Metal is a substance that has the properties of luster, high ductility, easy electrical and thermal conductivity, etc. Most of the metal elements on earth exist in the natural world in a combined state. This is because most metals are chemically active and very few metals, such as gold and silver, exist in a free state. Metals are widely found in nature, are very commonly used in life, and are a very important and most used class of materials in modern industries.
Rusting is a common chemical reaction on the surface of metal, and can occur when iron is left for a long time. Iron is easily rusted and is also very much related to external conditions besides being active due to its chemical properties. Moisture is one of substances that make iron easily rusted. However, iron does not rust only with water, and only when oxygen in the air is dissolved in water, the oxygen reacts with iron in an environment with water to form iron oxide, which is rust. Iron rust is a brownish red substance which is not as hard as iron and is easy to fall off, and after a piece of iron is completely rusted, the volume can be expanded by 8 times. If the rust is not removed, the sponge-like rust is particularly prone to absorb moisture and the iron will rust faster. Iron may weigh more when rusted, about 3 to 5 times the original weight.
The metal rusting treatment method comprises the following steps:
1. physical method, using steel wire ball to brush or using sand paper to polish until brightness, in short, removing rust as clean as possible;
