生物降解颗粒广泛使用,完全生物降解塑料原材料和产品,产品包括淀粉基可生物降解购物袋、连卷袋、平口袋,高性能生物可降解袋、高淀粉含量的可生物降解的城市垃圾分类袋、生物降解信使袋,水溶性洗袋、农用薄膜、工业包装袋,电子产品袋、一次性KuaiCanJu,喝杯等。产品。这些产品是由玉米和木薯等天然植物制成的,它们含有超过一半的生物成分,可以在90天内完全降解。
Biodegradable particles are widely used, fully biodegradable plastic raw materials and products, including starch based biodegradable shopping bags, rolling bags, flat bags, high-performance biodegradable bags, biodegradable municipal waste sorting bags with high starch content, biodegradable message bags, water-soluble washing bags, agricultural films, industrial packaging bags, electronic products bags, disposable kuaicanju, Have a drink, etc. Products. These products are made from natural plants such as corn and cassava, which contain more than half of the biological components and can be completely degraded in 90 days.
生物降解颗粒
在新的世纪,越来越严重的能源和环境问题让人们意识到环境保护的严重性,包装材料的消耗是巨大的,世界上的城市都被白色垃圾困扰着。因此,开发可生物降解材料的塑料包装是非常重要的,世界各国都在这方面做了大量的工作,并取得了可喜的成果。生物降解材料有多种实现方式,如采用天然原料加工;向树脂中加入淀粉等物质可以使材料被细菌分解。开发可水解的聚合物等。
In the new century, more and more serious energy and environmental problems make people realize the seriousness of environmental protection. The consumption of packaging materials is huge. Cities in the world are troubled by white garbage. Therefore, it is very important to develop the plastic packaging of biodegradable materials. Many countries in the world have done a lot of work in this field and achieved gratifying results. There are many ways to realize biodegradable materials, such as processing with natural raw materials; adding starch and other substances into the resin can make the materials decomposed by bacteria. Development of hydrolyzable polymers, etc.
合成高分子降解塑料实际上是化学合成的生物降解塑料,主要包括脂肪族聚酯(PCLS)、聚酰胺、多糖、聚乳酸共聚物等,已经开发出许多生物降解合成聚合物,聚乳酸(PLA)、聚乙烯醇(PVA)和聚己内酯(PCLS)聚合物。聚乳酸是由乳酸单体经特殊细菌转化成淀粉而聚合而成的。聚乳酸价格昂贵,主要用于医药。
Synthetic polymer degradable plastics are actually chemically synthesized biodegradable plastics, mainly including aliphatic polyesters (PCLS), polyamides, polysaccharides, polylactic acid copolymers, etc. many biodegradable synthetic polymers, such as polylactic acid (PLA), polyvinyl alcohol (PVA) and polycaprolactone (PCLS), have been developed. Polylactic acid is polymerized from lactic acid monomer converted into starch by special bacteria. Polylactic acid is expensive and mainly used in medicine.
