Relatively speaking, solid wood furniture can only have a lower formaldehyde content. General furniture contains formaldehyde, especially in various man-made panels, the content of formaldehyde is higher. Relatively speaking, the formaldehyde content of solid wood furniture is less. In addition, the adhesives, coatings and paints used in wooden furniture also contain a small amount of formaldehyde.
According to the concept of solid wood furniture issued by the furniture industry: the solid wood furniture currently on the market can be roughly divided into three categories: all solid wood furniture, solid wood furniture and solid wood surface furniture.
All solid wood furniture is furniture made of the same kind of log sawn timber.
Solid wood furniture refers to furniture made of a mixture of solid wood and wood-based panels, that is, particleboard or MDF fiberboard with veneer veneer for the top, bottom, shelf and other parts of the side panels.
Solid wood furniture refers to furniture made of log sawn timber on exposed parts such as furniture doors and surfaces.
That is to say, as long as the main structure of the furniture uses solid wood structure, even if the door panels and side panels do not use solid wood, they can also be called solid wood furniture. Such solid wood furniture must have a certain degree of formaldehyde pollution due to the use of various wood-based panels and composite panels.
Here are several formaldehyde pollution of solid wood furniture:
No.1 Wood-based panels contain formaldehyde
For solid wood furniture made of a mixture of solid wood and wood-based panels, since the top, bottom, shelf and other parts of the side panels are made of particleboard or MDF fiberboard with veneer veneer, it may cause formaldehyde pollution. At the same time, solid wood furniture is made of log sawn timber on exposed parts such as furniture doors and surfaces, and other parts are also made of wood-based panels, which may also cause formaldehyde pollution.
No.2 Solid wood finger joint board contains formaldehyde
Most solid wood furniture generally use solid wood finger-joint boards as auxiliary boards for furniture, also known as single-layer solid wood finger-joint boards. This kind of board is sawed into small pieces of various solid wood materials, after deep drying, the small pieces are opened, and then the urea-formaldehyde resin adhesive is applied on the toothed parts and the sides of the small pieces, and then extruded and fixed. Wood resources can be effectively used. This type of finger-joint board uses relatively less adhesive, and is a wood-based board material with better environmental protection performance. At present, solid wood finger-joint boards are mostly used in some solid wood furniture, as lining boards, panels and partitions of solid wood furniture, and are also the main source of formaldehyde pollution in solid wood furniture.
No.3 Glue etc. contain formaldehyde
All solid wood furniture In the furniture production process, wood, panels, glue, paint, leather, etc. all contain formaldehyde. No matter how good the wood is, as long as glue and paint are used, formaldehyde will be released. Therefore, according to the production process of modern furniture, absolute “zero pollution” furniture is simply impossible.
No.4 Fake solid wood contains formaldehyde
It is sold as solid wood furniture as wood-based panel furniture. Some unscrupulous merchants in the market take advantage of consumers’ concern about the environmental protection performance of furniture, and put on the hat of “solid wood” for many wood-based panel furniture to sell, the most common of which are the so-called “solid wood density board” and “solid wood particle”. plate”. The so-called solid wood density board is a wood-based panel made of sawdust or broken wood boiled with a large amount of formaldehyde and glued together, while the solid wood particle board is what is usually called a particle board, which is made by adding adhesives to the particle board. In fact, this kind of products are very different from real solid wood furniture products, and there is a great hidden danger of formaldehyde pollution.
And here are some methods for removing formaldehyde from solid wood furniture:
1. Ventilation method. After the furniture enters the room, it is necessary to properly ventilate the room to reduce the content of formaldehyde.
2. Newly bought furniture can be soaked in vinegar with a rag and wiped with vinegar, which can reduce the formaldehyde residue on the surface of the furniture.
3. You can put more green plants in the furniture to purify the air, or some activated carbon, which can also reduce the formaldehyde content very well.
4. Of course, there are also many products such as activated carbon that absorb formaldehyde on the market, which can effectively reduce the formaldehyde content.
5. Photocatalyst decomposition method. Under the stimulation of light, the catalyst in the photocatalyst generates negative ions and hydroxyl radicals with oxygen and moisture in the air, which can oxidize and decompose various organic and inorganic pollutants.
