摘　　要：本文研究工作主要是关于用铬饼制备铬鞣液及其应用。铬饼是废铬屑用酶处理后的副产品，铬饼可以生产环保胶黏液。铬饼含40％-50％的无机固体，这些无机固体中还含有12％～15％的氧化铬。制备的5种不同铬液用于猪皮鞣制，鞣制后的猪皮革进行一系列的化学、物理机械性能（14种参数）的测定，所得结果能够与常规铬鞣液鞣制后的猪皮革相比较。结果表明，制备的鞣液可用于白色革的生产，并且相关的化学、物理机械性能可以与常规舶铬鞣液鞣制后的革相媲美。The presented work deals with the application of chrome cake to prepare chrome tanning liquors. Chrome cake is a solid by-product after enzyme treatment of chrome shavings and creates grow-green sticky paste. Chrome cake consists from 40 %-50 % of inorganic solids, which contains 12%-15 % of chromic oxide. A total of 5 different chrome liquors were prepared. These were used to tan samples of hides-pigskins. The tanned pigskin leathers were subjected to a series （altogether 14） of chemical and physico-mechanical tests, and results were compared to results of pigskin leather tanned by standard operation chrome liquor. Tanning tests, executed on laboratory prove that prepared tanning liquors may be applied to tanning of white-hides. Leathers tanned by means of such liquors are comparable to leathers tanned and produced through usual operating procedures.
