Aluminum Extrusion
Method of Polishing Aluminum:
1. Mechanical Polishing:
The main purpose of this paper is to use polishing wheel coated
with polishing wax to process the surface of aluminum alloy shell,
which can reduce the roughness of the surface of aluminum alloy
shell, make the surface smooth, obtain bright or mirror effect, and
effectively repair the scratch and scratch of the surface of
aluminum alloy shell.
2. Electropolishing:
Electrolytic polishing is used to immerse the electrolytic bath
with chemical reaction as anode and insoluble metal as cathode. The
anodized alumina is dissolved by DC, and the alumina disappears
from the aluminum profile shell to restore luster.
3. Chemical Polishing:
Chemical polishing can be used as the pretreatment process of
protective decorative plating, or as the pretreatment process of
chemical film forming such as phosphating hair blue. If the
solution of antirust passivation agent is immersed before painting,
the aluminum oxide on the surface of the aluminum profile shell can
be eliminated.
4. Ultrasonic Polishing:
Ultrasonic polishing is a kind of processing method which uses tool
section as ultrasonic vibration and polishing brittle hard material
by abrasive suspension. The workpiece is put into the abrasive
suspension and put in the ultrasonic field together. Depending on
the vibration of ultrasonic, the abrasive can be ground and
polished on the surface of the workpiece.
5. Fluid Polishing
Fluid polishing technology needs to rely on the flowing liquid and
the abrasive particles carried by it to wash the surface of the
workpiece to achieve the purpose of polishing. Hydrodynamic
grinding is driven by hydraulic pressure. The medium is mainly made
of special compound with good fluidity under low pressure and mixed
with abrasive. Silicon carbide powder can be used as abrasive.

Different Dluminum Surface Treatments:
1. Passivation
An active metal or alloy in which the chemical activity decreases
greatly and becomes the appearance of precious metal state, which
is called passivation. Passivation treatment is a method to make
the metal surface not easy to be oxidized, which can delay the
corrosion rate of metal.
2. Anodizing
Anodizing is a process of plating an oxide film on the surface of
some metals or other metals or alloys by using the principle of
electrolysis. It has the effect of protecting the metal surface
from oxidation and enhancing corrosion. Brush plating is used for
local plating or correction. Barrel plating is used for small
parts, such as fasteners, washers, pins, etc. After electroplating,
aluminum profiles can obtain decoration protection and various
functional outer layers on mechanical finished products, and can
also correct worn and processed workpieces. The plating solution
includes acidic, alkaline and acidic and neutral solutions with
chromium agent. No matter what plating method is selected, it
should be universal to a certain extent with the finished products
to be plated and the plating bath and hanging tools touched by the
plating solution.
3. Spraying
Spraying is used for external protection and decoration of
equipment, which is usually carried out on the basis of oxidation.
The aluminum profiles of aluminum alloy doors and windows should be
pretreated before coating to make the coating firmly connected with
the workpiece. There are usually three methods: (1) phosphating
(phosphate method); (2) Chromization (chromium free); (3) Chemical
oxidation.
4. Sandblasting
The primary effect of sand blasting is surface finishing. Before
coating (painting or plastic spraying), sand blasting can add
surface roughness and make a certain contribution to the progress
of adhesion, but the contribution is limited, which is not as good
as chemical coating pretreatment.
5. Chemical oxidation
The oxide film is thin, about 0.5 ~ 4 microns thick, porous, soft
and has excellent adsorption. It can be used as the bottom layer of
organic coating, but its wear resistance and corrosion resistance
are not as good as anodized film treatment.
Mechanical Polishing:
Electropolishing is commonly used in the decorative processing of
steel, aluminum, copper and other parts, or copper nickel and other
coatings,
Electropolishing can be used to replace heavy mechanical polishing,
especially for its complicated shape and difficult to add by
mechanical method
But electropolishing can not remove the non-metallic inclusions in
the gold, nor can it remove or mask the metal
Surface defects such as scratches and deep pockmarks on the
surface. In multiphase alloys, when one phase is not easy to
dissolve in the anode, it will shadow
The quality of electropolishing. Chemical polishing is the chemical
etching of metal parts under specific conditions. After this
etching
During the process, the metal surface is etched and leveled by
solution to obtain a brighter surface
Chemical polishing can be used in the manufacture of instruments,
aluminum mirrors, and other parts and coatings
Compared with electropolishing, the advantages of chemical
polishing are: no external power supply is needed, and the shape
can be processed more easily
