因为化学可降解塑料颗粒PLA由于自身存在一些缺陷,从而影响了其加工性能和应用,主要缺陷有:自身强度不高、脆性、阻透性差、耐热性差等。

The main defects are: low strength, brittleness, poor permeability, poor heat resistance and so on.
具有较高的拉伸强度、压缩模量,但质硬而韧性较差,缺乏柔性和弹性,极易弯曲变形;另外,化学可降解塑料颗粒PLA的化学结构缺乏反应性官能团,也不具有亲水性,降解速度需要控制,因此有必要对化学可降解塑料颗粒PLA进行改性。
It has high tensile strength and compression modulus, but it is hard and poor toughness, lack of flexibility and elasticity, and easy to bend; in addition, the chemical structure of chemical degradable plastic particles PLA lacks reactive functional groups and hydrophilicity, so the degradation rate needs to be controlled, so it is necessary to modify the chemical degradable plastic particles PLA.
在石油资源日益枯竭和全球提倡低碳环保的大背景下,生物塑料在资源利用和可降解等方面比传统塑料具有的优势。
In the context of the depletion of oil resources and the global promotion of low-carbon environmental protection, bioplastics have more advantages than traditional plastics in resource utilization and degradability.
作为生物塑料家族中的当家品种,PL化学可降解塑料颗粒以其良好的相容性和可降解性受到各方青睐。聚乳酸也称为聚丙交酯,是以乳酸为原料生产的新型聚酯材料。
As the leading variety in the bioplastics family, PL chemical degradable plastic particles are favored by all parties for their good compatibility and degradability. Poly (lactic acid), also known as poly (lactide), is a new type of polyester material produced from lactic acid.
