The trend that precision cast stainless steel faucets completely replace copper faucets
Excessive lead content in faucets has caused widespread concern in the world. Recently, faucet production workers have revealed that all copper faucets on the market are all lead brass, and even yellow miscellaneous copper is used, which greatly increases the lead content of faucets. Most of the traditional copper faucets contain excessive lead, causing secondary pollution to drinking water. If absorbed into the human body, it will cause great harm, and the harm is comparable to 'poisoned milk powder.' The TV station conducted a 32-hour experiment on 13 faucet samples and found that the lead content of the faucet soaking water of 9 brands exceeded the national standard.
Where does the lead in the water come from? Why do you say that the lead in the faucet will pollute the drinking water?
There are two main sources of lead in drinking water. One is caused by the arbitrary discharge of industrial pollutants and wastewater, causing water pollution; the other is secondary pollution caused by the traditional copper faucet manufacturing process.
The content of lead in the human body continues to accumulate, exceeding 100mg/L can cause lead poisoning. The symptoms of lead poisoning vary according to the body's resistance, circulatory system and other factors. The most serious can lead to dizziness, mental decline, and even death, while the milder ones may be headaches, unresponsiveness, and hyperactivity. These symptoms are difficult to be taken seriously by people in normal life.
The harm of lead to the body!
When the blood lead content exceeds the standard, it usually causes: headache, dizziness, nausea, retching, palpitations, unresponsiveness, confusion, pallor, anemia, vasospasm, children’s mental decline, fatigue, hyperactivity, irritability , Have aggressive behavior, etc. If you do not pay attention to it, once lead poisoning, the harm to the human body is irreversible, especially the damage to the liver and kidney function is the most deadly.
The above symptoms occur when the lead exceeds the limit. Don't be careless, you should go to the hospital for examination in time to avoid catastrophe.
How to choose the decoration of copper faucet with excessive lead and great harm?
Dongguan Gaogang Precision Casting 304 Stainless Steel Faucet came out.
1. Stainless steel does not contain lead, is acid and alkali resistant, does not corrode, does not release harmful substances, and will not pollute your tap water source.
Copper contains lead. Copper will contain lead and grow patina to varying degrees, polluting your tap water. The 'lead-free copper' mentioned in the market means 'low lead content
2. The surface of the stainless steel faucet never rusts, beautiful and durable.
stainless steel faucet does not need electroplating, the surface is polished (polished) to show the true color of stainless steel, and it can always maintain the silver-white luster. The polished stainless steel faucet has been used for 20 years and 30 years, it is still clean and beautiful, luxurious as new. 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 copper products must be electroplated, and the best treatment method for the copper surface is to electroplate a layer of nickel or chromium. The electroplating layer will gradually peel off depending on its electroplating quality and thickness. One year for the faster ones, and 3-5 years for the slow ones, gradually lose their surface gloss and pitting, and finally the electroplating layer peels off and the copper rust is exposed.
3. Stainless steel faucet is easy to clean:
The best cleaning materials for stainless steel faucet are: any kind of washing water and steel ball. The more polished, the brighter and brighter as new. The copper faucet cannot be cleaned with washing water and hard towels, because the washing water will corrode the plating layer, and cleaning objects such as hard towels will scratch the plating layer.
There are two main processes for stainless steel faucets on the market: bar processing and precision casting (also called dewaxing casting).
Because of the low process difficulty in bar material processing, most manufacturers use bar material processing, which is cut and shaped by CNC machine tools and other equipment. The advantage is that the processing difficulty is low. The disadvantage is that cutting will cause the inside of the main body to be not smooth, and the long time of use is easy to hide dirt and dirt, which directly affects the water quality and harms health. Welding joints and missing welding lead to water leakage; the faucet style is single;
Due to the complicated production process and high production cost, only a small number of domestic manufacturers have 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 materials meet the American standard. The main body of the faucet is smooth and consistent inside and outside, no welding is required, no water leakage, not easy to hide dirt and dirt; the faucet has a variety of shapes and styles. The disadvantage is that the production process is complex, and only a small number of manufacturers have precision casting technology.
Precision casting, we are serious; healthy life, you deserve to have.
