How long does it take to remove formaldehyde indoors?

Depending on the root environment, this time and governance cycle are also different. For details, you can consult SGS. They offer a comprehensive range of testing services.

Room pollution is mainly furniture, the highest concentration of formaldehyde pollution in summer, generally a few months after the decoration can only be moved into the newly renovated room, even if the ventilation for 2 months to half a year, the formaldehyde excess rate is still half. This is the result of the staff of the Liaoning Provincial Environmental Monitoring Center Station after monitoring the formaldehyde indicators of more than 60 households and workplaces. "Due to modern home decoration and furniture, formaldehyde is usually used as a raw material for adhesives in the interlayer of wood-based panels, and it is extremely difficult to volatilize, and it usually takes 8 to 15 years to volatilize off.

Zhang Zhuoqun, deputy director of the indoor monitoring room of the Shenyang Environmental Monitoring Center Station, said. In fact, this kind of indoor pollution exists in almost every family, such as a bed, there is formaldehyde in the interlayer of the bed board, and this toxic gas will spread at night and become the main source of indoor pollution. Desks are a major source of pollution in the office, and when you use your computer, the rate of formaldehyde diffusion will increase as the temperature increases.

These sources of pollution directly threaten the lives and health of every citizen. The highest concentration of formaldehyde pollution in summer A simple way to deal with formaldehyde is to ventilate, but in the survey, the ventilation situation is very unsatisfactory. According to statistics, the ventilation time is shorter than the rate of pollutants in the house is high, the basic unventilated house throughout the year, the formaldehyde excess rate is as high as 80, the excess is serious, followed by the ventilation of two months to half a year of the house, the formaldehyde excess rate reaches 50, the ventilation of more than half a year of the house pollution is the lightest, the overall air quality is the best.

In summer, the pollution concentration of formaldehyde and ammonia is significantly higher than that in other seasons, which is undoubtedly caused by the diffusion of formaldehyde from wood-based panels due to evaporation. "The larger and more complex the amount of decoration (even if the decoration materials of regular manufacturers are used), the more serious the exceedance, usually 3 5 times the exceedance; The decoration is simple and the use of regular manufacturers of decoration materials at the same time is less polluting, usually exceeding the standard by 1 2 times. The report emphasizes.

According to reports, the public should choose high-quality healthy and environmentally friendly building materials that meet national standards when decorating, and avoid using low-quality decoration materials. At the same time, it is not advisable to move in immediately after decoration, the windows should be opened every day for ventilation, and generally can only be moved in a few months after decoration, and ventilation should also be strengthened after moving in to minimize the degree of indoor pollution. For indoors, especially in bedrooms, baby rooms, etc., some flowers and plants that adsorb formaldehyde should be raised, which can also reduce pollution.

Citizens with conditions can also buy air purification devices for treatment, but they should be used carefully to prevent secondary pollution.

Generally, indoor formaldehyde can only be moved in for more than three months, which does not mean that formaldehyde is naturally released. Formaldehyde is not stored for a month or two months, but for up to ten years. Usually pay more attention to the removal of formaldehyde.

It is a good choice to buy materials to remove formaldehyde by myself, I bought it myself, and then I usually have a variety of pothos in my home, pay attention to more ventilation, and spray more photophyllin if I have nothing to do, and it will be removed soon. Then the following suggestions for you to take a look at.

1. Air exchange method: air exchange is ventilation, the higher the indoor and outdoor air exchange rate, the better the effect of reducing indoor pollutants.

2. Physical adsorption method: the use of activated carbon and other products to adsorb harmful gases, and at the same time assist ventilation, which can effectively improve the effect of removing pollution, and better is the decomposition and removal of alginate materials.

3. Plant purification method: green plants used to decorate the living environment can also purify indoor air. For example, monstera, evergreen ivy, iron tree spider plant, aloe vera, etc.

Generally, after the renovation is completed, you can move in after three months, but if you have children, pregnant women or the elderly at home, it is recommended to move in after half a year. In normal cases, it is necessary to use photophyll materials with ventilation and a variety of green plants. Pay attention to the work of removing formaldehyde!

How to remove formaldehyde is a problem that every new house owner has to face, there are many methods on the market to remove formaldehyde, dazzling, difficult to distinguish between true and false, choose the wrong method to delay the time is small, inhaling formaldehyde for a long time without knowing it, the body is big, the following is for you to introduce some small methods to remove formaldehyde, so that you can efficiently remove formaldehyde.

1.Open all doors and windows to promote air circulation, so that harmful gases can be discharged to the outside through the flow of air, which is simple and effective. However, this method should be used to maintain ventilation for a long time, and a large fan can also be used to enhance the wind and assist in ventilation.

In this cycle, forced ventilation for a month, the odor in the room will be greatly reduced. For some movable furniture, try to place vents so that odors can be discharged directly to the outside.

4.Choose plants that can adsorb formaldehyde, pothos, aloe vera, spider plant and other plants can adsorb a certain amount of formaldehyde pollution, and can indeed remove formaldehyde. Placing some greenery in your new home can also help to beautify the room and freshen the air.

However, the adsorption capacity of plants is relatively limited, and if the formaldehyde concentration is too high, the plants will wilt and die.

5.Ventilation is an indispensable method of removing formaldehyde indoors, but when the outdoor wind is not strong enough, it is necessary to strengthen ventilation. At this time, you can buy a high-power industrial fan to assist in the removal of harmful gases in the house, which can accelerate the circulation of air inside and outside the house, which is of great help to remove indoor decoration pollution.

6.High temperature can promote the release of formaldehyde, reduce the total content of formaldehyde inside the material, and reduce the release of formaldehyde in the later stage

In fact, the best time to remove aldehydes in a new house is best before moving in.

Method 1: The first thing you have to do is to ventilate the new house, and at the same time open the cabinets, wardrobes and drawers of the new house furniture, dilute the formaldehyde and discharge it to the outside through air convection. Although this method is simple, it is also necessary to pay attention to the weather conditions, when the air conditioner is turned on in the hot summer when the doors and windows are closed, and when the windows cannot be opened in the cold in winter, the ventilation and windows are limited.

Method 2: After opening the window for ventilation for a period of time, although it is possible to discharge harmful gases such as formaldehyde indoors to the outdoors, the residual amount of formaldehyde is still very large for the cabinets and drawers of furniture and the angle of sealing. Combined with the use of biological enzyme formaldehyde scavenger, to adsorb the residual formaldehyde, to remove formaldehyde, the effect will be better.

Method 3: Activated carbon is a commonly used material in addition to formaldehyde, because there are many small voids on its surface, which can adsorb free formaldehyde molecules, but the traditional activated carbon adsorption capacity is limited, easy to saturate, and can not be decomposed, and needs to be replaced in time, otherwise it will produce new chemical pollution, which is very dangerous.

The best time to remove formaldehyde is in summer and autumn, after the house is renovated, in addition to taking physical formaldehyde removal, such as placing activated carbon in the room, undelicious apples or pothos and other plants, there is also enough time to open the windows for natural ventilation, and you can move in when the weather is cool.

What time is the best time to choose for formaldehyde removal? In fact, 99% of people have chosen the wrong best time, in fact, the formaldehyde treatment is carried out simultaneously with the decoration, and the effect is more than 3 times stronger.

In summer, the high temperature in summer makes formaldehyde emit quickly, and the treatment is more effective.

The hot summer is the most serious time for the volatilization of harmful gases such as formaldehyde, and now the pollution after the decoration of the new house has become a common phenomenon, and all the friends who are ready to move in after the home decoration will question whether the indoor air is healthy, whether the formaldehyde exceeds the standard, etc. Therefore, Guangzhou Green Optimal Environmental Protection suggests that you can test the formaldehyde concentration after decoration, and if it exceeds the standard, it will be treated immediately, so that the whole family can live with more peace of mind!
