Q:Why does aluminum react this way?
Aluminum reacts like the elements in its group, the elements that are above and below it, such as Boron and Gallium. This is due to its valance electrons which you can find out through its electron configuration. It has 3 valance electrons, while the other elements you mentioned follow different rules due to their valance electrons. Ultimately, aluminum does not act like those because it is not in that family/group.
Q:Why use aluminum foil packaging of cigarettes?
Foreign manufacturers in the development of new cigarettes, Backing aspect is a lot of work, BAT also use vacuum aluminum as its brand-name cigarette packet lined packaging material, according to statistics, at present, 70% of British cigarettes, 50 % of German cigarettes are cigarettes made with aluminum inner liner. Armenian producers in order to increase protection of the product, the use of duplex printing and foil baking sheet liner, an Indonesian company has introduce a metallised material to replace the original multi-layer composite aluminum foil paper, aluminum foil, its thickness is only 0.04 m.
Q:How to make aluminum foil paper?
A method to manufacture aluminum foil paper with forgery-proof watermark is made from paper pulp fiber. The production steps are as follows: Crash the pulp material with hydrapulper and beat with beater with beating degree of 20-70°SR and wet weight ≥0.5g; Add additives to the pulp: Filler 10-40%, sizing agent 1-8%, preservative 350ml/ton; Beating degree of 20-70°SR and wet weight ≥0.5g; Press the watermark net with die sinking, use watermark net at the vat of paper machine, reproduce the pulp into paper sheet with paper machine after being diluted, roll the sheet with calendar, slit the sheet into corresponding specification with slitter and then get the aluminum foil backing paper with forgery-proof watermark. The watermark of this invention is distributed uniformly, clearly visible as well as obviously rough and uneven in surface by touching, which has significant counterfeit effect, so it can be used to package the cigarette. Sovereignty item 1: A method to manufacture aluminum foil paper with forgery-proof watermark is made from paper pulp fiber. The production steps are as follows: a. Beating: Crash the pulp material with hydrapulper and beat with beater with beating degree of 20-70°SR and wet weight ≥0.5g; b. Composite pulp tank: Add additives to the pulp: Filler 10-40%, sizing agent 1-8%, preservative 350ml/ton; beating degree of 20-70°SR and wet weight ≥0.5g; c. Press the watermark net with die sinking, use watermark net at the vat of paper machine; d. Reproduce the pulp into paper sheet with paper machine after being diluted, roll the sheet with calendar, slit the sheet into corresponding specification with slitter and then get the aluminum foil backing paper with forgery-proof watermark; e. Composite aluminum foil with watermark aluminum foil backing paper to make aluminum foil paper with forgery-proof watermark.
Q:Is the aluminum foil bellows insulated or thermally conductive?
It depends on the intention of using the pipe! Aluminum foil has good thermal conductivity! But he can reflect the heat of radiation! His bellows also have a few points, one is corrugated tubes, heat exchange area much larger than the light pipe, and there is bellows flexibility is better! It is not easy to break in thermal expansion and cold contraction! So this kind of pipe is widely used in the field of heat conduction!
Q:Does working in the aluminum foil companies harm the health?
I am working in the same company with her and I am a maintenance worker in aluminum foil workshop.To be honest, it is the cleanest workshop in the whole factory. Only little kerosene can be smelt. What's more, her main job is foreigh trade, nearly outside the workshop.
Q:Is a aluminum case non detectable?
Well, lets brain this out together. We know that aluminum is metal, so it will set off a metal detector. Now, if a guard at that metal detector gets lazy and fails to open the case, well then yes the guns go undetected. But if the guard is doing his job, then he opens the case and the bad guys go to jail. Now lets pretend that it went through an X-Ray machine. The X-rays go right through aluminum and the guard would see the contents of the case. Only lead can stop X-Rays, and if that aluminum case had a lead lining the guard would again demand that the case be opened. Honestly, brain work and common sense are on the decline.
Q:Screen line of aluminium foil layer 20
One layer of aluminum foil, shielding better.
Q:How to wash away the oil of aluminum foil products after being pressed?
I suggest that you can use the volatile punching oil since it won't be rudimental.
Q:What size copper wire to get equivalent resistance as aluminum?
aluminum wire with diameter 3.26mm Resistance of a wire R = ρL/A ρ is resistivity of the material L is length in meters A is cross-sectional area in m² A = πr² resistivity Cu 17.2 (nΩ-m) resistivity Al 28.2 (nΩ-m) 1 = Al 2 = Cu ρ1L1/A1 = ρ2L2/A2 lengths are the same ρ1/A1 = ρ2/A2 ρ1/ρ2 = A1/A2 28.2/17.2 = π(1.68)²/πr² 28.2/17.2 = (1.68)²/r² r² = (1.68)²17.2/28.2 r² = 1.72 r = 1.31 d = 2.62 mm .
Q:Chemistry, formula of Aluminium oxide, question?
Aluminium oxide has the formula Al2O3 because in an ionic compound, in order to be neutral, the charges of each ion must be counteracted by the opposite charge. Al forms a 3+ ion and O forms a 2- ion. To make the charges match each other, with the smallest number of atoms possible, I look for the smallest common multiple of 2 and 3, which is 6. Therefore to cancel each other out, the Als must have a charge of 6+ and the Os must have have -6 charge. To make the charge of the Al 6+, I added a an Al atom to the formula = Al2 Then to make the charge of the O 6-, I added two Os, giving 3 O atoms. Hence my formula = Al2O3
