How To Solve The Problem of 5052 Aluminum Plate Dyeing?
1. Control the Thickness of the Oxide Film
Oxide film refers to the thickness, porosity, transparency, and so on of aluminum sheet film. The thickness of the 5052 aluminum plate middle film is maintained at more than 10um, porosity, and transparency, and the best dyeing quality can be obtained.
2. Select the Raw Materials of the 5052 Aluminum Sheet
Usually, high-purity aluminum, aluminum magnesium, and aluminum manganese alloy after anodizing in the production process, its dyeing function is the best and can be dyed into a variety of colors. Plates with heavy silicon or copper, can only be dyed dark black during the dyeing process, and the color is relatively monotonous.
3. Control the Temperature of the Dyeing Solution
5052 aluminum plate dyeing is divided into cold dyeing and hot dyeing. The use of cold dyeing, in the production process with longer use time, dyeing uniformity is better. Hot dyeing is relatively short in use, but it is difficult to control the color. The temperature of hot dyeing is usually 40-60℃. If the temperature is too high, it will reduce the adsorption of the stain, which is easy to cause the surface of the aluminum plate to bloom.
4. Master the Concentration of the Dye Solution
The concentration of 5052 aluminum plate is related to dyeing. If the aluminum plate is colored light, the concentration can be lower, and the dark color can be higher. Usually, aluminum sheet material dyeing lighter color is 0. It’s 1-0. 39g/L, light color is 1g/L, deep color is 3-5g/L, dense dyeing is 10-15g/L, if the dyeing concentration is high, it will lead to uneven color or floating color, and “color flow” is easy to appear in the cleaning and closing process.
To enhance the adsorbability of the dyeing, a low concentration of color will be used to extend the dyeing, so that the dye molecules can penetrate more evenly into the depth of the oxide film hole, making the color of the dyeing more harmonious and firm.
What Are The Characteristics of 5052 Aluminum Plate Aluminum Magnesium Alloy Welding?
1. Strong Reduction Ability
Aluminum has a strong affinity with oxygen, and aluminum is easily synthesized by oxidation in the air. A1203 film thickness is about 00.1μm. The melting point of A1203 is as high as 2050 ° C, much higher than the melting point of aluminum and aluminum alloys (500-600 ° C). In the welding process, the oxide film prevents good bonding between the metals, which is easy to cause slag inclusion. The alumina film can also absorb water and promote the formation of pores in the weld.
2. High Thermal Conductivity and Specific Heat Capacity
The thermal conductivity and specific heat capacity of aluminum and aluminum alloys are more than twice that of carbon steel and low alloy steel. During the welding process, a large amount of heat is rapidly transferred to the base metal. Therefore, when welding aluminum and aluminum alloys, in addition to melting the metal, it is unnecessary to consume other parts of the metal.
3. Large Tendency of Hot Cracking
The coefficient of linear expansion of aluminum is about 22.9 x10-6/ ℃, iron is 11.7 x10-6/ ℃, and the coefficient of linear expansion of aluminum and aluminum alloy is about twice that of carbon steel and low alloy steel. When aluminum solidifies, the volume shrinkage rate is large, reaching 6.5%, while iron is 3.5. Therefore, aluminum and aluminum alloys make it easy to produce shrinkage holes, shrinkage porosity, thermal cracks, and high internal stress during welding.
4. High Stomatal Sensitivity
Liquid pools of aluminum and aluminum alloys readily absorb gases such as hydrogen. A large number of gases dissolved at high temperatures do not have time to settle during the cooling and solidification process after welding. Pores form when they gather in the weld. The water in the arc column atmosphere, the water adsorbed by the oxide film on the surface of the welding material, and the base material are important sources of hydrogen in the weld.
5. No Color Change During Solid Liquefaction
When aluminum and aluminum alloy welding pool metal changes from solid to liquid, the color change is not obvious, which brings inconvenience to the welding operation.
6. Single Phase
5052 aluminum plate aluminum is a face-centered cubic lattice, with no allotrope, and no phase change when heating and cooling, weld grain is easy to coarse, and can not be refined through phase change.
The welding characteristics of aluminum alloy 5052 aluminum plate are introduced above. 5052 aluminum plate has good friction stir welding performance, dynamic recrystallization of weld area, weld grain refinement, and weld can achieve 0℃ to 180℃. The strength of the welded joint can reach or exceed that of base material by optimizing process parameters.
