Aluminum Plate Cleaning Steps
Jun 22, 2017

Aluminum, refers to the use of pure aluminum or aluminum alloy material through the pressure processing (shear or sawing) to obtain cross-section rectangular, uniform thickness of the rectangular material

Classification of aluminum

Aluminum classification International used to the thickness of 0.2mm above, 500mm below the width of 200mm, the length of 16m or less of the aluminum material called aluminum sheet or aluminum sheet, 0.2mm below the aluminum foil, 200mm width within the row of material or Strip (of course, Aluminum Sheet with the progress of large equipment, the widest can do 600mm of the row of materials are more).

definition

Aluminum is usually divided into two categories:

1. According to the alloy composition is divided into:

High purity aluminum (made of high purity aluminum over 99.9)

Pure aluminum (the composition is basically made of pure aluminum)

Alloy aluminum (composed of aluminum and auxiliary alloy, usually aluminum, aluminum, aluminum, aluminum and magnesium, and other series)

Composite aluminum plate or welding plate (through a variety of materials to get a special means of composite aluminum material)

Aluminum-clad aluminum (aluminum-coated aluminum sheet for special use)

use

1, lighting 7, signs, nameplate, luggage 8, car interior and exterior decoration 9. Interior decorations: such as the interior of the car, the interior of the car, Photo frame 10, household appliances: refrigerators, microwave ovens, audio equipment, etc. 11. Aerospace and military aspects, such as China's large aircraft manufacturing, Shenzhou spacecraft series, satellite and so on. 12, mechanical parts processing 13, mold manufacturing 14, chemical / insulation pipe coating.

classification

Aluminum Sheet In the aluminum alloy grade is representative, the following 7075T651 aluminum plate as an example. The first 7 represents aluminum and aluminum alloy - aluminum zinc alloy. Aluminum and aluminum alloy group is divided into nine categories. One of the 1,3,5,6,7 series of aluminum, aluminum-based, Aluminum Sheet other series in the actual use of the use of less chance.

The first category: 1 series: industrial pure aluminum

The second category: 2 series: aluminum alloy

The third category: 3 Series: aluminum alloy

The fourth category: 4 Series: Al-Si alloy

The fifth category: 5 series: aluminum magnesium alloy

The sixth category: 6 series: aluminum magnesium silicon alloy

The seventh category: 7 Series: aluminum zinc magnesium copper alloy

The eighth category: 8 series: other alloys

The ninth category: 9 Series: spare alloy

Aluminum plate. International used to the thickness of 0.2mm above 500mm, 200mm width above the length of 16m or less of the aluminum material called aluminum sheet or aluminum sheet, Aluminum Sheet 0.2mm below the aluminum foil, 200mm within the width of the strip or bar (Of course, with the progress of large equipment, Pan bamboo can be the widest 600mm of the row of materials are more). Aluminum rods, diameter: 3-500mm aluminum tubes, thickness: 2-500mm under: aluminum, aluminum, aluminum rods Panzhu theoretical calculation formula. (Kg) = 0.0000028 × thickness × width × length aluminum tube weight (kg) = 0.00879 × wall thickness × (outer diameter - wall thickness) × length aluminum rod (kg) Weight calculation formula (kg) = diameter × diameter × length × 0.0000022

Brushed aluminum: repeatedly with sandpaper to scrap the line of aluminum manufacturing process, the main process is divided into de-ester, sand mill, washed three parts. In the aluminum wire drawing process, the anode treatment after the special film technology, can make the surface of the aluminum plate containing a metal composition of the film layer, clearly show each fine silk marks, Aluminum Sheet so that the metal matte glow in the fine hair Silk glossy.

Aluminum plate: the aluminum plate placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, under specific conditions and external current under the action of electrolysis and the formation of aluminum. Anodic aluminum plate oxidation, the surface of the formation of alumina thin layer, the thickness of 5 to 20 microns, hard anodic oxide up to 60 to 200 microns.

PS aluminum (advertising aluminum plate, also known as printing zinc plate, newspaper cardboard): the back of the printed pattern thickness of 025 or 03 material of the aluminum plate.

Mirror aluminum: refers to the rolling, grinding and other methods to deal with, so that the surface of the plate surface mirror effect of aluminum.

Embossed aluminum can also be called aluminum embossing board: belong to the aluminum plate on the basis of rolling through the surface and the formation of a variety of patterns of aluminum products, Aluminum Sheet more widely used, mainly used in packaging, construction, curtain wall and so on.

Aluminum specific cleaning steps are as follows:

1, first with plenty of water to wash the surface;

2, the use of soaked with water diluted detergent soft cloth gently wipe the board surface;

3, and then a lot of water rinse the board, Aluminum Sheet the dirt washed away;

4, check the board surface, for no clean place with detergent focus on cleaning;

5, with water rinse the board until the detergent all washed away.

CAUTION: Do not clean the hot plate (when the temperature exceeds 40 ° C), because the moisture is too fast to be harmful to the board paint!
