The first step, 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. In 1911, the Swiss confectionery company began wrapping chocolate in aluminum foil, gradually replacing tinfoil in popularity. In 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. Chemical composition: The alloy grades of aluminum foil for heat exchange fins mainly include 1100, 1200, 8011, 8006, etc. 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. In my country 10 years ago, the aluminum foil used for air-conditioning heat exchangers in foreign countries about 15 years ago was all uncoated aluminum foil. Even at present, about 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 ...
The main alloying elements of 6063 aluminum alloy are magnesium and silicon. It has excellent machining performance, excellent weldability, extrudability, and electroplating performance, good corrosion resistance, toughness, easy polishing, coating, and excellent anodizing effect. It is a typically extruded alloy widely used in construction profiles, irrigation pipes, pipes, poles and vehicle fences, furniture ...
hot ingot rolling First, the aluminum melt is cast into a slab, and after homogenization, hot rolling, cold rolling, intermediate annealing and other processes, it is continued to be cold rolled into a sheet with a thickness of about 0.4~1.0 mm as a foil blank (casting → hot rolling billet → cold rolling → foil rolling). In the ingot hot rolling method, the hot rolled billet is first milled to remove defect ...
Single-sided carbon-coated aluminum foil is a breakthrough technological innovation that uses functional coatings to treat the surface of battery conductive substrates. Carbon-coated aluminum foil/copper foil is to uniformly and finely coat dispersed nano-conductive graphite and carbon-coated particles on aluminum foil/copper foil. It can provide excellent electrostatic conductivity, collect the micro-current ...
Coiling defects mainly refer to loose, layer channeling, tower shape, warping and so on. Aluminum foil roll during the winding process. Because the tension of aluminum foil is limited, enough tension is the condition to form a certain tension gradient. Therefore, the winding quality ultimately depends on good shape, reasonable process parameters and suitable precision sleeve. It is ideal to obtain tight coils ...
For the capsule shell, because it is made of aluminum, aluminum is an infinitely recyclable material. Capsule coffee generally uses an aluminum casing. Aluminum is the most protective material at present. It can not only lock the aroma of coffee, but also is light in weight and high in strength. At the same time, aluminum protects the coffee from foreign substances such as oxygen, moisture and light. For cof ...
Have you ever eaten grilled fish or sixty-six, and you must have seen this tin foil, but have you seen this thing used in indoor spaces? That's right it's called decorative foil (decorative tin foil). Generally, it can be used on walls, top cabinets, or art installations. Aluminum foil (tinfoil paper) can be kneaded out of wrinkles, resulting in a very unique and abstract reflective texture, and the appeara ...
