可降解塑料袋的材质
发布于:2022/08/13 随着国家对环境保护的日益重视,每天随便使用的塑料袋,给环境带来了严重的问题和负担。未来对可降解塑料袋的需求将继续增加。塑胶袋分为两类,一类是可降解塑料袋,这种购物袋是环保的,不会对环境造成任何污染和危害;另一类是不可生物降解的购物袋,即普通购物袋。购物袋。由于企业不可降解的塑料袋,对环境问题造成影响很大的危害,现在社会人们更喜欢使用可降解塑料袋。
With the increasing attention of the country to environmental protection, the plastic bags used casually every day have brought serious problems and burdens to the environment. The demand for degradable plastic bags will continue to increase in the future. Plastic bags are divided into two categories. One is degradable plastic bags, which are environmentally friendly and will not cause any pollution and harm to the environment; The other is non biodegradable shopping bags, i.e. ordinary shopping bags. Shopping bag. As the non degradable plastic bags of enterprises cause great harm to environmental problems, people in the society now prefer to use degradable plastic bags.
可降解塑料是指在生产过程中,可以加入一定量的添加剂,使其稳定性降低,在自然环境中更易降解的塑料。随着科学技术的发展,各种取代传统聚乙烯塑料的材料应运而生,包括聚乙烯塑料、聚苯乙烯塑料、聚苯乙烯塑料和其他高分子材料,可替代传统PE塑料袋。可降解塑料袋已被广泛应用:主要应用于农膜、各种塑料袋、垃圾袋、购物袋、一次性餐具等。
Degradable plastic refers to the plastic that can be added with a certain amount of additives in the production process to reduce its stability and be more easily degraded in the natural environment. With the development of science and technology, a variety of materials replacing traditional polyethylene plastics have emerged, including polyethylene plastics, polystyrene plastics, polystyrene plastics and other polymer materials, which can replace traditional PE plastic bags. Degradable plastic bags have been widely used: mainly used in agricultural film, various plastic bags, garbage bags, shopping bags, disposable tableware, etc.
可生物降解塑料是指在细菌、霉菌(真菌)和藻类等天然微生物的作用下降解的一类塑料。理想的生物技术降解塑料是性能优良的高分子材料,丢弃后可被环境影响微生物可以完全进行分解,无机化成为研究自然界碳循环的组成一个部分。“纸”是典型的可生物降解材料,而“合成塑料”是典型的高分子材料。因此,生物技术降解以及塑料是兼具“纸”和“合成一个塑料”特性的高分子复合材料。生物降解塑料可分为完全生物降解塑料和破坏性生物降解塑料。
Biodegradable plastics are a kind of plastics degraded by natural microorganisms such as bacteria, molds (fungi) and algae. The ideal biodegradable plastics are high molecular materials with excellent performance. After being discarded, they can be completely decomposed by the microorganisms that can be affected by the environment. The inorganic has become a part of the study of the carbon cycle in nature. "Paper" is a typical biodegradable material, while "synthetic plastic" is a typical polymer material. Therefore, biotechnology degradation and plastics are polymer composite materials with the characteristics of "paper" and "synthetic plastic". Biodegradable plastics can be divided into completely biodegradable plastics and destructive biodegradable plastics.
破坏性生物降解塑料:破坏性生物降解塑料目前主要有淀粉改性(或填充)聚乙烯PE、聚丙烯PP、聚氯乙烯PVC、聚苯乙烯PS等。
Destructive biodegradable plastics: at present, destructive biodegradable plastics mainly include starch modified (or filled) polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), etc.
完全可生物降解塑胶:完全可生物降解塑胶主要由天然聚合物(例如淀粉、纤维素、甲壳素)或农业副产品经微生物发酵或合成生物降解聚合物制成,例如热塑性淀粉塑胶、脂肪族聚酯、聚乳酸、淀粉聚乙烯醇。
Fully biodegradable plastics: fully biodegradable plastics are mainly made of natural polymers (such as starch, cellulose, chitin) or agricultural by-products through microbial fermentation or synthetic biodegradable polymers, such as thermoplastic starch plastics, aliphatic polyester, polylactic acid, starch and polyvinyl alcohol.
可降解塑料袋又称可生物降解购物袋,是由植物淀粉、玉米粉等植物中提取的材料可以制成,这些原材料不会对人体和环境造成任何危害。
Biodegradable plastic bags, also known as biodegradable shopping bags, can be made from materials extracted from plants such as plant starch and corn flour. These raw materials will not cause any harm to human body and the environment.
使用可降解购物袋可在垃圾填埋场处理。购物袋只需要一段时间就降解成生物颗粒,然后被土壤物质吸收。可降解塑料袋不仅对环境没有任何影响,而且可以用作植物和作物的肥料,促进植物的生长。
Degradable shopping bags can be disposed of in the landfill. Shopping bags need only a period of time to degrade into biological particles, which are then absorbed by soil materials. Degradable plastic bags not only have no impact on the environment, but also can be used as fertilizer for plants and crops to promote the growth of plants.
因此,现在可降解购物袋的使用很流行,不可降解购物袋的使用正在逐渐减少。不可降解的购物袋会对人体健康和生态环境问题造成非常大的危害。
Therefore, the use of degradable shopping bags is very popular now, and the use of non degradable shopping bags is gradually decreasing. Non degradable shopping bags will do great harm to human health and ecological environment.
