The decisive role of aluminum pipe processing technology and galvanizing technology

In fact, there are many types of aluminum coils, and insulation aluminum coil is also a type of aluminum coil. With the continuous improvement of current processing technology, the processing technology of aluminum coils is also constantly enhanced and improved. Silicon has a corrosive effect on hard alloys. Although more than 12% of aluminum alloys are generally referred to as high silicon aluminum alloys, diamond cutting tools are recommended, but this is not absolute. The increasing silicon content also gradually increases the destructive power of the cutting tools, Therefore, some manufacturers recommend using diamond cutting tools when the silicon content exceeds 8%.

Aluminum alloy with a silicon content between 8% and 12% is a transitional zone, which can use both ordinary hard alloys and diamond tools. However, hard alloys used for aluminum pipes should use tools with PVD (physical coating) method, which do not contain aluminum elements and have a smaller film thickness.

Due to the PVD method and the small thickness of the film layer, it is possible for the tool to adhere to a sharp cutting edge (otherwise, sufficient passivation is required to prevent the film layer from abnormally growing at the cutting edge, which will not be sharp when cutting aluminum alloys). However, the film layer data containing aluminum may cause the blade film layer to have an affinity with the workpiece material, damaging the bonding between the film layer and the tool substrate. Due to the fact that the superhard coating is mostly a compound of aluminum, nitrogen, and titanium, It may be caused by a small amount of detachment of the hard alloy substrate along with the film layer, resulting in blade breakage.

The chip holding space of the cutting tool should be large. For an aluminum tube, it is recommended to use 2 teeth, with a large front and rear angle (such as 12 ° -14 °, including the rear angle of the end teeth). If only the general milling surface is used, an indexable surface milling cutter with a 45 ° main deviation angle can be used, and a blade specifically designed for processing aluminum alloy should be used to achieve better results.

The small long pipes adjacent to the galvanized pipes can be welded with flat iron. The decisive role of aluminum pipe galvanizing technology is actually that many products are interchangeable. By changing the specifications and sizes of aluminum pipes, I can turn them into different wire mesh products, or welding them with small square pipes. The main product of aluminum pipes is constantly innovating and improving, successfully launching a variety of wire mesh products, with more and more diverse types.

The surface treatment process plays a decisive role in the lifespan of aluminum pipes. Therefore, when galvanizing aluminum pipes, anti-corrosion work should be done well. Before galvanizing, it should be thoroughly pickled and there should be no pre oxidized iron slag. Otherwise, galvanizing cannot ensure that the zinc layer can adhere well to the surface of the steel grid, and the zinc layer should not be too thin or too thick. Aluminum pipes are now used in many places, but many people still do not know which fields and ranges this product can be used in.

Many people do not know the antioxidant properties and are also a type of metal material. Why can this metal material have such properties? In fact, this metal material is treated differently in the production process. The surface treatment method for steel grilles is hot-dip galvanizing, and aluminum pipes.
