Is it okay if there is formaldehyde ventilation indoors?

Some people say that there is formaldehyde on ventilation, although ventilation is conducive to the release of formaldehyde, but ventilation alone can not remove indoor formaldehyde, and the temperature and humidity are different, ventilation is also particular, such as in winter, try not to open the window at night, will destroy the furniture.

If you want to use ventilation to remove formaldehyde, you should do it after the formaldehyde release reaches saturation, such as adjusting the temperature and humidity of the room upwards, and sealing the room, when the formaldehyde release reaches a certain level, and then ventilation, you can achieve a good aldehyde removal effect.

You can also buy a few fans during the day, and the fan with a larger area blows the air indoors, so that the indoor air forms a convection, which can achieve a good effect on the removal of formaldehyde.

Finally, I would like to remind everyone that it is best to use some environmentally friendly materials when decorating, and the interior decoration should be streamlined, and there should not be too many decorations, so as not to cause excessive formaldehyde and affect health.

Opening windows for ventilation can make indoor air circulate better, thereby reducing the concentration of toxic gases in the room. But opening windows for ventilation does not solve this problem at the source. In a poorly ventilated room, the formaldehyde concentration still does not decrease.

In the case of bad weather, it is useless to open the windows for ventilation. And now the outdoor air pollution is also more serious, the outdoor is also relatively high, and the ventilation of the window can achieve the desired effect. The window cannot be opened at any time, so the ventilation of the window cannot solve all the problems in the room.

Ventilation can only disperse free formaldehyde, but the formaldehyde in the furniture will be continuously released, and the formaldehyde concentration will increase after you close the doors and windows, and the release cycle of formaldehyde is as long as 15 years, so ventilation alone is not enough.

Frequent ventilation is still beneficial, and it is also a more practical way to remove formaldehyde. If the formaldehyde is seriously exceeded, it is better to find a professional to deal with it.

It is best to ventilate for more than half a year, formaldehyde is colorless and odorless, if it is only a short ventilation, formaldehyde has not been completely dispersed, it is easy to formaldehyde poisoning, which is very harmful to the body.

First of all, we need to affirm the temporary effect of ventilation in removing formaldehyde.

High-efficiency ventilation has two conditions at the same time, one is to open the window, and the other is to have a large wind speed. If these two conditions are satisfied, then the efficiency of ventilation to remove formaldehyde is very high, and even the indoor formaldehyde concentration will approach 0 within a few minutes.

Secondly, we need to understand that most of the time in our lives the efficiency of ventilation is not high.

In real life, it is certainly not very windy 24 hours a day, and in many cases it will be stuffy, and the wind speed is not strong enough, and the efficiency of formaldehyde removal will be low. In addition, the ventilation conditions of many homes are not very good, the windows are small, or they are relatively leeward, so the ventilation efficiency is also very poor.

Again, we have to be clear that the release period of formaldehyde is very long, and formaldehyde will accumulate again when the window is closed.

The release period of formaldehyde is as long as 3-15 years, and it cannot be released in a short period of time. Therefore, it is easy to remove formaldehyde by ventilation method, even if it is up to standard, as long as the window is closed (such as sleeping at night, rainy days, windy days, etc.), indoor formaldehyde will accumulate again until it exceeds the standard again.

In addition, we also need to know that formaldehyde detection is to be tested after 12 hours of closed room.

Under the state of ventilation, most of the indoor formaldehyde in the family is up to standard, there is no doubt about this, because formaldehyde will not stay at home under air flow, and it is basically up to standard. But the problem is that the safe formaldehyde concentration cubic meter is to be tested after closing the doors and windows for 12 hours. This excludes the role of ventilation, so the ventilation method removes formaldehyde, and the time to reach the occupancy standard is very long, even if it meets the standard, it is very easy.

Finally, the second question in the next title: How long does it take to ventilate before moving in?

There is no fixed answer to this question in the industry, because the excessive size of formaldehyde in each family is different, and the house structure, furniture placement, how much furniture, and the quality of decoration materials are different in each family, so how long it takes to ventilate to meet the formaldehyde standards is also different.

In addition to ventilation, you can also place some green plants with the effect of removing formaldehyde indoors, and it is understood that green plants have a relatively good effect of purifying the air.

Buy some good quality white vinegar, place it in the corner of the room, and change it every ten days, this method can play a certain auxiliary role in removing formaldehyde.

Ventilation is a simple and effective way to remove formaldehyde, open the window to let the indoor and outdoor air circulate, which is conducive to the release and dissipation of decoration pollution, pollution is not accumulated indoors, the pollution of the new house will naturally be much less, and ventilation is the basis of formaldehyde, any method needs to be used together with ventilation to achieve better results.

It can also be used with the following 3 methods to remove formaldehyde.

1. Decomposition medium spraying.

Furniture and other plates are one of the main indoor pollution, and pollutants are inside the board, only by natural dissipation, it takes a long time, so the fastest and most direct method is to penetrate the inside for purification, the use of algae spray on furniture plates, etc., can penetrate and induce the decomposition of formaldehyde, which is of great help to accelerate purification and shorten the purification cycle.

2. Physical decomposition.

Compared with the carbon bag, the speed of adsorption and purification is faster, and it can play a role in decomposing formaldehyde, which does not need to be dried regularly, and there will be no problem of adsorption saturation, which is more suitable for urgent use, and does not need to be dried without worrying about adsorption saturation, and it will be more convenient and convenient to use.

3. Air purifier.

Ventilation is greatly affected by the weather and environment, when the weather is bad or there is no way to open the window at night, you can use it with an air purifier appropriately, so that you can achieve 24-hour uninterrupted ventilation and purification, and it is also a good choice to use it.

Of course. The most effective way to remove formaldehyde.

The volatile point of formaldehyde is 19 degrees Celsius, so when the room temperature is lower than 19 degrees Celsius, formaldehyde does not volatilize in large quantities. Therefore, it is necessary to actively create a high-temperature environment. For every 1 degree Celsius increase in temperature, formaldehyde concentrations multiple.

You can turn on floor heating or air conditioning and other equipment, close all doors and windows in the home, accelerate the release of formaldehyde, increase the indoor temperature, and wait until the temperature drops before opening all windows for ventilation, and repeat several times to effectively remove formaldehyde.

Activated carbon can rely on its well-developed pore structure and surface area, which can be exposed to the surrounding air to a large extent, and passively adsorb some pollutants into its own pores, so it is widely used to remove indoor formaldehyde. However, the adsorption capacity of activated carbon for formaldehyde is weak, and the adsorption will reach saturation. Moreover, after reaching saturation, it is easy to be affected by external factors, desorption, resulting in secondary pollution.

Ventilation can only emit formaldehyde, not remove formaldehyde, because formaldehyde is slowly emitted inside the object of home decoration, and nothing can go deep into the interior of the home decoration to remove formaldehyde.

But on the other hand, ventilation is the best way to remove formaldehyde from indoor air, which is much more reliable than some aldehyde removal sprays, air purifiers, etc.

Charge can remove formaldehyde, ventilation is the most direct and simple way to remove formaldehyde, generally after the house decoration to remove formaldehyde, generally open windows for ventilation, keep indoor air circulation, try to put the indoor formaldehyde smell to the outdoors. It is conducive to the volatilization of formaldehyde, so ventilation can remove formaldehyde.

Ventilation can remove formaldehyde, but it is only for the free state of formaldehyde, the interior of the decoration materials containing formaldehyde will continue to release formaldehyde from its interior, there are unforeseen circumstances, when the ventilation is not smooth, formaldehyde will soon exceed the standard, so in addition to ventilation, some other methods should be used.

Opening windows for ventilation helps with air circulation, but it does not completely remove formaldehyde.

After the decoration of the new house, the floor, wallpaper, and wardrobe will release formaldehyde, especially the inferior decoration materials, the release of formaldehyde will last for more than ten years, so how should we deal with formaldehyde? Here are a few ways to do it.

1. Wise Stone.

It can actively adsorb indoor free formaldehyde, permeability clearance will not be affected by any temperature, humidity, light and other external factors, the adsorption rate of formaldehyde is also dozens of times that of ordinary adsorption materials, in addition to the unique decomposition function, the adsorbed formaldehyde can be decomposed into harmless carbon dioxide and water, and then discharged, so that its internal pores have been in an unsaturated state, and the aldehyde removal rate can reach more than 90%. 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.

We all know that the easiest way to remove formaldehyde is to ventilate, the room ventilation is not in a good state of the family, through the fan to accelerate the indoor and outdoor air flow, accelerate the discharge of formaldehyde-containing air, can effectively reduce the indoor pollutant concentration, but it can only treat the symptoms can not cure the root cause, and this method may not be very practical in the season when you need to keep warm.

3. Plants.

The use of green plants to purify formaldehyde is a very promising way to remove aldehyde, plants will adsorb a part of the pre-formaldehyde during photosynthesis, but the absorption is extremely small, and it is recommended as an auxiliary method when removing formaldehyde.

Fourth, high temperature.

We all know that formaldehyde is volatile at high temperature, and we can use some heating equipment to increase the temperature of the 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.

5. Photocatalysts.

The main principle of photocatalyst is that the spray will adhere to the surface of the object to form a strong film, on the one hand, it will slow down the release of formaldehyde, on the other hand, it will contact with the film during the release process, and oxidize formaldehyde by using the photocatalytic performance of the photocatalyst. However, in daily life, the film may oxidize and wear, and the effect will be halved.

To sum up, as long as you choose the right method, it is not difficult to remove formaldehyde, but it is not possible to use a single method, we can use several methods to carry out it.
