1、日产120吨双面胶板印刷纸抄纸车间初步设计摘要本设计是设计一个日产120吨的双面胶板印刷纸厂，重点是设计抄纸车间。纸机采用2640mm长网多缸纸机，生产定量为80g/m2的B等双胶纸。双面胶版纸主要用于印制画册、图片等。胶版纸质地紧密，伸缩性较小，抗水能力强，可以有效地防止多色套印时的纸张变形、错位、拉毛、脱粉等毛病。能给印刷品保持较好的色质纯度。因而发展前景广泛。原料采用硫酸盐木浆以4：6的比例配抄麦草浆，均采用漂白浆，使得浆的白度在85以上。在经过湿纸成形、压榨、烘干、施胶、压光等程序，便可制成成品纸。纸的其他技术指标要达到中华人民共和国行业标准QB1012-91的规定。设计核心部分是：厂
