我们都知道,现在生物降解材料的分类繁多,对于不同的客户需求,都有相应的产品可供选择。其中PLA就是不少客户朋友想要弄清楚的。那么,生物降解材料中的PLA是什么呢?来看看生物降解颗粒厂家在下文中给出的详细介绍吧。

As we all know, there are many kinds of biodegradable materials. For different customer needs, there are corresponding products to choose from. PLA is what many customers and friends want to find out. So, what is PLA in biodegradable materials? Let's take a look at the detailed introduction given by biodegradable particle manufacturers below.
聚乳酸,又称聚丙交酯,是一种新型的可生物降解材料。聚乳酸通过生物发酵产生的乳酸聚合成可生物降解的塑料,具有良好的生物降解性和生物相容性。聚乳酸的原料主要来自可再生植物资源(如玉米、木薯、甘蔗等)中的糖类。)
Polylactic acid, also known as polylactide, is a new biodegradable material. Polylactic acid polymerizes into biodegradable plastics through lactic acid produced by biological fermentation, which has good biodegradability and biocompatibility. The raw materials of polylactic acid mainly come from sugars in renewable plant resources (such as corn, cassava, sugarcane, etc.)

PLA的材料优势有哪些?
What are the material advantages of PLA?
1.PLA具有很强的拉伸强度和延展性,良好的力学和物理性能;
1. PLA has strong tensile strength and ductility, and good mechanical and physical properties;
2.聚乳酸(PLA)可以被自然界的微生物完全降解,不会造成温室效应和任何固体废弃物污染;
2. Polylactic acid (PLA) can be completely degraded by natural microorganisms and will not cause greenhouse effect and any solid waste pollution;
3.良好的降解性和相容性;
3. Good degradability and compatibility;

4.它具有良好的透氧性和透气性,还具有隔离异味的特性;
4. It has good oxygen permeability and air permeability, and has the characteristics of isolating peculiar smell;
5.焚烧聚乳酸PLA时,焚烧纸的热值与焚烧的热值相同,是焚烧传统塑料(PE材料)的一半,焚烧PLA不会释放出有毒有害气体和硫化物、氮化物等化学物质。
5. When burning PLA, the calorific value of incineration paper is the same as that of incineration, which is half of that of traditional plastics (PE materials). Incineration of PLA will not release toxic and harmful gases, sulfides, nitrides and other chemicals.
