可降解塑料颗粒主要是由天然高分子（如淀粉、纤维素、甲壳质）或农副产品经微生物发酵或合成具有生物降解性的高分子制得，如热塑性淀粉塑料、脂肪族聚酯、聚乳酸、淀粉/聚乙烯醇等均属这类塑料，主要用于制作可降解塑料，可降解塑料是指一类其制品的各项性能可满足使用要求，在保存期内性能不变，而使用后在自然环境条件下能降解成对环境无害的物质的塑料。下面为大家介绍关于可降解颗粒相关知识。

Degradable plastic particles are mainly made from natural polymers (such as starch, cellulose, chitin) or agricultural by-products through microbial fermentation or synthesis of biodegradable polymers, such as thermoplastic starch plastics, aliphatic polyester, polylactic acid, starch/polyvinyl alcohol, etc., which are all of these plastics and are mainly used to make degradable plastics. Degradable plastics refer to a class of products whose properties can meet the use requirements, It is a kind of plastic whose properties remain unchanged during the storage period, but can be degraded into environmentally harmless substances under natural environmental conditions after use. Now let's introduce the relevant knowledge about degradable plastic particles.

一、可降解塑料颗粒配方分析

1、 Formula analysis of degradable plastic particles

可降解塑料配方分析范围：

Analysis range of degradable plastic formula:

光降解型塑料、生物降解型塑料、光、氧化生物全面降解性塑料、二氧化碳基生物降解塑料、热塑性淀粉树脂降解塑料。

Photodegradable plastic, biodegradable plastic, light and oxidation biodegradable plastic, carbon dioxide based biodegradable plastic, thermoplastic starch resin degradable plastic.

、可降解塑料配方原理分析：

Principle analysis of degradable plastic formula:

降解过程主要涉及生物降解，光降解和化学降解，这三种主要降解过程相互间具有增效、协同和连贯作用。例如，光降解与氧化物降解常同时进行并互相促进；生物降解更易发生在光降解过程之后。

The degradation process mainly involves biodegradation, photodegradation and chemical degradation. These three main degradation processes have synergy, synergy and coherence. For example, photodegradation and oxide degradation often occur simultaneously and promote each other; Biodegradation is more likely to occur after the photodegradation process.
