How to reduce formaldehyde pollution in winter? How to remove formaldehyde in winter?

The arrival of winter not only brings people snow-covered scenery, but also brings sorrow to people, why? Because formaldehyde has not stopped! We all know that formaldehyde will volatilize when heated, and its boiling point is 19 degrees, and in winter, because of the help of geothermal heat, heating, etc., it is not surprising that the indoor temperature reaches this degree, therefore, reducing formaldehyde pollution is also a major problem.

Since we want to eliminate formaldehyde pollution, we must first know where formaldehyde comes from. The main ** is the glue and surface paint used in furniture; Radon pollution mainly comes from natural stone and concrete. These two pollutants will be slowly emitted from furniture and building materials, and the release period can be as long as 315 years.

Not only that, formaldehyde is also very harmful to human health, if people live in an environment with excessive formaldehyde for a long time, it may cause throat discomfort, eye stinging, allergies, nausea, vomiting and other symptoms, and in severe cases, it will even cause cancer.

Since formaldehyde is so harmful to the human body, how can we reduce formaldehyde pollution?

To reduce formaldehyde pollution, the main way is to use less glue, and try to purchase solid wood furniture and use less panel furniture. Because formaldehyde mostly comes from flooring, particleboard, plastic products, etc., it is better to pay attention to choosing furniture samples that have been placed in an open space for a long time when purchasing. In addition, the use of environmentally friendly materials and environmentally friendly paint during decoration can effectively reduce the release of formaldehyde pollution.

Seeing this, some friends who have finished decorating may be in a hurry, I have finished decorating, what should I do? You can't disassemble and reinstall it, right? Don't worry, there is also a way to achieve the purpose of removing aldehydes after decoration.

Method 1: Plant absorption method. Plants have a certain ability to absorb formaldehyde, such as cacti, spider plant, reed, ivy, iron tree, chrysanthemum, etc.

Generally speaking, large foliage and vanilla plants have a better effect of absorbing formaldehyde, such as spider plant, tiger tail orchid, etc., which can not only remove formaldehyde, but also decorate the indoor environment, but the plant adsorption capacity is limited, can only be used as an auxiliary means, relatively speaking, it is more suitable for those who have mood and time to try.

Method 2: Solid activated carbon has the characteristics of many pores, has a strong adsorption and decomposition effect on formaldehyde and other harmful substances, placed in the renovated room, will improve the air in the room, the smaller the particles of activated carbon, the better the adsorption effect. It should be noted that the service life of activated carbon is short, and it will reach a saturated state in 2 or 3 months, so it is necessary to replace new carbon bags regularly.

Method 3: The principle of formaldehyde removal of Maya blue is similar to that of activated carbon, which is mainly based on adsorption. The difference is that its composition contains a high-sensitivity photocatalyst, which can decompose most of the pollutants while adsorbing pollution, and can maintain 85% of the formaldehyde removal effect even if it is used for three years.

If you can't do the above two methods, then this method is undoubtedly the most worry-free!

1. Put salt water in the new house.

Taking advantage of the water-soluble property of formaldehyde, you can put a few basins of water in each room, so that you can initially absorb a large number of pungent odors in the room.

2. Indoor ventilation.

Formaldehyde is a volatile substance, which can be used to open the doors and windows of the room to maintain air convection indoors and outdoors. In this way, about 2 months can effectively remove formaldehyde at home.

3. Activated carbon, tea water, etc.

There are a few things that can be used to improve indoor air quality with odor adsorption. At present, activated carbon is the most commonly used. Placing about 50g of activated carbon per square meter can play a good role in the adsorption of formaldehyde, but at the same time, it is also necessary to pay attention to the replacement of activated carbon, which is generally appropriate once every 7 to 8 months.

In addition, tea water, grapefruit peel, onion slices, white vinegar, etc. also have an adsorption effect on formaldehyde.

Formaldehyde is harmful to the human body, especially in the winter season, there is a large amount of formaldehyde in the air, so how to remove formaldehyde efficiently, there are mainly the following 4 methods:

1. Open windows frequently for ventilation

2. Plant plants

Plants have a relatively strong ability to absorb formaldehyde, if you can grow some plants at home, such as cactus, spider plant, aloe vera, iron tree. Chrysanthemums, etc., these plants can have a good absorption of formaldehyde and can help purify the air. Of course, if the formaldehyde contained in some air is too high, it is also easy to cause the death of plants.

So try to choose better plants to absorb formaldehyde, such as large-leaf and vanilla plants, which have a good effect, such as tiger tail orchid.

3. Activated carbon adsorption method

Solid activated carbon has a unique point with many pores, and has a strong adsorption and decomposition effect on harmful substances such as formaldehyde. Of course, the smaller the particles of activated carbon, the better the adsorption effect tends to be. Mainly according to the size of the space, the placement is different, and the amount is different, so the adsorption effect is different.

Select a certain amount of adsorption and then replace it, so the effect is very good.

4. Select a purifier

At present, the classification of air purifiers on the market is relatively wide, such as negative ion type, ozone type, filter adsorption type, electrostatic integrated type, etc. Different air purifiers work in different ways. But if you want an air purifier to work better, you often need to choose a more multi-functional one.

It is very good to have these tools to help remove formaldehyde from the air every day, and for the sake of good health, you can also eat more foods that remove waste toxins from the body, such as black fungus, kelp, etc., which is very good.

Many friends of the new house do not have such a feeling, that is, there is a large odor in the interior after the decoration of the new house, especially after the new furniture is bought and assembled and placed, this smell will be more intense. Many people will classify this odor as formaldehyde and other harmful gases, and various formaldehyde removal methods are also used. Among them, the window ventilation method recognized by the majority of friends to remove formaldehyde odor is the most effective, no matter how much formaldehyde concentration is in the room, how big the decoration odor is, is there formaldehyde in the smell?

As long as good air circulation is maintained after ventilation, it will have an immediate effect. However, now that it is a cold winter, some families in northern cities are simply unable to achieve long-lasting ventilation every day, which leads to indoor formaldehyde and other harmful gases and pungent odors cannot be effectively discharged, and the more they accumulate.

In addition to formaldehyde, the company first talked about activated carbon, and after the decoration of the new house, some carbon bags in all the furniture can indeed play the role of adsorbing formaldehyde and peculiar smell, but the carbon bag adsorption will also be saturated, once it reaches the saturated state, it will be re-released outward, which may produce secondary pollution. The indoor air purifier filtration method, everyone must know that the biggest function of the purifier is to filter small particles such as small particles, but the filtration effect of formaldehyde, a harmful gas and odor, can be said to be minimal.

The above traditional indoor methods of removing formaldehyde and odor have been refuted, is there no better and more effective way? The answer is that this efficient aldehyde removal method certainly exists, depending on whether you can trust it. It has been proposed that professional work to find a professional Tianjin formaldehyde removal company or personnel to do, especially like the new house to remove formaldehyde to remove odor this complex and time-consuming work, can be directly entrusted to the professional Tianjin formaldehyde removal company to deal with, they generally have efficient products and advanced construction technology, can be effectively used through the technical means of decomposition and catalysis to the root of those polluting gases, which will not only reduce the release of formaldehyde, but also a large number of odor removal and alleviation, with the help of professional formaldehyde removal companies, You don't have to worry about this kind of work anymore.

In daily life, formaldehyde is ubiquitous, it can be said that every family will have different concentrations of formaldehyde pollution indoors after decoration. Formaldehyde treatment indoors after the decoration of the new house is the primary project of many families before moving in, and due to the problem of not being able to open the window in winter, many owners have made it difficult to remove aldehyde in winter.

1. 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 formaldehyde gas can volatilize in large quantities, 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.

2. 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. Activated carbon to remove formaldehyde is the most commonly used way to remove formaldehyde in life, and the cost is low, but activated carbon is prone to adsorption saturation in a short period of time, and it needs to be replaced or dried after saturation. Another point to note is that if the amount of activated carbon is not enough, it will not play much role in removing formaldehyde indoors.

6. Professional formaldehyde removal companies can also quickly remove indoor formaldehyde and harmful substances, but because China's indoor air purification industry started late, there are no particularly strict scientific specifications, in the formaldehyde removal company, there are many unprofessional and irresponsible companies, we must keep our eyes open when choosing

First, open more windows for ventilation. The ventilation method is the easiest way to remove formaldehyde. Experiments have proved that 30% of free formaldehyde molecules can be removed by opening windows for ventilation for more than six months.

In winter, the weather is cold and windy, and everyone may be reluctant to open the windows for ventilation, in fact, this is not right. In winter, the indoor temperature rises, the formaldehyde release is active, and the air is not circulated, which will increase the indoor formaldehyde content sharply. Therefore, it is also necessary to open the window for ventilation in winter, especially for the new house that has just moved in, you must insist on opening the window for ventilation for more than 2 hours every day, and 9 o'clock in the morning - 12 o'clock in the morning is the most suitable time to open the window for ventilation.

Second, use activated carbon to remove formaldehyde products. Activated carbon to remove formaldehyde is to use its own countless tiny pores to adsorb harmful gases such as formaldehyde and benzene. In addition, it should also be noted that when choosing this kind of product, you must choose products with vacuum packaging, and do not choose those flashy decorations, because too much contact with air before use has greatly reduced the formaldehyde removal effect of this type of product.

Third, install exhaust fans, especially in sealed spaces such as bathrooms, and turn on more exhaust fans at ordinary times.

Method 1 of removing formaldehyde in winter: open windows for ventilation.

To remove formaldehyde and other odors in a newly renovated house, the first step is to open the windows for ventilation, as well as open all the furniture that will produce odors, such as opening the cabinet doors, opening the drawers, and opening the kitchen cabinet doors and drawers to make them fully breathable and fully dissipate formaldehyde and odors. In winter, it is rare to see windy and rainy weather, so you don't have to worry too much about the wind and rain damaging the furniture, just pay a little attention to the weather.

Note: In fact, in winter, the weather temperature is low, the wind is small, and the convection is not strong, so the effect of using the method of opening windows for ventilation in winter is not as good as that used in summer.

Method 2 for removing formaldehyde in winter: activated carbon.

Under the condition of opening windows for ventilation, due to the low air temperature, the enthusiasm of furniture to emit formaldehyde is not high, so activated carbon can also be placed to absorb formaldehyde through activated carbon, which is also a good method. Pay attention to the outer packaging of activated carbon, it is best to open it, the effect will be more obvious.

Method 3 to remove formaldehyde in winter: place plants.

In the newly renovated room, a lot of plants are placed to absorb formaldehyde, which is a method that everyone will think of, such as pothos, tiger pill orchid, spider plant, etc., and the effect is better than the adsorption effect of activated carbon. In particular, it should be pointed out that the bamboo itself does not have the effect of removing formaldehyde, but it can judge the quality of the air, so after removing formaldehyde for a period of time, you can put a few pots of bamboo at home when you want to live, and see its survival.

Method 4 to remove formaldehyde in winter: turn on the heating.

There is floor heating in the north, air conditioning in the south, and the new house that has just been renovated can turn on these heating, because the boiling point of formaldehyde is 19 degrees, the higher the temperature, the faster the formaldehyde volatilizes, but in winter, the scattered formaldehyde is defeated at this temperature, and can only rely on the "artificial" temperature to emit formaldehyde. Open two-fist-wide seams for doors and windows to dissipate formaldehyde. This method consumes more power, so use it with caution.

Note: Although this consumes electricity, it is not the best way to remove formaldehyde in winter, and it is recommended to turn on the heating equipment (floor heating, air conditioning, oil tin, etc.), raise the indoor temperature, turn on the heating for one day, and ventilate for another day.

Method 5 to remove formaldehyde in winter: air purifier.

At present, the more popular air purifier on the market can remove formaldehyde, but according to professionals, the filter inside the purifier cannot remove formaldehyde, a small molecule of chemicals, so its main function is dust removal, generally in the early stage of decoration, it is not recommended to use an air purifier to remove formaldehyde, but it can be used to remove dust in the later stage, which is convenient to move in.
