Key materials for antistatic casters:
1. Polyester. Also known as acetate fiber, commonly known as PA. The use of polyester makes universal ball casters have a relatively versatile production material. The characteristics of polyester itself are excellent structural mechanical properties, high toughness, high temperature resistance and corrosion resistance, and the surface of the material itself is lubricated and the friction resistance is very low. Polyester can be regarded as one of the materials with high utilization rate in the production of universal ball casters. Universal ball casters made of polyester can also be used in most industries.
2. Polyurethane material. Also known as polyurethane, it is a material made by the addition of organic cyanate and dimethyl. The material characteristics of polyurethane are similar to those of vulcanized rubber and polyester, and have better properties than various materials, such as high vibration absorption and slow rebound, anti-static and other properties. At the same time, polyurethane materials also have high wear resistance. Universal ball casters made of polyurethane materials are widely used in hotels, decoration materials, mineral resources, machinery, transportation and other industries.
3. Vulcanized rubber. Rubber is a material made of natural latex. It has the characteristics of reverse deformation, strong ductility, insulation, water resistance, etc. Universal ball casters made of rubber can maintain stable contact with the road surface, and have excellent anti-skid properties.
What are the factors related to the rust of anti-static casters:
Through experiments, caster manufacturers have found that air and O2 are the reasons why casters are prone to rust. Water storage alone will not cause casters to rust. Only when oxygen in the air dissolves in water, oxygen will react chemically with casters in a water environment to form a substance called air-oxidized casters, which is caster rust. Caster rust is a reddish-brown substance. It is not as hard as casters and is easy to fall off. After a caster is completely rusted, its volume can be increased by 8 times. If the caster rust is not removed, this honeycomb 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 humid areas are more likely to rust than those in dry areas because casters in humid areas are more likely to come into contact with water than those in dry areas. Painted casters are less likely to rust because the paint has the function of blocking air and water. If you want to reduce the rust of casters, you can consider the test results and randomly cut off one of the rusting conditions. If you paint it, the contact between the caster and the air will be cut off. If you wipe some caster products such as fruit knives after use and put them in a dry area, you can cut off the contact between the caster and water, thereby preventing the caster products from rusting.
