How to remove formaldehyde after home decoration?

1. After the decoration, our home will inevitably produce some pungent odors, most of these smells are harmful to our body, most people will choose to open the window to ventilate to let these smells dissipate, but is the window ventilation really effective? Sometimes it makes the smell go down slightly, but sometimes it's the smell that becomes more complicated.

2. There are some ways to open windows for ventilation in the renovated house. When the renovation is just completed, never open all the windows, and choose to open the windows for ventilation. It can be half-open, up-open or down-open, etc.

If you open it all, it will cause some harm to the newly renovated house. After two weeks, it will be fully ventilated.

3. Open the window for ventilation.

Opening windows for ventilation can make indoor air circulate better, thereby reducing the concentration of toxic gases in the room. But opening windows for ventilation does not solve this problem at the source. In a poorly ventilated room, the formaldehyde concentration still does not decrease.

In the case of bad weather, it is useless to open the windows for ventilation. And now the outdoor air pollution is also more serious, the outdoor is also relatively high, and the ventilation of the window can achieve the desired effect. The window cannot be opened at any time, so the ventilation of the window cannot solve all the problems in the room.

4. With activated carbon, we all know that activated carbon has a certain adsorption effect, which can adsorb harmful substances in the air. So put some activated charcoal in the corner of the house to achieve the effect of purifying the air. However, this one cannot be used for a long time and needs to be replaced frequently.

5；Does green plants absorb formaldehyde?

Everyone knows that green plants have the effect of evolving the air, so you can buy some green plants and put them at home to purify the air.

For example: tiger tail orchid.

Saxivia has a good effect on purifying the air. Studies have shown that Saxivia can absorb some harmful gases in the room, such as sulfur dioxide, chlorine, ether, ethylene, carbon monoxide, nitrogen peroxide and other harmful substances.

Saxivie is a bedroom plant and is best used in the bedroom. Even at night, it absorbs carbon dioxide and releases oxygen. According to relevant studies, six waist-high tiger orchids can meet the oxygen intake of a person.

The use of coconut charcoal in indoor cultivation of tiger tail orchid can not only improve people's work efficiency, but also reduce the need to open windows for ventilation in summer.

Rose. It is a very common flower, this flower is an expert in absorbing harmful gases, not only can absorb harmful gases such as hydrogen sulfide, hydrogen fluoride, benzene, phenol, etc., but also can have strong resistance to sulfur dioxide, nitrogen dioxide, etc.

1. Open window ventilation: window ventilation is the simplest and most direct way to remove formaldehyde, but removing formaldehyde is a long-term work, and the effect of window ventilation is slow, so it can only be used as an auxiliary method.

2. Activated carbon adsorption: Activated carbon is cheap, simple and practical, and harmless to the human body. There are many small pores and crevices, relying on this physical adsorption of formaldehyde method has a certain effect, but after 1 month the activated carbon is saturated, the adsorption effect will disappear, and the activated carbon will emit a part of the harmful gas that has been adsorbed after the adsorption saturation, which needs to be replaced regularly.

3. Green plant purification: spider plant, tiger tail orchid, pothos and other plants can purify the air through photosynthesis, and also purify some formaldehyde gas. However, the adsorption capacity of plants is limited, and photosynthesis has no effect at night.

4. Air purifier: The air purifier can remove a certain amount of formaldehyde within a certain period of time, but formaldehyde exists in decoration materials and is continuously released, so this method treats the symptoms but not the root cause.

5. Install MIA fresh air system: the fresh air system sends the outdoor fresh air to the room through the fresh air supply device after filtering it through the fresh fan, the outside air has high oxygen content, but there are also many harmful gases and germs, and the filtration system of the fresh air fan can effectively intercept these harmful gases, which not only ensures that the indoor oxygen is sufficient, but also ensures the cleanliness and safety of the indoor air.

In addition to formaldehyde, we must first understand the ** of harmful gases such as formaldehyde.

Mainly a variety of decoration materials, in order to improve his performance, such as color fixing, anti-corrosion, etc., will add a lot of chemical components. For example, formaldehyde is added to the glue to increase viscosity, and benzene is added to the latex paint to prevent cracking after painting. Even if it is solid wood, it needs to be preserved, otherwise it will be mothed in a few years after selling it back, and it will definitely not work.

Now the vast majority of furniture is made of wood chips bonded to the city's MDF, particleboard, etc., and the surface is pasted with a layer of film, so that formaldehyde exists in a large number of boards, and because the outer layer is wrapped, the release is hindered, so that the formaldehyde release time is as long as 3-15 years. If you want to remove it quickly, you have to accelerate the release of formaldehyde in the board, for example, if you don't decorate it first, put the board at a high temperature to accelerate the release, and release it for several months, but it may damage the performance or appearance of the board.

Current formaldehyde removal methods and effects:

Ventilation and drying: It seems that the most economical method is that most people think that it will be about the same for half a year at most, but in fact, due to the above-mentioned characteristics of the board (wrapped in beautification film), it must be dried for at least 3 years to basically reach the safety level. The time and labor costs are still very high.

Activated carbon: Activated carbon is the most commonly used method, although it can adsorb, but it likes to adsorb water molecules the most. If activated carbon is ventilated and dried, most of the water is adsorbed, and it may reach saturation in 1 week.

Either replace it with a new one, or dry the activated charcoal and continue to use it. If the time is too long, activated carbon guarantees harmful substances, then it is a source of poison!

Green plants: For green plants, formaldehyde is also harmful to it, and it is not comfortable to suck too much, but it has no way not to suck it. If you really want to rely on green plants, then you need to have dense greenery like a rainforest at home. Several pots of green plants have limited adsorption.

White vinegar, water, etc.:

For formaldehyde in the air, there is a certain removal effect, because formaldehyde is easily soluble in water, and the acidity of vinegar does not have a good removal effect on formaldehyde, more is the absorption of water. But after all, it was just an absorption, and it didn't stop the release, and a simple single basin of water didn't have much effect.

Heating and ventilation: Heating up can indeed speed up formaldehyde emission. But how?

Summer may be good, all above 30 degrees, but on the shady side, the corners and the back of the cabinet where the sun does not shine, in fact, the temperature is not particularly high, and the emission effect is poor. In spring and autumn, if the temperature increases, you need to turn on the air conditioner, and you have to close the window to open the air conditioner, so as to achieve no dead angle heating, but close the window to obstruct air circulation, then when the formaldehyde is released, the higher the indoor formaldehyde concentration, the slower the emission will be, and you have to open the window regularly to close the air conditioning for ventilation. In this way, the temperature and emission of formaldehyde may last for half a year, and the formaldehyde at home can be almost dispersed, so in fact, the cost of manpower and time is very high.

Biological enzymes, photocatalysts, etc.:

This is the principle of formaldehyde treatment, biological enzymes are enzyme decomposition, and most of the photocatalysts are titanium dioxide catalytic, sprayed on the surface of furniture to decompose harmful gases such as formaldehyde. The more long-term effect is the photocatalyst, because it is titanium dioxide that will not degrade, and the aging of decomposition of formaldehyde is long, while biological enzymes will be affected by temperature and humidity and lose their activity because they are enzymes.

Formaldehyde in new houses is generally divided into two types, one is free formaldehyde in the air, and the other is formaldehyde that has not been released in the furniture. So most methods just remove free formaldehyde from the air, such as ventilation. The formaldehyde in the plate that has not yet been released will be continuously released into the air with the change of temperature.

One: reduce formaldehyde at the sourceThis is to start from the root and try to use environmentally friendly wood, that is, pure solid wood furniture products. If it is a new house that has been renovated, then this step can be ignored and look directly below.

2. Decomposition and release of formaldehydeBaizao Na adds two-component decomposition components, which can automatically adsorb and decompose harmful gases such as formaldehyde, and is sun-free for three years, which is very suitable for people who are in a hurry and have large pollution.

Three: Wipe down the furniture regularlyFormaldehyde is soluble in water, and furniture is an important part of household pollution, after moving in, regularly wipe the surface of furniture with water, can effectively take away the toxic and harmful substances attached to the surface of furniture, and can play a good preventive role in reducing the release of pollutants.

After decoration, the formaldehyde in the house is volatilized from the decoration materials. The most serious are sponges and synthetic artificial boards. The volatilization of this formaldehyde is a very slow process.

No matter what method you use to remove formaldehyde, it is useless. It can only be slowly cleared up over time. So the only correct way is to leave it vacant for half a year to a year after renovation, and let him volatilize by himself.

Don't trust the company's methods of removing formaldehyde. It's all just a gimmick.
