随着科技的发展,社会的进步!可降解颗粒已经非常普遍了,但是大家知道降解颗粒材料都有哪些种类吗?那么今天就由安徽鑫科生物环保有限公司带大家了解一下吧!

  With the development of science and technology, social progress! Degradable particles are very common, but do you know what kinds of degradable particles are there? Today, Anhui Xinke biological environmental protection Co., Ltd. will take you to know about it!
  PLA:聚乳酸。是一种新型的生物基及可生物降解材料,使用可再生的植物资源(如玉米)所提出的淀粉原料制成。淀粉原料经由糖化得到葡萄糖,再由葡萄糖及一定的菌种发酵制成高纯度的乳酸,再通过化学合成方法合成一定分子量的聚乳酸。其具有良好的生物可降解性,使用后能被自然界中微生物在特定条件下完全降解,更终生成二氧化碳和水,不污染环境,这对保护环境非常有利,是公认的环境友好材料。
  PLA: polylactic acid. It is a new type of bio based and biodegradable material, which is made of starch material proposed by renewable plant resources (such as corn). Glucose was obtained from starch by saccharification, and then high purity lactic acid was produced by fermentation of glucose and certain bacteria. Then polylactic acid with certain molecular weight was synthesized by chemical synthesis. It has good biodegradability, can be completely degraded by microorganisms in the nature under specific conditions after use, and finally generate carbon dioxide and water, not polluting the environment, which is very beneficial to the protection of the environment, is recognized as environmentally friendly materials.
可降解颗粒
  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合成而得,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,更终分解为二氧化碳和水,是典型的可完全生物降解聚合物材料。具有良好的生物相容性和生物可吸收性,耐热性能好,热变形温度和制品使用温度可以超过100℃。其合成原料来源既可以是石油资源,也可以通过生物资源发酵得到,PBS是生物降解塑料材料中的佼佼者。
  PBS: polybutylene succinate. White particles are synthesized by condensation polymerization of succinic acid and butanediol. The resin is milky white, odorless and tasteless. It is easy to be decomposed and metabolized by various microorganisms or animals and plants in nature, and finally decomposed into carbon dioxide and water. It is a typical biodegradable polymer material. It has good biocompatibility, bioabsorbability, good heat resistance, and the temperature of thermal deformation and product use can exceed 100 ℃. PBS is one of the best biodegradable plastic materials, which can be obtained from petroleum or fermentation of biological resources.
  PCL:聚己内酯。具有良好的生物降解性、生物相容性和无毒性,而被广泛用作医用生物降解材料及药物控制释放体系,可运用于组织工程已经作为药物缓释系统。
  PCL: polycaprolactone. It has good biodegradation, biocompatibility and nontoxicity, and is widely used as medical biodegradable materials and drug controlled release system, and it can be used in tissue engineering as drug release system.
  PHA:聚羟基脂肪酸酯。是由很多细菌合成的一种胞内聚酯,在生物体内主要是作为碳源和能源的贮藏性物质而存在,它具有类似于合成塑料的物化特性及合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秀性能。聚羟基脂肪酸酯在可生物降解的包装材料、组织工程材料、缓释材料、电学材料以及医疗材料方面有广阔的应用前景,但只有降低PHA 的生产成本后才可能大规模应用。
  PHA: polyhydroxyfatty acid ester. It is a kind of intracellular polyester synthesized by many bacteria. It exists mainly as a storage material of carbon source and energy in organism. It has many excellent properties, such as the physical and chemical characteristics similar to synthetic plastics and the biodegradability, biocompatibility, optical activity, piezoelectricity, gas separation and so on, which are not possessed by synthetic plastics. Polyhydroxy fatty acid esters have broad application prospects in biodegradable packaging materials, tissue engineering materials, slow-release materials, electrical materials and medical materials, but they can be widely used only after reducing the production cost of PHA.
  PBAT:聚己二酸/对苯二甲酸丁二酯。PBAT属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断裂伸长率,也有较好的耐热性和冲击性能;此外,还具有优良的生物降解性,是目前生物降解塑料研究中非常活跃和市场应用更好降解材料之一。
  PBAT: poly (adipic acid) / butylene terephthalate. PBAT is a thermoplastic biodegradable plastic, which is a copolymer of butylene adipate and butylene terephthalate. It has the characteristics of PBA and PBT. It has not only good ductility and elongation at break, but also good heat resistance and impact performance. In addition, it also has excellent biodegradability. It is the most active biodegradable material in the research of biodegradable plastics and the best degradation material in the market One of.
