International Forum on Appropriate Industrial Technology Held at New Delhi/Anand, India on November 20-30, 1978. Pulping Technology and Requirements and Potentialities of Developing Countries

摘要

A given paper product can be manufactured from many different pulp grades, used alone or in blends, with or without addition of fillers and chemicals. In addition, many pulp grades can be made from widely different species of trees or plants. The wide choice of technology thus offered is materially narrowed down by the limitations imposed by local conditions and especially by those prevailing in developing countries. When a choice must be made it helps to know a little about the processes available and be able to assess the applicability of each such process to the end product considered, the raw material available, the size of production desirable and the geographic and economical conditions at the site under consideration. It is the purpose of this document to provide such information.
