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

After the decoration of the treasure interior, it takes about three months to remove the formaldehyde in the room.

1. Ventilation. This is the most natural and commonly used method, and the effect is also relatively good, only need to open the window.

Second, put plants. You can use some small bonsai that can absorb toxic gases, like pothos, etc.

3. Put bamboo charcoal. Because the main component of bamboo charcoal is activated carbon, and activated carbon can effectively adsorb toxic and harmful gases and dust in the air due to its porous characteristics.

Fourth, formaldehyde removal purifier. In addition to formaldehyde, the air purifier purifies bacteria and odors, pollutants in new house decoration, formaldehyde, TVOC, stupid, and other air harmful substances at the same time, so that you can easily enjoy a healthy breathing environment all year round.

After a month, you can.

Formaldehyde can be removed in three yearsIt takes about three years to remove formaldehyde for decoration. In home decoration, a lot of formaldehyde will be volatilized, such as wall painting, floor laying and furniture, will contain a large amount of formaldehyde. Therefore, it is not possible to move in immediately after the decoration of the new house, and it takes at least three months of ventilation to reduce the concentration of indoor formaldehyde significantly, which will not pose a threat to human health, but it takes a long time to remove formaldehyde, because with the passage of time, the volatilization rate of formaldehyde will become slower and slower, and it will take about three years to completely remove it.

<> 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.

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.
