Is it effective to remove formaldehyde using the heating method

Void. Rising air temperatures, air humidity.

Increasing, the pollution of home decoration has also entered a high incidence period. When the room temperature rises, the formaldehyde volatilized in wood products, floors, etc., will increase the formaldehyde concentration in the indoor air, and most of the other pollutants have similar characteristics. Therefore, many rooms that pass the inspection in winter may fail the inspection when the temperature is high.

Many citizens like spider plants and tiger tail orchids.

Green plants such as aloe vera and cactus are placed at home to purify formaldehyde, but in fact, the absorption of formaldehyde by plants can only play an auxiliary role in the whole process of purifying the air, because plants are through photosynthesis.

The surrounding formaldehyde is consumed, so the absorption efficiency will be low at night and on rainy days, which also reduces the absorption efficiency of plants to formaldehyde.

Not so good. The first is to open the windows for ventilation. The principle couldn't be simpler, it is to blow the air and replace the air.

When the air is replaced, so are the pollutants. Just like feeling cold after a few minutes of opening a window in winter, your pollutants and warm air are quickly replaced by the air outside. However, a quick replacement does not mean that the new home can be moved in one day with the windows open.

The second major type of method is activated carbon adsorption. Activated carbon adsorption is really great, but it should be replaced regularly The third major method is photocatalysis. Taiwanese call it photocatalyst. This method is only applicable to formaldehyde and is not useful for aromatic hydrocarbons. Because formaldehyde is easily oxidized.

The fourth broad category of methods is thermal catalysis. Manganese dioxide is used in the general active center. At room temperature, manganese dioxide directly catalyzes the oxidation of formaldehyde into formic acid, which is non-carcinogenic and has low toxicity.

The problem is that if formic acid accumulates too much, it becomes inactive. Therefore, this technology is generally also used in air purifiers, and generally intermittently, the air purifier will heat to more than sixty or seventy degrees to further oxidize formic acid into non-toxic carbon dioxide.

Heating can not remove formaldehyde, so that formaldehyde is completely released, and some measures are still needed to remove formaldehyde.

1. Keeping windows open for ventilation is a simple, practical and cost-effective method.

2. Herb removal method, herbal plant liquid removal, direct decomposition of pollution sources, plant herb refining.

Third, the placement of green plants here has to say that the power of nature is unlimited, although plants can adsorb formaldehyde, but the adsorption capacity of plants is limited, and it is not realistic to rely on plants to remove formaldehyde alone. It can only play an auxiliary role. You can put some activated carbon and leaf wide mud materials to adsorb and decompose formaldehyde.

Heating can release formaldehyde faster, and the higher the temperature, the more active the formaldehyde release. Formaldehyde is released and can be absorbed and decomposed with some products:

1. After ventilation, the use of some Yeguang mud activated carbon can dilute formaldehyde, and remember to keep ventilation at home. Ye Guang mud is with adsorption.

2. Use cyclokang dealdehyde enzyme to decompose in the house and furniture.

3. You can also wipe the furniture with salt water to remove the smell.

1. Activated carbon, a material that can be adsorbed, a good number of Ye Guang mud, this kind of material can be placed in the car at home, used for 3 years, and can be used for light pollution.

2. Plants and plant liquid, plants are generally used more is spider plant, aloe vera, moso bamboo, these plants adsorption is relatively slow, decomposition is the plant liquid extracted from these plants Diarin, you can use the decomposition of formaldehyde and new house taste.

3. If you are not in a hurry, you can ventilate during this time, and ventilation can discharge the harmful gases released.

4. Photocatalyst, this kind of product is a chemical product, and the choice of nano aldehyde removal enzyme material with better material has a good effect on the new house, and it can be decomposed without ultraviolet rays.

Formaldehyde is generally released faster when the temperature reaches more than 25.

The boiling point of formaldehyde is 19 degrees Celsius, that is, when the temperature exceeds 19 degrees Celsius, the higher the temperature, the faster the formaldehyde hidden in the room will volatilize. It is reported that when the indoor temperature rises by 1, the volatilization rate of formaldehyde doubles. This is also why in summer, or when heating in winter, formaldehyde in new houses is more likely to exceed the standard.

Based on this attribute, summer has also become the best time to remove formaldehyde. Because summer is in the high temperature period, the room temperature is generally high, at this time, a large amount of formaldehyde hidden in the new house will be released. When the indoor temperature reaches more than 25, formaldehyde will volatilize faster.

Other factors that affect formaldehyde release

1. Humidity: humidity is an important factor affecting the release of formaldehyde, if the home is very humid, it will increase the volatilization of formaldehyde, formaldehyde and urea catalyze the formation of urea-formaldehyde resin under the chemical reaction, and urea-formaldehyde resin is mostly used in many places of our interior decoration, such as floors, storage cabinets, etc., if the room is humid, urea-formaldehyde resin will decompose into urea and formaldehyde, so that formaldehyde is released, so a large basin of water is placed indoors for the absorption of formaldehyde effect is also good.

2. Air flow: The premise of air flow is to open the window, but it is not only to open the window, the air flow is required, then the formaldehyde release will be more, and the formaldehyde discharged to the outside will be more, which is more effective for the removal of formaldehyde, because the density of formaldehyde is heavier than that of air, and it is generally floating below.

3. Release source: Many places in our room contain formaldehyde, and the amount of formaldehyde contained in different materials is different, and the volatilization time is also different. Generally, it takes about a week to half a month for wall paint to evaporate, wallpaper takes at least 1 year, large core board is 1 year to 5 years, and some man-made boards can not be volatilized even for 15 years.

Formaldehyde will be released faster and faster after 19 degrees, if the indoor formaldehyde exceeds the standard, we can use some heating equipment to accelerate the volatilization of formaldehyde, and then release formaldehyde by opening windows for ventilation, but using heating equipment, we must be careful to avoid risks such as fire, and the following will introduce some methods for you to remove formaldehyde, so that you can efficiently remove formaldehyde.

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. 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. Open windows for ventilation.

Open the window ventilation is the best way to remove free formaldehyde, when the window is opened, there will be a steady stream of fresh air will dilute the indoor air containing formaldehyde to achieve the purpose of purifying formaldehyde, but the window is easily affected by the weather, and the effect is also affected by the house type when used.

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, the fresh air system.

The fresh air system is similar to the ventilation method of removing formaldehyde, but there is no need to open the window when in use, and the air delivered to the room is filtered, and it is also used when it exceeds the standard.

Formaldehyde in indoor decoration pollution is mainly in indoor decoration materials, of which harmful substances account for a large proportion of latex paint, paint, wallpaper and other wall coatings, so it is very important to deal with formaldehyde from the source.

Formaldehyde can be removed at high temperature, but it cannot be removed directly, because high temperature has a good volatilization of formaldehyde, formaldehyde produces faster thermal movement at high temperature, so that formaldehyde can be emitted faster in the pollution source, so as to achieve the purpose of removing formaldehyde.

Other effective ways to remove formaldehyde:

Open window ventilation is a long-term effective way to remove formaldehyde, but also does not require any monetary cost, open window ventilation can be used to ventilate other indoor through the wind, etc., so as to achieve the purpose of formaldehyde removal, but it is difficult to solve formaldehyde pollution from the root.

Nowadays, most families are equipped with 2-3 negative ion air purifiers, which can quickly purify the polluting gas within a fixed range in a very short time, and formaldehyde can also be well purified, because the use area is limited, so it needs to be configured with a few more units to have an effect.

The effective removal of formaldehyde is to invite a professional formaldehyde removal company, they use professional agents, professional equipment, and professional team personnel, which can treat formaldehyde to a greater extent and remove formaldehyde for a longer time.

High temperature is only conducive to formaldehyde volatilization, if the amount of formaldehyde is certain, there is no more volatilization, and formaldehyde can be removed. For example, after the newly renovated wall paint, wallpaper, glass glue, styrofoam, the amount of formaldehyde contained in it is certain, and there is no more after volatilization, and high temperature is an effective means to remove formaldehyde in these materials.

Even if there is no high temperature, the formaldehyde in these materials will be basically released in 2 weeks to 3 months, and the amount of formaldehyde is small, and the pollution to the air is relatively light. High temperature helps to accelerate the release and volatilization of formaldehyde, especially in summer, high temperature and ventilation help to volatilize formaldehyde in materials such as wall paint as soon as possible.

The formaldehyde that cannot be removed at high temperature is the formaldehyde in the man-made panel. The formaldehyde in the wood-based panel is produced due to the moisture decomposition of urea-formaldehyde glue, and the high temperature can only promote the volatilization of formaldehyde produced by decomposition, but when the urea-formaldehyde glue is damp again, it will decompose and produce new formaldehyde, and in a period of up to 3-15 years, the moisture decomposition process of urea-formaldehyde glue will continue. Therefore, high temperature cannot remove formaldehyde pollution from furniture wood-based panels.

In order to remove the formaldehyde pollution of the wood-based panel of furniture, it is necessary to use the "formaldehyde scavenger of the wood-based panel" to treat the wood-based panel furniture in order to remove the long-term formaldehyde pollution in the room.

Melting point -92, boiling point. Soluble in water and ethanol. The concentration of aqueous solution can reach up to 55%, generally 35%-40%, usually 37%, called formaldehyde water, free formaldehyde is the best treatment, high temperature will promote the adsorption of formaldehyde and the conversion of combined formaldehyde into strong formaldehyde, which is conducive to volatilization.

1. Ventilation method:This way of removing formaldehyde is to discharge more harmful gases such as formaldehyde out of the outdoors through air circulation. Although this method of removing formaldehyde is simple and suitable to operate, it generally takes 3 or more than 3 years to completely remove formaldehyde, which is not feasible for Qiaosui to be used in ordinary families.

2. Use formaldehyde scavenger or formaldehyde lytic enzymeFormaldehyde cleaning agent removes formaldehyde by chemical methods to reduce the toxicity of formaldehyde or convert it into a non-toxic substance; Formaldehyde dissolving enzyme removes formaldehyde by infiltrating this enzyme into the board material to remove harmful gases, but it still cannot achieve complete removal.

3. Activated carbon adsorptionThis method is used to form an adsorption formula by the gravitational pull of the carbon molecules in the activated carbon with the adsorbed molecules.

4. Air purifier:An air purifier can take away toxic substances from the air, making the indoor air relatively fresher.

1. Ventilation. The simplest and most commonly used way to remove formaldehyde is ventilation, after the decoration of the new house, open the doors and windows to ensure air circulation, which can timely let the formaldehyde and other harmful gases precipitated from the room drift to the outdoors, this method is not only low cost, but also saves worry and effort.

2. Plants. Some plants can not only adsorb harmful gases such as formaldehyde, but also convert formaldehyde into harmless substances through a ability similar to that of photosynthetic allergens. For example, common pothos, spider plant, aloe vera, etc., these plants can not only adsorb formaldehyde, but also add more green land for the new home.

3. Activated carbon.

The internal structure of activated carbon has many pores, and these pore structures can well adsorb free formaldehyde and other harmful substances in the air, but it should be noted that there are several kinds of activated carbon, including chitin, wood and coal, etc.

4. Diatom mud.

Diatom mud is a kind of wall decoration material, which has the same developed pore structure as activated carbon, and its porosity is higher, which can reach 80% 95%, and its adsorption capacity is better than that of activated carbon. Moreover, some diatom mud products will add photocatalyst, which can convert formaldehyde into a non-toxic substance under the action of ultraviolet rays. In addition, diatom mud also has the effect of regulating indoor humidity, fire retardant, air purification, etc., and is a very environmentally friendly and healthy decoration material.

5. Formaldehyde scavenger.

The chemical principles of formaldehyde scavenger products on the market are generally nothing more than 4 kinds: neutralization, catalytic decomposition, blocking and blocking, and redox. Some formaldehyde scavengers are sprayed directly on the board, and some are sprayed in the air, consumers can match the two types of formaldehyde scavengers according to their own needs, and the aldehyde removal effect is better, which is simple to use, and the effect is also good.

6. Purifier.

Some air purifiers on the market also have the effect of adsorbing formaldehyde, and its principle is similar to that of air conditioners, mainly because the filter element in the purifier plays the main adsorption role. However, the quality of the filter element in the air purifier is good and bad, so pay attention to check it when purchasing. In addition, the filter element of the air purifier needs to be replaced, and the cost of use is high.
