AQSIQ recently tested 85 wood furniture manufacturers across the country and found that enterprises with excessive formaldehyde accounted for 76.9%, the highest exceeding the standard by 116 times. Some people called this event "formaldehyde door."
Furniture, especially small-brand furniture, has become a serious disaster area for formaldehyde. Indoor formaldehyde pollution has become an important killer of health.
How to get out of the "formaldehyde door", how should ordinary consumers deal with formaldehyde exceeding the standard, avoid indoor formaldehyde pollution, live in a cleaner and healthier environment... With a series of questions, the reporter conducted a survey.
It has been two years since the renovation of the new house, but it has been unable to stay. The reporter accompanied Ms. Zhang, who lives in Tiexi District of Shenyang City, to her idle “new houseâ€. As soon as the door opened, a pungent smell rushed. "It’s been two years, and the taste is still so big. I really didn’t want to.†According to Ms. Zhang, two years ago, she spent 400,000 yuan to buy this 60 square meters near the Tiexi Department Store in Shenyang. The second-hand house of rice, the result of the renovation was only a few days, she and her family appeared symptoms of itching, cough and so on. Ms. Zhang rushed to find someone to test, and the results showed that the indoor formaldehyde exceeded the standard. So she rushed out of her new home and rented a room outside to stay.
In the interview, the reporter learned that, like Ms. Zhang, there are not a few people who are forced out of the house by "poisonous furniture." Children's furniture, desks, computer desks, bed furniture and security doors have become the three major focus of complaints about "poisonous furniture" in recent years.

Completely formaldehyde-free, but not over-standard can be controlled
Relevant experts from the Provincial Quality Supervision Bureau told reporters that indoor air pollution is most prominent with formaldehyde pollution and benzene pollution.
According to experts, the main source of formaldehyde pollution is artificial boards. Formaldehyde has strong adhesion, which can strengthen the hardness and anti-insect and anti-corrosion ability of the board. Currently, urea-formaldehyde resin with formaldehyde as the main component is used as a binder in various particleboard, medium-density fiberboard and plywood on the market. Inevitably, it will contain formaldehyde. In addition, the use of adhesives is required for the decoration of new furniture, walls and floors. Therefore, wherever there is a useful adhesive, formaldehyde gas is always released. If it exceeds the standard, it will cause harm to the human body.
The effects of formaldehyde on human health are mainly manifested in olfactory abnormalities, irritation, allergies, abnormal lung function, and abnormal immune function. When the formaldehyde content in the indoor air is 0.10 mg/m3, there is odor and discomfort; when the content is 0.50 mg/m3, it can irritate the eyes to cause tearing; when the content is 0.60 mg/m3, it causes throat discomfort or pain. High concentrations can cause nausea, vomiting, cough, chest tightness, wheezing and even emphysema. Long-term exposure to low concentrations of formaldehyde gas can cause headache, dizziness, fatigue, bilateral asymmetric sensory disturbances and excessive perspiration and visual impairment, and can inhibit sweat gland secretion, resulting in dry and chapped skin; when the concentration is high, the nasal mucosa, The upper respiratory tract, eyes and skin are highly irritating and poison the nervous system, immune system, liver and the like.
Therefore, experts say that for consumers who buy furniture, the most effective way to prevent indoor air pollution is to choose a healthier board.
However, can you completely eliminate formaldehyde by using healthy plates?
The reporter visited a furniture manufacturing company in Shenyang. The person in charge of the company told reporters that from sheet metal to furniture, it needs to be processed by veneering, painting and edge sealing, unless all zero aldehyde paint, zero aldehyde edge seal and zero aldehyde veneer are used, otherwise even Formaldehyde†sheets will also introduce formaldehyde due to these processes, and true “formaldehyde-free†processing is difficult.
"But we should distinguish the primary and secondary issues." The person in charge said that the long-term formaldehyde release of furniture comes from the wood-based substrate. The amount of formaldehyde introduced by veneers, paints, etc. is very small compared to it. At the same time, since these formaldehydes are distributed on the surface of the furniture, most of them can be volatilized within 2 weeks to 3 weeks, so there is no health hazard to the human body. Therefore, the "zero formaldehyde" furniture produced with zero formaldehyde sheet should be a concept of "about zero formaldehyde." That is to say, with the existing technology and conditions, zero formaldehyde production is difficult to achieve, but it can be controlled without exceeding the standard.
Excessive quality is not uniform
In the list of problem companies published by the state and the provincial quality supervision departments, the reporter found that it is mainly local small brand products. Why do small furniture brands become the hardest hit areas with excessive formaldehyde emissions?
The reporter interviewed a powerful furniture company in our province. The person in charge of the company told the reporter that in order to get the products out of the country, they introduced European environmentally friendly sheets with formaldehyde emission levels two to three times lower than the domestic standards. However, the reporter learned from the insiders that many small enterprises sacrificed product quality in order to obtain huge profits. The environmental protection grades of materials such as sheet adhesives were not up to standard, or the production process was not strict, resulting in repeated violations of formaldehyde.
In this regard, some experts suggest that in view of the current situation of many building materials and furniture products in the decoration and decoration market, the relevant departments should create a green building materials product purchase consulting platform and establish a quality database of green decoration materials in the home decoration market. Testing and consulting services for the categories of building materials and furniture.
In addition, today's consumers, health and environmental awareness have been significantly improved, and the quality of products is increasingly demanding. The use of healthy plates to provide consumers with more healthy and environmentally friendly custom furniture is an obligation of a responsible custom furniture company and a reflection of corporate social responsibility. Companies must be responsible for the quality of their products and must be responsible for the health and rapid development of the entire industry.
In this regard, the industry pointed out that in the processing of furniture, once the formaldehyde content of the sheet, glue, paint can not be guaranteed, the formaldehyde content of the furniture is likely to exceed the standard. Therefore, it is particularly important for furniture companies to strictly control the quality of the coatings used in the processing.
At present, the popularity of environmentally-friendly furniture paints such as water-based wood lacquers is relatively limited, the coating requirements are relatively high, and the prices are relatively expensive. In the case of soaring raw material prices, some furniture manufacturers choose to use less inferior paint products for painting. In fact, companies with strength and commitment to the development of environmentally friendly furniture can fully interface with coatings companies and promote the popularization of environmentally friendly coating products such as waterborne wood lacquers, light curing and powder coatings.
Furniture companies should also strictly control quality in the production process. Some furniture factories believe that the paint used for furniture painting has nothing to do with itself, does not carry out inspection, and is not strictly controlled in the production process. This is a misunderstanding and an important reason for the excessive formaldehyde content in furniture. Only by improving the production level and strictly controlling the raw materials and various processing links can the furniture enterprises ensure the environmental protection of the furniture produced.
At present, the country has not completely unified the equipment and methods for formaldehyde detection. The furniture industry still needs to control the quality of the coating paint through the industry self-discipline, and solve the problem of excessive formaldehyde in the source, so that consumers can buy peace of mind and use it with confidence.
There is no description in the industry management non-standard specification
The reporter went to the Jiulu Furniture Market in Tiexi District, Shenyang City. When he walked into a furniture store, he smelled a pungent smell. The store sales staff said: "We are selling wooden furniture here, all of which are environmentally friendly products." When the reporter asked why the furniture here had a pungent smell, the salesperson first claimed that it was the original taste of wood. Later, it was straightforward to say that these formaldehydes are mainly used for wood preservation, and formaldehyde is very volatile. As long as it is dried for a while, it will not be harmful to the human body.
In the repeated insistence of the reporter, the salesperson brought the furniture manual to the reporter. However, when the reporter saw the instructions provided by the merchant, he found that there was no data on the toxic content of the home.
In the case of excessive toxic substances in furniture products, in fact, the country has long been an industry norm, but for various reasons, these industry norms have had little effect. According to the reporter's understanding, as early as 2004, the General Administration of Quality Supervision, Inspection and Quarantine promulgated the mandatory standards for the "Furniture Instructions for Use". According to the requirements of the General Administration of Quality Supervision, Inspection and Quarantine, when selling furniture, merchants must provide consumers with detailed instructions for use, and clearly indicate in the instruction manual the environmental indicators, raw material data, and toxic substances of furniture products. Content and so on.
If this industry norm can be achieved, then the home is poisonous and non-toxic, and the instructions can be clearly understood.
Master the necessary identification common sense to ensure decoration and environmental protection
Of course, consumers can't pin their hopes on the self-discipline of the business. Song Guangsheng, director of the China Indoor Environmental Monitoring Center, reminds people that when buying furniture, consumers need to have the necessary common sense. The most important thing is that consumers should bear in mind that “five don’t buyâ€: don’t buy if there is a strong pungent smell; don’t buy furniture made of wood-based panels without all the edges; the price is relatively low, and the price is particularly easy. Buy; do not buy the inherent quality of the problem; not regular manufacturers, no factory inspection or quality inspection certificate, do not buy. In addition, consumers should also let furniture dealers produce instructions marked with formaldehyde content.
The National Environmental Product Quality Supervision and Inspection Center reminds consumers that indoor air quality is related to the safety and health of the family. After the renovation of the home, you must ask the authoritative testing agency to conduct indoor air quality testing before check-in, and then check in after the air quality is up to standard.
It is necessary to select decorative materials with qualified performance and “contaminant limitâ€. Choose the decorative materials products produced by the certified companies, and give priority to the decorative materials of well-known brands that can be trusted.
To choose a formal decoration and decoration company, and sign a formal decoration and decoration contract to ensure the quality of the decoration.
In addition, indoor ventilation and ventilation, and the cultivation of some green flowers are also effective ways to eliminate indoor air pollution. Green flowers such as spider plants, aloe vera, gerbera, etc. can play a role in purifying the air.
When purchasing floor mats, we should first make clear our own needs. Generally speaking, for indoor floor mats, the main material can be acrylic, cotton and microfiber. If you choose a floor mat for the bathroom, the main reason is that it absorbs water. Therefore, cotton or microfiber floor mats should be selected, especially microfiber materials. People step on it directly after taking a bath, which not only absorbs water quickly, but also feels very comfortable.
Our floor mat product back adhesive selection of natural latex coating, non-toxic, odorless, no deformation, no sticky, no mildew.
