甲壳素,又称壳聚糖,是一种多分子聚合物,广泛存在于自然界中,是甲壳类动物、软体动物、昆虫等角质层的主要成分,是地球上除植物以外的第二大纤维源。甲壳素无毒、无味、耐碱、耐热、耐晒、耐腐蚀,不怕虫蛀,在生产和生活领域具有十分广泛的用途。现国内外对甲壳素的研究、生产和应用十分重视,已在印染、纺织、涂料、医药、食品包装、污水处理等200多个领域应用,其应用范围还在不断扩大。如德国和日本将甲壳
Chitin, also known as chitosan, is a kind of multi-molecular polymer which is widely found in nature and is the main component of crustaceans, molluscs, insects and other cuticles. It is the second largest fiber on the earth except plants source. Chitin is non-toxic, tasteless, alkali-resistant, heat-resistant, light-fast, corrosion-resistant and insensitive to insects and has a very wide range of uses in the field of production and life. At home and abroad, the research, production and application of chitin attach great importance. It has been applied in more than 200 fields such as printing and dyeing, textile, coating, medicine, food packaging and sewage treatment, and its application range is still expanding. Such as Germany and Japan will be carapace
