          可降解塑料袋的材質
          發布于:2022/08/13 隨著國家對環境保護的日益重視,每天隨便使用的塑料袋,給環境帶來了嚴重的問題和負擔。未來對可降解塑料袋的需求將繼續增加。塑膠袋分為兩類,一類是可降解塑料袋,這種購物袋是環保的,不會對環境造成任何污染和危害;另一類是不可生物降解的購物袋,即普通購物袋。購物袋。由于企業不可降解的塑料袋,對環境問題造成影響很大的危害,現在社會人們更喜歡使用可降解塑料袋。
          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產過程中,可以加入一定量的添加劑,使其穩定性降低,在自然環境中更易降解的塑料。隨著科學技術的發展,各種取代傳統聚乙烯塑料的材料應運而生,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,可替代傳統PE塑料袋??山到馑芰洗驯粡V泛應用:主要應用于農膜、各種塑料袋、垃圾袋、購物袋、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細菌、霉菌(真菌)和藻類等天然微生物的作用下降解的一類塑料。理想的生物技術降解塑料是性能優良的高分子材料,丟棄后可被環境影響微生物可以完全進行分解,無機化成為研究自然界碳循環的組成一個部分。“紙”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,生物技術降解以及塑料是兼具“紙”和“合成一個塑料”特性的高分子復合材料。生物降解塑料可分為完全生物降解塑料和破壞性生物降解塑料。
          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.
          破壞性生物降解塑料:破壞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.
          完全可生物降解塑膠:完全可生物降解塑膠主要由天然聚合物(例如淀粉、纖維素、甲殼素)或農業副產品經微生物發酵或合成生物降解聚合物制成,例如熱塑性淀粉塑膠、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.
          可降解塑料袋又稱可生物降解購物袋,是由植物淀粉、玉米粉等植物中提取的材料可以制成,這些原材料不會對人體和環境造成任何危害。
          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.
          使用可降解購物袋可在垃圾填埋場處理。購物袋只需要一段時間就降解成生物顆粒,然后被土壤物質吸收??山到馑芰洗粌H對環境沒有任何影響,而且可以用作植物和作物的肥料,促進植物的生長。
          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,現在可降解購物袋的使用很流行,不可降解購物袋的使用正在逐漸減少。不可降解的購物袋會對人體健康和生態環境問題造成非常大的危害。
          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.
