Analysis of the five major factors affecting the formaldehyde emission of furniture

Decoration method

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

Load factor

The so-called load factor refers to the ratio of the surface area of ​​indoor furniture exposed to air to the indoor volume. The greater the loading rate, the higher the formaldehyde concentration. Therefore, when the functions are basically satisfied, the number of pieces of furniture in the indoor space should be reduced as much as possible, thereby reducing the emission of formaldehyde in the furniture.

Diffusion pathway

It is worth emphasizing the importance of edge banding of panel furniture. When designing furniture, thin plates can be used as much as possible while satisfying the strength and structure.

Use environment

The use environment has a great influence on the formaldehyde emission from furniture. Temperature, humidity and ventilation all affect the emission of formaldehyde. Under normal climatic conditions, when the temperature increases by 8 ° C, the concentration of formaldehyde in the air will double; the humidity will increase by 12%, and the amount of formaldehyde released will increase by about 15%. Therefore, under the premise of conditions, air conditioners and fresh air system devices can be used to adjust the indoor temperature and humidity and the amount of fresh air, so that the formaldehyde emission can be properly controlled.

Chen Fang time and conditions

The formaldehyde emission concentration of furniture is proportional to the aging time after production. It should be aging for a period of time before use, and placed in a high temperature and high humidity environment during aging to accelerate the emission of formaldehyde to reduce pollution in future use.
