According to the Dahe newspaper: "The national standard for children's furniture has imposed stricter restrictions on heavy metal content, but this restriction seems to be empty." Ms. Wang reflects that she has turned to a number of furniture stores and found no heavy metals. Content test report for children's furniture. The interview found that in addition to children's furniture, China's national standard "Restriction of Hazardous Substances in Wood Furniture for Interior Decoration Materials" also imposes restrictions on four heavy metals such as cadmium, chromium, lead and mercury, but there are not many furniture products with heavy metal test reports. see. Reflexion: Children's furniture heavy metal report is difficult. Recently, Ms. Wang said with deep feelings that she did not expect the national standard to be implemented for two or three months. It is very difficult to find a heavy metal test report. The explanation of the merchant is even more confusing for her. . Ms. Wang said that her son is six years old every year. When he moved into a new house in May this year, his son had a separate room. Listening to the acquaintances of the decoration company, the environmental protection situation of the children's furniture market at that time was chaotic, and new national standards will be introduced from August, and this situation will be improved. So she and her husband decided to postpone the purchase of furniture for their son. “We have carefully studied the national standards for children's furniture and found that our understanding of the environmental protection of furniture is very limited.†Ms. Wang said that before she thought that the furniture for children was mainly to pick styles, colors, materials and formaldehyde. Through the study of the national standards for children's furniture, they found that the safety performance requirements of children's furniture are really important, such as the sharp corners, protruding parts, holes, gap size, stability and other aspects of children's furniture, etc. The protection is really not small. More importantly, the national standard has changed her understanding of environmental protection. Originally, when it comes to furniture environmental protection, the formaldehyde content is low. Through the national standards for children's furniture, she learned that the furniture contains soluble heavy metals such as antimony, arsenic, antimony and selenium. The 10 kinds of toxic and harmful substances inside may affect people's health, and the standards impose strict limits on their content. Ms. Wang said that she and her husband locked the time for their sons to buy furniture at eleven. First, they believed that the national standard for children’s furniture for eleven months was implemented for two months, and that the children’s furniture conformed to the national standard was more. Second, the price was cheaper at this time. . However, during the eleventh period, when they came to the store, they found that the shape of the furniture mostly met the requirements of the national standards, but when asked about the environmental issues that are more concerned about the heavy metal content, most of the merchants took out various "green". Certificates and quality inspection reports, claiming that their products are absolutely in line with national standards, are environmentally friendly products. They consulted the relevant certificates and quality inspection reports, and there is no relevant data such as heavy metals. In response, some merchants said that the quality inspection report did not list heavy metal projects, and the products were qualified products, indicating that the heavy metal content is in line with national standards or even no heavy metals, and it is not necessary to list them. Investigation: The heavy metal test report into a blind spot survey found that not only children's furniture, but also ordinary furniture, there is no heavy metal test report required by relevant standards. According to the "Limits of Hazardous Substances in Wood Furniture for Interior Decoration Materials", four heavy metals such as cadmium, chromium, lead and mercury in wood furniture must be within the limits of the standard, that is, lead ≤ 90 mg / kg, cadmium ≤ 75 mg / kg, Chromium ≤ 60 mg / kg, mercury ≤ 60 mg / kg. On the basis of the "General Technical Conditions for Children's Furniture", the limit requirements of four heavy metals are added, namely: 锑 ≤ 60 mg / kg, arsenic ≤ 25 mg / kg, 钡 ≤ 1000 mg / kg, selenium ≤ 500 mg / kg. The reporter asked some furniture marketing personnel about the heavy metal test report as a customer. Most of the marketers were very surprised, as if they had encountered an alien. Among them, a marketing staff of a solid wood furniture brand is very straightforward to say that people choose furniture to see whether the style, color, and material are environmentally friendly. Customers who ask for heavy metal test reports are the first to see it, even the relevant departments have not done it. This kind of inspection. Although most furniture manufacturers can't get test reports, most of the marketers still say that they are plausible and exciting. “Where is the heavy metal of wooden furniture? It is mainly the traditional lacquering process, and our lacquer is a new lacquer, so there is no heavy metal problem and there is no need to detect it.†At a store in Zhengyi Road, a brand of solid wood furniture staff said that The brand furniture surface adopts the world's most advanced plant painting process. Unlike traditional paints, it is necessary to add thinner materials, which fundamentally eliminates harmful chemical materials such as heavy metals, and there is no need to detect them. Because of this, "you can see our quality inspection report. The quality inspection department did not include heavy metals in the testing project. This also proves that our products do not have heavy metal problems and are worthy of safe use." "Now, there is a saying that the brighter the furniture, the greater the heavy metal content. This is widely spread, but it is actually wrong, misleading many people." A furniture store in a furniture store in Lushan Road In a nutshell, this statement is true for painted furniture, and it is wrong for furniture that uses inorganic pigments. Their brand of furniture is the use of natural inorganic pigments, a total of 13 colors, although the color is more, but the resin is pressed to the surface of the furniture sheet at 800 ° C high temperature, no paint, but will never contain lead, mercury Equal heavy metals. During the interview, some citizens were attracted by the new processes and materials promoted by the manufacturers, and they believed that the products using these processes and materials were reliable. For the heavy metal content in furniture, except for a few young fathers and mothers who know that children have heavy metal limits, most people do not know that wood furniture also has heavy metal limits. Many people believe that as long as the quality inspection report is qualified, the product can be used with confidence. As for the environmental protection problem, there is no smell and there is no formaldehyde, so you can use it with confidence. “The heavy metals in the furniture are mainly derived from the pigment coating on the surface of the product.†Lin Xuan, an observer, said that no matter the traditional paints mentioned by the merchants, or the resin or inorganic pigments, heavy metals cannot be excluded. Among them, the statement that inorganic pigments do not contain heavy metals is the most concealed, because inorganic pigments are usually refined from natural minerals, and natural minerals themselves do not contain heavy metals. They undergo a series of chemical and physical reactions to make inorganic pigments. The process requires heavy metals such as iron and lead as catalysts. To this end, the relevant national standards have made relevant regulations on the limit of heavy metal for wood furniture and children's furniture. Even for products that meet the requirements of national standards, the content of heavy metals is high or low, and relevant test reports should be available. Appeal: Heavy metal testing of furniture is not required to standardize the interview. It is found that when it comes to the environmental performance of furniture, people think of formaldehyde most. Little people mention heavy metals, and there are few known dangers to heavy metals. "As a harmful substance in furniture, heavy metal pollution is the same as formaldehyde, and the harm to the human body cannot be ignored." Ding He, an indoor environmental testing engineer, said that because volatile gases such as formaldehyde are irritating, people can easily feel it, plus In recent years, the promotion of formaldehyde hazards, people have generally paid attention to formaldehyde. On the contrary, the heavy metal content has no obvious stimulation to the human senses, and there is not much publicity about the relevant aspects. People don't know much. As a heavy metal in furniture, it mainly exists in the surface coating. Under the action of human body contact friction or suitable solvent, heavy metals may be brought into the body, that is, heavy metals can migrate into the human body through appropriate media. “Soluble heavy metals are extremely harmful to the human body.†Observer Zhang Qiusheng said that at present, the heavy metals that can be transported in furniture mainly include lead, cadmium, chromium, mercury, antimony, arsenic, selenium, tellurium, etc., which enter the human body beyond a certain amount. It can cause greater damage to human health. Therefore, relevant national standards impose restrictions on heavy metals in wood furniture and children's furniture. In terms of hazards, lead can damage human nerves, hematopoiesis and reproductive system, especially to children and adolescents, which may affect children's growth and development and intellectual development; long-term inhalation of cadmium may impair kidney and lung function; long-term exposure to chromium compounds may cause Dermatitis, eczema; chronic mercury poisoning mainly causes central nervous system diseases; sputum and arsenic have radioactive damage to the skin, which will cause skin pigmentation, leading to abnormal keratinization; when selenium is excessive, people will get rickets; sputum and skin or eyes It can cause a burning sensation when contacted. "Currently, many wood furniture and children's furniture do not have heavy metal test reports, but there are still some ways to distinguish whether their heavy metal content is up to standard." A furniture store executive who asked not to be named said that there is no heavy metal detection. There are many reasons for the report, but as a regular store, there is still a corresponding basis for purchasing furniture, and people can judge it accordingly. For example, their stores require that wood furniture products must implement GB18584-2001 "Limited Hazardous Substances in Wood Furniture for Interior Decoration Materials" and children's furniture must implement GB28007-2011 "General Technical Conditions for Children's Furniture". If the public is concerned about heavy metals, you can check Two points: As long as the implementation standards, as long as the products meet the above two standards, the qualified products indicated in the quality inspection report, the heavy metal content should meet the limit requirements; the second is the heavy metal content test report, the lower the heavy metal content, the safer the human body. The industry believes that at present, wood furniture, children's furniture lacks a heavy metal content test report, indicating that manufacturers pay insufficient attention to the national standard, and the relevant aspects are not well regulated. Executing qualified furniture products with national standards of heavy metal limit, if there is no heavy metal test report, then its "qualified quality" is questionable; without heavy metal test report, it can not achieve clear consumption. The industry has called for relevant parties to increase the publicity of relevant standards, increase supervision and inspection of relevant product compliance standards, regularly publish products that do not provide heavy metal content data, and expose false brands and products. Testing and publicizing heavy metal content data has become a must for all furniture manufacturers, creating an environment that understands consumption and healthy consumption, and effectively protects the legitimate rights and interests of consumers.
