How to remove formaldehyde in a new house? How to remove formaldehyde from a new house?

Indoor air testingOur country only recognizes the atmospheric sampling method, don't be deceived by the direct reading instrument or the six-in-one sampling instrument. Formal indoor air testing is to close the doors and windows and then use an atmospheric sampler to sample and collect air samples, and the samples are taken to the CMA laboratory for laboratory analysis in a standard environment. The results of the test will be issued with a CMA test report, and those that cannot issue a CMA test report are false (CMA institutions are not allowed to issue reports other than CMA format, that is, all data reports are illegal and untrustworthy).

When a new house is moved in or just renovated, it is necessary to test five conventional items: formaldehyde, benzene, toluene, xylene, and TVOC. Regarding these five test contents, our country has two testing standards:

One is "GB50325-2020", which is a mandatory national standard, which is generally used for tooling inspection....

The use of activated carbon to clear the taste of formaldehyde in the air, and even the effect of adsorbing formaldehyde, is the most commonly used method to remove formaldehyde, but we need to pay attention to the fact that although activated carbon has the function of adsorbing formaldehyde, it can not be infinitely adsorbed, if the formaldehyde content in the air is relatively large, then the amount of activated carbon must be very large, so we use the amount of activated carbon, and there is regular replacement, in order to achieve the effect of removing formaldehyde.

Plants can improve environmental pollution, so when decorating a new house, there is still a certain effect on placing some green plants indoors, these green plants can not only purify the indoor air, but also make the interior decoration appear more exquisite, but the effect of plant adsorption formaldehyde is not very good, can adsorb mild formaldehyde, if the formaldehyde concentration is higher, its role is relatively small, and some people will have pollen allergies, not all families are suitable for placing plants and flowers.

It is also possible to speed up the progress of formaldehyde treatment in new houses and shorten the waiting time for occupancy by taking some treatment measures (the cost is definitely lower than the rent) in their own way.

1. The most important thing is ventilation. Answer: The main decoration is just at the end of May last year, coordinates Hangzhou, the weather is relatively fine, natural ventilation is the most economical and effective way, no cost, especially in the warmer (hot) season, formaldehyde is volatile (19), at this time the effect of natural ventilation is very good, note, continuous window ventilation will be better than the effect of stuffy method.

2. You can use a floor fan to assist indoor air circulation, and the blowing effect on the open furniture is better, and then it can also be used at home without waste.

3. Activated carbon. Activated carbon is a class of materials, and its principle is physical adsorption of formaldehyde, and it should be noted that it must be coordinated with ventilation, because it cannot actively capture impurities such as formaldehyde, and air must flow through its pores in order to passively adsorb impurities and formaldehyde. **It is also relatively cheap, and it can also be put in the refrigerator and shoe cabinet to remove odors in the future.

4. Photophyllin formaldehyde scavenger, which is sprayed directly on the pollution source, can accelerate the release of formaldehyde inside, and at the same time can decompose formaldehyde and other decoration pollution. Compared with other chemical sprays, it does not require light and ultraviolet rays, is not a blocking agent, has no secondary pollution, and is recommended for families with babies and pregnant women.

Go to see some evaluations, you can find that the products in addition to formaldehyde have a certain effect, but to compare the best and the effect, that is, the cost performance, make a trade-off, some people feel that the materials are solid wood, metal-based, or can wait for a year and a half before moving in, that may indeed be the same light and ventilation, some of the check-in time is more tight, or they are more uneasy, there are pregnant women and children at home, and those who are sensitive to it, it is also worth using some.

The purifier is not necessarily a necessity for the decoration of the new house, it depends on the personal choice, the principle of the purifier is the internal circulation of indoor air, which is released again after the filtration device. Therefore, the filter needs to be replaced frequently, and if the ventilation conditions are good, it is basically not necessary. Or just turn it on at night when you go to bed.

Formaldehyde removal at home should be carried out in a variety of ways as much as possible, which is greatly conducive to more effective removal

1. Ventilation, as far as possible can experience a summer, with the release of high temperature weather, is conducive to the discharge of formaldehyde.

2. The purifier can be used at night if possible, and it is still ventilated during the day.

3. Photophyll, which plays a catalytic decomposition role under the condition that no external light is required, can continuously and effectively decompose the newly released formaldehyde, play the role of both symptoms and root causes, and can solve the problem of formaldehyde removal at one time, and there will be no formaldehyde.

4. Physical way to remove odor, formaldehyde is colorless and odorless, many families have taste, you can use salt water to wipe, high temperature fumigation to speed up the dissipation of taste.

5. The cabinet drawer should put some leaf mud for long-term adsorption, which is much better than ordinary activated carbon, does not need to be exposed to the sun, and can be recycled for 3 years.

Newly renovated new houses generally have heavy formaldehyde residues, which are very harmful to the human body. Therefore, it is necessary to remove formaldehyde. Let's talk about how to remove formaldehyde from newly renovated houses.

Long-term ventilation: Newly renovated houses generally need to open windows for ventilation for a period of time, and remove or dilute the residual formaldehyde through the natural circulation of air, which is also the most commonly used and original method.

Activated carbon: Activated carbon is a widely used aldehyde removal product, due to the internal structure, the adsorption capacity is strong, but the problem of activated carbon is the saturation period, which needs to be replaced in time, otherwise there may be a risk of secondary release.

Photocatalyst: A photocatalyst is a catalyst that originated in Japan and can chemically react with ultraviolet light to break down formaldehyde (HCO) into carbon dioxide and water, but due to its high dependence on ultraviolet light.

Air purifiers are mainly used to purify the air and remove formaldehyde and various pollution. Stevo air purifiers use a variety of technologies to effectively decompose and adsorb formaldehyde, odors, bacteria, dust, and other harmful substances.

The CADR value of STEVO KJ800F-A8L particulate matter is 900 cubic meters per hour, the CADR value of formaldehyde is 550 cubic meters per hour, the formaldehyde removal rate is high, the bacterial removal rate is high, the gas pollution level is up to F4, and the solid pollution level is up to P4!

Several ways to remove formaldehyde from a new house are as follows:

Villa Master

1. Ventilation method.

Opening windows to ventilate and remove formaldehyde is a common method used in every family, but only opening windows for ventilation depends on the speed of air flow can not remove formaldehyde, and other harmful gases may accumulate indoors over time. At this time, if we want to quickly remove formaldehyde, we also need to use an external force - a fan. The fan increases the speed of air flow and quickly expels formaldehyde outdoors.

2. Plant green plants.

After the renovation of the new house, no one will buy a green plant and put it in the room, although the green plant absorbs very little formaldehyde. Although plants such as pothos, spider plant, and tiger tail orchid cannot absorb formaldehyde, the effect of purifying the air is quite obvious, and it will have many benefits for the human body.

3. Activated carbon.

Activated carbon has a particularly strong adsorption capacity and can effectively absorb formaldehyde, as long as you put a living carbon in every corner of the home. Because activated carbon is very easily saturated, it usually needs to be replaced with a new one every two months. Activated charcoal does not have any effect on the human body, so you can use it with confidence.

In fact, my new house to find the past, in addition to formaldehyde professional companies, they brought a lot of instruments and materials, a lot of potions, in fact, the effect is not good, they mainly take the method of ventilation, I think to find such a company is a waste of money, you can, that is, after the new house is renovated, after half a year, ventilation is the best way to remove formaldehyde

1.Open all windows in your home to keep it ventilated; 2.Keep turning on and off the lights, the temperature rises, and the room temperature is lowered to let the formaldehyde volatilize as soon as possible; 3.Soak the black tea in hot water and place a pot of black tea water in each room.

Clause. 1. Open windows for ventilation.

The volatilization of formaldehyde will be related to temperature and humidity, ventilation can play a good role in removing formaldehyde, and it is relatively effective and the lowest cost. Generally speaking, you can open the windows during the day for ventilation, but at night you need to close the windows and close the windows in case of wind or rain.

Clause. 2. Use air conditioners, fans, and heating equipment.

In the process of natural ventilation, some cabinet doors have to be opened, only in the case of natural wind, you can use air conditioning, or relatively large fans, including heating equipment, to open the maximum to increase the circulation speed of indoor air. Generally, the window is closed first, and the air conditioning or heating equipment is turned on indoors to adjust to high temperature, so that indoor formaldehyde can be released more effectively, and then indoor ventilation is carried out, that is, the window is closed first, and then the window is opened after a period of high temperature, so that the repeated cycle is better and the effect is better.

Clause. 3. Plants.

Arrange some plants indoors, and plants are actually good helpers for removing formaldehyde! Generally, the plants that remove formaldehyde include monstera, spider plant, ivy, aloe vera and tiger pill orchid. It is recommended that some plants be placed in each space of the new house, which can play a certain role in removing formaldehyde, and the plants can also play a certain visual decorative effect.

Clause. 4. Air purifier or activated carbon, tea.

Air purifiers are also one of the ways to remove formaldehyde, and they can also sterilize indoor air. If you use active oxygen, it is recommended to take it out to dry for a short period of time after use, and then take it indoors to reuse it. It is feasible to place activated carbon and tea room in all corners of the space, which can be placed at random or in a centralized manner.

Formaldehyde is the main culprit of renovation pollution, and it is the indoor pollutant that new homeowners want to remove the most. There are also many methods and products for removing formaldehyde on the Internet, but most of them have not been proven to be useful.

1. Opening the window for ventilation is the best way to remove free formaldehyde, when the window is opened, there will be a steady stream of fresh air to dilute the indoor air containing formaldehyde to achieve the purpose of purifying formaldehyde, but the window is easily affected by the weather, and the effect is also affected by the house type.

6. Now the company in addition to formaldehyde can be seen everywhere, the industry is now very chaotic, and there is a deviation in the effect of formaldehyde removal in the first place, and the choice must be made of a reliable formaldehyde removal company

1. Ventilation.

Indoor air circulation, this practice can also be easily brought out of the outdoor odor and formaldehyde by the flowing air, and can also reduce the content of formaldehyde and odor in the indoor air, and can not reduce the harm to human health. Therefore, it is recommended that you ventilate the newly renovated new house for a period of time before moving in, which can also remove formaldehyde and odor in the room.

2. Activated carbon adsorption.

Activated carbon can play a role in purifying the air, it mainly relies on air as a medium, so that it can well adsorb harmful substances in the air, can remove indoor ammonia, formaldehyde, benzene is very good, and this product is also a non-polluting, non-toxic, non-... When using, as long as two to three dishes of household activated carbon are placed in each house, generally speaking, indoor formaldehyde and odor can be well removed within 72 hours.

3. Plant purification.

In general, this plant removal method is more suitable for relatively light environmental pollution, such as the pollution value is less than 2 times the national standard. At the same time, it is also necessary to choose the plants according to the different functions of the room and the size of the room. In general, for example, for example, a room of about 10 square meters, then it is more appropriate to consider putting two pots of plants that are meters high.

For example, aloe vera, spider plant and tiger tail orchid, these plants can remove formaldehyde and play a role in purifying the indoor environment.

4. Food deodorization.

Vinegar deodorizes, which can protect the paint surface of the wall with the right amount of evaporated water, and at the same time eliminate residual odors. You can use a basin or a small bucket of water to fill it with cold water, then add some vinegar, put it in a ventilated room, and open the furniture door. If you think it's enough, you can consider buying some pineapple, knowing that pineapple can also absorb the smell of paint, and at the same time, it can also exude the fragrance of pineapple, which can also speed up the removal of odors.
