Introduction to the principle of total biodegradation

Total biodegradation is the conversion of fibrous plastics into water, carbon dioxide and other low-molecular-weight compounds based on the action of microbial strains. In this practical sense, plastics that cause displacement reactions based on chemical degradation can be called photodegradable plastics, and plastics that dissolve naturally based on the action of microorganisms such as germs, bacteria, and algae that exist in nature are called biodegradable. plastic. The basic principle of dissolving fully biodegradable plastics is to convert textile materials into carbon dioxide, water, honeycomb-like porous materials and low-molecular-weight phosphates based on various pathogens and enzymes, which can be used by green plants for photosynthesis of green plants. It is not easy to cause air pollution to the environment. The whole process of dissolving the biodegradable material is generally divided into two steps:The first step is that the tapioca starch filled here is corroded by microorganisms such as bacteria and pathogenic bacteria.,Dissipates slowly, causing porous material in the polymer to damage the structure,Expanded total area of 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 are easily degraded by microorganisms under the standard of soil stratification and burial. The whole process can be divided into two stages: the lytic enzymes of microbial strains are absorbed in theL-On the surface of the lactic acid bacteria beverage, under the action of neutralization, theL-The ester chain of the lactic acid bacteria beverage causes hydrolysis reaction and chain scission reaction, and the composition decreases from hundreds of thousands to less than hundreds of thousands, which leads to the reduction of the tensile strength of polylactic acid, the collapse and the expansion of the total area. The expansion of the total area also accelerates the hydrolysis reaction, making it further dissolved, converting it into a lactic acid bacteria drink with low composition, and carrying out one 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.
