How to get medicinal aluminum foil
All the magic of aluminum foil It can be used to encapsulate drugs and block the erosion of drugs by air moisture; it is also often used to package food. The aluminum foils we use are relatively small in volume and mass. Have you ever wondered how a large piece of aluminum can become a small aluminum foil?
We all know it many exquisite products are processed from rough raw materials. The manufacture of aluminum foil requires the repeated thinning out of a large block of aluminum.
Firstly, we need to begin by melting ingots of 100% pure aluminum in a natural gas furnace. These ingots called pigs are essential in alloy with zinc, titan, and silicon.
It often takes a long time for the raw material aluminum to be refined. Some large processing tanks can process nearly 30 tons of bulk aluminum in 3 hours at a temperature of 750°. The melting point of aluminum is 660°, and the aluminum block will melt into molten aluminum after being heated.
At this time, the aluminum water will be poured into the corresponding aluminum mold to make aluminum foil samples. After the aluminum water lacks continuous heat, it will be cooled and shaped in a few seconds. The shaped samples will be taken to detect the metal composition after impurity removal.
In order to further remove impurities, the refractory tank is used to lead the molten aluminum from the molten aluminum to the slag outlet, and the molten aluminum flows into the movable opening below the slag outlet. After this step, most of the impurities can be removed. The water cooling of the mold will accelerate the solidification of the molten aluminum. At this time, the molten aluminum becomes an aluminum ingot after preliminary impurity removal.
The surface of these aluminum ingots can be polished smoother by the treatment of the surface separation scraper. After that, the aluminum ingot is squeezed by hot rollers, and oil-water coolant is continuously injected to prevent adhesion during the process. After such hot roller squeezing, the thickness of the aluminum ingot will be further thinned.
After multiple extrusions, the aluminum ingot became a thinner aluminum sheet. At this time, the aluminum sheet has become lighter and thinner. In order to prevent the aluminum sheet from breaking during the folding process, the aluminum sheet will be double-passed at this time, and the aluminum sheet will be processed to the thickness required by the customer after the last step of light rolling. Since the edge of the aluminum foil will be damaged or wrinkled, use a blade to cut off the edge of about one centimeter, and finally reach the thickness of the aluminum foil required by the customer.
