FAQ

Battery why aluminum foil as anode, copper foil as negative electrode?

In addition to stability, it is necessary to consider the conductivity of the material, whether it can be machined thin, as well as mechanical strength, cost and other factors. Finally chose Cu and Al.

What is the specific weight of aluminum foil?

Aluminum foil is a metal aluminum directly rolled into sheets of hot stamping material, the effect of stamping and silver foil stamping similar effects, it is also called the false. Because of its soft texture and good ductility, it has a silvery luster. If the rolled sheet is made of sodium silicate on the offset paper, the foil can be printed. But the aluminum foil itself is easy to oxidize and the color is dull, friction, touch and so on will fade. Therefore, it is not suitable for the long-term preservation of books, covers and other hot stamping.

How to use aseptic packaging aluminum foil bag?

As the name suggests, that is, the elimination of bacteria, extinction. The main cause of spoilage in foods, beverages, and drugs is the reproduction of bacteria in food or beverages. Do not take the necessary measures, whether food, beverage or packaging containers into foil bags' in the production process will have more or less organic microorganisms exist, at any time may suffer the effects of pollution, the plastic packaging bag material or taste, or deterioration, or corruption fermentation. Microorganisms generally include bacteria, fungi, yeasts, and actinomycetes. It is a single celled organism that can be found anywhere in the world. Generally, their growth temperature is between 0-60~C and sensitive to moisture content. Food, drink or drugs, medical equipment and other "aluminum foil bag" processing must ensure that the production of installed sealed products can meet requirements of the sale of disinfection products, and strive to reduce the decline in product quality, such as food and drinks after the flavor, color, nutrient unchanged, and thereafter not bad. For this purpose, physical or chemical methods are used to kill microorganisms in the process of food or beverage processing. For food and beverage, sterilization treatment does not mean that microorganisms do not contain requirements in food and drink, but said the food or beverage containing no harmful to human health may or may breed in general storage conditions and make the food or drink of corruption have life force. All the bags will not exist in the processing of microorganisms in foods or beverages were killed, but can make the bags of food or drink from a living organism development condition, adopt feasible sterilization method, kill harmful microorganisms, ensure food or beverage quality and flavor stability, prolong the storage period.

Why can copper foil and aluminum foil shield electromagnetic signals?

Therefore, they usually back conductive adhesive, otherwise shielding effectiveness is very poor, under normal circumstances, with conductive adhesive copper foil / aluminum foil can reach more than 90dB, with flying conductive adhesive only about 40dB

What kind of food grade aluminum foil does it mean?

The grill is a metal aluminum foil, long-term excessive intake of aluminum, is toxic.

What are the characteristics of aluminium foil waterproof coiled material?

Aluminum foil paper is soft and easy to change, like paper, and it doesn't bounce after deformation. It can be assured that shading will not fall, light, pollution free and cheap. For high grade cigarettes, sweets and other food moistureproof and decorative packaging.

What material is the aluminum foil made of?

And allows the unit to work within the diameter of the wear, so it does not require surface hardness, only requires a higher strength, toughness and heat resistance. The hot rolling roller only adopts the whole normalizing or quenching, and the surface hardness demands HB190~270.

Under what conditions can aluminum foil be oxidized?Under what conditions can aluminum foil be oxidized easily? I mainly want to prevent the oxidation of aluminum foil, how much is it with air humidity, or how much humidity range is not easy to be oxidized?

Aluminum is chemically active and easily oxidized. In air, because of the formation of a dense oxide film after oxidation, it prevents the further oxidation of aluminum. High temperature can destroy the oxide film and accelerate the oxidation reaction.
