Lead in the faucet exceeds the standard to reveal the consumer's cheats

Some time ago, there were news and reports about the lead in the faucet exceeding the standard, so that many consumers "smelt the lead color change." I have to sigh that in the rapid development of science and technology, our quality of life is improving, and the health risks around us are also increasing. Today, Xiaobian will bring everyone to understand the lead problem of the faucet and how to choose a quality faucet, hoping to help you in your healthy life.

1. Why is there lead in the faucet?

According to statistics, most of the faucets currently on the market are made of iron, copper, stainless steel, alloys, plastics, etc. as the main material. Due to the superiority of copper materials in many aspects, especially with the emergence of copper-free lead (low lead), more than 90% of high-end faucets at home and abroad have been cast with copper. In order to save costs and improve production efficiency, some companies add a certain amount of lead in the production and processing of copper alloys. Lead elements can form a protective film when contacted with air, and lead molecules in the protective film may precipitate under long-term scouring. At the same time, because tap water uses chlorine as a disinfectant, residual chlorine in the water accelerates aging and lead precipitation. Generally, the use of copper faucets and water pipes for more than 5 years will increase the amount of lead released.

Second, how big is the harm of lead?

Lead is a heavy metal element that harms the nervous system, blood, bones, digestion, reproduction and other systems of the human body. It has been designated as one of the carcinogens by the International Cancer Organization. Lead poisoning damage is most severely damaged by the nervous system, which can lead to slow response, decreased intelligence, and decreased memory. Lead is especially harmful to children, and children's absorption rate of lead is 8 times. Lead poisoning seriously affects children's intelligence and physical development.

Third, how do consumers buy high-quality faucets?

We use water every day. The health of the water affects the health of the family, and the faucet is closely linked to the water. For safety and health, we should purchase a reliable, water-saving and durable faucet during home renovation.

1. Look for the brand to be guaranteed

Consumers should go to the formal market when buying faucets and buy well-known brands so that they can choose products that are safe. The use of faucets is about family health and must not be cheap. There should be brand identification, quality assurance and after-sales service instructions in the regular faucet packaging box. Remind everyone to buy is to be cautious, in order to ensure that the lead content does not exceed the standard, try to choose stainless steel faucet.

2, observe the surface coating

In order to prevent the faucet from being oxidized, the faucet will be coated with a layer of nickel or chrome on its surface. The nickel or chrome has the function of resisting neutral hydrochloric acid, protecting the faucet from corrosion for a long time. When purchasing, look at the place with sufficient light. There are no oxidized spots on the surface of the faucet, no pores, no leakage plating and bubbles, and burn marks. The color is uniform and there is no burr and sand.

3, pay attention to internal structure and material

The instructions should be read at the time of purchase to understand the internal structure of the faucet. Ceramic faucet faucets are recommended. These core valves are made of high-resistance ceramics. Even with 60 psi of water pressure, they are free to switch and prevent leakage. For gaskets, the recommended 矽 washers can withstand hot and cold water pressure without leakage.

4, inspection faucet switch structure

Finally, check the design rationality of the product. First move a few switches to see if the parts are tight and tight. When twisting the switch, the hand feels soft as well. If the hand feels uncomfortable or fluffy, it means that the assembly structure is unreasonable. Such a faucet may have insufficient water supply when it is used, or water leakage may occur when the water pressure is increased.

Small faucets, seemingly inconspicuous, can cause losses to consumers in the event of quality problems. The use of lead exceeding the standard faucet can cause heavy metal poisoning and endanger the health of the family. Today, with the rapid development of science and technology, we must be more vigilant about the hidden "health killers" while improving the quality of life.

Here are all Vacuum cleaner power tools and the designated carbon brushes,motor brushes, electric brushes, motor brushes, electric motor brushes or simply brushes.

For each power tool, there are usually two carbon brushes to choose from: With automatic stop and without automatic stop. Carbon brushes with automatic stop have a spring through the length of the carbon brush. When the carbon brush wears out, the spring gets released, the current to the carbon brush gets interrupted and your power tools switches off at once. The advantage: No additional wear and tear to your power tool. Carbon brushes without automatic stop do not stop functioning at once, but performance of your power tool will detoriate rapidly. Although handy as a warning sign, this usually isn't very beneficial to your power tool.
