Description

Technical Field

[0001] The utility model relates to the technical field of engineering equipment, in particular to a temperature control device for producing master batches containing hydrotalcite-like substances. Background Art

[0002] With the continuous advancement of plastics processing technology, functional plastic masterbatches are increasingly being used in various fields. Masterbatches are concentrated granules made by mixing functional additives, pigments, or fillers with a carrier resin and then undergoing a specific processing step. They are widely used to modify and enhance the performance of plastic products. Hydrotalcite-like masterbatches, in particular, have become important materials for plastic modification due to their excellent thermal stability, UV absorption, and flame retardancy. Temperature control is a crucial factor in the production of hydrotalcite-like masterbatches, impacting product quality. Twin-screw extruders are key equipment in masterbatch production, mixing, plasticizing, and extruding materials through the rotation and squeezing action of the screws. However, uneven material temperature during the extrusion process can lead to fluctuations in product performance and even cause processing equipment failure. Traditional temperature control devices typically rely on simple electrical heating, which struggles to achieve uniform heating and precise control of the material, resulting in low production efficiency and unstable product quality. Therefore, developing an efficient and precise temperature control device is crucial for improving the production efficiency and quality of hydrotalcite-like masterbatches. Utility Model Content
