On the morning of December 28, Xu Xu, chairman of the Minmetals Import and Export Chamber of Commerce, said at the International Rare Earths Symposium in 2010 that China had imported 10,381 tons of rare earth minerals from January to October this year, which exceeded 10,000 tons for the first time, an increase of 144% year-on-year.
He said that environmental issues have become a bottleneck in the development of rare earths in China. China's reduction of rare earth production is due to environmental issues. According to the data he provided at the seminar, the nation's rare earth industry emits 13 billion cubic meters of exhaust gas and 25 million tons of waste water. "It can be seen that the long-term use of rare earth has caused serious damage to me."
He suggested that China's rare earth smelting and separation technology is relatively advanced, and Chinese companies are willing to cooperate with other countries in the world to jointly develop rare earth resources outside China.
What materials can I choose for the cabinet handle? Which is good?
At present, plastic, zinc alloy, aluminum alloy, copper, stainless steel, gold and silver are commonly used in the market (these two kinds are basically useless unless the family really has no money to spend)
Plastic handle should be the cheapest. It's rare to know much about it, and it's not recommended to buy it. After all, it takes several years to install a handle, or it's more reliable to buy a metal handle. People of insight are welcome to add it in the comment area.
Zinc alloy is the most common material in handles. More than 80% of the handles you see in the market are made of this material. Why do you ask? Most of the handle manufacturers produce zinc alloy handles. The price of raw materials is medium, not as expensive as copper, which is easier to process. After electroplating, it is very beautiful and has enough weight, So consumers are willing to buy this high-quality and cheap product.
Aluminum alloy handle is popular in recent years. It is cheaper than zinc alloy and has low material density.It include aluminum handles,aluminium door handle,handle aluminium,edging handle aluminium,aluminum profile handle.
Copper handle is the best material, which can be said to be the standard configuration of high-end handle. American, European, light luxury and other cabinets can be selected. It has a large density and heavy weight. It feels very textured, and its appearance and color are also very beautiful. In ancient times, the noble with status was equipped with a copper handle as standard. Of course, the price is also expensive. The raw materials are more than twice that of zinc alloy and aluminum alloy, so the finished products will only sell more expensive!
The style of stainless steel handle is relatively simple. Due to processing and market demand, there are few styles of stainless steel handle, and there is basically only one color, that is, wire drawing texture. We rarely buy it at home, and basically export it abroad.
The handle is bought according to the place of origin. The handle in Shanghai, Shenzhen and Foshan is better than that in Wenzhou. The electroplating process in Guangdong is really good. The price of the handle in these places is more than twice that in Wenzhou!
