Description

Technical Field

[0001] The utility model relates to the technical field of sealant production, in particular to a continuous production device for single-component silicone sealant used in nuclear power plants. Background Art

[0002] One-component silicone sealant for nuclear power plants is a high-performance sealing material designed specifically for the special environment of nuclear power plants. This sealant also has excellent radiation resistance, can maintain the stability of its physical and chemical properties in a strong radiation environment, and effectively prevent the leakage of radioactive substances. In addition, it has high bonding strength and can firmly adhere to the surface of various substrates, such as metal, glass, ceramics, etc., to form a long-lasting and reliable seal. In nuclear power plants, one-component silicone sealants are often used for sealing key parts such as reactor vessels, piping systems, valves, etc., providing important guarantees for the safe operation of nuclear power plants.

[0003] However, during the stirring process in the reactor, the silicone sealant is very easy to stick to the wall due to its glue properties. When discharging the material, it will not only lead to a reduction in output, but also cause uneven reaction of the raw materials, resulting in waste. In addition, the silicone sealant that sticks to the wall will solidify after the equipment is shut down. It is not only difficult to clean, but also will increase the resistance of the equipment when it is started next time, thereby increasing energy consumption. After searching, it was found that the technical solution provided by the utility model with application number CN202220411403.5 also has the above-mentioned problems. Utility Model Content
