Description
技术领域technical field

背景技术Background technique
轻质印刷纸作为一种新型的印刷用纸，因其具有较高的松厚度、挺度、不透明度，印刷适性好，越来越广泛地用于书刊的印刷。目前出版社所用的印刷纸，绝大部份还是使用双胶纸；部分高档印刷品虽然使用轻型文化纸（蒙肯纸），也是高价向国外进口；据统计，我国每年向国外进口双胶印刷纸160万吨，进口轻型高档文化纸50万吨，蒙肯纸30万吨，每年需耗用外汇153亿元。因此以国产轻型文化纸替代进口双胶纸和轻型文化纸，可为国家节约大量的外汇。目前国内生产轻质印刷纸企业比较少，而且这些企业生产的轻型纸大都是APMP 浆配抄部分针叶机械浆和部分针叶化学浆生产成本较高。As a new type of printing paper, lightweight printing paper is more and more widely used in the printing of books and periodicals because of its high bulk, stiffness, opacity and good printability. At present, most of the printing paper used by publishing houses still use offset paper; although some high-end printed products use light cultural paper (Monken paper), they are also imported at high prices; according to statistics, my country imports offset printing paper from abroad every year 1.6 million tons, import 500,000 tons of light high-grade cultural paper, 300,000 tons of Monken paper, and consume 15.3 billion yuan in foreign exchange every year. Therefore, replacing imported offset paper and light cultural paper with domestic light cultural paper can save a lot of foreign exchange for the country. At present, there are relatively few light-weight printing paper companies in China, and most of the light-duty paper produced by these enterprises is APMP pulp blended with some softwood mechanical pulp and some softwood chemical pulp. The production cost is relatively high.
