Read： 1471 Time：15months ago Source：Transform the World with Simplicity

With the popularization of modern production and consumption methods, plastic products have become ubiquitous in our daily lives, but the resulting plastic pollution has become more and more serious. How to solve this problem has become the focus of attention, and dissolving plastics has become an environmentally friendly, high-tech treatment method.

so what can dissolve plastic? in fact, this is a relatively complex chemical problem, under normal circumstances the use of chemical solvents is a common method, such as acid, alkali, organic solvents. However, there are many problems in the use of these solvents, such as toxic, volatile, unsafe and not environmentally friendly.

recently, a new method of dissolving plastics has gained widespread attention, and that is the use of supercritical fluids. This kind of fluid means that under the temperature and pressure conditions above the critical point, the interface between gas and liquid disappears and becomes a state between gas and liquid, which has extremely strong dissolving power.
there are many advantages
using supercritical fluids to dissolve plastics. The conditions of the solvent are neutral, non-toxic, harmless, easy to recycle, and very environmentally friendly. The dissolving power of supercritical fluid is very strong, can quickly dissolve the plastic, and only need a small amount of use can achieve the desired effect. Finally, the method of using supercritical fluid to dissolve plastics has been widely used, and there are many practical cases for reference, providing strong technical support.

Of course, there are problems with supercritical fluids to dissolve plastics. Supercritical fluids require certain heating and pressurization conditions to reach a critical state, requiring some special treatment on equipment and materials. The cost of supercritical fluids is high and cost-effectiveness considerations need to be made.

In general, the use of supercritical fluids to dissolve plastics is a very high-tech method and an environmentally friendly, healthy and safe solution. In the future, with the continuous development of technology, this method will become more popular, and make greater contributions to reducing plastic pollution, protecting the environment, and promoting energy conservation and emission reduction.
