Casement Window Frame Cnc 6063 Polished Aluminium Profile

Casement Window Frame Machined Cnc Bright Silver Polished Aluminium Building Decoration Profiles

Profile Detail:

Different surface treatment of aluminum profies:

1. Anodic oxidation: porous oxide film can be formed, the hardness of the film can be up to 500hv; the oxide film with porous structure can also absorb lubricant, pigment, etc. to enhance the corrosion resistance and wear resistance of the material surface; it has good insulation effect, and can prevent breakdown voltage greater than 30V / μ m; it has strong high temperature resistance and can withstand 1500 ℃

2. Electrophoretic coating: water is used as dispersing medium and a small amount of cosolvent can reduce the pollution of air and water quality, and will not cause fire hazard; the coating has good swimming permeability and can cover the edge and gap of aluminum profiles

3. Powder spraying: the molecular weight of resin for powder coating is higher than that of solution coating, which makes the surface of aluminum profile have good chemical resistance

4. Chemical polishing is a chemical processing method that uses the selective self dissolution of aluminum and aluminum alloy in acidic or alkaline electrolyte solution to level and polish the surface of the year, so as to reduce the surface roughness and pH. This polishing method has the advantages of simple equipment, no power supply, no limitation of the size of the workpiece, high polishing speed and low processing cost.

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

However, the surface quality of chemical polishing is generally slightly lower than that of electropolishing and solution polishing

It is also difficult to adjust and regenerate. Nitrogen oxide and other harmful gases are often precipitated during polishing

In the process, a thick film with high resistivity is formed on the anode surface, which is on the micro protruding part of the surface

The thickness of the current density is small, and the thickness of the micro concave is large, so the micro distribution of the current density is also uneven,
