Are some uses of galvanized barrels really feasible?

Science is everywhere, it is often around you, and you have not discovered it. Let us walk into science and explore its path. If we do not seriously understand science, there may be some dangers in use, such as simple galvanized barrels should also be carefully understood before use.

Many people have questions, what kind of zinc is galvanized in galvanized barrels? White iron barrels are actually galvanized iron barrels. Zinc is a white soft and shiny metal, which is easily soluble in acidic solutions. If acidic foods and beverages are prepared or stored in white iron barrels or other galvanized utensils, zinc dissolves into food in the form of toxic organic acids, and people are at risk of poisoning after eating. Therefore, when using galvanized containers, it must not be used to hold acidic dishes, soups, alcohol, juice, milk and other beverages. There are also two reasons why ammonia water cannot be used to corrode metals: one is that ammonia can form alloying ions with metal ions, and the other is that the atmosphere contains a large amount of oxygen. To explain more specifically, since ammonia can form relatively stable alloying ions with many metal ions, it will reduce the standard potential between metal ions and metal elements, which means that metals are more easily oxidized. In addition, the earth's atmosphere is an oxidizing atmosphere, so metals become more easily oxidized, which is the phenomenon of corrosion. If it is more precise, it is the oxygen in the atmosphere that corrodes metals, and the function of ammonia is to make corrosion easier.

Some people also want to ask galvanized barrels to raise fish, what kind of water can put fry?

If you want to use it for fish farming, you need to pay attention to some details. First of all, fully clean the galvanized barrel to ensure that there are no impurities inside, and use a special disinfectant for disinfection. Then fill it with water, add an appropriate amount of breeding drugs, and fully circulate the water body to achieve stable water quality conditions. Generally speaking, when the water temperature is stable at 18-25 ° C and the pH value is controlled at 6.5-8.0. the content of ammonia nitrogen, nitrite and nitrate is controlled within the range, the water quality is transparent, and the breeding drugs are diluted and transparent, you can consider putting fry. Pay attention to controlling the number of fry to prevent excessive density from causing death. In addition, it is necessary to regularly add an appropriate amount of bait according to different fish species to maintain a good breeding environment in order to successfully cultivate fish.

Sometimes we see galvanized barrels used to transport diesel. Will they rust when used to hold diesel? In fact, it is a commonly used container for storing and transporting diesel. The galvanized layer can effectively prevent the barrel from rusting. However, if the galvanized layer is damaged or worn, it will cause the barrel to rust. In addition, if the diesel contains moisture or other corrosive substances, it will also accelerate the rust of the barrel.

Therefore, in order to ensure the quality of galvanized barrels of diesel, it is necessary to pay attention to choosing good quality galvanized barrels to ensure that the quality and thickness of the galvanized layer meet the standard requirements. When storing and transporting diesel, avoid impact or friction on the barrel body to avoid damage to the galvanized layer. Regularly check the surface of the barrel. If the galvanized layer is found to be damaged or worn, repair or replace it in time. Avoid moisture or other corrosive substances in diesel. This can be achieved by using dry diesel and cleaning the barrel body regularly. Galvanized barrel diesel will not rust under normal circumstances, but attention should be paid to maintenance and maintenance to ensure the integrity of the galvanized layer and the quality of the diesel.

A random little thing contains endless science. As long as we explore and discover, we will know more and more knowledge. Regarding the usage of galvanized barrels, we need to know the principle so that there will be no loss due to operation errors.
