wholesale zirconia jewelry Today, in the metal tank manufacturing industry, aluminum materials are mostly used in the production of aluminum two cans (now cola can) aluminum -easy stretching, aluminum easy tearing cover and other products. The material is aluminum plate and aluminum foil. The jar industry has gradually been used in wine cans, high -end gifts, food packaging.
1: The characteristics of aluminum packaging materials
aluminum is a kind of resources with a wealth of silver -white light metal. The aluminum output in the world is second only to steel. Its applications in the metal tank industry are also second only to Riga. The reason why aluminum materials are used in large quantities to make metal tanks. It should have many unique advantages and characteristics for it.
2: The advantages of jarmine aluminum
(1) The density of aluminum is very small, 2.7g/cm, only 35%of steel. Therefore, the quality of the container not only reduces the quality of the container, but also makes the transportation of raw materials more convenient.
(2) The surface of aluminum can naturally generate a dense layer of dense trice oxidation di -aluminum film. The existence of this transparent colorless film can prevent oxidation.
(3) The non -toxicity of aluminum, so the aluminum container is equipped with food safety and hygiene in food, and will not produce metal odor due to heavy metal ions. When using tin -plated horse mouth iron cans The decomposition will cause vulcanization to turn black, and this phenomenon will not occur with aluminum tanks.
(4) Aluminum has a better stretching performance than the Magou iron, which can be made into a shape comparable to the tin -plated metal tank. Its surface is silver and white, and the printing effect of round tea iron can is equally good.
(5) Aluminum -to -light, thermal reflection performance and conduction performance are excellent, which can improve the frozen treatment effect of food tank heating and sterilization boxes. Circular tea tank waste can be recycled and reuse. Prevent public harm caused by waste.
3: The disadvantages of aluminum cans
(1) During the stamping process, aluminum does not absorb magnetic. Packaging materials are difficult to welded by aluminum materials, and aluminum cans can only be manufactured by stamping or bone buckle.
(2) The texture of the aluminum material is soft, and the strength is low compared to the tin -plated board. It is easy to deform due to collision in manufacturing and transportation.
