Description

Technical Field

[0001] This utility model relates to the field of adhesive technology, specifically to a tube for use in adhesives. Background Technology

[0002] Adhesives are substances that firmly bond two or more parts or materials together. In actual use, two-component adhesives are mixed together to improve adhesion.

[0003] Two-component adhesives are simultaneously injected into a tube with a spiral mixing core, and pressure is applied to extrude them through the tube opening. During this process, thorough mixing is achieved through the spiral mixing core. However, the mixing tube has a limited lifespan, and wear or blockage of the spiral structure of the core will change the fluid cutting efficiency, thus affecting the mixing ratio. In contrast, traditional spiral mixing cores are integrally molded with the tube, and when the core becomes blocked, the entire tube needs to be replaced, increasing the cost of use. To address these issues, we have proposed a new type of tube for adhesives. Utility Model Content
