美国威斯康星大学的化学家发展了一种无硫制浆造纸的新方法。该法以醋酸、醋酸酯和水为混合溶剂制造纸浆不仅在投资上远低于传统的硫酸盐制浆法 ,同时在减少环境污染上也较为有利 ,新方法生产的纸浆的质量也优于传统制浆法的产品。硫酸盐和亚硫酸盐制浆法多年来一直在造纸工业 Chemists at the University of Wisconsin have developed a new sulfur-free pulping process. The method of acetic acid, acetic acid ester and water as a mixed solvent manufacturing pulp not only in the investment far lower than the traditional sulfate pulping method, while reducing the environmental pollution is also more favorable, the quality of the pulp produced by the new method is also better than the traditional Pulp products. Sulphate and sulphite pulping have been in the paper industry for many years
