When removing formaldehyde, is ventilation a panacea?

First of all, it needs to be affirmed that window ventilation can indeed be used to remove formaldehyde, because when the window is opened for ventilation, all the formaldehyde gas in the room can be discharged outdoors, so as to achieve air circulation. However, it has to be said that opening windows and ventilation has really little effect on formaldehyde removal. Formaldehyde is a very special gas with strong volatility, and the volatilization rate of formaldehyde will change with the change of high temperature.

That is to say, if it is in the hot summer, the formaldehyde concentration in the home will be very high, even if the window is opened for ventilation, it will have no effect, because if the window is opened, the indoor temperature will be higher, and the formaldehyde concentration will be higher.

In this case, formaldehyde cannot be effectively removed at all. Even if the window is open for three months, the formaldehyde concentration will still be very high. Ventilation is the universal rule.

It is necessary to ensure long-term ventilation, and it is best to ensure high temperature and humidity. Activated carbon, leaf wide mud. This material can effectively adsorb formaldehyde.

The latter can not only adsorb formaldehyde, but also decompose adsorbate, and is not easy to saturate. It is greatly improved on the basis of activated carbon. Green pigments.

I only learned this when I was doing the strategy: in fact, in addition to physical adsorption of formaldehyde, you can also take products that directly decompose formaldehyde, and the effect is faster.

Green pigment is a plant extract, sprayed on furniture, boards, walls, floors, can quickly decompose formaldehyde without damaging the contact surface. Green. Green plants do have the effect of purifying formaldehyde, but they are very small.

But it is also necessary to keep some green plants at home, and it is also very suitable for ornamentation, beautification of the environment, and regulation of humidity! In addition, it is said that some air purifiers have a certain aldehyde removal effect, but our outdoor air quality is okay, and I feel that it is not cost-effective to buy an air purifier.

It is true that ventilation can quickly remove formaldehyde from indoors. As long as all the windows in the home are opened, the formaldehyde in the indoor air will be blown out by the outdoor wind. However, if you want to blow out the formaldehyde in the room quickly, the premise is that there is wind.

We have to keep the indoor air convective so that we can blow out the formaldehyde quickly. If there is no convective wind, most of the formaldehyde in the room will still be blown around the indoor space. Only a small amount of formaldehyde can be blown outdoors.

To put it bluntly, a house with a north-south transparent pattern will have good convection winds. If the wind outside is not strong enough, we can put some electric fans at home to blow, which can also greatly improve the effect of ventilation and formaldehyde removal.

In addition to formaldehyde, although ventilation is not omnipotent, but very effective, you can also open the furniture doors, and then turn on the electric fan, you can also use activated carbon to adsorb and remove formaldehyde, but also through the way of green plants to remove formaldehyde.

I don't think ventilation is a panacea, because ventilation can't completely remove formaldehyde, formaldehyde is very tenacious, it exists in furniture, walls and floors, and it is best to use a special formaldehyde removal tool.

Ventilation can have a better effect on removing formaldehyde, but ventilation may cause some damage to the wall, and it may also cause the wall to crack.

I think that in addition to formaldehyde, ventilation is omnipotent, because ventilation can allow the released formaldehyde to flow outside, so that it will be safe to live.

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.

When the formaldehyde concentration is per cubic meter, it is almost tasteless, and will not pose a threat to human health, which is the standard set by the state, once it exceeds each cubic meter, the human body will feel uncomfortable, and will cause various diseases, when it reaches 30mg per cubic meter, it will cause cancer, and the harm to the human body is very great.

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.

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.

Some people think that after the decoration, there is no smell of ventilation, and it is enough to live in it. This is a big mistake, formaldehyde is colorless and odorless, it doesn't mean that the house is not, ventilation will temporarily produce formaldehyde in the room, but new furniture and decoration materials always contain the release of formaldehyde. Moreover, the release time is beyond imagination, the release period of formaldehyde is 3-15 years, and can't you always open the window?

Rain, wind, and many factors, so it is unrealistic to only ventilate and remove aldehydes.

We can use these tips to get moving.

Tip 1: Air purifier purification

The air purifier has a fan-like device and a built-in filter, which can filter the indoor air, and can replace the ventilation when the window cannot be opened for ventilation or at nightIt has a good effect on removing pollution in confined spaces, and when the ventilation conditions do not allow, the appropriate amount of use is still effective.

Tip 2: Wipe down furniture with salt water

The formaldehyde in the furniture plate will be slowly released through the surface of the furniture, and wiping the surface of the furniture with mild salt water can effectively take away the harmful substances attached to the surface of the furniture, and have a certain effect on removing the odor of the furnitureIf you have the time, wiping it down often can have a good deodorization effect.

Tip 3: Strongly decompose formaldehyde

Baizao Na adds a two-component decomposition component, which overcomes the technical drawbacks of a single component that requires light to work, and truly realizes itNo photodecomposition of formaldehyde, three years of sun-free, no need to dry during use and completely care, the design of the small bag is also very convenient to useIt is placed on the bottom of the bed, the bottom of the sofa, the cabinet and other formaldehyde pollution sources to continuously adsorb and decompose, which truly saves effort and worry.

Tip 4: Spray furniture

The algae spray is used for furniture pollution control, compared with ordinary formaldehyde scavengers, it is not only safe and non-toxic, and does not hurt furniture, andIt can penetrate the inside of the furniture panel, accelerate the decomposition of formaldehyde from the source, and the speed and effect of purification are faster and betterIn addition, it can be dried 1-2 hours after spraying, and the furniture can be used normally after drying, and the furniture can also be wiped at will, without affecting its function and not delaying daily life.

Ventilation is a commonly used method to remove formaldehyde, in the case of ensuring good air circulation, it is very effective in removing indoor free formaldehyde, if it is blown with an industrial fan, then the effect will be better.

However, formaldehyde has a long volatilization period, generally up to 3-15 years. Ventilation only removes formaldehyde free in the air, but the pollution source is still being released, so it takes a long time to remove formaldehyde more cleanly.

While ventilating to remove formaldehyde, it would be better to use other methods, such as:

1. Activated carbon adsorptionYou can put some activated carbon in each room, and its strong adsorption capacity can adsorb formaldehyde well and speed up the removal of free formaldehyde, as long as it is better on a regular basis.

2. Use fresh air system:The principle of aldehyde removal is similar to ventilation, and it can be used even in bad weather, but it needs to be installed when decorating.

3. Professional aldehyde removal institutions:The above method is mainly to remove free formaldehyde, and to find a professional formaldehyde removal agency is mainly to treat from the source of pollution, usually using photocatalyst and other technologies.
