The environmental protection of office furniture has always attracted much attention. The release of formaldehyde in office furniture has always been a headache. If the amount of formaldehyde released is too large, it will endanger human health. So what are the influencing factors of formaldehyde emission from office furniture? How to avoid the harm of excessive formaldehyde to human body.
Environmental protection standards for formaldehyde emissions from office furniture:
Chinese national standards implement mandatory environmental protection standards for formaldehyde emissions from office furniture: E1, ≤1.5mg / L (dryer method), ≤0.12mg / L (climate box method, used in arbitration). Products that meet national environmental protection standards are not harmful to humans under normal conditions of use.
Factors affecting the release of formaldehyde from office furniture:
1.Bearing rate
The so-called load factor refers to the ratio of the surface area of the office furniture exposed to the air to the indoor volume. The larger the load factor, the higher the formaldehyde concentration. Therefore, under the condition that the functions are basically satisfied, the number of office furniture in the indoor space should be reduced as much as possible, thereby reducing the formaldehyde emission in the office furniture.
2. Decoration method
The form of decoration of the surface of the office furniture has a clear blocking effect on formaldehyde. In the construction process, attention should be paid to the use of low-formaldehyde-releasing adhesives, various decorative materials and coatings, and reasonable processes to ensure that no new formaldehyde release is caused after decoration.
3. Use environment
The use environment has a great impact on formaldehyde emission from office furniture. Temperature, humidity, and ventilation can affect formaldehyde emissions. Under normal climatic conditions, if the temperature is increased by 8 ° C, the formaldehyde concentration in the air will be doubled; if the humidity is increased by 12%, the amount of formaldehyde released 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 aging time and conditions. The formaldehyde emission concentration of office furniture is directly 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.
