生物降解塑料的相关降解方式参考

生物降解颗粒按其生物降解过程大致可分为两类，下面就让生物降解颗粒生产厂家来为您讲解一番吧。

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

一类为完全生物降解材料，如天然高分子纤维素、人工合成的聚己内酯等，其分解作用主要来自：①由于微生物的迅速增长导致塑料结构的物理性崩溃；②由于微生物的生化作用、酶催化或酸碱催化下的各种水解；③其他各种因素造成的自由基连锁式降解。

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.

另一类为生物崩解性材料，如淀粉和聚乙烯的掺混物，其分解作用主要由于添加剂被破坏并削弱了聚合物链，使聚合物分子量降解到微生物能够消化的程度，分解为二氧化碳（CO2）和水。聚乙烯醇为可生物降解树脂，故淀粉基聚乙烯醇塑料可完全生物降解。

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.

目前生活中我们常见的塑料制品大部分是部分降解的，其中以淀粉基系的塑料制品的降解效果佳，华潍自主研发的膨润土改性淀粉复合材料（BMSC）是以淀粉为基质通过熔融插层塑化挤出工艺生产的完全生物降解材料。材料不含聚烯烃塑料，具有高性价比、天然防静电性、低碳环保的特性，并且产物均是可以循环再利用的。

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，降解时间随不同环境变化而变化，例如在干燥环境下，降解时间则会长些，降解时间也是可控的。

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，光氧降解塑料在实际中并不耐用，且在用后既不能被回收再生，也不能被堆肥，反而对两种处理方式都会造成干扰——降低再生塑料性能，污染堆肥产物。全球各大研究机构和公益机构目前都在倡议禁止这种塑料的生产，直到有证据证明其在短时间内可以完全降解。

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.

物降解，指材料在特定环境下，通过微生物作用，完全转化成二氧化碳和水。可以将聚酯短链变成二氧化碳的微生物包括细菌、真菌和原生生物,它们分泌的一种酶可将聚酯键分解。

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.
