Description

Technical Field

[0001] The utility model relates to the technical field of rubber dissolution, in particular to a rubber dissolution device with an expansion buffer structure. Background Art

[0002] Rubber dissolution technology is a process of dissolving rubber materials into liquid or semi-solid forms. This technology is widely used in the fields of rubber processing and recycling, making rubber materials easier to handle and reuse. This article will introduce the principles, applications and development trends of rubber dissolution technology. The principle of rubber dissolution technology is to use solvents to decompose rubber materials into molecules or substances with smaller microstructures. The solvent can be an organic solvent, water or other specific solvents. During the dissolution process, the solvent interacts with the rubber material, causing the rubber molecular chains to break or dissolve. The dissolution device is an indispensable equipment for rubber dissolution.

When used in rubber dissolving, the rubber blocks cut from the rubber cutter are first mixed with a low-temperature solvent in the premixing tank and then intermittently and centrally placed in a higher-temperature dissolving tank. This reduces solvent loss and lowers rubber manufacturing costs.
