Shanghai Daoqin Plastics Co., Ltd.

        近 day, China 民营科技 promote 会主办 “30 10,000 tons / year styrene formed sleeve/set technology industrial application ” project formed evaluation in 京举行, 自科技部, chemical industry large 学, China chemical industry 学会, China chemical industry group company, 首都师范 large 学, 北京科技 large and other mono expert 们一致认 is, 由常州瑞华 chemical industry engineering technology corporation has company (below/following 简称瑞华 chemical industry) independent R&D 30 10,000 tons / year styrene formed sleeve/set technology, its main/primary indicators to inner water 平, 经济效益 and 社会效益 significantly.

         has expert toward table/sheet 示, technology innovation features is development low can consumption liquid versus 烷基化 combined formed and high true 空, low water ratio 乙苯绝 hot hydrogen reaction process, design 独特 乙苯脱 hydrogen high temperature system solution/scheme, R&D hydrogen reaction device, hot device and in hot device and other key/critical equipment, from improve/increase styrene production capacity 10%, long equipment cycle, plant/unit stability.

         value is, in recent years, 随 科学 technology 进步, 各行各业 迅猛 development, for polystyrene (PS) resin demand amount 越 越 large, formed for styrene demand amount increase.

        尽 tube/pipe styrene production can force and output/production volume has long development, due to styrene lower product development more fast, most 近10 year, styrene mono Imported amount 一直维持 in 350 10,000 tons / year 规模, inner styrene product 依然不 can meet/satisfy market demand, 缺口未 can to understanding.

         and meanwhile, year 产30 10,000 tons and above styrene plant/unit full using/adopting outer styrene process technology construction, outer technology 处于垄断 位, but also utilizing inner technology construction styrene plant/unit, especially is construction styrene plant/unit, in heavy can consumption material consumption high, 经济效益差 issues, therefore development technology large 规划化 styrene technology tool has important 意义.
