In order to improve the living environment, we will buy a variety of furniture to decorate the beautiful home. However, new furniture generally contains formaldehyde (ie, odor in the air) that makes people uncomfortable. The factors affecting the amount of formaldehyde released from furniture are complex, such as: rubber, rubber, hot pressing, post-treatment. Furniture is the main source of formaldehyde for indoor use, and it is necessary to emphasize the following six factors:

First, the plate variety

The sheet of furniture is the primary factor determining whether the furniture is environmentally friendly. Now the home on the market has two kinds of solid wood furniture and panel furniture. As the name suggests, solid wood furniture means that all materials are natural wood materials that have not been reprocessed, and no artificial board is used. Made of furniture, this type of furniture is very environmentally friendly. The plate type has MDF, EGGER board, etc. The plate has a large amount of gum, so the amount of environmentally friendly glue required for post processing is small, and the amount of formaldehyde released is small.

Second, the decoration method

The sealing effect of the furniture surface on the formaldehyde is very obvious. In the specific implementation process, attention should be paid to the use of low formaldehyde release adhesives, various decorative materials and coatings, and reasonable processes to ensure that no new formaldehyde is released after decoration.

Third, the space carrying rate

The so-called load ratio refers to the ratio of the surface area of indoor furniture exposed to air to the volume of the room. The higher the load factor, the higher the formaldehyde concentration. For example, in a 20-square-meter bedroom, more furniture is placed, and the amount of formaldehyde released is large. Therefore, in the case where the function is basically satisfied, the number of pieces of furniture in the indoor space should be minimized, thereby reducing the formaldehyde emission in the furniture.

Fourth, the diffusion route

Mainly for the importance of edge sealing of panel furniture. When designing furniture, thin plates can be used as much as possible while meeting the strength and structure.

Fifth, the use of the environment

The use environment has a great influence on the formaldehyde emission of furniture. Temperature, humidity, and ventilation all affect formaldehyde emissions. Under normal climatic conditions, the temperature will increase by 8 ° C, the concentration of formaldehyde in the air will double; the humidity will increase by 12%, and the amount of formaldehyde will increase by about 15%.

Therefore, under the premise of conditions, air conditioning and fresh air system devices can be used to adjust the indoor temperature and humidity and fresh air volume, so that formaldehyde emission is moderately controlled.

Sixth, Chen time and conditions

The formaldehyde emission concentration of the furniture is proportional to the post-production release time. It should be placed for a period of time before use, and placed in a high temperature and high humidity environment during the discharge, to accelerate the emission of formaldehyde to reduce the pollution in the future use. Therefore, the owner's decoration has just started, basically you can go to buy furniture, so that you can volatilize the formaldehyde in the furniture as soon as possible.

The main source of indoor formaldehyde:

Wood-based panels for interior decoration. Formaldehyde-based urea-formaldehyde resin is the main raw material for the production of interior decoration plywood, blockboard, medium density fiberboard and particleboard. The formaldehyde contained in the plate will be slowly released into the surrounding air. The longest release period can be more than ten years, which is the main body for forming free formaldehyde in indoor air.

Synthetic fabrics such as carpets. Adhesives in carpets and interior materials such as wall coverings, wallpapers, and foams also emit formaldehyde. In order to improve the properties of synthetic fibers, resin finishing is usually carried out using a formaldehyde-containing finishing agent. These resin-finished chemical fabrics release free formaldehyde during use and storage. Therefore, the formaldehyde released by the synthetic fabric can not neglect the pollution caused by the living environment.
