Use aluminum rivets according to the size of sand holes and tighten them as tightly as possible. The thickness depends on the size of the sand hole. Put some white cement or slaked lime mud around it, cut it into small pieces and rivet it at the sand hole. Or you can buy an aluminum band, just like a band-aid. Just tear off the paper below and paste it directly.

1, aluminum pot characteristics:

Aluminum pot has the advantages of light weight, durability, fast heating, uniform heat conduction and no rust.

It is understood that aluminum products mainly include refined aluminum (soft aluminum) products and cast aluminum (hard aluminum) products, which are made of aluminum and aluminum alloys. Surface colors can be divided into white, light yellow and other colors. White aluminum products are divided into casting and stamping.

After turning and mechanical polishing, the surface of cast aluminum products is white, but the metal structure is loose and there are some casting defects.

Stamped aluminum products with washed white, frosted and mechanically polished surfaces have a natural oxide film with a thickness of only 0.0 1-0. 15 micron, which is thin and uneven and easy to be scratched or worn by machinery.

Yellow aluminum product is a stamping product. After anodic oxidation, a yellowish artificial oxide film is formed on its surface. In general, the thickness of oxide film is 5-20μm, which is uniform and compact. Under the action of strong alkali, 100 second will not damage the film.

Therefore, light yellow aluminum products are the best, beautiful, easy to remove dirt, and have strong corrosion resistance and wear resistance. Koreans often use Huang aluminum pot to cook noodles.

In daily life, many people like to polish the bottom of aluminum pot pot with steel balls. Experts said that although the stains on the pot were wiped off, the protective oxide film on the surface of the aluminum cooker was also wiped off. Therefore, when using aluminum cookers such as aluminum pot and aluminum pot, it is unnecessary to wipe off the yellowish rust on the surface.

2. aluminum pot's choice:

When selecting an aluminum pot, you should pay attention to the straightness and roundness of the pot body, and the bottom, lid and inside and outside of the pot are bright, without darkness or black spots or cracks. At the same time, check whether the structure of rivets, rings and other parts is firm and whether there are pits and sand holes.
