Description

Technical Field

[0001] This utility model belongs to the field of membrane fiber treatment technology, specifically, it relates to a membrane fiber etherification reaction device. Background Technology

[0002] Membrane fibers have wide applications in many industrial fields, such as textiles, filtration, and separation. Etherification is an important method for modifying membrane fibers. Through etherification, the physicochemical properties of membrane fibers, such as hydrophilicity and chemical resistance, can be improved, thereby expanding their application range.

[0003] In existing technologies, etherifying agents and catalysts are usually added directly to the reactor containing raw materials to facilitate the etherification reaction of membrane fibers. However, during the reaction of membrane fibers, it may not be convenient to mix the etherifying agent and catalyst first, making it difficult to ensure that the etherifying agent and catalyst are uniformly dispersed in the liquid raw materials of membrane fibers. Uneven mixing will cause the reaction to proceed at different rates in different areas, which can easily lead to incomplete reaction. Some areas may not react sufficiently due to insufficient concentration of catalyst or etherifying agent.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content
