Description

Technical Field

[0001] The utility model relates to the technical field of adhesive production, and particularly relates to a heat exchange system applied to adhesive production. Background Art

[0002] Adhesives are relatively common materials in industrial production and are the general term for various stress materials that connect or bond the same or different materials. There are mainly three types: liquid, paste, and solid. Adhesives are one of the most important auxiliary materials. To improve the effect of adhesives, multiple components need to be added. By virtue of their adhesive properties, two separated materials can be connected together, which is relatively convenient to use and the connection is relatively stable, so they are widely used. During the production process of adhesives, the raw material mixture needs to be heated, so a large amount of heat energy is usually generated during the production of adhesives. However, this heat energy is often directly discharged into the outside world without conversion and utilization, resulting in a waste of energy and being unfavorable for energy conservation and environmental protection.
