The SOE second-generation polystyrene (PS) complete sets of technological equipment independently developed by Quanzhou Quangang Marine Polyphenyl Resin Co., Ltd. have reached the world's advanced level, and a considerable part of the technology has achieved localization.
It is reported that China's domestic research and development of polystyrene (PS) sets of process technology and equipment are quite mature. The most important feature of this complete set of technical equipment is that the main reactors and synthetic routes are all independently designed and manufactured by China. The gravity gravity piston flow reactors of the core equipment are fully domesticated and 100% of all components on the reactor are domestically produced. Its machinery and equipment totaled 342 sets, of which 268 sets were domestically produced, localization rate was 78.36%, localization rate of instrumentation control equipment was 76.35%, and localization rate of electrical equipment was 81%.
The complete set of technical equipment has the world's most advanced PS process flow and configuration: independent development of a backflow-free PS bulk polymerization process that can fundamentally improve the relative molecular mass distribution of the product; independently developed large-volume vertical reactor, can provide Reasonable residence time, so as to obtain a better operating temperature, further improve the relative molecular mass distribution of the product; not only adopts a large-capacity prepolymerization reactor, but also adopts a high-impact double-kettle structure; the circulation liquid adds a processing device; design A variety of additive inlets, and the use of a variety of additives. These configurations and technologies are more conducive to producing high-quality products and developing more products that are more suitable for users.
