Does newly bought furniture have to have formaldehyde?

The first thing to be sure of is that the newly bought furniture contains formaldehyde, even ifSolid wood furnitureIt also contains a small amount of formaldehyde.

Because furniture is mostly composed of wood-based panels, a large number of adhesives are used in the production process of wood-based panels and furniture assembly.

Among them, the high-quality and inexpensive urea-formaldehyde resin glue is the main one, which is the adhesiveFormaldehyde is released for up to 3-15 yearsIt is a long-term indoor release source and should be prevented.

Nowadays, some solid wood furniture will also use some adhesives in the production process, such as boards.

Adhesives will be used in the splicing parts, but it is true that the amount of glue used is much less than that of wood-based panels.

After the new furniture is delivered to the home, it is recommended to tear off all the plastic seals and throw them away, and place them near the window in a well-ventilated place to blow more, so that the formaldehyde near the surface can be released and volatilized as soon as possible. If it is fabric furniture, you can cover a layer of old sheets if you are worried about getting dirty, which protects the new furniture and does not affect the release of formaldehyde.

Newly bought furniture may contain a large number of harmful substances in the process of processing and manufacturing, and many of the harmful substances released by furniture can last for several years or even more than ten years, so we need to use some methods to remove formaldehyde and other harmful substances released from furniture, so as to ensure our health. 1. It is necessary to open all the cabinet doors and drawers of the furniture, so that the formaldehyde inside the furniture can be fully released, and at the same time, the windows should be opened to let the released formaldehyde out of the room with the help of wind, so that the formaldehyde in the furniture can be better released. 2. The adsorption of carbon bags, the most well-known method of this kind is activated carbon adsorption, activated carbon does have the effect of adsorbing formaldehyde, but activated carbon is easy to saturate, and it will be thrown away and replaced after about 10 days of use.

3. At present, most of the photocatalysts that we often mention are titanium dioxide, which can decompose formaldehyde into carbon dioxide and water through ultraviolet irradiation, but it needs to be involved in light and ultraviolet rays when working, and there are certain restrictions on formaldehyde removal for furniture, which can only be used as an auxiliary method. 4. Now the best formaldehyde removal product is Ruishi, which is a new generation of air purification products with pure natural mineral materials as the main component, with strong physical adsorption performance, which can effectively adsorb and decompose harmful gases in the air, easy to use, and can effectively control formaldehyde problems for a long time. 5. Air purifier Air purifier adopts a variety of purification technologies and purification mediums, which can adsorb formaldehyde and other decoration pollutants released by furniture, which can effectively improve indoor air quality and indoor air quality, but it will also be more expensive.

6. High temperature and drying can accelerate the volatilization of formaldehyde and other harmful substances, so you can take out drawers, movable furniture, mattresses, etc., to the balcony for ventilation and drying. It is recommended that high temperature promote the release of formaldehyde, so as to reduce the total content of formaldehyde in furniture, in the natural way to open the window ventilation + activated carbon + Ruishi to use, practical and healthy, activated carbon needs to be replaced regularly or taken to the outside for exposure to the outdoors when activated carbon is used, and the formaldehyde is released to the outdoors. Ruishi is a pure natural ore, not a man-made multi-colored particle, ** can be decomposed while adsorption, can be used for a long time, please look for the official website when buying!

Yes, under normal circumstances, newly bought furniture will have formaldehyde more or less, so in this case, the newly bought furniture must be placed indoors, ventilate and open the windows first, and then live after a period of time.

Not necessarily, pure solid wood furniture is formaldehyde-free.

Most of the newly bought furniture has formaldehyde.

Now due to the shortage of wood in China, there are man-made panels, and most of them use adhesives in processing and production, which produces chemical pollutants, such as formaldehyde, ammonia, etc., which will cause chemical pollution of indoor air. Unless the furniture is pure solid wood, there is no formaldehyde, as long as it is a man-made board.

The panels used in panel furniture or custom furniture mainly include particleboard, MDF, plywood and other man-made panels. The process of manufacturing this kind of board is simply to process the wood into sawdust, and then add adhesives, and through high-temperature extrusion, the wood chips are processed into boards. Formaldehyde is present in the adhesive.

Because formaldehyde has strong adhesion, it can strengthen the hardness of the board, prevent insects, prevent corrosion, and is cheap, so urea-formaldehyde resin with it as the main component is the raw material for various man-made plates.

Precautions: 1. In the man-made plate, the state has corresponding standards to treat. Generally, when buying these furniture, there is a label, in line with the national standards.

2. Formaldehyde is a volatile substance, as long as the room is well ventilated, the content of formaldehyde and benzene compounds will gradually decrease after a period of time, so the newly renovated family has purchased new furniture, it is best not to rush to move in, and let the harmful gases in the furniture be released as soon as possible.

New furniture generally has formaldehyde.

1. Formaldehyde is the main ingredient of glue, "no formaldehyde, no glue", as long as your furniture uses glue, it will contain formaldehyde. However, the amount of glue used in each furniture is different, and there is more formaldehyde used, like panel furniture, the amount of glue is very large, so the amount of formaldehyde produced will be a lot, and the amount of glue used in solid wood furniture is relatively much less.

Second, furniture will produce formaldehyde because formaldehyde is volatile, will continue to volatilize from the wood board or furniture, this is what we usually feel that some newly bought furniture will have a pungent or harsh smell, this is the formaldehyde volatilized from the furniture.

3. Methods for eliminating formaldehyde:

1. Activated carbon adsorption. Activated carbon to remove formaldehyde is a relatively cheap and practical method, characterized by physical adsorption, thorough adsorption, not easy to cause secondary pollution. The physical effect of activated carbon is deodorization and detoxification; There are no chemical additives and no effect on the human body.

Put two to three dishes in each room, and the indoor odor can be basically eliminated in 72 hours.

2. Plant deodorization method. The use of products with strong capture, adsorption and elimination of formaldehyde can effectively remove formaldehyde, ammonia, benzene, carbon monoxide and other harmful gases in the indoor environment. Not only for formaldehyde, it can effectively remove ammonia, benzene, TOVC and other harmful substances.

3. Ventilation method to remove formaldehyde. Through the circulation of indoor air, the content of harmful substances in indoor air can be reduced, thereby reducing the harm of such substances to the human body. In winter, people often close doors and windows, indoor and outdoor air can not circulate, not only the content of formaldehyde in indoor air will increase, radon will also continue to accumulate, and even reach a high concentration.

The smell of newly purchased furniture is pungent, not all of these furniture contain formaldehyde, and newly purchased furniture may also contain chemical agents, because the wood generally contains chemical agents when making furniture.

Most of the newly bought furniture has formaldehyde, as long as it is a man-made board, it will have formaldehyde, unless it is pure solid wood furniture. Now there is a shortage of wood in our country, and many furniture are made of wood-based panels, which will use a lot of adhesives when processing, which will produce harmful gases such as formaldehyde. Formaldehyde has strong adhesion, can strengthen the hardness of the board, anti-insect, anti-corrosion, and is cheap, so it is a raw material for various man-made boards.

How to remove formaldehyde from furniture? 1. Activated carbon adsorption method.

Place 3 to 5 plates of sufficient amount of activated carbon in every corner of the house. Using the physical adsorption characteristics of activated carbon, there is no chemical additives, it is not easy to cause secondary pollution, and it has no impact on the human body. However, it is only suitable for mild odor spaces, and it is saturated by itself, and once saturated, it will no longer adsorb.

2. Ventilation removal method: This is a more common method, open the doors and windows to make the air circulate naturally. This can reduce the content of indoor furniture odor to a certain extent, but it cannot fundamentally reduce the existence of harmful gases, cut off the source of pollution, and treat the symptoms but not the root cause.

3. Plant method: It is more appropriate to place 2-3 pots of plants with a height of meters in the room, and use the natural adsorption of the plants themselves. However, it is not possible to fundamentally reduce the presence of harmful gases and cut off the source of pollution.
