As a small piece in plumbing parts, faucets have always been a small and insignificant role in people's attention and purchase. However, I did not expect the healthy killer hidden around me to be the little tap that I touch every day. Experts pointed out that the faucet with substandard material is very likely to cause the excess lead in the overnight water to exceed the standard, and even lead to lead poisoning. For a time, the faucet has fallen into a "lead crisis."
Inferior faucet harms not to lose melamine
The pass rate of taps sold in the market is low, not a case. As early as September 2010, the results of the national supervision of the faucet product quality showed that the qualified rate of ceramic sheet sealing faucets was 60%, of which 83 batches were exposed due to unqualified; in December 2011, Shanghai Consumer Protection Committee In the faucet comparison test, it was found that 22% of the sampled samples had lead exceeding the standard, and some products exceeded the standard by 20 times. At that time, the Shanghai Consumer Protection Committee had issued an advisory to the relevant enterprises, and recommended to stop selling the same batch, the same model products, and make corrections. Although most enterprises have actively rectified within the prescribed time limit and submitted written reports, there are still a few companies that refused to be rectified and handed over to the administrative department for handling, which laid the groundwork for today's leading lead.
Lead exceeds the standard, fierce danger does not lose melamine
It is reported that unqualified faucets are detected to exceed lead, especially in the faucet, the lead content in the overnight water is higher, and long-term use can lead to lead poisoning. Children and pregnant women are extremely sensitive to the toxic effects of lead due to the physiological characteristics of growth and development. Pregnant women with severe lead poisoning will have premature birth and miscarriage, and will affect the growth and mental development of infants and young children. In severe cases, dementia will occur.
"The long-term use of inferior faucets is unfavorable to the human body, and the use time is long, the gel will corrode and wear, and the faucet may have leakage problems." In a forum recently organized by a home network with the theme of faucet safety, Chaoyang bathroom vice General Manager Deng Shuyu said, “The lead content of faucets has standards. Excessive levels of heavy metals may lead to stones and even lead poisoning, especially to pregnant women and children. If consumers pay attention to this, they will find that they are inferior. The faucet harm is no less than melamine."
For the harm of inferior faucets, Professor Liang of the School of Resources and Environment of South China University of Technology pointed out that poor quality faucets may lead to secondary pollution of water quality. The faucet is closely related to daily life, and the quality and safety problems such as lead exceeding the standard frequently appear, which undoubtedly bury a great hidden danger to the health of the human body.
Material process limitations lead to lead exceeding
Experts pointed out that the reason why the overnight water that does not meet the standard faucet is easy to lead exceeds the standard is that most ceramic chip faucets are limited by the process and are cast by copper alloy with lower cost. When the lead element in the copper alloy is in contact with air, the surface It will oxidize quickly and form a protective film, but water can cause the protective film of lead to fall off, causing the precipitation of lead in the faucet. In addition, the content of lead in copper and copper faucet castings is usually 4% to 8%. If the faucet is not used for a long time, green rust will be generated on the inner wall, and harmful substances such as lead existing inside may be released into the tap water.
The China Quality Certification Center has launched a faucet safety certification, and the company or manufacturer that has obtained the logo will be clearly and reliably marked on the product and its packaging. Relatively speaking, some enterprises with poor reputation or poor strength cannot and do not want to mark reliable labels on their products and packaging, and the terminal storefronts cannot provide relevant test certificates. Due to the low attention paid by consumers to the faucet, it is basically not to look at the logo or certificate in this respect, which is another reason for the proliferation of inferior products.
It is understood that the major sanitary ware manufacturers in the world have strict control over the requirements for the infiltration of water in direct contact with drinking water. For example, the lead precipitation concentration specified in JC/T 1043-2007 "Sodium leaching limit" is not higher than 0.011mg/ L and national standard GB/T 17219-1998 "Safety evaluation of drinking water distribution equipment and protective materials", the lead value of invasive water is not higher than 0.005mg / L and so on. At present, some enterprises in the market use copper, zinc alloy water-passing parts and rubber-filled products in violation of regulations. The lead content exceeds the standard, and the quality of the faucet products is improved. The emphasis is on reducing the precipitation of heavy metals, especially lead-containing substances.
How to buy faucets
In view of the chaos of the faucet market, how to purchase qualified and safe faucets has become a major problem for consumers. Many manufacturers are striving to develop low-lead faucets. Because the country's management system for lead in faucets is still not perfect, consumers do not know how to distinguish.
In this regard, Hansgrohe national sales manager Tang Ming pointed out that "the current method to reduce the lead content of the faucet is to wash lead, but there is no way to completely eliminate it. The faucet itself will accumulate a certain amount of water. After a long time, it will absorb heavy metals. In general, Before using the faucet the next day, it is generally necessary to let the water accumulated in the faucet overnight and then use it."
According to the data, the quality of the products are all made of ceramic valve core, which has the characteristics of strong wear resistance and good sealing performance. Low-grade products use copper, rubber and other seals, and have a short service life, but the price is low. Therefore, when looking at the material, you should also check the valve core, which is the key to the faucet. Consumers can't see the spool when they buy, but they can easily judge whether the spool is good or bad according to the feel when turning the handle. Generally, the handle is turned up, down, left and right. If it feels light and has no blockage, it means the spool is better.
Another expert in the industry suggests that consumers should also carefully check the quality of the faucet when purchasing. The good plating is as bright as the mirror. Press the surface on the surface with your hand. The trace will disappear quickly. You can also test the feel of the faucet switch. Smoothly. In addition, you can also rub the weight of the faucet by hand. A good faucet is generally very heavy. However, some insiders have revealed that some manufacturers can make the faucet heavier by increasing the wall thickness of the faucet or adding other metal materials. Therefore, consumers should ask the salesperson for the test report, brand logo and after-sales service card. If the test report confirms that the product is qualified, you can use it with confidence.
