The principle of total biodegradation

Full biodegradation is based on the action of microorganisms to convert fiber materials and plastics into water, carbon dioxide and other low molecular formula compounds. In this practical sense, plastics that undergo substitution reactions based on chemical degradation can be called photodegradable plastics, and plastics that naturally dissolve under the action of microorganisms such as pathogenic bacteria, germs, and algae that exist in nature are called biodegradable plastics. . The basic principle of the dissolution of biodegradable plastics is mainly based on the conversion of textile materials into carbon dioxide, water, honeycomb-shaped porous materials and low-molecular-weight phosphates based on various pathogenic bacteria and enzymes. They can be used by green plants for plant photosynthesis and are not easy to Air pollution to the geographical environment. The whole process of dissolving biodegradable plastics is generally divided into two steps:The first step is to add that the potato starch in it is corroded by germs, pathogens and other microorganisms,Dissipates slowly, causing porous material in the polymer to damage the structure,expands the total area of the polymer;The first step is that the remaining fibrous material polymer further causes various substitution reactions under the action of pathogenic bacteria and hydrolysis, so that the molecular formula is melted into low-component fragments, and the level of basal metabolism by microorganisms is guaranteed.polyL-Lactic acid bacteria beverages can be degraded by microorganisms in soil layered burial.L-On the surface of lactic acid bacteria beverage, under the action of hydrolysis, polymerizedL-The ester chain of the lactic acid bacteria beverage causes hydrolysis reaction and chain scission reaction, and the ingredients are reduced from hundreds of thousands to less than hundreds of thousands, resulting in the reduction of the tensile strength of polylactic acid and the collapse. total area expansion. The expansion of the total area promotes the hydrolysis reaction to further dissolve it, convert it into a lactic acid bacteria drink with low ingredients, and carry out a dissolution. The second is the lactic acid bacteria beverage produced by the hydrolysis reaction, which is converted into carbon dioxide and water under the metabolism of the microbial species in the soil stratification.
