What temperature does formaldehyde volatilize the fastest, and how much does formaldehyde volatilize

Formaldehyde volatilizes at a temperature of 19 degrees to 6 degrees. Formaldehyde is generally released quickly at 19 to 6 degrees. It will also volatilize formaldehyde in large quantities.

In summer, spring or heated winter, it is a time period when formaldehyde is highly volatile.

The temperature of formaldehyde volatilization should also be analyzed according to the climate of the south and the north, if it is 15 degrees indoors in the north, formaldehyde will generally begin to be released, if there is no timely treatment of formaldehyde, then it is likely to cause a lot of harm to the human body.

29 degrees Celsius.

Formaldehyde is a chronic volatile material with an evaporation period of up to 3-15 years. At 19-29 degrees Celsius, it begins to evaporate into the air. The release of formaldehyde is directly proportional to temperature.

The higher the temperature, the greater the amount of formaldehyde released. Space in the car is limited, and at high temperatures, concentrations can easily spike, which is why it is especially easy to smell odors in the car in the summer.

On automobiles, formaldehyde is widely found in various colloidal materials, such as hard plastics, floor glue, and leather seats in cars, all of which contain formaldehyde. In addition to the harmful gases that may be released from carpets, door interior decorations, headliners, seat assemblies, car wiring harnesses and other components, "summer is not only the best time to get rid of odors in the car, but also the time when the air pollution in the car is the most serious, so before driving, you must set aside time to open the windows for ventilation."

According to the physical properties of formaldehyde: the boiling point of formaldehyde is 19 degrees, and the flash point is 60 degrees. The higher the temperature, the faster formaldehyde is released.

When the temperature reaches 30 degrees, the release of formaldehyde will reach more than 19 times that of normal temperature.

Methods of removing formaldehyde.

1. Generally speaking, the ventilation method is the most common way to remove formaldehyde in our new house, which is to open the windows of the new house for ventilation and discharge the harmful gases from the room to the outside. Disadvantages: It takes a long time, and it generally takes more than three years for formaldehyde to be removed.

2. Formaldehyde deodorization method: formaldehyde deodorant, the capture and decomposition of harmful pollutants such as purple formaldehyde, benzene and ammonia, killing germs and harmful microorganisms of mites, purifying the air and eliminating odors.

More than 19 degrees will volatilize faster, so you can take out the drawers, movable furniture, mattresses, etc., to the balcony to ventilate and dry, but this method is not omnipotent, just expect this method to remove aldehyde is too slow, and there are many large furniture is inconvenient to move, so the following is recommended for you to remove some aldehyde methods, I hope to help you

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. 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.

3. Open windows for ventilation.

Open the window ventilation is the best way to remove free formaldehyde, when the window is opened, there will be a steady stream of fresh air will dilute the indoor air containing formaldehyde to achieve the purpose of purifying formaldehyde, but the window is easily affected by the weather, and the effect is also affected by the house type when used.

4. Formaldehyde remover.

Under certain conditions, formaldehyde scavengers react chemically with formaldehyde to produce other substances that are not harmful to health, so as to reduce the concentration of formaldehyde in the room. But it's also a chemical in its own right, and if used incorrectly, it can be another source of pollution indoors.

Fifth, the fresh air system.

The principle of the fresh air system is ventilation, the outdoor fresh air is filtered and transported to the room, and then the harmful substances containing formaldehyde are discharged outside to achieve the effect of removing formaldehyde.

Formaldehyde has been ranked second on the priority control list of toxic chemicals in China, which shows how high the toxicity of formaldehyde is, so the first step to renovate a new home is to remove formaldehyde, and the efficient method is to carry out several methods at the same time.

I used to work in Chengxiang District, unit decoration, I see that the formaldehyde removal product used by the decoration company is called Ye Duofen, a large bottle, it should be the same as the professional formaldehyde removal company. It is also sprayed in each room, in fact, you can also buy your own products and come back to spray, **It should be cheaper than hiring a professional company. Spray it a few times, and the formaldehyde effect will be up to standard.

Now that the decoration is finished, I don't dare to move in if I don't remove formaldehyde.

The higher the humidity, the greater the release. But formaldehyde is more closely related to temperature.

When formaldehyde is higher than 19 degrees, the amount of formaldehyde released begins to increase, and when it exceeds 30 degrees, it begins to increase geometrically. When formaldehyde is lower than 10 degrees, it stops volatilizing. This is the confusion of many people - why the windows are open 24 hours a day in winter, put a winter, and it still smells so big when you move in, this is because the indoor temperature is too low and formaldehyde does not volatilize at all.

1. The temperature suitable for formaldehyde volatilization is 19.

2. The boiling point of formaldehyde is 19. Each increase of one degree, the volatilization will increase, the average will reach 20%, as long as the temperature is higher than its boiling point is suitable for the temperature of formaldehyde volatilization, but the higher the temperature, the faster the volatilization rate of formaldehyde, and the higher the concentration.

3. The temperature is relatively low in autumn and winter. The decomposition and volatilization of free formaldehyde in wood-based panels is relatively small, and there is rarely the phenomenon of exceeding the standard, if the detection exceeds the standard at this time, it means that the indoor formaldehyde will exceed the standard more seriously in summer or when the indoor temperature exceeds 23. For every 1 increase in temperature, the indoor formaldehyde concentration increases by 12-13%.

In summer, when the temperature exceeds 30 degrees Celsius, the release of formaldehyde will show an explosive increase.

The above is an introduction to the content of what is the temperature suitable for formaldehyde volatilization.

The optimal temperature for formaldehyde volatilization is minus 35 degrees Celsius and the humidity is 80% humidity.

Under the condition of constant humidity, the release of formaldehyde is enhanced with the increase of temperature and humidity, and the formaldehyde concentration of the sample rises to about twice of the original for every 5 increase in the blindness of the closed air temperature car, and in the high temperature (35) environment, the increase of humidity makes the release of formaldehyde more intense. The relationship between temperature and humidity and formaldehyde release, formaldehyde release in summer is higher than that in winter, and formaldehyde content in humid environment is higher than that in dry environment.

Effective ways to remove formaldehyde:

Maintaining ventilation is the simplest and most effective way to remove formaldehyde, and in the case of air circulation, it can effectively reduce the formaldehyde content in the room. However, we will inevitably encounter the situation that we cannot open the window in our lives, so we cannot rely on ventilation alone, and it is best to use it together in combination with some other methods, so as to achieve uninterrupted formaldehyde removal and achieve the purpose of rapid formaldehyde removal; The respiration capacity of plants is quite limited, and it is at the level of micrograms (parts per million grams) of formaldehyde, and it has little actual effect on removing formaldehyde. <>

Generally above 19 degrees, formaldehyde is volatile in a high temperature environment, if the indoor formaldehyde exceeds the standard, we can use some heating equipment to accelerate the volatilization of formaldehyde, and then release formaldehyde by opening windows for ventilation, but using heating equipment, you must be careful to avoid fire and other risks, and then introduce some methods for you to remove formaldehyde, so that you can efficiently remove formaldehyde.

1. Open the window ventilation can quickly discharge the free formaldehyde to the outdoors, as long as the local air quality is up to standard, no other pollutants will be introduced, and it is easy to use and low cost, but it needs to be insisted on for a long time, because the release life of formaldehyde is long, and it is easy to repeat the situation when the ventilation is not smooth.

2. Activated carbon is a traditional physical adsorption material, which has been well received in the treatment of indoor and outdoor pollution, its specific surface area is large, and it has a strong adsorption capacity, but its adsorption capacity is limited, and it does not have the function of decomposition.

5. The blades of the fan can cut the air to promote the airflow in the process of rotating, so as to realize the replacement of indoor and outdoor air, accelerate the discharge of formaldehyde-containing air, and effectively reduce the concentration of indoor pollutants, but it can only treat the symptoms but not the root cause, and this method may not be practical in the warm season.

6. We all know that formaldehyde is volatile at high temperature, and we can use some heating equipment to increase the temperature at home a lot, so that a large amount of formaldehyde gas can be volatilized, and then formaldehyde can be removed by opening windows for ventilation. Repeated operation a few times, you can remove most of the formaldehyde in the home, but we must pay attention to safety when using heating equipment to avoid fire

If the ventilation is done well, it will take at least 2-3 months for the renovated house to move in. It is recommended that you buy a formaldehyde test box or formaldehyde tester to detect the formaldehyde content. The following are suitable for human habitation.

The above instructions exceed the standard, and measures to remove formaldehyde need to be taken as soon as possible.
