The media exposed the truth of the furniture industry: "Zero Formaldehyde" is just a legend

Wood contains trace amounts of formaldehyde adhesive, etc. It is also easy to have formaldehyde.

Recently, the news that an actress caused death from cancer caused by excessive formaldehyde in the furniture has been seen in various media. The topic of excessive formaldehyde in furniture has once again attracted attention. The reporter visited the weekend and found that furniture manufacturers have declared that the furniture is “zero formaldehyde” in order to meet the needs of the public. However, because the wood itself contains trace amounts of formaldehyde, and the wood will use adhesives and other materials in the processing, the furniture must be truly Zero formaldehyde is basically just a legend.

Visit: "Zero Formaldehyde" into a slogan

Newly purchased furniture may release formaldehyde, which has become a "consensus" for many citizens. However, the reporter recently visited and found that the furniture and building materials with the concept of “zero formaldehyde” have become the mainstream of the industry. Many manufacturers have vowed to ensure that the current furniture has been updated and will not release formaldehyde.

"Now our furniture is 'zero formaldehyde', that is to say, the furniture is bought indoors and will not release any formaldehyde. It is absolutely completely environmentally friendly." Ms. Liu, who moved to a new home and is ready to become pregnant, told reporters that She recently saw a number of building materials markets, almost all manufacturers said that "furniture zero formaldehyde", and even some sales staff have come up with a test report in line with EU standards. However, Ms. Liu decided to rent an old house to live in, and wait until the home was renovated and ventilated for half a year.

In the furniture city near the racecourse in Tianhe District, a furniture store owner selling wooden flooring and other plates told reporters that “this matte wooden floor is absolutely free of formaldehyde.” He said, “This wooden floor is in the process of production. The palm oil wax with pure natural ingredients is specially used as an adhesive. The natural formula naturally contains no formaldehyde. The price of this 12mm thick wooden floor is almost the highest in the store, reaching 88 yuan / square meter.

The reporter noticed that in the process of introducing the furniture “zero formaldehyde”, the sales staff often used the words “E0 grade environmentally friendly zero formaldehyde”. In the introduction, the above words often mean that the product has reached a high standard and environmental protection level.

Truth: "Zero Formaldehyde" is just a legend

The reporter interviewed a number of timber industry bosses to understand that the term "furniture zero formaldehyde" is not entirely correct. “Naturally grown wood itself contains trace amounts of formaldehyde. Urea-formaldehyde resins and phenolic resins are used in the production of various wood-based panels and various plastics, coatings, adhesives and synthetic fibers. These resins are also released. The source of formaldehyde."

Therefore, the “zero formaldehyde” emphasized by the manufacturer can only guarantee that there is no artificial or formaldehyde-releasing substance in the production process, but it does not indicate that the furniture wood itself is “zero formaldehyde”.

Then, what is the meaning of the E1 and E0 environmental standards used in the promotion of manufacturers? According to the reporter's information, at present, the formaldehyde limit level is divided into three levels of E2, E1 and E0, namely E2≤5.0mg/L, E1≤1.5mg/L and E0≤0.5mg/L. The data shows that the formaldehyde content of drinking water is 0.9 mg / L, that is, the formaldehyde content of the E0 standard is less than that of drinking water. The Japanese "F4 Star" standard (≤0.3mg/L) is the most stringent environmental standard recognized by the international community. The E1 environmental standard is a national mandatory health standard, and it is a mandatory “safety standard line”.

Formaldehyde release should be ≤1.5mg/L

In China's national standards, the quality standard for formaldehyde content is GB18584-2001 "interior decoration materials, limited quantities of harmful substances in wood furniture". The reporter found that the standard stipulates that the amount of formaldehyde released should be ≤1.5mg/L.

In terms of children's furniture, national standards are more stringent. On August 1, 2012, China's first national standard for children's furniture, "General Technical Conditions for Children's Furniture" (GB 28007-2011) was officially implemented. The standard Chapter 5 safety requirements, Chapter 6 warning signs are mandatory, and the remaining chapters and terms are recommended. Among them, harmful substances such as formaldehyde, heavy metals, and decomposable aromatic amines which may be released from materials such as wooden parts, product surface coatings, textile fabrics, leather, and plastics are limited.

In addition to formaldehyde, it must be multi-pronged

The reporter was informed that the most accessible formaldehyde in the daily life of the citizens comes from furniture, electrical appliances, decorative materials and textiles. So how to reduce or eliminate formaldehyde?

First of all, in the decoration of the house should use high-quality paint or even water-based paint to reduce the release of formaldehyde from the source. When choosing all kinds of furniture, electrical appliances, decorative materials and textiles, you need to choose a brand that you can trust.

Secondly, it is very necessary to maintain ventilation after the renovation of the house. The measured data shows that in the case of normal decoration, the release period of indoor formaldehyde will last for 3 to 15 years. Therefore, it is very necessary to remove formaldehyde in combination with other methods.

Finally, the use of photocatalyst, activated carbon, Maya blue and other materials for formaldehyde removal.
