How to deal with formaldehyde after the decoration is completed?

Formaldehyde after decoration mainly comes from the following three aspects: Formaldehyde in man-made boards such as plywood, blockboard, MDF and particleboard used for interior decoration. The adhesive used in the production of wood-based panels takes formaldehyde as the main component, and the residual and uninvolved formaldehyde in the board will be gradually released to the surrounding environment, which is the main body of formaldehyde in the indoor air.

Formaldehyde in furniture made from wood-based panels. In order to pursue profits, some manufacturers use substandard boards, or use inferior glue when bonding veneer materials, and the formaldehyde in the boards and glues seriously exceeds the standard.

Other types of decorative materials that contain formaldehyde and will be emitted to the outside world, such as wall coverings, wallpaper, chemical fiber carpets, paints and coatings, etc.

1. Open window ventilation method. This method will not be explained much, this must be carried out, but it is not enough to just open the window for ventilation, it also needs to be combined with other methods!

Second, the water absorption method, in the renovated new house put a few basins of water, the water into the orange peel, green onions, vinegar, etc. can be evaporated to protect the top of the wall paint surface, but also can absorb the indoor odor. It is enough to change the water 2 times a day.

3. Plant purification method. Many families, banks, companies, etc. have placed plants, the most common are spider plant, aloe vera, cactus, etc., such as cactus, which can not only prevent radiation, but also beautiful, and most importantly, can purify the air, so it is loved by many office workers.

Fourth, professional removal method. The role of the above three points is not very large, if the air exceeds the standard, it is to find a professional to test first, and after the test, it will be treated according to the actual situation.

It is not right to just remove formaldehyde, because new houses not only contain formaldehyde, but also harmful gases such as benzene. Different plants absorb different gases, such as:1

Plants that have the effect of absorbing formaldehyde, such as aloe vera, spider plant, agave, etc.; 2.Plants that have the effect of absorbing benzene, such as ivy, iron tree, etc.; 3.Plants that have the effect of absorbing trichloroethylene, such as evergreen, agave, daisy, etc.; 4.

Plants that have the effect of absorbing sulfur dioxide, such as moon, rose, etc.; 5.plants that have a vacuuming effect, such as osmanthus; 6.Plants with bactericidal properties, such as mint.

Formaldehyde can be removed by plant extraction of photophyll and photocatalyst, aldehyde removal enzyme and so on. At the same time, multiple methods can also be taken to remove formaldehyde.

1.Buy some activated carbon balcoidite packs, which have 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.

2.You can buy an air purifier, and the air purifiers mainly include negative ion type, ozone type, filter adsorption type, electrostatic integration type and photocatalyst type. It can be selected according to needs to achieve the purpose of indoor air purification.

Of course, it is also possible to use some auxiliary methods at the same time. For example, the use of plants through photosynthesis to absorb and decompose formaldehyde and other harmful gases, play a role in purifying the air, more effective plants are monstera, pothos, pineapple, tiger orchid, orchid and so on. Hope it helps.

The methods of removing formaldehyde after decorating the house are: opening windows for ventilation, high temperature, activated carbon, green plants, black tea, etc.

1. Open windows for ventilation

After many people's new homes are renovated, they will open the doors and windows to ventilate. This is because formaldehyde, benzene and other harmful gases are volatile, open the doors and windows can allow indoor formaldehyde and other harmful substances to be discharged, if in the case of high temperatures, the release of formaldehyde will be relatively large.

However, due to the release cycle of formaldehyde as long as 3-15 years, simple ventilation can not solve the problem of formaldehyde pollution from the book, and this method should pay attention to closing doors and windows at night to avoid theft.

2. High temperature is conducive to formaldehyde release

It is worth noting that formaldehyde is a very slow volatile gas, if you want to increase the amount of formaldehyde released in a short period of time, the best way is to try to turn up the indoor temperature, you can turn on the air conditioner for an appropriate amount of time to raise the indoor temperature to speed up the volatilization of formaldehyde.

3. Activated carbon and other physical adsorption methods

If you want to remove formaldehyde quickly, you can also take the physical adsorption method, for example, put more activated carbon indoors, it is recommended to place about 50g of activated carbon per square meter can have a good adsorption effect on formaldehyde. It is worth noting that attention should be paid to the replacement of activated carbon, which is generally appropriate once every 7-8 months.

4. Green plants

In addition, you can also plant some flowers and plants indoors, which can not only play the role of greening the new home, but also play a role in removing formaldehyde. According to scientific experiments, many green plants such as spider plant, cactus, tiger tail orchid, iron tree, chrysanthemum, etc. have a certain absorption capacity for formaldehyde.

However, the adsorption effect of plants is limited, and some plants are not suitable for large quantities in a room. Therefore, it is unrealistic to completely rely on the adsorption function of plants to solve the problem of decoration pollution.

5. Black tea

Black tea is a good helper to remove formaldehyde, put black tea into a basin full of boiling water, and then place it around the bedroom and window for a week, basically can alleviate some of the pungent smell of formaldehyde, insist on use, and bring us fresher indoor air.

1. Open windows for ventilation, often open windows for ventilation, can effectively improve indoor air quality and effectively discharge harmful gases. The disadvantage is that it is more susceptible to weather and season.

2. Plant adsorption, in an environment where indoor environmental pollution is not serious, you can breed more plants, plants have the function of adsorbing formaldehyde, and many plants can also adsorb formaldehyde, benzene and other harmful substances. The disadvantage is that the adsorption capacity is limited and can only play an auxiliary role.

3. Photocatalyst to remove formaldehyde, photocatalyst is one of the fastest ways to remove formaldehyde, and it is also the most effective and safest method at present. Its principle is to spray the liquid products containing nano-scale titanium dioxide on the surface of indoor walls and furniture materials, using titanium dioxide catalysis, under the condition of light, formaldehyde and other harmful substances in the air are decomposed into carbon dioxide and water, and there are also many classifications, such as photocatalyst wood essential oil, leather aldehyde removal care solution, etc., which can be used in different places, with a long duration and no secondary pollution.

4. Solid activated carbon, activated carbon is physiosorption, very safe, although harmless to the human body, small size, can be placed at will. The disadvantage is that it is easier to saturate and needs to be replaced regularly, compared to Maya blue, which has a good adsorption effect and is not easy to saturate, it is a good choice.

5. Air purifier, air purifier has a certain effect in adsorbing formaldehyde, especially at the beginning, but its principle is the same as activated carbon, and it is easy to saturate after using it for a period of time, and the effect will decline. Summary: Therefore, everything involving adhesives, including wood-based panels, coatings, carpets, and furniture will contain formaldehyde, which will cause serious harm to human health, so we must not be careless.

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.

There are many ways to remove formaldehyde, and the commonly used ones are activated carbon, photocatalysts, Mayan blue and formaldehyde scavengers. Here are a few specific ways to do this:

1. Open windows as much as possible for ventilation.

2. With some photocatalyst sprays, choosing a good product is the key, and some products will have secondary pollution.

3. Put some Mayan blue in the cabinet, drawer and other smelly places, and use its nano-sized pores to absorb harmful gases.

4. If you have the conditions, buy an air purifier, but it is generally quite expensive, and the good ones are tens of thousands of yuan. If the smell at home is big, then use the above four points, if the smell at home is not big, then open the window to ventilate, and then buy some Mayan blue and put it at home.

Finish. Try to avoid the pitfalls:

1. Use black tea, pineapple, orange peel, and air freshener to remove the taste. This method is the most important.

Because it has no effect at all, it basically masks the smell of harmful gases, but makes you relax your vigilance. Don't kid yourself.

2. Some people say that potted water at home can absorb formaldehyde, which is groundless, and some people say that plants can absorb formaldehyde. Plants are available.

To adsorb a little formaldehyde, but it is negligible and completely negligible.

3. White vinegar is a folk method, which has no effect at all, please use ozone with caution, it is harmful to the human body. There are also some sprays with plant extracts, please keep your eyes open and use with caution.
