Copper use in household appliances in a wide range

, especially in recent years, various studies have shown that copper has a good antibacterial effect of bacteria, which makes copper as a health materials would be more widely used in various home appliance products. Most consumers of copper and home appliances, in particular, little is known about the relationship with health. Therefore, this reporter interviewed the International Copper Association (China) Electric Project Team Leader Wang G.

Reporter: In the home appliance industry, the copper to the people is probably the deepest impression on the price of copper soared last year, led home appliances prices. It even does not care about prices of raw materials from many consumers are aware of the relationship between copper and home appliances.

Wang G: Copper is an important raw material of some appliances, it directly affects the prices of home appliances prices. At present, China-made color TV, DVD player, mobile phones, monitors, program-controlled switches, air conditioners, refrigerators, power tools, microwave ovens and other products of export volume and value of all rank first in the world, it has been the use of copper soared. In 2004, China's household electrical appliance, electronic and mechanical manufacturing industry of copper content, the proportion of the total domestic copper consumption to 34% or more. U.S. copper demand fell for 3 consecutive years.

Cause a substantial increase in China's copper was due to the rapid development of China's economy increased demand for copper, the other hand, the global copper and significant changes in consumption patterns. Chinese demand for copper, in addition to some increase in their actual consumption, the fact there is a significant component of "alternative consumption." In the form of export products, "transfer" to another country to consume.

World copper center now begin the transfer to China. For example, the world's largest copper products listed companies, the largest copper rod manufacturer and one of the largest manufacturers of magnet wire?? The United States, Phelps Dodge Corp., owned enterprise in Suzhou to produce high-quality enameled wire, the first a production reached 8160 tons. Some compressor manufacturers have also set up factories in China.

Reporter: Now we know some parts of some appliances are brass, in metal prices rising today, the support of your Association, and many companies are developing original electrical components do not use copper products use of copper. This is not the cost increase would result in it?

Wang G: This is not a question of whether a cost is an issue related to people's health. British scientists at the University of Southampton on the brass pots and pans and cooking utensils made of stainless steel The inhibitory effects of E. coli was found: E. coli can survive in the stainless steel cooking surface, 34 days, but can only survive in the surface of copper cookware 4 hours; Chile The scientists found that copper cookware can inhibit the growth of Salmonella and Campylobacter. In addition to kitchen appliances, the use of copper pipes can inhibit a variety of noxious bacteria, viruses and water, the growth of microorganisms; in the pool, copper is used to prevent algae contamination and transmission through the floor of tinea pedis; use of copper surface or Brass surface door knob and handles, and help reduce the spread of pathogenic bacteria; in hospitals and clinics, with a copper-based anti-bacterial paint with vigor, copper fittings installed in the door, to prevent the spread of disease.

Reporter: copper, it has long been widely used, such as the Bronze Age of China there. At that time, many vessels are copper's. Like wine and tableware are also washbasin copper. So that our ancestors made the use of copper utensils are very scientific.

Wang G: Of course, in the copper environment, a number of pathogenic organisms in drinking water, especially in E. coli inhibited by more than 99% of bacteria in water in 5 hours away. The existing water dispenser and washing machine appliances secondary pollution, are beginning to focus attention. Liner drinking fountains, waterways are not clean if long-term, it will deposit dirt into the breeding ground for bacteria; washing machine in the long-term use, the sleeve there is often laminated in scale, detergent free materials, clothing fibers and clothing into the Human organic matter, a lot of dust and other dirt, the dirt at room temperature in the breeding, fermentation, with the laundry when the internal water cycle of contamination of clothing, secondary pollution, harm to human health.
