Benzene is a strong carcinogen. Formaldehyde, benzene, ammonia, and radioactive materials are four pollutants in interior decoration. Formaldehyde is a potential carcinogen. Formaldehyde is an indispensable material for adhesives used in sheet metal processing. Because the chemical reaction of formaldehyde is not thorough in inferior adhesives, free formaldehyde will be emitted in a large amount, which will cause harm to the human body. Therefore, it is very necessary to master how to distinguish the basic knowledge of environmental protection plates.
1 See if the product has passed the certification of China's environmental labeling products The China Environmental Labeling Product Certification Committee is a certification body composed of 11 bureaus, including the State Bureau of Quality and Technical Supervision and the State Environmental Protection Administration, which embodies third-party certification under the leadership of the government. The certificate issued represents the government's recognition and recommendation. The Chinese ring logo certification is a dual-compliance certification for a company's registered trademark product series in terms of quality and environmental protection, rather than just a batch of product environmental certification. China Ring Mark Certification is the most authoritative and most trustworthy environmental protection certification in China, and it is also the highest international standard certification in the world. Its graphic is a series of ten plus sun, mountain and water graphic combinations. The certified company usually sticks the logo in front of each board. At present, only a few domestic wood processing companies have passed this certification.
2 See if the company has passed ISO14000 series environmental management system certification. The ISO14000 series environmental management system certification is a certification of the environmental impact of the company's processing, including the discharge of waste water and waste steam, as well as the worker's operating environment, waste pollution to the environment, and many other aspects. It is also produced by the company. The product is certified in terms of environmental stability.
3 Look at the product's environmental protection level. Starting from July 1, 2002, the state imposed restrictions on the release of formaldehyde from sheet metal. For products that failed to pass the Chinese environmental labeling certification, if the amount of formaldehyde released can meet the basic requirements of E1 and E2, the product can be listed. Sales, but E2 level is limited to outdoor use. In this regard, consumers have to keep their eyes open. Because E2 has a lower interest rate than E1, consumers should not be confused by the appearance of price when purchasing plates, and mistake E2 plates for environmental protection. For interior decoration.
4 Two misconceptions about whether products are environmentally friendly. 1 . Emphasis on odor: Plates are mostly sold in a transparent environment with large air circulation and are difficult to identify by smell. In addition, the release of formaldehyde is a slow process, and even if it does not smell at that time, it does not mean that there will be no taste during the later period of use. 2 . Excessively believe in the test speech: The test lecture is valid only for the batch inspection sample and does not indicate that all products are qualified. Since inspection speeches are mostly sent for examinations instead of spot checks, it is easier for manufacturers to obtain a qualified test lecture.
