我们是造纸化学品技术开发中心的研究人员，从1985年开始就一喜从事造纸用变形淀粉的研究工作。至今已开发4个系列16个产品（其中4个列入国家级新产品）。多年的开发实践使我们认识到，开发产品要符合国情，要有特色；在制造工艺上要有创新，并逐步形成系列化和专用化。选题要
We are researchers in the Paper Chemicals Technology Development Center. Since 1985, we have been engaged in the research of the deformed starch for papermaking. To date, four series of 16 products have been developed (4 of which are included in the national new product). Years of development and practice make us realize that the development of products to meet the national conditions, there must be distinctive; in the manufacturing process to be innovative, and gradually formed a series and specialization.
