Shanghai Daoqin Plastics Co., Ltd.

“ in product property can, engineering application property can and production process and and other overall to 国际先进 water 平, independent made material system, foaming temperature technology ‘近零 defect ’ large thick degree combined formed one-time molding technology 国际领先……”12 month 9 day, from cationic 科博思 new material has company understanding to, for 轨道交 general purpose large thick degree one-time molding combined formed research project, 以著名材 material expert, China engineering 院院士张联盟 is formed evaluation small to upper evaluation. this innovation formed to industry expert can.

洛 cationic 科博思 company is cationic 市首家创业 sheet/plate upper company ——隆华科技 group (洛 cationic) corporation has company 控股子 company. this enterprise R&D resin is by 院士学者 likes, by is “ future 轨枕” product.

传统 iron 路轨枕 usually using/adopting mixed 凝土轨枕 and 木质轨枕. easy 腐蚀, fracture, use lifespan short, repair difficult. mixed 凝土轨枕 weight large, difficult, through 时振动 large, combined large degree and other. 科博思 company R&D resin 轨枕巧妙 solution series 传统材 material application 痛点.

据科博思 company engineering 师魏建国 introduction, resin 轨枕由 glass fiber reinforcement foaming polyurethane ester made formed, density has mixed 凝土轨枕 1/3, and versus 当, anti water resistant pressure 效果却 excellent 于木枕, 撑起数10吨 heavy 轨道车辆也 milli pressure.

as is rail transit new technology product resin 轨枕也 has short sheet/plate. due to production technology 限, inner outer resin using/adopting 三明治式 more 层黏结拼装. in use in, this type of 拼接 轨枕存 in lifespan short, can degree low and other disadvantages.

“实验 in, mixed 凝土轨枕 can to 200万次 resistant fatigue impact requirements, however resin can 承受10万次. ”魏建国 introduction 说, “ if long year use, can can cracking and 轨枕道钉 easy 松弛脱落 and other issues, formed safety 隐患. ”

针 for this technology bottle 颈, company resin formulation, resin and fiber low frequency 剪振浸渍 and other issues in 攻关, breakthrough foaming control, solid temperature degree degree and resin fiber uniform and other key/critical technology, achieve 30~300 mm combined formed one-time molding, in world scope/range inner rate 先掌握 large thick degree one-time molding processing technology, make resin 轨枕预期 lifespan long 至50 year above, in complex 特殊工况 lower ratio mixed 凝土轨枕 also resistant use.

据该 company 常务副 general manager introduction, currently product already used for heavy 庆朝天门 long large 桥, and 北京, 广州, deep 圳, 佛山, and other more rail transit project. lower 一步, company will add large product R&D and force degree, force China rail transit material rise grade.
