1前言近几年在造纸界为了保护资源、防止气候变暖,采取了一系列的环境保护措施,其中包括鼓励企业增加废纸的使用率。另外,为了提高国际竞争力,目前的抄纸机、涂布机也日趋高速化,在日本到处可见高速、大型的抄纸机在运行。另一方面在质量上,随着多色印刷等印刷方式及高速印刷机的出现,对纸张的质量要求也越来越严格。在这样的背景下,荒川化学工业(株)进行了表面处理剂方面的研究开发。本文就新研发的分支型
1 Introduction In recent years, the paper industry has taken a series of environmental protection measures to protect resources and prevent global warming, including encouraging enterprises to increase the utilization rate of waste paper. In addition, in order to enhance international competitiveness, current papermaking machines and coating machines are also increasing in speed, and high-speed and large-scale papermaking machines are in operation throughout Japan. On the other hand, with the quality, with the multi-color printing and other printing methods and the emergence of high-speed printing presses, the quality of the paper is also more stringent requirements. Against this background, Arakawa Chemical Industries Co., Ltd. conducted a research and development on the surface treatment agent. This article on the newly developed branch
