After pletion drawing prepares materials, beating workshop process flow diagram, pipe graph and workshop layout. Finally plete the design specification pilation. Process: the design is to use 80% waste paper deinking pulp, 20% mechanical pulp for making. By AKD ,CS, neutral sizing agent, filling, and Internal glue and so on. Equipment: this design is adopted in paper machine named VOITH8200,which has 1400m/speed top speed of min. Workshop layout: to facilitate the operation of the machine and equipment installation, workshop, the rationality was designed with two layers of decorate, workshop area is 5916m2 and the main span of workshop is 24m, column space is 6m. Through this design, I understanding the production process and used equipment of newsprint, further consolidate the knowledge for the future work and study the solid foundation. Keyword： Newsprint， papermaking workshop， process balance calculation, equipment selection calculation, drawing of workshop arrangement. 目 錄 前 言 ............................................................................................................................................. 8 論 .......................................................................................................................................... 9 設(shè)計(jì)范圍 ............................................................................................................................ 9 設(shè)計(jì)指導(dǎo)思想 ..................................................................................................................... 9 2 工藝論證及流程設(shè)計(jì) .................................................................................................................. 9 新聞紙技術(shù)要求 ...................................................................................................................... 9 新聞紙的技術(shù)指標(biāo) ................................................................................................................ 10 纖維原料的選取與配比 ..........................................................................................................11 國(guó)內(nèi)外動(dòng)向 ............................................................................................................................ 12 施膠 ....................................................................................................................................... 12 施膠目的及方法 ............................................................................................................................................. 12 施膠劑 .............................................................................................................................................................. 13 中性施膠與堿性造紙 ..................................................................................................................................... 13 合成施膠劑的應(yīng)用 ......................................................................................................................................... 14 AKD 內(nèi)部施膠工藝 ......................................................................................................................................... 14 加填 ....................................................................................................................................... 15 加填目的和作用 ............................................................................................................................................. 15 填料的種類 ...................................................................................................................................................... 15 選用原則 ........................................................................................................................................................... 16 GCC 的性質(zhì) .................................................................................................................................................. 16 GCC 加填工藝 .............................................................................................................................................. 16 助留助濾劑 ............................................................................................................................ 17 目的和作用 ....................................................................................................................................................... 17 助留助濾劑的種類及助留體系 ..................................................................................................................... 17 助留體系的選擇 .............................................................................................................................................. 18 陰離子微粒助留系統(tǒng) ...................................................................................................................................... 18 Compozil 系統(tǒng)助留工藝 ..
