The sofa and coffee table I bought last month, I always feel pungent when I get home, I m afraid it

There may be formaldehyde, because these furniture contain glue.

This shows that the boards used for sofas and coffee tables are not qualified.

Formaldehyde will be hidden in the new house, and the harm of formaldehyde is known to everyone, so we must be cautious in decoration and entering the house, so as not to cause pollution of home decoration and harm to the health of ourselves and family members. The active silicon of the goddess of the bamboo sea on the cats can be achieved immediately, so that the formaldehyde content of the house can be significantly reduced. It is placed in various places at will to prevent formaldehyde release sources and air-activated silicon is mainly composed of three parts: graphite microcrystallite, single planar network carbon and amorphous carbon.

Among them, graphite crystallites are the main part that makes up the active silicon. The crystallite structure of activated silicon is different from the crystallite structure of graphite, and the spacing between the layers of the crystallite structure is very large. Even when heated above 2100, it is difficult to convert into graphite, and this kind of microcrystalline is called non-graphite crystallite.

The vast majority of carbon is non-graphite. The crystallite arrangement of the graphite-type structure is more regular, and it can be converted into graphite after treatment. The non-graphitic microcrystallite structure gives the active silicon a well-developed pore structure, and its pore structure can be characterized by pore size distribution.

THE PORE SIZES OF REACTIVE SILICON RANGE FROM LESS THAN 2 NM TO SEVERAL THOUSAND NM. Some scholars have proposed to divide the pore size of active silicon into three categories: pore size less than 5 nm is microporous, pore size is medium pore at 5 60 nm, and pore size greater than 60 nm is macropore.

If it is the smell of the sofa material itself, it is a pungent smell and formaldehyde. It is recommended that windows be opened for ventilation. At the same time, measure the formaldehyde concentration, find a professional aldehyde removal unit to solve, after our new house is renovated, find Maya Blue to assist in the treatment, you can try it.

If the human nose can be asked, it is very serious, and it is recommended that you put it first.

Sofas are usually composed of three parts: frame, padding, and fabric upholstery.

Why does sofa contain formaldehyde? Formaldehyde is a chemical substance with a wide range of industrial uses, and it is one of the raw materials for many chemical products. The production of adhesives, coatings, and dyes is inseparable from 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. So how to control formaldehyde in sofas?

If it is a newly renovated house, it is recommended to carry out the overall management of the new house. Because the accumulation of multiple pollution sources will lead to an increase in the overall formaldehyde concentration in the house, and the formaldehyde will exceed the standard. Even treating a single source of contamination will not solve the problem.
