Release agents for internal use are widely used in industrial production, and their biodegradability and environmental friendliness are increasingly attracting attention.
First, biodegradability is one of the key indicators to measure the environmental friendliness of Release agents for internal use. The biodegradation process usually involves the decomposition of release agent molecules by microorganisms. Some Release agents for internal use contain natural oil components, such as castor oil-based release agents, which are relatively easy to be decomposed and utilized by microorganisms. Under suitable environmental conditions, such as the presence of specific bacteria and fungal communities and sufficient oxygen and moisture, they can be gradually decomposed into harmless carbon dioxide, water and biomass. However, some traditional Release agents for internal use contain difficult-to-degrade organic synthetic compounds, such as certain long-chain hydrocarbons or fluorinated compounds, which may remain in the natural environment for a long time, causing potential pollution to soil, water bodies, etc., and may accumulate in organisms, affecting ecological balance and biological health.
Secondly, the evaluation of the environmental friendliness of Release agents for internal use also needs to consider its environmental impact throughout its life cycle of production, use and disposal. In the production process, if the synthesis process of the release agent requires a lot of energy consumption, produces toxic and harmful by-products, or involves unsustainable raw material mining, even if it has a certain degree of biodegradability, the overall environmental friendliness will be greatly reduced. During use, the volatile matter of the release agent may affect the indoor and outdoor air quality. For example, the emission of certain volatile organic compounds (VOCs) will aggravate air pollution and form harmful pollutants such as ozone. In the waste treatment stage, if the release agent is difficult to completely remove from the surface of the product or has an adverse effect on the performance of the recycled material during the recycling process, it will also lead to resource waste and increased environmental pressure.
Furthermore, the current evaluation methods and standards for the environmental friendliness of Release agent for internal use are still being improved. Common evaluation methods include laboratory simulated biodegradation experiments, such as quantifying its biodegradability by measuring the degradation rate, degradation rate constant and other parameters of the release agent under specific microbial culture conditions. At the same time, there are also environmental impact assessment models that comprehensively consider the entire life cycle, such as life cycle assessment (LCA), which can comprehensively analyze the environmental load of release agents from raw material acquisition to final disposal, such as resource consumption, energy consumption, and pollutant emissions, so as to more scientifically judge their comprehensive impact on the environment.
Finally, in order to improve the environmental friendliness of Release agent for internal use, the industry is actively exploring various ways. On the one hand, new green and environmentally friendly release agent formulas are developed, and rapidly biodegradable raw materials are used to replace traditional difficult-to-degrade ingredients; on the other hand, the production process is optimized, energy consumption and pollutant emissions are reduced, and environmental management during use is strengthened, such as using a closed circulation system to reduce volatilization and leakage of release agents, so as to achieve the sustainable application of Release agent for internal use in industrial production and reduce the negative impact on the environment.
