Description

Technical Field

[0001] This utility model relates to the field of rubber spraying technology, and in particular to a rubber spraying device. Background Technology

[0002] Rubber is an elastic material widely used in industry and daily life. It has high elasticity, can deform when subjected to external force, and can return to its original shape after the external force is removed. Rubber is usually composed of natural rubber and synthetic rubber. Natural rubber is latex extracted from rubber trees, while synthetic rubber is obtained through chemical synthesis. Common types include styrene-butadiene rubber and chloroprene rubber. Rubber coatings can enhance the corrosion resistance, aging resistance, water resistance, and slip resistance of objects. They are widely used on the surfaces of metals, plastics, and other materials to extend the service life of objects.
