The Casting of Stainless Steel Taps Replaces Copper Heads

The excessive lead in taps has caused widespread concern in the world. Recently, leading production workers exposed the copper faucets on the market are all lead brass, and even more yellow copper, which greatly increased the lead content of the faucet. Most traditional copper faucets contain lead exceeding the standard, causing secondary pollution to drinking water, and causing great harm when absorbed into the human body. The hazard is comparable to “poisoned milk powder”. The television station conducted 32 hours of experimentation on 13 leading samples and found that the lead content of the leading soaking water in 9 brands exceeds the national standard.

Where does the lead in the water come from? Why does lead in the tap contaminate drinking water?

There are two main sources of lead in drinking water. One is the random discharge of industrial pollutants and wastewater, resulting in water pollution; the second is secondary pollution caused by the traditional copper faucet manufacturing process.

The content of lead in the human body continues to accumulate, and over 100 mg/L can cause lead poisoning. Lead poisoning is based on various factors such as the body's resistance and circulatory system. Symptoms appear to be different. The most serious ones can cause dizziness, mental decline, and even death. The lighter ones may only be headache, unresponsiveness, and hyperactivity disorder. These symptoms are difficult to be taken seriously in normal life.

Lead harm to the body!

Excessive levels of blood lead often lead to headaches, dizziness, nausea, retching, heart palpitations, dullness, confusion, paleness, anemia, vasospasm, mental decline in children, sleepiness, hyperactivity, grumpy, and attacks. Sexual behavior and so on. If you do not pay attention, once the lead poisoning, the harm to the human body is irreversible, especially the damage of liver and kidney function is the most deadly.

Excessive lead in the above symptoms, do not careless, should be promptly to check, so as not to cause a disaster.

Copper faucet lead exceeding the risk of large decoration how to choose?

Guangdong Arnold poetry cast 304 stainless steel faucet.

1. Stainless steel does not contain lead, and is acid and alkali resistant, free of corrosion, does not release harmful substances, and does not pollute your tap water source.

Copper contains lead, copper will lead to varying degrees and growth of copper rust, polluting your tap water source. The "lead-free copper" in the market means "low lead content", not "unleaded."

2. Stainless steel faucet surface never rust, beautiful and durable.

The stainless steel faucet does not require electroplating, and the surface is polished (polished) to highlight the true color of stainless steel, which can always maintain its silver-white luster. The polished stainless steel faucet is still clean and luxurious and luxurious as it is for 20 years and 30 years. The hardness and toughness of stainless steel are more than 2 times higher than that of copper. Never rust, never corrode, never deform. The surface of the copper product must be plated. The best treatment for the copper surface is to plate a layer of nickel or chromium. Electroplating depends on the quality of the electroplating, the thickness, will gradually peel off. The fast one year and the slower ones gradually lose their surface luster and their spots during the next 3-5 years. Finally, the plating layer peels off and exposes the copper rust.

3. Stainless steel faucet is easy to clean:

The best cleaning products for stainless steel faucets are: any kind of detergent water and steel balls. The more you shine, the brighter you are. Copper faucets cannot be washed with detergent and hard towels, as the cleaning water will corrode the plating and hard towels and other cleaners will scratch the plating.

Stainless steel faucets on the market are mainly two kinds of processes: bar processing and precision casting (also called dewaxing casting).

Bar processing due to the difficulty of the process, most manufacturers are using bar processing, CNC machine tools and other equipment, cutting molding. The advantage is low processing difficulty. The disadvantage is that the cutting will cause the inside of the main body to be not smooth, and it will be easy to use for a long time to collect filth. The welding seam will cause the leakage due to the false welding and leakage welding. The style of the faucet is simple in shape; the high scrap rate of raw materials leads to high production cost. Some black-heart manufacturers even use raw materials containing hexavalent chromium, which is a highly toxic and carcinogenic substance. The human body absorbs hexavalent chromium and is prone to poisoning and even cancer.

Due to the complicated production process and high production costs, precision casting has only a small number of manufacturers in China with precision casting technology. The advantage of precision casting is that it can change the nickel and chromium content of the faucet and make the raw material reach the American standard. The inside and outside of the main body of the faucet is smooth and consistent, no welding is needed, no leakage is caused, and it is not easy to collect filth; the shape of the faucet is various in style. The disadvantage is that the production process is complicated, and only a few manufacturers have precision casting technology.
