生物降解资料远景一片大好,跟着能源涨价以及环境问题的日益凸显,范围内可降解生物资料、全生物降解资料替代传统石油产品的脚步呈现出逐步加快的趋势,预计还将出台相应的优惠政策和法律法规,鼓舞市场应用,生物降解资料的大规模应用远景乐观。生物降解资料包括用生物技术直接制取的高分子资料,如聚羟基脂肪酸酯(PHA)等;用生物技术制取的原料再经聚合得到的一类资料,如聚乳酸(PLA)、聚丁二酸丁二醇酯(PBS)、聚氨基酸等;此外还有淀粉基生物降解塑料、二氧化碳共聚物脂肪族聚碳酸酯(APC)等。

The prospect of biodegradable data is very good. With the rising price of energy and the increasingly prominent environmental problems, the pace of replacing traditional petroleum products with biodegradable and biodegradable data is gradually accelerating. It is expected that the government will also promulgate relevant preferential policies, laws and regulations to encourage market application and the prospect of large-scale application of biodegradable data. View. Biodegradable materials include macromolecule materials directly prepared by biotechnology, such as polyhydroxyalkanoate (PHA), polylactic acid (PLA), polybutylene succinate (PBS), polyamino acid, etc., and starch-based biodegradable plastics, carbon dioxide copolymer aliphatic polycarbonate (APC). And so on.
淀粉生物降解资料,是淀粉通过改性、接枝反应后与其他聚合物共混加工而成的一种塑料产品,在工业上能够代替一般通用塑料等,能够用作包装资料,防震资料,地膜,食品容器,玩具等。
Starch biodegradable material is a kind of plastic product which is prepared by blending starch with other polymers after modification and grafting reaction. It can replace general plastics in industry, and can be used as packaging materials, earthquake-proof materials, plastic film, food containers, toys and so on.
可降解颗粒
PLA是以乳酸为原料聚合生成的高分子资料,具有无毒、无刺激性、强度高、易加工成型和优良的生物相容性等特点,制品在使用后可彻底降解,因此,PLA是一种能真正达到生态和经济双重效应的生物环保资料,是近年来开发研讨比较活跃、发展比较快的生物降解塑料。聚丁二酸丁二醇酯由丁二酸和丁二醇经缩聚而得,是现在公认的归纳性能比较好的生物降解塑料。因为PBS归纳性能优异,性价比合理,用途极为广泛,可用于包装、餐具、化妆品瓶及药品瓶、一次性用品、农用薄膜、农药及化肥缓释资料、生物医用高分子资料等范畴。
PLA is a kind of macromolecule material synthesized from lactic acid. It has the characteristics of non-toxicity, non-irritation, high strength, easy processing and good biocompatibility. The products can be completely degraded after use. Therefore, PLA is a kind of bio-environmental protection material that can truly achieve the dual effects of ecology and economy. It is the most active and fastest-growing biodegradable plastic in recent years. Polybutylene succinate is obtained by condensation of succinic acid and butylene glycol. It is recognized as the best biodegradable plastics in the world. Because of its excellent inductive performance, reasonable cost performance and wide application, PBS can be used in packaging, tableware, cosmetics bottles and drug bottles, disposable medical supplies, agricultural films, slow-release materials of pesticides and fertilizers, biomedical polymer materials and other fields.
聚羟基脂肪酸酯属于天然高分子聚酯,是许多细菌在特定条件下合成的一种细胞内聚酯。已有超越90个属的细菌被发现能够合成超越150种以上不同结构的PHA。现在现已商品化的PHA产品主要有聚羟基丁酸(PHB)、羟基丁酸与羟基戊酸的共聚物(PHBV)和羟基丁酸与羟基己酸的共聚物(PHBHHx)。
Polyhydroxyalkanoate is a kind of natural macromolecule polyester. It is a kind of intracellular polyester synthesized by many bacteria under specific conditions. More than 90 genera of bacteria have been found to synthesize PHA with more than 150 different structures. At present, the commercialized PHA products mainly include Polyhydroxybutyric acid (PHB), copolymer of hydroxybutyric acid and hydroxy valeric acid (PHBV) and copolymer of hydroxybutyric acid and hydroxy hexanoic acid (PHBHx).
生物降解资料用途广泛,可彻底生物降解塑料原料及其制品,制品包括淀粉基全生物降解购物袋、连卷袋、平口袋、高性能生物降解保鲜袋、高淀粉含量的生物降解城市垃圾分类袋、生物基可降解快递袋、水溶性洗刷用包装袋、农用地膜、工业用包装袋、电子产品类包装袋、一次性快餐具、饮料瓶杯等制品。这些产品取材于玉米、木薯等天然植物,其间生物含量均大于50%,比较快在90天内可完成彻底降解。
Biodegradable materials are widely used and can be completely biodegradable plastic materials and products, including starch-based full biodegradable shopping bags, roll-up bags, flat bags, high-performance biodegradable fresh-keeping bags, high starch content biodegradable municipal garbage sorting bags, biodegradable express bags, water-soluble washing packaging bags, agricultural film, industrial packaging bags, electronic products. Such products as packaging bags, disposable snack utensils, beverage bottles and cups. These products are derived from natural plants such as maize and cassava. The biological content of these products is more than 50%. They can be completely degraded within 90 days at the fastest.
