生物降解顆粒的降解原理是怎樣的呢？實際上，生物降解塑料添加劑包含一種天然纖維質添加成分，該成分呈細小的顆粒形狀；既具有可生物降解特性又具有較高的透明度，從而對終端產品的物理性能影響甚微。該生物降解添加劑系列，是以聚烯烴為載體，配以一種天然植物纖維素的復合物。

What is the degradation principle of biodegradable particles? In fact, the biodegradable plastic additive contains a natural fibrous additive, which is in the shape of fine particles; It has both biodegradability and high transparency, so it has little impact on the physical properties of the end product. This series of biodegradable additives is a composite of polyolefin as carrier and natural plant cellulose.

另外，該復合物中還包含一種金屬離子預降解成分，以便為聚合物引發(fā)光降解的特性。所有的添加成分對環(huán)境都無害。含有生物降解添加劑的塑料薄膜具有生物降解的特性。

In addition, the composite also contains a metal ion pre degradation component, so as to generate light degradation characteristics for the polymer. All additives are harmless to the environment. The plastic film containing biodegradable additives has the characteristics of biodegradation.

當其被人們使用并拋棄之后，例如在垃圾堆里，只要有微生物、溫熱、潮濕并有氧氣，塑料制品就會破裂并被分解。生物降解率很大程度上取決于堆場里的自然條件，比較理想的環(huán)境是微生物活躍、溫熱并且不太干燥。

When it is used and discarded by people, such as in the garbage dump, as long as there are microorganisms, warm, humid and oxygen, the plastic products will break and be decomposed. The biodegradation rate largely depends on the natural conditions in the storage yard. The ideal environment is that microorganisms are active, warm and not too dry.

生物降解顆粒的應用領域主要在哪里？實際上，生物降解顆粒主要用作農膜和生長容器。其他應用場合還比如草皮種植片，肥料包裝袋，以及農作物的擯釋材料等等。

Where are the main application fields of biodegradable particles? In fact, biodegradable particles are mainly used as agricultural film and growth containers. Other applications include turf planters, fertilizer bags, and waste materials for crops.

生物降解顆粒也可以在醫(yī)學領域發(fā)揮作用，如：醫(yī)用材料不僅要求有醫(yī)效，而且還要、五毒、無刺激性，與人體有良好的生物相容性。

Biodegradable particles can also play a role in the medical field. For example, medical materials are required not only to have medical efficacy, but also to be safe, toxic, non irritating, and have good biocompatibility with the human body.

醫(yī)用生物降解顆粒是指完成功能后，可被生物體內的溶解酶分解而吸收，生物降解塑料已經被廣泛用于手術縫合線，人造皮膚，矯形外科，體內藥物緩釋劑和吸收性縫合線等領域。

Medical biodegradable particles refer to those that can be decomposed and absorbed by dissolved enzymes in organisms after their functions are completed. Biodegradable plastics have been widely used in surgical sutures, artificial skin, orthopedics, drug release agents in vivo, absorbable sutures and other fields.
