Applied Research into Enzymatic Dechroming of Ovine Offals 酶法脱铬在羊皮制革下脚料中的应用研究
The effect of steric hindrance on the performance of dechroming was obvious and increasing temperature and associative hydrochloric acid could alleviate the effect degree. The dechroming ability and destructiveness on the stability of collagen of acid groups were bigger than H+. 有机酸分子位阻对其脱铬性能影响较大,升高温度和与盐酸复配均可显著降低其影响程度;有机酸根的脱铬能力及对胶原结构的稳定性的影响均大于H+。
According to the research of the dechroming property of phosphoric acid, lactic acid and mixed acids, the effects of dechroming temperature, time and the offer of acids on the quantity of dechroming and collagen hydrolysis were studied to explore the dechroming mechanisms of each acid. 研究了磷酸、乳酸、混合酸的脱铬效果,通过对脱铬过程中的温度、酸用量及反应时间对脱铬及胶原水解的影响,探讨了不同酸的脱铬机理。
The effects of dechroming time, fatliquoring time and the amount of fatliquoring agents on the performances of the collagen fiber prepared finally were studied by orthogonal test to determine the best process conditions and explore the primary and secondary order of each factor. 通过正交试验,研究脱铬时间、加脂时间、加脂剂用量对丝状纤维制备的影响,优化工艺条件,了解因素影响的主次。
