Galvanized barrel has two galvanizing processes, hot galvanizing and cold galvanizing. However, the galvanized barrel produced by any process has a galvanized layer on the exterior. Can protect the galvanized barrel itself from external corrosion. Then the service life is guaranteed. Iron buckets are prone to react directly with chemical elements in the air. Then there is a phenomenon such as rust. The difference between the two is that galvanized drums have a protective layer that can increase the service life of the limited, while iron drums have a relatively short service life and are prone to rust.
The tin barrel has good prospects for development and application, and can be used as a substitute for metal, glass, and ceramic packaging containers. Compared with these packaging containers, steel-plastic composite barrels have good advantages. Its main characteristics are: because paper is the main raw material, it is easy to recover and dispose; it has excellent maintenance performance, can be waterproof, moisture-proof, and heat-insulating; It can be used for food packaging; it can be filled with a variety of products with low noise during filling; it can withstand positive and negative pressures and can be used in vacuum or nitrogen-filled packaging.https://www.fhpails.com/
