Pickling treatmen the purpose is to remove the black corrosion products left on the product surface after corrosion, so as to obtain a bright metal surface. Extinction treatmen the purpose is to make the surface of aluminum materials or aluminum products dull and form a non gloss surface after anodizing treatment to form spot
Alkali washing Generally, the surface of the aluminum plate supplied by the aluminum sheet processing plant contains a certain amount of oil. The oil and oxide film have an impact on the sand mesh disposal. In the production of PS plate, hot alkali is often used to wash the aluminum plate for surface disposal. Alkaline solution is generally used to remove oxide film and oil. The ratio of

1. Anodizing: This is a common surface treatment method for industrial aluminum profiles. The principle is to form an oxide film on the surface of the profile. The advantage is that it can increase the profile\'s anti-corrosion and wear resistance, and has an insulating effect. It is suitable for a variety of industrial production fields and can
Etching: Roughening of the surface of a metal by overall or selective dissolution in acid or caustic media. Pickling: Removal of a thin surface layer of a metal by chemical action, mainly by treatment in a caustic solution. Coating Coating (organic): Method in which a coating material is applied on a metallic substrate. This process includes
aluminum surface is blasted with grit, steel parti- cles become embedded, and unless they are re- moved by a subsequent chemical treatment, they will rust and stain the surface. It is good practice to remove particle contamination with a nitric acid pickle to prevent degradation of corrosion resistance. A 20-min soak in 50% nitric acid
Let\'s talk about the surface treatment method of decorative aluminum plate. There are currently no more than three methods for surface protection of decorative aluminum plates: (1) Anodizing, aluminum alloy doors and windows have been introduced in the 1950s, and it is still a common surface treatment measure for aluminum doors and windows and

At present, the commonly used surface treatment methods of aluminum plates are mainly the following five types. 5052 aluminum coil sheet. 1. Powder electrostatic spraying Electrostatic spraying uses the principle of high voltage electrostatic corona electric field. The metal diversion cup on the spray gun head is connected with high voltage
2. The surface treatment method of decorative aluminum sheet (1) Anodizing: Aluminum alloy doors and windows have been introduced in the 1950s, and it is still a common surface treatment measure for aluminum doors and windows and colored aluminum sheets; (2) Acrylic resin for electrophoresis after anodic
Brushed aluminum strips are usually used for decoration and channel letters. The brushed lines are usually clear and regular, horizontal to the edge of the strips. The purpose of brushing an aluminium strip is to make its surface more beautiful and decorative. Although the surface is not smooth, it becomes rather even during the brushing

It is good practice to remove particle contamination with a nitric acid pickle to prevent degradation of corrosion resistance. A 20-min soak in 50% nitric acid
3: multi-tone surface treatment. Nowadays, in order to better use the stucco aluminium sheet, various color treatments naturally occur, so that the color of the embossed aluminum plate can be further improved, and the decoration effect is better. We hope that the above-mentioned the surface treatment of the stucco aluminum sheet can help you
Embossed Aluminium coil also called stucco embossed aluminium coil, is a kind of aluminum coil which forms a variety of decorative pattern on the surface after calendering processing. It is widely used, mainly in packing, building, curtain wall, etc. The sandblasting method is very suitable for the surface treatment of the embossed aluminum
With the continuous development of powder coating technology, electrostatic powder coating is widely used in the field of surface treatment of aluminum profile due to its unique process characteristics.The main features of the recovery rate of more than 95%, no pollution, no preheating at room temperature conditions can be powder coating, can form a thick film layer at one time, no

Aluminum substrate is a composite material of resin, aluminum and copper foil.Resin and aluminum, copper foil thermal expansion coefficient is very different, therefore, in the external force, under the action of heat, produce uneven distribution of internal force in the plate.If water molecules and some low molecular matter remain in the pores
Aluminum alloys are divided into two major categories: wrought and casting alloys. A further differentiation for each category is based primary on mechanism of property development. Many Aluminum alloys respond to thermal treatment based on phase solubility. These treatments include solution heat treatment, quenching and precipitation, or age
The surface treatment of die-cast aluminum sheets generally includes: powder spraying (ie, powder coating), baking paint, fuel injection, oxidation, sand blasting, electroplating, and the like. According to the thickness and finish of the surface treatment of the

Surface treatment methods for an aluminum stucco sheet include mill finish, anodizing and color coating. Each has its own functions and applications. Mill finish stucco embossed aluminium sheets have no extra treatment for the surface. This method is applied to stucco sheets for general uses, like fridge inner wall cladding, air conditioners
1. Electrophoresis painting: a surface treatment method adopted mostly in Japan. This brings out the smooth part of the aluminium sheet surface and enhances the corrosion resistance of the sheet. 2. Powder electrostatic spraying: The main feature is to enhance the corrosion resistance of the aluminum plate, especially resistance to some acid
The surface of a piece of aluminum or aluminum alloy is decorated with a novel \"lizardskin\" appearance by passing an alternating electrolytic current at 5 to 50 volts between said piece used as an electrode, and a second electrode, both electrodes being submerged in an aqueous electrolyte bath containing 0.1 to 20 grams/liter of a suitable acid and 0.1 to 20 grams/liter of a polyfluorinated
2. Surface treatment method. Usually using a dry process, that is, the aluminum hydroxide is placed in high-efficiency kneading equipment (such as a high-speed mixer) for mixing. The modifier is sprayed on the aluminum hydroxide directly or diluted with a small amount of inert solvent, and then fully mixed. Finally dry at a certain temperature.
Aluminum heat treatment is a process by which the strength and hardness of a specific subset of aluminum alloys, namely the wrought and cast alloys that are precipitation hardenable, are increased. Precipitation hardenable aluminum alloys include the 2XXX, 6XXX, 7XXX and 8XXX series. In addition, annealing may be required for parts that have
