Mr. Liu recently called the newspaper to talk about buying a modular desk and found that the formaldehyde was seriously overdue. He specially bought a second-hand degree room for children in the middle school in Nanshan, followed by simple decoration to purchase new furniture. I finally chose the right combination desk, but when the desk was delivered to the home and assembled, Mr. Liu and his family found that the desk had a strong pungent smell, as long as they stood in the room for more than ten square meters. I was actually "smoked" and wept.
Mr. Liu had to let the child squeeze in the room of his grandparents for a while, and wanted to let the children move back to their room after the new table smelled. Unexpectedly, after nearly two months, the situation has not improved. Mr. Liu invited experts to test for his house. The result scared everyone to jump. The other problems of the house were up to standard. Only the combination desk in the children's room, the formaldehyde in the air exceeded the standard by 70 times. Mr. Liu immediately contacted the merchant to inform the truth, and returned the over-standard desk to choose another brand. “Whether it is building materials or furniture, how should consumers buy it? I hope that your newspaper can ask relevant experts to give us some advice.†Mr. Liu suggested.
In order to avoid indoor air pollution during the decoration process, we must first strictly control the pollution of building materials from the source. How to choose? What is the key to selecting materials? Recently, the reporter interviewed relevant experts.
★ Formaldehyde, benzene and radioactive materials are the three major culprits
Material selection in plates, paints and adhesives
Li Cuncai, secretary general of the Shenzhen Building Materials Industry Association, said that to avoid pollution, the core problem is to prevent formaldehyde, benzene and radioactive substances. Formaldehyde is mainly found in wood, radioactive materials are mainly found in stone, and benzene is mainly found in paints.
If the formaldehyde exceeds the standard, it will have obvious stimulating effect on the nose, trachea and eyes, and it can cause serious laryngeal cancer. If the radioactive substance exceeds the standard, its radiation is harmful to the human body; if the benzene exceeds the standard, it will cause fatigue, dizziness and serious coma. White blood cells are reduced. It can be seen that the key to material selection is in plates, paints and adhesives. Li Cuncai cited some methods for the classification and purchase of some building materials.
Artificial panels: various composite flooring, large core panels, veneers and MDF are the main sources of formaldehyde pollution. It is recommended that the formaldehyde can be used to eliminate harmful substances on the board before the decoration. When purchasing a composite wooden floor, it is very likely that the stimulating taste will exceed the standard when taking a piece in the newly opened box.
Glue paints: such as furniture paints, wall paints and various adhesives used in decoration, are the main source of benzene pollution. Consumers are advised to go to a specialty store set up by the manufacturer to purchase or select water-based materials that do not contain benzene.
Stone class: It is very important to choose the color. According to tests, different colors of stone have different radioactivity. The highest is red and green, while white and black are the lowest. Therefore, red, green or granite with large red spots should be carefully selected. Granite should not be used indoors, especially in bedrooms and children's rooms.
★When you choose furniture, ask, tell, and look carefully
Huang Weiye, president of the Shenzhen Furniture Industry Association, said that consumers should pay special attention when choosing furniture. In order to make the board more robust and durable, moisture-proofing agents and binders need to be added to the wood-based panels, which are the main sources of free formaldehyde.
According to reports, some sheet mills are cheap, and the urea aldehyde glue with simple process and high profit is selected. Urinary aldehyde glue is a kind of glue synthesized by chemical reaction between urea and formaldehyde. If it is used improperly, it will cause the formaldehyde content of the board to exceed the standard seriously. At present, some large brand manufacturers have implemented the "European E1 standard", which is based on the content of harmful substances such as formaldehyde in the board, and is a new standard adopted and implemented in China.
Huang Weiye suggested that when buying furniture, ask, tell and look carefully: ask the manufacturer's information and selection criteria; open the door, open the drawer, smell the furniture for irritating taste, because the standard furniture will not bring Have a pungent smell; look at the test report, instructions for use, understand whether the furniture is up to standard and whether there is any legal institution notarization.
★ Don't just pay attention to the price should choose the safe brand
Many consumers have focused on the price, and only choose the price after they choose the style. In fact, the price difference between good and bad quality brands is large. When selecting materials, you should choose the production and suppliers of the big brands.
Huang Weiye analyzed that the products of brand products or large-scale production enterprises are put on the market after strict process control and product testing, while the inferior raw materials are not processed and processed, which inevitably contains a lot of elements harmful to the human body.
In addition, when purchasing, consumers pay attention to whether there is a “Green Ten Ring†logo certification issued by the State Environmental Protection Administration of China. Also available are currently environmentally friendly materials, including water-based paints, PVC environmentally friendly wallpapers, and plant glues.
Li Cuncai suggested that the selection of building materials should go three steps: first, buy formal nationally certified building materials; second, pay attention to the use of paint; the third step, after the renovation, must be ventilated, conditionally looking for testing institutions for testing.
★ Experts call for strengthening supervision
Relevant experts believe that in terms of material selection, consumers are actually relatively weak. As a government or society, in fact, consumers should not be overwhelmed by this pressure.
Li Cuncai appealed that the market supervision department should first purify the problems existing in the market. In addition, it can entrust or decentralize relevant functions to the relevant social organizations to identify or check for consumers, and reject products that are not environmentally friendly or falsely environmentally friendly.
At the same time, it also called on relevant departments and merchants to strictly implement the relevant national environmental protection policies, laws and regulations and environmental protection standards, in accordance with the provisions of the Consumer Protection Law, adopt positive operations to protect the legitimate rights and interests of consumers, implement the compensation reserve system and consciously Accept social supervision.
