Knowledge Release: Five Factors Affecting Formaldehyde Emission From Furniture
Influence
furniture
The factors of formaldehyde emission are intricate.
Throw away the product as a whole.
base material
As for wood-based panels, there are many factors that affect formaldehyde emission from wood based panels, such as wood, plastic, plastic, hot pressing and post processing.
Formaldehyde emission
Impact.
Decoration method
The sealing effect of furniture surface decoration on formaldehyde is very obvious.
In the specific implementation process, attention should be paid to the selection of low formaldehyde release adhesives, various decorative materials and coatings as well as reasonable processes to ensure that new formaldehyde releases do not occur after decoration.
Loading rate
The so-called load rate refers to the ratio of surface area to indoor volume of indoor furniture exposed to air.
The greater the loading rate, the higher the formaldehyde concentration.
Therefore, in the case of basically satisfied functions, the number of furniture in the indoor space should be minimized so as to reduce the formaldehyde emission in furniture.
Diffusion route
It is worth emphasizing that the importance of edge seal of panel furniture.
In the design of furniture, the sheet can be used as much as possible when the strength and structure are satisfied.
Use environment
The use of the environment has a great impact on formaldehyde emission from furniture.
Temperature, humidity and ventilation affect formaldehyde emission.
Under normal climatic conditions, the temperature will increase by 8 degrees, and the formaldehyde concentration in the air will be doubled. When the humidity is increased by 12%, the formaldehyde emission will increase by about 15%.
Therefore, air conditioning and fresh air system can be used to regulate indoor temperature and humidity and fresh air volume, so that formaldehyde emission can be properly controlled.
Time and conditions of release
The formaldehyde emission concentration of furniture is directly proportional to the release time after production. It should be put out for a period of time before being used and placed in a high temperature and high humidity environment to speed up formaldehyde emission, so as to reduce the pollution in later use.
