Alloy Aluminum Coil The Oxide Film Is Not Uniform
The surface of the alloy aluminum coil has the oxide film, which can protect the aluminum alloy, but sometimes we will find that the oxide film will appear uneven. So what's going on? The reasons and prevention of the unevenness of alloy aluminum roll oxidation film are given below.
1. The working area in the slot is too large, and then the color of the oxide film is not consistent.
The method of prevention: oxidation workpiece turns to small and small, can be treated quietly, but when the solution temperature is too low and easy to appear map-like pattern, it appears unnatural.
2, alloy aluminum coil processing are destroyed part of the cladding layer is cut off, the wearing of high quality aluminum alloy, the inner is aluminum, because of the difference is bigger, so after oxidation will produce "vitiligo spot."
Prevention: materials strictly control, reduce or remove the mixed aluminum.
3. The process operation is incomplete in the alkaline etching of the workpiece, the original part of the oxide film, the dirt cannot be divisible; Alkaline etching immediately after treatment, the surface is still alkaline; The artifacts in the transfer process are exposed to foreign objects.
Prevention method: strict guarantee of the integrity of the aluminum alloy process in the production process to produce better products.
The alloy aluminum roll is a jumble of fish, which can make consumers have a headache when they buy it. So here is the selection of the summarized alloy aluminum rolls:
1. Observe the surface and color of the aluminum alloy coil when choosing, whether the appearance is lubricated and the color is bright.
2. There are two sides of alloy aluminum coil and single side. Special attention should be paid to double-sided.
3. The glue seam of the aluminum alloy is neat and neat. When decorating the exterior of the building, it usually has a gap between the plates.
4. The exterior deformation of alloy aluminum coil and the drum are all defective.
Aluminum coil widely used, is often used to make ornaments, also some use adornment building appearance, but in use process will appear some surface contamination, it needs to clean aluminum plate, aluminum plate cleaning? The following is a detailed introduction.
1. Clean the surface of the aluminum coil: rinse with water and pay attention to the large amount of water;
2. Soft cloth wipes the aluminum roll: gently wipe the surface with soft cloth, and the soft cloth with water diluted detergent is needed.
3. Wash the surface of the aluminum coil: rinse the surface with plenty of water and wash away the dirt;
4. Check the aluminum coil thoroughly: clean the area without washing;
5. Wash the surface detergent of aluminum coil: rinse the plate with clean water until all the detergent is washed away;
