Application of steel drums
Steel drums are one of the traditional containers and play an important role in traditional containers. Steel drums have evolved from the function of temporarily storing the contents to today's industrial packaging, sales packaging, transportation packaging, etc.; from production to circulation and consumption, they have formed a consistent flow container, which has become a means of long-term preservation of the contents. Work and life have brought great changes and progress.
Although the application of steel drums has only a history of more than 100 years, with the development of the modern steel industry, it provides a large amount of steel for various sectors of industry and agriculture, which has become the basis of modern production in various sectors, and is widely used in industrial product packaging, transportation packaging and In the sales packaging, steel drums have become one of the main ones. At present, Japan and European countries have about 14% of steel, second only to low and plastic packaging, occupying the third place, while the United States consumes more steel than plastic, accounting for about the second place. my country's steel accounts for about 8% of the total, second only to plastics. Today, with the rapid development of various packaging technologies, new types are constantly emerging, and the competition is fierce. The application of steel drums in some aspects has been partially replaced by plastics or composite materials. However, due to the excellent comprehensive properties of steel, and The resources are extremely rich, so the steel still maintains its vitality, and its application forms are more diverse. In particular, it has found a place in the field of composite materials, and it has become the main barrier material layer in composite materials, such as the successful application of metallized composite films.
2. Performance characteristics of steel drums Although the application of steel drums has only a history of more than 100 years, it has developed rapidly and has a wide variety of products. It is widely used in industrial product packaging, transportation packaging and sales packaging, mainly because steel drums have The following performance characteristics:
1. The steel drum has excellent mechanical properties and high strength, so the steel drum container can be made into a packaging container with thin wall, high compressive strength and not easy to be damaged. In this way, the safety of the packaged product has a reliable guarantee, and it is convenient for storage, transportation, loading and unloading and use.
2. The processing performance of the steel drum is excellent, the processing technology is mature, and it can be produced continuously and automatically. Steel drums have good ductility and strength, and can be rolled into sheets and foils of various thicknesses. The sheets can be punched, rolled, stretched, and welded to form packaging containers of different shapes and sizes.
3. The steel drum has excellent comprehensive protection performance. The water vapor transmission rate of steel is very low, and it is completely opaque, which can effectively avoid the harmful effects of ultraviolet rays. Its gas-barrier, moisture-proof, light-shielding and quality-preserving properties greatly exceed those of other types such as plastic and paper. Therefore, steel drums can maintain the quality of goods for a long time, which is especially important for food packaging.
4. The steel drum has a special metallic luster, and it is also easy to print and decorate, which can make the product look luxurious and beautiful, beautiful and marketable.
5. Steel drums are rich in resources, and energy consumption and cost are relatively low. And it has repeatability and recyclability, which is ideal green in terms of environmental protection.
Although steel drums have the above characteristics, they also have shortcomings. Mainly: poor chemical stability, corrosion resistance is not as good as plastic and glass, especially ordinary steel is easy to rust. Therefore, steel drums must be covered with a layer of anti-rust substances on the surface to prevent corrosion and damage from the outside world and the packaged materials, and at the same time to prevent the contamination of goods by harmful substances in steel, such as steel containing heavy metals to varying degrees. Merchants such as Pb, Sn, etc., these heavy metal ions can interact with commodities, especially food, which not only pollutes food, but also causes great harm to human body.
