Q:Can foil be insulated?Indeed, the foil is reflective of the sun's rays

To be exact, the foil reflects the sun's rays and turns the radiation to other places instead of heat insulation, but it acts as heat insulation. The brighter the foil, the stronger the reflectivity.

Q:When the wire is made, it needs a layer of foil inside, and the outside is insulated. Why is that?

Insulation is done outside to protect or leak electricity.Cable foil is the use of aluminum foil sealing and shielding, single or double coated plastic film, an aluminum foil plastic composite #

Q:Aluminum foil waterproof material, how much does it cost for a square?

The material is different, the price is also different. You first have to figure out what waterproof material can determine the price of this material.

Q:How can I clean the aluminum foil products when they are punched out?

There are many kinds of drawing oils, and there are usually special cleaning agents. You can specifically ask your drawing oil supplier, according to the oil purchase.

Q:The aluminum foil is induced by a magnetic field. Why does it produce the opposite magnetic field?

Because the induced magnetic field and the magnetic field belongs to the series, this series is similar as the battery positive and negative, the induced magnetic field is similar to positive and negative is similar to that induced by magnetic field produces the opposite magnetic field by aluminum foil. Such as magnets attract nails, nails through the magnetic field lines are external magnet (external) magnetic field lines,

Q:Aluminum foil surface, SBS roll multilayer superposition, waterproof effect is good?

Generally speaking, SBS waterproofing membrane superimposed use, will certainly be better than the use of single layer. But the first time with the construction of aluminum thread with a little waste. Because aluminum Bu in coil plays only a reflective insulation function, so if the two house the first time it is not necessary to use the superposition with aluminum Bu, PE film can be second times, and then the aluminum coil Bu

Q:Can foil work at 430 degrees high temperature?

Therefore, it can be inferred that if oxidized, the final result may not be aluminum foil, but also alumina. A touch may be powdery...

Q:The foil can be used in the microwave heating?

The electric field of thick metal can resist the microwave, and the microwave reflected out, so the inner wall of the microwave oven is made of thick metal; if the thick walled metal container in the microwave and metal containers will reflect the microwave so that the food is not heated. But the foil is too thin, so electrical conductivity can cause a catastrophic reaction. The process of conducting a thin metal so rapidly that its temperature rises linearly can cause a fire. At the same time, the tip produced by the heat contraction of the foil causes sparks, which can ignite any combustible material in the microwave oven.

Q:Can the potatoes be heated by foil?

Of course, things wrapped in aluminum foil can not be heated in microwave ovens

Q:Can the potatoes be heated by foil, please?

The potatoes can be wrapped in foil and heated in an oven or other heat source, and the water does not evaporate. It works very well.
