Does the sofa have formaldehyde pollution

Yes, furniture will have a bit of formaldehyde to some extent.

What is formaldehyde:

Formaldehyde, chemical formula HCHO or CH O, formula amount, also known as antaldehyde. Colorless gas, odorless, irritating to human eyes, nose, etc. Relative density of gases air = 1), density of liquids.

Melting point -92, boiling point. Soluble in water and ethanol. The concentration of the aqueous solution can reach up to 55%, usually 40%, called formaldehyde water, commonly known as formalin, is a colorless liquid with a pungent odor.

There is a strong reducing effect, especially in alkaline solutions. It can be burned, and the vapor and air form an explosive mixture, with an explosion limit of 7%-73% (volume). The ignition temperature is about 300 °C.

What are the hazards of formaldehyde:

The main harm of formaldehyde is the irritation of the skin and mucous membranes, and when formaldehyde reaches a certain concentration indoors, people will feel uncomfortable. Formaldehyde concentrations greater than those can cause eye redness, itchy eyes, throat discomfort or pain, hoarseness, sneezing, chest tightness, wheezing, dermatitis, etc. Newly renovated rooms have high levels of formaldehyde, which is a major cause of many diseases.

Why does sofas also have formaldehyde:

Some sofas have padding inside, and there is formaldehyde in these fillings, and some sofas have brush paint, and the paint also has formaldehyde. Formaldehyde mainly comes from urea-formaldehyde resin glue in wood-based panels, and the plates inside the sofa mostly exist under the sofa cushion, the back of the sofa and the armrests, etc., these plates are long-term release of formaldehyde, and the general release cycle is 3-15 years.

There is a treatment method for formaldehyde:

It is recommended to open more windows for ventilation, through the circulation of indoor air, the content of harmful substances in the indoor air can be reduced, 32313133353236313431303231363533e58685e5aeb931333363396335 so as to reduce 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. Buy activated charcoal and keep it in the house.

The smell of the new sofa is not all formaldehyde, but also TVOC total volatile organic compounds. A sofa usually consists of three parts: the frame, the padding, the fabric or the leather cover.

One: formaldehyde of the sofa frame.

The sofa will use man-made panels to make the frame of the sofa. Whereas, most sofa frames are made of wood-based panels. We know that wood-based panels, especially low-quality wood-based panels, are the main source of formaldehyde.

However, wood-based panels require an adhesive made from phenolic resin, which contains formaldehyde, to be pressed into shape.

Two: formaldehyde of sofa filling.

In the production process of sofas, the internal padding is easily contaminated by volatile substances such as formaldehyde. The padding of sofas is generally available in three types of down, rayon and sponge. Generally speaking, the padding of the sofa is a whole sponge, but there are also many cases where the sponges stick together (no formaldehyde, no glue), and some bad manufacturers use broken sponges to increase profits.

For example, black cotton and broken sponge are glued together. So, when buying a sofa, ask about the padding inside the sofa.

It's a good idea to check or smell for odors.

Three: formaldehyde from the sofa fabric or cortex.

There are also hidden dangers of formaldehyde in sofa production outsourcing. The manufacturer adds formaldehyde to the additives to make the fabric wrinkle-proof, shrink-proof and flame-retardant. After adding formaldehyde, the printing and dyeing is more durable and feels more comfortable.

In addition, the fabric cotton textile texture is soft and easy to wrinkle and deform. After using additives containing formaldehyde, pure cotton fabrics will be more brittle. Printing and counter-dyeing cannot be achieved with natural substances.

So the manufacturer will use some chemicals to complete it to meet people's demand for beautiful and fashionable cloth sofas. Leather processing needs to be tanned, dyed, sprayed and fixative, etc., and there will inevitably be formaldehyde and other dirt stains.

In addition to the formaldehyde of the sofa, ordinary ventilation does not work because the pollutants released by the sofa have penetrated into the padding of the sofa. The surface of the cloth sofa is a layer of cloth, so the formaldehyde material is emitted from the inside out, then the formaldehyde may be left on the cloth at this time, formaldehyde is soluble in water, so it is best to wash the sofa frequently, so that formaldehyde can be dissolved in water, and then dried in the sun. This reduces formaldehyde.

If you want to remove formaldehyde from the sofa! This matter still has to be handed over to professional formaldehyde removal products to manage!

Sofas are usually composed of three parts: frame, padding, and fabric upholstery. Normally, manufacturers use faux-based panels to create the frame of sofas, but man-made panels require an adhesive made of phenolic resin, which contains formaldehyde.

In addition, the fabric outsourcing of sofas also has formaldehyde hidden dangers. In order to make the fabric have the characteristics of wrinkle-proof, anti-shrinkage and flame retardant, manufacturers will add formaldehyde to the additives. Fabrics with added formaldehyde make the color of printing and dyeing more durable, and the feel is more comfortable.

In addition, the texture of cotton textile is soft, but easy to wrinkle and deform, after the use of additives containing formaldehyde, it can make the cotton fabric more structured. Therefore, the surface fabric of the sofa will also contain formaldehyde.

It is not terrible not to have formaldehyde, as long as you use professional products such as Shenguang aldehyde removal enzyme to treat it, you can reach the standard.

In order to fundamentally improve the level of pollution source control, it is necessary to carry out centralized supervision and treatment of the source to ensure that it does not cause serious effects on human health. In particular, it should be noted that in the decoration process, high-quality decoration materials should be selected to ensure that the formaldehyde content is controlled from the indoor source. In addition to formaldehyde, my household Shenguang aldehyde removal enzyme products are good, the wardrobe before treatment is inside, and the effect is very satisfactory after treatment!

At that time, I also saw on the TV news that it was developed by a college student, and it won the gold medal for invention, so I bought it and tried it, and there was no smell on the third day after use.

It depends on the material of the sofa. General design to wood (MDF), leather, etc. may have.

Formaldehyde is mainly emitted from the wood-based panels in the sofa frame, and has nothing to do with leather or cloth. Use a needle to inject water, such as formaldehyde remover, look at the introduction on the Internet, this water agent is recognized as the most practical and best effect in removing formaldehyde, although it is a little troublesome, but for the sake of health, the trouble point is not a problem.

Therefore, whether there is formaldehyde or not depends on the quality of the wood-based panels used. If the wood-based panel reaches the standard of E1 or E0, there is basically no formaldehyde pollution.

Yes, furniture or something is more or less smelly, so formaldehyde emission will be more, which is also normal. For testing, the most convenient and simple thing is to buy a formaldehyde test box for what to test, or you can find a professional company. Try to choose samples when choosing, this is placed for a long time and there is no more, or you can smell more when you buy it, if you have bought it back, put it away, and conditionally use some herbal dialin to decompose formaldehyde, which is no secondary pollution and no harm.

From the perspective of the materials used in the sofa, the formaldehyde itself will be relatively small, even if there is a small amount, because of its openness, volatilization will be faster.

If it is a cloth sofa, or there is padding in it, it is guaranteed to exceed the standard, and it is more troublesome to treat, which is also a big source of pollution.

When consumers buy fabric sofas, they must smell the smell first. If you feel tears or sneezing, it means that the formaldehyde content is high, and it is best not to buy it. After buying a fabric sofa, it is best to put it in a ventilated place so that formaldehyde can be released quickly.

If you have already purchased a sofa, be sure to wash the sofa cover regularly and dry it for ventilation. Formaldehyde is water-soluble, which can effectively reduce formaldehyde content.

Yes, because of the material of the sofa, it is inevitable that there will be this formaldehyde problem. Removing formaldehyde contamination from sofas can:

1. Ventilation, open windows for ventilation to keep the indoor air smooth.

2. Place some plants around the sofa to adsorb formaldehyde.

3. You can try a scavenger containing photophyll and spray it on the sofa, which is simple and fast. Photophyll is extracted from plants and can absorb and decompose formaldehyde.

4. The sofa cover and the like can be removed and cleaned with salt water.

Some. Wooden sofas are mainly the formaldehyde smell released by surface paint, leather sofas are mainly valued by fabric, and formaldehyde released by leather. Recommendations:

1. The taste of sofa wool can be removed by soaking it in salt water for 30 minutes, and then washing and drying it repeatedly.

2. For the problem of glue inside, you can open the sofa and ventilate it for a week, and use some plant liquid Dialin to decompose the formaldehyde in the glue.

3. Usually you can also put some activated carbon and leaf clay materials at home, sofas, cabinets for adsorption and decomposition, formaldehyde release is long-term, can be adsorbed for a long time, and will not be saturated.

4. If the surface is painted, move it out for ventilation, and then wipe it with salt water.
