由于下游过滤器和喷丝板的制约,纤维素溶解器需要用低黏度混合物操作一直制约着纤维素纺丝原液的质量和通过量。瑞士List公司开发了MasterConti工艺,消除了溶解工艺和下游工艺相互间的影响,从而克服了上述制约。该工艺已通过试验验证,现能用于新装置,也可用于扩大现有装置的产能。 Due to downstream filter and spinneret constraints, the need for a cellulose dissolver to operate with a low viscosity mixture has always limited the quality and throughput of the cellulose dope. The List Company of Switzerland developed the MasterConti process, which overcomes the above constraints by eliminating the mutual influence of the dissolution process and the downstream process. The process has been experimentally validated and is now ready for new installations as well as expanding the capacity of existing installations.
