It is reported that in recent days, China's industry and commerce departments have detected 84 kinds of unqualified products in the inspection of 11 types of materials commonly used for interior decoration such as waterproof coatings and pipes, among which tap products account for nearly half, and 38 kinds of quality cannot meet standards. Almost all of these 38 products have many problems, ranging from less than the corrosion resistance requirements, while the weight of lead and chromium exceeds the national mandatory standards.

Zhang Jing, the person in charge of Jiangnan Hardware, told reporters that the current selection of materials used by faucets and water by manufacturing companies is mostly cast copper alloys, dezincification-proof copper, stainless steel, etc. These materials will contain varying degrees of serious harm to the human body. Lead, cadmium, chromium, arsenic elements. The harm to the human body is actually caused by these common toxic pollutants. Among them, excessive lead can damage the nerves, hematopoietic and reproductive systems, and it is particularly harmful to children. It can affect children's growth and intellectual development, and long-term contact with chromium compounds can cause contact dermatitis or eczema. In addition, heavy metals can strongly interact with proteins and enzymes in the human body, causing them to lose their activity, and may also accumulate in certain organs of the human body, causing chronic poisoning.
It is reported that the Ministry of Environmental Protection of the People's Republic of China has also issued a national environmental protection standard for water faucets (faucets) this year. This standard is highly concerned with human health. Heavy metals, as well as hazardous substances such as benzene and formaldehyde, have strict limits. In terms of protecting human health, the limits for the precipitation of heavy metals requiring taps to be in contact with water are: lead ≤ 5 μg/l, chromium ≤ 10 μg/l, cadmium ≤ 0.5 μg/l, and arsenic ≤ 1.0 μg/l.
â– Don't let prices cover your eyes
Diligence and thrift are the traditional virtues of the Chinese nation, and economic benefits are the pursuit of people's home decoration. However, when choosing these materials that are related to people's health, quality and safety are the key factors.
Zhang Jing of Jiangnan Hardware said that taking the faucet's spout as an example, iron is only a few dollars, and copper is worth several tens of dollars. Although these seemingly inexpensive accessories can save some money for decoration, once the quality problems occur, the harm caused to people's lives is very serious. Heavy metal poisoning causes the protein in the body to coagulate. If it is only slightly poisoned, it needs a lot of milk to drink. The protein in milk reacts with heavy metals, so that it will not injure people's bodily functions for the time being, but they need to go immediately after drinking. Hospital for medical treatment. “The new faucets look very sleek, and ordinary consumers generally have difficulty recognizing their pros and cons. In addition, in order to pursue low prices, some consumers choose some quality-leading faucets, which will bring water security to people. It is a great hidden danger. Therefore, when consumers choose a faucet, they must not only choose products based on their prices,†said Miss He, who heads a bathroom brand.
â– three steps to buy an optional tap
In addition to purchasing regular outlets and famous brands, some shopping tips are also worth learning. In general, your purchase can be divided into three steps.
Look: Jiangnan Hardware official said that the valve body of the regular brand faucets are all made of brass. After grinding and polishing, the surface is plated with nickel and chromium. The coating of the regular products has specific technical requirements, and through the neutral salt spray test, there is no rust phenomenon within the specified time limit. In addition, consumers can open the faucet and observe its internal structure and interface. If it is copper, it is yellow and there are obvious signs of polishing, while the zinc alloy will not have such a phenomenon.
Listen: “The easiest way to identify the quality of a faucet is to use its hand to weigh it.†Zhang Jing said that a good faucet is made of copper, and it is a brass that has been processed and refined, and the general faucet is mostly Is made of alloys, and even some of the leading still use engineering plastics molded from the most simple identification method is to gently tap by hand, plastic faucet can not emit metal sound.
Q: When purchasing a faucet, full understanding and detailed inquiry are also essential. There seem to be many problems with seemingly simple faucets. Having a certain understanding of it and then making a decision is the best policy.
