【正文】 南京林業(yè)大學(xué) 本科畢業(yè)設(shè)計 題 目: 年產(chǎn)十七萬噸白卡紙涂布工段工藝設(shè)計 學(xué) 院: 專 業(yè) 學(xué) 號: 學(xué)生姓名: 指導(dǎo)教師: 職 稱: 二 O 一 五 年 月 日 1 摘 要 本次畢業(yè)設(shè)計的課題為 年產(chǎn)十七萬噸白卡紙涂布工段工藝設(shè)計 。 本次設(shè)計的流程為: (涂布白卡紙的一種,為了方便后文中統(tǒng)一稱為社會卡)的主要質(zhì)量指標(biāo)和關(guān)鍵的技術(shù)參數(shù); 工藝流程并進(jìn)行可行性論證; 涂料 進(jìn)行配比; 涂布對社會卡質(zhì)量的影響 ;; 。 工藝方面:本設(shè)計是刮刀涂布,正面兩次涂布(預(yù)涂 ,面涂),背面一次涂布,硬刮刀的工作原理,涂料上料循環(huán)流程。涂料的主要成分是顏料和膠黏劑,還有一些其他助劑 , 其中顏料有碳酸鈣和高嶺土,膠黏劑有膠乳、 淀粉、 CMC 等,其他助劑有分散劑、消泡劑和水等。根據(jù)車間實際生產(chǎn)調(diào)整,紙幅從硬壓光過來,先經(jīng)過預(yù)涂,然后經(jīng)九烘進(jìn)背涂,再經(jīng)面涂送至十烘 。本造紙車間可以生產(chǎn)不同克重的社會卡, 總的年產(chǎn)量為17 萬噸 。 通過本次設(shè)計,了解涂布白卡紙的生產(chǎn)工藝及所用設(shè)備,進(jìn)一步鞏固所學(xué)知識,為以后的工作及研究打下扎實的基礎(chǔ)。 關(guān)鍵詞: 社會卡 (涂布白卡紙 ) 造紙車間 涂布工段 2 Abstract The graduation design subject to an annual output of one hundred and seventy thousand tons of white cardboard coating production process design. The design process: 1 understand the social card (a, coated white card in order to facilitate the later in this paper unified called social card) of the main quality index and the key technical parameters。 the 2 preliminary design process and demonstrate the feasibility。 3 based on feasibility study to select reasonable coating ratio effects of 4 coated card。 understand the quality of society。 5 drawing of process flow chart。 6 design summary. Process: the design of blade coating, two coating (positive pre coating, surface coating, a coating on the back), the working principle of rigid blade, coating material circulation process. Coating is the main position of pigments and adhesive, and some other additives, wherein the pigment with calcium carbonate and clay, with latex adhesives, starch, CMC and other additives are dispersing agent, defoaming agent and water etc.. According to the plant production adjustment, paper from the hard pressure light e, pre painted, and then by nine drying into the back coating, then by a surface coating to the ten drying. The papermaking workshop can produce different weight of the social card, the total annual output of 170000 tons. Through the design, the production process of coated white cardboard and equipment for understanding, to further consolidate the knowledge, work and study for the future and lay a solid foundation.
