AI Technical Summary
Traditional amino resin production methods use batch reactors for high-temperature and high-pressure reactions, resulting in long reaction times, high energy consumption, and poor batch stability of products, making it difficult to meet the needs of large-scale continuous production.
By employing a microchannel reactor and a low-temperature catalyst, combined with a multi-stage series structure and a catalyst recovery system, low-temperature catalytic reaction and continuous operation are achieved, and automated monitoring is performed through a PLC controller.
It achieves efficient catalytic reaction under low temperature conditions, improves product quality and production efficiency, reduces catalyst usage and energy consumption, and enhances the stability and safety of the production process.
