of formaldehyde, and the volatilization speed of formaldehyde will become faster at high temperatures.

1.Plant absorption method.

Plants have a strong ability to absorb formaldehyde, such as cactus, spider plant, aloe vera, junzi orchid, iron tree, chrysanthemum, etc.

Many plants do have a purifying effect on the air, but they cannot completely remove formaldehyde, and can only play an auxiliary role.

2.Folk methods of spreading the soil.

Place tea pomace, grapefruit peel, onion slices, pineapple chunks, etc. in the newly renovated room or fumigate the whole room with white vinegar.

In fact, these local methods can only serve as a mask for odors. There is no way to remove formaldehyde at all. Not only is this undesirable approach. It is also likely to cause secondary pollution.

3.High-efficiency activated carbon adsorption method.

Solid activated carbon has the characteristics of many pores, and has a strong adsorption and decomposition effect on harmful substances such as formaldehyde, and the smaller the particles of activated carbon, the better the adsorption effect.

The adsorption effect of activated carbon on formaldehyde is obvious, and the amount of activated carbon placed varies according to the size of the space. In addition, activated carbon needs to be replaced after adsorption to a certain extent.

4.Chemical decontamination method.

It mainly consumes formaldehyde in the air through physical adsorption or chemical reactions. One is to purify the air by neutralizing formaldehyde and generating harmless substances; The other is to purify the air by sealing formaldehyde and preventing the volatilization of formaldehyde.

3-15 years. The time it takes to remove formaldehyde after renovation mostly depends on the environmental protection of the materials used in the renovation. If the material is natural and environmentally friendly, then formaldehyde can be removed as soon as possible; If the environmental protection of the material is low, then the formaldehyde release period will be correspondingly longer.

After the decoration is completed, you can use methods such as opening windows for ventilation, placing green plants, placing activated carbon or using air purifiers to reduce the formaldehyde concentration, and you can move in when the formaldehyde concentration returns to the normal range.

How to remove formaldehyde indoors?

1. Open windows for ventilation.

The easiest and most effective way to remove indoor formaldehyde is to open the window and let the gentle breeze blow into the closed room, so as to strengthen the air circulation, so that the indoor and outdoor air can be exchanged, the indoor turbidity is discharged, and the outdoor freshness is absorbed. As long as the anti-theft performance is guaranteed, the window needs to be opened for a period of time every day, if the formaldehyde pollution is not serious, the basic ventilation for 3-6 months, the formaldehyde concentration can be reduced back to the normal range.

2. Green plant absorption.

While opening windows for ventilation, you can also use other methods to help, such as placing greenery around the home. In fact, green plants have a certain aldehyde absorption effect, which can decompose formaldehyde molecules, so as to achieve the purpose of removing formaldehyde. Of course, although the effect of the green plant absorption method is still there, the ability is limited, and if the formaldehyde concentration is too high, the method may not be effective.

3. Put activated carbon.

In addition to placing green plants, you can also place activated carbon. Activated carbon aldehyde removal belongs to physical adsorption, because there are many small voids inside the activated carbon, which can intercept formaldehyde molecules in the air to remove formaldehyde. However, like the green planting method, the ability of activated carbon to absorb formaldehyde also has certain limitations, and the activated carbon package needs to be replaced regularly, otherwise it will lead to poor aldehyde removal effect, and may also lead to secondary pollution.
