生物降解塑料的相关分类内容

生物降解是指自然界中存在的微生物在土壤和/或沙土等自然条件下，和/或堆肥条件或厌氧消化条件或水培养液等特定条件下的作用导致降解，并完全降解为二氧化碳(CO?)或/和甲烷(CH?)、水(H?O)及其所含元素的矿化无机盐，以及新的生物质塑料。而生物降解塑料是指在细菌、霉菌（真菌）和藻类等天然微生物的作用下降解的一类塑料。下面来讲解下生物降解塑料的相关分类内容吧。

Biodegradation refers to the degradation of microorganisms existing in nature under natural conditions such as soil and / or sandy soil, and / or composting conditions, anaerobic digestion conditions or water culture medium, which is completely degraded to carbon dioxide (co?) And / or methane (CH) Mineralized inorganic salts of water (H? O) and its elements, as well as new biomass plastics. Biodegradable plastics refer to a kind of plastics degraded by natural microorganisms such as bacteria, molds (fungi) and algae. Let's explain the relevant classification of biodegradable plastics.

根据原料来源，生物降解塑料可分为生物基生物降解塑料和石油化工基生物降解塑料两大类。

According to the source of raw materials, biodegradable plastics can be divided into two categories: Bio based biodegradable plastics and petrochemical based biodegradable plastics.

生物基可降解塑料主要可分为四类：一类是天然材料直接加工而成的塑料；二是通过微生物发酵和化学合成得到的聚合物；三是微生物直接合成的聚合物；第四类是通过将这些材料混合或将这些材料与其他化学合成的生物降解塑料混合而获得的生物降解塑料。

Biodegradable plastics can be divided into four categories: one is plastics directly processed from natural materials; The second is the polymer obtained by microbial fermentation and chemical synthesis; Third, polymers synthesized directly by microorganisms; The fourth category is biodegradable plastics obtained by mixing these materials or mixing these materials with other chemically synthesized biodegradable plastics.

石油化工类生物降解塑料是指石油化工单体经化学合成聚合而成的塑料，如PBAT、聚丁二酸丁二醇酯（PBS）、二氧化碳共聚物（PPC）等。

Petrochemical biodegradable plastics refer to plastics formed by chemical synthesis and polymerization of petrochemical monomers, such as PBAT, polybutylene succinate (PBS), carbon dioxide copolymer (PPC), etc.

根据生物降解工艺分类，生物降解塑料可分为完全生物降解塑料和破坏性生物降解塑料两大类。破坏性生物降解塑料目前主要有淀粉改性（或填充）聚乙烯PE、聚丙烯PP、聚氯乙烯PVC、聚苯乙烯PS等。

According to the classification of biodegradation process, biodegradable plastics can be divided into completely biodegradable plastics and destructive biodegradable plastics. At present, destructive biodegradable plastics mainly include starch modified (or filled) polyethylene PE, polypropylene PP, polyvinyl chloride PVC, polystyrene PS, etc.

全生物降解塑料主要由天然高分子（如淀粉、纤维素、甲壳素）或农副产品经微生物发酵或合成可生物降解的高分子材料制成，如热塑性淀粉塑料、脂肪族聚酯、聚乳酸、淀粉/聚乙烯醇等.属于这种塑料。

Fully biodegradable plastics are mainly made of natural polymers (such as starch, cellulose, chitin) or agricultural and sideline products through microbial fermentation or synthetic biodegradable polymer materials, such as thermoplastic starch plastics, aliphatic polyester, polylactic acid, starch / polyvinyl alcohol, etc It belongs to this kind of plastic.

以淀粉等天然物质为基础的生物降解塑料目前主要包括以下产品：聚乳酸（PLA）、聚羟基链烷酸酯（PHA）、淀粉塑料、生物工程塑料、生物通用塑料（聚烯烃和聚氯乙烯）

At present, biodegradable plastics based on natural substances such as starch mainly include the following products: polylactic acid (PLA), polyhydroxyalkanoate (PHA), starch plastics, bioengineering plastics and biological general plastics (polyolefin and polyvinyl chloride)

生物降解颗粒厂家提醒您，理想的生物降解塑料是性能优良的高分子材料，丢弃后可被环境微生物完全分解，然后无机化成为自然界碳循环的组成部分，所以这类材料如今发展的越来越好，更多的内容您就关注网站 www.ucgmex.com查看吧！

Biodegradable particle manufacturers remind you that the ideal biodegradable plastic is a high molecular material with excellent performance. After being discarded, it can be completely decomposed by environmental microorganisms, and then inorganic into a part of the natural carbon cycle. Therefore, this kind of material is developing better and better. For more content, please pay attention to the website www.ucgmex.com Com check it out!
