可降解颗粒是怎么来的？实际上，据有关资料查看，可以知道，可降解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。

How do degradable particles come from? In fact, according to relevant data, it can be seen that degradable particles are mainly made of natural polymers (such as starch, cellulose, chitin) or agricultural by-products through microbial fermentation or synthesis of biodegradable polymers.

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。

For example, thermoplastic starch plastics, aliphatic polyester, polylactic acid, starch/polyvinyl alcohol, etc. belong to this category of plastics, which are mainly used to make degradable plastics. Degradable plastics refer to a class of plastics whose properties of products can meet the use requirements, remain unchanged during the storage period, and can be degraded into substances harmless to the environment under natural environmental conditions after use.

可降解颗粒一般可分为光降解塑料、生物降解塑料、光/生物降解塑料和水降解塑料等四大类：光降解塑料是将光敏剂掺在塑料中，在太阳光照射作用下，塑料逐渐分解。但其缺点是，降解时间受到太阳光和气候环境的影响，因此无法控制。

The degradable particles can generally be divided into four categories: photo degradable plastics, biodegradable plastics, photo/biodegradable plastics and water degradable plastics. Photodegradable plastics are the plastics mixed with photosensitizers, and the plastics gradually decompose under the effect of sunlight. However, its disadvantage is that the degradation time is affected by sunlight and climate environment, so it cannot be controlled.

此类塑料贮存运输方便，应用范围较广。光/生物降解塑料，就是融合光降解塑料和生物降解塑料双重特点的塑料。

This kind of plastic is easy to store and transport, and has a wide range of applications. Photodegradable/biodegradable plastics are plastics that combine the dual characteristics of photo degradable plastics and biodegradable plastics.

可降解颗粒在性能、实用性、降解性、性上都有其优势。在性能上，可以达到或在某些特定领域超过传统塑料的性能；在实用性上，有着与同类传统塑料相近的应用性能和卫生性能。

Degradable particles have their advantages in performance, practicability, degradability and safety. In terms of performance, it can reach or exceed the performance of traditional plastics in some specific fields; In terms of practicality, it has similar application performance and hygienic performance with similar traditional plastics.

在降解性上，能在使用后，可以在自然环境下（特定微生物、温度、湿度）较快完成降解，并成为易被环境利用的碎片或气体，减少对环境的影响。

In terms of degradability, it can be quickly degraded in the natural environment (specific microorganisms, temperature, humidity) after use, and become easily used fragments or non-toxic gases to reduce the impact on the environment.

可降解颗粒时间是由构成塑料的成分所决定的，尤其是淀粉基可降解塑料它的降解速度非常快，而且降解后所生成的物质完全是可利用的，不会对环境造成污染！降解时间是可控的！您还有什么相关的问题，随时来网站http://www.1958666.com留言提出！

The time of degradable particles is determined by the composition of the plastic, especially the starch based degradable plastic, which degrades very quickly, and the substances generated after degradation are completely available, and will not pollute the environment! The degradation time is controllable! If you have any other questions, please come to the website at any time http://www.1958666.com Leave a message!
