生物降解颗粒比较符合绿色环保,生物降解颗粒是绿色环保带领者,淀粉基生物降解塑料,是淀粉经过改性、接枝反应后与其他聚合物共混加工而成的一种塑料产品,在工业上可以代替一般通用塑料等,可以用作包装材料,防震材料,地膜,食品容器,玩具等。
Biodegradable particles are more in line with green environmental protection. Biodegradable particles are the leader of green environmental protection. Starch based biodegradable plastics are a kind of plastic products made by blending starch with other polymers after modification and grafting reaction. They can replace general plastics in industry and can be used as packaging materials, shockproof materials, plastic films, food containers, toys, etc.

淀粉的性质与淀粉的相对分子质量、支链长度以及直链淀粉和支链淀粉的比例有关。实验证明,高直链含量的淀粉更适合于制备塑料,所得制品具有较好的机械性能目前淀粉塑料的力学性能已经基本达到传统塑料的标准,但因淀粉本身具有吸水性,所以在潮湿环境中材料会吸水导致力学性能严重下降,且淀粉含量越高,问题越严重,有些淀粉塑料甚至能完全溶与水。
The properties of starch are related to the relative molecular weight of starch, the length of amylopectin and the ratio of amylose to amylopectin. Experiments have proved that starch with high amylose content is more suitable for preparing plastics, and the products have better mechanical properties. At present, the mechanical properties of starch plastics have basically reached the standard of traditional plastics. However, because starch itself has water absorption, the mechanical properties of materials will be seriously reduced in humid environment due to water absorption, and the higher the starch content is, the more serious the problem is, Some starch plastics are even completely soluble in water.
所以,生物降解颗粒是符合绿色环保的。
Therefore, biodegradable particles are in line with the green environmental protection.
