These excellent properties have been widely used in various industrial fields. The application of the polymer is very wide, and the polymer is spread to clothes, food, lives and rows of people, departments of national economy and advanced technology. The advent of functional polymers has enabled the use of synthetic polymers to develop to a more elaborate and advanced level, playing an important role in not only promoting industrial and agricultural production and sophisticated technologies, but also exploring the mysterious nature of life, combating cancer and treating genetic diseases. However, the polymer is flammable and easy to age, often has harmful monomers in the polymer, cannot be degraded, cannot be corroded by bacteria, and cannot be absorbed by soil. The product is discarded after being used in large amount, which causes serious public nuisance. There is an urgent need to develop polymer articles that do not bring harmful substances in the natural environment.

The traditional polymer degassing method comprises the steps of continuously blowing nitrogen into an atmospheric bin by utilizing the atmospheric bin, and taking away harmful gases through the nitrogen; if the residence time in the dead zone is too long, yellowing is easy to occur, and the yellowing polymer material can pollute normal materials and can be decomposed to influence the integral degassing effect; if the retention time is too short, the aim of removing harmful gases cannot be achieved; finally, the waste of manpower and material resources is caused.
