The new national standard promotes the development of the hardware industry

Since July last year, the “excess lead in faucets” has been like a blockbuster, exploding the sensitive nerves of the public, and aroused consumers' doubts about the production line of faucets. In order to fully understand the production status of major brands of copper and stainless steel faucets in China and even the world, the National Building Materials Testing Center of the Sanitary Ware Committee of the All-China Federation of Industry and Commerce specially invited the mainstream media matrix of China to launch a Chinese plumbing hardware industry enterprise in early September Field visits.

According to research and development experts from brand companies such as Luda, Jiumu, Zhongyu, Shenluda, Huihuang Plumbing, etc., copper and lead coexist, and there is no copper with a purity of 100% in nature. In the process of producing brass as a faucet, a small amount of lead needs to be added to improve the cutting performance of brass. If lead is not added to the faucet at all, not only will there be problems such as difficulty in cutting and poor forging performance, but the finished product will also crack due to poor stress corrosion resistance. Xie Xin, secretary general of the Sanitary Ware Committee of the All-China Federation of Industry and Commerce, said, “The current copper faucet is almost harmless to the human body under normal use. The lead element absorbed by the human body from different channels every day has a safe value. The faucet is in the water. During the flow, the precipitation of lead is almost undetectable, and the panic of lead poisoning from the tap is an unfounded fallacy.'

Hong Guangming, general manager of Shenluda Group, said that mainstream faucets in developed countries in Europe and the United States use brass as the main raw material. The main reason is the antibacterial property of copper, which is an advantage that other materials such as stainless steel and plastic do not have. Zhu Jianhong, deputy general manager of Luda Group, believes that China has the world's largest low-lead copper production and manufacturing base, and it is at the forefront of the world in the research and production and processing of low-lead copper. Lin Xiaofa, chairman of Jiumu Kitchen and Bathroom, said that the group's laboratory tests found that stainless steel faucets do not contain lead, but contain nickel, chromium, manganese and other elements. Excessive precipitation of these heavy metals can also cause serious harm to the human body. Cai Jilin, CEO of Zhongyu Sanitary Ware, said that completely lead-free copper faucets do not exist. The concept of lead-free in the market actually refers to low lead. It has high requirements for copper composition, process technology and electroplating treatment, and powerful companies are talented. Conditions for production.

The National Building Materials Industry Building Hardware Plumbing Products Quality Supervision, Inspection and Testing Center launched a new version of GB 18145 (instead of the 2003 version) 'ceramic sheet sealing faucet' in early 2014, which imposed mandatory requirements on the precipitation of 17 heavy metals, etc. Effectively adopt the North American NSF61 standard, which has strict control significance on the market. Cai Shizhan, executive deputy general manager of Brilliant Plumbing, said that all powerful companies in China's sanitary ware industry have participated in the discussion and formulation of this standard. Only 30-35% of large and medium-sized enterprises can adapt to the new standard. Some small and medium-sized enterprises without strength may face elimination. The new national standard will play a powerful role in promoting the industry.
