Is there a lot of formaldehyde in sofas? Do sofas contain formaldehyde?

Sofas have a high formaldehyde content. The formaldehyde on the sofa mainly comes from the products that have formaldehyde components used when the sofa is welded to the frame, and there are many filling substances in the sofa, which will also contain formaldehyde, so the formaldehyde content in the new sofa is still very high.

Sofas contain a lot of formaldehyde, mainly in the following three aspects:

First, the frame of the sofa.

If the frame of artificial sheets is used on the sofa, there is a risk of formaldehyde contamination, and it is also a deep formaldehyde pollution that is easy to ignore and hide. It's usually hard for people to notice. However, the artificial board is deeply wrapped in the sofa, and a large amount of free formaldehyde in the artificial board volatilizes for 3-15 years, which will cause harm to human health.

Second, the padding of the sofa.

The filling of the sofa will not only affect the service life and comfort of the sofa, but also affect the health of the human body. In fact, the reason is that during the production process of sofas, the internal padding is easily contaminated by volatile substances such as formaldehyde.

Third, the material of the sofa.

1. Fabric sofa. Formaldehyde is widely used in the textile industry, and there is also a hidden danger of formaldehyde due to the purchase of textiles for sofas. In order to make the fabric anti-wrinkle, anti-shrinkage, and flame retardant, the manufacturer will add formaldehyde to the auxiliary.

2. Leather sofa. It gives it a sense of nobility and magnificence, but it is also very harmful. It is understood that leather processing needs to go through tanning, dyeing, spraying and fixing agent and other processes, and there will be formaldehyde and other air pollution dyeing.

It's not formaldehyde, it's the chemicals used to treat the leather.

Removal method: 1. Deodorization method of cleaning agent. Scrub the surface of the sofa with a clean cotton cloth or cotton ball dipped in detergent.

Commonly used cleaning materials are: a mixture of ammonia, alcohol and water; Weakly alkaline cleaning agents; Dedicated leather cleaner. For some leather coats that do not smell too strong, the first two types of cleaning materials can be used, which are cheap and easy to obtain.

For some leather clothes with strong odor, it is best to choose some leather cleaning agents with better effect, but the cost is higher.

2. Hanging and drying to remove odor. Place the sofa in a dry, ventilated shade to blow away odors. When hanging the leather clothes, you can spray a little vinegar on the clothes, the vinegar will not taste after drying, and the odor will be reduced or even disappeared.

3. Grapefruit peel deodorization method. Wrap the skin of 2-3 yuzu in the sofa and leave it for about a week to remove odors and smell the fragrance of yuzu. You can also put a few grapefruit peels or some activated charcoal in the cabinet where the leather clothes are placed to absorb odors.

Sofas contain formaldehyde, which adsorbs on the surface of the material.

Formaldehyde is water-soluble, so we need to clean the sofa cover regularly, and dry and ventilate it after cleaning, which can effectively reduce the formaldehyde content. It can also be moved outside for sunlight and ventilation.

The main raw materials of the sofa are chemical fibers, cotton, linen and light industrial textiles blended fabrics, in the printing and dyeing, embryo making, insect and mildew prevention, etc., formaldehyde and DMF are used as industrial raw materials to achieve the effect of insect prevention, moth prevention and mildew prevention. Formaldehyde is generally added to the production of textiles. Therefore, in the field of home clothing, soft decoration materials include curtains, bedspreads, pillowcases, sofa covers, etc.

The padding of the sofa is mainly sponge and fluffy cotton. The sofa cushion should be a whole sponge, but some merchants sometimes use broken sponges and other "black cotton" for profit, and then plug them with glue. Therefore, when consumers buy a sofa, they must ask about the padding in the sofa, and if there is a zipper that can be opened to see, it is best to take a look and smell it.

Yes, the new sofa I just bought must have formaldehyde.

Most sofas use a variety of chemicals, such as adhesives, in the production process.

additives, paints, etc. The sponge in the sofa will also use some glue for connection, and the direct glue also has a certain formaldehyde content. There are also some sofas that will use wood-based panels as material frames, as we all know that the material version contains formaldehyde, so most of the sofas made of it will have formaldehyde and other polluting substances.

Formaldehyde is mainly found in glues, adhesives and the like. If the sofa you buy is not made of solid wood, but multi-layer boards, there is a possibility of formaldehyde. Formaldehyde-containing chemicals may also be used in leather treatment.

There will definitely be, both sponges and wood structural adhesives will be present.

Look at what material, it's best to open the window for ventilation after you buy it.

The formaldehyde content of leather sofas is not high. The main reason is that formaldehyde is not easy to volatilize after being wrapped inside, so the pollution caused by leather sofas is mainly due to the use of a large amount of glue in inferior leather, and the glue contains a large amount of formaldehyde and benzene, so the leather sofa that uses a lot of glue will also be one of the formaldehyde.

Leather sofa maintenance knowledge:

1. Ensure ventilation in the living room: pay attention to ventilation for the maintenance of leather sofas, and leather sofas can not be exposed to the sun, nor can they be placed in places where air conditioning blows directly, which is easy to fade or harden.

2. Do not use soapy water and other cleaning: Do not use soapy water or detergent to clean the leather sofa, because they have a certain degree of corrosiveness and are easy to damage the surface of the leather sofa. In addition, many leather sofas nowadays are fiberboard.

If the machine is pressed, if there is moisture penetrating into it, it will not become moldy in the first two years because the formaldehyde and other additives have not been completely volatilized. However, once the additives have evaporated, the moisture of the damp cloth can cause mold to the furniture.

3. Don't rub vigorously: you can't use too much force when scrubbing the leather sofa, now there are many materials of the leather sofa, and the maintenance methods of different materials are different, therefore, when cleaning, you should use a dry cotton cloth for regular cleaning, do not scrub the surface of the leather sofa too hard, avoid scratching the surface, peeling, and it is best to put it in a dry and ventilated place.

Sofa is the most common in furniture, many sofas on the market are made of wood-based panels, resulting in high formaldehyde content, which will cause health damage to the human body, such as: Leather sofa: general leather sofa needs to be tanned, dyed, fixed and similar and sprayed to make of process, there will be formaldehyde and other harmful substances pollution, and formaldehyde is not easy to volatilize in the "package", long-term adsorption will cause harm to the body, such as dermatitis, redness and swelling, and in severe cases, it can lead to death.

Fabric sofas: Fabric sofas, while easy to clean, easy to maintain, are cheap, and beautiful and so on. However, fabric sofas are generally made of padding, and the quality of the padding and adhesive leads to the presence of a large amount of formaldehyde.

In addition, in addition to formaldehyde, the company found that most of the wooden frames of fabric furniture are wood-based panels, so there will also be formaldehyde molecules.

Rattan sofa: The traditional rattan sofa uses natural tree plants, but with the forest resources and environmental protection, the cost of solid wood sawn timber is high, and some popular brands of rattan sofas are made of composite panels, which contain formaldehyde molecules.

At the same time, a large amount of glue is used in the production process of the sofa, and the glue contains a large amount of formaldehyde and benzene. Therefore, there must be formaldehyde pollution in sofas. Newly bought sofas usually contain formaldehyde, but regardless of the formaldehyde content of the sofa, it is necessary to properly dispose of the formaldehyde of the sofa to avoid harming the body of the family.

At the same time, formaldehyde is released slowly and will last for several years.

1.If you buy a new sofa, it is recommended that you do not put it in the bedroom right away. It is best to place it in a well-ventilated place to accelerate the release of formaldehyde concentrations. It is best to use it after 1-2 weeks of ventilation.

2.When buying sofas, choosing wooden panels or materials with high sealing degree produced by big brands can reduce the harm of harmful substances to the human body. At the same time, the quality of the materials used to make the sofa is also relatively guaranteed.

In addition, it is best to ask the merchant for instructions on the use of furniture, understand the content of formaldehyde, and reduce the damage of formaldehyde to the human body.

3.In removing formaldehyde from the sofa, some measures can also be taken to effectively remove it, such as activated carbon is placed under the sofa and porously adsorbs formaldehyde slits; Placing green plants, such as spider plant, tiger tail orchid, ivy, aloe vera, agave, pothos, etc., can not only beautify the home environment but also help formaldehyde adsorption a part, although the adsorption capacity is weak, but there is better than nothing.

4.To hire a professional formaldehyde removal company for governance, it is best to choose a qualified institution, such as whether there is a business license and the governance qualification of the formaldehyde license. Because they have professional formaldehyde removal technology, such as using high-temperature fumigation liquid to quickly release formaldehyde from the pollution source, formaldehyde can be removed from the source.

Therefore, after buying a new sofa, friends can remove formaldehyde through the above four methods to ensure that the sofa and other furniture will not cause harm to the human body. In addition, the house must also have windows and ventilation regularly to maintain indoor air circulation, which accelerates the release of formaldehyde and ensures healthy indoor air quality.

Sofas and other newly bought furniture will generally have formaldehyde, even solid wood furniture can not guarantee zero formaldehyde, in the case of uncertainty, it is best to do an aldehyde removal test, once it is found that formaldehyde exceeds the standard must be treated, because long-term contact with formaldehyde is harmful to human health, so do not have a fluke mentality towards formaldehyde, the following is an introduction to several methods of removing aldehyde, I hope you can quickly control formaldehyde within a safe range.

1. Wise Stone.

It can actively adsorb indoor free formaldehyde, the process will not be affected by any external factors such as temperature, humidity, light, etc., 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. Plants.

Choose plants that can adsorb formaldehyde, pothos, aloe vera, spider plant and other plants can adsorb a certain amount of formaldehyde pollution, and can indeed remove formaldehyde. Placing some greenery in your new home can also help to beautify the room and freshen the air. However, the adsorption capacity of plants is relatively limited, and if the formaldehyde concentration is too high, the plants will wilt and die.

3. Open windows for ventilation.

If you want to remove formaldehyde and odor as soon as possible, the first thing to do is to open the window for ventilation, open the cabinet doors and drawers at the same time, and dilute and discharge the formaldehyde to the outside through air convection. Although this step is simple, it is also necessary to pay attention to the weather conditions, so as not to break the newly renovated home environment with strong wind and rain

Fourth, photocatalysts.

Photocatalyst is a product that can decompose formaldehyde into carbon dioxide and water through light or ultraviolet irradiation, which can be effective for a long time at one time, but its requirements for action are relatively high, and the effect is not particularly obvious, so it is recommended as an auxiliary method when used.

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.

The most complete furniture odor removal method in history, there is always one suitable for your home1. Furniture ventilation

Ventilation should not only open the doors and windows, but also the furniture doors, so that the odor in the furniture can be emitted as soon as possible, which can be of great help to reduce the odor of furniture.

2. Sun exposure

Under the premise that the conditions permit and do not damage the furniture, the furniture can be exposed to the sun, and the high temperature exposure can accelerate the release rate and amount of pollutants in the furniture, which is helpful for accelerating the emission of furniture odors.

3. Soil method to remove odor

Onions, grapefruit peels, tea, vinegar smoking and other soil methods are also used by many people, but after many verifications, the real effect of these deodorization methods is really general, most of them are smell masks, and can not play a true role in purification.

4. Carbon bag adsorption

Activated carbon bag is a more commonly used adsorption material, and placing some activated carbon bags in and around the furniture can play a good role in adsorption and purification, but here we need to remind everyone that the adsorption capacity of carbon bags is a certain amount, and it must be dried and replaced regularly to avoid the problem of adsorption saturation.

5. Remove the smell of algae

The difference between it and activated carbon is that it not only has a better adsorption effect, but also adds a double group of decomposition components, which can automatically adsorb and decompose harmful gases, so it is sun-free, and there is no need to worry about adsorption saturation and secondary pollution, in comparison, it will be more convenient to use, and the speed of purification will be faster.

6. Decomposition medium spraying

Spraying the inside and outside of furniture with a decomposition medium can form a decomposition layer, which has a very good effect on removing the odor of furniture, but the decomposition medium must choose pure natural ingredients.

7. Wipe with salt water

Formaldehyde and other harmful substances are soluble in salt water, and wiping furniture with mild salt water can effectively take away some of the harmful substances attached to the surface of furniture, which can also play a good role in reducing the odor of furniture.

8. Green plants absorb odors

Placing green plants with air purification functions such as pothos, spider plants, and yew in and around the furniture can not only play a good role in purifying the air, but also beautify the living environment, which is also a good choice.

Conclusion: These are the more popular furniture odor removal methods on the market, the effect is different, the method also has its own characteristics, you can choose the most appropriate method according to the actual situation of your own home, but we still have to remind you that these methods are supplemented, the most important thing is to try to choose furniture and plates with high environmental protection coefficient, and try to avoid excessive decoration and decoration, so as to reduce pollution from the source.
