Suzhou Hongnuan Electronics to introduce: the characteristics and types of brushed aluminum plate

Introduction to brushed aluminum sheet

Drawing treatment is to be done after stamping, drawing is usually drawn after oxidation to ensure the anti-corrosion performance after drawing, the use of 3003 rust-proof aluminum plate drawing, according to the decoration needs, made into straight lines, chaos, thread, corrugated and spiral lines and so on.

Straight drawing:

It refers to the straight lines processed by mechanical friction on the surface of the aluminum plate. It has the dual function of brushing and removing scratches on the surface of aluminum plate and decorating the surface of aluminum plate. There are two kinds of straight drawing: continuous and discontinuous. Continuous silk can be obtained by using a clean cloth or stainless steel brush through continuous horizontal linear friction on the surface of the aluminum plate (such as manual grinding under the condition of the current device or by clamping the steel wire brush with a planer in the aluminum plate). Change the diameter of stainless steel brush wire, can obtain different thickness of grain. Intermittent silk is usually processed in a brush or wipe machine. Production principle: Two sets of differential wheels rotating in the same direction are adopted. The upper group is a rapidly rotating grinding roller, and the lower group is a slow rotating rubber roller. When aluminum or aluminum alloy plates pass through the two sets of rollers, they are brushed with fine and intermittent straight lines.

Mess drawing:

Under the copper wire brush running at high speed, the aluminum plate moves around and around the friction to obtain a kind of irregular, no obvious lines of matte silk. This kind of processing, aluminum or aluminum alloy plate surface requirements are higher.

Corrugated wire drawing:

Corrugation is generally made in the brush or wipe machine. By using the axial motion of the grinding roller, the surface of the aluminum or aluminum alloy plate is rubbed to get the wavy pattern.

Curl drawing:

Spiral grain, also known as optical rotation, is a kind of silk grain obtained by rotating polishing on the surface of aluminum or aluminum alloy plate by using cylindrical felt or stone nylon wheel mounted on a drilling machine and mixing kerosene with polishing ointment. It is used for circular signs and small decorative dial decorative processing.

Thread drawing:

Thread is to use a small motor equipped with circular felt on the shaft, it is fixed on the table, and the table edge at an Angle of about 60 degrees, in addition to make a fixed aluminum plate press tea, on the drag plate attached a straight polyester film to limit the thread race. By using the rotation of the felt and the straight line movement of the drag plate, the thread lines of the same width are created on the surface of the aluminum plate.

Sandblasting is done to obtain a surface with a film light decoration or a slightly reflective surface to meet special design needs such as a soft gloss. Uniform and moderate sandblasting treatment can basically overcome the common defects on the surface of aluminum.

For the appearance of parts, whether with wire drawing or sandblasting, usually need to do surface oxidation treatment. As for the choice of what kind of processing technology, should be related to the modeling to consider a problem, the surface texture of the two kinds of technology can be obtained or there are differences.

In addition, there is a process close to sandblasting, but it is carried out by a chemical corrosion method, commonly known as chemical sand rotten treatment or chemical sand surface corrosion, especially for aluminum surface treatment, the uniformity of the sand surface is far better than sandblasting treatment, chemical sand surface corrosion is divided into acid corrosion and alkaline corrosion. Different surface color and sand thickness can be obtained by different corrosion solvents and sand surface agents.
