Substandard taps or lead poisoning
Recently, the Beijing Consumers Association conducted a product comparison test on some ceramic sheet sealed faucets currently on the market. The results showed that among the 50 ceramic sealing faucets tested, 34% did not meet the standard. The test results once again questioned the quality of plumbing hardware products.
According to the test, when 50 samples were filled with water for 10-24 hours, only two taps were lead-free. Experts point out that taps with substandard materials are very likely to cause excessive amounts of lead in the “overnight water” contained therein. If they exceed a certain level in human size, lead poisoning will occur.
The samples for this comparison test are all ceramic sheet sealed kitchen taps, involving 50 samples produced by 50 companies in 8 provinces and cities including Beijing, Shanghai, Guangdong, Fujian, Zhejiang, Jiangsu, Jiangxi, and Hebei. Entrusted by the National Building Materials Industry Building Hardware Plumbing Product Quality Supervision, Inspection and Testing Center to test the faucet’s logo packaging, salt spray test, flow rate, sealing performance, water efficiency, and lead precipitation concentration, among the 50 samples, there are 17 faucet sample parts The project failed to meet the standard requirements, accounting for 34%.
It is reported that the main reason why the overnight water of substandard faucets is prone to exceed the lead is that most of the ceramic chip faucets are cast with copper alloys due to process limitations, and the lead element in the copper alloy will quickly surface when it comes in contact with air. Oxidation produces a protective film, but water can make the lead protective film fall off, causing the precipitation of lead in the tap.
my country’s plumbing and bathroom hardware industry has grown out of nothing and has continued to flourish for decades. At present, China has become the world’s largest producer and consumer of plumbing and bathroom hardware facilities, and well-known domestic plumbing and hardware brands have also appeared in the international market. As market competition intensifies, the property market is sluggish, and market demand is declining, plumbing and bathroom hardware companies also need to improve themselves, change their development direction, focus on improving product quality, improve product functions, and continue to tap and meet the various needs of target consumers to create Brand awareness and reputation.
With the improvement of consumers’ requirements for quality of life and the deeper emphasis on health, plumbing hardware products should also be improved in time to meet consumer needs as much as possible.
In view of the various types of faucets on the market with different functions, some people in the industry suggest that consumers should pay more attention to the material and check the valve core when purchasing. The valve core is the key to the faucet. Products with better quality use ceramic valve cores. , It has the characteristics of strong wear resistance and good sealing performance; low-grade products mostly use copper, rubber and other seals, which have a short service life but low price. At the same time, consumers should also carefully check the electroplating quality of the faucet when buying. A good electroplating is as bright as a mirror, and the trace disappears quickly when you press it on the surface with your hand; you should also test the feel of the tap switch and choose the one that feels easy and rotates smoothly; You can also check the quality of the faucet by hand. Good faucets are generally heavy.
