How are aluminum cans recycled? What is the difference between an aluminum can and a tin can?
In the non-ferrous metal industry, aluminum is in the forefront in terms of reserves, output and consumption. Aluminium, from ore to metal to finished products, is extremely costly and consumes huge energy. The recycling of waste metal aluminum is of great significance in terms of saving resources, shortening the production process cycle, and protecting the environment and improving the environment.
At present, with the increase in production and use, the amount of waste aluminum products is also increasing. And many aluminum products are disposable, and the time from making the finished product to losing its use value is relatively short. Therefore, abandoned aluminum products have become a source of pollution, and how to recycle aluminum products has become a focus of enthusiasm.Take cans as an example to see how recycled aluminum is recycled.
Cans are an important part of China’s recycled aluminum industry. The ideal treatment method for waste cans is to separate the can body from the lid and the pull ring, and then separately smelt to produce the latest alloy. However, due to various reasons, the original form of the recycled waste cans has been damaged, and it will be difficult to transport them to the factory for classification again. Coupled with limited technology, to some extent hindered the recycling of cans. The crushing of the cans is very important. Because the pulverized metal particles can reduce transportation costs and improve the efficiency of ironmaking in the furnace, it also plays an irreplaceable role in deoxidation or metal processing in steel plants.
At present, the recycling of used cans plays an important role in the aluminum product recycling industry. Recycling aluminum resources not only facilitates people’s production and life, but also protects the environment and greatly reduces emissions of carbon dioxide and harmful substances. With the prevalence of the Internet, the emergence of a group of online trading platforms for waste materials has provided customers with a broad platform and expanded the road to recycling aluminum products. Everyone can grasp the recycling of waste materials through such a network of waste materials trading platforms. Trading channels further broaden the recycling path of used aluminum products.
Tin can (1)
① Metal packaging materials have high strength. Therefore, the wall thickness of the packaging container can be very thin, so that it is light in weight, high in strength, and not easily broken.
For storage and transportation, it has good protection for goods.
② The metal packaging material has a unique luster, which is convenient for printing and decoration, making the appearance of the product beautiful and gorgeous. In addition, metal foils and gold-plated films are ideal trademark materials.
③ Metal packaging materials have good comprehensive protection performance. Metal has a low transmittance to water and gas, and is opaque, which can effectively avoid harmful effects such as ultraviolet rays. The comprehensive performance is good, it can maintain the quality of the goods for a long time, and some packaging can be valid for two years. Therefore, it is widely used in the packaging of cans, beverages, powdered foods, medicines, etc.
④ Metal packaging materials are rich in resources and have good processing performance. The recoverable amount of steel on the earth is 1294 × 10 ° t, ranking first, followed by aluminum, which is 68 × 10 ° t. Metal packaging materials can be processed into containers of different shapes and sizes by different methods.
⑤ The production history of metal cans has a long history and the technology is relatively mature. Now it has automated production and high production efficiency.
