What is brushed aluminum sheet?
According to the needs of decoration, drawing can be made into straight lines, random lines, threads, corrugations and spiral lines.
Straight line drawing It refers to machining straight lines on the surface of aluminum plate by mechanical friction. The utility model has the double functions of brushing the scratches on the surface of the aluminum plate and decorating the surface of the aluminum plate. There are two kinds of straight line drawing: continuous line and intermittent line. The continuous wire pattern can be obtained by continuous horizontal straight-line friction on the surface of aluminum plate (such as manual grinding under the condition of existing device or grinding on aluminum plate with wire brush clamped by planer). By changing the diameter of the steel wire of the stainless steel brush, the lines of different thickness can be obtained. Intermittent silk patterns are usually made on a brush or a scratch machine. Production principle: two groups of differential wheels rotating in the same direction are used, the upper group is the fast rotating grinding roller, the lower group is the slow rotating rubber roller, and the aluminum or aluminum alloy plate passes through the two groups of roller wheels, which are brushed with fine intermittent straight lines.
Random pattern drawing Under the high-speed running copper wire brush, a kind of matte wire pattern with no regular and obvious lines is obtained by moving the aluminum plate forward and backward. This kind of processing has higher requirements on the appearance of aluminum or aluminum alloy plates.
Ripple Generally, it is made on a brush machine or a striation machine. Using the axial movement of the upper group of grinding roller and the surface grinding of aluminum or aluminum alloy plate, the wavy pattern is obtained
Swirling stripes It is also called rotary polishing. It is a kind of silk pattern obtained by rotary polishing on the surface of aluminum or aluminum alloy plate with cylindrical felt or grinding nylon wheel installed on the drilling machine and kerosene mixed with polishing paste. It is mainly used for decorative processing of round signs and small decorative dial.
Thread thread 2. Use a small motor equipped with circular felt on the shaft to fix it on the table top at an angle of 60 degrees to the edge of the table, and make a carriage equipped with a fixed aluminum plate for pressing tea. Stick a polyester film with a straight edge on the carriage to limit the thread race. Using the rotation of felt and the straight-line movement of carriage, the thread lines with the same width are scratched on the surface of aluminum plate. Of course, wire drawing before electroplating. Nowadays, the general appearance of aluminum alloy products is not plating, but various colors produced by oxidation. Anodizing has been heard that for aluminum, it is mainly to strengthen the surface hardness (a layer of ceramics) and enhance the anti friction performance. Bronzing is also a kind of heat transfer printing. Die casting aluminum parts are a layer of paint which can be painted with a protective film to prevent oxidation after wire drawing treatment. At the same time, it can make the combination of printing material and substrate more firm. Sandblasting is usually carried out in a special sandblasting machine. According to the requirements of the thickness of sand surface, select the appropriate mesh of quartz sand and spray it into the appropriate sand surface. Even and moderate sand blasting can basically overcome the rare defects of aluminum surface. Nowadays, the general appearance of aluminum alloy products is not plating, but various colors produced by oxidation.
