生物降解颗粒应用塑料的主要用途

生物降解颗粒应用塑料是指自然界中存在的微生物，如土壤或沙质土壤，在堆肥条件或厌氧消化条件等特定条件下降解，后期完全转化为二氧化碳、甲烷、水等物质。元素矿化无机盐以及新型生物质塑料。下面来讲讲生物降解颗粒应用塑料的主要用途的相关内容。

Biodegradable particle applied plastics refer to microorganisms existing in nature, such as soil or sandy soil, which degrade under specific conditions such as composting conditions or anaerobic digestion conditions, and are completely transformed into carbon dioxide, methane, water and other substances in the later stage. Element mineralized inorganic salts and new biomass plastics. Now let's talk about the main uses of biodegradable particles in plastics.

包装和其他一次性用品

Packaging and other disposable items

塑料的主要用途之一是作为包装，包装在废弃物中占很大比例。减少包装产生的塑料废物对全球塑料污染具有重要的积极作用。可生物降解塑料（纤维素基材料）的塑料包装可以替代食品包装等传统塑料。此外，可生物降解塑料还可用于许多一次性塑料制品，如吸管、牙签、棉签和零售袋等。

One of the main uses of plastics is as packaging, which accounts for a large proportion of waste. Reducing plastic waste from packaging plays an important and positive role in global plastic pollution. Plastic packaging of biodegradable plastics (cellulose based materials) can replace traditional plastics such as food packaging. In addition, biodegradable plastics can also be used in many disposable plastic products, such as straws, toothpicks, cotton swabs and retail bags.

农用地膜

agricultural film

农用地膜是农业生产系统的重要组成部分。它由不可生物降解的聚乙烯制成。风化破碎后留在田间的薄膜残留物会导致土壤塑料污染。可生物降解地膜设计用于农产品收获或使用后种植到地里，在自然条件下可被微生物降解的地膜无需拆除和处置。

Agricultural plastic film is an important part of agricultural production system. It is made of non biodegradable polyethylene. The film residues left in the field after weathering and crushing will lead to soil plastic pollution. Biodegradable plastic film is designed for agricultural products to be harvested or planted in the field after use. The plastic film that can be degraded by microorganisms under natural conditions does not need to be removed and disposed of.

与传统的聚乙烯地膜相比，可生物降解地膜具有相当的农艺性能，但其较高的成本以及农民对其性能的不确定性以及对土壤降解问题的认识导致了可生物降解地膜的广泛使用。使用受到阻碍。随着可生物降解塑料的发展和农民意识的提高，可生物降解地膜可以为农用聚乙烯地膜提供一种可行的替代品。

Compared with traditional polyethylene mulching film, biodegradable mulching film has considerable agronomic performance, but its high cost, farmers' uncertainty about its performance and their understanding of soil degradation lead to the wide use of biodegradable mulching film. Use is hampered. With the development of biodegradable plastics and the improvement of farmers' awareness, biodegradable plastic film can provide a feasible substitute for agricultural polyethylene film.

一般来说， 生物降解颗粒应用塑料的降解过程可分为生物降解、解聚、生物同化和矿化四个步骤。生物降解过程是导致表面降解的微生物生物膜的形成，其中聚合物材料分解成更小的颗粒。解聚是微生物分泌胞外酶，催化聚合物链解聚成寡聚体、二聚体或单体。生物同化是将小分子吸收到微生物细胞中并随后产生初级和次级代谢物。在

Generally speaking, the degradation process of biodegradable particles applied to plastics can be divided into four steps: biodegradation, depolymerization, biological assimilation and mineralization. The biodegradation process is the formation of microbial biofilm leading to surface degradation, in which the polymer material is decomposed into smaller particles. Depolymerization is an extracellular enzyme secreted by microorganisms that catalyzes the depolymerization of polymer chains into oligomers, dimers or monomers. Biological assimilation is the absorption of small molecules into microbial cells and the subsequent production of primary and secondary metabolites. stay

后期这些代谢物被矿化，后期产物CO2、CH4、H2O和N2形成并释放到环境中。此外，生物降解塑料聚合物的降解受非生物和生物因素的影响，其中非生物因素主要是指机械应力、光照或温度等参数，生物因素是指天然存在的微生物（如细菌、真菌和藻类）。

In the later stage, these metabolites are mineralized, and the later products CO2, CH4, H2O and N2 are formed and released into the environment. In addition, the degradation of biodegradable plastic polymers is affected by abiotic and biological factors, in which abiotic factors mainly refer to parameters such as mechanical stress, light or temperature, and biological factors refer to naturally occurring microorganisms (such as bacteria, fungi and algae).

问题就讲解到这里了，实际上生物降解颗粒的使用在某些方面还是存在一定的挑战性的，因此就需要使用者严格按照相关要求进行使用，当然在保证安全的基础上可以创新实验。更多关于该材料的内容就来关注我们网站 www.ucgmex.com吧！
