Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber heating technology, specifically a heating component for rubber pretreatment. Background Technology
[0002] As a polymer material, rubber has high hardness at room temperature and relatively poor plasticity and ductility. Through heat pretreatment, heat can be transferred to the rubber quickly and evenly, which weakens the intermolecular interaction forces, makes the chain segments easier to extend and flow, and thus significantly improves its plasticity and processing performance.
[0003] When pre-treating rubber compounds by heating, the heating components are usually placed inside the storage tank to ensure that the rubber compounds maintain an appropriate temperature and prevent solidification. During the process of transporting the rubber compounds from the storage tank to the production equipment through the conveying pipeline, a series of measures need to be taken to maintain the temperature of the rubber compounds and prevent them from solidifying, so as to ensure the continuity and stability of the production line. The heating components used in common conveying pipelines are heating wires wrapped around the outer wall of the pipeline. The heating wires heat the rubber compounds flowing in the pipeline to prevent solidification.
[0004] However, when the heating wire is wound around the outer wall of the delivery pipe, although heat can be transferred to the medium inside the pipe through heat conduction, some heat will also dissipate to the outside of the pipe, causing heat loss from the heating wire and thus affecting the heating effect. Therefore, those skilled in the art have provided a heating assembly for pretreatment of adhesive materials to solve the problems mentioned in the background art. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a heating component for pretreatment of adhesive materials, which solves the problem that when the heating wire is wound around the outer wall of the conveying pipe, although heat can be transferred to the medium inside the pipe through heat conduction, some heat will also be dissipated to the outside of the pipe, resulting in heat loss of the heating wire and thus affecting the heating effect.
