Is there a long formaldehyde release cycle? When is formaldehyde released the most

After the renovation is completed, many people will open the window for ventilation for two or three months, or more than a year and a half, but opening the window for ventilation only disperses the free formaldehyde and other pollution sources in the air, and cannot remove the release source.

The release period of formaldehyde is 3-15 years, which is by no means solved by a few months of ventilation.

After the dissection of the man-made panel of furniture, magnified 6 million times, it was found that free formaldehyde that did not complete the complexation reaction abounded, because formaldehyde is a gas normally, so it will continue to volatilize; Because the diameter of the formaldehyde molecule is only, and the distance between the molecules of the plate particles and the molecular gap of the adhesive exceeds dozens of nm, even the distance between the macromolecules on the paint surface greatly exceeds the size of the formaldehyde molecule, so the formaldehyde molecule is almost unhindered by the volatilization from the depth of the plate into the indoor air.

Therefore, after purchasing furniture, it needs to be placed according to the specific situation before moving in, and it is best to ask an authoritative and qualified testing agency to test the indoor air qualityIf you meet the requirements of China's "Indoor Air Quality Standards" (GB T18883-2022), you can move in. Conversely, internal cleaning should be used to improve indoor air quality.

Using internal cleaning technology, formaldehyde, benzene, toluene, xylene, ammonia, TVOC, odor and other pollution sources can be used in only 3 days, eliminating the phenomenon. Internal cleaning technology has ended the history of "20 years of chemical agents to remove formaldehyde".

After the renovation, do an internal cleaning, that is, "whole house detoxification"., you can:

1. Exempt from the cost of removing formaldehyde and removing formaldehyde many times;

2. Avoid the harm of decoration odor and secondary pollution of volatiles in aldehyde removal potion;

3. There is no need for the house to be vacant, ventilated for several months, half a year or even more than a year to release pollutants;

4. Safe occupancy, all pollutants are far below the national standard limit, and even close to 0;

5. Protect the immune system of the whole family from harm, and protect the health of the elderly, children, women and patients.

Flowchart of clean technology governance within the country.

Formaldehyde is a volatile gas with a long release cycle, and its specific gravity is similar to that of air, so after volatilization, it is mixed in the air, whether it is above or below, there will be formaldehyde, normally, there will be slightly more above.

Formaldehyde is quite stable in the environment, when the concentration of formaldehyde in water is 5 mg l (20), the observation results show that it can remain constant for 5 days. When the concentration of formaldehyde in water is <20mg l, it can be degraded and digested by acclimated microorganisms in the aeration tank.

When the content is 100mg l, it can inhibit the oxidation of organic matter by microorganisms. When the formaldehyde content in the water is 500mg l, the biological oxygen consumption process is all stopped, and the microorganisms in the water are killed.

The maximum formaldehyde emission is high when the temperature and humidity are high.

Hello, please ask me to remove formaldehyde, should it be better to open the window during the day or at night.

The release of formaldehyde is related to temperature and humidity! If the temperature is high, it will be released quickly!

1. The boiling point of formaldehyde solution is minus degrees, when it is greater than minus zero, formaldehyde will be released, and the indoor formaldehyde is caused by the desorption of aldehydes in the high temperature environment of phenolic resin and urea-formaldehyde resin, although it is not a pure formaldehyde solution, but it cannot be said that it will not be released when it is lower than minus 19 degrees, but the amount of release will be reduced a lot, and with the increase of indoor temperature, the amount of indoor formaldehyde will be released more and more.

2. According to the chemical properties of formaldehyde, soluble in water, the higher the temperature and the volatilization of fast characteristics, when the indoor temperature reaches about 30 degrees, the humidity reaches more than 50%, this time is very conducive to the volatilization of formaldehyde, if there are good ventilation conditions, the release of formaldehyde at this time is the most, and the amount of formaldehyde released can reach more than 19 times of the usual.

3. Summer is the season with the most formaldehyde release, and the high temperature and high humidity environment in summer is very conducive to the volatilization of formaldehyde. A closed environment can multiply the concentration of formaldehyde in the room**, which is very bad for our health. In addition, it is recommended that users who have just completed the decoration of the new house, do not rush to move in, it is best to go through a summer, the first summer of the decoration is completed, when the formaldehyde volatilization is the most, do not rush to move in at this time.

Formaldehyde is continuously released, the release period can reach 3 to years, the release source is relatively wide, and it is difficult to remove the bottom of the stool in a short period of time, so how should we deal with it, the current more mature is to stabilize the concentration of formaldehyde in a safe range, and recommend several easy-to-use methods to everyone.

1. If you want to remove the indoor formaldehyde and odor as soon as possible, the first thing to do is to open the window for ventilation, open the cabinet doors and drawers at the same time, and dilute and discharge the formaldehyde to the outside through air convection. Although this step is simple, it is also necessary to pay attention to the weather conditions, so as not to break the newly renovated home environment with strong wind and rain.

<>4. The fan can play the role of "inducing air" to accelerate the discharge of the gas containing free formaldehyde in the room to the outdoors, and this method is only useful for the house with poor ventilation, and has little effect on the house with good ventilation effect.

5. High temperature and drying can accelerate the volatilization of formaldehyde and other harmful substances, so you can take out drawers, movable furniture, mattresses, etc., to the balcony for ventilation and drying, and excite other furniture that can not be dried, which can be fumigated at high temperature, and the volatilization of formaldehyde can be accelerated with garment steamer, steam machine mop, and high temperature steam
