This article will introduce the definition, characteristics, and application fields of degradable particles, and explore their potential in promoting environmental protection and sustainable development.

可降解颗粒的定义和特点

Definition and characteristics of degradable particles

可降解颗粒是一种由可降解材料制成的微小颗粒，其主要特点包括：

Degradable particles are small particles made of degradable materials, and their main characteristics include:

1.1 可降解性：可降解颗粒采用可降解材料制造，具有良好的生物降解性能。在适当的环境条件下，它们可以被微生物分解和降解，更终转化为的物质，减少对环境的污染。

1.1 Degradability: Degradable particles are made of biodegradable materials and have good biodegradability. Under appropriate environmental conditions, they can be decomposed and degraded by microorganisms, ultimately transforming into non-toxic substances, reducing environmental pollution.

1.2 替代传统材料：可降解颗粒可以作为一种替代传统塑料和其他不可降解材料的解决方案。与传统材料相比，可降解颗粒在生产、使用和处理过程中能够减少对环境的负面影响。

1.2 Alternative to traditional materials: Degradable particles can serve as a solution to replace traditional plastics and other non degradable materials. Compared with traditional materials, degradable particles can reduce negative environmental impacts during production, use, and treatment processes.

1.3 多样化的材料选择：可降解颗粒可以使用各种可降解材料制备，如生物基聚合物、淀粉基材料、聚乳酸等。这种多样性为不同应用领域提供了选择和灵活性。

1.3 Diversified material selection: Biodegradable particles can be prepared using various biodegradable materials, such as bio based polymers, starch based materials, polylactic acid, etc. This diversity provides choices and flexibility for different application fields.
