Description

Technical Field

[0001] The utility model relates to the technical field of rubber preparation, in particular to a natural rubber preparation device with low Mooney viscosity and constant viscosity. Background Art

[0002] Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is made by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is made by polymerization of various monomers. Rubber products are widely used in industry and life.
