প্রথম ধাপ, smelting A large capacity regenerative melting furnace is used to convert the primary aluminum into aluminum liquid, and the liquid enters the casting and rolling machine through the flow groove. During the flow of the liquid aluminum, the refiner Al-Ti-B is added online to form a continuous and uniform refining effect. The graphite rotor degassing and slagging on line at 730-735°C, forming a con ...

Aluminum foil packaging development history: Aluminum foil packaging began in the early 20th century, when aluminum foil as the most expensive packaging material, only used for high-grade packaging. ভিতরে 1911, the Swiss confectionery company began wrapping chocolate in aluminum foil, gradually replacing tinfoil in popularity. ভিতরে 1913, based on the success of aluminum smelting, the United States began to produce ...

Coated aluminum foil is formed after surface treatment on the basis of non-coated aluminum foil. In addition to the chemical composition, mechanical properties and geometric dimensions required by the above non-coated aluminum foil, it should also have good shape and shape. coating properties. 1. Plate type of aluminum foil: First of all, the production process of coated aluminum foil requires that the alum ...

1. রাসায়নিক রচনা: The alloy grades of aluminum foil for heat exchange fins mainly include 1100, 1200, 8011, 8006, ইত্যাদি. From the perspective of use, air conditioners do not have strict requirements on the chemical composition of aluminum heat exchange fins. Without surface treatment, 3A21 aluminum alloy has relatively good corrosion resistance, high mechanical properties such as strength and elongation, ...

1. Uncoated aluminum foil Uncoated aluminum foil refers to aluminum foil that has been rolled and annealed without any form of surface treatment. আমার দেশে 10 বহুবছর পূর্বে, the aluminum foil used for air-conditioning heat exchangers in foreign countries about 15 years ago was all uncoated aluminum foil. এমনকি বর্তমানেও, সম্পর্কিত 50% of the heat exchange fins used in foreign developed countries are still uncoated ...

Foil bags are not toxic. The inside of the aluminum foil insulation bag is a soft insulation material such as foam, which meets the food safety regulations. Aluminum foil has excellent barrier properties, good moisture resistance, and thermal insulation. Even if the heat reaches the middle PE airbag layer through the inner aluminum foil layer, heat convection will be formed in the middle layer, and it is not easy ...
