可降解颗粒随着科学技术的发展,社会进步!可降解颗粒非常普遍,但是你知道什么是可降解颗粒材料吗?那今天就让小编带你去了解一下吧!

Extrusion degradation particles with the development of science and technology, social progress! Degradable particles are very common, but do you know what degradable granular materials are? Then let Xiaobian take you to understand it today!
聚乳酸:聚乳酸。它是一种新型的生物基生物降解材料,由可再生植物资源(如玉米)中的淀粉原料制成。淀粉原料糖化得到葡萄糖,然后葡萄糖和某些菌株发酵制备高纯度乳酸,通过化学合成方法合成一定分子量的聚乳酸。它具有良好的生物降解性,使用后可在特定条件下被自然界中的微生物完全降解,终生产生二氧化碳和水,不污染环境,非常有利于保护环境,被公认为环保材料。
Polylactic acid: polylactic acid. It is a new type of bio based biodegradable material, which is made of starch from renewable plant resources (such as corn). Glucose was obtained by saccharification of starch, and then high purity lactic acid was prepared by fermentation of glucose and some strains. Polylactic acid with certain molecular weight was synthesized by chemical synthesis method. It has good biodegradability and can be completely degraded by microorganisms in nature under specific conditions after use. It can produce carbon dioxide and water for life without polluting the environment. It is very helpful to protect the environment and is recognized as an environmental protection material.
PBS:聚丁二酸丁二醇酯。白色颗粒是由琥珀酸和丁二醇缩聚合成的。树脂呈乳白色,无嗅无味。容易被自然界中的各种微生物或动植物中的酶分解代谢,更终分解成二氧化碳和水。它是一种典型的完全可生物降解的高分子材料。它具有良好的生物相容性和生物吸收性,耐热性好,热变形温度和产品使用温度可超过100℃。其合成原料的来源可以是石油资源或通过生物资源发酵获得。PBS是生物可降解塑料材料的。

PBS: polybutylene succinate. The white particles were synthesized by polycondensation of succinic acid and butanediol. The resin is milky white, odorless and tasteless. It is easy to be decomposed and metabolized by various microorganisms, animals and plants in nature, and finally decomposed into carbon dioxide and water. It is a typical biodegradable polymer material. It has good biocompatibility and bioabsorbability, good heat resistance, thermal deformation temperature and product use temperature can exceed 100 ℃. The source of its synthetic raw materials can be petroleum resources or obtained by fermentation of biological resources. PBS is a leader in biodegradable plastics.
聚己内酯。挤出降解颗粒它具有良好的生物降解性、生物相容性和无毒,广泛用作医用生物降解材料和药物控释系统,可应用于组织工程,并已作为药物缓释系统使用。
Polycaprolactone. Extrusion degradable granules have good biodegradability, biocompatibility and non toxicity. They are widely used as medical biodegradable materials and drug controlled release systems. They can be used in tissue engineering and as drug delivery systems.
聚羟基脂肪酸酯。它是由许多细菌合成的细胞内聚酯。它主要作为碳源和能源的储存物质存在于生物体中。它具有与合成塑料相似的物理和化学性质,以及许多合成塑料所不具备的优异性能,如生物降解性、生物相容性、光学活性、压电性、气体分离性等。多羟基脂肪酸酯在生物可降解包装材料、组织工程材料、缓释材料、电气材料和医用材料方面具有广阔的应用前景,但只有降低聚羟基脂肪酸酯的生产成本后,才有可能大规模应用。
Polyhydroxy fatty acid ester. It is an intracellular polyester synthesized by many bacteria. It mainly exists in organism as carbon source and energy storage material. It has similar physical and chemical properties as synthetic plastics, and many excellent properties that synthetic plastics do not have, such as biodegradability, biocompatibility, optical activity, piezoelectricity, gas separation, etc. Polyhydroxy fatty acid esters have broad application prospects in biodegradable packaging materials, tissue engineering materials, slow-release materials, electrical materials and medical materials. However, large-scale application of polyhydroxyalkanoates can only be achieved by reducing the production cost of polyhydroxyalkanoates.
PBAT:挤出降解颗粒聚己二酸/对苯二甲酸丁酯。PBAT是一种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,具有聚对苯二甲酸丁二醇酯和聚对苯二甲酸丁二醇酯的特性,具有良好的延展性和断裂伸长率,以及良好的耐热性和冲击性能。此外,它还具有优异的生物降解性,是生物降解塑料研究中更活跃的生物降解材料之一,具有较好的市场应用前景
PBAT: extrusion degradation particle poly (adipic acid) / butyl terephthalate. PBAT is a kind of thermoplastic biodegradable plastic, which is a copolymer of butylene adipate and butylene terephthalate. It has the characteristics of polybutylene terephthalate and polybutylene terephthalate, good ductility and elongation at break, as well as good heat resistance and impact properties. In addition, it has excellent biodegradability and is one of the most active biodegradable materials in the research of biodegradable plastics, and has a good market application prospect
