Waterproof Aluminum Window Profiles 6m Length For Construction

South Africa Aluminum Window Frame Profiles Frame Casement Connector Brown Aluminium Extrusion

Features of Aluminum Extrusion:

Corrosion resistance
The density of aluminum profile is only 2.7g/cm3, about 1 / 3 of that of steel, copper or brass (7.83g/cm3 and 8.93g/cm3 respectively). Aluminum shows excellent corrosion resistance under most environmental conditions, including air, water (or brine), petrochemical and many chemical systems.

conductivity
Aluminum profile is often selected because of its excellent conductivity. On the basis of equal weight, the conductivity of aluminum is nearly 1 / 2 of that of copper.

Thermal conductivity
The thermal conductivity of aluminum alloy is about 50-60% of that of copper, which is beneficial to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, as well as automobile cylinder heads and radiators.

Non ferromagnetism
Aluminum profile is non ferromagnetic, which is an important characteristic for electrical industry and electronic industry. Aluminum profiles cannot spontaneously ignite, which is important for applications involving handling or contacting flammable and explosive materials.

Machinability
The machinability of aluminum profile is excellent. In various deformed aluminum alloys and cast aluminum alloys, as well as in various states after the production of these alloys, the machining characteristics change greatly, which requires special machine tools or technologies.

Formability
The variation of allowable deformation is dominated by specific tensile strength, yield strength, ductility and corresponding work hardening rate.

Recyclability
Aluminum has high recyclability, and the characteristics of recycled aluminum are almost the same as that of primary aluminum.

Broken Bridge Aluminum Windows Doors Profiles:

Broken bridge aluminum doors and windows are mainly made of heat-insulating broken bridge aluminum profiles and insulating glass, which have the functions of energy saving, sound insulation, noise prevention, dust prevention, waterproof and so on.
advantage:
1. Good thermal insulation;
2. There is a drainage outlet designed to ensure smooth drainage and good water tightness;
3. The three-way sealing structure separates the water vapor chamber, realizes the balance of water pressure and air pressure, and prevents condensation and frost;
4. Metal material, heat insulation strip, high temperature resistance, non combustion, fire prevention function;
5. Broken bridge aluminum doors and windows do not produce harmful materials in the production process, and the materials can be recycled, which belongs to green building materials;
6. High strength, not easy to deformation and corrosion, almost no maintenance.
Disadvantages:
1. To achieve the thermal insulation performance of broken bridge aluminum doors and windows, PA66 thermal insulation strip is required, but its price is high, so the price of broken bridge aluminum doors and windows is also high.
2. In addition, because PVC spacer is cheaper, some illegal businesses may cut corners, so they need to pay more attention when purchasing.

Aluminum Surfaces:

Anode effect is a special phenomenon in molten salt electrolysis, especially in electrolytic aluminum production. In production, when the anode effect occurs, the voltage of the electrolytic cell rises sharply, reaching 20 ~ 50V, sometimes even higher. Its occurrence has a great impact on the whole electrolysis series, reduces the current efficiency, affects various technical indexes of electrolysis, reduces the output and quality of aluminum, and destroys the stable power supply of the whole electrolysis series. In terms of treatment methods, there are no more than two kinds: extinguish with effect rod (wood rod), or reduce the anode and increase the blanking amount of alumina, so as to extinguish the anode effect. No better treatment has been found.

The anode effect occurs because the oxygen-containing ions in the electrolyte gradually decrease with the progress of the electrolysis process. When it reaches a certain degree, fluorine precipitates and reacts with the anode carbon to form carbon fluoride. When the carbon fluoride decomposes, fine carbon particles are precipitated. These carbon particles are attached to the anode surface to prevent the contact between the electrolyte and the anode, The electrolyte can't wet the anode well, just as water can't wet the oiled surface, so a layer of gas film with poor conductivity is formed between the electrolyte and anode, and the anode overvoltage increases, causing the anode effect. When new alumina is added, oxygen is precipitated on the anode, which reacts with carbon powder to gradually calm the anode surface, reduce the resistance, and the electrolysis process tends to be normal.
