It is understood that China's current standard "Limits of Hazardous Substances in Wood Furniture for Interior Decoration Materials" only limits the four heavy metals such as cadmium, chromium, lead and mercury, and will be the first national standard for children's furniture in China on August 1. "General Technical Conditions for Children's Furniture", on this basis, new standards for the four heavy metals of antimony, selenium, arsenic and antimony have been added, which undoubtedly raise the quality threshold for children's furniture. When reporters visited the furniture and building materials market, they found that many manufacturers of children's furniture, adult furniture and office furniture could not produce heavy metal content test reports. Although consumers' awareness of environmental protection has improved, few people have asked about the heavy metal content of furniture when selecting furniture. In the investigation, the reporter found that the sales staff often boasted: "Our furniture uses environmentally friendly paint or water-based paint, does not contain heavy metals, and does not need to be tested." Other manufacturers claim that the furniture surface uses wooden stickers, so it will not Contains heavy metals. Wang Jing, a professor-level senior engineer at the China Building Materials Science Research Institute, said that manufacturers claim that furniture does not contain heavy metals and is suspected of misleading consumers. Objectively, water-based paints may also contain heavy metals. These heavy metals may come from the fillers used in the production of water-based paints - mineral powders, such as talc, titanium dioxide, etc. If these mineral powders have problems, then Bring heavy metals into the water-based paint. According to the relevant national standards, no matter which processing technology is used by the manufacturer, the furniture products should be tested for heavy metal content. It is understood that according to the "Limits of Hazardous Substances in Wood Furniture for Interior Decoration Materials", four heavy metals such as cadmium, chromium, lead and mercury 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 noticed that the parents' awareness of environmental protection has generally improved. Most parents ask for the amount of formaldehyde released from the furniture when they choose furniture for their children. However, few parents will ask whether the heavy metal content exceeds the standard. And most parents often choose colorful furniture in order to meet the needs of their children. According to Wang Jing, children's furniture usually has more colors and more vivid colors. It is worth noting that whether the furniture paint is oily or water-based, the brightly colored paints generally contain more heavy metals than ordinary paints. Some children's household items, such as colored fabrics and textiles, contain heavy metals. According to the reporter, the soluble heavy metals in wood furniture products mainly come from the paint coating film on the surface of the product, especially the color paint content. In addition, inorganic pigments are usually made from natural minerals and are produced through a series of chemical and physical reactions, which inevitably contain trace amounts of heavy metals. The "General Technical Conditions for Children's Furniture" has increased the limit requirements for four heavy metals such as antimony, selenium, arsenic and antimony. It is because children often use their mouths and hand rubs for everyday contact, which makes it easy to bring harmful substances. Into the body.
