How to remove formaldehyde produced after the renovation of an old house

Try to buy eco-friendly materials. Don't know the brand? Just pick the expensive one and buy it.

Open the window for ventilation and let it sit for a month. Don't just live in it after it's renovated. Of course, it's best not to live in the summer!

Green plants are useless, and there are a lot of fools on the Internet.

Now there are many ways to remove formaldehyde on the market, and the best way is actually to open windows for ventilation, but the release time of formaldehyde is 3-15 years, which takes a long time, and formaldehyde can be removed in the following ways. 1. Activated carbon adsorption. Activated carbon to remove formaldehyde is a relatively simple, cheap and practical method, physical adsorption, not easy to cause secondary pollution, no chemical additives, no impact on the human body.

If you want to recycle, you must take it to a sunny and ventilated place outdoors for a day before taking it back. It's useless to just leave the charcoal bag there. 2. Photocatalyst decomposition.

Photocatalyst is a catalyst that can decompose harmful organic compounds such as formaldehyde, toluene, and TVOC into harmless gases under the action of light, so as to achieve the purpose of removing formaldehyde. You can appropriately use some photocatalyst wood essential oil, leather formaldehyde removal care solution and other products, remember that the photocatalyst needs to react under the condition of light, and the more light the better. 3. Chemical purification method.

The chemical purification method is a method that uses chemical reagents to neutralize formaldehyde or seal formaldehyde through chemical agents to prevent formaldehyde from volatilizing. Generally speaking, it is difficult to implement the method of neutralization by chemical reagents, and it is easy to produce secondary pollution; The way to prevent the volatilization of formaldehyde is to treat the symptoms rather than the root cause. Users who urgently need to remove formaldehyde should be operated and used by professionals.

4. Formaldehyde air purifier. The air purifier method is a method of using an air purifier to remove harmful substances such as formaldehyde in the air. This method of removing formaldehyde is somewhat similar to the activated carbon adsorption method, because the general air purifier is adsorbed and filtered by the activated carbon filter to adsorb and filter toxic substances such as formaldehyde.

For example, the Langkong aldehyde energy king air purifier is very worth buying.

In conclusion, choosing the right and environmentally friendly materials and taking appropriate measures can effectively reduce indoor formaldehyde levels, and these methods are crucial in the renovation of old houses.

Formaldehyde is a very important issue when renovating old houses, because it is a harmful substance that may cause harm to human health. Here are some ways to remove formaldehyde from rotten skin in old houses:

1.Ensure ventilation: It is very important to maintain ventilation when decorating old houses, which can reduce the concentration of formaldehyde in the air, and by allowing indoor air circulation, the concentration of indoor formaldehyde can be effectively reduced.

In the summer, you can open the windows in the morning and evening to improve the indoor air quality by using natural ventilation, and in the winter, you can use the fresh air system, ventilation fans, etc.

2.Choose low-formaldehyde materials: When decorating old houses, try to choose low-formaldehyde materials, such as some green wood, formaldehyde-free particleboard, formaldehyde-free paint, etc.

These materials can not only effectively reduce the concentration of formaldehyde in the room, but also reduce the harm to the human body.

3.Clean indoor air: After the renovation of the old house is completed, the room should be cleaned to remove the residual formaldehyde in the room, and some professional air purifiers, plants, etc. can be used to remove harmful substances in the indoor air, so as to improve the indoor air quality.

4.Strengthen maintenance: In daily maintenance, the room should be cleaned, cleaned, ventilated, etc., and the air filter should be replaced regularly, which can effectively reduce the concentration of indoor formaldehyde and keep the indoor air fresh.

In short, when decorating old houses, we should pay attention to indoor air quality, choose green materials and appropriate cleaning methods, minimize the concentration of indoor formaldehyde, and protect human health.

In the decoration of old houses, the removal of formaldehyde is an indispensable and important link. Formaldehyde is a harmful gas, light pollution can cause eye pain, headaches, throat discomfort, etc., and heavy pollution may lead to serious diseases such as cancer. Therefore, it is very important to remove formaldehyde in the decoration of old houses, and we will introduce some methods for removing formaldehyde in the decoration of old houses.

1.Plant adsorption and rot carrying method.

Formaldehyde in the air is absorbed through the respiration of plants, and then converted into microbial metabolites for discharge. The better plants are spider plants, cacti, aloe vera, ivy, etc. After renovation, place some appropriate plants in the room to effectively reduce the content of formaldehyde.

2.Sealing method.

In the decoration, the use of well-sealed raw materials to reduce the space for furniture, flooring and other areas to release formaldehyde. At the same time, in the selection of coatings, it is necessary to choose low-volatile coatings, such as environmentally friendly emulsion paints, water-based wood coatings, etc., and pay attention to ventilation and detoxification when painting.

3.Laterite method.

When decorating, laterite can be used to cover the surfaces of the ground, walls, gypsum boards, etc., and the laterite has a good absorption effect on formaldehyde, which can effectively reduce the content of formaldehyde in the air in the building.

4.Activated carbon adsorption method.

Activated carbon has a strong physical adsorption effect, which can adsorb harmful gases in the air, such as formaldehyde, ammonia, benzene, etc. After the renovation, place an appropriate amount of activated carbon in the room, which can effectively absorb harmful gases such as formaldehyde and improve indoor air quality.

5.Ventilation method.

After the renovation, open the windows for ventilation as soon as possible, so that the gas released by the indoor formaldehyde is gradually discharged and fresh air is exchanged. It is recommended to fully ventilate the room before decoration, which helps to discharge harmful gases in the room, and also creates better conditions for subsequent decoration to remove formaldehyde.

In short, in the decoration of old houses, removing formaldehyde is an essential task and is essential for home health. I hope that the above methods of removing formaldehyde can help to decorate the family.

The decoration of old houses is a common situation, and the first problem that is often faced at this time is indoor formaldehyde pollution. Formaldehyde is a volatile organic compound, which is found in new furniture, decoration materials, paints and other items, which can cause harm to the human body. How to remove formaldehyde?

Here are some ways to help you:

1.Ventilation.

Indoor ventilation is the easiest way to remove formaldehyde, due to the strong volatility of formaldehyde, indoor window ventilation can quickly reduce indoor formaldehyde content, it is generally recommended to ventilate at least 1-2 hours a day. Pay attention when ventilating and avoid ventilation during highly polluted times, such as haze or heavy traffic, otherwise it will be counterproductive.

2.Formaldehyde adsorption by green plants.

Green plants have a good effect on the adsorption of formaldehyde, such as aloe vera, spider plant, tiger tail orchid, dragon bamboo and other plants have good formaldehyde adsorption properties, and green plants can be used to reduce indoor chemicals.

3.Air purifier.

An air purifier can filter the indoor air and reduce pollutants such as formaldehyde and odors, so it is recommended to choose an air purifier with a HEPA filter or activated carbon filter.

4.Photocatalysts.

Photocatalyst is a relatively new purification method, and the use of photocatalyst purification indoors can quickly reduce formaldehyde content. Photocatalyst refers to the decomposition of harmless substances into water and carbon dioxide through ultraviolet rays and catalysts, which has good environmental protection.

5.with formaldehyde adsorbents.

It is a material that can effectively absorb formaldehyde attached to Chaishan, which is convenient to use, and only needs to put activated carbon indoors to play a good role in purification. Of course, when using activated carbon, you need to pay attention to regular replacement.

The above are some common methods to remove formaldehyde, but it should also be noted that in most cases, formaldehyde still comes from decoration materials and paints and other items, so when decorating old houses, it is necessary to choose environmentally friendly materials as much as possible, use water-based paint and other environmentally friendly materials to reduce the content of indoor formaldehyde.

This depends on more than less, whether it exceeds the standard. It is recommended that after the furniture is bought, ventilate it more every day, and then put a few bags of alcoidan on each piece of furniture to adsorb and decompose, so that formaldehyde can be removed quickly, and it will not rebound, and you can live at ease.

Furniture is also divided into *** and poor quality, more solid wood furniture formaldehyde is naturally less, glue is more wood furniture formaldehyde is naturally more, it is recommended to buy furniture, or need ventilation for 1-2 months and then move in will be more assured!

1. Generally speaking, on the issue of whether formaldehyde is serious in the decoration of second-hand houses, we must first look at the materials used in the decoration process. If the material is more environmentally friendly, the formaldehyde content is not high; If the decoration materials are not good, the formaldehyde content will generally be higher.

2. Renovation is generally about turning old things into new things. During the renovation process, pay attention to several materials with high formaldehyde content. There is still a situation in second-hand housing.

When the new owner buys a house to live in, there is still a phenomenon of excessive formaldehyde when it has never been renovated. This can only mean that the previous owners are renovating. The materials used contain formaldehyde, which is not environmentally friendly and has not been treated with formaldehyde.

3. The dormancy period of formaldehyde changes with temperature. When the temperature is high, it is easy to emit formaldehyde. The other is the self-dilution decomposition time of formaldehyde is 3-15 years.

During this time, there is a high possibility of formaldehyde exceeding the standard. Therefore, in the absence of decoration, the formaldehyde detection of second-hand houses cannot be less, so that problems can be detected as soon as possible, dealt with in a timely manner, and a healthy living environment can be ensured.

<>1. Adults generally need to move in within 2-3 months after the decoration of the second-hand house, in the case of ventilation, if the formaldehyde removal method of the second-hand house decoration is used well, the check-in time can also be shortened, and some plants can be raised in the room.

2. Pregnant women should be at least half a year, and the longer the better, because the impact of toxic pollutants such as formaldehyde in the decoration of second-hand houses on the fetus is extremely serious, ranging from poor physical fitness to severe malformations and leukemia.

3. It is best for the baby to move in after a year. After the decoration of the second-hand house, it is recommended to have good ventilation, open doors and windows, it is recommended to put more green plants, and it is best to buy an air purifier to reduce indoor pollution.

4. It takes at least 3-6 months for the elderly to move in, because the elderly have low immunity and are prone to illness due to the pollution of second-hand house decoration.
