Formaldehyde is released more during the day or at night

In fact, the amount is about the same, because the decoration materials contain more formaldehyde, all kinds of glue, such as floor glass glue plates, are the release of formaldehyde, and formaldehyde goes deep into its interior, it is easy to exceed the formaldehyde when the ventilation is not smooth, so how should we deal with it, recommend several easy to use to everyone.

1. Wise Stone.

It is currently a relatively cost-effective formaldehyde removal product, its advantage is that it can be decomposed into water and carbon dioxide at the same time of absorbing formaldehyde and harmless substances to the human body, because of its decomposition characteristics, so that it will not appear adsorption saturation and indoor secondary pollution, and suitable for various types of environmental use. In addition, its removal rate is also dozens of times that of traditional adsorbent materials. When choosing, it is important to note that it is a gray ore with an irregular shape and is not a round particle.

2. Wind fan.

If you want to eliminate formaldehyde in the house as soon as possible, you can put a floor fan at home after the decoration is completed, and open the window for ventilation at the same time, if the outdoor wind allows, the fan can increase the flow speed of indoor and outdoor air, reduce the indoor formaldehyde content, and speed up the release of formaldehyde, it may be the most effective and low-cost way

3. Plants.

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.

Fourth, photocatalysts.

Photocatalyst is a product that can decompose formaldehyde into carbon dioxide and water through light or ultraviolet irradiation, which can be effective for a long time at one time, but its requirements for action are relatively high, and the effect is not particularly obvious, so it is recommended as an auxiliary method when used.

Fifth, the fresh air system.

The fresh air system is similar to the ventilation method of removing formaldehyde, but there is no need to open the window when in use, and the air delivered to the room is filtered, and it is also used when it exceeds the standard.

Summary: Formaldehyde is very harmful, and the selection of furniture and decoration materials should be strictly controlled when decorating new houses to reduce formaldehyde from the source.

The volatilization of formaldehyde is related to temperature, and the higher the temperature, the faster the volatilization.

Temperatures are warmer during the day than at night, so more is released during the day. However, if you sleep with the window closed at night, you will feel that you are released more at night.

It is generally daytime because the temperature is higher during the day. However, in some places (such as the south), the temperature difference between day and night is not large, and the amount of formaldehyde released is about the same.

The reasons why formaldehyde soars at night are as follows:The speed of formaldehyde release is related to temperature and humidity, the higher the temperature, the greater the humidity, the amount of release will increase, sleep at night is generally closed window, after closing the window, the indoor air will not circulate, the temperature will also increase, and the release of natural formaldehyde will increase.

In order to accurately detect the formaldehyde content in the room, it is necessary for professionals to use professional instruments, and because formaldehyde is the overall composition of volatile organic compounds, the detection cost is relatively high. If you don't need accurate testing, you just want to know the approximate content of formaldehyde at home, you can go to the Internet or home market to buy a formaldehyde self-test box for home use.

Formaldehyde excess treatment method.

1. If the indoor formaldehyde exceeds the standard, it is necessary to open the doors and windows to replace the indoor and outdoor air, so as to reduce the indoor formaldehyde concentration. However, it should be noted that in the formaldehyde removal stage, it is not possible to live in people, so it is necessary to pay attention to the changes in the weather at all times, try to go to the new house before the rain, close the doors and windows, and prevent indoor soaking.

2. The use of activated carbon can also effectively adsorb formaldehyde to reduce formaldehyde concentration. It's just that the activated carbon is easy to reach a saturated state and needs to be replaced in time to avoid secondary release, which will lead to a re-increase in the indoor formaldehyde concentration. The saturation period of activated carbon is generally 22 days.

3. Placing a few more pots of green plants indoors can also absorb formaldehyde in the air, and the decorative effect is also relatively good. If you find that the green plants are wilting quickly, then the indoor formaldehyde concentration is very serious and should be handled with caution.

The newly renovated house releases the most formaldehyde in the first three months, and the formaldehyde release of furniture or various home improvement materials will reach the peak within 3 5 months after opening the package, and it will enter a slow and small amount of release after half a year. The higher the temperature, the more and faster it is released, so it is the summer when it is released the most.

Formaldehyde is emitted fastest in summer.

The volatilization of formaldehyde is closely related to air temperature. In general, the higher the temperature, the more likely it is that formaldehyde in furniture will volatilize. The hot summer is the most "rampant" season for formaldehyde volatilization:

The high temperature weather directly leads to the indoor formaldehyde release is 20 to 30 higher than usual; For every 1 rise in room temperature, the volatile formaldehyde in wooden furniture and floors will double the formaldehyde concentration in the indoor air.

Summary. The volatilization of formaldehyde is closely related to temperature, because the boiling point of formaldehyde is 19 degrees Celsius, and the higher the temperature, the greater the release, and vice versa.

Because the temperature at night is usually lower than during the day, the volatile emission of formaldehyde at night is relatively small, of course, if you close the doors and windows at night, it is different.

At night, the doors and windows were closed overnight, and the formaldehyde content was high. It is recommended that you take corresponding measures to deal with formaldehyde: First: open windows for ventilation and keep air circulation indoors or in the car. Second: the method of physical adsorption is adopted.

When sleeping at night, the room should not be directly ventilated.

Formaldehyde levels are higher at night than during the day.

Second: the method of physical adsorption is adopted. When sleeping at night, the room should not be directly ventilated.

2. The second stage is the winter heating period, the indoor temperature is low, with the arrival of summer, the temperature rises sharply, and the formaldehyde concentration may exceed the standard.

I measured formaldehyde tonight, but the doors and windows were open.

It's just that the weather is not very good and it has been raining.

The temperature is low on the night of the month, the doors and windows are closed, and the new posture system is opened; After May, when the temperature has exceeded 20 degrees at night, the windows of the rooms are closed and the fresh air system is turned on. The other rooms are open and airtight.

The more filial piety talks about the more damp formaldehyde is released, the reason is: formaldehyde is very easy to dissolve in water, when the room is humid, the water molecules in the air.

Formaldehyde, colorless and irritating gas, has reducing ability, especially in alkaline solution, the reducing ability is stronger. It can be burned, and the vapor and air form a **sexual mixture, **limit.

7%-73% (volume), the ignition point is about 300 degrees Celsius.
