生物降解塑料的相關降解方式參考

生物降解顆粒按（àn）其生物降解過程（chéng）大致可分為兩類，下麵就（jiù）讓（ràng）生物降解顆粒生（shēng）產廠家來（lái）為您（nín）講解一（yī）番吧。

Biodegradable particles can be roughly divided into two categories according to their biodegradation process. Let the manufacturers of biodegradable particles explain it for you.

一類為完全生物降解材料，如天然高分子纖維素、人工合成的聚己內酯等，其分解（jiě）作用主要來自：①由於微生物的迅速增長導致塑料結構（gòu）的物理性崩潰；②由於微生物的生化（huà）作用、酶催化或酸堿催化下（xià）的（de）各種水（shuǐ）解；③其他（tā）各種因素造成的自由基連鎖式降解（jiě）。

One type is completely biodegradable materials, such as natural high molecular cellulose and synthetic polycaprolactone, whose decomposition mainly comes from: ① physical collapse of plastic structure due to rapid growth of microorganisms; ② Various hydrolysis due to biochemical action of microorganisms, enzyme catalysis or acid-base catalysis; ③ Free radical chain degradation caused by various other factors.

另一類為生物崩解性材料，如澱粉（fěn）和聚乙烯的摻混物，其（qí）分解作（zuò）用主要由（yóu）於添加劑被破壞並削弱了（le）聚合物鏈，使聚合物分子量降（jiàng）解到微生物能夠消（xiāo）化的程度，分解為二氧（yǎng）化碳（CO2）和水。聚乙烯醇為可生物降解樹脂，故澱粉基聚乙烯醇塑料可完（wán）全生（shēng）物降解。

The other type is biodisintegrating materials, such as the mixture of starch and polyethylene. The decomposition effect is mainly due to the destruction of additives and the weakening of polymer chains, so that the molecular weight of polymers is degraded to the extent that microorganisms can digest, and decomposed into carbon dioxide (CO2) and water. Polyvinyl alcohol is a biodegradable resin, so starch based polyvinyl alcohol plastic can be completely biodegradable.

目前生活中我們常見的塑料製品大部分是部分降解（jiě）的，其中以澱粉基係（xì）的塑料製品的降解效果佳，華濰自主研發的膨潤土改性澱粉複合材（cái）料（BMSC）是以澱粉為基質通（tōng）過（guò）熔融插層塑（sù）化擠（jǐ）出工藝生產的完全生物降解（jiě）材料。材料不含聚烯（xī）烴塑料，具有高性價比、天然防靜電性、低碳環保的特性，並且產物均是可以循環再（zài）利用的。

At present, most of the common plastic products in our life are partially degraded, and the starch based plastic products have the best degradation effect. The bentonite modified starch composite (BMSC) independently developed by Huawei is a fully biodegradable material produced by the melt intercalation plasticization extrusion process with starch as the matrix. The material does not contain polyolefin plastic, has the characteristics of high cost performance, natural antistatic, low-carbon and environmental protection, and the products can be recycled.

甚，降解時間隨不同環境（jìng）變化而變化，例如在幹燥環境下，降解時間則會長些，降解時間也是可控的。

Even, the degradation time varies with different environments. For example, in a dry environment, the degradation time is longer and the degradation time is controllable.

此外，光氧降解（jiě）塑料在實際（jì）中並不耐用，且在用後既不能被回收再生，也不能被堆肥，反而對兩種處理方式（shì）都會造成幹擾——降低再（zài）生塑料性能，汙染堆肥產物。全球各大（dà）研究（jiū）機構和公益機構目前都在倡議禁止這（zhè）種塑料的生產，直到有證據證（zhèng）明其在短時間內可（kě）以完全降解。

In addition, the photo oxidative degradable plastics are not durable in practice, and can not be recycled or composted after use. On the contrary, it will interfere with both treatment methods - reduce the performance of recycled plastics and pollute compost products. All major brand research institutions and public welfare institutions around the world are currently proposing to ban the production of this plastic until there is evidence that it can be completely degraded in a short time.

物（wù）降解，指材料在特定環（huán）境下，通過微生物作用，完全轉化成二氧化碳和水。可以將聚酯短鏈變成二氧化碳的微（wēi）生物包括細菌（jun1）、真菌（jun1）和原生生物,它（tā）們分泌的（de）一種酶可將聚酯鍵分（fèn）解。

Biodegradation refers to the complete conversion of materials into carbon dioxide and water through microbial action in a specific environment. Microorganisms that can convert polyester short chain into carbon dioxide include bacteria, fungi and protozoans. An enzyme secreted by them can decompose polyester bonds.
