This application relates to the field of plasma reaction devices and discloses a multi-chamber plasma experimental system based on unified electrode spacing adjustment. The system includes a first plastic plate, with uniformly distributed reaction vessels fixedly connected to the top of the first plastic plate. Telescopic vessels are slidably connected to the inner diameter of each reaction vessel, and second plastic plates are fixedly connected to the top of each telescopic vessel. A sample inlet is fixedly connected to the bottom of each reaction vessel, penetrating the first plastic plate. The system also includes a reaction control system comprising an inlet control module, a sample inlet control module, and a metal plate distance control module. The distance between the second and first plastic plates is adjusted via the metal plate distance control module, thereby adjusting the position of the metal plates and thus the discharge spacing. Real-time control of various reaction conditions in each reaction vessel allows for simultaneous degradation experiments of the same pollutant under different conditions, facilitating control experiments.

This invention discloses a polymer ring-opening polymerization reaction control system based on high-viscosity rheological control, relating to the field of high-viscosity polymerization control technology, and specifically to the reaction control of the high-viscosity final stage of ring-opening polymerization of medical absorbable polymers PPDO or PGLA. A micro-bypass rheological measurement loop is installed alongside the main process to periodically collect fast variables and obtain reference viscosity point, shear consistency index, differential pressure drift, response time, and other health indicators. The bypass is isolated in case of abnormalities. Based on fast variable prediction and combined with health indicator calculations, a confidence weight is performed, and gated correction and parameter updates are executed, outputting a quality status estimate and reliable / suspicious / unusable tags. Trajectory control is performed under constraints such as temperature, torque, and differential pressure, with incremental control limited by tags. A degradation-cleaning-recovery state machine is triggered and an event log is recorded. This scheme can suppress false signal-driven processes, reduce the risk of deviation and loss of control, improve batch pass rate and closed-loop availability, and support continuous production traceability and operation and maintenance management.
