全生物降解是依据微生物菌种的作用将纤维材料塑胶转换成水、二氧化碳及其他低分子式化合物。在这个现实意义上,可将依据化学降解体现而造成置换反应的塑胶称作光降解塑料,将依据自然界存在的病原菌、病菌和藻类植物等微生物菌种作用而自然溶解的塑料称作生物降解塑料。生物降解塑料的溶解基本原理主要是依据各式各样病原菌及酶将纺织材料转换成二氧化碳、水、蜂巢状的多孔材料和低分子式的磷酸盐,它们可被绿植用于植物光合作用,不易对地理环境造成空气污染。生物降解塑料的溶解整个过程一般分为二步:步是添充在这里在其中的土豆淀粉被病菌、病原菌等微生物菌种腐蚀,慢慢消散,在聚合物中造成多孔材料损坏结构,扩张了聚合物的总面积;步是剩下的纤维材料聚合物在病原菌和水解作用下进一步造成各式各样置换反应,使分子式解链成低成分碎片,保证被微生物菌种基础代谢的水准。

Total biodegradation is the conversion of fiber materials and plastics into water, carbon dioxide and other low molecular formula compounds according to the action of microbial strains. In this practical sense, the plastic that causes the replacement reaction according to the embodiment of chemical degradation can be called photodegradable plastic, and the plastic that is naturally dissolved according to the action of pathogenic bacteria, bacteria, algae and other microbial strains in nature can be called biodegradable plastic. The basic principle of the dissolution of biodegradable plastics is mainly based on various pathogens and enzymes to convert textile materials into carbon dioxide, water, honeycomb porous materials and low molecular phosphate. They can be used by green plants for plant photosynthesis and are not easy to cause air pollution to the geographical environment. The whole process of dissolving biodegradable plastics is generally divided into two steps: the first step is that the potato starch added here is corroded by microbial strains such as bacteria and pathogens, which slowly dissipates, causing damage to the structure of porous materials in the polymer and expanding the total area of the polymer; The next step is that the remaining fiber material polymer will further cause various replacement reactions under the action of pathogenic bacteria and hydrolysis, so that the molecular formula can be broken into low component fragments to ensure the level of basic metabolism by microbial strains.
聚L-乳酸菌饮料在土壤分层掩埋规范可致被微生物降解,其整个过程可划分为两个阶段:是微生物菌种的溶解酶吸咐在聚L-乳酸菌饮料表面上,在水解作用下,聚L-乳酸菌饮料的酯链造成水解反应、断链反应,成分从数十万降至数十万以下,导致聚乳酸抗拉强度降低、崩碎。总面积扩张。总面积的扩张又了水解反应,使之进一步溶解,转换成成分低的乳酸菌饮料,开展一次溶解。其次是水解反应产生的乳酸菌饮料,在土壤分层中微生物菌种的代谢作用下,转换成二氧化碳和水。
Polyl-lactic acid bacteria beverage can be degraded by microorganisms when buried in the soil layer by layer. The whole process can be divided into two stages: the dissolved enzyme of microbial bacteria is absorbed on the surface of polyl-lactic acid bacteria beverage. Under the action of hydrolysis, the ester chain of polyl-lactic acid bacteria beverage causes hydrolysis reaction and chain breaking reaction, and the composition decreases from hundreds of thousands to below hundreds of thousands, resulting in the reduction of tensile strength and disintegration of polylactic acid. Total area expansion. The expansion of the total area also the hydrolysis reaction to further dissolve it and convert it into a lactic acid bacteria beverage with low composition to carry out one-time dissolution. The second is the lactic acid bacteria beverage produced by hydrolysis reaction, which is converted into carbon dioxide and water under the metabolism of microbial strains in soil stratification.
