可降解塑料顆粒主要由天然聚合物（如淀粉、纖維素、甲殼素）或農副產品經微生物發(fā)酵或合成可生物降解的聚合物制成，如熱塑性淀粉塑料、脂肪族聚酯、聚乳酸、淀粉/聚乙烯醇等.屬于這類塑料，主要用于制造可降解塑料。可降解塑料是指性能能滿足使用要求的一類產品，在儲存期間性能保持不變，但使用后在自然條件下可降解為對環(huán)境無害的物質的塑料。下面下介紹可降解塑料顆粒的相關知識。

Degradable plastic particles are mainly made of natural polymers (such as starch, cellulose, chitin) or agricultural and sideline products through microbial fermentation or synthesis of biodegradable polymers, such as thermoplastic starch plastics, aliphatic polyester, polylactic acid, starch / polyvinyl alcohol, etc It belongs to this kind of plastics and is mainly used to manufacture degradable plastics. Degradable plastic refers to a kind of product whose performance can meet the use requirements. Its performance remains unchanged during storage, but it can be degraded into environmentally friendly substances under natural conditions after use. The following describes the relevant knowledge of degradable plastic particles.

Photodegradable plastics, biodegradable plastics, light, oxidative biodegradable plastics, carbon dioxide based biodegradable plastics, thermoplastic starch resin degradable plastics.

可降解顆粒廠家提醒，降解過程主要涉及生物降解、光降解和化學降解，這三種主要降解過程相互之間具有協(xié)同、協(xié)同和連貫的作用。例如，光降解和氧化物降解往往同時發(fā)生，相互促進；在光降解過程之后更有可能發(fā)生生物降解。

Manufacturers of degradable particles remind that the degradation process mainly involves biodegradation, photodegradation and chemical degradation, and these three main degradation processes have synergistic, synergistic and coherent effects on each other. For example, photodegradation and oxide degradation often occur simultaneously and promote each other; Biodegradation is more likely to occur after the photodegradation process.
