China's hardware accessories industry, whether it is manufacturing or distribution industry, in the process of development from a big country to a strong country, the number of enterprises will be less and less, the scale and strength of enterprises will be greater and greater, will inevitably take a brand, rely on With its technological content, relying on its strong capital, it has implemented cross-regional, transnational, group-based, and chained operations.
Recently, the Beijing Consumers’ Association conducted a comparative trial of products for some of the sealed ceramic faucets currently on the market. Yesterday, the Beijing Consumers Association announced the results of comparative tests. The results showed that of the 50 ceramic sealing faucets tested, 34% failed to meet the standard. The test results once again questioned the quality of plumbing hardware.
According to tests, 50 samples had only two faucets with lead-free elements precipitated within 10 to 24 hours of water storage. Experts pointed out that faucets with poor quality materials are likely to exceed the “overnight water” lead content that is retained. If the volume exceeds a certain level, it will lead to lead poisoning.
The comparative test samples were all ceramic sheet sealed kitchen faucets, involving 50 samples produced by 50 companies in eight provinces and cities including Beijing, Shanghai, Guangdong, Fujian, Zhejiang, Jiangsu, Jiangxi and Hebei. By entrusting the National Building Materials Industry Construction Hardware Plumbing Product Quality Supervision, Inspection and Testing Center to test the faucet's logo packaging, salt spray test, flow, sealing performance, water efficiency, and lead concentration, there are 17 faucet samples in 50 samples. The project failed to meet the standard requirements, accounting for 34%.
It is reported that the reason why the overnight water that does not reach the standard faucet is prone to excessive lead is due to the fact that most ceramic chip faucets have been subjected to process restrictions and are mostly cast in copper alloys. However, the lead elements in copper alloys are exposed to air and the surfaces are very fast. Oxidation produces a protective film, but water can lead off the protective film of lead and lead to the precipitation of lead in the faucet.
