Rust on casters is a common phenomenon.
The same is caster products, some are easy to rust, some are difficult to rust. Caster products placed in a damp place are easy to rust, but caster products placed in a dry place are not easy to rust; caster products exposed in the air are easy to rust, but painted caster products are not easy to rust. Rusty.
Why does this phenomenon occur? What are the factors related to caster rust?
Through experiments, we found that: water and oxygen are the reasons that make the casters easy to rust. Water alone will not make the casters rust. Only when the oxygen in the air is dissolved in the water, the chemical reaction between the oxygen and the casters in a watery environment will produce something called oxidation casters, which is caster rust. . Caster rust is a brownish-red substance, it is not as hard as casters, and it is easy to fall off. After a caster is completely rusted, the volume can be increased by 8 times. If the caster rust is not removed, this spongy caster rust is particularly easy to absorb water, and the caster will rust faster.
Knowing the secret of caster rust, we can effectively prevent the occurrence of caster rust. Casters in damp places are more prone to rust than casters in dry places, because casters in wet places are more prone to contact with water than casters in dry places. Painted caster products are not easy to rust because the paint plays a role in isolating air and water. If you want to reduce the rust of casters, you can start from the conclusion of the experiment and cut off one of the conditions of rust arbitrarily. If it is painted with paint, it will cut off the contact between the caster and the air. When some caster products, such as kitchen knives, are used up and placed in a dry place, the contact between the caster and water can be cut off, thereby preventing the caster product from rusting.
