Tannery is always inevitable irritating smell, but in Suichang County San Ren Shexuan Xuan Lok Carbon Composite Materials Co., Ltd., a roll just down the assembly line leather exudes a scent of bamboo charcoal. This is not ordinary leather, but a new product. Guan Ning Zhang, director of the company said that they give this new type of leather named "charcoal", because it is mainly used for the bamboo charcoal powder material, through a certain formula, the ratio of production of environmentally friendly leather. Bamboo charcoal on the harmful substances in the air adsorption. However, charcoal, leather seems irrelevant two things, but also how to get along? New cars, new furniture, etc., because of its decorative materials, leather itself contains formaldehyde, ammonia, benzene, toluene and other residues, not only bad news, but also harmful to humans. "Whether it can make carbon into leather and exert its function of absorbing harmful substances can not solve the problem that the leather industry has been hard to remove the harmful residues such as pentachlorophenol and hexavalent chromium." Guan Ning said: Had been holding this idea to do. In 2005, Guanning Zhang independently developed a "green carbon composite material and preparation method" won the national invention patent, then, after three years of thousands of tests, Xuanle Charcoal Composite Co., Ltd. has finally succeeded in producing New product - carbon skin. Good things are always bright spots. Xuan Le charcoal won the gold medal in participating China Jiangshan Forest Products Expo. In the exhibition of Asia's International Green Furniture Fair, was organized by the organizers in the middle of a significant booth. Global Sources magazine, the global trade platform for global trade of more than 560,000 buyers worldwide, has also placed it on the front cover for free. Because of this, in November last year, the global retail tycoon Carrefour, the United States "testrite" companies to enter the procurement in China, the first met met Xuanle Charcoal Composite Materials Co., Ltd., and gave him 45 minutes of products State time, then included in the carbon skin procurement directory. If you do not have a patent certificate, not witness, no one will believe that this product is from a small business with only a dozen employees hand. Guanning Zhang said that due to a lack of funds, the company can only present itself as a high-quality product to a small company. At the end of last year, tested by the National Building Materials Testing Center, the carbon skin has significant degradation effect on the formaldehyde in furniture and new car. No detection of hexavalent chromium, pentachlorophenol, etc. by the SGS SGS Technical Service Co., Ltd. Peculiar to leather residues of harmful substances. According to Zhang Wenbiao, Zhejiang Forestry University, Dr. introduction, this new environmentally friendly bamboo charcoal composite material, called the composite leather landmark revolution. Carbon leather and leather and other man-made compared to no benzene, toluene and other harmful substances, will not release harmful gases and compounds. Now, specifically for Honda, Toyota and other companies to provide interior leather manufacturers have come to order. At the same time, Guangdong, Hangzhou and other places a number of well-known domestic furniture, leather manufacturers want to cooperate with them.
