設(shè)計(jì)依據(jù)、指導(dǎo)思想 設(shè)計(jì)依據(jù) 吉林化工學(xué)院下發(fā)的畢業(yè)設(shè)計(jì)（論文）任務(wù)書(shū) 指導(dǎo)思想 本設(shè)計(jì)的指導(dǎo)思想是： 由國(guó)內(nèi)外丁苯橡膠生產(chǎn)技術(shù)的對(duì)比可知，而國(guó)內(nèi)丁苯橡膠 80%以上采用乳液聚合方法，所以本設(shè)計(jì)采用技術(shù)成熟完善的傳統(tǒng)乳液聚合方法，利用傳統(tǒng)乳液聚合生產(chǎn)技術(shù)，確保產(chǎn)品質(zhì)量高，生產(chǎn)過(guò)程安全。生產(chǎn)工藝 河南城建學(xué)院畢業(yè)設(shè)計(jì) II Abstract The design for the
