生物（wù）降解顆粒製（zhì）成的塑料的原材料

根（gēn）據原材料的不同，常見的（de）生（shēng）物降解塑料少有以下幾種：聚己內酯（PCL）、聚乳酸（PLA）、聚羥基烷酸酯（zhǐ）(PHA)等等，下麵展開內容講講吧。

According to different raw materials, there are at least the following kinds of common biodegradable plastics: polycaprolactone (PCL), polylactic acid (PLA), polyhydroxyalkanoate (PHA), etc. Let's talk about it below.

聚己內酯（PCL）

Polycaprolactone (PCL)

這種塑料具有良好的生物降解性（xìng），熔點是62℃。分（fèn）解它的微生物廣（guǎng）泛（fàn）地分布在喜氣或（huò）厭氣條件下。作為可生物降解材（cái）料可（kě）把它與澱粉、纖維素類的材料混合在一起，或與乳酸聚合使用。

This kind of plastic has good biodegradability, and its melting point is 62 ℃. The microorganisms that decompose it are widely distributed under the conditions of euphoria or anorexia. As a biodegradable material, it can be mixed with starch and cellulose materials, or polymerized with lactic acid.

聚丁二酸丁二醇酯（PBS）及其共聚物

Polybutylene succinate (PBS) and its copolymers

以PBS（熔點為114℃）為基礎材料製造各（gè）種高分子量聚酯的技（jì）術已經達到工業化生（shēng）產水平（píng）。

The technology of manufacturing various high molecular weight polyesters based on PBS (melting point: 114 ℃) has reached the level of industrial production.

聚乳酸（PLA）

Polylactic acid (PLA)

隨（suí）著人們的環保意識的增強，解決塑料材料與環保的協調發（fā）展問（wèn）題愈加凸顯。可降解塑料是指在生產過程中加入（rù）一定量的添加劑(如澱粉（fěn）、改性澱粉或其它纖維素、光敏劑、生物降解劑等)，穩定性下降，較（jiào）容易在自然環境（jìng）中降（jiàng）解的塑料。

With the enhancement of people's awareness of environmental protection, the problem of solving the coordinated development of plastic materials and environmental protection has become increasingly prominent. Degradable plastics refer to plastics that are easy to degrade in the natural environment due to the decrease of stability due to the addition of a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizers, biodegradable agents, etc.) in the production process.

可降解塑料的出現，不僅擴（kuò）大（dà）了塑料功能，而且在一定程度上可（kě）緩解與環境的矛（máo）盾，節約和代替石油資源，有效地白色汙染，保護環境（jìng）。

The emergence of degradable plastics not only expands the function of plastics, but also alleviates the contradiction with the environment to a certain extent, saves and replaces oil resources, effectively eliminates white pollution and protects the environment.

聚（jù）乳（rǔ）酸(pla)是一（yī）種新型的生物降解材料，使用可再生（shēng）的植物資源(如玉米)所提（tí）出的澱粉原（yuán）料製成，澱粉原料經由發酵（jiào）過程製成（chéng）乳酸，再（zài）通過化學合成（chéng）轉換成聚乳酸。盡管聚乳酸具有良好的生物降解性，但聚乳酸還存在生產成本高等問題，其力學和加工性能還有待進一步提高。

Polylactic acid (PLA) is a new type of biodegradable material, which is made of starch raw materials proposed by renewable plant resources (such as corn). The starch raw materials are made into lactic acid through fermentation, and then converted into polylactic acid through chemical synthesis. Although PLA has good biodegradability, it still has the problem of high production cost, and its mechanical and processing properties need to be further improved.

聚羥基烷（wán）酸酯（zhǐ）(PHA)

Polyhydroxyalkanoates (PHA)

利用可再（zài）生資（zī）源得到的生（shēng）物降解顆粒降解塑料，把脂肪（fáng）族聚酯和澱（diàn）粉混合在一起，生產可降解（jiě）性塑料的（de）技術（shù）也已經研究成功。在歐美（měi），澱粉和脂（zhī）肪族聚酯的共混物被廣（guǎng）泛用來生產垃圾袋等（děng）產品。上規模大、銷售好的是意大利的Novamont公司，其（qí）商品名為Mater-bi，公司的產品在（zài）歐洲和美國有較大量的應用。

The technology of using biodegradable particles obtained from renewable resources to degrade plastics and mixing aliphatic polyester and starch to produce degradable plastics has also been successfully studied. In Europe and the United States, the blend of starch and aliphatic polyester is widely used to produce garbage bags and other products. Novamont, an Italian company with a trade name of mater Bi, has a large scale and good sales in the world. Its products are widely used in Europe and the United States.
