Environmentally-friendly wooden floors have become the general trend of home improvement, and the propaganda words of floor merchants are full of mystery. Various propaganda slogans of "green floor" and "zero formaldehyde floor" flooded the market, but for ordinary consumers, they did not have the ability and skills to choose a major. How to ensure that they can choose a truly environmentally safe wooden floor when decorating? According to experts from the National Indoor Environmental Pollution Control Guidance Center, the state has many hard indicators for "green" wood floors, such as formaldehyde content. At the same time, there are special green product certification institutions, and only products certified by authoritative professional institutions can be called "green environmental protection". We suggest that consumers can evaluate the choice of healthy and environmentally friendly flooring from the following points: 1, national professional certification standards: At present, China's current domestic environmental protection standards certification, including the certification of products adopting international advanced standards and the certification of environmental signs in China, belongs to the national environmental protection authority certification, among which the certification of products adopting international advanced standards is the most stringent certification for flooring manufacturers to pass the environmental protection series. At present, only a few flooring brands, such as Sao Paulo and Sheng Xiang, have obtained the product certificates issued by the National Standards Committee and adopted the international advanced standards, and simultaneously launched the health products reaching F ★★★ ★ (F4 Star) in Japan. Consumers should pay special attention to the signs recognized by these countries when buying. At present, some social organizations are also issuing various environmental protection standard certifications, but due to their lack of authority, inconsistent release standards and insufficient supervision of products, it is difficult to become a yardstick for measuring environmental protection products. 2. Technical management system and product quality: "amateurs watch the excitement, while experts watch the doorway". At present, the international quality management certification system recognized by the flooring industry is mainly ISO series. Taking Sao Paulo flooring as an example, its manufacturer, Hunan Kangpai Wood, has successively passed ISO900 1 International Quality System Certification and ISO 1400 1 International Environmental System Certification. He is currently the director of the floor professional Committee of China Forest Products Industry Association. In 20 10, Sao Paulo also obtained the first patent of flooring in China that reached the highest international environmental protection standard (named "Method for manufacturing environmental protection laminate flooring by vacuum ammonia treatment", China national patent number: ZL 2009 1 0303696.4). Before buying floor products, it can effectively ensure consumers to buy truly environmentally friendly floor products. 3, look at the brand: various brands emerge in an endless stream in the floor market, and industry experts suggest choosing the floor brand from the aspects of brand history and after-sales commitment. Take the typical Sao Paulo and icon in the industry as examples. Their brand history is more than 15 years, and the dealers are basically national. The after-sales quality commitment of their products can reach 15 years, which undoubtedly provides consumers with effective quality assurance and perfect after-sales service. 4. Look at the product range and related parameters: major brands have different product ranges, and not all products are of the highest environmental protection level. Take Sao Paulo floor and icon floor as examples. 20 1 1, F4 Star products with the highest level of environmental protection are promoted as the most powerful products, leading the domestic mainstream of floor environmental protection and low carbon. In addition to formaldehyde in the floor itself will pollute the indoor environment, industry experts also remind consumers that installation problems cannot be ignored when choosing the floor. If the installation is not standardized, it will also have an impact on environmental protection. In addition, if the adhesive in the floor is not up to standard, it will also cause indoor formaldehyde pollution. Therefore, consumers should also pay attention to the choice of floor brand dealers with good reputation and long brand time when choosing wood floors with good environmental protection performance, so as to ensure the comfort and health of the home environment from all aspects.
