可降解顆粒是怎么來的？實(shí)際上，據(jù)有關(guān)資料查看，可以知道，可降解顆粒主要是由天然高分子（如淀粉、纖維素、甲殼質(zhì)）或農(nóng)副產(chǎn)品經(jīng)微生物發(fā)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.

如熱塑性淀粉塑料、脂肪族聚酯、聚乳酸、淀粉/聚乙烯醇等均屬這類塑料，主要用于制作可降解塑料，可降解塑料是指一類其制品的各項(xiàng)性能可滿足使用要求，在保存期內(nèi)性能不變，而使用后在自然環(huán)境條件下能降解成對環(huán)境無害的物質(zhì)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.

可降解顆粒一般可分為光降解塑料、生物降解塑料、光/生物降解塑料和水降解塑料等四大類：光降解塑料是將光敏劑摻在塑料中，在太陽光照射作用下，塑料逐漸分解。但其缺點(diǎn)是，降解時(shí)間受到太陽光和氣候環(huán)境的影響，因此無法控制。

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.

此類塑料貯存運(yùn)輸方便，應(yīng)用范圍較廣。光/生物降解塑料，就是融合光降解塑料和生物降解塑料雙重特點(diǎn)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.

可降解顆粒在性能、實(shí)用性、降解性、性上都有其優(yōu)勢。在性能上，可以達(dá)到或在某些特定領(lǐng)域超過傳統(tǒng)塑料的性能；在實(shí)用性上，有著與同類傳統(tǒng)塑料相近的應(yīng)用性能和衛(wèi)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，可以在自然環(huán)境下（特定微生物、溫度、濕度）較快完成降解，并成為易被環(huán)境利用的碎片或氣體，減少對環(huán)境的影響。

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.

可降解顆粒時(shí)間是由構(gòu)成塑料的成分所決定的，尤其是淀粉基可降解塑料它的降解速度非?？?，而且降解后所生成的物質(zhì)完全是可利用的，不會對環(huán)境造成污染！降解時(shí)間是可控的！您還有什么相關(guān)的問題，隨時(shí)來網(wǎng)站http://www.qylxschool.cn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.qylxschool.cn Leave a message!
