Technical Field

[0001] The utility model relates to the technical field of para-aramid fibers, and specifically relates to a high-temperature mixing device for NMP and CaCl2. Background Art

[0002] The technical field of para-aramid fibers mainly involves the research, production and application of a new type of high-tech synthetic fiber. This fiber, whose full name is poly(p-phenylene terephthalamide), is an artificially synthesized aromatic polyamide fiber.

[0003] The mixed solution of NMP and CaCl2 has extensive applications in chemical fields such as aramid fiber synthesis. The traditional preparation methods have problems such as uneven mixing and easy generation of impurities. It is necessary to develop a high-temperature mixing device for NMP and CaCl2, which is of great significance for improving product quality and production efficiency.
