Q:With aluminum foil wrapped 0.1mol metal sodium in water by needle konza a plurality of small holes, after complete reaction, the volume of gas released (standard) (for)A. cannot determine that B.1.12L C. is greater than 1.12L and D. is less than 1.12L

0.1molNa fully reacts to generate V (H 2), =2n (Na),.V, m, =2 * 0.1mol * 22.4L/mol=4.48L > 1.12L,So choose C.

Q:Car sunshade and black aluminum foil which is good, and the aluminum foil is white or cartoon, mainly considering the shading effect?

In the less hot season, colour patterns can be placed out of the room. If the weather is very hot, the foil can be turned out to ensure the reflection of sunlight. In the purchase before the sun block, it is best to choose to take a sucker, the material should be more hard texture. "Light plate" or "too cheap" front sun block is not enough itself, it is easy to fall, so do not seek cheap. In general, there are brands of front sun block, packaging materials used better, there are special placement of suction cups, sucker is not easily squeezed. Worse brands, ten to one, a sucker is squeezed, and the remedy is to put it in boiling water for a while.

Q:Is the self sealing bag made of pure aluminium foil or kraft paper with good sealing property?

Now the standard of living has improved, basically the pure aluminum bag. This will improve the product's shelf life, preservation time is longer, more conducive to product sales.

Q:Can I use the foil instead of the baking paper?

Depends on what to bake, baking paper is usually oil paper, there is anti sticking role

Q:Some drugs are packed on aluminum foil. What's the use of an empty plastic cover?

Drugs are generally more fragile, the outer PET packaging is to isolate the first transparent bulge effective bacteria in the air of dust and moisture, prevent the corrosion of infection drugs, the second physical damage effects in the process of drug transport.

Q:Can I use aluminum foil in the microwave oven?

To make food around the heating evenly, but also to prevent loss of nutrition! I usually do when the beer fish is often used! Aluminum foil can be divided into: high temperature cooking aluminum foil, low temperature aluminum foil, etc.

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:How to calculate the aluminum foil material?How can we calculate the number of meters with weight, length and thickness?

The weight depends on the length, width, density, thickness of the foil. If there is a composite film, the density of the plastic film and the density of the glue will also need to be known

Q:Without the backing of aluminum foil and aluminum foil backing is what is the difference between what is their characteristics?

My factory main operation is aluminum foil roughing mill in 20 years ago, a machine about one million, more than 170 kW, zhenshuang!!!

Q:Which bags are better, such as shield bag, aluminium bag and aluminum foil bag?

Moisture resistant, but because it is not pure aluminum, non puncture; aluminum foil bags the best performance, anti-static, moisture-proof, puncture resistance. If you can help, but also hope to adopt
