生物降解包装塑料研究生物降解包装塑料可在短时间内,生物降解塑料颗粒,在自然环境条件下即能分解的可降解的包装塑料,它是替代目前的常规塑料,解决“白色污染”的新方法,也是国内外学者研究的热点。生物降解材料的研究国内外已有研究报道。生物降解包装塑料有淀粉基生物降解塑料、微生物发酵合成生物降解材料、纤维素基生物降解塑料、光/生物降解塑料和人工合成生物降解材料等。

Research on biodegradable packaging plastics biodegradable packaging plastics can be biodegradable plastic particles in a short time, which can be decomposed under natural environmental conditions. It is a new method to replace the current conventional plastics and solve the "white pollution". It is also a research hotspot of scholars at home and abroad. The research of biodegradable materials has been reported at home and abroad. Biodegradable packaging plastics include starch based biodegradable plastics, biodegradable materials synthesized by microbial fermentation, cellulose based biodegradable plastics, light / biodegradable plastics and synthetic biodegradable materials.
可降解塑料主要分成以下几类:由微生物合成的生物降解塑料,降解塑料颗粒生产厂家,包括生物聚酯、生物纤维素、多糖类和聚氨基酸等,可降解塑料颗粒,是一类能被自然界中的微生物降解的塑料。
Degradable plastics are mainly divided into the following categories: Biodegradable Plastics synthesized by microorganisms, manufacturers of degradable plastic particles, including Bio polyester, bio cellulose, polysaccharides and poly amino acids. Degradable plastic particles are a kind of plastics that can be degraded by microorganisms in nature.
聚乳酸,是以微生物发酵产物乳酸为单体化学合成的。使用后可自动降解。
Polylactic acid is chemically synthesized with lactic acid as monomer. It can degrade automatically after use.
聚乳酸可以被加工成力学性能优异的纤维和薄膜,其强度大体与尼龙纤维和聚酯纤维相当。聚乳酸在生物体内可被水解成乳酸和乙yi酸,并经酶代谢为CO2和H2O,故可作为医学用材料。日本、美国已经利用聚乳酸塑料加工成手术缝合线、人造骨、人造皮肤。聚乳酸还被用于生产包装容器、农用地膜、纤维用运动服和被褥等。
Polylactic acid can be processed into fibers and films with excellent mechanical properties, and its strength is roughly equivalent to that of nylon fiber and polyester fiber. Polylactic acid can be hydrolyzed into lactic acid and ethyl Yi acid in organism, and metabolized into CO2 and H2O by enzyme, so it can be used as medical materials. Japan and the United States have processed polylactic acid plastics into surgical suture, artificial bone and artificial skin. Polylactic acid is also used in the production of packaging containers, agricultural film, fiber sportswear and bedding.
由于目前产品生产成本偏高,加工性能,是否可用传统塑料机械加工还有待探讨,原料生产规模尚小,供应不足,致使下游开发减速,缺乏资金、人才以及产业政策的支持使得降解以及生物基**不能被在价格上正确反映,肇庆降解塑料颗粒,导致生物基降解材料还没有实现大规模的生产。
At present, due to the high production cost and processing performance of the products, whether the products can be processed by traditional plastic machinery remains to be discussed. The production scale of raw materials is still small and the supply is insufficient, resulting in the slowdown of downstream development. Due to the lack of funds, talents and the support of industrial policies, the degradation and bio based * * can not be correctly reflected in the price. Zhaoqing degraded plastic particles, As a result, bio based degradable materials have not been produced on a large scale.
生物基可降解塑料。生物基塑料是由生物体或其他再生资源直接合成的具有塑料特性的高分子材料。以可再生资源为原料的生物基塑料,生物分解后不增加环境压力,生命周期中为零排放。
Biodegradable plastics. Bio based plastics are polymer materials with plastic properties directly synthesized by organisms or other renewable resources. Bio based plastics with renewable resources as raw materials do not increase environmental pressure after biodegradation, and have zero emission in the life cycle.
