What Is Manufacturing Process of Anodized Aluminium Strip

 The anodized aluminium strip production process: mechanical polishing of aluminum coils-degreasing - water washing - chemical polishing - water washing - anodizing - water washing - closing - mechanical brightening-slitting.

Remark 1: Chemical polishing products: Aluminum-alkali polishing liquid

Remark 2: Anodizing products: aluminum anodizing liquid

Remark 3: Closing products: Aluminum coil coloring closing liquid

Aluminum strip anodizing dyeing process

1. Aluminum coil pretreatment

Aluminum strip roll are stained with more grease, a small amount of abrasives, dust and defective oxide films during repeated machining. These substances have poor electrical conductivity and cannot be anodized, so they need to be processed in advance. The method is to soak the aluminum in carbon tetrachloride, trichlorethylene, gasoline or toluene, rinse it with a brush, then air-dry it, then soak it in water, and wash it repeatedly. After removing oil, rinse immediately with hot water. If a black film appears on the surface, soak it in 32% nitric acid solution for 20 seconds to remove the black film, and finally rinse with cold water.

2. Anodized aluminum strip

Sulfuric acid electrolyte manufacturing: The ratio of 18-20kg sulfuric acid and 80-82kg deionized water solution is about 1.125-1.140. Sometimes a small amount of oxalic acid is added to the sulfuric acid electrolyte to obtain a good anodizing film.

Anodizing process: Aluminum and its alloys form an oxide film on aluminum products (anode) under the action of applied current under corresponding electrolytes and specific process conditions. Anodizing usually refers to sulfuric acid anodizing unless otherwise specified.

3. Alumina coil dyeing

Dyes are divided into inorganic dyes and organic dyes. Inorganic dyes are mainly composed of inorganic salts. When dyeing, the aluminum is soaked in A and B colored compounds to achieve the dyeing purpose.

4. Precautions for anodizing treatment

After the aluminum coil is treated with washing oil, the aluminum coil should be anodized immediately and should not be left for too long.

When purchasing raw materials and dyes, you should choose products with high purity, because generally the dyeing effect will be poor if there are more impurities.

In addition to anodized aluminum strips, Haomei Aluminum also has aluminum moulding strips, aluminum flashing roll, painted aluminum coil,etc. Welcome to leave message below to inquire what you need.

Aluminum Plate for Special Vehicles

 Aluminum alloy, with its unique advantages of low density, corrosion resistance, energy saving and environmental protection, is gradually used in large quantities in special vehicles and has become the main material for lightweight.

Tanker Truck

Compared with ordinary carbon steel and stainless steel tank trucks, aluminum alloy tank trucks can not only significantly reduce the weight of the vehicle, improve transportation efficiency, but also extend the service life of the tank.

Its corrosion resistance is more than 70% higher than that of traditional carbon steel. This feature greatly reduces the maintenance costs related to the tank. The internal cleanliness of the tank is high, and it has good energy saving and environmental protection effects.

Aluminum alloy 5083, 5454 and 5182 are currently commonly used tanker aluminum sheets. They can be used to make tanker body, baffle and tanker head. The aluminum alloy tank truck can load oil, gasoline, chemicals, cement and other dense materials.

Vans

Aluminum alloy vans mainly include aluminum alloy van semi-trailers and aluminum alloy wing opening transport vehicles. According to the usage rate of aluminum alloy in the vehicle, it can be divided into all-aluminum alloy vans and steel-aluminum hybrid vans.

An all-aluminum alloy van means that the frame and body are made of aluminum alloy; a steel-aluminum hybrid van means that part of the vehicle structure is made of aluminum alloy, such as the carriage body is made of aluminum alloy while the frame is still made of steel. The aluminum alloys available for van trucks are aluminum plates, aluminum alloy profiles, aluminum honeycomb panels, aluminum castings, etc. Due to the advantages of high strength and easy molding of aluminum alloy profiles, aluminum alloy profiles are preferred for manufacturing.

Aluminum alloy vans have long been popular in European and American markets. Because of its light weight, large loading space, beautiful appearance, and the ability to print advertisements on the surface, it occupies a leading position in the US market. The alloys used in aluminum alloy profiles for containers mainly include 6061, 6082, 6351, 6005, 6063 and 6060, among which 6061 and 6082 alloys account for more than 90%. Asia and the United States mainly use 6061 alloy, while European vans mainly use 6082 alloy.

Refrigerated trucks

Refrigerated trucks are closed van transport vehicles used to transport frozen or fresh-keeping goods, including bread-type refrigerated trucks, van-type refrigerated trucks and semi-trailer refrigerated trucks. The biggest difference in the relationship between properties and temperature between aluminum and steel is that steel has low-temperature brittleness, while aluminum and aluminum alloys do not. When the temperature decreases, while the strength and performance of aluminum and aluminum alloys increase, the plasticity also increases as the temperature decreases. Therefore, aluminum alloys become good materials for low-temperature equipment.

Haomei Aluminum provides 5083, 5754, 5454, 5059 and 5182 aluminum alloy for special vehicles, especially fuel tankers, semi trucks, LNG tank,etc. Welcome to leave message below to inquire what you want.

1050 Aluminum Circle for Making Cookware

 Aluminum circle discs are round aluminum sheets processed on the basis of aluminum plates. It is divided into pure aluminum discs, alloy aluminum discs, thin aluminum discs, and medium-thick aluminum discs. The common tempers are H24, H22, O and H18. It is suitable for stretching and spinning, and can produce kitchenware, electrical appliances, LED lamp casings and other products.

1xxx pure aluminum circles are commonly used in hin plate processing parts, deep drawing or spinning concave utensils, clock surfaces and disks, nameplates, kitchen utensils, reflaective equipment, heat sinks, bottle caps, and other deep stamping products. 3 series aluminum discs are used for processing parts that require good formability, high corrosion resistance and good weldability, such as kitchen utensils, food and chemical product processing and storage devices, liquid tanks,etc.

Cookware

Many kitchen utensils choose aluminum discs with low density and light weight. Take the pots we use every day as an example. We use a new rolling technology to make the pots into a three-layer process. The first layer is made of stainless steel, the second layer is made of 1050 aluminum circle, and the third layer is made of iron.

The pot treated with layer technology not only has the toughness of steel, the long life of iron, and the light density of aluminum, but is integrated into three advantages. This is one of the reasons why aluminum discs are increasingly used in the field of kitchenware.

Road sign

The field of signage is one that we are exposed to quite a lot in our daily life. For example, the circular signs we see on the road are generally processed using aluminum discs. For example, the no-parking signs we see in garages, or some speed measuring or speed limit signs we see on the highway, are all made of thicker aluminum discs for post-reinforcement processing. This is also one of the core application areas of aluminum wafers.

Electronic backplane field

The bottom plate inside the back panel of our monitor or TV is made of aluminum circle for copper coating. The product displayed after processing is the application of electronic backplane.

Aluminum container

This is a newly developed field. For example, containers for liquid nitrogen are stamped with a circle aluminum. For this field, 6061 aluminum circles or 5052 aluminum circles are generally used. Because these two types of aluminum circles contain magnesium, they are not prone to chemical reactions with the liquid inside. At the same time, the rolling performance of the 6 series and 5 series is better than that of the 3xxx and 5xxx aluminium discs.

What Are Special Requirements of Aircraft Aluminum Conditioner

 

Special application environment of aircraft air conditioning system

Compared with ground air conditioning, aircraft air conditioning systems mainly face the following three special environments:

1. Complex and changeable atmospheric conditions at flying altitudes

During flight, aircraft will experience atmospheric environments at different altitudes, and parameters such as temperature, pressure, and humidity are constantly changing, which increases the adaptability requirements of the air conditioning system.

During climb and landing, the ambient temperature gradient is large, which poses a challenge to the system's cooling capacity. At cruising altitude, the temperature is lower but the air is thinner, and the heat transfer conditions become worse, which also brings design problems to the heat exchange components.

2. The impact of high-speed airflow

When an airplane flies at near-sonic or supersonic speeds, the speed of the external airflow is very large, which produces strong impact pressure on the cabin. This requires the air conditioning system and the entire cabin to have sufficient pressure carrying capacity. At the same time, strong external airflow will also cause instability in the heat exchange process of the system.

3. Extreme space and weight restrictions

The airplanes have very strict space and weight requirements for system hardware. Air conditioning equipment must be highly compact and lightweight. This places strict requirements on the design size and material selection of heat exchange components. In summary, the special environment requires that the aircraft air-conditioning system must be highly sealed, structurally solid, and have strong pressure-bearing capacity. It also needs to be small in size, light in weight, reliable in operation, and capable of adapting to environmental changes.

Main components of aircraft air conditioner

The aircraft air conditioning system mainly consists of a compressor, condenser, expansion device, evaporator, fan, air filtration system, etc., which is similar to the ground air conditioning system. But all its power comes from aviation engines, which has unique features:

1. Dedicated aviation compressor

Compressors usually adopt a turbofan structure, which has a large compression ratio and can achieve a wide range of flow adjustment by adjusting the geometric size of the turbofan. The compressor is directly installed on the aircraft engine and uses the engine to output power.

2. Compact heat exchange components

Condensers and evaporators often use compact heat exchangers such as plate-fin type and tube-fin type, which can enhance heat transfer in a limited space. At the same time, the influence of high-speed airflow needs to be considered for fluid dynamic design.

3. Lightweight fan structure

Use composite materials to make fan blades into lightweight structures to reduce rotating mass and power loss. The blades need to withstand high-speed rotational stress.

4. High-efficiency air filtration system

The multi-stage filter combination achieves efficient interception of dust, bacteria, and viruses. It is also of small size, light weight and easy replace of filter. This requires the close cooperation of materials, fluid dynamics, heat transfer and other disciplines.

Aircraft aluminum conditioner

The aluminum alloys used in aircraft air conditioners need to be lightweight, high-strength, corrosion-resistant, and have good thermal conductivity to ensure the normal operation of the aircraft air-conditioning system and the comfort of passengers. The common choices are 2xxx and 7xxx aluminum alloys like matweb aluminum 7075.

In aircraft air conditioning systems, aluminum alloys may be used to manufacture various components, such as condensers, evaporators, fan blades, etc. These parts need to withstand harsh environments such as high temperature, high pressure and corrosion, so they need to use high-quality aluminum alloy materials.

Commonly used aluminum alloys include 2024 aluminum alloy and 7075 aluminum alloy. 2024 aluminum alloy is a high-strength, corrosion-resistant aluminum alloy material with good mechanical properties and processing properties, and is widely used in aircraft manufacturing. 2024 t351 is its popular temper.
