From Fast to Slow Degradation: Different Strategies to …
The reason for the slow degradation is a simple one. These materials do not exist in nature, and therefore, there are no naturally occurring organisms that can break them down effectively or at all. The chemical bonds in plastic materials are not accessible or “familiar” to bacteria in nature. Webb28 nov. 2024 · The degradation temperature of the materials can be adjusted to adapt to degradation requirements of different bottom hole temperatures by optimizing the ratio of raw materials. Although the fiber-type material has excellent flexibility and outstanding leak-proof and plugging performance, its degradation rate is slow, and strength is limited … how do you teach smeargle moves
