环保问题越来越严峻,因此可降解塑料等环保资料受到更多的重视。那么,可降解塑料有哪些?

Environmental protection is becoming more and more serious, so more attention has been paid to environmental protection materials such as degradable plastics. So, what are the degradable plastics?
PLA:聚乳酸。是一种新型的生物基及可生物降解资料,运用可再生的植物资源(如玉米)所提出的淀粉质料制成。
PLA: PLA. It is a new type of bio-base and biodegradable material, which is made of starch material proposed by renewable plant resources such as corn.
淀粉质料经由糖化得到葡萄糖,再由葡萄糖及必定的菌种发酵制成高纯度的乳酸,再经过化学组成办法组成必定分子量的聚乳酸。其具有杰出的生物可降解性。
Glucose is obtained from starch by saccharification, then high purity lactic acid is produced by fermentation of glucose and certain strains, and then polylactic acid with certain molecular weight is formed by chemical composition. It has excellent biodegradability.
运用后能被自然界中微生物在特定条件下完全降解,终究生成二氧化碳和水,不污染环境,这对保护环境十分有利,是公认的环境友好资料。
After application, it can be completely degraded by microorganisms in nature under specific conditions, eventually generating carbon dioxide and water, and not polluting the environment. This is very beneficial to the protection of the environment, and is recognized as environmentally friendly information.
PBS:聚丁二酸丁二醇酯。白色颗粒,由丁二酸和丁二醇经缩合聚合组成而得,树脂呈乳白色,无臭无味,易被自然界的多种微生物或动植物体内的酶分解、代谢,终究分解为二氧化碳和水,是典型的可完全生物降解聚合物资料。
PBS: polybutylene succinate. White particles, which are made up of succinic acid and butanediol by condensation and polymerization, are milky white, odorless and odorless. They are easily decomposed and metabolized by enzymes in various microorganisms, animals and plants in nature, and eventually decomposed into carbon dioxide and water. They are typical biodegradable polymer materials.
具有杰出的生物相容性和生物可吸收性,耐热功能好,热变形温度和制品运用温度可以超越100℃。其组成质料来源既可以是石油资源,也可以经过生物资源发酵得到,PBS是生物降解塑料资猜中的佼佼者。
Excellent biocompatibility and bioabsorbability, good heat resistance, thermal deformation temperature and product application temperature can exceed 100 C. The material source of PBS is not only petroleum resource, but also fermentation of biological resource. PBS is the best guess of biodegradable plastics.
PCL:聚己内酯。具有杰出的生物降解性、生物相容性和无毒性,而被广泛用作医用生物降解资料及药物控制释放系统,可运用于组织工程现已作为药物缓释系统。
PCL: Polycaprolactone. With excellent biodegradability, biocompatibility and non-toxicity, it has been widely used as medical biodegradable data and drug controlled release system, and can be used in tissue engineering as drug controlled release system.
生物降解颗
PHA:聚羟基脂肪酸酯。是由很多细菌组成的一种胞内聚酯,在生物体内主要是作为碳源和动力的贮藏性物质而存在。
PHA: Polyhydroxy fatty acid ester. It is a kind of intracellular polyester composed of many bacteria. It exists mainly as a carbon source and a power storage material in organisms.
它具有类似于组成塑料的物化特性及组成塑料所不具备的生物可降解性、生物相容性、光学活性、压电性、气体相隔性等许多优异功能。聚羟基脂肪酸酯在可生物降解的包装资料。
It has many excellent functions, such as biodegradability, biocompatibility, optical activity, piezoelectricity, gas separation and so on. Polyhydroxyalkanoates in biodegradable packaging materials.
组织工程资料、缓释资料、电学资料以及资料方面有宽广的使用远景,但只有降低PHA 的生产成本后才或许大规模使用。
Tissue engineering data, slow-release data, electrical data and medical data have broad prospects for use, but only after reducing the cost of production of PHA may large-scale use.
PBAT:聚己二酸/对苯二甲酸丁二酯。PBAT归于热塑性生物降解塑料,是己二酸丁二醇酯和对苯二甲酸丁二醇酯的共聚物,兼具PBA和PBT的特性,既有较好的延展性和开裂伸长率。
PBAT: Polyadipic acid/butylene terephthalate. PBAT belongs to thermoplastic biodegradable plastics. It is a copolymer of butylene adipate and butylene terephthalate. It has the characteristics of PBA and PBT, and has good ductility and cracking elongation.
也有较好的耐热性和冲击功能;此外,还具有优良的生物降解性,是现在生物降解塑料研究中十分活泼和市场使用比较好降解资料之一
In addition, it has excellent biodegradability, which is one of the most active and best degradable materials in the research of biodegradable plastics.
