How to remove formaldehyde quickly? What is the most effective method? What are the de-formaldehyde plants?

We all know that the newly decorated new house contains a large number of toxic substances-formaldehyde, can not be checked in immediately, so how to quickly remove formaldehyde? What is the most effective method? What are the de-formaldehyde plants?

I. the harm of formaldehyde

Can be sure to tell you that the so-called zero formaldehyde does not exist! It is just a publicity gimmick, unless all choose to decorate with solid wood, otherwise it will contain formaldehyde. Especially in summer, it is a common phenomenon that the formaldehyde of the decorated house exceeds the standard.

Although formaldehyde is an irritating gas, it is actually tasteless. As the most important and most grinding source of indoor pollution, it is not that it is toxic, but that it can be released continuously for a long time and slowly, with a release period as high as 3-15 years. And exceeding the standard by 2-3 times is usually impossible to smell! If you can smell it, it is seriously exceeding the standard! The harm of different concentrations of formaldehyde to the human body is also different, more than 6 times, it may lead to pulmonary edema, if it is up to 30 times, can immediately cause death!

I would like to persuade everyone here, Jane decoration! How ventilated! Pay more attention to choosing home decoration building materials and say no to formaldehyde from the source as much as possible!

Second, how to remove formaldehyde quickly and what is the most effective way to remove formaldehyde

1. The most effective and fastest way to remove formaldehyde is to open windows for ventilation!

Open the window ventilation to bring in the fresh air outside, the indoor formaldehyde concentration is diluted, the formaldehyde concentration is low, it is safe.

Formaldehyde has two characteristics: one is to accelerate the release rate at high temperature, and the other is soluble in water. The decomposition and emission of formaldehyde will be accelerated under the conditions of high temperature, high humidity and negative pressure. High temperature, such as summer or indoor air conditioning and heating; high humidity, turn on humidifier; negative pressure, in addition to window ventilation, you can spend about 300 yuan to buy an exhaust fan to draw air outside.

Some people have done a test in their new home, turn on the heat air conditioner, turn on the humidifier, use the exhaust fan of the air volume 520m3/h, 24 hours non-stop, ten days later, the formaldehyde concentration is reduced by half, and does not rebound. In fact, summer is a good season to remove formaldehyde.

two。 Install fresh air system

Tuhao's favorite way. Window ventilation is very suitable in summer, but in winter, it seems a little inappropriate. If the decoration budget is not tight, it would be better to spend 20,000 to 30,000 yuan to install a fresh air system, which can not only bring outdoor fresh air into the room, but also pass through pm2.5 filtration and heat exchange to ensure that the temperature in the house is not lost.

3. Air purifier (including activated carbon filter)

Originally, the air purifier is not aimed at formaldehyde, but formaldehyde pollution has been fired up in recent years. The activated carbon filter in the air purifier can physically adsorb formaldehyde, although the adsorption is less, but it is still effective. However, it should be noted that in order to prevent secondary pollution, the activated carbon filter should be replaced regularly, usually once every 7-8 months.

There are so many methods mentioned above, but I think the most effective way to decorate and remove formaldehyde is ventilation. If there is no condition to install the fresh air system, maybe you can try the method of indoor heating, humidification and exhaust. The budget is small and effective.

Third, the misunderstanding of removing formaldehyde (not recommended)

1. Adsorption of formaldehyde by bamboo charcoal, activated carbon and diatomite mud

Can you absorb it? Yes, but there are two conditions: one is the need for air flow to allow formaldehyde to come into contact with these adsorption carriers; the second is that the contact area should be large. But the problem with adsorption is that it will be released after saturation, that is to say, when these materials absorb enough formaldehyde, if the temperature rises, it will release the originally absorbed formaldehyde, resulting in secondary pollution.

two。 Green plants absorb formaldehyde

Some green plants have the function of absorbing formaldehyde, such as hanging orchids. Studies have shown that if the concentration of formaldehyde is 0.5 mg / m3 in a room with a height of 3 meters and 100 square meters, a hanging orchid needs to work for a year to absorb free formaldehyde. This is not the amount of continuous release of the plate. In other words, keeping dozens or hundreds of hanging orchids in your family may be a little useful in theory.

3. Decomposition of formaldehyde by photocatalyst

If adsorption is not good, then it is possible to decompose formaldehyde, right? Photocatalyst can decompose formaldehyde into water and carbon dioxide. Not to mention that this thing may have secondary pollution, and may not be able to buy the real thing, in addition, the removal of formaldehyde by light media requires a necessary environmental condition: ultraviolet light. However.

(1) the number of ultraviolet rays required by the photocatalyst cannot be satisfied by the ultraviolet rays in the sun, and the house needs to be covered with ultraviolet array lights.

(2) the formaldehyde that can be treated by photocatalyst is only the formaldehyde around it, and can not be dealt with beyond a few centimeters.

(3) photocatalyst particles are-10 power of PM2.5, which is a new air pollutant for home environment.

(4) at present, most of the domestic photocatalyst products can not remove formaldehyde for a long time, and can only be maintained for one or two months. Japanese photocatalyst is mainly used for the exterior walls of buildings, and is not used to remove formaldehyde indoors.

4. Products that remove formaldehyde

Now there are special formaldehyde removal products on the market, such as formaldehyde scavengers rely on chemical reactions to "remove" formaldehyde, the essence of this method is to oxidize formaldehyde into formic acid, but it is easy to decompose itself, spray on the board will damage the wood, and lose efficiency within a few hours, it is impossible to achieve "spray forever". Moreover, the high concentration of hydrogen peroxide sprayed in the air will cause new pollution hazards to people. Other oxidants and reducing agents can not effectively remove formaldehyde, and will introduce similar new pollution.

4. What are the green plants that remove formaldehyde

Although the effect of green plants absorbing formaldehyde is minimal, it can still play an important role in purifying the air and decorating the space. Here are some common green plants.

1. Green pineapple

As we all know, green pineapple is known as the "flower of life", which is an artifact to remove formaldehyde. It is not only easy to feed, but also brings environmental protection to human beings. The new home has just been decorated, the floor, walls will produce benzene, formaldehyde and other harmful substances, green apple adsorption capacity is super, play a role in purifying the air, a basin price of about 10 yuan, cost-effective and practical.

two。 Hanging orchid

The hanging orchid, known as the "king of formaldehyde removal", has strong photosynthesis at night and can absorb more than 80% of the indoor toxic gases. Placing a pot of hanging orchids in an 8-10-inch room is equivalent to an air purifier. And the decorative effect of the orchid is also very good, can be hung on the wall, does not take up space at all, kill two birds with one stone.

3. White palm

It may feel a little strange to hear the name, but it is more common in life. White palm belongs to hydroponic plants, which does not have high requirements for growth environment. The main function of white palm is to absorb the exhaust gas exhaled by the human body and formaldehyde emitted indoors. Don't underestimate this leaf, it's very effective.

4. Duck foot wood

Duck foot wood is the gospel of smoking families, can absorb the nicotine in the air, and then through their own transformation, the formation of non-toxic and harmless substances. There is always a pot of duck foot wood at home, which costs about 20 yuan, but it does no harm.

5. Tortoise back bamboo

The most obvious effect of tortoise back bamboo is that it can absorb carbon dioxide at night and then emit oxygen, giving people a comfortable sleep environment. Although in addition to formaldehyde can not compare with green pineapple, hanging orchid and other plants, but the ability to absorb carbon dioxide and improve the indoor environment can not be underestimated, it is very suitable to put a basin in the bedroom.

6. Rubber tree

The vitality of the rubber tree is very exuberant and its adaptability is super. Its greatest function is to absorb harmful substances such as dust and formaldehyde in the air. If the house is facing the street, the indoor dust will be a little more, you can put two pots of rubber trees to purify the indoor environment.
