How does the caster plant prevent the caster bracket from rusting!

Update:2017-03-15

Rusty casters are a common phenomenon. The same is the caster products, some are easy to rust, and some are difficult to rust. Caster products placed in damp places are prone to rust, and caster products placed in dry places are not easily rusted; caster products exposed in the air are prone to rust, and painted caster products are not easy. Rusty.
 
Caster rust is a brown-red material that is not as hard as a caster and can easily fall off. When a caster is completely rusted, the volume can be increased by 8 times. If the caster rust is not removed, the spongy caster rust is particularly easy to absorb moisture, and the caster will rust faster.
 
Water and oxygen are the reasons why the casters are prone to rust. Light and water will not rust the casters. Only when the oxygen in the air dissolves in the water, the chemical reaction between oxygen and the casters in the water environment will produce something called oxidized casters. This is the caster rust. .
 
Knowing the secret of the rust of the casters, we can effectively prevent the generation of caster rust. Casters in wet locations are more susceptible to rust than casters in dry locations because casters in wet locations are more susceptible to water contact than casters in dry locations. However, painted caster products do not rust easily because the paint acts to block air and water.
 
If you want to reduce the rust of the casters, you can arbitrarily cut off one of the conditions of rust. Applying paint on it cuts off the contact between the casters and the air. When some caster products such as kitchen knives are used up and dried and placed in a dry place, the contact between the casters and the water can be cut off to prevent the casters from rusting.
