For many consumers who choose, it may be the first time to hear that the broken bridge aluminum profile has the concept of primary aluminum and secondary recycled aluminum. Recently, some merchants on the Internet said secondary recycled aluminum does not have a good article on primary aluminum. Just now, the editor also received a question from a consumer. Next, we will describe in detail the difference between the original aluminum or secondary recycled aluminum.
First of all, what I want to say is that our country is resources are big, but per capita, it seems that resources are scarce. Aluminum profiles can be recycled and processed. Consumers should not blindly pursue primary aluminum materials, if all aluminum products on the market are primary aluminum instead of recycled aluminum, how much waste of resources will China be, don't go wrong in the theory, the primary aluminum and secondary recycled aluminum of broken bridge aluminum profiles have no difference in characteristics. The state also encourages enterprises to use recycled aluminum instead of blindly exploiting aluminum resources for processing aluminum products.
The so-called primary aluminum is relative to recycled aluminum.
Primary aluminum is an aluminum ore obtained by mining aluminum ore. Bauxite, pure aluminum extracted from electrolytic cell.
Recycled aluminum is the aluminum produced by remelting discarded aluminum materials, such as abandoned automobile parts, cans, aluminum alloy doors and windows, etc.
So is there a big difference between the broken bridge aluminum profiles of primary aluminum and the broken bridge aluminum profiles of recycled aluminum?
The quality of the Broken Bridge aluminum profile is not determined by whether it is primary aluminum or recycled aluminum. There are two main factors depending on the quality of the Broken Bridge aluminum profile. One is the wall thickness of the Broken Bridge aluminum profile, and the other is the heat insulation strip of the Broken Bridge aluminum profile, even if the broken bridge aluminum profile is made of primary aluminum, and its wall thickness is thin, it is not solid. No matter how good the broken bridge aluminum profile is, the poor PVC insulation strip is used, which greatly reduces the service life.
Mineral resources it is often considered as non-recyclable and unsustainable resources. For example, oil, coal, etc. are indeed limited in reserves. If they are developed a little less, they will disappear once they are used after development. Mineral resources.
If we look at the circulation rate, we should encourage the extensive use of aluminum products and aluminum alloy, because aluminum is almost a completely recyclable raw material. Limit the use of some aluminum recycling rates that may be reduced, such as cans. Aluminum pot, an aluminum pot don't limit it, because it is difficult to be replaced.
Metallic aluminium chemical properties it is relatively active and easy to react with acid and alkali. Once it is directly corroded or oxidized by strong acid, it is strong Alkali corrosion cannot be recycled, resulting in permanent waste. But metallic aluminium chemical properties vivacity also has certain advantages, for example, Virgin aluminum is very easy to combine with oxygen in the air to generate hard alumina protective layer to prevent further corrosion of the metal inside by air. In addition to recycling smelting aluminum waste, which is cheaper in processing cost and less polluted than the original aluminum smelting, instead of exposing a large number of waste aluminum products to air or acid-base environment to slowly corrode, causing huge pollution, it is better to reasonably recycle and utilize it to reduce the pollution to the whole natural environment.
Some aluminum casting and Broken Bridge aluminum profile, the consumption during use is very small, as long as it is not corroded, it can almost reach 100% recycling, which mainly includes building use aluminum profile, aluminum accessories, aluminum cans lifting box; It is difficult to recycle. In addition to the aluminum chemical containers used in chemical industry (which have been corroded by chemical), there are also food, packaging materials of drugs (often combined with other materials) are difficult to combine aluminum stripping the aluminum makes it more difficult to recover. In addition, extracting pure aluminum from aluminum alloy products also has certain technical difficulties and requires relatively high production technology. The development of modern science and technology is promoted non-ferrous metal materials the recovery smelting process provides technical support, making it possible to recover aluminum waste with high efficiency and low consumption. In the future, we should actively develop efficient and pollution-free recyclable materials and recycling and dismantling technologies for waste aluminum metals to promote the upgrading of recycled aluminum metals.
In fact, some scientific research institutions and enterprises have made great efforts in the recycling and recycling of waste aluminum metals. At present, China has become the second largest producer of recycled aluminum in the world after the United States. The output ratio of recycled aluminum to primary aluminum is about 1:3, although it is far lower than the recycling ratio of recycled aluminum in developed countries (the output ratio of recycled aluminum and primary aluminum in Western developed countries is about 1:2), the results are really worthy of pride. Because as the edge industry of aluminum industry, aluminum recycling smelting started much later than developed countries, and it started only when the consumption of aluminum in social production reached a certain time limit.
Under the concept of energy conservation, low carbon and environmental protection advocated by the state, more and more aluminum development enterprises are now investing in the recycling and refining process of secondary recycled aluminum. Taking chinal as an example, Xiao Yaqing, general manager of chinal, said, compared with other metals, aluminum has the highest recyclability, the largest regeneration benefit, and the recycling rate is above 95%, and the characteristics of recycled aluminum are almost no different from that of primary aluminum. The company is building a renewable aluminum alloy project with an annual output of 200000 tons in Qingdao. After the project is put into operation, it can save 2 million tons of electricity and water compared with virgin aluminum production plants of the same scale, and save 1.2 million tons of solid materials such as bauxite.
Therefore, no matter whether the broken bridge aluminum profile is primary aluminum or recycled aluminum, there is no problem with the quality of doors and windows themselves, or the country will not encourage the recycling of aluminum profiles. I believe that through this article, everyone has a further understanding of the discrimination.
