项目摘要

Every year, large amount of chicken feathers are thrown away. For the effective use of chicken feathers, we extracted keratin proteins from the feathers and produced their films and fibers. Commercial application were also investigated. The results obtained in the present study are summarized as follows:The film extracted from the alkali solution had low strength and only showed the form of powders. The other film extracted by the reduction method was stiff and brittle. To improve mechanical properties, we prepared useful films by mixing with poly(vinylalcohol) (PVA)Quick method for testing biodegradability was examined. The samples were put in the media including two liters of various soils, fertilizer, and enzymes. The media were damped at 20℃ and 30℃ The changes of film samples with time were monitored. In the medium including liquid fertilizer and the soil from field, film sample at 30℃ was decomposed for one month.Investigation for practical use: (1) The film mixed with PVA; although a little cloudy, strong film was obtained: (2) Formaldehyde absorbent; films were tested for the use of formaldehyde absorbent. As the result, although inferior to the chitin, good absorbency was obtained; (3) Forming agent; stirring the extracted solution made surfactant then tough bubble was obtained. We examined the use of this bubble to produce light concrete by mixing it during the process of concrete board production.

每年都有大量的鸡毛被扔掉。为了有效地利用鸡毛，我们从鸡毛中提取角蛋白并制备其薄膜和纤维。并进行了商业应用研究。本研究的主要结果如下：从碱液中提取的薄膜强度较低，仅呈粉末状。通过还原法提取的另一种膜是硬的和脆的。为了提高膜的力学性能，我们将聚乙烯醇（PVA）与膜混合，制备了有用的膜。将样品置于包括两升各种土壤、肥料和酶的培养基中。在20℃和30℃条件下对介质进行润湿，监测薄膜样品随时间的变化。在含有液体肥料和田间土壤的介质中，30℃下分解一个月的薄膜样品，实际用途：（1）与PVA混合的薄膜，虽然有点浑浊，但得到了坚固的薄膜;（2）甲醛吸收剂，对薄膜进行了甲醛吸收剂的使用试验。结果表明，虽然不如甲壳素，但具有较好的吸水性;（3）成型剂，将提取液搅拌制成表面活性剂，得到坚韧泡沫。我们研究了在混凝土板生产过程中通过混合这种气泡来生产轻质混凝土。
