Abstract
Description
Technical Field
[0001] This utility model relates to the field of latex filament production technology, specifically to a stirred reaction vessel for latex filament production. Background Technology
[0002] In the production of latex threads, it is usually necessary to mix the latex solution with solid additives (such as sulfur, ZnO, etc.) and then carry out a stirring reaction. However, the stirred reaction vessel in the existing technology has the following problems: 1. Solid additives are prone to clumping: When solid additives are added to the reaction vessel, they are prone to clumping due to their large particle size or moisture absorption, resulting in uneven dispersion. This not only affects the mixing effect but may also cause uneven vulcanization, ultimately reducing the performance of the latex filaments. 2. Low mixing efficiency: Traditional reactors usually directly add solid additives into the reactor without pretreatment devices, resulting in low mixing efficiency between solid additives and latex liquid, prolonged reaction time, and reduced production efficiency.
[0003] Therefore, we propose a stirred reactor for latex filament production. Utility Model Content
