一种无盐无铬的无限期循环利用废液进行浸酸鞣制的制革工艺
摘要：
本发明提供了一种无盐无铬的无限期循环利用废液进行浸酸鞣制的制革工艺，其特征在于鞣制过程不使用铬，彻底解决了铬污染问题，且所有的无铬鞣废液全部无限期循环使用，实现了无铬鞣废液零排放，并适合制革厂家现有的大生产工艺流程。此外，在浸酸过程中不加入食盐，大量节约食盐及其它相关化学材料，节约食盐100％，节约其它相关材料40％-60％，节约能源25％左右。由此生产的成品革各项性能指标均达要求，并有效降低了成革松面率，提高了成革的紧实度。
摘要（英）：

The invention provides a leather manufacturing process by pickling and tanning a salt-free and chrome-free recycled waste liquid. The process is characterized in that no chrome is used in the tanning process, thus the problem of chrome pollution is solved thoroughly; all the chrome tanning-free waste liquid is recycled, thus zero discharge of chrome tanning-free waste liquid is realized; and the process is suitable for the existing large production process of leather factories. In addition, no salt is added in the pickling process, a large amount of salt and other related chemical materials can be saved, wherein the salt can be saved by 100%, and the other related chemical materials can be saved by 40%-60%, and the energy can be saved by 25% approximately. Each performance index of the finished leather manufactured by the process meets the requirements, the rate of loose surface of the finished leather is decreased effectively, and the compactness of the finished leather is improved.
