Abstract

The wide application of chemical substances, although it brings great convenience to people’s lives, but it is difficult to degrade in the natural environment of the chemical composition once the long-term retention of people’s living space, it will seriously jeopardize the living and ecological environment. The use of biodegradation technology can effectively reduce the harm caused by chemical substances. The use of biodegradation technology can effectively reduce the harm caused by chemical substances. Based on the above background, the biodegradation technology for the structure change reaction of polymer polylactic acid (PLA) was studied. In the process of structure change reaction of polymer PLA, the cyclic degradation model is established and the thermal change reaction is analyzed, so as to find out the degradation weight loss rate and thermal properties, and complete the analysis of the thermal degradation behavior of polymer PLA. Clarify the basic concepts of polymer biodegradation, classify them, then prepare raw materials, simulate the biodegradation process, and analyze the specific implementation based on the degradation results.
