1.Structure of D.C AA3105 Aluminum Coils used as Building Material Description

D.C AA3105 Aluminum Coils used as Building Material widly used in decoration field. For the painting, it depends on the using evironment.  If you use in the open air, we recommend the PVDF coated aluminium coils. This kind of painting can last 15-20 years.  If you use in the room, we recommend PE coated aluminium coils. The price is much more competitive.

Direct Continuous Aluminium Foil Stock in Coil is one semi-finished aluminium material. This strip can be rolled down to aluminium foil.The final thickess can be 5-20 microns.  Aluminium foil is soft, ductile and with a silver-white luster which can be widely used in a large scare of fields.

Q:How does Aluminium and Oxygen bond?
Aluminum's outer shell is 3, not 13. 13 is the total number of electrons it has. Looking a the periodic table, Oxygen's usual valance state is -2 as an ion. Aluminum's valance state is always +3. This means that oxygen gains 2 electrons to get a charge of -2 and aluminum lose 3 electrons to get a charge of +3. As for electron configuration, aluminum has 13 electrons in total. 2 e- is in the 1st sublevel. 8 e- is in the 2nd sublevel. That leaves 3 e- left but 3 is not a stable number so aluminum wants to lose those 3 e- to become stable. Oxygen has 8 electrons. 2 e- is in 1st. 6 e- is in 2nd. 6 is not a stable number so oxygen wants to gain 2 more e- to become a full set of 8. Aluminum want to lose 3, Oxygen want to gain 2. We need to balance those. 3 x 2 = 6 2 x 3 = 6 Because Aluminum's usual state is +3, we can have 2 Aluminum atoms bonding. If both lose 3 e-, they both have stable outer shell of 8 (2nd sublevel) and lose 6 e- in total. Oxygen's usual state is -2, but there are 6 e- to gain to oxygen can have 3 atoms bonding. If all 3 atoms receive 2 e- in each, then that's 6 and they're all stable, also at 8 e-. So in order to turn them into happy atom, we need 2 Aluminum and 3 Oxygen to bond together. So the chemical formula is Al2O3 (Aluminum Oxide) *** I'm not very good at explaining, I did the best I can. As for the drawing, I can't do that on the computer. It would have been a whole lot easier if I can though.
Q:When connecting aluminum service conductors to a breaker panel, do I need to use antioxidant?
No you do not have to use any type compound on it.
Q:aluminum welding advise?
- its easy to put a spool of Al wire in a mig welder, but that isn't the issue. as mentioned previously, the Al wire is very soft and may present problems feeding through the long feed tube. hence the design of the spool gun ... tube length = none ... no
Q:Physics--Expansion of Aluminum?
The linear expansivity of aluminum is 23 x10^-6 /K. Bulk expansivity is 3 x 23 x10^-6 / k For 130 [cm^3] the temperature required is 130 [cm] ^3/ 3 x 23 x10^-6 = 0.00013/[3 x 23 x10^-6] = 1.88 K ========================= If each side of the cube of side 1m expands by e, then its new volume = [1+e]^3 = 1 + 3e + 3e^2 +e^3. Neglecting high powers of e as negligible, the increase in volume is 3e. But e = 23 x10^-6 x rise in temperature 3e = 3*23 x10^-6 x rise in temperature. Given 3e = 0.00013 0.00013= 3*23 x10^-6 x rise in temperature Rise in temperature = 0.00013 / 3*23 x10^-6 = 1.88 K
Q:Aluminum coil area, with aluminum sheet area, how is not the same?
Direct measurement length and width calculation area of aluminium plate;The aluminum coil can measure the volume of the aluminum coil and then calculate the area by dividing the thickness. You can also measure the mean diameter, calculate the perimeter, multiply the number of laps, the width, and calculate the area.
Q:cleaning aluminium utensils.....how?
To clean discolored aluminum you can also heat 2 teaspoons cream of tarter per quart of water. It would be best to let the cooker soak in the mixture, but that might be difficult depending on the size of your cooker. Lemon juice or lime juice should also help because they have citric acid. You could cut a lemon in half and rub the halves on the cooker, then try scrubbing with something that has some texture to it (rough sponge or steel wool). The try the vinegar or cream of tarter mixture again. Whatever you use, don't try bleach as it is highly alkaline and dissolves aluminum. This leaves copper deposits can make it turn black.
Q:How do I deal with too much aluminum powder when the aluminum strips are divided?
At present, dust removal system distribution bag filter and water dust collector two kinds.
Q:what are the safety precautions in handling Aluminum?
Aluminum as a solid is very safe; although non-nutritious (your body does not require it), its accumulation in tissues is apparently not directly harmful. Individuals who work years of their lives in handling aluminum have no higher incidence of Alzheimer's disease than those that do not. As a powder- particularly very fine powders- aluminum is extremely hazardous with respect to its combustibility, and is used in fireworks (sparklers, for example). When it burns, it is extremely hot, and extinguishing it should not be attempted without training and the correct tools- usually salt or Purple K extinguishing agent. However, it burns so quickly that it will usually be out before attempts can be made.
Q:Aluminum roll width 750mm, single layer thickness 6.5mm, diameter 400mm., how to calculate the weight of the aluminum roll?
You can use the outside diameter, the inner diameter and the width to get the volume. You know the density and volume, and then you can find the weight naturally
Q:What is the concentration of Aluminum in the Universe?
Interesting, the aluminum must flow? Aluminum is not as common as other elements. It is not readily produced in the cores of stars through the alpha-capture process (which produces things like carbon, oxygen, neon, magnesium, silicon, etc.). This means it is only produced via supernova explosions. The table in Wikipedia (see link below) will give you an idea of the relative abundance to other elements. (Notice that magnesium and silicon, which are before and after aluminum, are nearly 100 times more abundant). As a fellow, Sci-Fi enthusiast, I'd remind you to make you're story believable. If you decide that your universe won't have supernovae, remember that would mean there would be no iron, gold, uranium, etc. My answer has been long enough, but I'm sure you have an idea why aluminum is so abundant on the Earth's crust so I'll stop here.
