  现代人类文明可以说是以化石能源为基础的。但近年来,随着这些不可再生资源的枯竭,在可预见的未来,人们将面临一场能源危机。另一方面,人们也遭受着他们带来的痛苦,如严重的空气污染,白色污染等。为了解决这些问题,人们开始转向新的领域,其中之一就是生物降解颗粒。

  Modern human civilization can be said to be based on fossil energy. But in recent years, with the depletion of these non-renewable resources, people will face an energy crisis in the foreseeable future. On the other hand, people also suffer from the pain they bring, such as serious air pollution, white pollution and so on. In order to solve these problems, people began to turn to new fields, one of which is biodegradable particles.
  可生物降解材料的出现打破了塑料=“一万年前”=污染的传统印象。顾名思义,可降解材料是在一定的条件下,经过一定的时间可以降解成小分子的材料。根据降解机理可分为三类:光降解材料、生物降解材料和光生物降解材料。
生物降解颗粒
  The emergence of biodegradable materials has broken the traditional impression that plastics = 10,000 years ago) = pollution. As the name implies, degradable materials can be degraded into small molecules under certain conditions after a certain period of time. According to the degradation mechanism, it can be divided into three categories: photodegradable materials, biodegradable materials and photobiodegradable materials.

  How much do you know about biodegradable particles?
  在早期,可降解的成分或光敏剂,如淀粉,被添加到传统塑料中,而不影响其功能。在自然条件下,可生物降解的组分首先降解,从而破坏整个产品结构,这不仅有利于减少塑料袋的“满天飞”,也有利于加速难降解组分的降解。但这种材料并不是完全可降解的,可能需要很长时间才能完全降解。
  In the early stage, degradable components or photosensitizers, such as starch, were added to traditional plastics without affecting their functions. Under natural conditions, biodegradable components are degraded first, thus destroying the whole product structure, which is not only conducive to reducing the "flying all over the sky" of plastic bags, but also conducive to accelerating the degradation of refractory components. But this material is not completely degradable, and it may take a long time to degrade completely.
  现在,一些完全可降解的材料可以取代或正在取代传统的工程塑料。接下来,我们将介绍一些我们可以在日常生活中接触到的生物降解材料。
  Now, some completely degradable materials can replace or are replacing traditional engineering plastics. Next, we will introduce some biodegradable materials that we can contact in our daily life.
  首先,淀粉基塑料。淀粉基塑料是我们生活中最常见的生物可降解材料,比如一些一次性餐具。如果你有合适的工具,它的主要成分,淀粉,也可以由你厨房里的淀粉制成。
  First, starch-based plastics. Starch-based plastics are the most common biodegradable materials in our lives, such as disposable tableware. If you have the right tools, its main ingredient, starch, can also be made from starch in your kitchen.
  第二,聚乳酸(PLA)。你可能没听说过聚乳酸,但我们都知道乳酸。每个人都知道剧烈运动后你的身体有多痛。聚乳酸是由乳酸中的羟基和羧基脱水而成的聚合物。聚乳酸在整个生产过程中没有污染,其性能与许多工程塑料相似,与有机物具有良好的相容性。因此聚乳酸广泛应用于传统包装、汽车行业(门、轮辋、座椅等)、电子行业(CD、手机机壳等)。目前,有多种产品如手术缝合线、药物救济包装、人工骨折内固定材料等。
  Second, polylactic acid (PLA). You may not have heard of polylactic acid, but we all know about lactic acid. Everyone knows how painful your body is after strenuous exercise. Polylactic acid is a polymer formed by dehydration of hydroxyl and carboxyl groups in lactic acid. Polylactic acid has no pollution in the whole production process. Its performance is similar to many engineering plastics and has good compatibility with organic matter. Therefore, PLA is widely used in traditional packaging, automotive industry (door, rim, seat, etc.), electronic industry (CD, mobile phone case, etc.). At present, there are many kinds of products, such as surgical suture, drug relief packaging, artificial fracture internal fixation materials, etc.
  第三,聚羟基脂肪酸酯(PHA)——这应该是一个新词。PHA是在微生物中形成的一种内聚物,是一种天然高分子生物材料,近年来已成为生物功能材料的研究热点。与其他降解材料相比,PHA可以通过控制菌种和发酵过程来改变其组成。PHA可以像工程塑料一样硬,也可以像橡胶一样软。这种巨大的多样性使其得到了更广泛的应用,并成为近年来可降解材料研究的热点。
  Thirdly, polyhydroxyalkanoate (PHA) - this should be a new word. PHA is a kind of polymer formed in microorganisms and a natural macromolecule biomaterial. In recent years, it has become a research hotspot of biological functional materials. Compared with other degradable materials, PHA can change its composition by controlling the strain and fermentation process. PHA can be as hard as engineering plastics or as soft as rubber. This tremendous diversity has made it more widely used and become a research hotspot of biodegradable materials in recent years.
  上述几种完全独立于化石燃料的完全可降解材料对缓解能源危机具有重要意义。但由于没有化石燃料,原料主要依赖于食品和微生物,这些比传统化石燃料昂贵,难以大规模应用。从整体上看,并不是所有的可降解材料都符合工程塑料的标准,加工工艺还有待改进。因此,生物降解材料的普及还有很长的路要走。
  These completely degradable materials, which are completely independent of fossil fuels, are of great significance in alleviating the energy crisis. However, without fossil fuels, the raw materials mainly depend on food and microorganisms, which are more expensive than traditional fossil fuels and are difficult to be used on a large scale. On the whole, not all degradable materials meet the standard of Engineering plastics, and the processing technology needs to be improved. Therefore, the popularization of biodegradable materials still has a long way to go.
