What causes such a high concentration of formaldehyde in the summer indoors?

The indoor formaldehyde and other harmful gas concentrations will be very high after the new house has just been renovated, especially in the summer high temperature period, the indoor formaldehyde concentration will be higher, and the indoor formaldehyde concentration is about 2-3 times that of other seasons, so what will cause such a high concentration of indoor formaldehyde in summer? Let's talk about this reason!

First of all, the formaldehyde in the pollution sources such as decoration materials and furniture will continue to volatilize into the indoor air, as long as the indoor temperature is higher than 19 degrees, the formaldehyde at the source of these pollution sources will volatilize in large quantities, when the temperature is higher then the volatilization rate of formaldehyde will be faster, when the indoor temperature is in the range of 19-22 degrees Celsius, the volatilization rate of formaldehyde is quite gentle, once the temperature exceeds 25 degrees Celsius, the volatilization rate of formaldehyde will increase rapidly. When the indoor temperature rises by every degree Celsius, the rate of formaldehyde volatilization will increase by about double, and the indoor temperature in summer can generally reach about 30 degrees Celsius, which is the main reason for the high indoor formaldehyde concentration in summer.

Secondly, in the summer high temperature this time period, people in order to prevent heatstroke and cool down will turn on the air conditioning to live or work indoors, the premise of the air conditioning is that the indoor doors and windows need to be closed, so that the formaldehyde emitted by the pollution sources of decoration materials and furniture to the indoor is more difficult to diffuse, which will also lead to higher indoor formaldehyde concentration, and the indoor humidity will also rise after the air conditioner is turned on, and the indoor formaldehyde concentration will naturally increase when the indoor humidity rises. In addition, some bacteria will grow inside the air conditioner after long-term use, so that the human body is prone to tonsillitis and pneumonia after inhalation.

Finally, we should use environmentally friendly decoration materials when decorating a new house, but environmental protection materials do not mean that there is no formaldehyde at all, but the formaldehyde release in environmental protection materials will be smaller, so you can not always close the windows when you turn on the air conditioner in summer to escape the heat, but to open the window for ventilation in the morning, noon and evening, so as to reduce the indoor formaldehyde concentration as much as possible, if there are children or pregnant women at home, you can not take this risk!

Because the temperature in summer is relatively high, and the indoor ventilation is not strong, which makes it difficult to dissipate formaldehyde, I think it is better for tenants not to move in at this time.

The main reason is that the temperature is too high, the formaldehyde volatilization is incomplete, and secondly, it is also because some inferior products are used in the decoration, so this situation will occur.

High temperatures, without good ventilation, will lead to an increase in formaldehyde, which will diffuse when the temperature is very high.

In the summer, we will obviously feel that there are some peculiar smells indoors for no reason, and even stay at home there will be spicy eyes or throat discomfort and other physical reactions, which are actually caused by formaldehyde, summer happens to be the most rampant season of indoor formaldehyde volatilization, so we should guard against indoor air pollution in summer, especially to prevent formaldehyde as a harmful gas, in the four seasons of the year, the amount of formaldehyde released in different seasons is relatively large. The probability of indoor formaldehyde exceeding the standard in winter is relatively low only about 10%, and the probability of indoor formaldehyde exceeding the standard in spring and autumn is about 30%, but the probability of indoor formaldehyde exceeding the standard during the high temperature period in summer will be as high as 80% or more, which shows that the temperature is the main reason for affecting the indoor formaldehyde concentration, and then let's talk about the topic of high temperature release of formaldehyde!

First of all, in the summer, the indoor temperature is generally very high, which leads to the acceleration of the volatilization of formaldehyde in the decoration materials and furniture, that is, the formaldehyde inside these pollution sources will be transferred to the indoor air, the usual season formaldehyde is slowly transferred, and the formaldehyde will accelerate the transfer when it comes to high temperatures, and the indoor humidity in the summer time period will also rise, because formaldehyde is very easy to dissolve in water, at this time, there will be a lot of formaldehyde in the water molecules in the air. This can also directly lead to the increase of indoor formaldehyde concentration.

Secondly, the volatilization point of formaldehyde is at 19 degrees Celsius, and the indoor temperature in summer can generally reach more than 25 degrees Celsius, when the indoor temperature rises by every degree Celsius, then the speed of these pollution sources to the indoor volatilization of formaldehyde will increase by about double, when the indoor temperature rises to 30 degrees Celsius, and the indoor humidity reaches 50 percent, then even if the original indoor formaldehyde does not exceed the standard, the indoor formaldehyde concentration will reach about milligrams per cubic meter. If the indoor temperature is as high as 35 degrees Celsius, the indoor formaldehyde concentration will be doubled, because the release rate of formaldehyde has doubled, of course, the rate of formaldehyde release is affected by factors such as air pressure in addition to temperature and humidity.

Finally, the materials used in the decoration of each household are different, so the indoor formaldehyde concentration is also different, the more luxurious the decoration will be used in the materials, then the indoor formaldehyde concentration will be higher, mainly caused by the effect of superimposed release of formaldehyde, so environmental protection materials do not represent environmental protection decoration!

Yes. In the hot weather in summer, everyone should pay attention to ventilation and often open doors and windows for ventilation.

Yes, because when the temperature is high, some formaldehyde can be released better, so the concentration will also increase.

Formaldehyde has two characteristics, one is that the volatilization point is at 19, and the higher the temperature, the more intense the volatilization; Another point is that the incubation period is as long as 3-15 years, two properties that make formaldehyde a "stubborn molecule" of air pollution. The volatile point of formaldehyde is 19, and the concentration rises twice for every degree of temperature rise, especially in spring and summer, when the temperature rises and the release is more intense, and the concentration will exceed 3 times of normal. When the heating makes the indoor temperature rise, they will be released, and the formaldehyde concentration will be released faster with the increase in temperature, so summer is the high season for indoor formaldehyde exceedance!

The release of formaldehyde in newly renovated houses is very high, and the release cycle of formaldehyde is as long as 3-15 years, so it is difficult to clean up for a period of time, especially in winter when the ventilation is not smooth, it is easy to exceed the formaldehyde standard, so we must choose the correct and effective aldehyde removal method.

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.

Putting some green plants at home can also effectively remove odors, especially pothos, spider plants, aloe vera, monstera, cactus, ivy, etc., which can effectively absorb harmful gases. In addition, large plants such as the Ping An tree and the camphor tree, which are more popular on the market, can release a fresh gas on their own, which makes people feel happy, and is also more suitable for removing the smell of new furniture

3. 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.

Fourth, activated carbon.

Using activated charcoal is also a great option. The surface of activated carbon is rich in pores, which can adsorb indoor odors, and also has a certain effect on pollution control, but the activated carbon treatment capacity is limited, and it will produce saturation after about half a month of use, and it is impossible to continue to work.

5. Formaldehyde remover.

There are many principles of formaldehyde scavengers, there are formaldehyde decomposition, formaldehyde is closed, the former is only the free formaldehyde is decomposed, the bonded formaldehyde inside the material is still in the continuous decomposition and release, the latter is the use of protective film to isolate formaldehyde from the air, formaldehyde still exists, when the protective film is broken, formaldehyde will still gush out in large quantities!

Formaldehyde is a high-ranking toxic substance, but also a potential carcinogen, before moving into a new house to remove formaldehyde is an urgent job, according to the above, you can choose a variety of methods at the same time.

Because the doors and windows are basically closed in winter, and the air conditioner and floor heating will be turned on, as the temperature rises, the release rate of formaldehyde will also increase exponentially, so the formaldehyde concentration per unit area will definitely become higher.

Because the indoor heating temperature is high in winter, the concentration of the price will increase with the temperature all of a sudden, so we should put more green plants and pothos in the house.

In winter, the temperature is low, the formaldehyde volatilization is slow, and if the formaldehyde concentration will become high, it must be related to the fact that you do not open the window for ventilation.

Because the windows are not opened in winter, and there is heating in the house. The increase in indoor temperature will make the formaldehyde concentration increase all of a sudden. So be sure to ventilate more.

In this case, because the air pressure is low in winter, and the doors and windows are basically closed, there is a lack of ventilation, and of course the concentration is high.

Because the temperature is not so high, the gas volatilization rate slows down, and formaldehyde will continue to be released, I hope it can help you.

The main reason is that the temperature is low, the air is not circulated, and the speed of circulation is also slow, so the formaldehyde concentration will become high.

Because of the winter indoors
