MindMap Gallery Balance of Plastic Degradation Process
The balance of the plastic degradation process is influenced by various factors such as light, temperature, humidity, and microbial species. Mechanisms such as photodegradation, thermal degradation, and biodegradation act on the plastic structure. Strategies such as adding degradation aids, adjusting formulas, or optimizing degradation environments can effectively promote plastic degradation, reducing environmental pollution.

Circular Economy and Chemical Balance focuses on the concepts, principles, and practical cases of circular economy. It also analyzes the principles of mass and energy conservation in chemical reactions, revealing the intrinsic link between circular economy and chemical balance. By optimizing resource utilization and reducing waste emissions, circular economy and chemical balance promote each other, jointly driving sustainable development.
The influence of pressure on gas reactions mainly manifests in changes to the chemical equilibrium position. According to Le Chatelier's principle, increasing pressure typically shifts reactions with a decrease in the number of gas molecules toward the forward direction. The mole concept is crucial in gas reactions, determining the quantities of reactants and products. Additionally, pressure changes have practical implications in industrial production, environmental protection, and energy conversion.
