After the renovation of new homes, the issue we are most concerned about is environmental issues. The most important issue is formaldehyde. In the furniture there will be the presence of formaldehyde, then the formaldehyde content of furniture is how much it? Follow the small series together to take a look at the standard formaldehyde content of furniture !
Furniture formaldehyde content standard
1, the People's Republic of China national standard "solid wood composite floor" provides: A type solid wood composite floor formaldehyde emission is less than and equal to 9 mg / 100 grams; B solid wood composite floor formaldehyde emission is equal to 9 mg -40 mg / 100 grams.
2. The “Technical Requirements for National Environmental Labeling Products--Artificial Wood Panels†stipulates: The formaldehyde emission in artificial panels should be less than 0.20 mg/m3; the formaldehyde emission in wooden floors should be less than 0.12 mg/m3.
3. The national standard of the People’s Republic of China “Standard for the Sanitization of Formaldehyde in Indoor Air†stipulates that the maximum allowable concentration of formaldehyde in the air in the room is 0.08 mg/m3.
European E1 environmental protection standard is: formaldehyde content ≤ 9mg/100g. E0 level environmental protection standard is: formaldehyde content ≤ 3mg/100g. However, China's current E0 environmental protection standard is: formaldehyde content ≤ 5mg/100g. E1 grade is ≤15mg/100g.
In Europe, wood furniture is divided into three levels according to formaldehyde emission: E1 (formaldehyde content less than 10mg/100g), E2 (formaldehyde content less than 30mg/100g), and E3 (formaldehyde content less than 60mg/100g).
How to detect formaldehyde content
1. The reaction of mobilizing plants can also detect formaldehyde to a certain extent. For example, plants withered and died. This happened just after moving into a new house. The pets who are raised are sick, do not eat food, have low resistance, and have low vitality. They always like to stay quiet. If such a situation occurs, and your family has similarly low resistance, it can basically confirm that your new home is problematic.
2, for how to detect formaldehyde content, detection of formaldehyde is mostly using physical and chemical methods, this is the most sophisticated method, but also the method used by third-party testing companies, most people are incapable of using. Detection methods include: AHMT spectrophotometry, phenol reagent spectrophotometry, gas chromatography electrochemical, sensor method.
3, according to their own feelings to determine the quality of the furniture reminds you that the whole family moved into a new home after the collective cold, immunity is low, easy to headache dizzy. Reduced energy is easy to wear out. It has a pungent odor, especially if you feel tears in your eyes when you are near a piece of furniture. Explained that the formaldehyde in the furniture exceeded the standard. At this time, we should grasp how to measure the formaldehyde content, do more precise inspections, and keep the room well ventilated.
Green furniture selection criteria
The first is the plate, because the environmental performance of furniture is mainly reflected in the plate, and the formaldehyde content of the good plate is particularly low.
Plates are mainly divided into 3 kinds, E2 level is in line with domestic standards, formaldehyde content of 10-30 mg / 100 grams; E1 level is in line with European standards, formaldehyde content is less than or equal to 9 mg / 100 grams, E0 level is the most environmentally-friendly world's top standard The formaldehyde content is less than or equal to 3 mg/100 g. If there are conditions that must be selected above the E1 level, environmental performance is better.
Secondly, from the finish, the plate finishes used by good companies are more resistant to scratches and do not fade. Poor finishes are not wear-resistant and will fade gradually after 3-6 months, resulting in a yellowing effect.
