Formaldehyde is ventilated for several hours a day

Many people mistakenly think that opening windows and ventilation can remove formaldehyde, in fact, formaldehyde is very stubborn, some inferior decoration materials, formaldehyde release life may be as long as more than ten years, formaldehyde long-term contact with the human body will be harmful to health, so the treatment of formaldehyde must not have a fluke mentality, the following is for you to introduce some aldehyde removal tips, so that you can control formaldehyde within the safety range as soon as possible.

1. Wise Stone.

It is a very popular purification product on the market in recent years, the main reason is that it has the dual function of absorption and decomposition, can actively absorb free formaldehyde in the air, and does not have to worry about the influence of external factors such as temperature, humidity, light, etc. The adsorbed formaldehyde will also be decomposed into water and carbon dioxide and discharged from the body, without drying and no secondary pollution. When choosing, it is important to note that it is a gray ore with an irregular shape and is not a round particle.

2. Open windows for ventilation.

If you want to remove 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.

3. Plants.

Plants can remove formaldehyde, although formaldehyde can be removed, but the amount of formaldehyde it absorbs is very limited, and when the indoor concentration is high, if the plant alone relies on formaldehyde adsorption, the amount is very large.

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, high temperature.

In the case of high temperature, it can promote the conversion of formaldehyde in the bound state into free formaldehyde and reduce the total content of formaldehyde, because formaldehyde penetrates deep into the board, although formaldehyde cannot be completely removed, but its effect is still very obvious

Formaldehyde, as a colorless and toxic gas, if exposed to it for a long time, will seriously affect people's health, and even suffer from respiratory diseases, and can also cause allergic rhinitis and pigmentation, so it is necessary to remove formaldehyde before moving into a new house, and it is recommended to carry out a variety of methods at the same time.

According to the actual situation, it can be opened for a longer time if the weather is clear, and it can be opened shorter on the contrary, and there are no strict regulations.

It may take about half a year of ventilation to completely dissipate, and if a child wants to live in such a home, it may need ventilation for a year before it completely dissipates.

It takes at least half a year for formaldehyde to dissipate, and if you are not in a hurry to live, you can place it for a year, so as to reduce the harm of formaldehyde to the body.

It takes half a year to put some pothos in the house, and you should have frequent ventilation in your life to remove formaldehyde, and you can also buy some activated carbon.

After many friends decorate and decorate, the first thing that comes to mind should be to open the window for ventilation. However, if you want to achieve the effect of removing formaldehyde through ventilation, you need to meet the following conditions:

First, the wind speed is strong enough.

Indoor and outdoor air are replaced, and the wind displaces indoor formaldehyde and other harmful gases to the outdoors through flow, which requires the wind speed during ventilation to reach a certain degree, if the wind speed can not meet the requirements of indoor air replacement, there is no way to discharge indoor formaldehyde into the room. In many cases, the wind speed does not meet the requirements for indoor air replacement, resulting in poor ventilation in addition to formaldehyde.

2. Maintain long-term ventilation.

Ventilation to remove formaldehyde requires long-term indoor ventilation, but it is difficult to maintain long-term ventilation in the actual living environment. In the summer, it is not possible to maintain long-term ventilation, because the air conditioner is often turned on and the windows must be closed. And ventilation is only in the state of open windows, in order to keep warm in winter, many people are closed windows, in general, depending on the weather conditions to determine whether to ventilate, ventilation in addition to formaldehyde is only to temporarily reduce the formaldehyde content in the city, and formaldehyde has been volatile.

Once the formaldehyde removal company did such an experiment, the indoor formaldehyde after ventilation is milligrams per cubic meter.

After continuously sealing the doors and windows for 12 hours, the concentration of formaldehyde in the room was measured in milligrams per cubic meter. This shows that once the indoor air is not circulated, formaldehyde will accumulate again and exceed the standard, and formaldehyde can not be solved by only a few months of ventilation.

3. Unable to open the cabinet door for a long time.

Everyone knows that a very important part of indoor formaldehyde treatment is because too much glue is used in the process of making furniture, cabinets, etc., resulting in continuous formaldehyde emissions and causing harm to the human body; In the process of normal use, all cabinet furniture drawers cannot be opened, which will directly affect the ventilation effect.

Fourth, formaldehyde emitting time is long.

According to the research of the formaldehyde removal company, the formaldehyde release time of indoor furniture is about 5-15 years. Even if ventilation is maintained, it is impossible to maintain it for many years. Formaldehyde release is long-term and uninterrupted, formaldehyde content may decline under ventilation conditions, but once the window is closed, the formaldehyde content will rise rapidly, we sleep, turn on the air conditioning, the weather is cold, etc., can not maintain ventilation, will make the formaldehyde content in the indoor air increase rapidly.

It takes 3 to 15 years for formaldehyde in furniture to be released. After renovation, it is generally necessary to open the windows for ventilation for at least a few months before the newly renovated house can be moved in. Formaldehyde cannot be removed quickly. The easiest way to do this is to open the windows for ventilation.

The indoor formaldehyde content is closely related to the use time, ventilation conditions, temperature and relative humidity of the room. The longer the house is used, the higher the temperature and the lower the humidity, the more conducive to the release of formaldehyde.

Formaldehyde treatment method for window ventilation.

Natural ventilation is one of the most commonly used methods to remove formaldehyde in people's daily life. The effect of formaldehyde treatment is also obvious. However, the method of removing formaldehyde from ventilation has certain requirements for the air volume and wind quality of the natural wind, that is, it needs to be low pollution.

Fresh air. Because window ventilation does disperse formaldehyde, but this is only temporary, and formaldehyde-containing substances will continue to volatilize. When the window is opened, the indoor formaldehyde content will temporarily decrease, and when the window is closed, the indoor formaldehyde will gradually increase.

Therefore, although window ventilation is the most economical and practical way to remove formaldehyde, this method is greatly affected by environmental factors. The use of this method needs to pay attention to environmental factors and should be adapted to local conditions, rather than blindly being regarded as a "magic formula for aldehyde elimination, a panacea"!

The use of activated carbon and window ventilation to remove formaldehyde is easy to have cognitive misunderstandings!

Activated carbon adsorbs formaldehyde.

The removal of formaldehyde by activated carbon adsorption is achieved through the interaction between the adsorbent and the adsorbent molecule. Most of the commonly used adsorbents are porous materials, such as silica gel, bamboo charcoal, activated carbon, activated alumina, zeolite molecular sieve, etc.

Let's take activated charcoal as an example, a kind of activated carbon the size of a grain of rice, if you peel off its pores one by one, you can cover a room of 30 square meters. Natural charcoal has such properties after deep processing. Due to the large specific surface area of carbon ions, they can be in full contact with air molecules.

During contact, these voids can intercept these formaldehyde molecules, allowing formaldehyde to enter them. Especially between air and air molecules, there is mutual attraction, that is, mutual attraction between air molecules. Only in this way can activated carbon have good adsorption properties.

The experimental results showed that the concentration of formaldehyde decreased significantly after the activated carbon was passed through the activated carbon, indicating that the activated carbon could adsorb formaldehyde. However, as the experiment continued, the formaldehyde emission curve from the formaldehyde generator to the activated carbon also changed significantly. After 4 hours, the concentration of formaldehyde increased significantly, indicating that after the ability of activated carbon to purify formaldehyde reached saturation, it would no longer adsorb formaldehyde, and may even cause secondary pollution.

Therefore, the disadvantages of activated carbon adsorption are also very obvious. When the activated carbon adsorption of formaldehyde is saturated, it is difficult to adsorb new formaldehyde. If the ambient temperature rises, the formaldehyde molecules that have been adsorbed may volatilize again, causing the indoor environment to be polluted again.

The formaldehyde volatilization period is as long as three to fifteen years, and it takes at least two summers to rely on ventilation alone.

Interior decoration materials and furniture, especially glue and paint, contain the most formaldehyde. Formaldehyde is volatile, not that you treat it once, as long as the furniture and decoration materials are still indoors, formaldehyde will continue to volatilize, and the amount can only be smaller and smaller. Generally speaking, but zero formaldehyde is impossible, the formaldehyde volatilization cycle is 3-10 years, the better the material used, the lower the formaldehyde content, the worse the material, the higher the content, the reliable method or more ventilation.

If the indoor formaldehyde exceeds the standard, or if you are in a hurry to move in, it is recommended to choose professional products for comprehensive treatment, and you can generally reach the standard in about seven days.

If the car removes formaldehyde, the ventilation time will not be too long, generally 2-3 months is about the same, and you can choose a photophyll material to decompose it. Indoors, ventilation should be at least half a year; If you want to remove formaldehyde quickly, you need to use some methods:

1. Water mixed with vinegar in the car can play a role in stabilizing formaldehyde.

2. Herbs: Extracted with some herbaceous plants.

3. Use some alcoidan and activated carbon into the car for adsorption, in addition to adsorption of materials that can also be decomposed.

4. Open windows for ventilation at ordinary times. If you can park in a safe place, open the doors and windows when not in use.

For ventilation and formaldehyde, it needs to be treated differently, different periods, different seasons and different weather have different treatment methods, not one-size-fits-all, and you can sit back and relax when you keep opening the window. Correct ventilation to remove formaldehyde

High temperature and humidity in summer, which is conducive to the release of indoor formaldehyde pollution, is the best period to remove formaldehydeIt is sufficient to keep it ventilated at all times

Spring and autumn weather, the temperature is not high at night, it can be adoptedThis is a method of sealing the room temperature during the day and opening the window for ventilation at night

Winters are lowNorthregionThere is heatingYou can choose fromClosed at night and ventilated during the daySouthNo heatingRegion canChoose an air conditioner or heaterHeat up the room to speed up formaldehyde release, and thenMethods of ventilation

4. For the house type with poor ventilation, the method of direct blowing of a large wind fan to increase indoor air circulation can be used to cooperate with ventilation.

Ventilation to remove formaldehyde is a more effective way to remove formaldehyde, it is characterized by the immediate effect when the window is opened, and the formaldehyde release cycle is as long as 3-15 years, only by ventilation to remove formaldehyde, not only the effect can not be fully guaranteed and the time cost will be relatively high, so in the daily formaldehyde removal process, ventilation is a necessary condition, but can not be completely relied on, with some other methods used together, the effect will be faster and more guaranteed.

In the high temperature in summer, is the stuffy ventilation really better than the ordinary ventilation?

As temperatures continue to rise, summer is approaching. Generally speaking, high temperature and humidity in summer are particularly conducive to the release and emission of formaldehyde, and it is the best season of the year to remove formaldehyde. But do you really know how to ventilate in the summer?

Especially on the Internet, is the smoldering method ventilation really better than ordinary ventilation?

We all know that high temperature and high humidity help to accelerate the release and emission of formaldehyde, so the suffocation method has been recognized by many people, but in fact, it is not as you think, the measured data proves: when the formaldehyde concentration reaches a certain amount, formaldehyde is no longer released or the release amount is very small, which happens to be contrary to the suffocation method, so the significance of stuffiness is not very large, and the actual effect is not as fast as ventilation all the time.

Summer is a good time to remove formaldehyde, but the speed of formaldehyde removal in new houses is still too slow to speed up formaldehyde purification, and we can also cooperate with the following methods to achieve better and faster results.

1. Fan with ventilation

For poorly ventilated houses or rooms, fans can be used to accelerate indoor air circulation, and at the same time, open the furniture doors and drawers as much as possible, which is conducive to the dissipation of pollutants in the furniture and can achieve better and faster ventilation effects.

2. Formaldehyde is removed by algae

It can play a role in adsorbing and decomposing formaldehyde, three years of sun-free, do not worry about adsorption saturation, put it at home at all, it is more suitable for urgent use, and it will be more convenient to use without drying.

3. Activated carbon absorbs formaldehyde

In the case of sufficient use of charcoal bag, the purification effect is still good, but its adsorption capacity is certain, and we must remember to dry and replace it in time during use, so as to avoid the problem of adsorption saturation, which is more suitable for light pollution and not in a hurry to move in.

4. Auxiliary purification of green plants

Many green plants have the effect of purifying the air, such as: pothos, spider plant, yew, etc. are all with a certain adsorption and purification effect, placed in all corners of the house, not only can play a role in purifying indoor air, but also can beautify the living environment, is also a good choice.
