Q:aluminum foil?
The shiny side is slightly better reflector of heat. Face that side of the foil in the appropriate direction. To keep things cold, put the shiny side on the outside -- that will reflect incoming heat. To keep things warm, face the shiny side inward toward the hot food -- to reflect the heat that is trying to escape back into the food. Note that people often bake potatoes with the shiny side out -- that is because it makes for a better (prettier) presentation. In reality, baking them that way reflects the incoming heat on the outside, slightly slowing the cooking process. Of course, in reality, which side of the foil faces where makes little difference. It does make for lively conversation, though.
Q:How many atoms thick is aluminum foil?
Good quality standard aluminum foil such as Reynolds brand is 0.007 inches thick. If aluminum atoms are indeed 143 picometers in radius then the foil would be 2,486,713 atoms thick. Of course, the thickness is not controlled to a tolerance of one atom. (Cheaper brands are about 0.0060 to 0.0065 inches thick.) The ionic radius of aluminum is commonly accepted to be 72 pm, and as of 2008 a covalent radius of 121 pm. . .
Q:which kind of aluminum sheet could be bended after being etched?
general etching materials include stainless steel and copper.
Q:Computer cooling aluminum plate, what specific materials used? 30
Copper heat conductivity is good, but the price is more expensive, difficult to process, the weight is too large (a lot of pure copper radiator is beyond the limit of CPU), the heat capacity is small, and easily oxidized. The pure aluminum is too soft, can not directly use, are the use of aluminum alloy to supply enough hardness, aluminum alloy is the advantage of low prices, light weight, but the heat conductivity is much worse than copper. Some of the radiator embedded in a copper plate in each in his element, Aluminum Alloy radiator base.
Q:Does anyone know why Mercury -(Thimerosal) is used in Flu Vaccinations and where Mercuryisnot used Aluminium ?
Toxicity is about dose. The dose of mercury in the flu vaccine is minute and cannot possibly contribute to mercury poisoning. In any case, Thimerosal converts to ethylmercury in the body which is quickly broken down and excreted - unlike methylmercury which is the mercury you are thinking about. A tuna fish sandwich will give you more mercury than any vaccine. Thimerosal is a preservative basically, which is why it is added to the multi-dose vial. If you are that paranoid about it, ask for the single dose vial to be used.
Q:Aluminum plate thickness 3 mm, what is the allowable error in the national standard thickness?
Length: + 1mmWidth: + 0.5mmThickness: + 0.02mm, that is, 2 filaments
Q:What kind of material is 2A12 aluminum sheet?
Corrosion resistance is poor, but it can be effectively protected by pure aluminum coating. It is easy to crack when welding, but it can be welded or riveted by special process. Widely used in aircraft structures, rivets, truck hubs, propeller components, and many other structures.
Q:welding aluminum without gas.?
Mig Welding Aluminum Without Gas
Q:recycling aluminum?
To electrolyse aluminium oxide, it has to be molten. However, the melting point of Al2O3 is extremely high ( 1000°C), and that would make the electrolysis very inefficient. However, Al2O3 dissolves in cryolite at much lower temperatures (lower than 900°C), which makes it a much more viable process.
Q:Aluminum foil a pure element?
Aluminum metal (symbol Al, atomic # 13) is an element and therefore a pure substance. That said, if something is made out of aluminum (like aluminum foil) it is rarely pure aluminum and is typically an alloy composed of mostly aluminum with other metals. Alloys are used to improve the properties of the pure substance in various ways depending on the desired use.
