The new house has just been decorated. What pollution is there besides formaldehyde pollution? What is the solution?

This is an article with the number of 154 from the home furnishing department.

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 a rental service company, everyone is also worried about:

Does my formaldehyde exceed the standard?

How long can I move in after the renovation of the new house?

What, except formaldehyde?

From a health point of view, decoration pollution is not only formaldehyde, but also harmful substances such as TVOC. As the biggest pollution problem encountered in decoration at present, formaldehyde is very harmful to human body (what harm, you can Baidu yourself ~ ~ ~).

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. Glass glue

Glass glue is a very important accessory in decoration, such as glass doors and windows, bathroom cabinets, cabinet countertops, integrated ceilings and other decoration basically need it, which is also the biggest source of formaldehyde.

Step 2 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 ~ ~)

Among them, the solid wood board made of all wood (logs) has less formaldehyde content, high environmental protection and high cost. Good edge sealing technology, such as solid wood particle board, is also very safe to lock a small amount of free formaldehyde. At present, most furniture brands use this material.

A large number of formaldehyde adhesives are used in the production and processing of blockboard, and the formaldehyde emission is very high. Andy doesn't recommend it.

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.

4. Floor adhesive

Adhesives used in flooring processing, such as trialdehyde glue, all contain formaldehyde.

5. paint VS wallpaper

The organic solvent of coating is formaldehyde. Although there are "anti-formaldehyde coatings" now, the anti-formaldehyde effect remains to be verified.

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.

6. Flexible packaging furniture

Fabric and leather art may cover artificial boards, such as medium density fiberboard and plywood, which contain formaldehyde. If you don't pay attention, it will also cause formaldehyde pollution.

Two-step elimination of formaldehyde

1. Control formaldehyde emission from the source

1. 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.

Therefore, when choosing building materials, we should try our best to choose products produced by regular enterprises, and pay attention to choosing products with small pungent smell when buying, because the greater the pungent smell, the higher the release of harmful gases.

The simplest way is to ask for a quality inspection report when buying furniture to see if the formaldehyde emission of furniture is within the scope allowed by national standards.

2. Regular home improvement companies guarantee the construction technology.

Choosing a regular home improvement company can not only ensure the decoration technology, but also reduce the decoration pollution caused by unqualified technology.

Step 3 avoid ornate decorations

It is said that it is hooliganism not to talk about dose and toxicity. If the decoration materials you buy are environmentally friendly, but your home decoration is piled up with a lot of wall paint and plates, the prosperous decoration will easily increase the amount of formaldehyde, leading to excessive formaldehyde. From this perspective, the simpler the decoration style, the more environmentally friendly it is.

Of course, we should also pay attention to the wind direction of soft and hard furniture at home, so that formaldehyde will spread faster when it flows.

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/cubic meter needs 1.800 pots of radishes to reduce formaldehyde to 0. 1 mg/cubic meter during the day, and ensure that formaldehyde is not released during the process of absorbing radishes.

Some people say that activated carbon is used for adsorption. Such as air purifiers, bamboo charcoal, etc., the filter element contains a lot of activated carbon, but all kinds of activated carbon, like diatom mud, have the problems of only adsorption without degradation and easy saturation, especially in the whole adsorption process, you can't see, touch or know whether it has been adsorbed.

It can be seen that the formaldehyde adsorption capacity of plants and activated carbon is really very small.

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.

1. Window 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.
