        脂肪/ ring 族异氰 acid ester (ADI) is production high polyurethane ester core raw materials, its made polyurethane ester material formed is aerospace military industry, high 端装备, automotive and other industry development key/critical property 基础材 material. 我国曾先 rear 批准数 sleeve/set technology construction ADI plant/unit, 均因国 outer technology 封锁而搁 shallow. Wanhua Chemical 经 17 year 锲而不舍 努 force, 终于打破国 outer 70 year technology 垄断, formed development 出ADI full industry chain manufacturing technology, this polyurethane ester industry upper “明珠”. in upper 周召开 石化 industry innovation large upper, Wanhua Chemical vice president 华卫琦讲述 科技进步特 and other formed 果脂肪/ ring 族异氰 acid ester full industry chain manufacturing technology development process.

        ADI product technology 遭封锁

         polyurethane ester is 由异氰 acid ester (MDI, TDI, ADI) and more alcohol, type additives reaction formed polymer/macromolecule polymer, acid ester is polyurethane ester most core raw materials, its in aliphatic acid ester 统称ADI, its table/sheet property product types has 异佛尔 ketone 二异氰 acid ester (IPDI), 1,6-六亚甲基二异氰 acid ester (HDI) and ring 己基甲烷二异氰 acid ester (H12MDI). 以ADI made polyurethane ester material tool has its excellent anti-aging, resistant 暴晒, resistant yellowing property can, is aerospace military industry, high 端装备, automotive and other industry development key/critical property 基础材 material, is coating material, agent, 人造革 and other industry green rise grade key/critical raw materials, has polyurethane ester industry upper “明珠” 美誉.

         in ADI 3 代 table/sheet property product types in, IPDI is solid 体火箭推进 agent most solid agent, long by 巴黎统筹委员会限 made toward China export, outer technology and product 封锁, can by using/adopting property can relatively TDI solid system;H12MDI则 is made transparent anti elastic 玻璃, high speed front 挡玻璃, optical sheet/slice, high 档氨纶 key/critical mono 体.

         due to ADI manufacturing industry chain process/workflow long, technology development difficult degree high, industrial 化70 more year, world upper can production HDI has Covestro and BASF, France 康瑞, Japan 南洋化 formed 4家 company, can production IPDI and H12MDI has Evonik and Covestro 2家 company.

         from basic combined formed research 起步

        我国曾数次批准引进 technology construction ADI plant/unit, 均因国 outer technology 封锁搁 shallow. “我们也曾 plan acquisition outer certain sleeve/set plant/unit 以期消化 absorption, by company 出巨资 rate lower remove, prohibited sales ADI raw materials to 万华. ”华卫琦 introduction 说.

        鉴于ADI in national defense and 国民经济 development in important function, 万华开始 17 year 锲而不舍 努 force.

        ADI manufacturing 包含HDI and add combined material, IP-IPN-IPDA-IPDI, MDA-H12MDA-H12MDI this 3 strip/profile industry chain. “ and front in MDI technology development upper 采取 消化 absorption again innovation different, in 2000 year front rear 选定ADI gas versus light gas technology 路线时, also has can and technology 信息, therefore this technology is from 实验室 basic combined formed research 开始, in 此基础 upper formed system concept design, engineering 化实验验证, most development industry formed sleeve/set technology. ”华卫琦 table/sheet 示.

         development core technology

        据华卫琦 introduction, development ADI full industry chain manufacturing technology main/primary light gas 化, add hydrogen, catalytic add hydrogen and reaction 精馏4项 core technology.

        一 is gas versus light gas made acid ester property technology. through improves light gas reaction 途径, development gas versus light gas made acid ester property technology. and liquid versus method versus ratio, technology rate improve/increase 3%~8%; solvent agent use amount decrease/reduce 50%, more energy saving; light gas amount decrease/reduce 30%, reaction more safety.

        二 is add hydrogen property technology. independent development high selection property, high rate composite/compounding nano add hydrogen catalytic agent, in 150 large gas pressure lower, IPDA收 rate to 95.5%, 氨基腈 content low 于0.4%, catalytic agent can stability 运转2 year above; development more solid add hydrogen reaction device and specialized additives system, will IPDA收 rate 进一步 improve/increase 至99% above, 氨基腈 content drop 至0.03% below/following.

        三 is ring high active property catalytic add hydrogen technology. technology add hydrogen pressure relatively low, can reduce plant/unit investment cost, using/adopting new development negative nano catalytic agent make product catalytic agent consumption decrease/reduce 1200元, add hydrogen selection property good, application property can more excellent. utilizing catalytic system and add hydrogen process, also development HTDA, H6XDA, ring amine and other product industrial technology.

        四 is reaction 精馏耦 combined technology. through development separation shrink combined reaction process, achieve reaction and high combined, make ketone mono 程转化 rate 达10%~15%, 异佛尔 ketone selection property can 达90%, meanwhile reaction hot used for product 精馏, energy saving significantly.

        打造ADI特 color industry 群

        依托 this innovation formed 果, 万华先 rear construction 5 10,000 tons / year HDI, 1.5 10,000 tons / year IPDI, 1 10,000 tons / year H12MDI, 2.5 10,000 tons / year IPDA, 1 10,000 tons / year H12MDA and other industrial plant/unit, formed world upper product types most full, industry chain most 完整, technology ADI特 color industry 群, currently 万华ADI series product market has rate full 球第二. 截至2019 year 11 month, achieve sales 收入120 100 million yuan, 利税52 100 million yuan.

        万华ADI project formed 功实施, 打破 国 outer company for ADI series product full industry chain manufacturing technology long 达70 year 垄断, make formed is world 唯一掌握 full industry chain MDA-H12MDA-H12MDI, world 第二家掌握 full industry chain IP-IPN-IPDA-IPDI, inner 唯一掌握HDI and material and other core technology enterprise, achieve aerospace military industry, high 端装备 and other field/area key/critical Raw Materials Domestic independent supply, is 打造国之 heavy device provide has force 支撑.
