[0002] In the field of nuclear cleaning and radioactive decontamination, strippable coatings, as an efficient and environmentally friendly cleaning material, have broad application prospects. However, in its production process, the reactor is a key preparation equipment, and its heating method directly affects the quality and production efficiency of the coating.

[0003] At present, most reactors on the market use the outer wall heating method, that is, by installing heating elements, such as electric heating wires, electric heating tubes, etc., on the outer wall of the reactor, heat is transferred to the internal materials through the outer wall. Although this heating method is simple, it has significant defects. Since the heat needs to be conducted to the internal materials through the wall of the reactor, a large amount of heat will be lost during the conduction process, resulting in low heating efficiency. At the same time, due to the uneven distribution of materials inside the reactor, the outer wall heating method often causes uneven heating of the materials, which makes the reaction speed inside the materials slower, affecting the uniformity and stability of the coating.

[0004] In addition, in the preparation process of nuclear cleaning and radioactive decontamination coatings, the quality requirements for the coatings are extremely high. It is necessary to ensure that the coatings are free of impurities and pollution, and have good strippability and adhesion. However, due to the uneven heating and low heating efficiency caused by the outer wall heating method, the coatings often have problems such as unstable quality and uneven composition during the preparation process, making it difficult to meet the high standards of nuclear cleaning and radioactive decontamination.

[0005] Therefore, developing a reactor that can evenly and efficiently heat the inside of the material and improve coating quality and production efficiency has become an urgent problem to be solved in the current field of nuclear cleaning and radioactive decontamination. Utility Model Content
