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:How to distinguish between PET gold card paper and foil gold paper peritoneum what is the difference?.

2.PET gold paper and aluminium foil gold paper are different in appearance:Know that the manufacturing process is more convenient appearance,.PET film is very bright, in the light of the left and right sloshing, strong reflection. Aluminum foil has a metallic luster, but there is printing layer, poor reflection

Q:Pure aluminum foil, can withstand the maximum temperature?

More than four layers of structure, with good water separation, oxygen separation function. Is not restricted, can bag quantity body is custom-built with different specifications, style, can be made into bag, solid bag, organ bags and other styles. Products are subject to GB and ASTM standards, products comply with environmental requirements (can provide third party inspection report), products comply with the European Union and North America on the packaging materials the most stringent environmental standards.

Q:Can foil be used to shield electromagnetic interference? Please, great God!

There is a certain effect, because it is a metal layer, of course, your package method also has a certain relationship

Q:The aluminium foil is melted and glued to the electric ceramic stove. How can I get rid of it? A safe way of not hurting the stove

Reheated and thawed again.If the area of the foil is slightly larger, you may consider dropping the cold water at the high temperature after heating. But do not control the amount of water dripping. Be careful not to spill the water onto the ceramic panel to damage the panel.

Q:Why aluminum foil used in food packing bags?A, good thermal conductivity, B, good ductility, C and strong corrosion resistance

So most of the soft tins we see are made of aluminum foil

Q:Considerations for hand held aluminium foil sealing machine?

6. This machine uses single phase three wire power line. In order to make the operator safe, make sure to use the single-phase three wire outlet. The ground must be dry in order to keep the insulation.7, the normal input voltage, such as the input power supply voltage is less than 160V, should stop working until the voltage is normal after work.8. The material of the induction aluminum foil must be consistent with the material of the sealed container.9, before the power supply, the induction head must be inserted into the induction air socket, and the nut is locked. Each machine is equipped with a random induction head, and the machine and induction head can not be changed freely.10 、 the machine is equipped with a safety tube of 5A, and no more than 5A safety pipes.11, the machine in use should maintain a good ventilation environment, can not block the ventilation of the chassis.

Q:Which packing material is better, such as shielding bags, aluminum bags and aluminum foil bags?

Of course, the performance is also higher price, better shielding bag can do electrostatic shielding, dust-proof effect, with a certain transmittance; aluminized bag can shade, but also moisture-proof, but because it is not pure aluminum, not puncture

Q:Can screen printing be made on aluminum foil? What are the requirements for various specifications such as process and printing ink and printing thickness?

Can use: polyvinyl butyral (PVB) as binder, solvent dyes (Solvent Dyes) colorant ink.Organic solvents can be used: acetone (small amount) / ethanol / propylene glycol monomethyl ether / two propylene glycol two methyl ether. Safety and environmental protection.

Q:What are the areas in which aluminum foil is applied?

International and domestic production and application of inorganic polymer flocculant have scale, theoretical research has also been further developed. The main raw materials are bauxite, aluminium hydroxide, waste molecular sieve catalyst and so on. The main preparation methods are wet method, electrolysis method and so on. Some scholars believe that the aluminum foil has the advantages of high recovery and reuse of economic value. He experimentally studied the optimum conditions for the preparation of polyaluminium chloride by using waste aluminum foil and the applicable range of the purified water
