1. The formaldehyde in the new house exceeds the standard and the odor is serious. The first thing to do is to open the window for ventilation. When you open the window, you can open the wardrobe and drawers to fully release formaldehyde, and then release formaldehyde to the outside through air convection. Although this step is simple to operate, we should also pay attention to the weather. This method is not suitable for northern winter and southern rainy season! ! !
2. Activated carbon is a traditional physical adsorption material, which is well received in indoor and outdoor pollution control. It has large specific surface area and strong adsorption capacity, but its adsorption capacity is limited and it does not have decomposition function. It needs to be replaced regularly when it is used, otherwise it may produce secondary pollution when it is saturated.
4. Putting some green plants at home can also effectively remove odors, especially green radish, chlorophytum, aloe, tortoise shell bamboo, cactus and ivy, which can effectively absorb harmful gases. In addition, the popular large plants such as Christmas tree and Cinnamomum camphora can release a kind of fresh air, which makes people feel happy and is more suitable for removing the odor of new furniture.
5. Using air purifier to remove formaldehyde is a popular method in recent years, but there are many brands on the market now, so it is recommended to choose products marked with "in addition to formaldehyde" function. Be careful when choosing. It is not recommended to choose products below 1500. In addition to formaldehyde filter needs to be replaced regularly when used!
6. The release speed of formaldehyde mainly depends on two factors, one is temperature and the other is humidity, so we can use this characteristic of formaldehyde to keep the room in a high temperature and humidity state by using heaters and humidifiers, and then absorb the formaldehyde that has been released at home with ventilation or adsorption materials. This method is mainly to control formaldehyde lurking at home, and the effect is very good?

Go to formaldehyde in winter because heating will make indoor air circulate quickly, so everyone is asking what is the good way to go to formaldehyde in winter? I tell you here that if you want to remove formaldehyde, you must use reasonable means. Removal of formaldehyde, it has been reported before that the activated silicon in Tmall's flagship store of Zhuhai Goddess can effectively remove indoor formaldehyde and decompose it. It can also absorb toxic and harmful gases. You can try. If you feel bad, you can return it.

The recent incidents of formaldehyde exceeding the standard have caused the decoration pollution problem to attract the attention of netizens again. In addition to denouncing the manufacturers of decoration materials, everyone is also worried:
Does my formaldehyde exceed the standard?
How soon can I move in after the renovation of the new house?
China's Hygienic Standard for Formaldehyde in Indoor Air stipulates that the maximum allowable concentration of formaldehyde content is 0.08 mg/m3.
House decoration, how can we prevent formaldehyde from exceeding the standard?
Where does the formaldehyde in the decoration come from?
The formaldehyde caused by house decoration exceeds the standard, mainly because many decoration materials contain formaldehyde. Let's take a look at the materials with high formaldehyde content in the decoration and see which ones are used in your home!
1. plate
Commonly used boards such as furniture generally include solid wood board, solid wood particle board, ecological board, density board, joinery board and so on. No matter what kind of plate, glue is indispensable in the manufacturing process, so the formed plate will release free formaldehyde. However, as long as it reaches the national indoor board environmental protection grade E 1 ≤ 1.5mg/L, it is safe and environmentally friendly. (Of course, it is more environmentally friendly and better than the standard ~ ~)
paint
Paint is used in the production of wooden furniture such as cabinets and wardrobes, and paint is the main source of formaldehyde release from these furniture, so it is best to use furniture bought after opening more windows and ventilation.
3. paint VS wallpaper
The organic solvent of the coating is formaldehyde. Although there are "anti-formaldehyde coatings" now, the anti-formaldehyde effect remains to be verified. I still suggest using environmental protection coatings such as diatom mud and shell powder to solve formaldehyde pollution from the source. I have used diatom mud from Yunquan for customers, and the detection box has tested it, and there is really no formaldehyde.
Wallpaper is mainly influenced by basement membrane and glue. As for cheap PVC wallpaper, Andy suggests not to choose it, because there may be plasticizers containing volatile organic compounds.
Two-step elimination of formaldehyde
1. Control formaldehyde emission from the source
Choose environmentally friendly materials.
In the process of material selection before decoration, attention should be paid to the reduction of decoration pollution, and materials with less pollution and good quality should be selected as far as possible to control the release of formaldehyde from the source.
Second, how to eliminate formaldehyde after renovation?
Some people say that using plant absorption method. Chlorophyte, aloe, agave and other plants. Some organic compounds (TVOC) can be adsorbed by photosynthesis, so some plants can be put in to purify the air after decoration. However, eliminating formaldehyde is of little use.
A team specially experimented with radishes with high formaldehyde absorption efficiency: a house with a height of 100 square meters and a height of 3 meters and a formaldehyde value of 0.2 mg/m3 needs 1800 pots of radishes to reduce the formaldehyde to 0. 1mg during the day, and ensure that no formaldehyde is released during the process of absorbing radishes.
Some people say activated carbon and adsorption. For example, air purifiers and bamboo charcoal contain a lot of activated carbon in their filter elements, but all kinds of activated carbon can only be adsorbed but not degraded, which is easy to saturate. However, activated silicon and diatom pure do not have these problems, but they can be adsorbed and degraded, and the adsorption strength is dozens of times that of activated carbon, so Taobao Zhuhai Goddess flagship store can be obtained.
It can be seen that the formaldehyde adsorption capacity of plants and activated carbon is really very small.
Other methods
1 ventilation
In fact, to solve the problem of formaldehyde pollution, in addition to the compliant decoration materials, you can ask a professional in addition to formaldehyde company to handle it yourself. The best way is ventilation.
After renovation, all installed furniture such as wardrobes, cabinets, shoe cabinets, etc. Will be opened, and it is definitely one of the best ways to keep the windows open and ventilated.
Because high temperature will accelerate the volatilization of formaldehyde, summer is generally the best time for in addition to formaldehyde. If you close the door for a week and open the window for another week, the volatilization speed will be faster.
Of course, if there is heating in winter, you can also turn on the heating to accelerate the volatilization of formaldehyde, and then open the window for ventilation to let the formaldehyde in the air out.
2. Fresh air system
Through the fresh air system, the indoor air containing formaldehyde is led out of the room, and then the outdoor air is introduced to achieve the purpose of indoor and outdoor air exchange. This is also a way of ventilation, which has a good effect, but the price is relatively high.
Because the volatilization period of formaldehyde is as long as 10- 15 years, and the high volatilization period is as high as 2-3 years, it is unrealistic to completely remove it before moving in.
Therefore, Andy suggested that before moving in, professional testing institutions should be invited to check whether the formaldehyde concentration does not exceed the national occupancy standard of 0.08 mg/m3. If not, you can check in. If you exceed it, you must not stay for the sake of health. .
