Aiming at the problems of color paste retention and pigment deposition easily occurring during the engineering scale-up of existing reactors in the pilot-scale technology for in-situ continuous polymerization of solution-dyed polyester, the CFD computer simulation method was adopted to determine the structural parameters of a stepwise precision-controlled reactor dedicated to preparing high-pigment-concentration polyester prepolymers with enhanced dispersion and low backmixing characteristics. A pilot-scale stepwise precision-controlled reactor for the 2000 t/a flexible experimental line of continuous polymerization of solution-dyed polyester was then developed.
Through pilot-scale production of in-situ continuous polymerization of solution-dyed polyester, the effect of the structural parameters of the stepwise precision-controlled reactor on the dispersion degree of ultrafine pigments in high-pigment-concentration polyester prepolymers was verified, and the flexible preparation and on-line addition efficient dispersion process for high-pigment-concentration polyester prepolymers was optimized.
Based on the computer simulation results and the thousand-ton-scale pilot-scale verification results, a stepwise precision-controlled reactor dedicated to the 100,000 t/a large-capacity production line was developed, and the flexible preparation and on-line addition efficient dispersion system for high-pigment-concentration polyester prepolymers was developed.
This dataset (2020YFB0311400-002 - Dataset for Preparation and On-line Addition Technology of High-Pigment-Concentration Polyester Prepolymers) mainly includes four categories of content: 1. Computer simulation data of the pilot-scale stepwise precision-controlled reactor for preparing high-pigment-concentration polyester prepolymers; 2. Computer simulation data of the stepwise precision-controlled reactor dedicated to preparing high-pigment-concentration polyester prepolymers for large-capacity production lines; 3. Pilot-scale verification data of the stepwise precision-controlled reactor dedicated to preparing high-pigment-concentration polyester prepolymers; 4. Development documents of the flexible preparation and on-line addition efficient dispersion system for high-pigment-concentration polyester prepolymers dedicated to large-capacity production lines. There are 58 files in total across these four categories.
