폐분체 도료의 재활용 방안에 관한 연구 = A Study on Recycling The Waste Powder Coatings

다국어 초록 (Multilingual Abstract)

With the progress of industry, the much more demand of paint around us grows rapidly. However, the whole quantity of raw materials used to make powder coatings is presently imported to fill the domestic needs. Moreover, it is well known that the waste powder coatings from the domestic industries are mostly incinerated. The method of destructing the waste powder coatings by fire causes VOC to be generated, and this results in some serious environmental problems such as air pollution and so on. Therefore, the effective and proper measure must be devised to reuse the waste powder coatings for the purpose of eliminating waste of resources and avoiding the outflow of foreign currency. This study aims to make the plan to recycle the waste powder coatings, and its conclusion is drawn as follows:
First, it can be seen that the waste powder coatings with a weak electrostatic power restore gradually to the original state of electrostatic power through the process of fusion and retreatment.
Second, it can be estimated that those coatings, with the use of the cyclon, can be removed by dividing a powder of particles less than 10㎛.
Third, it can be ascertained that the possibility of reusing the waste powder coatings is proved when it is divided into particles by cyclon and a revolving screen after the process of fusion, rolling, crushing and pulverization.
